Separate eXist db configuration

[lazx ()]

*Extending the discussion from this thread: http://www.nabble.com/Data-lost-on-%22Save-Document%22-td18389797.html   to this one.*


I am attempting to configure orbeon to use an eXist database running in a separate tomcat instance (eventually a separate server).

orbeon: localhost:8083
eXist: localhost:8081

eXist cache connection is working with the following config:

    <property as="xs:anyURI"  name="oxf.xforms.store.application.uri"                value="xmldb:exist://localhost:8081/eXist-1.2.3-rev7866/xmlrpc"/>
    <property as="xs:string"  name="oxf.xforms.store.application.collection"         value="/db/orbeon/xforms/cache/"/>


But the following does not work for the storage connection:

    <property as="xs:anyURI"  name="oxf.fr.persistence.service.exist.uri"            value="/eXist-1.2.3-rev7866/rest/db"/>
    <property as="xs:anyURI"  name="oxf.fr.appserver.uri"                            value="http://localhost:8081"/>


Error log (browser):

Fatal error: Premature end of file.


Error log (orbeon.log):

This occurs when I click "New Form" in the Form Builder

Try to change this to (this should point to your eXist database):

http://localhost:8081/orbeon/exist/rest/db

>    <property as="xs:anyURI"  name="oxf.fr.appserver.uri"

Leave this set to "" (empty). You only need to change this when you
have a special situation with a proxy in front of Tomcat/Orbeon Forms
which itself cannot be accessed by the machine on which Tomcat/Orbeon
Forms runs.

You'll let us know how this works for you.

Thanks Alessandro,

That did the trick!

Will start testing out that deadlock problem :)  (aka if separating exist and orbeon into separate tomcat instances works).

Re the deadlock problem

Have you tried to get a thread dump of the running tomcat process

If you are running on unix:
 kill -SIGQUIT <pid of tomcat>
(it doesnt actually quit just dumps the trace)
The dump goes to the logfile catalina.out (in my case)

I imagine that on windows you could execute "catalina.bat run" and
type Ctrl-Break to get the dump

The best would be to do several in succession to see what changes.

That might help to track down what is going on.

Let us know how you get on

And on unixish systems, a ctrl-\ does the same as ctrl-break on
Windows (assuming you have java running in a terminal).
