Subject: load balancer setup?

To clustered/load balanced Orion users,

I was wondering if anyone has configured the Orion loadbalancer with non-SSL
and SSL websites within the same server? We've got this configuration on our
ecom apps and I'm not sure how to proceed with load balancer configs for
this. I've looked in the archives for these areas but could find no details.

1. Since my website has SSL, I'm not sure how to configure this for use with
the load balancer? Do I need to register the SSL webserver ports in the load
balancer.xml too? Some clarification here would help.

2. My applications have a configuration file that tells my web apps/system
things like: what is the base HREF for both non-SSL and SSL pages. Should I
be reconfiguring these values to point back to the loadbalancer host/port or
should these stay pointed to the actual instance of the application itself?

Thanks in advance,
Mike

more question for xml,xsl in orion

[Terence Kwan]

I have a XML with data and XSL with the layout information AND JSP Java code in it. 
How can I tell orion to:
1. Put XML and XSL together and output JSP.
2. Then compile the JSP output to html.

I can get XML and XSL to merge together but the JSP compiler will not compiler the JSP 
output. For example, here is the code.

Thanks

I had the same problem with ldap.jar & providerutil.jar (providers for
JNDI).

The problem is that due to the way Orion does its classloading mail.jar
classes
are loaded by an Orion classloader (via the manifest in the orion.jar) at a
*lower*
level than the classloader that handles orion/lib.  The ways you can fix
this (which
are both kind of hacks IMO) are to put pop3.jar in your jre/lib/ext
directory, or run
orion as "java -classpath orion.jar:pop3.jar;etc
com.evermind.server.ApplicationServer"

To make this a little simpler I have written a shell script to include all
jars in
my own "lib" dir, all orion jars, etc into a CLASSPATH var, and then run
Orion
as above - so, you can start/stop orion w/  "orion start", "orion stop",
"orion run",
etc.   If there is any interest I could send this script out...

I think the problem is really with Orion including some of the J2EE jars as
standard
in the orion.jar manifest.  It's a nice idea, but based on the above problem
it would
be easier just NOT to include them.

So, to the Orion developers out there, please:

1) don't bother to include mail.jar/jndi.jar/etc (or put them in orion/lib
instead of the
orion.jar manifest)
or
2) fix Orion classloading to work with the provider mechanisms of JavaMail
and JNDI
because
3) get Sun to change the provider mechanism to use different
classlaoders/etc is
not very likely...

Thanks,
Jake

SSL and non SSL within the same instance of the web application

[Terence Kwan]

Hello, we can setup 
SSL on the application without problem. However, can we setup SSL enable part of 
the web application? For example, I just want to setup SSL enable on the member 
area of the web site but not the whole web application. Or do we need to setup 2 
applications - one for SSL enable and one for non SSL 
enable.

Multiple developers with Orion and mailing list about web architecture

[Terence Kwan]

We are also using separate instance of orion servers for different developers on the 
same machine. However, people need to restart the server every time they upload the 
classes to the testing machine and they always kill the wrong instance of orion 
server. They are using "ps-Af|grep orion" and kill all the orion process. 

Is there any better way to kill the orion server? If you have different instance of 
orion servers on the same machine?


Also, is there any mailing list talking about web architecture? Like, 
1. is 2 P500 CPU is better than 1 P733 CPU
2. Should I use NT to host orion or linux to host orion? It is because NT has a faster 
VM (about 20-30% faster than linux VM??)
3. What is the deployment layout? Should I use RedHat LVS (Load balancing service) or 
should I use the orion load balancing service?
4. should I put the mysql database on the same machine as the orion server or should I 
put it in different machine?

RE: admin.jar only 441 bytes

The reason why I asked is because, when I did the following:

I just did a "java

In my servlet program, I call:
response.sendRedirect("http://www.yahoo.com")
It works in html. However, it does not work in WAP. 

I believe that the problem is that sendRedirect creates a redirect "HTML" file (html 
file with the reference tag in it) and send it to client instead of directly redirect 
to the URL. Since the WAP cellphone cannot under html file. It cannot do redirect.

Anyway to fix it? (I tried to use getRequestDispatcher's forward, but it does not work

where to put pop3.jar

[Terence Kwan]

I am trying to use java mail API and pop3.jar provider. Where should I put the 
pop3.jar file? I try to put it in: orion directory and orion/lib directory. However, 
none of them work. It keeps saying:
error:javax.mail.NoSuchProviderException: No provider for pop3

I think the problem is that the Java Beam Activation Framework cannot find the 
pop3.jar file.

Where should I put the pop3.jar in order for the orion server to find it?

Thanks
