How to use the Oracle's SET ROLE?

Question

Hi all,
does anyone know how I can call SET ROLE (for Oracle) from java before the report is produced with
Crystal Reports API?
I'm using Crystal Reports 2008 for the report design and new crystal report java sdk of JRC (v12.2 with SP1) which know as CRJ in my J2EE application.
I tried to insert a Command (SET ROLE role) into a working fine report.
The report runned into Crystal Reports 2008 works fine.
Since has been made a high number of reports without a SET ROLE, to avoid to modify all the reports already made, I tried to run the SET ROLE from JAVA adding a CommandTable to report.
Below the code inserted into java class:
          ConnectionInfos connInfos = new ConnectionInfos();
          IConnectionInfo iConnInfo = new ConnectionInfo();
          PropertyBag propertyBag = new PropertyBag();
          try {
          String usernameOracle = GestoreContesto.getAttributo("usernameOracleReport");
          String passwordOracle = GestoreContesto.getAttributo("passwordOracleReport");
          String connectString = GestoreContesto.getAttributo("dbUrl");
          String driverName = "oracle.jdbc.OracleDriver";
          //String driverName = "oracle.jdbc.OracleConnectionCacheImpl";
          //String JNDIName = "jdbc/nsisrdatasource";
          String userName = usernameOracle;               
          String password = passwordOracle;
          String TRUSTED_CONNECTION = "false";
          String SERVER_TYPE = "JDBC (JNDI)";
          String USE_JDBC = "true";
          String DATABASE_DLL = "crdb_jdbc.dll";
          //String JNDI_OPTIONAL_NAME = JNDIName;
          String CONNECTION_URL = connectString;
          String DATABASE_CLASS_NAME = driverName;
          propertyBag.put("Trusted_Connection", TRUSTED_CONNECTION);
          propertyBag.put("Server Type", SERVER_TYPE);
          propertyBag.put("Use JDBC", USE_JDBC);
          propertyBag.put("Database DLL",DATABASE_DLL );
          //propertyBag.put("JNDIOptionalName",JNDI_OPTIONAL_NAME );
          propertyBag.put("Connection URL", CONNECTION_URL);
          propertyBag.put("Database Class Name", DATABASE_CLASS_NAME);
          iConnInfo.setAttributes(propertyBag);
          iConnInfo.setUserName(userName);
          iConnInfo.setPassword(password);
          connInfos.add(iConnInfo);
          String TableName = "Custom_Query";
          String TableAlias= "Custom_Query";
          CommandTable table = new CommandTable ();
          table.setAlias (TableAlias);
          table.setName (TableName);
          table.setConnectionInfo(iConnInfo);
          table.setCommandText("SET ROLE role");
          databaseController.addTable(table, null);
          catch (ReportSDKException e) {
               System.out.println("......");
When I tries to render a report from Java I received this ERROR:
15:32:52,935 INFO  [STDOUT] 15:32:52,935 FATAL [JRCCommunicationAdapter] Request failed and JRC Command failed to be undone

It's a big problem. If anyone has any idea, I'd greatly appreciate it.
Thanks

Hi all,
running a report with two command from java (the first contains a simple "SEt ROLE role",
the second contains a simple select) is raised the error "No results returned by the query" while in
Crystal Reports 2008's preview the report works fine.
Therefore I ask: "Is it possible to run a report that contains a query without result from Java?
How can do with the SET ROLE command, which is essential for me?"
Thanks
