forms_rt.jar compaibility with java 1.3

Please try use it in ANT script:

    
      
      
    
  
  
    
      
      
      
      
      
    
  
]]>

You must have %IDEA_HOME%/plugins/uiDesigner/javac2.jar or
%IDEA_HOME%/plugins/uiDesigner/lib/uiDesigner.jar in ANT classpath.

Please, try it and send results, if you can.

Thanks!

Is it possible to run a GUI built with IDEA on java 1.3?
I've tried this and get an UnsupportedClassVersionError (possibly coming

from forms_rt.jar?).

Thanks for the info, however I believe that even javac2.jar is not compatible with 1.3.

To recreate this, I just put javac2.jar in a new folder with the following build.xml file, set JAVA_HOME to 1.3.1 and ran "ant". It produced the exception below. I also tried using uiDesigner.jar with the same results.

BTW, I'm using the jars from build #957, on Windows with J2SE 1.3.1.

I think you right...
And Javac2 must be recompiled on JDK 1.3, or even 1.2

Thanks!
