We are currently using axis to implement mathematical web services.
In our last example, I have installed a service for Symbolic Integration at:
http://perseus.risc.uni-linz.ac.at:8080/axis/services/SymbolicIntegration?wsdl
We can use the service by a hand-written client however trying to
generate the java classes automatically using wsdl2java yields the
following error.
java.io.IOException: Type http://www.openmath.org/OpenMath:OMOBJ is
referenced but not defined.

org.apache.axis.wsdl.toJava.SymbolTable.checkForUndefined(SymbolTable.jav
a:405)

org.apache.axis.wsdl.toJava.SymbolTable.add(SymbolTable.java:331)

at
org.apache.axis.wsdl.WSDL2Java$WSDLRunnable.run(WSDL2Java.java:725)
at java.lang.Thread.run(Thread.java:484)
I have also tried to manually rewrite the wsdl description by importing
the OpenMath schema (see attachment) and I get again:
java.io.IOException: Type http://www.openmath.org/OpenMath:OMSTR is
referenced but not defined.

Any hint?
Thank you
