Creating a new connection when creating a report from scratch

Question

I've searched all around but I haven't managed to find any samples or forum posts that show how to create a connection when creating a report from scratch via RCAPI.  All of the code that I've found has been aimed at replacing the ConnectionInfo for an existing connection.  I figured that it would work something like this:
m_crystalReport.setReportAppServer(ReportClientDocument.inprocConnectionString);
m_crystalReport.newDocument();
IConnectionInfo ci = new ConnectionInfo();
PropertyBag propertyBag = new PropertyBag();
propertyBag.put("Use JDBC", true);
propertyBag.put("Connection URL", "jdbc:jtds:sqlserver://localhost:1433;databaseName=" + DB_NAME);
propertyBag.put("Database Class Name", "net.sourceforge.jtds.jdbc.Driver");
propertyBag.put("Database DLL", "crdb_jdbc.dll");
ci.setAttributes(propertyBag);
m_connection = new Connection();
m_connection.setConnectionInfo(ci);
m_connection.open();
but this produces a NullPointerException within Connection.open().  If I leave the connection closed but add it to the report via DatabaseController.addConnection() then I just get the exception later on when I try to add tables using the connection.
Can anyone give me any pointers please?
Thanks,
Rich.

Answer 1

Just in case anyone else runs into this, I managed to fix it by leaving the connection closed and then using the connection info instead of the connection when creating tables, eg:
     ITable t = new Table();
     t.setAlias(v.getAlias());
     t.setName(v.getView().getName());
     t.setConnectionInfo(m_connectionInfo);
     getDatabaseController().addTable(t, null);
