Hi,
When I use the axis wsdl2java tool I get this error..
java.lang.NullPointerException
at org.apache.axis.wsdl.toJava.JavaBeanHelperWriter.getAsFieldName(JavaBeanHelperWriter.java:435)
at org.apache.axis.wsdl.toJava.JavaBeanHelperWriter.writeMetaData(JavaBeanHelperWriter.java:325)

at org.apache.axis.wsdl.gen.Parser$WSDLRunnable.run(Parser.java:362)

Could some body please explain me why it occurs..
I am new to web services so I am not sure what is wrong with the wsdl..

Thanks,

As you have experienced, the Axis 1.x WSDL2Java exceptions aren't particularly helpful for diagnosing problems in an WSDL. Diagnosing the problem in the WSDL without the WSDL is a bit difficult...

This can happen if it is missing a jar file , I actually forgot the name....

In some cases i found that even though it gives the exception ,it actually creates the client , you can find the class files in the .deployables

Create a jar of all the class files and you can use it in your application.

jar -cvf somename.jar

Give a shot and let me know
