The simplest explanation is probably the correct one: it is not on the classpath. This class is to be found in the jersey-server-1.3.jar is that jar on the classpath? (or in jersey-client-1.3.jar, either will do) The simplest way one might be fooled into not including it in the classpath is due

You'd have to do the filtering/pruning in an evaluator, but the sub-pathing afterwards, like: for ( Path path : description.traverse(...) ) { path = subPath( path, 2 ); } private Path subPath( Path source, int from ) { if ( source.length() from )

The failures you are seeing are for tests that deal with large data. They thus need a large heap configuration to succeed. For specifying such settings for maven you would use the MAVEN_OPTS environment variable, something like: export MAVEN_OPTS=-Xmx1G Cheers, Tobias On Thu, Apr 7, 2011 at
