Problems with WSDL2Java

[Christian Pöcher]

Hi there,

since I am still very fresh to the area of webservices, I'm not sure, if
my problem is related to a bug in the code gerneration of Axis2 or if I
made an error.

I try to write a simple webservie that adds two integers and gives back
the sum. After writing the WSDL file and and generating code with
WSDL2Java, I notice errors in the code. I tried both Axis2 1.0 and the
nightly build of today. In 1.0 I get an error about newXMLStreamReader()
as described in http://issues.apache.org/jira/browse/AXIS2-760?page=all
and in the nightly I get totally funny code like this:
wrappedParam =
()fromOM(
msgContext.getEnvelope().getBody().getFirstElement(),
.class,
getEnvelopeNamespaces(msgContext.getEnvelope()));

I'd appriciate an explaination and a workaround very much.

I used the following WSDL file:

<?xml version="1.0"?>
<definitions name="mathWS"

targetNamespace="http://chris.math.ut.ee/plus.wsdl"
xmlns:tns="http://chris.math.ut.ee/plus.wsdl"
xmlns:xsd1="http://chris.math.ut.ee/plus.xsd"

<port name="MathWSPort" binding="tns:mathWSSoapBinding">

</port>
</service>

</definitions>

Afterwards, I decided to try the example WSDL file from the spec
(http://www.w3.org/TR/wsdl#_wsdl), which gives an exception with both
versions of Axis2.

Just for the archive: I resolved the problem. It was of course my fault,
although I wished the WSDL2Java tool would do a validity check, before
generating code.

In <types> I defined elements like <element name="sum" type="integer"/>
while in <message> I used a type attribute.
<message name="getSum">
<part name="rightHandSide" type="sum"/>
</message>

I also seem to have referenced an old version of the Schema namespace.
Changing <schema xmlns="http://www.w3.org/2000/10/XMLSchema"> to <schema
xmlns="http://www.w3.org/2001/XMLSchema"> finally helped.

And just for clarity -- the sample WSDL in the WSDL spec is not valid...

Hi,

Add "Web reference" to your project from menu, if you use Visual Studio

Pick one of the C++ SOAP toolkits (Axis for C++, gSOAP, Systinet for
C++, etc) and use the supplied tool to generate a C++ client stub from
your service's WSDL.

Your WSDL doesn't validate - try using one of the many wsdl validators
and that should point you in the right direction. In the w3 case, you
also need to supply the external schema reference.

I still think that the original poster (below) has found an error worth
logging in JIRA. Either Axis should generate a compilable webservice from
his WSDL, or it should emit an error message explaining why it can't. It
appears that neither is happening in this case.

In general, I think errors of that sort should be fixed, so that Axis at
least emits reasonable error messages when people do something wrong.

I'm going to get on a soapbox for a moment, because this is starting to
become a pet peeve of mine. It seems to be pretty common on this mailing
list to have dialogues of the form:

A: When I do <blah>, I get a NullPointerException from WSDL2Java!
B: Your WSDL is broken. Don't do <blah>. Do <blargh> instead.
A: OK. I fixed the WSDL. But now, WSDL2Java produces uncompilable code!
B: I noticed another way that your WSDL is broken. Don't do <foo>. Do <bar>
instead.
A: OK. I fixed that too. Now everything works great. Thanks!

with the implication being that a NullPointerException or producing
uncompilable code is a perfectly valid way for WSDL2Java to tell the user
that something is wrong, and that fixing the user's WSDL is therefore enough
to fix the problem. Thus, the original user's problem is solved with no JIRA
having been created, so that Axis never gets fixed. This means that the next
person who does <blah> hits the same problem, and MAYBE eventually resolves
it by searching the mailing list archive, or maybe just wanders off and
finds another SOAP server with a less user-hostile interface. This is part
of why there is so much traffic and so many confused people on the Axis
mailing lists.

I would like to see more dialogue like the following:
A: When I do <blah>, I get a NullPointerException from WSDL2Java!
B: WSDL2Java should never throw a NullPointerException under any
circumstances. Please file a JIRA. Also, I noticed that your WSDL is broken.
Don't do <blah>. Do <blargh> instead.
A: OK. I filed JIRA #1234. But now, WSDL2Java produces uncompilable code!
B: WSDL2Java should never produce uncompilable code under any circumstances.
Please file a JIRA. Also, I noticed another way that your WSDL is broken.
Don't do <foo>. Do <bar> instead.
A: OK. I filed JIRA #5678. Also, fixing my WSDL as per your suggestion fixed
my problem. Thanks!
C: I fixed JIRA #1234 by having WSDL2Java detect attempts to use <blah>, and
emit an error message suggesting <blargh> instead.
D: I fixed JIRA #5678 by having WSDL2Java detect attempts to use <foo>, and
emit an error message stating that <foo> is not supported.

I'm guilty of this myself a bit -- I have seen some bizarre Axis WSDL2Java
behavior that I haven't reported to JIRA yet because I found a workaround.
In particular, WSDL that isn't WS-I compliant seems to frequently produce
malignant chaos of one sort or another instead of nice, comprehensible error
messages. I'm going to report the bugs that I found when I get a chance. I
encourage others to do likewise.

It seems to me that if WSDL2Java or similar tools EVER fail due to a
NullPointerException, ClassCastException or other RuntimeException, or if
they appear to run but produce uncompilable code, a JIRA should be filed in
every case.

Hi, folks.

I just ran WSDL2Java (from yesterday's nightly build), and generated a bunch
of output files. Now, I am trying to test a client which is written with
those output files. Whenever I try, however, I get the following exception:

I have verified that the generated 'resources' directory is in my classpath.
I have also verified that there exists a subdirectory of it named
schemaorg_apache_xmlbeans/system/s3F178E0A50CC587BC745803A994CE78D. However,
there is no TypeSystemHolder class in that directory (although there are a

I am rather flummoxed as to what to do. Has anybody seen this before?

[robert lazarski]

When you run WSDL2Java with xmlbeans, there will indeed be a
TypeSystemHolder class generated and you have to somehow get that
class into you classpath. From the codegen guide:

http://ws.apache.org/axis2/tools/1_0/CodegenToolReference.html

"An important detail is that an XMLBean class file is also generated
by WSDL2Java, TypeSystemHolder.class. That file is placed into
build/classes by the above ant task and will be needed to compile the
generated sources. A frequent problem is users get an error such as:

ClassNotFoundException : Cannot load SchemaTypeSystem. Unable to load
class with name
schemaorg_apache_xmlbeans.system.s68C41DB812F52C975439BA10FE4FEE54.TypeSystemHolder.
Make sure the generated binary files are on the classpath.

The TypeSystemHolder.class generated by WSDL2Java must be placed in
your classpath in order to avoid this error."

For example, when I run WSDL2Java, I do it thru an ant task:

<target name="wsdl2java" depends="clean,prepare">
<delete dir="output" />
<java classname="org.apache.axis2.wsdl.WSDL2Java" fork="true">
<classpath refid="axis.classpath"/>
<arg value="-d"/>
<!-- none ??? -->
<arg value="xmlbeans"/>
<arg value="-uri"/>
<arg file="wsdl/Maragato.wsdl"/>
<arg value="-ss"/>
<arg value="-ssi"/>
<arg value="-g"/>
<arg value="-sd"/>
<arg value="-o"/>
<arg file="output"/>
<arg value="-p"/>
<arg value="br.com.atlantico.maragato.webservices.endpoint"/>
</java>

<!-- Move the schema folder to classpath-->
<move todir="${build.classes}">
<fileset dir="output/resources">
<include name="*schema*/**/*.class"/>
<include name="*schema*/**/*.xsb"/>
</fileset>
</move>

</target>

In this case, I get:

build/classes/schemaorg_apache_xmlbeans/system/sC4DADC577FF83F46C2C248EE4254F70D/TypeSystemHolder.class

I just confirmed that still works with todays svn.

Thanks for your response, Robert.

I did some more looking, and found that my IDE (IntelliJ Idea) was hiding
the class file that was generated from me, so I didn't know it existed. I
also found that the specific run target that I was using wasn't including
the resources directory in the class path like I thought it was. I had set
up Idea to include the directory in the source path for compilation, not the
class path, assuming that what was going to be generated was Java source
code rather than a class file. I am still a bit surprised that an actual
class file is being generated here, particularly after looking at the code
in WSDL2Java which does it by copying and modifying an existing class file
(!). With the directory now properly included in my runtime class path, the
code now seems to run correctly.

Hi, folks.
I just ran WSDL2Java (from yesterday's nightly build), and

generated a

written with those output files. Whenever I try, however, I get the

I have verified that the generated 'resources' directory is in my
classpath. I have also verified that there exists a

subdirectory of it

Post by Derek
named
schemaorg_apache_xmlbeans/system/s3F178E0A50CC587BC745803A994CE78D.
However, there is no TypeSystemHolder class in that directory
(although there are a bunch of .xsb files in it).
I am rather flummoxed as to what to do. Has anybody seen

this before?

This means that the next
person who does <blah> hits the same problem, and MAYBE eventually resolves
it by searching the mailing list archive, or maybe just wanders off and
finds another SOAP server with a less user-hostile interface.

Actually, I did. I wandered off to Axis 1 and found the error output of
the old WSDL2Java more helpful, which eventually led me to those online
validators.
