Hi, I am trying to use BaseX JAX-RX embedded, e.g. start it from my desktop application when the user clicks "Open App" in the system tray menu. The server starts up fine, but when I try to send it a query the Jersey server generates an error, see the log below after the user clicks "Open App". ================================================================================================ 7-jul-2011 16:25:01 com.sun.jersey.api.core.PackagesResourceConfig init INFO: Scanning for root resource and provider classes in the packages: org.jaxrx.resource 7-jul-2011 16:25:02 com.sun.jersey.api.core.ScanningResourceConfig logClasses INFO: Root resource classes found: class org.jaxrx.resource.XMLResource class org.jaxrx.resource.JaxRxResource 7-jul-2011 16:25:02 com.sun.jersey.api.core.ScanningResourceConfig init INFO: No provider classes found. 7-jul-2011 16:25:02 com.sun.jersey.server.impl.application.WebApplicationImpl _initiate INFO: Initiating Jersey application, version 'Jersey: 1.6 03/25/2011 01:14 PM' 7-jul-2011 16:25:03 com.sun.jersey.spi.container.ContainerResponse write SEVERE: A message body writer for Java class org.basex.api.jaxrx.BXJaxRx$2, and Java type class org.basex.api.jaxrx.BXJaxRx$2, and MIME media type text/xml; omit-xml-declaration=no was not found 7-jul-2011 16:25:03 com.sun.jersey.spi.container.ContainerResponse write SEVERE: The registered message body writers compatible with the MIME media type are: */* -> com.sun.jersey.server.impl.template.ViewableMessageBodyWriter

I already tried removing the "; omit-xml-declaration=no" but that didn't help. Any ideas on why this does not work? Hartelijke groet, Huib Verweij.

Huib, unfortunately, as far as I know, no one in our team managed to reproduce your problem. Do you have some more step-by-step details what you did (which BaseX version/OS/etc you used)? Christian

Sure, of course. I work on Mac OS X Snow Leopard, Java version 1.6.0_26. I am using BaseX 6.7.1-SNAPSHOT, just updated. In my code I have this method that starts the JaxRxServer, it is called when a menu option is selected by the user.:
    // Start the database.
    protected static Boolean startDb() {
        db = new JaxRxServer();
        return true;
    }
When the database has started a webserver is started next. At the index.html webpage a user can login, which causes a request to the db over the JAX-RX interface. At that point I get the reported error. If you need more info let me know! Hartelijke groet, Huib Verweij.

Written for BaseX 6.7. BaseX may have changed since: please check the current documentation.
