I'm trying to get some server side stuff going for my GWT project. As a test I tried to add in a com.sun.jmx.snmp.SnmpOid object which isn't supported by GWT run-time into my GreetingServiceImpl.java (a file that gets generated with every GWT project), but it's still saying that it's not supported.
I did the RPC GWT tutorial and when I copied the same code into that projects GreetingServiceImpl it worked fine.
I feel that I'm missing a reference or a line in an XML file. I've compared both projects thoroughly but couldn't find any discrepancies.
Any help would be appreciated.
Exact Error: com.sun.jmx.snmp.SnmpOid is not supported by Google App Engine's Java runtime environment
Please check the source path in your .gwt.xml file. It should say something like:
<source path='client' />
<source path='shared' />
Make sure, that your GreetingServiceImpl isn't in the source path.
If that's not the problem, please provide the exact error message you get.
Update
The error message you provided now, indicates that the class isn't supported by AppEngine - that's not the same as "not supported by GWT". If you don't need AppEngine, remove AppEngine support from your project (Project > Properties > Google > AppEngine > Use App Engine).

I'm trying to build soot.
I've downloaded the source code of JastAddExtensions using svn co https://svn.sable.mcgill.ca/abc/trunk/JastAddExtensions/, checked out the code of Soot using
git remote add soot https://github.com/Sable/soot.git
git pull soot develop.
Then I tried to build Soot using Ant and got following error message:
D:\dev\ro-01\soot\build.xml:102: The following error occurred while executing this line:
D:\dev\ro-01\JastAddExtensions\SootJastAddJ\build.xml:18: taskdef class JFlex.anttask.JFlexTask cannot be found
using the classloader AntClassLoader[]
How can I fix this error? Where can I download a version of code of JastAddExtensions\SootJastAddJ, which is compatible with current version of Soot?
You will get help faster on the Soot mailing list. You do not need do build the JastAdd part of Soot. It's pre-built in the directory "generated".
Check out:
http://jflex.de/jflex_anttask.html
Simple answer: You probably haven’t copied the JFlex jar to ant’s library folder/directory.
If that doesn’t straighten you out… More complex solution: Find the soot Ant file, probably in the project root directory as build.xml.
Then find a task definition named “jflex” that probably looks like this:
<taskdef classname="jflex.anttask.JFlexTask" name="jflex" />
Change it to something like this:
<taskdef
name="jflex"
classname="jflex.anttask.JFlexTask"
classpath="${compiler_tools_path}${jflex_jar_name}"
/>
Up near the beginning, with the other properties, create a new one with the location of a directory/folder you create and copy the latest JFlex jar to:
<property
name="compiler_tools_path"
value="/Library/CompilerTools/"
/>
This is an appropriate place to create a directory/folder to store this on a Mac. Windows and Unix, anywhere externally installed jars are stored.
<property
name="jflex_jar_name"
value="jflex-1.5.1.jar"
/>
An example of a recent JFlex jar build. Check out:

I hope this was helpful.

I took a look at build.xml in the soot repository. The problem is with the target jastadd. The JustAdd compiler uses Beaver as its parser generator, which also requires JFlex as it's scanner generator for handling .flex files.
Just follow my simple solution mentioned previously. Make sure you rename the jflex-1.5.1.jar file that you copy to Ant's lib directory to "JFlex.jar" It's all in the document I gave you that first link to.
I'm answering this problem so late because I only just came across a similar problem with getting ant files to work with JFlex in Eclipse projects.

I get the following error in Endeca:
com.endeca.navigation.ENEException: Navigation Engine not able to process
request `http://myhost:15000/search?terms=remote&rank=0&offset=0&irversion=601`
My MDEX version is 6.3.0
The referenced jar files in my app is:
endeca_navigation.jar : Specification-IR-Version: 6.3.0 (Read from MANIFEST file)
endeca_logging.jar: Specification-Version: 6.1.2 (Read from MANIFEST file)
Even with these referenced jars, why is the request parameter still irversion=601?
I'm using java 1.5 and building my app in eclipse. At first, it was referencing older jar files (601), but i removed those completely and replaced them with the newer jar files listed above. I've rebuilt my app and I still see the parameter irversion=601. I've been trying to find out what the issue is for a few hours, but i'm having no luck.
Any ideas?
If nothing else I think that you need an N=0 parameter for you request to work.
Also if you are using an application server like Weblogic to run you app, it has a tendency of caching referenced jars which may have to be cleared for it to pick up the new versions of the jars.
Finally if all else fails there is a --back_compat 601 parameter on your dgraph which indicated the accepatble navigation.jar versions. You can use this parameter to determine if the issue is the jar version or something else in between.
Good Luck
Additionally to Wiszh's response, it is useful to take a look at the dgraph request query logs (located in /logs/dgraph/Dgraphxx/Dgraphxx.log and .reqlog) which will show a more specific error and the query that caused it.
Do your jars match the version of Endeca server you are querying?
This issue is due to an old navigation api jar in your class path
Check the ToolsAndFrameworks\version\assembler\lib to get the correct version of navigation api jar. That should fix this issue.
correct jar path fixed the issue for me

I am currently developing an Android app using cordova 2.0. Obviously the plugins.xml has been depreciated and everything is now housed in config.xml. I was just wondering if anyone has managed to get the Phonegap Screenshot plugin working in Eclipse and Cordova 2.0 working on android.
Plugin can be found:
https://github.com/josemando/phonegap-plugins/tree/master/Android/Screenshot
I have added:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
to my Android manifest xml. And made sure that:
<plugin name="Screenshot" value="org.apache.cordova.Screenshot"/>
is added to my config.xml (that now contains all plugin information from plugin.xml)
Screenshot.js is added to the directory:
assets/www/js/
However I am unsure where exactly to place the Screenshot.java file. The example has it in:
src / org / apache / cordova /
However as I did not have this directory I simply placed it in:
src/uk.co..appname1.appname2/
When I did this however it produced errors, the first one being:
The declared package "org.apache.cordova" does not match the expected package "uk.co.mysitename.appname1.appname2" Screenshot.java /Project Name/src/uk/co/mysitename/appname1/appname2line 8 Java Problem
This refers to this line in the Screenshot.js:
package org.apache.cordova;
The two suggested actions to fix this are to:
Move 'Screenshot.java' to package 'org.apache.cordova' (this directory doesn't exsist atm)
Or change package directory to 'uk.co.mysitename.appname1.appname2'
The second error says:
The method run() of type new Runnable(){} must override a superclass method
The suggested action for this being to "remove '#override' annotation"
I have tried to do every possible combination of these however I cannot seem to make progress and get it all to link up. Usually because it thinks that CordovaRef isn't referenced. I am unsure if the plugin even works on Cordova 2.0.0. I have some experience with Phonegap/Cordova but only in ios with Xcode and Objective C plugins. I am new to Java, Eclipse and Android. Any help or clarification on any of these matters would be greatly appreciated.

I can't get Guava to work with GWT. I'm using Eclipse, I've added both guava-11.0.2.jar and guava-gwt-11.0.2.jar to my class path, inherited the module com.google.common.collect.Collect in my gwt.xml file but still can't get it working.
It compiles but when I run it a lot of error appear. Many of them refering to unresolvable annotation javax.annotation.Nullable
I tried adding jsr305.jar to my class path but nothing chanded.
Also some errors appear depending on which version of Guava I include (tried with 11.0.2, 11.0.1, 10.0.1) and if I include or not the jsr305.jar
Some examples of these error are:
The type PersonActivity.PersonFilterPredicate must implement the inherited abstract method Predicate<PersonRoleProxy>.apply(Object)
The method compare(T, T) in the type Ordering<T> is not applicable for the arguments (Object, Object)
Which is quite strange because the code compiles and these kind of error should appear at compile time.
We have been embarrassingly unable to figure out the solution to the #Nullable problem, which we believe to be a GWT problem. You can follow along at http://code.google.com/p/guava-libraries/issues/detail?id=776 We're trying to get help from the GWT team, but things have been kind of crazy lately for the people who work on the part of the compiler we're interested in. It does look like you can work around the problem by removing -strict from your GWT compilation arguments, but of course that's a terrible workaround.
Other users' experiences suggest that the weird other errors you're seeing are related to the #Nullable problem, though I haven't seen definitive confirmation. You might also confirm that all your imports are com.google.common.* and not com.google.gwt.thirdparty.guava.common.*
Sorry for all the trouble. This is one of a few major thorns in our side at the moment.
The following workaround works for GWT 2.4.0 with
Guava 14.0 RC1 and
jsr305-1.3.9.jar
Create a file named Annotation.gwt.xml with the following content:
<module>
<source path=""/>
</module>
Within the archive jsr305-1.3.9.jar copy this file into sub-directory javax/annotation.
Add the following line to your applications .gwt.xml file:
<inherits name='javax.annotation.Annotation'/>
I am trying to use emacs and slime to connect to swank to live code using Overtone. I have the whole thing pretty much working, but when i try to run
(ns foo
(:use [overtone.live]
[overtone.inst.synth]))
(definst bar [] (saw 220))
I get the error 'Could not locate overtone/live__inti.class or overtone/live.clj on classpath:' Which i gather basically means that the class files are not where it is looking for them. I am not sure what to do to fix this.
Important note: Slime/Swank/Cake are deprecated means of connecting Overtone and Emacs. Instead, consider using nREPL via Leiningen 2+ and CIDER
it looks like you haven't got the Overtone jar on the classpath. Things to check:
You have overtone-X-Y-X.jar in your project's lib directory
Your project isn't called Overtone (that can cause issues with tools like lein)
Finally, you might want to take a look at this setup video: http://vimeo.com/25190186 which describes the process of getting an Overtone dev environment setup.
Good luck and come join the mailing list and share your thoughts: http://groups.google.com/group/overtone
Have you tried confirming that overtone is in your java classpath?
(System/getProperty "java.class.path")
It's most likely a temporary fix, as I'm just getting my feet wet with clojure and overtone, but I included overtone as a global dependecy in my ~/.cake directory and installed it with:
cake deps --global
Additionally, I'd reccomend updating to the latest version of overtone as it looks like the vimeo link is a few versions behind what is currently reflected on clojars:
