oracle exception in my own soap service

[Jerzy Kut <je...@rzeszow.tiger.com.pl>]

Hi!
I have got:
- tomcat4.0.2
- soap2.2
- linux2.4.3 redhat6.2

I wrote simple application that uses oracle database.
SOAP and ORACLE are on same machine.
My service is declared as:


public class DBService {

  public DBService() {}

  public String doQuery(String input) {

    String result = "GRUPA\t" + "OPIS\n";

    // some code works with oracle and fill in result

    return (result);
  }

  public static void main(String[] args) {
    DBService service = new DBService();
    String result = service.doQuery("jerzyk");
    System.out.println(result);
  }
}

Service is deployed as:
'DBService' Service Deployment Descriptor
ID: DBService
Scope: Application
Provider Type: java
Provider Class: DBService
Use Static Class: false
Methods: doQuery

and Client is defined as:

public class DBClient
{
   public static void main(String[] args) throws Exception
   {
      try
      {
         URL url = new URL("http://localhost:8080/soap/servlet/rpcrouter");
         String name = "jerzyk";

         // Build the call.
         Call call = new Call();
         call.setTargetObjectURI("DBService");
         call.setMethodName("doQuery");
         call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
         Vector params = new Vector();
         params.addElement(new Parameter("input", String.class, name,
null));
         call.setParams(params);

         // Invoke the call.
         Response resp = null;
         try
         {
            resp = call.invoke(url, null);
         }
         catch( SOAPException e )
         {
            System.err.println("Caught SOAPException (" + e.getFaultCode() +
"): " + e.getMessage());
            System.exit(-1);
         }

         // Check the response.
         if( !resp.generatedFault() )
         {
            Parameter ret = resp.getReturnValue();
            Object value = ret.getValue();
            System.out.println(value);
         }
         else
         {
            Fault fault = resp.getFault();
            System.err.println("Generated fault: ");
            System.out.println ("  Fault Code    = " +
fault.getFaultCode());
            System.out.println ("  Fault String  = " +
fault.getFaultString());
            System.out.println ("  Fault Entries = " +
fault.getFaultEntries());
            System.out.println ("  Fault URI     = " +
fault.getFaultActorURI());
         }
      }
      catch(Exception e)
      {
         e.printStackTrace();
      }
   }
}

My service works correctly when I try to run it from shell by:

$java DBService

but it didn't when I call it from shell by:

$java DBClient

It throws:

Generated fault:
  Fault Code    = SOAP-ENV:Server
  Fault String  = Exception from service object:
oracle/jdbc/driver/OracleDriver
  Fault Entries = null
  Fault URI     = /soap/servlet/rpcrouter

I have got oracle driver classes12.zip and I have got set
CLASSPATH=path/to/oracle/driver/classes12.zip

Where is reason?

Best regards
