UnsupportedClassVersionError

Hi all,Im trying to use a Java Class file located on the file system, the notes.ini var “JavaUserClasses” specifies the full path to the .jar file.

Using LS2J I call the jsession.getclass( ClassName§ ) resulting in

LS2J Error: Threw java.lang.UnsupportedClassVersionError: ( Unsupported major.minor version 49.0 )

My current JRE is 1.5, when switching to 1.4 it generates the same error except the version #:

( Unsupported major.minor version 48.0 )

There’s another problem: if the “JavaUserClasses” specifies only the directory where the .jar file is located the

CLassNotFoundException will be raised ?!

The JRE that comes with Notes 6.5.4 is 1.3.1. In my experience the “javauserclasses” environment variable should specify the full path (just like a classpath variable) – not just the directory. For example:JavaUserClasses=c:\jars\xml-apis.jar;c:\jars\crimson.jar;

And you’ll need to restart after changing your ini file. Incidentally, you may want ot have a look at this → response too.
