1. why not use 

 url = "jdbc:derby://localhost:1527/posdb";
 but cocat literal substrings.

2. make sure the database posdb has been created and derby network server is started.

3. make sure you did not change the port number of derby.

Subject: establishment of the connection

Hi i want to establish a connection with an existing db posdb.

                url = "jdbc:derby://" + "localhost" + ":" + "1527" + "/" +
        new ClientDriver();
        Connection connection = null; 
        try {

            connection = DriverManager.getConnection(url, "sa", "123");
            return true;
        catch(Exception e)
            return false;
The application server rejected establishment of the connection.  An attempt
was made to access a database, posdb, which was not found.
