The stack trace points to this line in the src code

major version number of the class file for org.apache.axis2.description.AxisService.class is set to Java SE 5.0 = 49 (0x31 hex),

Hello Robert

Thnx for your help

Unfornatelly i’m force to use java 1.5 execution enviroment so 1.8 is not posible

Its there a way to make axis2 v 1.7.X compatible with JRE 1.5

Sorry but my english its not very good! I hope you understand me


According to the docs, 1.5 is supported by axis2.

https://axis.apache.org/axis2/java/core/docs/installationguide.html#requirements
Are you using the same compiler version to build your class files, as the JDK version running your application container (tomcat) etc? You should use the same major JDK version (1.5 should be ok) for compiling and running the application.
Its hard to help further without a stack trace.
