The behaviour is similar also for the report http://wiki.openkm.com/images/6/67/Subs ... ents.jrxml

Not all 5.x reports are compatible with OpenKM 6.x ( I think you're using 5.x under 6.x ), confirm to me.

I downloaded the sample reports from http://wiki.openkm.com/index.php/Reports
I tried also the parametric one (with .rep extension)
but also this one gives:

Code: Select all

Sourced file: inline evaluation of: ``import javax.jcr.*; import javax.jcr.util.*; import org.apache.jackrabbit.*; imp . . . '' : Typed variable declaration : Attempt to resolve method: getSystemSession() on undefined variable or class name: DirectRepositoryModule

when executed.
Maybe it should be specified in the wiki that the samples works only with version 5.x and lower..
There is some example for version 6.x?
What is the source of the problem here?

Thanks.

I corrected to indicate that 5.x reports will not be executed under 6.x. I have oppened the tree first reports in wiki, in few days - when I got some extra time - will be all available without restrictions ( to change security restrictions I need some time ).

Hi wonderful OpenKM people!

In OpenKM 5.x I make extensive use of reports based on XPath queries.
Now OpenKM 6.x doesn't use Jackrabbit any more, so my scripts for executing XPath query doesn't work in version 6.x

The simplest example is your own example in the Wiki: http://wiki.openkm.com/index.php/Reports#XPath_Report

The important part is this:

Code: Select all

Session jcrSession = DirectRepositoryModule.getSystemSession();
Workspace workspace = jcrSession.getWorkspace();
QueryManager queryManager = workspace.getQueryManager();
Query query = queryManager.createQuery(statement, type);
QueryResult result = query.execute();

Please show me how to translate this to version 6.x ?

Thanks very much

Here http://wiki.openkm.com/index.php/Utilities you can got actual basic report templates, in your case you should modify java.

To get administration privileges to should use systemToken not session

Code: Select all

String systemToken = DbSessionManager.getInstance().getSystemToken();

And always use query API ( like you can see in examples jrxml in the url )

Code: Select all

Map<String, String> properties = new HashMap<String, String>();
properties.put("okp:test.name", "some_value");
QueryParams queryParams = new QueryParams();
queryParams.setDomain(QueryParams.DOCUMENT);
queryParams.setProperties(properties);
Collection<QueryResult> results = OKMSearch.getInstance().find(null, queryParams);

Here can navigate across actual classes http://doxygen.openkm.com/6.2.x/

For your information I have pending task from last year that's make some video about how reports should be done.

Hi thanks a lot for your reply.

In the new query API, is there a class which lets me run an XPath or SQL statement directly?
I did it in my OpenKM 5.x reports as follows:

Code: Select all

Query query = queryManager.createQuery(statement, type);
QueryResult result = query.execute();

where "type" is "xpath" or "sql",
and "statement" is the full SQL statement or XPath query string.

In OpenKM 5.x I have some beautiful (but complex) reports to retrieve metadata values,
and I'd like to re-use them again in version 6.x

Or is there another way to retrieve metadata values?

Thanks once again

You should take a look at actual SearchServlet.class
http://doxygen.openkm.com/6.2.x/db/d1c/ ... rvlet.html in this detailed description (http://doxygen.openkm.com/6.2.x/db/d1c/ ... rvlet.html) you can get full source code.

Actually all queries should be done with database structure ( althought you'll xpath will not be reusable at 6.x on future you'll see the actual database structure is more easy to be used to extract information ).
