How to load APR Connector (Native) in JBoss 7

问题:

I want to use Atmosphere XMPP but i need to load native connector APR. I am not very familiar as of yet with JBoss 7 so i was wondering if anyone knows how to do this? WIndows x64 or Linux x64 environment. Doesn't matter. Thanks

Assuming Linux x64 here. I am using Ubuntu 11.04 x64.

1. Download JBoss7 distribution and unzip it to a suitable directory ( from here I am assuming that you have it in your '/home/myname/tools/jboss701/' folder.

2. Start it using /jboss701/bin/standalone.sh and verify that it started properly ( check localhost:8080 url). Close the jboss for now.

3. Download the native libraries from here http://www.jboss.org/jbossweb/downloads/jboss-native-2-0-9.html . I have downloaded this one jboss-native-2.0.9-linux2-x64-ssl.tar.gz

4. Unpack it to the '/home/myname/tools/jboss701/' folder. You should see the contents of the archive in '/home/myname/tools/jboss701/bin' folder. Also, verify that you have 'native' folder under the '/home/myname/tools/jboss701/bin'

5. IMPORTANT: unfortunately, it doesn't work out of the box. You must make the following change: add the

JAVA_OPTS="$JAVA_OPTS -Djava.library.path=/home/myname/tools/jboss701/bin/native:$PATH"

string to your 'standalone.conf' file.

Start JBoss with the 'standalone.sh' script. Verify that you have the following line in the console during the JBoss startup: 'org.apache.coyote.http11.Http11AprProtocol'. If you see 'org.apache.coyote.http11.Http11AprProtocol' instead of 'org.apache.coyote.http11.Http11Protocol' then everything is working as expected.

Thanks man, i got it working. I do see these lines now in my startup script. `15:13:09,687 INFO [org.apache.catalina.core.AprLifecycleListener] (MSC service thread 1-7) An older version 1.1.20 of the Apache Tomcat Native li brary is installed, while Tomcat recommends version greater then 1.1.21

15:13:11,110 INFO [org.apache.coyote.http11.Http11AprProtocol] (MSC service thread 1-3) Starting Coyote HTTP/1.1 on http--127.0.0.1-8080` Atmosphere unforunately, is still throwing the same error.
