Friends,

We are using Retrotranslator to translate an application developed with JDK 1.6 to run on Java 1.4 run time environment.

Translation working good with the frontend application (Struts2, JDom2...etc). But, it is failing for our EJB class with the following exception...

Development Java Environment : jdk1.6.0_31
Compilation Java Version : Java 1.6
Run Time JDK : jdk1.4.2_04
RetroTranslator : net.sf.retrotranslator.transformer.RetrotranslatorTask @ retrotranslator-transformer-1.2.9.jar


application.xml (on EAR file)



ejb-jar.xml


ant build task for translation



Exception:

The error message tells you the jar files aren't using Java 1.4. There are a few reasons this could be. The most likely one is that you aren't using the "after" version of the jars. I notice that the documented example uses a different directory for the source jars and destination jars. Can you try that? And look at the generate file sizes to make sure they are in fact different.

Thanks Jeanne Boyarsky.

It worked. Strangly, it is working on Eclipse too now. Weird.
