java.lang.UnsupportedClassVersionError

[former_member466998]

Dear Friends,

I am trying to deploy my WD applications thru NWDI on to Portal and i am faced with the following error

java.lang.UnsupportedClassVersionError: com/nissan/nesap/cdd/mesmng/wdp/InternalMessageManagerComp (Unsupported major.minor version 49.0)

at java.lang.ClassLoader.defineClass0(Native Method)

at java.lang.ClassLoader.defineClass(ClassLoader.java:539)

at com.sap.engine.services.deploy.server.ApplicationLoader.defineClassWithInterception(ApplicationLoader.java:168)

at com.sap.engine.services.deploy.server.ApplicationLoader.loadLocalClass(ApplicationLoader.java:140)

at com.sap.engine.frame.core.load.ResourceLoader.loadClass(ResourceLoader.java:127

Currently I am using NWDS 7.0.0 and JDK 1.4.2_16 and the portal server is on EP 7.0.0 SP15 with JDK 1.4.2_12 .Is this causing the class compatibility exception? Please indicate what version of Java should be used to maintain compatibility and what else factors need to be taken care of??

THanks and regards
