Ok, I've got a Model 2 devlopement setup of Jackrabbit running in my Tomcat 5.5 server. I would now like to write a small bit of Java code to checkin/out a file and maybe display a little tree view of the asset tree in Swing, any examples out there to simulate a remote client? Do I use RMI?

I'm not sure, I haven't tested it but I guess you would get a ClassNotFoundException if you try this configuration. AFAIK if you define a shared resource the shared jars must be placed under ${TOMCAT_HOME}/common/lib or any common path, see ${TOMCAT_HOME}/conf/catalina.properties#common.loader. The idea behind a shared resource is that no webapp need to know anything about the concrete implementation. Moreover in the scenario you are describing the correct behavior of your webapps would depend in the order in which the web applications are accessed, which doesn't seem to be a good option. br, edgar ps, it's pretty much the same with other embedded resources. e.g. http://www-128.ibm.com/developerworks/db2/library/techarticle/dm-0508bad er/ (The enterprise scenario) http://db.apache.org/derby/integrate/DerbyTomcat5512JPetStor.html > thanks a lot in advance, > > ./alex > -- > .w( the_mindstorm )p. > > > > > > [1] > http://incubator.apache.org/jackrabbit/doc/arch/deploy/howto-model2.ht > ml >
