APT request beans: WS parameter names "arg0, arg1" instead of names
from src code

Hi all,
I'm trying to integrate the JAX-WS 2.1.2 framework starting from java.
I've managed to generate all required artifacts, created and
successfully deployed the .war archive. Everything works just fine, BUT
the parameter names of the generated WS request beans get lost ans I get
arg0, arg1 instead.
I was using the APT tool instead of Wsgen only to ensure the parameter
names will be kept. The JAX-WS documentation says "... it is recommended
that the portable artifacts be generated from source using apt. This
because the JAX-WS tools will then have full access to the source code
and will be able to utilize parameter names that are otherwise not
available through the Java reflection APIs".
If I use the @WebParam annotation, the name of the web service
parameters is taken, but since I have ca. 400 existing web services, I
just want apt to get the parameter names from source code.
Do I have to add special options to my Apt Ant task?
<apt fork="true" debug="true" verbose="${verbose}"
destdir="${build.classes.home}" sourcedestdir="${build.src.home}"
sourcepath="${src.dir}" nocompile="true">
<classpath>
<path refid="project.path" />
<pathelement location="${build.src.home}" />
</classpath>
<option key="r" value="${build.src.home}" />
<source dir="${src.dir}">
<include name="**/*.java" />
</source>
</apt>
Does someone have any ideas?
Many thanks in advance!
Lena

IIRC, this is because the spec required semantics that the absence of @WebParam defaults to "arg0", "arg1"... and etc. Otherwise we can't guarantee the consistent semantics.
We do regret the fact that default parameter names are poorly chosen, and we are working with the JavSE team to improve the situation, but in the mean time, I don't think we can make you happy in a portable way.
What we might be able to do, instead, is to have the vendor extension of Metro where we capture the parameter names from APT (in a non-portable way) and use it at the runtime. If you like that, please consider filing an issue on http://metro.dev.java.net/issues/

Thanks for your reply!
I ended up writing a small parser which parses the specified java class
file and adds the @WebParam(name="<parameterName>") annotation to every
parameter of public methods.This way I don't have to alter ca. 400 WS
manually.
Thanks again for your help!

Can you upload this parser somewhere ?

Sorry, I've apparently missed your message. I'll attach the source anyway - perhaps it can be useful for someone else...
The parser is VERY quick&dirty, so please don't stone me for the poor error handling and very basic processing.
