Access DB Connect Issues

[Bill Warner]

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

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

String database = "jdbcdbcriver={Microsoft Access Driver (*.mdb)};DBQ=";database+= filename.trim();

try this

String url ="jdbcdbcRIVER={Microsoft Access Driver
(*.mdb)};DBQ= c:\\IssuanceTracker\\IssuanceTracker.mdb";

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.
