problem retrieving nodes from different workspaces
Hello I am having a problem retrieving nodes from different workspaces. I
have supplied a runnable example class.
In this class I am creating two workspaces and add some nodes to them. When
I retrieve the nodes without first shutting down the repository I am getting
a result as expected:
workspace1Node1
workspace1Node2
workspace1Node3
But when I am shutting down the repository before retrieving the nodes
(passing true in the call to runTest(boolean)), I am getting unexpected
results:
workspace1Node3
This only happens with the DerbyPersistenceManager. Changing to
FileSystemPersistenceManager gives no problems.
Supplied repository.xml and runnable MultipleWorkspaceTest.java

Re: problem retrieving nodes from different workspaces
Posted by J Kuijpers <ja...@hotmail.com>.
Ok hmm strange... This toppic involves the same problem as the toppic of my
collegue quipere (ItemNotFoundException while switching between different
workspaces). The reason why I am not getting an ItemNotFoundException but
only the wrong nodes, I think is because the code I am using is not using a
NodeType which is orderable. The orginal code does use such a nodetype. When
creating the test class I couldn't use our custom nodetypes. That's the main
difference.
Will supply the class inline:

You're right, that I didn't find that myself. Thanks for spotting it :)

Re: problem retrieving nodes from different workspaces

Your repository.xml file is broken.
You have:
<PersistenceManager
class="org.apache.jackrabbit.core.state.db.DerbyPersistenceManager">
<param name="url"
value="jdbc:derby:${rep.home}/version/db;create=true"/>
<param name="schemaObjectPrefix" value="version_"/>
</PersistenceManager>
A fixed value for the parameter 'schemaObjectPrefix' will cause
Jackrabbit to write content of multiple workspaces into the same
table, thus possibly overwriting content.
You must use a value that includes the workspace name as a variable.
E.g. the sample configuration uses this:
<param name="schemaObjectPrefix" value="${wsp.name}_"/>
See also:
https://svn.apache.org/repos/asf/jackrabbit/trunk/jackrabbit/src/main/config/repository.xml
Using the sample repository.xml the test works fine even with a
shutdown in between.

The MultipleWorkspaceTest.java file appears to be empty. Could you
resend it, inline if necessary?
