2.Once DataSource is created ,how to test wheater it is working fine or not?please help

Hello Prasad,
Don't create a new datasource, but create a datasource alias for the existing SAP<sid>DB datasource with your new name.
<u>(remember to restart the j2ee cluster)</u>
Then in your application instatiate the datasource and use your create/update/select statements.
<b><i>Once this is set up test from your java code as follows:</i></b>
InitialContext ic = new InitialContext(); 
DataSource mySource = (DataSource)ic.lookup("java:comp/env/jdbc/YourDataSource");
or.. DataSource mySource = (DataSource)ic.lookup("java:jdbc/YourDataSource"); <b>(can't remember which of the 2 worked)</b>
if this throws a NamingException, then your alias doesn't work, or perhaps you forgot to restart the cluster.
After this executes successfully, use the datasource freely.
Connection con = mySource.getConnection();
con.executeQuery
con.executeUpdate
con.executeStatement
ect...
And forget about oracle, sapdb, informix, db2, or whatever drivers. This makes your application portable and independent from the DB layer.
Please feel free to reward points if this solves your problem.
