JUnit Error: Unresolved Compilation Problems Due to Missing WebLogic JAR

java.lang.Error: Unresolved compilation problems:

Facing issue is often hurdle for developer :) :) As you all know, Java Developers Guide always posted the real time issues. This issue I have faced while writing Junit test cases, but its not so easy to fix your development desktop. The below issue normally happens when the class path is missed the related weblogic jar.

I am using weblogic for jaxrpc client calls, and its failing to find the weblogic jar. Below error logs :  

java.lang.Error: Unresolved compilation problems:

How to fix  :- This is very simple, just add the weblogic.jar library jar into your class path. Steps as below,

Right Click on Project => Build Path => Libraries and then add the required jar (In my case I have added weblogic.jar).

Eclipse Main Class Not Found: Troubleshooting Classpath Issues

This is the common issue with Eclipse , even I faced many times . This is not related to Eclipse or any other IDE tool.


This issue occurs when you are trying to run your main() method with respective class, its looking for the exact .class file in the class path.During the execution the .class file is not available in the class path. The best way to resolve this is, add the .class file into class path.

There are many possible diagnosis you can do in your Eclipse for this issue. As per the Eclipse behavior when you are updating the class path (Build Path) , your class is getting compiled that time and the .class file got created. So, Be careful when doing the build path for your project.

Also check your Build Path, if any jar file is missing. Because, its might causes sometime.

In my case I just found the jar file missing in the build path , and I removed the missing jar and added new jar file from other location.Then executed my class with main method and it works. Below screenshot shows my issue.
