4. Re: classpath to external jar files
adrian.brock Mar 4, 2002 9:40 AM (in response to oli306)The archive and codebase attributes are for the jar
containing the ClassPathExtension MBean.
ARCHIVE="jboss.jar"
CODEBASE="../../lib/ext"
Also, you can only do one URL in each extension.
You will need two MLETs for two directories.

5. Re: classpath to external jar files
oli306 Mar 4, 2002 10:45 AM (in response to oli306)ok,
that's my line :
and my beans still not find the path to external libraries.
I must do something more ? -
6. Re: classpath to external jar files
adrian.brock Mar 4, 2002 11:05 AM (in response to oli306)Try
Translateed, this says run org.jboss.util.ClassPathExtension from
../../lib/jboss.jar passing the single String parameter
{your directory}
I'm not sure, you have to add the prefix file:/ for
fully qualified directories?
If you specify a directory that contains jars, the
MBean loads all jars in the directory.
It will however ignore everything else, e.g. classes
and property files.

7. Re: classpath to external jar files
oli306 Mar 4, 2002 12:12 PM (in response to oli306)oh yeah, that's fine now, thank you.
And to include directories for property files or conf files, I should add one mor ARG tag with the directory name or these lines only deal with jar files ? -
8. Re: classpath to external jar files
adrian.brock Mar 4, 2002 12:43 PM (in response to oli306)The classpath extension works in three modes.
1) You specify a url to a jar
it adds that jar
2) You specify a url to a directory containing jars
it adds those jars
3) You specify a url to a directory not containing jars
it adds the directory to the classpath
Option 3 will add classes/property files providing
the directory does contain jars.

9. Re: classpath to external jar files
adrian.brock Mar 4, 2002 12:45 PM (in response to oli306)Sorry,
The last line should read
Option 3 will add classes/property files providing
the directory does NOT contain jars.

10. Re: classpath to external jar files
adrian.brock Mar 4, 2002 12:47 PM (in response to oli306)And also for more entries, you need a whole new
MLET.

11. Re: classpath to external jar files
fstarsinic Mar 5, 2002 3:16 PM (in response to oli306)with JBoss 3...
My application is jar'd up and put in lib/ext directory (afsp.jar). the ejb part of the application is jar'd up separately and deployed into the deploy directory (BaseMDBConsumer.jar), but I end up getting a NoClassDefFound Error when the ejb makes a call to a class in afsp.jar, even though my jar file (afsp.jar) has been put into lib/ext.
[11:25:21,990,AutoDeployer] Deployment failed:file:/C:/packages/jb3/deploy/BaseMDBConsumer.jar
org.jboss.deployment.J2eeDeploymentException: Error while starting BaseMDBConsumer.jar: gov/ca/boe/util/BOEException, Cause:
java.lang.NoClassDefFoundError: gov/ca/boe/util/BOEException
why is that? am i doing something wrong?
thanks,

12. Re: classpath to external jar files
davidjencks Mar 5, 2002 8:52 PM (in response to oli306)I'd expect this problem with jboss 3 alpha, be only mildly surprised with jboss 3 beta, and be very surprised with the cvs version. For alpha, you'd have to put your jar in the list of jars to load from lib/ext in conf/default/jboss-service.xml. Other versions, this is taken care of automatically.

13. Re: classpath to external jar files
fstarsinic Mar 6, 2002 1:19 AM (in response to oli306)thanks dave.
i've been using jboss for several months now and have it running version 2.4.1a in production. i've never understood (or got working) any application deployed in what i would call the excepted way. i have decided to create my CLASSPATH and start JBoss by modifying run.bat so it uses the CLASSPATH that i configure. So, i do not put any jar files in lib/ext at all.
I'd like to do it the "REAL" way by using lib/ext and starting JBoss properly.
I have a small EJB (Message Driven Bean). It really does nothing at all except makes a call to a Workflow Engine that I wrote with the contents
of the JMS message (an object message) The workflow engine tears apart the object message and "does stuff".
So most of my code is in a jar file called "afsp.jar" that the EJB calls.
i thought that i could drop my ejb jar file in the deploy directory, drop my war file in the tomcat webapps directory, drop my jar file and all the other jar files in the lib/ext directory and the ejb would find everything and all would work. is this how you would expect it to work?
aparently you're saying with verison 3 dropping files in lib/ext doesn't do it without extra work. i can accept that.
in production, we're using 2.4.1a and i thought i had the same problem.
i'll revisit this approach with JBoss 2.4.1a. I just want to make sure i'm not off base with my approach for how to make the EJB see my afsp.jar file.
i was also trying to create an MBean and have had no luck getting it to start. i'm assumming it's for the same reason. it cannot see afsp.jar
any feedback you could provide would be greatly appreciated.
thanks,
frank
