Unsupported major.minor version 48.0 problem while running the an telope task- Help needed

Hi All,

I am having  a problem with Antelope task.

This is my ant script:

<project name="Installation" default="sqlrun">

	<target name="sqlrun">
	<taskdef name="var" classname="ise.antelope.tasks.Variable"/>
	<property name="ant.enable.var" value="true"/>
    
	<var name="x" value="6"/>
    <echo>x = ${x}</echo>   <!-- print: 6 -->
    
    <var name="x" value="12"/>
    <echo>x = ${x}</echo>   <!-- print: 12 -->
    
    <var name="x" value="6 + ${x}"/>
    <echo>x = ${x}</echo>   <!-- print: 6 + 12 -->
    
  	
	</target>
</project>

while running the script, error given as

sqlrun:
BUILD FAILED: java.lang.UnsupportedClassVersionError:
ise/antelope/tasks/Variable (Unsupported major.minor version 48.0)
Total time: 370 milliseconds

what could be the problem? How to solve this?

Can any one help me out.

Thanks,
Nagarajan

Alternatively, recompile the tasks using JDK 1.3.

It's telling you that the antelope task was compiled using Java 1.4 and you
are trying to run it with an older version of Java.

Use 1.4 JRE/JDK and the error will go away.
