ocm: is not a registered namespace prefix.

Hi,

I started to use OCM to save object to repository today and got an exception below. It seems that I need to
register a namespace ocm. Can anybody please tell me how to fix it?

org.apache.jackrabbit.ocm.exception.ObjectContentManagerException: Cannot create new node of
type nt:folder from mapped class class com.openandgreen.service.system.Folder; nested exception is
javax.jcr.NamespaceException: ocm: is not a registered namespace prefix.
javax.jcr.NamespaceException: ocm: is not a registered namespace prefix.

Thanks a lot,
Kevin

Strange problem in repository creation

Hi,I am getting following error when I start my tomcat server. I am using
Spring and Hibernate as underlying technology. Following are excerpts from
spring bean configuration:

<bean id="repositoryManagedConnectionFactory"
class="org.apache.jackrabbit.jca.JCAManagedConnectionFactory"
destroy-method="finalize">
<property name="homeDir" value="${user.home}/jackrabbit" />
<property name="configFile" value="classpath:repository.xml" />
</bean>
When the server loads all the spring bean it tries to start jackrabbit
repository and I get this strange error. I am running Tomcat on Windows XP.
This error is coming intermittently so I am bit confused. Please let me know
if anyone had faced similar problems.

Regards,
Anand.

Tomcat 6.0, Hibernate 3.1, Spring 2.5.4, Jackrabbit 1.4

Re: Jackrabbit JCA 1.5 problem on Jboss 4.2.3.GA-jdk6

As I can see in the error trace, perhaps que zip file is corrupted
(java.util.zip.ZipException: invalid stored block lengths). For some reason,
the mvn task could be generating a non-valid zip.

Have you tried to download de JCA rar file from
http://www.apache.org/dyn/closer.cgi/jackrabbit/binaries/jackrabbit-jca-1.5.0.rar?

Re: ocm: is not a registered namespace prefix.

Try

workspace.getNamespaceRegistry().registerNamespace("ocm", "
http://jackrabbit.apache.org/ocm");

Temp File Semantics

We¹ve been testing Jackrabbit for a few months now and are starting to roll
it out into production. We recently noticed that during heavy load temp
files (e.g. - dbRecord12345.tmp) are not getting cleaned up. This occurs
when the temp filesystem fills up and a we get an exception like this:

org.apache.jackrabbit.core.data.DataStoreException: Can not read identifier
240b723f5a9fc1969f8f653382daf6a5aefff5f2: No space left on device: No space
left on device

It seems at this point that Jackrabbit abandons the files and does not make
any attempt to remove them from the temp directory. Obviously, this leaves
the system in an unusable state until we manually purge the temp files.

I assume the files I'm seeing are intended to be transient cache files since
our data store is on a central DB and I don't see any files lingering during
normal operation.

So, I have a few questions:

1 - Can I configure the temp directory used by Jackrabbit? I don't want to
set the temp directory globally, just for Jackrabbit.

2 - Is there a way to recover from this more gracefully and purge the temp
files? Ideally I can wait for space to free up on the device when Jackrabbit
purges other transient files from the temp space.

3 - Why create so many short-lived files? I notice that when the problem
occurs, there are many copies of the exact same file in the temp directory.
It seems more appropriate to keep a single cache file around for a given
item and manage the local cache at a set maximum size using an LRU

Re: ocm: is not a registered namespace prefix.

Hi Todd,

I added your code but got exception

javax.jcr.NamespaceException: failed to register namespace ocm -&amp;gt;
http://jackrabbit.apache.org/ocm: mapping already exists

Any idea?

Thanks a lot,
Kevin

Re: ocm: is not a registered namespace prefix.

You only have to register the namespace once. Perhaps this exception was
thrown on a second run?

Thanks, Todd. You're right. I called more than one time. -Kevin

Extra entry in get file list with jackrabbit webdav


Hi I am a developer at maven wagon.  we use jackrabbit 1.5.0 to list the
content of a webdev directory.
However, the jackrabbit webdav always return an extra entry which is the
directory of the parent

so here is the code

                DavPropertyNameSet nameSet = new DavPropertyNameSet();
                nameSet.add( DavPropertyName.create(
DavConstants.PROPERTY_DISPLAYNAME ) );

                method = new PropFindMethod( url, nameSet,
DavConstants.DEPTH_1 );
                int status = execute( method );
                if ( method.succeeded() )
                {
                    ArrayList dirs = new ArrayList();
                    MultiStatus multiStatus =
method.getResponseBodyAsMultiStatus();

                    for ( int i = 0; i < multiStatus.getResponses().length;
i++ )
                    {

                        MultiStatusResponse response =
multiStatus.getResponses()[i];

                        String entryUrl =  response.getHref();
                        String fileName = PathUtils.filename(
