 |
|
Hi,
With NetBeans Ruby 6.5, you do not need to have a JDK installed on your
system in order to install and use the IDE. All of the systems that I
use to test the NetBeans Ruby docs (Kubuntu, Mac, and Windows) have JDK
installations.
I am looking for someone who is using NetBeans Rub 6.5 and who does not
have any JDK installations on their system. If you do, and are willing
to answer some questions for me, please contact me.
Thanks,
Chris

You mean that JRE is enough or that there is something in the installer
which trigger installation of JRE/JDK if none of them is present on the
system?
BTW, I think that Erno told me (or might be here on the list or in some
issue), that some part of, mmm.... Glassfish deployment?, really do not
remember... needs JDK, not JRE only. Erno it is still true? If yes,
there should be a wiki telling what part of NetBeans Ruby needs JDK for
its functionality.

Yes, the jar command, which isn't part of JRE, is needed by Warbler for
creating .war files. The Rails wizard should display a warning when the
user chooses to install Warbler when using JRE, I filed
http://www.netbeans.org/issues/show_bug.cgi?id=144815 for that. It
should be a somewhat uncommon scenario though since Java app servers in
general need JDK, and the reason for installing warbler is to be able to
deploy to app servers.

Here is an excerpt from the download page:
| Quote: | Java 6 or Java 5 is required for installing and running the PHP, Ruby and C/C++ NetBeans Bundles. You can download the latest Java 6 Update 7 at java.com.
JDK 6 or JDK 5.0 is required for installing and running the Java SE, "Java" and "All" NetBeans Bundles. You can download standalone JDK or download the latest JDK6 Update 7 with NetBeans IDE Java SE bundle.
BTW, I think that Erno told me (or might be here on the list or in some issue), that some part of, mmm.... Glassfish deployment?, really do not remember... needs JDK, not JRE only.

Yes, that is exactly what I am trying to find out. What can you NOT do with NetBeans Ruby if you do not have the JDK.
Can you use Java in your JRuby source?
Can you deploy to GlassFish?
What have I not thought of, that would not work without a JDK?
What happens when you try to do these things without a JDK? What does the IDE do? Do you get error messages, NPEs, what?

Interesting. The Ruby Only NetBeans comes with the GlassFish app server,
and new projects deploy to GlassFish by default. Does this work
seamlessly on systems without a JDK?

I think GlassFish requires a JDK, or at least some kind of a patched JRE
for compiling JSPs when running Java web apps. There may be also other
things in the app server that require a JDK. If nobody else here knows
more, we'll need to take this to some GF mailing list.

I like to actually experience what it is that I write, but I can't in
this situation. So, I am still looking for some who can experience this
for me and can tell me what exactly happens when you create your first
project, which I assume defaults to the GlassFish server, and you accept
the defaults. What happens when you hit the Run button?
Also, what happens when you start including Java packages or using Java
classes in your source? Do you get errors in the editor? What happens
when you try to run the app?

I don't know if anyone has ever tried this.
There are some parts of GlassFish that require a JDK. Most parts do
not. It's doubtful that any of the parts that require a JDK are
commonly in use by Rails applications, but it's possible.
I coded the plugin (hopefully correctly) to handle this in that if the
user is running the IDE with a JRE, then we will start GlassFish with a
JRE. It ought to just work.
That said, I would not recommend that people, even Rails developers, use
the JRE. I would recommend they use a JDK. There are lots of extra
development tools in a JDK that are not present in the JRE and you never
know when they might prove useful. For example, none of jar, jstack,
jps, jmap or jhat are included in the JRE.
I wonder if profiling or JVM level debugging work on a JRE? I don't know.

You mean using Java classes from JRuby? There should be no errors in the
editor, and the app should run fine. Developing a Java project does
require a JDK though, and AFAIK the modules providing Java support (e.g.
Java projects, Java editing etc.) can't be enabled when running NB on a
JRE. But we don't use these modules for providing any editor features
for Java classes in JRuby code.

I created http://wiki.netbeans.org/FaqRunningRubyIdeOnJre, everyone
please add there any features you're aware of that don't work with a JRE
only.
