java.lang.ClassCastException: com.ibm.wsdl.extensions.schema.SchemaImpl

Hi,

I'm trying to parse wsdl files - with complex types.  I'm using wsif 2.0 to
do this.

my code stalls at this line

line30 -  Parser.getTypeMappings(def, table);

and I get this exception

java.lang.ClassCastException: com.ibm.wsdl.extensions.schema.SchemaImpl
     at org.apache.wsif.schema.Parser.getTypesSchemas(Unknown Source)
    at org.apache.wsif.schema.Parser.getTypeMappings(Unknown Source)
    at org.apache.wsif.schema.Parser.getTypeMappings(Unknown Source)
    at Dependency.main(Dependency.java:30)

Any ideas on how to solve this?
Any help would be really appreciated.  I dont know what the problem is.
