I have an Apache SOAP server set up in tomcat, the server side works
fine, and I can see through the Eclipse TCP/IP monitor that it is
returning the correct data. What I can't figure out is how to parse out
the simple Integer[] array when it gets back to the client. I've been
googling and reading documentation for two days, and am still drawing a
blank, so I'm asking for help here.
Below are listed some code excerpts, the Descriptor and SOAP request and
response packets. You can see that the response is a simple array of
integers, but I continually get ClassCastExceptions when I try to read
out the data at the end. I'm guessing it's just some stupid little
thing I'm missing, but I sure can't see it, and any suggestions will be
greatly appreciated!!
This is the applicable piece of the client code. The stuff that is
commented out is stuff I've tried and which failed to work:
Response resp = call.invoke(url, "" );
if ( resp.generatedFault() ) {
System.out.println( "The call failed: " );
} else {
Parameter result = resp.getReturnValue();
// Integer[] result = resp.getReturnValue();
System.out.println( "Rtn val = " + result.getValue());
System.out.println( "resp Object type: " + result.getClass());
System.out.println( "resp Object toString: " +
result.toString());
// Integer[] rtnValues = ( Integer[] ) result.getValue( );
EddSrvResponse rtnValues = ( EddSrvResponse ) result.getValue();
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is where I get the ClassCastExecption.
/* for ( ii = 0; ii < rtnValues.length; ii++ )
System.out.println( rtnValues[ ii ]);
}
*/
System.out.println( "XID : " + rtnValues.getXID() );
System.out.println( "Status: " + rtnValues.getStatus() );
// Integer r = (Integer) result.getValue();
// System.out.println( "Xid:" + r);
// System.out.println( result[0] );
EddSrvResponse is defined as:
public class EddSrvResponse {
private Integer xID;
private Integer status;
and has appropriate setters and getters which I won't bother to list here.
The Descriptor:
<?xml version="1.0" encoding="UTF-8"?>
<isd:service xmlns:isd="http://xml.apache.org/xml-soap/deployment";
id="urn:wraEddServer">
<isd:provider type="java"

methods="getDataLine">
<isd:java class="eddSrv.getDataLine"/>
</isd:provider>
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>
</isd:service>
The SOAP request:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
