Hi Dominique,
here's where it really gets strange - I'm also accessing the jackrabbit
repository through my own JSF application using:
InitialContext context = new InitialContext();
Repository repository = (Repository)
context.lookup("java:jcr/local");
SimpleCredentials credentials = new
SimpleCredentials(username, password.toCharArray());
Session session = repository.login(credentials);
and subsequent operations on the repository in this session work without
any problems.
Then I have an EJB (3.0, SLSB) with the following code:
InitialContext ctx = new InitialContext();
Repository repo = (Repository)ctx.lookup("java:jcr/local");
Credentials cred = new SimpleCredentials(path.getUsername(),
path.getPassword());
Session session = repo.login(cred, null);
and here subsequent calls bring up the reported problems.
Do you have any idea what is wrong in the EJB (or what I could try
alternatively - Do I have to add certain annotations regarding CMT?)?
many thanks,
Markus

Hi Markus,
I don't know whether your client code resides in a servlet or EJB, but
this is what I did to access the repository from a sample JSP page
containing the following code snippet:
InitialContext ctx = new InitialContext();
Repository repository = (Repository)
ctx.lookup("java:comp/env/jcr/repository");
(1) inside the web application's web.xml file I declared the reference:
<resource-ref>
<description>Jackrabbit</description>
<res-ref-name>jcr/repository</res-ref-name>
<res-type>javax.jcr.Repository</res-type>
<res-auth>Container</res-auth>
</resource-ref>
(2) inside the web application's jboss-web.xml file I linked the reference to
the actual datasource:
<resource-ref>
<res-ref-name>jcr/repository</res-ref-name>
<res-type>javax.jcr.Repository</res-type>
<jndi-name>java:jcr/local</jndi-name>
</resource-ref>
As far as I can tell - I'm not a JBoss expert - the exception in that
other post is caused by accessing the global data source directly
instead of declaring a reference to it in the web application
descriptor.

Hi Dominique,
that's exactly what I expected as well - however if I execute the code
as is (i.e. without the surrounding XA stuff), I get an exception that
tells me that no transaction has been started (STATUS_NO_TRANSACTION) -
my exception is very similar to what has been reported at
http://mail-archives.apache.org/mod_mbox/jackrabbit-dev/200702.mbox/[EMAIL
PROTECTED]
Therefore I tried to start the transaction myself ...
... any further help/guidance/hints is/are highly appreciated ...
kind regards,
Markus

Hi Markus,
Apparently, your session is already associated with a transaction. I
don't unterstand why you'd want to access the XAResource directly in
your client code. I'd expect that if you left only your core code
(starting with the comment "// .... add new nodes & properties and
save them") JBoss would automatically execute the surrounding code you
inserted manually.
Kind regards

Dear All,
I'm currently playing around with Jackrabbit's jca package and end up in
some strange errors (which will mainly be due to wrong use from my code
:-)). Here's my environment:
JBoss 4.0.5.GA
Java 1.5_06
Jackrabbit 1.3.1 (checked out and build tagged version)
jcr-ds.xml (only modified homeDir property - I experimented with both
true and false for bindSessionToTransaction):
<connection-factories>
<tx-connection-factory>
<jndi-name>jcr/local</jndi-name>
<xa-transaction/>
<rar-name>jackrabbit-jca-1.3.1.rar</rar-name>
<connection-definition>javax.jcr.Repository</connection-definition>
<config-property name="homeDir"
type="java.lang.String">${jboss.server.data.dir}${/}jackrabbit</config-property>
<config-property name="configFile"
type="java.lang.String">classpath:repository.xml</config-property>
<config-property name="bindSessionToTransaction"
type="java.lang.Boolean">false</config-property>
</tx-connection-factory>
</connection-factories>
Here's my client code:
XAResource xares =
((JCASessionHandle)session).getManagedConnection().getXAResource();
//xares is either of type org.apache.jackrabbit.core.XASessionImpl (if
bindSessionToTransaction is set to false and
org.apache.jackrabbit.jca.TransactionBoundXAResource if set to true)
// create dummy Xid
Xid xid = new XidImpl(counter++); //XidImpl is simply copied from
org.apache.jackrabbit.core.UserTransactionImpl
((org.apache.jackrabbit.core.XASessionImpl)xares).associate(null);
//I think I shouldn't do that :-)
xares.start(xid, XAResource.TMNOFLAGS);
// .... add new nodes & properties and save them
Node root = session.getRootNode();
Node child = root.hasNode(path.getRelativePath()) ?
root.getNode(path.getRelativePath()) : createFilePath(root,
path.getPathParts(), path.getObjectName());
FileTypeResolver ftr = FileTypeResolver.instantiate();
child.setProperty("jcr:mimeType", ftr.getMIMEType(obj));
child.setProperty("jcr:data", new FileInputStream(obj));
Calendar rightNow = Calendar.getInstance();
child.setProperty("jcr:lastModified", rightNow);
//child.setProperty("original-file-name", obj.getName());
session.save();
xares.end(xid, XAResource.TMSUCCESS);
xares.prepare(xid);
xares.commit(xid, false);
If I set bindSessionToTransaction to false and disassociate the
XAResource from it's transaction (calling associate(null)), I can start
(and end and commit) the transaction successfully - I have however the
strong feeling that I shouldn't do that :-)
If I set bindSessionToTransaction to true (which would be the default)
or if I do not disassociate the XAResource from it's transaction then I
always get an exception thrown at XASessionImpl line 227 (remember that
I'm working on 1.3.1).
I never found out why the XAResource was associated with a transaction
although bindSessionToTransaction was set to false.
It would be great if someone could tell me what I'm doing wrong and/or
point me to sample code that should work in my environment and/or tell
me if she/he already did something similar successfully when deployed on
JBoss.
many thanks,
Markus
