Hi,
I have created a connection pool in Weblogic.I want to access the pool from my client.
There is one remote interface which is defined as follows
ResultSet executeDataBaseQuery(Connection conn,
String queryString) throws RemoteException;
My bean implements this interface and sends back the resultset
as follows
public ResultSet executeDataBaseQuery(Connection conn,String queryString)
{
Statement stmt=null;
ResultSet result=null;
try
{
if (conn==null)
{
System.out.println("Connection is null");
}
System.out.println("Inside bean first stmt");
stmt = conn.createStatement();
result=stmt.executeQuery(queryString);
stmt.close();
} catch(SQLException e)
{
System.out.println("Exception inside JDBCConnector.executeDataBaseQuery"+e.getErrorCode());
e.printStackTrace();
return null;
}
return result;
The client code is as follows
public Connection getConn() throws ClassNotFoundException, InstantiationException, IllegalAccessException
{
try
{
Connection conn = null;
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:weblogic
ool
raclePool");
System.out.println("Got a connection from
JDBC Pool");
if (conn == null)
{
System.out.println("Connection is null in the function getConn()");
}
return conn;
}
catch(Exception e)
{
System.out.println("Could not get free Connection from the pool "+e.getMessage());
e.printStackTrace();
return null;
}
}
When I call the above getconn() from the application it gives error message as
"Pool connect failed"
Could U please tell me where the problem is
Do reply
