JBoss-2.4.5/Tomcat-4.0.3 + Virtual Hosts

[jkramer]

Greetings,
I fear this topic may be beaten to death but I am in need of some guidance. I know JBoss 2.4.5 has support for virtual hosts as per the change log. What I need to know is which files need to be configured to allow this, as well as how to alter those files.
Despite being new to Java development and newer still to JBoss inparticular, I have been charged with the task (not one I've sought) of determining how best to move our applications from Orion to JBoss (for which virtual hosting is an absolute necessity). I've gotten an existing application to run under JBoss-2.4.4 so only the virtual hosting issue is of concern to me at this point.
Normally I would quite enjoy sorting though everything in my own time learning it and letting it soak in and all, unfortunately I am not graced with the luxury of time, so any help would be welcome help.
I should also note that as of this posting I am still downloading the JBoss-2.4.5_Tomcat-4.0.3.zip file (sourceforge is particularily slow today), so it may very well be when I view the conf files it will all be clear, but for now I'm hedging my bets :)

Thank you kindly in advance,
~Jakob Kramer

Hi,

Wow this is good news. I was using a patch from Alain Cotemeur for jboss2.4.4. So, I´m downloading now aswell and maybe I can come up with an answer (if nobody else posts).

Hope you don´t mind me using this thread for another question. Does that mean that jboss3.0 does or will eventually support virtual hosts aswell? More good news!

Well, I ended up downloading a corrupted zip-archive at 4kb/s. So next try :-).

Is someone reading this thread?

I posted this same question to the users mailing list and this is the reply I got from Scott Stark:

An example jboss.jcml EmbeddedCatalinaServiceSX mbean config with
localhost and succubus virtual hosts:


<!-- The embedded Tomcat-4.x(Catalina) service configuration -->













www.starkinternational.com
main.starkinternational.com






<!-- A HTTP Connector on port 8080 -->







A war deployed to the virtual host succubs under the root context
needs to include a WEB-INF/jboss-web.xml descriptor with:


<jboss-web>
<context-root>/</context-root>
<virtual-host>succubus</virtual-host>
</jboss-web>

I have tried this and it works so... Woohoo and Yippee and all other shouts of joy.

Thanks Scott, and I hope this helps anyone else too.

Thanks!

Doesn´t look too hard. As I haven´t managed to download jboss2.4.5 yet (it keeps stopping half-way and I end up with yet another corrupted zip file), I have been trying the same configuration with jboss3.0.

It´s not working yet, although I have the feeling that I´m getting there.

I´ll try asking my question again :-), will the above configuration also work with jboss3.0?

Me again (zzzzzz) !

I´ve managed to download the jboss2.4.5+tomcat4.0.3 bundle. I´ve also set up the virtual hosts exactly the way it has been described above.

Could someone explain to me why I´m getting the following errors when restarting apache:

===================================================================

I´ve got the feeling as if I´m talking to myself. Could someone PLEASE give me an answer to my questions.

Michael,

I don't know the answer to your question since I myself am not using apache and so cannot replicate the error, but I have asked around the office with people more familiar with apache than I, but they don't have any ideas straight away.

My question to you though is this: Were you able to configure each virtual host (each independant application) to use a different data source, if so how did you do this?

Cheers,
Jakob Kramer

Hi Jakob,

I´m not sure exactly what you mean. Do you mean deploying in several directories, i.e. one for each application?

As far as I know you can specify this in the jboss.jcml.
This is what I did:

<!-- ==================================================================== -->
<!-- Auto deployment -->
<!-- ==================================================================== -->


J2EE:service=J2eeDeployer;
JCA:service=RARDeployer

../deploy,../deploy/lib,/www/servtest/java</attribute


You´ll notice that I have added "/www/servtest/java".

Now I´m not sure wether this is the "only" or the "best" solution but it works.

bye Michael Delamere

[mdelamere]

Well actually I have "/www/servtest/java/deploy" but I think you get my point :-)

[jkramer]

I understand about the seperate directory thing. What I am curious about is whether or not I can have application a connect to database a and have application b connect to database b.

Thanks,
~Jakob Kramer

Sorry, I don´t have an answer to that question. However, I can´t imagine it.

You would be better off asking these types of questions to the tomcat-user mailing list. It´s near to impossible getting an answer in this forum!!

regards

Michael Delamere

p.s. Coming back to the virtual host question :-) :
did you ever get this error message from tomcat:

"The requested resource (/examples/) is not available."

[mdelamere]

oh oh, got it wrong again. I meant the jboss-users mailing list of course!

That´s what happens to you when you hardly sleep for almost a week because you´re trying to get all this setup!

Sorry Jakob,
I can see in the output the [Engine] picking up my new host but I'm missing something. I can deploy under the virtual host;

http://www.mycompany.com/myApp

but having trouble deploying a .ear directly to

http://www.mycompany.com

Where am I going wrong?

Cheers
Sean

[seanhowell]

Ok, scratch that, I figured it out.
I can now join in the cheers, hooray!

Thanks guys.
