NetRexx Install question

Hi,

I'm trying to install NetRexx on my z/os machine. When I tried to compile the "hello" sample, this is what I got:

EDH:/Z113/usr/lpp/java/examples/ibm-historic: >java org.netrexx.process.NetRexxC

hello

NetRexx portable processor, version NetRexx 3.01RC3, build 21-20120806-0031

Parts Copyright (c) IBM Corporation, 1995,2008.

I'm running z/os 1.13 and IBM Java 6.0.1 64-bit.

I guess there is something missing from my CLASSPATH, but I don't know what that is. Any help?

Re: NetRexx Install question

Earl, looks like you have the 1.6 JRE. You need the 1.6 SDK . It’s looking for tools.jar.

You’ll also want the SDK because it has things like the jar command that you’ll want going forward.

Just thinking aloud... going forward.... isn´t there a way to make
NetRexx check if the system requirements are met the first time it
runs ie "hey! I detected you have the JRE, you need the JDK (Java
development kit). Get it from here: (URL based on detected OS, from an
internal table).

To avoid broken links, the internally stored urls could be
http://netrexx.org/get/jdk/os/name
which would be automatic redirectors that can be dinamically changed as needed.

Just my $0.02

Re: NetRexx Install question

In reply to this post by measel

This is one of the cases in which you can use the ecj-4.2.jar Java
compiler that has been included with NetRexx 3.01RC3. Put it somewhere
(in the same directory as NetRexxC.jar - binary upload just like
NetRexxC.jar) and make sure it is on the classpath. Then add
-Dnrx.compiler=ecj to the NetRexxC.sh script on the line that says java
org.netrexx.process.NetRexxC, between java and
org.netrexx.process.NetRexxC .

Of course, installing the SDK also works - but this might not be the
easier solution on a mainframe. NetRexx is able to run on a JRE system,
interpreting and compiling code, nowadays.

best regards,

René.

And this is due entirely to René's hard work and dedication. He'll
never take credit for it, so we must all give a round of applause on his
behalf. <muted clapping>

Re: NetRexx Install question

In reply to this post by Fernando Cassia-2

Fernando,

two things:

1 - we are certainly going to add something like that to the installer
- I agree with Bill's point of view that we should not bother the
NetRexx translator itself with platform knowledge
2 - there is no requirement for the JDK anymore, starting from 3.01, a
JRE will suffice. There is, however, plenty of opportunity for other
classpath problems.

best regards,

René.

Very very nice. I remember you once talked about "generating bytecode
directly" and I thought to myself "WTF? why mess with MFC´s design of
generating java source and passing it on to the latest greatest JDK
compiler?".

Of course, I didn´t had in mind the ´minor detail´ of a mainframe user
not being able to install the JDK....

Thanks for adding that feature then, I figure now that it makes sense. :)

Re: NetRexx Install question

In reply to this post by measel

But Mike, I wonder how you can see that Earl has the JRE only. It might
be just missing the tools.jar on the classpath.
My classpath is like
/opt/ibm/java-s390x-60/lib/tools.jar:/opt/ibm/java-s390x-60/jre/lib/s390x/default/jclSC160/vm.jar

note that it needs both tools.jar and vm.jar with IBM's Java because
otherwise your next error would be Object.class not found.

Anyway, Earls previous error should be solvable by adding ecj.

best regards,

René.

It´s not a matter of fine-grained ´platform knowledge´ just catchng
the three most common platforms (windows, linux, mac os x) and
providing instead of a generic message, a less-intimidating pointer
about the location of the jdk or jre or whatever add-on that the user
might need.

If os=not_on_the_list_of_known_OSs_with_friendly_error_messages then
print Standard_confusing_message

In the end it´s self-interest to save us all from newbies that come
here crying saying "I just downloaded NetRexx but I can´t run it, it
spits this long ugly error message

...followed by the long ugly error message .

Re: NetRexx Install question

In reply to this post by Fernando Cassia-2

Yes, and when reading through the source, for the interpreter part it
is generating the bytecode already.
I added the JRE only feature out of necessity, it also works on Windows
and Linux in locations where you might not be admin enough to install
things - and it is less disruptive than trying to change which of many
JVM's on a given machine in the case you are admin.

I am looking forward to the 3.02 release in which we will try to quell
the install problems once and for all.

best regards,

René.

Re: NetRexx Install question

Problem is, these change all the time. I think putting it in the
installer, with an optional, online database, would be optimal. NetRexx
already knows some Mac and z/Linux paths, but I was planning to take
that out because both have changed already.

BTW, my answer was blocked for some users due to your 'pornographic
expression' in the original post - see if you can guess. It was an
expression of wonder or puzzlement that every 11 year old tweets at
least twice a day. What has the world come to.

Re: NetRexx Install question

In reply to this post by rvjansen

Seldom would I argue with Rene but if you're going to do anything more serious than hello world you're gonna want the SDK.

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

And if you want to do any real work on MVS (read a vsam file for instance) then you'll need Zee extensions.

If you're an OMVS user check out BPXBATCH. Lets you fire up your NetRexx in BATCH !! YEAH BABY.

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?]

Re: NetRexx Install question

Hard to believe I'm going to argue with Mike and Rene today... oh well.

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.

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?]
