Ignore some types of error when invoke JBossWS JAX-WS command to generate web service code

when using wsconsume.sh command to generate jax-ws code, it usually reports errors something like:
[ERROR] com.sun.tools.javac.Main is not available in the classpath, requires Suns JDK version 5.0 or latter.
unknown location

compilation failed, errors should have been reported
Failed to invoke WsImport
java.lang.IllegalStateException: WsImport invocation failed. Try the verbose switch for more information

although it has errors, the jax-ws skeleton code has been generated, so the error should be ignored by JBoss Tools
so that the generating web service of JBossWS process can go on.
