[jboss-user] [JBossWS] - Bug? operations from doc-literal BARE to WRAPPED

Wed Feb 14 14:21:29 EST 2007

Hi all,
I'm completely stuck on this, please could you confirm thsi is a bug or where I'm wrong?
I'm using JBossWS1.0.4 as client of an Axis2 service. Until now everything was ok, then...
I removed two methods from a working POJO class exposed as WS and I started getting a ClassCastException at runtime on my JBoss JSR109 client side calling the remaining methods. Suddendly all my operations are seen as "doc-literal wrapped"

For example:

  |   public String getConfigurationFile ()
  |   {
  |     return "abracadabra";
  |   }
  | 

This is the Exception trace:

I enabled JBossWS logs and I started digging...

If I insert again the two methods in my POJO WS and I generate again WSDL and client artifacts, this is the happy day scenario:

  | 2007-02-14 15:56:45,897 TRACE [jbossws.SOAPMessage] Incoming Response SOAPMessage

  | </soapenv:Envelope>

I compared the two WSDL before and after the two method inserted and nothing is changed for the getConfigurationFile() method. (I can post them, if needed).
Looking into the JBoss logs I discovered that on the correct scenario all operations are seen as doc-literal BARE

  | OperationMetaData:
  |  qname={http://neo.spectre.com}getConfigurationFile
  |  javaName=getConfigurationFile
  |  style=document/literal/BARE
  |  oneWay=false
  |  soapAction=urn:getConfigurationFile
  | ReturnMetaData:
  |  xmlName={http://neo.spectre.com/xsd}getConfigurationFileResponse
  |  xmlType={http://neo.spectre.com/xsd}>getConfigurationFileResponse
  |  javaType=com.spectre.neo.GetConfigurationFileResponse
  |  mode=OUT
  |  inHeader=false
  |  wrappedVariables=[]
  |  wrappedTypes=[]
  |  wrappedElementNames=[]

When I'm getting thw ClassCastException the same operation is seen as doc-literal WRAPPED:

  | OperationMetaData:
  |  qname={http://neo.spectre.com}getConfigurationFile
  |  javaName=getConfigurationFile
  |  style=document/literal/WRAPPED
  |  oneWay=false
  |  soapAction=urn:getConfigurationFile
  | ReturnMetaData:
  |  xmlName={http://neo.spectre.com/xsd}getConfigurationFileResponse
  |  xmlType={http://neo.spectre.com/xsd}>getConfigurationFileResponse
  |  javaType=com.spectre.neo.GetConfigurationFileResponse
  |  mode=OUT
  |  inHeader=false
  |  wrappedVariables=[_return]
  |  wrappedTypes=[]
  |  wrappedElementNames=[]
  | 

thank you in advance
