Unknown language: XPath
I'm getting that exception when running:
Workspace workspace = session.getWorkspace();
QueryManager queryManager = workspace.getQueryManager();
javax.jcr.query.Query query =
queryManager.createQuery(statement,javax.jcr.query.Query.XPATH);
javax.jcr.query.InvalidQueryException: Unsupported language: xpath
at
org.apache.jackrabbit.core.query.QueryTreeBuilderRegistry.getQueryTreeBuilder
(QueryTreeBuilderRegistry.java:69)
....
Looking at jackrabbit source code, it seems that the line Iterator it =
ServiceRegistry.lookupProviders(QueryTreeBuilder.class); in
QueryTreeBuilderRegistry class is unable to load any BUILDERS.
What I'm missing? Do I have to touch any configuration file to add XPath
support?
Thanks.
Martin

Hi Srinu,
can you please create a jira issue and specify the tomcat version you
are using and also how you deployed jackrabbit? as a resource or
embedded with your web application?
thanks

Hi,
I am having the same problem. I m using the latest jcr jar. In tomcat it is
showing in META-INF/services/

------------------
But when i execute the same query in standalone it is working fine. Can u help
me in this ...
This is the java file i m using to fetch the content
public static void fetchAllContent()
{
try{
Repository repository =
new TransientRepository(CONFIG_FILE, DIRECTORY);
// Login to the default workspace as a dummy user
Session session = repository.login(new SimpleCredentials
("anonymousId", "anonymous".toCharArray()));
// Use the root node as a starting point
Node root = session.getRootNode();
Workspace ws = session.getWorkspace();
QueryManager qm = ws.getQueryManager();
//Specify a query using the XPATH query language
Query q =qm.createQuery("//content", Query.XPATH);
QueryResult res = q.execute();
//Obtain a node iterator
NodeIterator it = res.getNodes();
while (it.hasNext()) {
Node n = it.nextNode();
//Property prop = n.getProperty("blogtitle");
PropertyIterator iter=n.getProperties();
while(iter.hasNext()){
Property prop=iter.nextProperty();
System.out.println(prop.getString());
}
}
session.logout();
} catch (Exception e) {
e.printStackTrace();
}
Thanks in advance.

Marcel I built jackrabbit just now, and .........

it worked !
So, no need to worry :)
Thanks for your help.

Marcel, then I'll build jackrabbit again just today. I'm using a jar file
from two weeks ago. I'll send another messages with the result.
Thanks!

using the service registry is the only way to register query languages.
Some time ago, I had a similar problem when I deployed two jackrabbit
instances in the same jvm. A fix for the QueryTreeBuilderRegistry solved
the issue. the svn revision for that change is: 312874
Your initial mail indicates that you are using an older version, though.
If you know you are using a more recent revision to build your jar file
then I probably have to change the dynamic loading of QueryBuilder
(again) :-/

Re: Unknown language: XPath
Posted by Martin Perez <mp...@gmail.com>.
I have looked inside the jar file and it contains:
META-INF
META-INF/services
META-INF/services/org.apache.jackrabbit.core.query.QueryTreeBuilder
META-INF/services/org.apache.jackrabbit.core.query.TextFilterService
The contents of QueryTreeBuilder file lists:
#
# This file lists all available query language implementations that are
shipped
# with Jackrabbit.
#
org.apache.jackrabbit.core.query.xpath.QueryBuilder
org.apache.jackrabbit.core.query.sql.QueryBuilder
So it seems that all is ok.
I don't know where can be the bug. Maybe it could be that I'm developing an
Eclipse RCP application and Eclipse has its own custom classloader, so it
could be some classloader related issue.
Any suggestions? Is there any other way to specify the languages without
using that ServiceRegistry? Anyone knows why I can't search?
Thanks again.

please make sure that the new file
META-INF/services/org.apache.jackrabbit.core.query.QueryTreeBuilder is
included in the jar file when you build jackrabbit.
if you are using an up-to-date revision of the project.xml, maven should
take care of that.
