Question

I’ve got an application, where I use a JDBC connection. When I run it from the Eclipse environment, there’s no problem.
But, when I pack it into jar, the line

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

causes an exception:

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Unknown Source)

I put a line into manifest file, but it didn’t help:

Class-Path: sqljdbc4.jar

Can anyone help?

Answer 1

I finally solved the problem.
I installed the jdbc driver also on the remote server, and I packed the files to an executable jar (not only jar as before).
