Using a database in Sun's "Open Office"

Question

hi
I could think this tip is not suitable for this forum, but I didn't find another
so I try here to have an answer to a my question that, I think, can be interesting for other people too...
I would see in DataBase section of Sun's "Open Office" the data that my program register in a Derby database.
My first question is if this is possible..
If this is possible, my second question is: how to get the connection to the database?
*In the wizard , there are two components to put information in order to get the connection:
-(1) URL to the source data: jdbc: .....
-(2) Class of the driver:*
I made several tries to get the connection:
In the textBox (2) I put the path to the derby.jar that I use in the application
but when I push the button I got the message:
------"The driver JDBC wasn't load".------
Could I have same help about what information I have to put there ?
About the second input data, I think that in the box (1) I should put the (absolute) path to database that I would have the access..
but..., way it begin with jdbc: ?
Thank you for an explanation about what is the mean of the two components where put the input data....
regards

Answer 1

thank you jshell to spend time with your explanation..
I try to explain how I am seeing the problem:
In the Drby manual I read:
Derby consists of both the database engine and an embedded JDBC driver.
Applications use JDBC to interact with a database. Applications running on JDK 1.5 or earlier, must load the driver in order to work with the database.
In an embedded environment, loading the driver also starts Derby.
In a Java application, you typically load the driver with the static Class.forName method or with the jdbc.drivers system property.
For example: Class.forName("org.apache.derby.jdbc.EmbeddedDriver");In the java code I get a connection with this statements:
    private Connection getConnection(){ // 
            String driver = "org.apache.derby.jdbc.EmbeddedDriver";  // name of driver.
            try {
                Class.forName(driver);      // N.B. Derby.jar have to bein the classpath...
                System.out.println(driver + " loaded. ");
            } catch(java.lang.ClassNotFoundException e)     {
                System.err.print("ClassNotFoundException: ");
                System.err.println(e.getMessage());
                System.out.println("\n    >>> Please check your CLASSPATH variable   <<<\n");
            String  connectionURL = "jdbc:derby:" + path + dbName;
            Connection dbconn  = null;
            try {
                dbconn = DriverManager.getConnection(connectionURL);  // V.I. too
                System.out.println("Connected to database " + dbName);
            } catch (SQLException ex) {
                JOptionPane.showMessageDialog(null, ex.getMessage());
            } catch ( Exception excp ) {              // process remaining Exceptions here
                excp.printStackTrace();
        return dbconn;
    } // getConnection()At this point I think that I should give to Sun's Open Office the same intormation that I do in the java code ..
Of course I have to do it with a different syntax....
I think I have to put:
in the (1) the value of the String connectionURL
in the (2) the value of the String driver .
And to give the classpath to "Sun's Open Office" I should go in the menu option : [tools --> options --> OpenOffice.orgBase -- connection]
to activate the link with the driver derby.jar...
It was good for me talking with you was because now I think to see the problem in a more correct way..
What do you think about ?
