The compiled handle.jar file is available at https://release.prosentient.com.au/handle62/handle.jar.gz It can be used to replace the handle-6.2.jar reference in the dspace 6.4 build or copied directly to the target directly to the target directories - particularly of course lib
./lib/handle-6.2.jar ./webapps/jspui/WEB-INF/lib/handle-6.2.jar ./webapps/xmlui/WEB-INF/lib/handle-6.2.jar ./webapps/swordv2/WEB-INF/lib/handle-6.2.jar ./webapps/rdf/WEB-INF/lib/handle-6.2.jar ./webapps/rest/WEB-INF/lib/handle-6.2.jar ./webapps/sword/WEB-INF/lib/handle-6.2.jar ./webapps/oai/WEB-INF/lib/handle-6.2.jar I have shared the build source at https://release.prosentient.com.au/handle62/handle6.2patched.tar.gz The base is hdl 6.2.05 code from handle.net Note that this does not contain the cnriutil references. I compiled lib/cnriutil.jar derived from the classes in the dspace version of handle-6.2.jar To achieve a distribution I modified the build.xml to remove references to the admintools. I'm guessing this must have been done before with the dspace distro. I modified ./net/handle/server/Main.java to remove System.runFinalizersOnExit(true); Further work could be done to replace this with an alternative code Runtime.addShutdownHook(new Runnable() { public void run(){ // do whatever handle.net needs to exit cleaning on error(); } }); However I have tested the above simple change successfully in an updated ubuntu server running the dspace handle resolver. Not tested for long term service operation, so there is a risk the above change might lead to some memory leakage. However the fact that the handle service runs seperately makes it easy to monitor. The build process is: ant clean ant server ant distjar The build output is in the dist folder Hope this helps.
