Also, do you see anything in derby.log on the server? As for compiling Derby with JDK 1.6: I think i use a plain "xalan.jar", which in addition to xalan-j2-2.7.0 contains some supporting packages, perhaps that is why you have an compile time issue with xpath and serializer. (see http://xml.apache.org/xalan-j/downloads.html). As for the problem with the the abstract method (EmbedDatabaseMetaData), this line in ant.properties is wrong: j14lib=/usr/local/jdk1.6.0_02/jre/lib It should point to the JDK 1.4, not to JDK 1.6, even if you use the 1.6 compiler. (Derby needs to compile some of the sources with a JDK1.4 source level and runtime, in order for the resulting product to be runnable on multiple platform versions). Thanks, Dag
