I recently got this error: java.lang.NoClassDefFoundError:
org/apache/commons/logging/LogFactory
and I have this strange feeling that I was told here not to use commons
logging together with Spring DM.

I am as always having great problems with logging.... :(

Anyway iBatis seems to need that... Anyone know what logging it was I wasn't
supposed to use? (and if this what is what I can do?)

btw: I am still on v.[1.0.0.rc1] how difficult / worth it is an upgrade?

commons-logging is indeed the problem.

I am use PaxLogging and it seems to work fine.

http://wiki.ops4j.org/dokuwiki/doku.php?id=pax:logging

You can also use the Simple Logging Facade for Java

http://www.slf4j.org/

but i found that had circular dependency issues that pax did not.

I am pretty sure that we are using this one. (It wasn't me setting up the
logging and now the guy seems a bit hard to reach (the problem of open
source I guess)) But I still have a bundle needing
org/apache/commons/logging/LogFactory. Am I in trouble? I mean I probably
have to give it access to that class somehow right?

The bundle

jcl104-over-slf4

has this class, and assuming that your version of this bundle is new enough to have org/apache/commons/logging included it's Export-Package line in the manifest, than your bundles can use it.

try slf4j-api, slf4j-log4j (or other wired implementations) and
jcl104-over-slf4j.
The last jar is the one that provides the commons logging APIs - w/o,
the commons logging classes will not be available.

rc1 is sort of old but I don't think you'll have many problems. If you
encounter any check out the changelog and as always, use the forum or
this mailing list.

Cheers,
