Question

Is Sun/Oracle JDK required to build WSO2 4.1.x?

I tried building with OpenJDK, but ran into the following issue:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile 
  (default-compile) on project axis2-transport-testkit: Compilation failure: Compilation failure:
[ERROR] ... carbon_kernel_4.1.0/dependencies/transports/1.1.0-wso2v8/modules/testkit/
  src/main/java/org/apache/axis2/transport/testkit/doclet/ResourceInfoDoclet.java:[27,22] 
  error: package com.sun.javadoc does not exist

Answer 1

Yes, Oracle JDK is required to build Carbon.

Currently Open JDK is not recommended.

Please make sure to use Oracle JDK 1.6 for building Carbon.

You can use Oracle JRE 1.7 for running WSO2 products, but there are known issues with compiling the source code with Java 7.

See http://docs.wso2.org/wiki/display/Carbon410/Installation+Prerequisites for additional info.
