hello.
I need to develop an eclipse plug-in which access an AS400 DB. Therefore I
want to include a jar file ("ibm toolbox for java") into my plug-in
project and use a certain class ("AS400JDBCDriver") to connect to the DB.
But I can't figure out how to do this. I added the jar in the java build
path and when I try to connect to the DB, like this:
- Connection con = DriverManager.getConnection("jdbc:as400://" + host,
username, password);
...I get this exception:
java.sql.SQLException: No suitable driver
I tried to implicitly associate the JDBCDriver with my class using one of
these lines:
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
Class.forName("com.ibm.as400.access.AS400JDBCDriver",true,this.getClass().getClassLoader());
this.getClass().getClassLoader().loadClass("com.ibm.as400.access.AS400JDBCDriver ");
...but I always get the same "ClassNotFoundException" for the the class
AS400JCBCDriver.
Does it have something to do with not having an own main method? (the
plug-in is launched as a run-time workbench, of course)
When I try to access the AS400 DB from a java application it works.
Can anybody help me?
Thank you very much!
