JDO && OJB
Are there any advanced tutorials for JDOQL available? Or has someone some links to good resources about JDOQL?

Can anybody give me a hint how to successful load the repository.xml from a jar-file? As Charles Harvey just pointed out, if your are using a repository with a HTTP dtd-declaration the XML-parses might try Internet access to get the DTD. What you want is this: And to make sure repository.dtd is in the CLASSPATH. OJB error-reporting should definately be improved here, it was way too complicated to get to the point... Thanks for your help, When the dtd is in the jar also (in the same directory) then it works. For convinience my setup is a standalone Excalibur server. No tomcat (webapp) nor J2EE container. I'm using simply Excalibur and Avalon. When specifying then ConnectionFactoryManagedImpl then each and every connection attempt is going through the factory? I tried with an own ConnectionFactory implementation and that needs a jdbc-connection-descriptor in the repository.xml. I was looking for a way around specifying two points where I have to put database connecton definitions. One for the avalon pool and one for OJB. I decided to drop the avalon one now.

Without going into the re-use issue I can just report that there is no problem placing the different repository*.xml files in a JAR. Just make sure the DTD is there to make XML-validation possible.

Excalibur Integration
Hi, is there a way to reuse existing connections for the whole OJB setup? I've implemented a ConnectionFactory for OJB as Excalibur component, but when I create a new database and open it (as stated in the tutorials) the repository_database.xml part is always expected. Are there any workarounds? (Best would be a complete reuse of existing connections without having to specify a repository_database.xml) Or maybe is there some way to put the repository_database.xml in a jar-file (which is possible for the entiry repository.xml but only for the whole file...)

Re: ojbdoclet and empty result files again
Could you please post the relevant part of the Feature class? Also, you could try running Maven in verbose or debug mode (I don't know anything about Maven, with Ant you would run it with the -v or -debug options). I found my mistake. I've written @obj.class instead of @ojb.class in the doclet-tag. Sorry for inconvinience...

ojbdoclet and empty result files again
Hi users, I want to evaluate OJB for my project and have setup successfully (I think so) a maven task. All classes could be found and everything seems to run fine, but the result files (repository_user.xml) are empty... Anything I miss here? (See the post below are my maven goal definitions and console output) I searched the mailing list before posting here and found a posting very close to my problem, but that was not solving mine. :-( [snip maven.xml] name="provide-ojb-meta" description="Parse ojb meta data and generate ojb files"> name="ojbdoclet" classname="xdoclet.modules.ojb.OjbDocletTask" > [/snip] [snip console-output] Generating ojb repository descriptor (repository_user.xml) Type de.esw.services.server.ojb.Feature Processed 1 types Processed 1 types [/snip] Any idea what could be wrong?
