Hello, I have a question that I hope someone can help me with..
I am deploying a class that contains methods that can throw exceptions.
Whenever an exception is thrown, my client receives a '(500)Internal
Server Error'. The following appears in the tomcat log file:
2004-01-13 17:31:23 StandardWrapperValve[rpcrouter]: Servlet.service() for
servlet rpcrouter threw exception
javax.servlet.ServletException: Error building response envelope:
java.lang.NullPointerException
at
org.apache.soap.server.http.RPCRouterServlet.doPost(RPCRouterServlet.java:418)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:763)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
(etc)
I have deployed using the following descriptor:
<!-- generated by vu.globe.svcs.gloap.apache.GenGloapDeployDescriptor -->
<isd:service xmlns:isd='http://xml.apache.org/xml-soap/deployment'
id='http://gloap.gdn.apps.gaia.vu'>
<isd:provider type='java'
scope='Session'
methods='bind getFileTraceInfo'>
<isd:java class='vu.gaia.apps.gdn.gloap.PackageGloapSession' static='false'/>
</isd:provider>
<isd:faultListener>org.apache.soap.server.DOMFaultListener
</isd:faultListener>
<isd:mappings>
<isd:map
encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'
xmlns:x='http://gdn.apps.gaia.vu' qname='x:getFileTraceInfoResults'
javaType='vu.gaia.apps.gdn.getFileTraceInfoResults'
java2XMLClassName='org.apache.soap.encoding.soapenc.BeanSerializer'
xml2JavaClassName='org.apache.soap.encoding.soapenc.BeanSerializer'
/>
</isd:mappings>
</isd:service>
On the server side I am using Apache Soap 2.3.1, Tomcat 5.0.16, Xerces
1.4.4. My client is using Axis 1.1.
I have tried throwing RemoteException, a subclass of RemoteException, and
'Exception'. The same happens in each case. The deployed class works fine
as long as no exceptions are thrown.
Help would be much appreciated..
Patrick
