How to fix: 'Driver class not found:
net.sourceforge.jtds.jdbc.Driver'
Hi all,
I am having problems with ManifoldCF and the MS SQL connector. No matter what I do I get a "Threw exception: 'Driver class not found: net.sourceforge.jtds.jdbc.Driver'" as connection status. I have tried building manifold locally and downloading the binary version but nothing seems to help. I have also tried to place the jtds.jar file in connector-lib , connector-lib-proprietary, example\lib , using jtds-1.3 , jtds-1.2 and the jtds.jar that ant make-deps gets for me. Both java 1.6.0_45 and 1.7.0_17 have been tried. All attempts have been made with the example application. The problem is on both Windows8 and Windows Server 2008 R2. Starting manifold and specifying jtds in the classpath directly doesn't help.
The only time ManifoldCF acknowledged the existence of the Driver-class at all was when I used jtds-1.3.jar with java 1.6. Since jtds 1.3 requires java 7 I got an exception in the command window complaining about an unsupported class version:
WARN org.eclipse.jetty.servlet.ServletHandler - /mcf-crawler-ui/viewconnection.jsp
javax.servlet.ServletException: java.lang.UnsupportedClassVersionError: net/sourceforge/jtds/jdbc/Driver : Unsupported major.minor version 51.0
[....]
at org.apache.manifoldcf.crawler.connectors.jdbc.JDBCConnection$TestConnectionThread.run(JDBCConnection.java:233)
The missing driver exception has not been seen in any logs so far.
While looking for the class I installed visualvm and tried to look around. After restarting manifoldcf a heapdump shows no signs of jtds.jdbc.Driver , after viewing the jdbc-connector and getting a "driver class not found" exception a new heapdump shows jtds.jdbc.Driver , 1 instance and size 16. That is the closest I got to the class.
I am now giving up and sorely need help.
Regards,
Christian.

Glad it worked out for you.
The reason we separate example and example-proprietary is that we cannot
include anything that is not licensed compatibly in the distributed build.
This is inconvenient for people but is unfortunately a legal necessity.
As for the alfresco download changes, I believe that's all been fixed up on
trunk. But if you check out trunk you should be able to verify that.
Thanks,
Karl

Hi Karl,
Using example-proprietary and not example did the trick. That was a bit embarrassing.
By the way (don't know if this belongs here or not) when compiling I had to point the alfredo-related things in build.xml from head to http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/COMMUNITYTAGS/V4.2c/root/projects/3rd-party/lib/ in order to find the jars to download.
Thanks!
Christian.

Hi Christian,
You definitely must build locally for this driver to be included in the war files etc. You must also build using ant, not maven. The procedure for building is:
(1) ant make-core-deps
(2) ant make-deps
(3) ant build
(4) cd dist/example-proprietary
(5) <java> -jar start.jar
Is this the process you are following? If not, can you try it this way?
If this doesn't work for you, I'll need to do further research, but I won't be able to do that until later this evening.

The jtds version this was last tested with was jtds 1.2.2.

Hi Christian,
You definitely must build locally for this driver to be included in the war
files etc. You must also build using ant, not maven. The procedure for
building is:

(3) ant build
(4) cd dist/example-proprietary
