Subject [jira] Created: (GERONIMO-1532) NullPointerException when a badly named jar is put into repository directory

NullPointerException when a badly named jar is put into repository directory
----------------------------------------------------------------------------

         Key: GERONIMO-1532
         URL: http://issues.apache.org/jira/browse/GERONIMO-1532
     Project: Geronimo
        Type: Bug
    Versions: 1.0    
    Reporter: Heikki Linnakangas
    Priority: Minor
 Attachments: listURIs.diff

I copied a JDBC driver jar to geronimo/repository-directory, thinking that geronimo would
pick it up from there. What I didn't know, is that jars in the repository need to be named
in a particular way.

I then tried to add a Database pool using the wizard. I filled the name and type in step 1,
and clicked next. Instead of step 2, I got a blank screen, and this stack trace in the log:

14:30:33,322 ERROR [DatabasePoolPortlet] Unable to render portlet
java.lang.NullPointerException
	at org.apache.geronimo.console.databasemanager.wizard.DatabasePoolPortlet.loadDriverJARList(DatabasePoolPortlet.java:750)
	at org.apache.geronimo.console.databasemanager.wizard.DatabasePoolPortlet.renderBasicParams(DatabasePoolPortlet.java:721)
	at org.apache.geronimo.console.databasemanager.wizard.DatabasePoolPortlet.doView(DatabasePoolPortlet.java:625)
	at javax.portlet.GenericPortlet.doDispatch(GenericPortlet.java:250)
	at javax.portlet.GenericPortlet.render(GenericPortlet.java:178)
...

The culprit seems to be the FileSystemRepository.listURIs-method, that doesn't handle invalid
filenames properly, but returns nulls in the array it returns instead.
