Hi Folx, we had a number of discussions on how to jumpstart the Java language bindings. Let me recap the status of the Java implementation efforts: - Graeme Pound at OMII-UK started on a (complete) Java implementation, but left OMII> The effort is resting, the last version of his work is available at http://argos.e-science.soton.ac.uk/blogs/GeodiseSAGA/ - OMII-UK is funding a (somplete) Java implementation at LSU/VU, which will tentatively (!) start around April - Malcolm Illingworth and colleques at EPCC and the DEISA project have a Java implementation covering Jobs and Files, which is in use (probably the most progressed implementation to date). http://www.ogf.org/OGF19/materials/501/SAGA-DEISA.ppt - Pascal Kleijer from Naregi Japan started another partial implementation, focusing on Jobs, which has some Naregi specifica http://www.ogf.org/OGF19/materials/501/SAGA-Java-NAREGI.ppt - Lately, Gregor Pipan from XLab started, in the frame of the XtreemOS project, to implement the SAGA Job package. Now, the Java bindings in all these implementations are diverging, and we urgently need to synchronize them. Also, If I understand that correctly, all bindings are by now incomplete (mostly by design, focusing on jobs and files), and none is implementing the task model. Also, other parts of the SAGA look and feel (session, monitoring etc) seem mostly missing. As far as I understood the Java speach from earlier discussions, it should be possible to define the Java bindings as a set of Java interfaces and Java abstract classes, which can potentially be used by all implementations. I would propose to procede as follows: - I created a CVS directory for the language bindings (SAGA-RG/SAGA-Bindings) - I added a version of the OMII-UK package from Greame, as zip. (Could someone with Java knowledge please extract those files which are of real interest, and add just those?) - all other implementations listed above should also add their bindings, in whatever format available. -> That should allow us to compare the existing approaches. - Next we should add a normative version, either starting from the version most people like, or starting from scratch. It would be nice if someone (or better more than one actually) would volonteer to lead that project - preferably someone knowledgeable and interested in Java ;-) CVS details are to be found at: http://wiki.cct.lsu.edu/saga/space/CVS+Details If you don't have a CVS login, or don't receive CVS notification emails, please let me know. One final note: one thing we learned while implementing SAGA in C++ is that, although the API is simple, its implementation often is not. That is by design! It is tough, but please try to keep the API (as in language binding) simple, even if that means that the implementation is getting more difficult.... :-) Also, please think of Java newbies as end users, not of Java experts: the target user group are scientists, not computer scientists :-) Cheers, Andre. PS.: Steven: Grames blog has links to his bindings, but the links are dead. I only have an old version of his. Are you able to dig out his latest package (0.4.1)? -- "So much time, so little to do..." -- Garfield
