Connecting to a remote MS SQL database using Java Connector


#1

Hello!

We would appreciate if any one could guide us in connecting to a remote MSSQL database using the Java Connector.

We are using the DHTMLx Grid component in a JSP Page . We already tried the following steps:

1> included the connector.jar file
2> implemented the following code:

GridConnector c = new GridConnector(conn);
c.render_table(“item_mast”, “id”, “code,name”);

We are able to connect to the database but the the above step(2) to populate the grid with the records in the “item_mast” table is not working.

If we can get an example, it would be great.

Thanks!

Try to enable server side logging and check the error details.

What do you mean by “implemented the following code:”
Are you creating new class on base of ConnectorServlet and override “configure” method, or just use the GridConnector class in wild ?
