Before I started my attempt to get JBoss -> Tomcat -> Warp -> Apache working, I had Tomcat -> Warp -> Apache working under Solaris and I got the same errors in the logs.
Here's what I know: (I'm using Solaris 8, JDK1.3, Tomcat 4.0.1, Apache 1.3.22)
1. When Apache starts up I got the following errors...
[Mon Feb 18 14:58:54 2002] [warn] Loaded DSO libexec/mod_webapp.so uses plain Apache 1.3 API, this module might crash under EAPI! (please recompile it with -DEAPI)
2. When using the version above, I get the errors you mention in the log file and I do have general process instability. (Every 3-4 weeks Apache just crashes.)
3. Last last week, I did the suggested recompile in the error messages, there is no longer an error at startup, and I have yet to see the Premature packet header end error.... but that doesn't mean that I won't....
I hope that helps, but now I have a Tomcat WARP Connector question for you...
I have succeeded in getting WARP to correctly deploy .war files in $CATALINA_HOME/webapps But what I really want is for warp to be able to deploy the .war components of .ear files.
In other words, I have not been able to get the tomcat-test.ear file that comes with the JBoss+Tomcat bundle to work while under warp. There is another forum thread where someone mentions that they use:
WebAppDeploy jboss conn /jboss
but that just doesn't make sense... I know the context for the tomcat-test.ear file is jboss, and I've gotten that working with just the HTTP Connector, but lets suppose for a minute I have an irrational desire to get WARP working :-) Can you tell me how yours is set up if you are in fact able to reference .ear files through WARP? Thanks, hope the info above was helpful.
As for the EAPI problem, I had already fixed this one, so sadly it isn't the cause of my problem. Although I have a suspicion that I am only getting the errors when, static content is being retrieved - particularly binary data.
As for your question, I am happy to help with what I know. You may already know some of the stuff I mention below, but I will elaborate for others that are trying to get this working.
Firsty, you must deploy your .ear files in $JBOSS_HOME/deploy rather than $CATALINA_HOME/webapps.
AFAIK, $CATALINA_HOME/webapps is redundant when using JBoss.
To get the WARP connector working, you basically need to edit two conf files: your jboss.jcml and your httpd.conf ( for apache ).
Some people may prefer to put the httpd.conf changes into a separate conf file (e.g. warp.conf) and link them in to the main httpd.conf.
If you already have Tomcat+Warp+Apache working, the chances are, you have already editted your httpd.conf.
If not, you will need to add some lines like this:
# Change this to point to the path of your module
LoadModule webapp_module /usr/lib/apache/mod_webapp.so
WebAppConnection conn warp localhost:8008
# Replace your_application below with the name of your
# war file, minus the .war extension
# The forward slash at the end indicates that the
# application will be deployed from the (URLs) root path.
# You can change this to be whatever path you wish your
# application to run from.
# e.g. if you change it to /foo, then you will be
# able to access you application as:
WebAppDeploy your_application conn /
# This is useful if you wish to debug your installation
Now for you jboss.jcml. This is where the fun starts as this will *only* work in JBoss 2.4.4, although I haven't tried in on 3.0a. This took some figuring out as the JBoss docs were all wrong. :-)
Find your catalina mbean and change it as below (Sorry about the tab damage).
Now if your .ear file has deployed correctly in $JBOSS/deploy, then you should be able to access your apps from apache.
If the above doesn't work for you, then the first thing to try, is to access your application from Tomcat's port 8080. If you can't access your application from that port either, then there is probably something wrong with your ear file, rather than your WARP configuration.
Hope this of some help.
Oops, I've just noticed that I forgot the close the
attribute tag, in the jboss.jcml config I posted above.
But you spotted that, right? :-)
Has anybody managed to do this AND use virtual hosts?
I have Apache, Warp, and the JBoss2.4.4 + Tomcat 4.0.1 bundle working using the config Pete suggests, but when I try to use a virtual host, Catalina tries to find the webapp under it's webapps directory rather than using the deployed ear file from JBoss.
My additions to httpd.conf are:
WebAppConnection conn warp localhost:8008
WebAppDeploy jobsite conn /jobsite/
With this config and ike.home and pickle.home in another machine's hosts file (linux machines), I can happily browse to either virtual host from the other machine (for plain html files served by Apache).
I can also access the jobsite.ear deployed in JBoss using either http://pickle.home:8080/jobsite or http://ike.home:8080/jobsite.
But as soon as I try http://pickle.home/jobsite (or even http://ike.home/jobsite), Catalina looks for jobsite.war in it's webapps directory. The EmbeddedCatalinaServiceSX repeats an error message over and over to that effect. Here's the JBoss output from just when it deploys the ear file to when I connect via Apache:

Catalina would normally look in it's webapps directory for war files, but I guess when it's bundled with JBoss, the EmbeddedCatalinaServiceSX reconfigures it so it can find the webapp once it's been deployed from the ear file. I know the bundled Catalina doesn't use it's server.xml file as I can connect to the webapp on port 8080 even if I delete it, so there's no point changing server.xml.
The WarpConnector is a configuration parameter of EmbeddedCatalinaServiceSX, so is there another attribute I need to use to make it work with a virtual host?
At last, figured it out. Looking at the source, I found that org.jboss.web.catalina.EmbeddedCatalinaServiceSXMBean has a setBindAddress method (don't you just love open source?), so I changed my jboss.jcml to this:
and it works. I can see the webapp on http://pickle.home/jobsite, but I can't see it on http://ike.home/jobsite, which is correct.
There were a few error messages when I first connected, but I but I think they're a red herring:
[12:21:24,513 ERROR EmbeddedCatalinaServiceSX] [org.apache.catalina.connector.warp.WarpConnector] Connection from localhost.localdomain/127.0.0.1:38227 to localhost.localdomain/127.0.0.1:8008

[12:21:24,589 ERROR EmbeddedCatalinaServiceSX] [org.apache.catalina.connector.warp.WarpConfigurationHandler] Filter mappings (0)
The messages come out of the Warp connector and the EmbeddedCatalinaServiceSX is reporting them as errors even though they don't appear to be real errors if you look at the Warp source.
I hope this helps anyone else trying to use Warp, JBoss and virtual hosts. Now that I'm finished, my desk has more hair than I do :-)
I have followed the procedure as mentioned by you. Here are the configuration of my jboss.jcml.
I have addres the BindAdress attribute later. It did not work without bind address as well.
My Apache config is:
WebAppConnection warpConnection warp localhost:8008
WebAppDeploy emergingtrade warpConnection /emergingtrade/
WebAppConnection warpConnectionTest warp localhost:8008
WebAppDeploy examples warpConnectionTest /examples/
The example application is working as it is deployed in the catalina/webapps directory.
Thanks for you kind help in advance.
I figured it out. it is working now.
The bind address attribute in the jboss.jcml is required even if you are not using the virutal hosts in Apache. The name of the bind adress must match with the ServerName directive of the Apache server. I was using the ptrader name in apache and localhost in the jboss.jcml.
Thanks to all for the kind help.
I don't understand. Here is my tomcat4-service.xml part that I have added.
I added the second part with the WarpConnector. The listener started correctly.
Here is my httpd.conf :
LoadModule webapp_module modules/mod_webapp.so
WebAppConnection wco warp 127.0.0.1:8008
WebAppDeploy jive wco /jive
When I restart apache, in my jboss log, I have this:
2002-07-08 16:31:27,568 ERROR [org.jboss.web.localhost.Engine] [org.apache.catalina.connector.warp.WarpConfigurationHandler] Cannot find "../catalina/webapps/jive" for appl. "jive" host "127.0.0.1"
