[gentoo-java] Application server for JEE

[Daniel Piccoli]

Hi,

what is the recommended application server to use under Gentoo? Is JBoss
better than glassfish? I need support for the new JEE stuff.

Thanks

Jboss -> J2EE 1.4
Glassfish -> J2EE 1.5

So im guessing glassfish

Thanks Alistair,

the reason I ask is because I have been using Glassfish with Netbeans
5.5 beta 2 (both downloaded, not emerged) and the development platform
does not seem stabe. eg. I try to do things like start the app server,
the progress bar shows that the cpu is doing something but top reveals
that it is not.

I would like to think that Netbeans and Glassfish are as stable under
Gentoo as they are under Windows as they both use Java which is
supposedly platform independent. I would really like to use Gentoo to do
my development work for my job. However, if usability is not good under
linux, I will have to switch.

Hi Daniel,

For me this raises a possibility we've been concerned with regarding  
the DLJ release that y'all are using on Gentoo.  Namely at Sun we are  
not testing on Gentoo, we test on Redhat or Suse etc (there's a list  
somewhere).  Because we, at Sun, don't test on Gentoo some on the  
team were (and are) worried that some niggling incompatibility at the  
Linux level might cause a behavior difference in Java.

Obviously Java creates platform independence by abstracting the  
operating system, making for a dependency between Java and the OS.

Not that I know that's the case here.  I just wanted to throw this  
out as a possibility.

e.g. have you made sure you're using the same versions of the JDK, of  
Netbeans, and of Glassfish, and that you're seeing different behavior  
and the only difference is that it's Gentoo in one case and Windows  
in another?  And what happens if you run this combination on one of  
the Linux's that are on Sun's supported platform list?

Thanks David,

I don't have access to all of the platforms to be able to compare, but I
have just downloaded glassfish V1 UR1 Build 14 and Netbeans 5.5 RC1.
Hopefully these will work ok.

Regards,

Dan

This statement arouses my curiosity.  It seems that because you can
"tweak the Linux level" (meaning: tweak the underlying OS libraries
and kernel), one would want to test java (compiler and JVM) on this
platform.

As part of a test suite, you could try and hinder the performance of a
JVM by modifying compiler flags and kernel parameters.  On the same
token, you could try and maximize the performance (for various goals)
of a JVM by different modifications.

Then, with these results, a sort of performance matrix could be
created showing the particular kernel parameters against various
performance goals (such as flops, or graphics, or EE beans, or servlet
load, etc).

I am not suggesting Sun should do this work, but I am suggesting that
Gentoo seems to be an ideal platform (on any/all supported hardware)
to "tune" java to maximum performance, depending on one's goals.

If you run GlassFish using ordinary user account (not administrative one),
this is exactly what happens, no matter if it's Windows or Linux. You have
to be the owner of GlassFish directories and files to run it successfully.
Group ownership is not enough in this case (I too wonder why).

Just a quick:

chown -R piccoli:users /opt/glassfish-9.0-b48

(or similar) and your'e golden.

I have jdk-1.6.0-b100, NetBeans 5.5 RC1, GlassFish b48 and Enterprise
Pack 5.5 Beta installed [manually] and I haven't noticed any big problems
(apart from the aforementioned ownership requirement).

Let us know if this helps you too.

Hi All,

Wiktor's recommendation seems to be working so far (thanks). 

The earlier problem with a unit test hanging has now proven to be a lock
with the Oracle database while persisting something. I have reinstalled
Oracle and everything seems ok now.
