I use JBDS to create a "web service" based on a POJO. It generates some artifacts included some java source files.
In the file named XXXResponse.java, there's some error code like:

@XmlElement(namespace = "", name = "return")
private String return;
public String getReturn()

public void setReturn(String return1)

"return" is a java key word, and can not be used as variable. This has been verified by
a) JBDS generation of the webservice (Bottom-Up)
b) wsprovide.sh (myself) -k
c) wsprovide.bat (customer) by running JBDS on Windows

The class itself when decompiled seems to have correctly the name to "_return"

Hence, there seems to be an error in wsprovide tool creating the .java files (perhaps the wsdl as well)
