== Common problems when using / building the contrib jcr-server ==

 * Follow the build instructions in the jackrabbit/contrib/README.txt

 * Jackrabbit depends on a "newer" JAXP version than say JDK-1.4.2 is shipped with. Xerces 2.6.1 works. Since the xml jars are "endorsed" (javax.xml...) you should place them in $JAVA_HOME/jre/lib/ext. If using tomcat you can place the xerces jars in $CATALINA_HOME/common/endorsed

 * You must add the system property java.security.auth.login.config to point to a jaas configuration file. Use the file jackrabbit/application/test/jaas.config. In tomcat copy the file to $CATALINA_HOME/conf, and add the following -Djava.security.auth.login.config=%CATALINA_HOME%/conf/jaas.conf to the environment var CATALINA_OPTS. (If your tomcat is already using jaas, simply merge the content of jaas.config with the file that tomcat uses

TODO : add a list of the exceptions thrown, when running without the prober xml api versions, since you must be psychic to figure out that out your self.
