如何使用Jboss 5.0.0 GA与Java中的MSAccess数据库连接

Question

I have problem with connecting Dynamic Web Project and database MS Access. I'm using Eclipse Juno, and Jboss 5.0.0 GA. I know that i have to define datasource xml. But I don't know what I'm doing wrong.I stored msaccess-ds.xml in jboss-5.0.0.GA\\server\\default\\deploy folder.

<?xml version="1.0" encoding="UTF-8"?>

<datasources>
  <local-tx-datasource>
    <jndi-name>MSAccessDS</jndi-name>
    <!-- format of URL is "jdbc:odbc:DSNNAME" -->
    <connection-url>jdbc:odbc:C:\Users\Tazz\Desktop\bazaAccess\baza niekod\tabele Faelbud całość_wb.mdb</connection-url>
    <driver-class>sun.jdbc.odbc.JdbcOdbcDriver</driver-class>
    <user-name></user-name>
    <password></password>
  </local-tx-datasource>

</datasources>

And here is my Java Code:

public static void connectMSAccess(){

        try {
            InitialContext cxt = new InitialContext();
            DataSource ds = (DataSource) cxt.lookup( "java:comp/env/MSAccessDS" );
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

}

And this is my problem:

I created simply console application to connecting with this database and everything was ok, but there i didn't have to use datasource and jboss. Please help me!
