Custom client-side deserialization...

[Brian Abbott <br...@awarepoint.com>]

Hi,

 

            I'm writing an AXIS client deserializer. However, I had problems
with it regarding type identification and handling so, I went back to using
the BeanSerialization facilities provided by AXIS. However, that has the
same issues. The problem is that when I send out a SessionResponse object
which has one element "SessionID", the engine throws a "Bad Types" exception
which is thrown on line 258 of RPCHandler in the org.apache.axis.message
package. The exception I receive is as follows:

 

Jan 26, 2004 11:43:13 AM org.apache.axis.client.Call invoke

SEVERE: Exception:

org.xml.sax.SAXException: Bad types (class java.lang.String -> class
package.SessionResponse)

org.apache.axis.message.RPCHandler.onStartChild(RPCHandler.java:258)

        at org.apache.axis.client.Call.invoke(Call.java:2171)

        at org.apache.axis.client.Call.invoke(Call.java:1691)

 

And, the XML being sent out and received by the code above is as follows:

 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

 <soapenv:Body>

  <ns1:SessionResponse
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:ns1="myNS">

   <ns1:SessionID
xsi:type="xsd:string">E643B038C5A6EE93ED7B6827B0368338</ns1:SessionID>

  </ns1:SessionResponse>

 </soapenv:Body>

</soapenv:Envelope>

 

However, If I send the XML below, no exception is thrown but the value of
SessionID is null.

 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

 <soapenv:Body>

  <SessionResponse>

   <ns1:SessionID
xmlns:ns1="myNS">F002D0BEBAA95491ECD2C15B0EBE1A5E</ns1:SessionID>

  </SessionResponse>

 </soapenv:Body>

</soapenv:Envelope>

 

Any help or ideas would be greatly appreciated.

 

Thank you,
