How to fetch data from a Microsoft Access database through JDBC and insert the table as a test field in an Applet

Question

I have made a small letter game as a Java Applet. I have made a Microsoft Access Database through JBDC for the high scores.

I have managed to insert values (scores) into the database, but I am having trouble fetching them and displaying the table in the textArea of an ajFrame . I am not even sure if the connection is established. I have created the SQL statement for it.

Answer 1

If you've connected successfully then

   connection=DriverManager.getConnection("jdbc:odbc:databaseName");

should return you a connection object and not throw a SqlException.

So I would first check that the above is in fact the case.

Note that an applet can only talk back to its originating server (this is a security feature). So if your applet is served from server A, and your database is on server B, you should get security exceptions.

Answer 2

1. Check your query with sql prompt.

2. verify object name used (Drivermanager,Connection,TextField)

3. Include Exception handling code for sql statements (try and catch )
