I'm using IntelliJ IDEA Community 13. Everything compiles nicely but when i go to run the code i get the error:
Exception in thread "main" java.lang.ClassNotFoundException: com.helljogl.OneTriangleSwingGLJPanel

I have OpenGL and Java experience, but for some reason this is giving me a huge headache.
I've been at it for hours and have seen similar problems, but found no solutions...
Any ideas?
Rather than adding the dependencies to the project through the IDE, use maven (or Gradle). There's no need to manually download the jogl jar files and mess around with your classpath. See How to set up IntelliJIdea for development using JOGL on Linux and Windows?
After so many Installation Attempts I had jogl.jars all over the place. After cleaning up my environment everything is going smoothly!

I know almost nothing about Java so please take it easy on me. I'm using this plugin, which I've had working nicely for a few days on my Mac (following the repo's very simple instructions below), but when I took it to an Ubuntu instance I got the following error:

Anyone have thoughts on what is going wrong?
Installation and usage instructions:
1. git clone https://github.com/antonydeepak/ResumeParser.git
2. cd ResumeParser/ResumeTransducer
3. export GATE_HOME="..\GATEFiles"
Paths are case sensitive in Ubuntu, GATEFiles is different from GATEFILES. Since gate.SimpleAnnotation is in gate.jar, I bet that your classpath should be:
-cp 'bin/:../GATEFiles/lib/:../GATEFiles/bin/gate.jar:lib/*'
Disclaimer: I haven't used this plugin, I don't know if the other parts of the classpath are correct.
In general, you can "debug" by trying
ls ../GATEFiles/bin/
to see if there is a gate.jar file.
It's hard to know, but most likely the class it cannot find is in the gate.jar file, and it is either not on the new machine, or is not in the correct place on the new machine.
To expand slightly: Classes are found in a couple of places, but you specify a gate.jar on the classpath of the command line (that's what the -cp designates), so I'm guessing it's there. Since java can't find it, I'm guessing further that the necessary jar file is not where it needs to be for the Java runtime to find it.
For Linux and OSX use '/' and ':' , try this call .. it worked for me
java -cp './bin/*:../GATEFiles/lib/*:../GATEFiles/bin/gate.jar:./lib/*' code4goal.antony.resumeparser.ResumeParserProgram cv.pdf cv.json
I have a large java application running on a Red Hat Enterprise Linux server. This application has around 100 jars. On most RHEL systems the application runs fine, however, on certain RHEL systems (all RHEL versions are the same) I get a NoClassDefFoundError on startup (before my application gets a chance to do anything). If I rename the JAR file which contains the class (e.g. com-test-1.3.4.jar -> com-test-1.3.4-2.jar) everything starts up great even though the renameing doesn't change the order of the JAR in my directory listing. If I add the JAR file to the beginning of the classpath it works great. On other systems with the exact same OS/classpath/java/jars it works great. If I try to run the class that java says is missing (before renaming), java reports that the class does not have a main method so I know the class itself is loadable/findable. I have tried the latest version of Java 1.7 with no luck. The classpath is specified using the wildcard operator (e.g. CLASSPATH=/home/test/*).
The actual exception:

Can any one give me a solution for the above error?
Please check if you have httpcore jar. I got rid of this error, after adding httpcore-4.2.jar to my lib.
It's difficult to pinpoint the exact reason why your application raises this exception, but a few common pointers that might help you.
The exception is raised when you are using a class in your code that isn't available when it runs. In this case, it seems you are unable to use org.apache.http.protocol.HttpContext. Most likely, you created an application that does include the Amazon AWS jar, but lacks the Apache HTTPClient jar.
If you used gradle/maven to create your application, include it in your dependencies. It it's a plain Java program, ensure the required JARs are available in your classpath (e.g. the same place as you currently have the Amazon jar located).
When I try to simulate my little project, I decided to use jme3 library and browsed the jar file through Configure-> JDK Profiles-> Add Archieve-> JME3-core.jar and ran the project sample code. The code was written in a website and I got the exception as:
Mar 25, 2014 10:53:44 AM com.jme3.system.JmeSystem checkDelegate

Process completed.
Is the problem about the native libraries kind of issue which is also need to be dealt with J3D libraries? I mean, do I need to follow some instructions about installing and importing JME3 libraries? If so, can anyone tell me the instructions or where to download the correct .jar file?
find a similar discussion here ..this might be relevant ...

Now what I have done so far:
I created a libs folder in my project folder and added the Jsoup.jar there. Then in eclipse I click properties, add external Jar and added it. I see the referenced library.
But the issue still persist. I dont get compilation errors. So this is a runtime issue. Appreciate the help.
Edit:
I have found the following
If I compile using
javac -classpath /path/to/jsoup.jar myclass.java
and then
java -classpath /path/to/jsoup.jar myclass
It runs perfect.
Now. This is not working for me because I am going to use my application on a computer that does not have Jsoup. So how to I resolve this runtime issue?
Go to Run configurations... menu and check classpath for Run task. It looks like you add library for Compilation step, but it doesn't set at Run step.
Edit (after comment)
I dove into the issue and found that this dependency is needed for application container. So you just need to add this library to classpath of your app server. If you use Tomcat, just put the library to the %CATALINA_HOME%\lib directory.
