Java Mapping Runtime Error: Linkage Error


when i try to execute my Java mappping in ESR i ll get an error msg:

LinkageError at JavaMapping.load(): Could not load class: ervMap/ChunkFakturaInfo

java.lang.UnsupportedClassVersionError: (ervMap/ChunkFakturaInfo) bad major version at offset=6

at java.lang.ClassLoader.defineClassImpl(Native Method) at java.lang.ClassLoader.defineClass(


I developed with Eclipse Indigo Release 1 and compiled the mapping with compiler level 1.5 (jdk1.5.0_15, Standard VM) and 1.6 (jre6 Standard VM).

The PI system is 7.01 (Releases NW701_06_REL), Java Runtime environment 1.6.0_29.

Does anybody know how to solve the problem?

    From what I know PI 7.0 is running on Java 1.4.

    Can you try to compile it with 1.4 and redeploy ?
