title: How to troubleshoot Informatica Java Transformation compilation error?
body: <p>I have an issue with my Informatica PowerCenter Designer Java Transformation. Version 10.1.0</p>
  
  <p>I have all the required jar files added to the Classpath. But when I compile it says: JTXPartitionDriverImplGen.java:12M</p>
  
  <p>When I click on Apply, it says: Compilation of Java code failed - transformation invalid.</p>
  
  <p>When I validate the mapping it says: Byte code for the transformation is not in the repository. Java transformation is invalid.</p>
  
  <p>We tried the same exact steps on my co-workers machine and it compiled successfully.</p>
  
  <p>I'm running out of ideas on how to fix this. Google search hasn't helped. I've tried different versions of JDK and JRE. Finally I decided to re-install this version of Informatica Designer and it gave me the same error.</p>
  
  <p>I do have another (older) version of PowerCenter Designer that I need for a different project. Could conflicting versions be causing this?</p>
  
  <p>Please provide any ideas if you can. Thank you.</p>
