jax-ws-import-fix.md

A class/interface with the same name "x.y.z.class" is already in use. Use a class customization to resolve this conflict.

The issue is usually due to case-sensitivity error, where the same name for element and attribute issue (thru inheritance sometimes).

For case-sensitivity issues you can usexjc argument -XautoNameResolution, maven version is <args><arg>-B-XautoNameResolution</arg></args>.

When using external tools for code generation, specify the argument:

xjc argument -XautoNameResolution

jax-ws-maven-import-fix.md

For maven based projects, pass the -XautoNameResolution to the JAXB compiler .e.g
