Java stored procedure not working

Question

I have done the following:
loadjava -user lodonnel/lodonnel@albacore:1521:DEVAN -thin -force -resolver "((* lodonnell) (* public) (* -))" -v c:/usr/lod/java/dev/dbDir/displayStringsDB.jar
Then:
CREATE OR REPLACE FUNCTION LODONNEL.getSellingTitleDefinition( sellingID
NUMBER, week VARCHAR2, netID NUMBER, moduleID NUMBER)
RETURN VARCHAR2 AS LANGUAGE JAVA NAME
'com.msa.gabriel.share.displaystrings.util.DatabaseAccess.getSellingTitleDefinition( int, java.lang.String, int, int ) return java.lang.String';
Variable myString VARCHAR2;
Call getSellingTitleDefinition( 3247, '02-11-2002', 2, 2) INTO :myString;
I receive the following error:
Message 1: ORA-29532: Java call terminated by uncaught Java exception: java.lang.VerifyError: Error detected by bytecode verifier when class was created
Executing Command:
Call getSellingTitleDefinition( 3247, '02-11-2002', 2, 2) INTO :myString
Can someone help me determine where to look for this problem?
The java classes being loaded do contain references to classes that I have not included in the jar, but from what I read the loadjava command I made should allow this. The code that would run in the procedure will not call any of the referenced classes that are not loaded here.

Answer 1

I cut out all the functionality, and these are the two classes I am trying to load and run:
package com.bob.gabriel.share.displaystrings.util;
import java.sql.SQLException;
import java.util.HashMap;
import com.bob.media.displaystrings.util.DisplayStrings;
public class DatabaseAccess {
public static String getSellingTitleDefinition( int sellingID,
                              String week, int
                              netID, int
                              moduleID ) throws
     SQLException {
     HashMap databaseArgs = new HashMap();
     databaseArgs.put( "ID", new Integer( sellingID) );
     databaseArgs.put( "WEEK", week );
     HashMap formatterArgs = new HashMap();
     formatterArgs.put( "NETWORKID", new Integer( netID ));
     formatterArgs.put( "MODULEID", new Integer( moduleID ));
     return DisplayStrings.getDisplayString();
package com.bob.media.displaystrings.util;
import java.util.Collection;
import java.util.HashMap;
import java.sql.SQLException;
public class DisplayStrings {
public static String getDisplayString() throws SQLException {
     return "woohoo!";
* This static method is used as the common interface to return the specified formatted string.
* @return formatted String to display on a UI
* @param String - some kind of indicator of class that knows how to retrieve data?
* @param HashMap - map of args needed to get the requested data.
* @return formatted String to display on a UI
* @param HashMap - map of args needed to get the format
* information of the requested data.
public static String getDisplayString( String type, HashMap databaseArgs, HashMap formatterArgs ) throws SQLException {
     try
//      System.out.println( "in getDisplayString" );
//      DisplayStringsDAO dao = getDAO( type );
//      System.out.println( "got dao: " + dao );
//      List data = dao.getUnparsedData( databaseArgs );
//      System.out.println( "got List of data:" + data );
//      Formatter formatter = getFormatter( type );
//      System.out.println( "got formatter" );
//      formatter.initialize( formatterArgs );
//      System.out.println( "initialized formatter" );
//      return formatter.format( data );
     return "got here am ok";
     catch ( Exception e )
     throw new SQLException ( "could not format requested string. " +
               e.getMessage() );
I build a jar file for them called displayStrings.jar
I use the following load command:
loadjava -user lodonnel/lodonnel@albacore:1521:DEVAN -thin -force -resolver "((* lodonnell) (* public) (* -))" -grant public -v c:/usr/lod/java/dev/dbDir/displayStringsDB.jar
and the following create function command:
CREATE OR REPLACE FUNCTION LODONNEL.getSellingTitleDefinition( sellingID
NUMBER, week VARCHAR2, netID NUMBER, moduleID NUMBER) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'com.bob.gabriel.share.displaystrings.util.DatabaseAccess.getSellingTitleDefinition( int, java.lang.String, int, int ) return java.lang.String';
When I try this in SQLPlus:
call getSellingTitleDefinition( 3247, '02-11-2002', 2, 2) into :theString;
I get this:
call getSellingTitleDefinition( 3247, '02-11-2002', 2, 2) into :theString
