Connection to PervasiveSQL fails

Hello!
I'm trying to connect to a PervasiveSQL Server but I fail.
The driver that I use is pvjdbc2.jar (pvjdbc2x.jar might be needed).

Here is my code
Class.forName("com.pervasive.jdbc.v2.Driver");
String url = "jdbc ervasive://database_host_name:1583/source_name";
DriverManager.getConnection(url, username, password);

But here is the stacktrace of the exception that it throws

I guess it requires additional jar file (since it cannt find an inner class).
But I walked through forums and saw that everybody connects just using only that jar file.
Maybe you can forward onto a page where I can get another driver for PervasiveSQL?
PLEASE HELP!
Thank you!

It looks like your jar file is missing from the classpath.
Make sure to add pvjdbc2.jar to your classpath (WEB-INF/lib if using web container)
Good luck

I'm using IntelliJ IDEA4.5.
I add pvjdbs2.jar to my libraries where rt.jar, etc. resides.
The strange thing is that the Pervasive-JDBC guide says that
I need only to download the pvjdbc2.jar, add it to my classpath
and write this
DriverManager.registerDriver("com.pervasive.jdbc.v2.Driver");
or
Class.forName("com.pervasive.jdbc.v2.Driver").newInstance();
DriverManager.getConnection(url, username, password);
But doesnt work!
Please help!
Thank you!

This effectively modifies our Java installation, which is generally considered to be a bad idea. For example, it makes it very difficult to have projects that use different versions of the driver.

Instead, jars should be placed in a directory associated with the directory where your compiled classes will reside. For example, in a J2EE web application, there is a "WEB-INF" directory, which contains a "classes" directory and a "lib" directory; "lib" is where application jars go. For a non-J2EE project, you have more flexability in where things are stored, but it's not a bad model to emulate.

Also, most IDEs don't use any externally set CLASSPATH; instead, each project has it's own CLASSPATH. So you need to pick a good location for the driver jar, and then make sure that location is part of your project's classpath.

If I had to pick a good location for my jar file then I guess I had to
do it with any other jar that I ever used.
But when connecting to a mySQL database with the aid of the jtds1-1.jar
driver I just need to add it to my libraries
In IntelliJ IDEA you do it by File->Settings->Libraries(Classpath) tab
then Add jar/directory.
And everything works fine.
If you have any difficulties helping me out could you please forward
me onto a page where I get another driver for Pervasive.SQL.
I know that there is another driver PervasiveSQL.jar.
But I searched all the net for it but couldnt find it.
Maybe you can help me?
Waiting for reply.........
Thank you!

The connection works if you add the two other jar files from the Pervasive driver bin folder, the jpscs.jar and the pvjdbc2x.jar.

The last post did the trick - the library jpscs.jar - that was the kicker.
Thank you sooo much!
