Has anyone seen any documentation behind the cubes on the Proven_Techniques server? I can reverse engineer to see what they've done but having a little documentation as a head start would be nice.Michel Zijlema wrote:New samples are available
The Proven Techniques is a new sample database that installed by default. The GO_Scorecards sample database is also now installed by default.
Yes. But even more, the Java code has access to all of the same functions that a TI process does, plus a few more to enable the same logic that occurs when moving from Prolog -> Metadata -> Data -> Epilog.Plunge pool wrote:Alan Kirk wrote:Thanks for that.

So stupid question....does this mean that a TI Process can call and run a Java application? Is that what I am hearing?
Well, we have Java, anyway.dr.nybble wrote:So you now have a "real" language to program in
Yes, you can now call java functions in TI. We were able to use Eclipse during the beta to create callable Java classes. They basically work like your existing TI functions but there is a special prefix when referencing them. Things like cleaning up special characters, string searching, etc. can be easier to do in Java. Plus Java opens up a quite a lot of capability such as interfacing with Cognos BI through the SDK or other Web Services etc.Plunge pool wrote:So stupid question....does this mean that a TI Process can call and run a Java application?

It's not free (nor is it horrendously expensive), but if you're looking for "from the ground up" training it's hard to go past Lynda.com. The best part of it is that there are different levels of courses in most topics as well as a few specialist sub-courses, so you can cherry pick what you need. Java is no exception to this. If you're really completely new to Java it's worth getting the Premium subscription which includes source files so that you don't have to write all of the code from scratch as you follow along. You can subscribe either by month or year.Steve Rowe wrote:Not at all familiar with Java, anyone got any pointers to good training?
How can there be, it's "write once, debug everywhere", remember? Every implementation of Java uniformly tastes like pi... er, I mean, like American beer.Steve Rowe wrote: Are there multiple flavours of Java?
Because it's a cr@p language for anyone who works primarily in Windows. The case sensitivity is a pain in the @$$. The endless sea of braces are nothing more than syntax errors waiting to happen which get in the way of you getting from point A to point B in the fastest possible time. It doesn't dovetail neatly into Excel. Don't even get me started on how painful writing a decent GUI is compared to .Net. The stupidity of the Switch Case syntax with the need to explicitly Break once you have a match is brain dead and another bug-waiting-to-happen, though at least Java 7 finally let you use the thing with strings. (Yes, I'm aware that this is a hangover from C languages. It remains a stupid piece of language design, whatever its provenance.) It's slow, as anyone who's seriously contemplated slamming their head into a wall while waiting for Performance Muddler to load can attest despite highly dubious claims that "Oh yeah, Java is as fast as machine code now". It's security leak prone to the point that there are still security experts who say "If you don't need Java, don't install Java". Cheezes, for once even Apple and I agree on something, with them having dumped the inclusion of the JRE in Lion, which I doubt was done for no particular reason.upali wrote:Being someone who works primarily on Java and TM1, I couldn't be more excited with the ability to finally put the Java API to good use. I just don't get it why there is so much Java bashing here...
