Ok, so I inherited a project where our core program is built by another company (built in Java) and I have to build another program around it. Problem is that the Java program has to stay as is and I am only allowed to authenticate through to it and pull the findings once users go through there. I am not even sure what to ask for cause I've never cross authenticated before nor used a WSDL etc...
I am an intermediate/advanced PHP coder and would have rather built the entire thing from the ground up (it would be faster and customizable) but, i can't. this java application needs to stand on its own--maybe in an iFrame--and once our users sign into our site, they need to automatically signed in there so when they click on it from the panel, they perform their actions which mark them complete there. We read their completion and mark them complete on our side (via PHP). Their develops have a WSDL file that supposedly we pass the information and we can read their completion and status stuff. No idea how to use it.
The dev environment is IIS 7 (im more used to linux and unix environments)
Any idea where I should start? How to do this? What questions I should ask their developer for so I can develop the PHP side of things?

I'm using IntelliJ IDEA, I have coded a frame which I want to put into an HTML file so I can run it in my browser, how do I do this now that I cannot use JApplet? I have found this documentation: http://docs.oracle.com/javase/tutorial/deployment/webstart/deploying.html and this http://docs.oracle.com/javase/tutorial/deployment/webstart/deploying.html but I am new to programming and find this difficult to follow. I don't know for instance how I would go about putting my class files and the image that I used in a separate directory nor do I know how I go about signing my application so that it will run in a browser.
I want to put into an HTML file so I can run it in my browser,
You can use the Desktop class. This class allows you to access default applications from your desktop.
Read the section from the Swing tutorial o How to Integrate With the Desktop class for more information and working examples.
See Java Plugin support deprecated and Moving to a Plugin-Free Web.
Note that is one of my 'copy/paste comments' that does not explicitly mention JFrame based apps., however the links are still relevant in that Oracle & browser makers would not be phasing out support for applets if they wanted programmers to keep trying to shove rich client apps (e.g. Swing GUIs) into thin client web pages.
OTOH you can offer a JFrame (or a JApplet) to be launched from a link in a web page to end up free floating on the desktop of the user by using Java Web Start.
Even then, it is not a simple matter for the programmer or the end user. The programmer needs to ensure the app is digitally signed using a code signing certificate issued by a CA (usually they are expensive). The end user used to just be able to click the link, 'OK' the prompts produced by the Java virtual machine, and see the app appear on-screen. But now most browsers will download the launch file to the local file system rather than directly hand it to the JVM to be launched. So the user faces an extra step in explicitly finding the downloaded launch file and double clicking it.
This is all due to security concerns related to bugs in the plug-ins that run things in web pages. So if you were to find a way around all these hoops, please let us know. It is a security bug that requires urgent fixing.
I hope this is the right place to post this question. The web applications stack exchange did not look suitable based on the other questions asked on there so I guessed this might be the best place to put this question.
I have a java eclipse project that works as I would like it which takes in an image locally from the adjacent file path and performs the required action on this image before returning a double value at the end after all the calculations. To do these calculations I use the OpenCV library which is essential to the core functionality of the application.
The issue I am having is to deploy this application so that the the application when it receives a request will take in an image (preferably as a .jpg but this can be changed if absolutely essential) and then after the application has carried out the required task send back the resulting number. In future this will be sent and received by an Android app which will just take the photo, compress it and send it away before receiving and displaying the answer but for now I'm just trying to get my project onto an accessible server.
I have tried to use Heroku and followed their tutorials and instructions which encourages the use of Maven but I could not properly insert the dependencies for my project as it used an external jar. I spent a lot of time checking through the various solutions online to this issue but a lot of them felt like workarounds which only worked in some cases and none were working for me. I am open to using this again if there is an elegant solution that is simple to follow.
The main sections of this question that I am asking is for the simplest way to take my working eclipse project which uses an external library, modify it to take in an image via server request and then send back a number result. I also would like a suggestion as to which cloud-based service would be suitable for this project and allow me simply to put my code on their service and allow a test user to run this code whenever I want with reasonable availability.
Sorry for the long-winded explanation and I hope I have provided enough information. I have been trying to work out how to do these things with the help of tutorials and suggestions for a few weeks now but have no previous experience with making a web server as everything I have created has been a local program.
Thanks for your help and suggestions
I am developing an e-commerce web application, and in that ads from other giants pop up. I figured out that this is done by PriceFountain, which is actually a spyware. I found the steps to remove that from my laptop. more found here.
but the problem is my clients can also have this adware. I want to programmatically do following or either of them, on the client side:: (and if it is not possible at least inform the user to do so)
If, PriceFountain is present, uninstall it from their system. If it is an add-on, remove that.
Activate the pop-up blocker (deactivation can be achieved through javascript and jquery). But I want to activate. My site does not need pop-ups.
Alter the registry of user for the contents of PriceFountain.
I know this is somewhat an unethical hack, but can this be achieved and if so, how?
More of that, it is just my curiosity can we affect client site settings.?
You used to be able to do that (with jscript/vbscript) in IE if and only if the user added your site to his trusted sites (and allowed pretty much everywhere there), or if it was the intranet-site with relaxed permissions.
Back in the old day's I had such a thing for the intranet-help-site where users could browse through the faq and click on the 'execute solution' button for the common 'problems' (previously solved and added to DB).
For rather obvious security-reasons this is no longer the case (although one can still pull some stuff in legacy IE environments).
The point is: you can't do this on other browsers then IE (unless maybe you'd develop separate plug-ins for them and ask your users to install something that will essentially give you access to their whole machine). Realize that effectively what you are asking for is a way to fully control the user's machine. Would you install such a browser (on your parents pc)?
The best course of action would be to face-up, inform your users on your main-website (enter-page) that something bad spread throughout an ad-network and guide them through the steps (that you already found) necessary to relieve them from their problem.
Even if what you asked was possible, you'd still need the user's cooperation somewhere along the way, even if you'd were to write an application for this that the users could download and run (administrative/elevated)..
Good Luck!
EDIT: for the registry you might try something with the answers in this question: read/write to Windows Registry using Java
Still, you'd still need the user's co-operation.
I have a Google App Engine Application, and as part of that Application I have my standard HTML pages, Home, ContactUs, Testimonials, Pricing ETC ETC, when users click on "login" or go to a specific URL eg (www.diarybooker.com/demo) it loads the actual application.
All these standard HTML files are fairly static files though, with analytics and SEO etc in them, however in order to update these currently I need to release a new version of my application every time.
Can anyone offer any advice as to how I can JUST update the HTML without having to release a new version of my application (especially if I am in the middle of a development cycle and don't want to branch just to update a contact number or fix an SEO issue etc)
It is entirely possible that I am actually using the system incorrectly and that I should be re-wiring things better/differently, but I cant find any information about how this SHOULD be setup, and Im not even sure what to search for either, so if anyone can at least point me in the direction of some information on this, I would be very greatful!!
By way of an alternative example, I have a friend who is running www.wineathome.org.uk and if you click on "attend a tasting" it moves off into http://wineathomeuk.appspot.com. Clearly this is not very clean and is also not the way to make it work, I could embed the application in an iframe, but is that really the way to go?!
You have your application code in source control, right? I'd suggest that you create a deployment directory and clone into it the version of the application that you want to have running on AppEngine. Then, copy into the deployment directory the versions of the HTML files that you want updated. Deploy away.
That is the only strategy that's going to work for you. The GAE deployment tool only deals with your application as a whole.
Looks like you have a couple of issues going on.
On the first issue as #AdamCrossland states you can use source control. I use git and create branches for my application at different versions. If you do that you can merge your updated HTML back into an older branch then update your application from that branch. That way your only changing the HTML files and leaving the application in it's current state. App Engine deploy is intelligent and will only upload the modified files. Doing this from Eclipse is a bit more difficult than from the CLI IMO, but YMMV.
The other issue of a friend clicking on attend a tasting routing the url to appspot is a bit harder to deal with unless some code is provided. I would think it is because the code is doing a redirect to a hard coded URL. I have several application mapped to a domains and none of them route to appspot unless I forced it to in order to use some functionality like HTTPS which only works on appspot.com. I personally try to avoid iframes it opens up an avenue for exploits.
This question might be very basic.
Till now I thought a command to print a webpage can only be initiated at the client side.
(window.print when using javascript)
But I came across http://juixe.com/techknow/index.php/2008/01/17/print-a-pdf-document-in-java/ which states about printing using Java. I think this seems to be related to some desktop client and the same may not be possible in a web client. Can anyone confirm and explain this?
You can't execute server side code on the client, so the only way to do it in browser is through javascript or using plugins/flash/java applets.
You could print using java, but for that java needs to run on the client.
A website can ask the browser to open its print dialog (Google Maps does this on the "print directions" page, for example), but it can't actually force the browser to print anything. (If it could, you can be sure that advertisers would use it to print ads on your printer.)
A Java application running locally with sufficient permissions can print, just like any other desktop application. That has nothing to do with web pages.
Don't confuse Java and JavaScript. When trying to use Java within a browser, you'd have to look into using applets. A Java applet could definitely be used to do the kind of work you'd normally have a rich client do from within a browser.
Java applets could also receive events sent out from a server via sockets or some other mechanism, although I'm not certain if security constraints would allow it. Also seems a bit of a roundabout way to do things.
Remember that web browsing is a client-side-driven affair. There's some push models in certain infrastructures (I believe it's possible using JavaServer Faces). But those are probably just a sort of polling mechanism initiated by the client that is abstracted away to look like a server-side push.
