I've made a cool processing project that I would like to embed on the web; however, it uses 3rd party Java libraries to access an sqlite database. For this reason, the normal export-to-javascript which has worked well for me in the past is just not capable enough here. How can I make my Processing project into a Java applet that will allow it to be run remotely?
This depends upon what version of Processing you are using...
It was only in the final move to 2.0 that they got rid of the 'Export to Applet' option, so if you can make do with a 2.x-beta version, you're golden.
Of course, that's just through the PDE - so failing the ability to move to an earlier version, the library itself should be able to handle it still, from a different IDE, say Eclipse or NetBeans...
I guess the other option would be to see if you can port your library to a JavaScript library ?

I'm coming from NetBeans and evaluating others and more flexible IDEs supporting more languages (i.e. Python) than just php and related.
I kept an eye on Eclipse that seems to be the best choice; at the time I was not able to find an easy solution to keep the original project on my machine and automatically send / syncronize the files on the remove server via sftp.
All solutions seems to be outdated or stupid (like mounting a smb partition or manually send the file via an ftp client!
I'm not going to believe that an IDE like Eclipse doesn't have a smart solution of what I consider a basic feature of an IDE, so I think I missed something... On Eclipse forums I've seen the same question asked lots of time but without any answer!
Some suggestions about is strongly apreciated otherwise I think the only solution is stick on one IDE each language I use that seem to be incredible on 2018.
I'm developing on MacOS and the most interesting solution (kDevelop) fails on building with MacPorts.
Thank you very much.
RSE is a very poor solution, as you noted it's a one-shot sync and is useless if you want to develop locally and only deploy occasionally. For many years I used the Aptana Studio suite of plugins which included excellent upload/sync tools for individual files or whole projects, let you diff everything against a remote file structure over SFTP when you wanted and exclude whatever you wanted.
Unfortunately, Aptana is no longer supported and causes some major problems in Eclipse Neon and later. Specifically, its editors are completely broken, and they override the native Eclipse editors, opening new windows that are blank with no title. However, it is still by far the best solution for casual SFTP deployment...there is literally nothing else even close. With some work it is possible to install Aptana and get use of its publishing tools while preventing it from destroying the rest of your workspace.
Install Aptana from the marketplace.
Go to Window > Preferences > Install/Update, then click "Uninstall or update".
Uninstall everything to do with Aptana except for Aptana Studio 3 Core and the Aptana SecureFTP Library inside that.
This gets rid of most, but not all of Aptana's editors, and the worst one is the HTML editor which creates a second HTML content type in Eclipse that cannot be removed and causes all kinds of chaos. But there is a workaround.
Exit Eclipse. Go into the eclipse/plugins/ directory and remove all plugins beginning with com.aptana.editor.* EXCEPT FOR THE FOLLOWING which seem to be required:
com.aptana.editor.common.override_1.0.0.1351531287.jar
com.aptana.editor.common_3.0.3.1400201987.jar
com.aptana.editor.diff_3.0.0.1365788962.jar
com.aptana.editor.dtd_3.0.0.1354746625.jar
com.aptana.editor.epl_3.0.0.1398883419.jar
com.aptana.editor.erb_3.0.3.1380237252.jar
com.aptana.editor.findbar_3.0.0.jar
com.aptana.editor.idl_3.0.0.1365788962.jar
com.aptana.editor.text_3.0.0.1339173764.jar
Go back into Eclipse. Right-clicking a project folder should now expose a 'Publish' option that lets you run Aptana's deployment wizard and sync to a remote filesystem over SFTP.
Hope this helps...took me hours of trial and error, but finally everything works. For the record I am using Neon, not Oxygen, so I can't say definitively whether it will work in later versions.
some questions:
i unzipped the full offline distribution (400+ mb) to C:\Program Files\Play2.4
Unzipping created a directory "activator-dist-1.3.5" within which are bin, lib, repository, templates, etc.
i assume i put the contents of activator-dist-1.3.5 into C:\Program Files\Play2.4?
i setup an user environment variable name: PLAY_HOME, value: C:\Program Files\Play2.4 and then added ;%PLAY_HOME% to the end of the system variable "Path"
i've tried calling "play" from dos both with and without "activator-dist-1.3.5" directory and both return "play is not recognized as an internal or external command"
some other answers to this question mention the root play dir should have "play.bat" but all i see is "activator.bat"
i read readme.html and opened activator.bat, it launched a dos window, which promptly closed.
http://localhost:8888/home goes nowhere.
For those who don't yet speak "play", what is Activator UI?
Since play 2.3, the play command was replaced with the activator command. Take a look to this.
If you put the folder activator-dist-1.3.5 into C:\Program Files\Play2.4 then your enviroment variable must be set to C:\Program Files\Play2.4\activator-dist-1.3.5\bin. You can also put that path directly into the PATH environment variable.
Activator UI is a web aplication that helps you create play applications. You can think of it as the graphical version of the activator command line tool. Here is the documentation
ok, here is what ive figured out:
the environment variable has to point to the bin directory (thx Victor)
from w/in dos window (the "console"), cd to the the root play dir (not bin) and type "activator" not "play"
all other documentation and stackoverflow answers refer to the pre 2.3 versions of play and will not help you.
then a bunch of stuff happens: online maven call (even though i downloaded the offline dist) and a bunch of calls to the play root dir/repository for jars.
of course localhost:9000 and localhost:8888 still get connection refused.
now if you manually open activator.bat in root play dir it launches another dos window, makes a network call (firewall allow) and opens a browser win to: http://127.0.0.1:8888/home which is some sort of "welcome to activator" screen with sample apps .. sort of like the tomcat mngt page.
i hope to only define and start/stop apps from w/in my IDE, so eventually i'll be looking for how to disable this default activator behavior
next up.. how to setup intelliJ:
i went here: https://www.playframework.com/documentation/2.4.x/IDE and defined an SBt task instead of a play task in run/debug configurations of my new project.
now project start makes maven calls for jars but then dies on:
[error] Server access Error: Connection timed out: connect url=...repo.typesafe.com/typesafe/ivy-releases/org.apache/apache/14/jars/apache.jar
stopping and restarting did a bunch more maven calls (really slow) but eventually "done updating" and localhost:9000/ now shows welcome screen :)
not completely painless but certainly simpler than a spring app
onEdit:
sorry play, but i've moved to spring boot because:
i create new projects by copying existing and making changes. its much faster than creating a new proj from scratch. Thus the activator thing (which does not work) is not useful to me and just represents a security prob (like apache web management screen) that need be disabled
no where is there a clear, concise and complete list of settings to get play running correctly in intelliJ (the 2nd most popular IDE avail)
asynchronous, non-blocking and micro services are not unique to play and spring (or others) can be made to work in a similar fashion
We have so many technologies to learn and it does'nt make sense to invest a lot of time mastering one with limited corporate buy in
i want to stop/start from w/in my IDE and not have to have a bunch of dos windows open. i know this is possible in play, but documentation makes it feel as though its not the preferred method
although i appreciate that the play directory structure is less flexible, its still not the command/controller/manager/dao/model world that is the most often seen for java apps
i investigated play because spring was getting to the point of having too many ways to configure too many things in too many places that were documented differently across versions. Also, large sub-projects in spring (like security) garnered their own books on the subject because they were so complex to figure out. At the end of the day, the level of security (for example) needed (or the manner in was implemented) went beyond what avail via simple configuration and after all the customization we were left wondering whether spring security just got in the way instead of providing real time saving and usefulness.
Spring boot hopes to help in that its an opinionated configuration where a collection of configuration basic best practices are encouraged/enforced.
and lets re real.. time saving on a slightly more concise language or a slightly different proj structure or dynamic class loading is not whats important.
The majority of time spent on projects, by far, is the time spent researching, thinking and investigating architectures, technologies, databases and presentation schemes.
I prob only spend 20% of my time coding and 80% trying to figure out the strategic vision needed to create software that has maximum usefulness and is "future friendly" (not needing to be re-coded every 3 years)
so far i've deleted my project and recreated about 10 times.. trying diff settings, still w/ no luck.
checking google play mailing group, i tried to create via activator ui.. but could not launch activator until i deleted the RUNNING_PID file in the play root dir
now i'm back at: http://127.0.0.1:8888/home to create a new app
at create new proj i get error: "cannot find project/build.properties".
lets try adding a blank build.properties where its expected.. nope, error: "destination already has files in it"
not that it really matters, sample templates have no knowledge of IDE and thus provide no insight into how to configure IJ. New\Import project does not list IJ as an option in choosing an external model
...whatever...
"Mr McKitrick.. after careful consideration ..."
trying to get working in IJ 14 ultimate:
jamesward.com has a tutorial and video, but its for older versions of IJ and play and only covers a small % of necc. configurations.
jetbrains has a tutorial but it also only covers play 2 and older IJ which does not translate to 14 and 2.4
https://www.playframework.com/documentation/2.4.x/IDE helps, but just w/ setting up an SBT Task
all the other project settings are a mystery for example:
project source need be defined to even show your project directories in proj tree
facet setup add does not list scala as option
why is scala lib pointing to users[me].ivy2\cache..? (i would think all necc libs are w/in play root\lib
should i setup a global lib pointed to play\lib?
run/debug config need env var pointed to PLAY_HOME?
basically all classes are not being resolved in IJ editor.
project structure lists 109 problems like:
Library SBT: joda-time:joda-time:2.3:jar is not used [Fix]
seems like i'm missing a global lib definition.
i'm able to get my app running, but i dont know how useful its going to be when the 2nd most popular IDE throws red bars at every import: "play."
I recently started learning about Android app development. It's also my first experience with the Java language.
There are some debugging tools that I want to incorporate into my app development in a form of Java package dependency. For obvious reasons, I would like to include it only for debug builds.
In iOS, we can use build configuration to link with debugging libraries only for debug builds, and use macros to remove parts of code that deals with debugging. This makes it really easy to switch between debug and production builds. Anyway to achieve the same for Android?
So far, the closest I got is using Maven profiles to overwrite properties files, which gets loaded by the application, but this requires that the debugging libraries are still imported.
To clarify my question, here is what I want to do:
I built a library that will let you browse the SQLite database on your browser. It's really useful for debugging purposes, but I don't want to ship my app with the library.
Another purpose is to use HockeyApp. HockeyApp provides two features: Update notification, and crash reporting. I need three different builds for this to work:
Production: Crash reporting On, Update notification Off
Beta: Both On
Debug: Both Off
In the manifest's <application>, you can set the debuggable attribute. Eclipse does this for you automatically if you omit the attribute. Debug builds have debuggable=true, well exported builds have debuggable=false.
This affects Log.d, and you can conditionally check in code using the following:
boolean isDebuggable = (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE));
In addition to Maven, one way is to use a dependency injector like Dagger
By building on standard javax.inject annotations (JSR-330), each class is easy to test. You don't need a bunch of boilerplate just to swap the RpcCreditCardService out for a FakeCreditCardService.
Dependency injection isn't just for testing. It also makes it easy to create reusable, interchangeable modules. You can share the same AuthenticationModule across all of your apps. And you can run DevLoggingModule during development and ProdLoggingModule in production to get the right behavior in each situation.
One way to solve this is to check the return value of PackageManager#getInstallerPackageName. It returns null if the apk was installed manually through adb, through a web page, or through a service like HockeyApp. In fact, I recently added a similar check to our sdk, see this commit.
Note that this solution is only reliable if you only distribute your (paid) app though Google Play. Last time I checked, alternative stores like the Amazon App Store or AndroidPIT were not setting the installer source (it is possible to set it since API level 11, see PackageManager#setInstallerPackageName).
Another option is to check the package name at runtime. For your beta builds, you would append ".beta" to the package name and then check for this suffix to enable in-app updates or debug stuff. You can do this by moving your code base into a library project and set up two app projects that reference this library project: one for the store app, one for the beta app. Our use aapt with the option --rename-manifest-package to change the package name of beta builds (see details here).
do you have use BuildConfig.DEBUG, this is created by android adt tool
/gen/BuildConfig
Trying to run basic java application (backbone.js and jax-rs) I was pleasantly surprised that modifying js or html file in src/main does not require application rebuild. Just refreshing it in browser is enough to update the application.
However changing java file, I can't find how to make application be updated locally.
Using Eclipse it's automatically compiled into target/classes, however applicaiton is not updated in browser. I can't find any bees command to cause update. I don't see compile command also.
Killing running tomcat and 'bees run' makes the trick, but the question is, if instant update is possible in case of basic java web application?
I'm not sure how to do it with a normal Java app. One option would be to use Playframework has this auto-reloading stuff built in, and is supported well on CloudBees. http://wiki.cloudbees.com/bin/view/RUN/Playframework
You need to use something like JavaRebel or Javeleon if you wish to reload Java classes in a running application.
I have installed SIPDROID. I made three account at sip2sip.
After that I have configured application using one of that account. Application works fine.
Question is: If I make multiple call to the same phone using SIP is there anyway to handle all calls at a same time?
Another incoming call is not displaying on mobile screen while first call is continue.
The first call getting picked up but what about the second call which is coming during first call.
Even second call is not displaying on the screen. Confused !!
Sipdroid that I what started with but after researching on it and from developers reviews I found that application has some missing functionality like multiple call and transferring calls etc...
I don't know but may who is expert in sip stack or have time to do can implement missing functionality but I am neither one of them so my desire to get an application that have all this functionality and by modifying it I can integrate into my application and csipsimple is the answer.
However its not easy job to build csipsimple into windows environment but there is hack how to do it. so carefully read its wiki about building project into window environment.
According to wiki you can build native library or you can go ahead without building the native library. I suggest for windows user to go with without building the native library.
If you have read wiki then in "without building the native library" section last line is like
"To get the .so files, download latest nightly build from nightly
build website and unpack the apk file (apk files are just zip files).
Then get lib/ARCH/.so files and copy it into CSipSimple
libs/ARCH/.so"
I have to clarify one important thing about that:
First get .apk file of csipsimple. The version of .apk file must same to download version of your csipsimple source code..
Here, you can see the source code version. Download the same version .apk and do further as described in wiki.
SipDroid supports only one line at all times. This means you cannot have conference calls. So to the question:
If I make multiple call to the same phone using SIP is there anyway to
handle all calls at a same time?
Nope, you cannot handle simultaneous calls at the same time. Fortunately there's another open source SIP Client that supports multiple lines - IMSDroid.
Though you can extend SipDroid to support multiple lines, that's a lot of effort. The main objects you have to pay attention to in order to support multiple lines are:
UserAgent, SipProvider (note that it's designed to support multiplexing/demultiplexing of SIP messages), JAudioLauncher and the Call object.
The bug you're describing with the second call not showing is not something I have witnessed. This could be due to your device setup, or due to customizations performed on the original code...
you can build the csipsimple easily in linux OS... All you have to do is just paste the download source link in linux commanpropmt and for windows you must have latest cygwin software to download or to build native library... Better option is to go for linux OS only...
