Document style Problem

Question

We have three issues when trying to implement a document-style service. I will
document them all but I'd suggest you go through them all before attempting to
answer any of them.
We are trying to implement a service that has the following signature:
public void echoDom(Document doc)
We want the delivery of our message to be of style ("document"). Therefore, we
modified our servicegen entry to include the style="document" under the service.
It looks like the following:
<servicegen
destEar="${appDir}/dom.ear"
warName="dom.war">
<service
javaClassComponents="examples.dom.EchoDom"
targetNamespace="http://examples.org"
serviceName="dom"
serviceURI="/EchoDomService"
     generateTypes="True"
expandMethods="True"
style="document">
<client
packageName="examples.dom"
clientJarName="client.jar"
/>
</service>
<classpath>
<pathelement path="${temp_dir}"/>
<pathelement path="${java.class.path}"/>
</classpath>
</servicegen>
1. FIRST PROBLEM:
The first problem we're having is that it does not compile with the combination
of our signature being of type void (as shown above) and the style="document"
in build.xml.
The error is the following:
[servicegen] Generating service "dom" ...
[servicegen] Generating XML types and serializers from java classes (examples.do
m.EchoDom) ...
[servicegen] weblogic.utils.AssertionError: ***** ASSERTION FAILED *****[  void:

2. SECOND PROBLEM
If we change the signature to become:
public Document echoDom(Document doc)
then the build works but when we try to test our service, it gives us the following:
[java] java.rmi.RemoteException: web service invoke failed; nested exceptio
n is:
[java] javax.xml.soap.SOAPException: failed to serialize xml:weblogic.
xml.schema.binding.SerializationException: type mapping lookup failure on class=

[java] deser: weblogic.xml.schema.binding.internal.builtin.XSDAnyCodec@
3. THIRD PROBLEM:
Now, when we revert back to style="rpc" and everything works fine and dandy (although
not as we want it because, as I mentioned above, we want a void signature and
a document style), we get the following added tag around our body content, which
we did not add ourselves, nor are we sure yet why it shows up:
We pass it the following argument:
<those dummy="hi">
<this xmlns="mynamespace">
<f:that xmlns:f="yournamespace">
<or> a lot of random < </or>
<f:the>
</f:the>
<f:other> foo bar blaz</f:other>
</f:that>
</this>
</those>
We get the following (notice the <document> tag around it):
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:Body>
<m:echoDom xmlns:m="http://examples.org"
env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<document>
<those dummy="hi">
<this xmlns="mynamespace">
<f:that xmlns:f="yournamespace">
<or> a lot of random < </or>
<f:the>
</f:the>
<f:other> foo bar blaz</f:other>
</f:that>
</this>
</those>
</document>
</m:echoDom>
</env:Body>
</env:Envelope>
4. PROBLEM FOUR (just remembered this one):
If we use the standard test page (provided with WLS), with (3) above, it chops
off the "those" and it still wraps it within this new <document> element as show
below:
<!--REQUEST.................-->
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:Header>
</env:Header>
<env:Body>
<m:echoDom xmlns:m="http://examples.org"
env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<document>
<this xmlns="mynamespace">
<f:that xmlns:f="yournamespace">
<or> a lot of random < </or>
<f:the>
</f:the>
<f:other> foo bar blaz</f:other>
</f:that>
</this>
</document>
</m:echoDom>
</env:Body>
</env:Envelope>
We're not so worried about the fourth because it seems like a bug but the first
three (especially the first) are most important. Any ideas would be appreciated.
Thanks

Answer 1

Ok I tried it out, DOM with document style web
service is not working in WLS 7.0.2. I filed
CR104719. Please contact support with this case
number to get a patch.
Sorry for the trouble.

Quick question, before i try this out.
Which version of WLS? SP?
