I want to create a web service and using Apache CXF 2.7.12. My jdk version is 1.8.0_20. While generating WSDL file in eclipse got this exception.

java.lang.NullPointerException

I have no idea about the problem related with Java6Compiler.

what's your eclipse compile settings? is eclipse set to use 1.8? – djb
Yes 1.8 I have already only installed jdk 1.8. And set it to environment variables. – Ugur Artun
Also add it to the JDK compliance settings in your eclipse. Java Compiler in your properties... – Mathias G.

I solved problem after selecting JavaSE-1.8 execution environment in eclipse. It shows compatible jars jre1.8.0_20[perfect match]
