Bundles in usr and pickup behave differently [message #559602]

I use Virgo Web Server 2.1 M4. In my following test, I always use "startup -clean" for each case.

I downloaded com.springsource.org.apache.commons.pool-1.5.3.jar and com.springsource.org.apache.commons.dbcp-1.2.2.osgi.jar.

(1) if I placed the above two jars in pickup, I got:
Resolver report:
An Import-Package could not be resolved. Caused by missing constraint in bundle <com.springsource.org.apache.commons.dbcp_1.2.2.osgi>
constraint: <Import-Package: org.apache.commons.pool.impl; version="[1.3.0,2.0.0)">

(2) if I placed the two jars in usr. Only "org.apache.commons.pool" is deployed. "org.apache.commons.dbcp" is not deployed, It is not listed in the Bundles page of Admin Console. No any error in the log.

(3)If I placed "org.apache.commons.dbcp" in pickup, and "org.apache.commons.pool" in usr seperately. The two bundles deployed successfully. Then I tried to deploy my datasource bundle. It has to be placed in pickup. If it is placed in usr, it won't be deployed.

Is this the expected behavior or a bug in Virgo?

If it is the expected behavior, could you explain the difference between usr and pickup directory. From the user guide, it seems that pickup directory is only for hot deploy.

Thanks!

Hi Guofeng,

This is expected behaviour, the pickup directory is a watched directory for you to deploy your application bundles and artifacts to. The repository/usr directory is also a watched directory but bundles and other artifacts in it will not be hot-deployed, it is for your applications dpendancies.

From your description below, you should place both the commons bundles in the usr directory and, if needed, they will be started when you deploy an application bundle.

More information can be found in the User guide http://www.eclipse.org/virgo/documentation/virgo-documentati on-2.1.0.M04-incubation/docs/virgo-user-guide/html/ch08.html and http://www.eclipse.org/virgo/documentation/virgo-documentati on-2.1.0.M04-incubation/docs/virgo-user-guide/html/ch06.html

Hope this helps,
Chris.

That's pretty crucial information Chris, and the User Guide doesn't even hint at that difference.
It states "Virgo regularly scans watched repositories so it automatically picks up any changes to the artifacts in the directory at runtime", where 'picks up' and 'artifacts' are really way too vague to explain this difference.
