Re: NetRexx Install question

To quote the new Quick Start Guide(p. viii):

For serious development purposes a Java SDK is recommended, as the tools found therein might assist the development process.

So no contest here. It is just sometimes hard to have something extra on the mainframe when you're not the sysprog.

Ok, but, many of the free tools don't exist for USS/OMVS. Even the tools that are there were developed by some AIX guys on crack.

As for jar command, my favorite is to add my classes to the NetrexxR.jar and have a nice little package I can drop anywhere without dependencies. This also keeps my users from having to install or configure anything.

Simplicity.

And, when you want to build packages like the big boys, you gotta jar. I can create a servlet in NetRexx and package it correctly and give it to my websphere guy who won't know it's not a "real" java application.

Just one example - the jar command, which is absolutely
necessary to examine a jar in the absence of winzip.

Not really -- it's just a zipped file, so any of the free zip tools will do, as
will the zip file processor included in Windows.

[But why would one want to inspect the contents of a .jar file anyway, unles
debugging a .jar file builder or or a zip.exe?]

Exactly, hence my idea of all he hard-coded URLs to be actually
redirectors, hosted on the netrexx site. So when these urls change,
Netrexx admins only need to update the web site redirectors, not the
hard-coded URLs in the code.

Think of it like http://tinyurl.com but hosted on netrexx.org. There´s
plenty of redirector scripts out there that you could use.

Thanks, Rene, for refreshing my brain ...

... probably simply a memory overflow flipping between too many Computer
Languages,
at the minute, at least.

Slow progress with learning SVN, and preparing first release to Kenaiy,
however...
(That's the good part of the news...)

Tom, all:

May I join you in applauding to Rene! :-)

Mr. RexxLA President, *excellent work* (as always)...

Thanks a lot for all the time you did invest to make this happen!
Thomas.

PS: And sorry I did ask again too quickly .... Maybe I'm already getting
too old ?

Actually, I think, however, that it seems to depend whith my working
style ...

When reading and answering mails,I'm sticking with mail when a quetion
(for me) does
arise, and am not used to open another window with WikiPedia and/or
Google...

... might depedn that when I started using computers we didn't even have
screens?

But: I will *try* to improve :-) Beg your pardon, anyway!
... and: thanks for answering!

That doesn't wash, Thomas. I also started by sitting at a keypunch --
as I think many members of this list have done. Not beginning with a
screen in front of you does not explain your failure to keep up.

Try again.

Tom.

Re: NetRexx Install question

Will do, Tom, for sure...

Will now, *before I do ask questions*, Consult Mr. Google and Mrs.
Wikipedia...

Don't actually want *to waste your time* :-)

Thanks for both hints.

Thomas.
