ROOT ignored in excludedContexts

[larstobi]

System info:

JBoss: jbossas-5.1.1-16.ep5.el5   (From RHEL5 RHN-channel "jbappplatform-5-x86_64-server-5-rpm")

mod_cluster: mod_cluster-1.1.3.Final-bin.zip

mod_cluster-native: mod_cluster-native-1.1.3-1.x86_64.rpm (compiled for httpd-2.2.17-11.1.ep5.el5)

{code}JAVA_OPTS+=" -Djboss.mod_cluster.excludedContexts=ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console"{code}

Even though I add ROOT to excludedContexts as specified in the docs, the / context path still registers with Apache.

What else can I do to make JBoss not register the / context?

Check the mod-cluster.sar/META-INF/mod-cluster-jboss-beans.xml

there should something like:

<property name="excludedContexts">${jboss.modcluster.excludedContexts:ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console}</property>

So it is -Djboss.modcluster.excludedContexts .... Note you try to use the default doing nothing should have work.

[larstobi]

This line is unchanged by me and straight from the 1.1.3 tarball:

<property name="excludedContexts">${jboss.mod_cluster.excludedContexts,jboss.modcluster.excludedContexts:ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console}</property>

So, bot jboss.modcluster and jboss.mod_cluster should work, however I have also tried withhout the underscore with no luck.

However, my profile folder was a copy of the web profile, and I just tried renaming ROOT.war to jboss-ROOT.war, and excluded jboss-ROOT instead of just ROOT. Now it correctly excludes the context.

Is this a bug, or is it the correct behaviour? If it is correct behaviour, can I achieve the same without renaming ROOT.war, or is this rename required?

[jfclere]

That looks like a bug :-(

[larstobi]

Okay, then I'll file a bug report. We have a good workaround with the renaming of ROOT.war in the mean time.

I don't actually think this is a bug.  Does your server.xml specify a specific host name, e.g. <Host name="myhost">?

The values contain in excludedContexts are expected to be host-delimited.  If no host is specified, it is assumed to be "localhost".

To exclude the root context of a specific host, you would use something like this:

<property name="excludedContexts">myhost:ROOT,myhost:mycontext</property>

[pferraro]

To elaborate, when parsing the excludedContexts, mod_cluster translates "ROOT" to the "" context, not "/".  Jean-Frederic, is there a chance that the version of jbossweb in use here might be expecting "/" instead of ""?

[jfclere]

We have in main/java/org/jboss/modcluster/mcmp/impl/ResetRequestSourceImpl.java:

         if (path.equals(""))

                  path = "/";

[larstobi]

I have localhost in my server.xml, and no aliases.

FYI, I tracked down the issue to a regression caused by MODCLUSTER-220.  I've committed a fix, which will be included in 1.1.4.Final.
