The following code:

public Connection getConnection(){
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String filename = "c:/IssuanceTracker/IssuanceTracker.mdb";
String database = "jdbcdbcriver={Microsoft Access Driver (*.mdb)};DBQ=";database+= filename.trim();
System.out.println(database);
Connection con = DriverManager.getConnection( database ,"","");
return con;
}
catch (Exception e) {
System.out.println("Error: " + e);
e.printStackTrace();
return null;
}
}

Yields the following error:

java.lang.NullPointerException
at sun.jdbc.odbc.JdbcOdbcDriver.initialize(Unknown Source)
at sun.jdbc.odbc.JdbcOdbcDriver.connect(Unknown Source)
at java.sql.DriverManager.getConnection(DriverManager.java:538)
at java.sql.DriverManager.getConnection(DriverManager.java:188)
at issuancetracker.DataAccess.getConnection(DataAccess.java:27)
at issuancetracker.testmain.main(testmain.java:21)

I've included the rt.jar file in my project. I'm using WSAD 5.1.2. Can anyone please help. Thanks, Bill

Thanks for the replies! I get the same errors with the suggested changes.

I could really use some help. I'm new to Java and this problem doesn't seem to make sense. Co-workers can execute the same code successfully w/o error. Any help would be appreciated.

Instead of accessing the MDB file directly, have you tried setting up an ODBC data source? Some info about that can be found here.
 
Don't get me started about those stupid light bulbs.
