Hi. I followed the instructions in the docs to enable the resolver.jar as a lib. I edited the various executables in the bin directory, but still the GUI to create a new database does not enable the options to define a catalog file. Resolver.jar is copied in lib folder and my basexserver file is as follows: #!/bin/bash # Path to this script PWD=`dirname $0` # Paths to distributed files or source directories BASEX=$PWD/../BaseX.jar # Options for virtual machine VM=-Xmx512m # Classpath LIB=$PWD/../lib CP=$BASEX:$LIB/lucene-analyzers-3.0.2.jar:$LIB/tagsoup-1.2.jar:$LIB/snowball.jar:$LIB/resolver.jar # Run code java -cp "$BASEX" $VM org.basex.BaseXServer "$@" I have done the same to my basexgui as well, but to no avail. I am very new to XML concepts such as namespace. Thanks Loke
