I got the following error message when trying to build using ant.

Unable to load default ProjectHelper due to java.lang.UnsupportedClassVersionError: org/xml/sax/SAXException (Unsupported major.minor version 49.0

Does anybody know what's wrong? It was working fine with my build.xml. But now got this error.

My ant version: 1.6.2
My JDK: 1.3.1

Thanks in advance for your help.

Unsupported major.minor version 49.0 sounds like a java version mismatch somewhere in your build.

Some class you are trying to use was compiled with Tiger.
