---------------------------------------
Thanx for your answer.
We have simply deployed the jackrabbit-1.4.6.rar file in our weblogic server
via the administration console.
We have made some adjustment to the standard weblogic-ra.xml file :
<weblogic-connector xmlns="http://www.bea.com/ns/weblogic/90";>
<jndi-name>jackrabbitRA</jndi-name>
<enable-access-outside-app>true</enable-access-outside-app>
<enable-global-access-to-classes>true</enable-global-access-to-classes>

<connection-instance>

<connection-properties>

<max-capacity>200</max-capacity>
<capacity-increment>1</capacity-increment>
<shrinking-enabled>true</shrinking-enabled>
<shrink-frequency-seconds>60</shrink-frequency-seconds>
</pool-params>
<properties>
<property>

<value>...</value>
</property>
</properties>
</connection-properties>
</connection-instance>
</connection-definition-group>
</outbound-resource-adapter>
</weblogic-connector>
And here is our ra.xml file :
<connector xmlns="http://java.sun.com/xml/ns/j2ee";

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

</connector>
Any help will be greatly appreciated.

> URL: https://issues.apache.org/jira/browse/JCR-1938
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-jca
> Affects Versions: core 1.4.6
> Environment: BEA JRockit 1.5.0_06 - Weblogic 9.2
> Reporter: Francois Masurel
>
> Hello,
> We have some deadlock issues with jackrabbit 1.4.6 under weblogic 9.2.
> It seems to happen when the connection pool has reached the maximum
> connections allowed.
> We have to restart weblogic to resolve the problem, it's a bit annoying.
> Actually used on our intranet, we plan to use our CMS solution based on
> jackrabbit on an important public administration internet portal but this
> problem is a showstopper for us.
> Is it a bug ? Did we miss something in our jackrabbit/weblogic configuration
> ?
> Thanx for your help.
