2 - tomcat-native-1.1.16 has not be (yet) release by the TC community.
3 - It is because it has only been tested on Solaris and at the time of the testing a lot of PHP extensions weren't compatible with the JVM in other platform.
4 - JBoss Web should better performance and also you an easy migration to AS. -
2. Re: JBoss Web 2.1.1.GA Questions
cvasilak Nov 19, 2008 3:33 AM (in response to cvasilak)Thanks for your reply.
I am facing with a kind of a weird problem. I have successfully installed and configured the APR Runtime using the Linux prebuild binaries from the jboss download site.
What I have done is to modify the setclasspath.sh file in $TOMCAT_HOME/bin and add the following: (this approach is suggested in the tomcat native web site)
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/java.libs/native
export LD_LIBRARY_PATH
where /opt/java.libs/native is the folder that I have stored the native libraries.
When I start jboss web in the log file(catalina.out) I get this
---------
Nov 19, 2008 10:09:12 AM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded Apache Tomcat Native library 1.1.16.
Nov 19, 2008 10:09:12 AM org.apache.catalina.core.AprLifecycleListener init
INFO: APR capabilities: IPv6 [true], sendfile [true], random [true].
Nov 19, 2008 10:09:34 AM org.apache.coyote.http11.Http11AprProtocol init
INFO: Initializing Coyote HTTP/1.1 on http-8080
Nov 19, 2008 10:09:34 AM org.apache.coyote.ajp.AjpAprProtocol init
INFO: Initializing Coyote AJP/1.3 on ajp-8009
.....
INFO: Server startup in 725 ms
------
That is it starts successfully and I can point to http://localhost:8080
The problem is that sometimes(not always) when I start the server it freezes when it displays the following in catalina.out
INFO: APR capabilities: IPv6 [true], sendfile [true], random [true].
Then You have to wait 2 or 3 minutes before the server finishes bootstrapping. Its weird because it doesn't happen all the time, but completely randomly. During that time you can't connect to http://localhost:8080
If someone willing to give some light on this?
I am using Ubuntu 8.10 and java version "1.6.0_10" (latest)

jfclere Nov 19, 2008 5:23 AM (in response to cvasilak)That happens when entropy have to be collect for SSL.
Use SSLRandomSeed=/dev/urandom in the AprLifecycleListener entry. -
4. Re: JBoss Web 2.1.1.GA Questions
cvasilak Dec 2, 2008 5:38 AM (in response to cvasilak)Hi there,
I have successfully installed and run JBoss Web 2.1.1 GA on an Ubuntu Machine 8.10 under jdk1.6_10 and works perfectly.
I have installed SSL(https) using the native OpenSSL libraries(APR downloaded from the jboss web site)
and used jsvc to start the service e.g. sudo /etc/init.d/jbossweb.sh start.
The shell script (which is an adoption from the Tomcat.sh found in the jsvc distribution) uses the jsvc binary compiled by me as found in the jboss-web/bin folder. I used the jsvc approach because in the production environment I would like to start jboss web at port 80 and 443(SSL)(only root can do this) and further have jboss run as a separate user(security policy).
The problem is that although in my configuration under Ubuntu works perfectly when I deploy it on CentOS it fails miserably. The problem is that during startup jboss-web can't find the native libraries(APR). The exact error from catalina.out
...
INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /opt/nms/jboss-web/native-libs
...
It's kind of weird, because in this path the libraries are installed.
-------------
[myproductionmachine]$ ls /opt/nms/jboss-web/native-libs/
engines libcrypto.so.0 libtcnative-1.so
libapr-1.so libcrypto.so.0.9.8 libtcnative-1.so.0
libapr-1.so.0 libexpat.so libtcnative-1.so.0.1.16
libapr-1.so.0.2.8 libexpat.so.0 libz.so
libaprutil-1.so libexpat.so.0.1.0 libz.so.1
libaprutil-1.so.0 libssl.so libz.so.1.2.3
libaprutil-1.so.0.2.8 libssl.so.0
libcrypto.so libssl.so.0.9.8
----------
The problem happens if I do
sudo /etc/init.d/jbossweb.sh start
IF I run the script it as root the problem goes away. It can find the libraries and starts OK.
The administrators gave me permission to run the script as sudo
I have double check the configurations, the paths etc but I can't find any problem. I suspect there is sth with sudo behaviour being different on CentOS and Ubuntu.
Any ideas why this happens?
The CentOS version is CentOS release 5.2 (Final)
The Ubuntu version is 8.10

5. Re: JBoss Web 2.1.1.GA Questions
peterj Dec 2, 2008 11:39 AM (in response to cvasilak)A few thoughts.
APR is not required for JBoss Web to run (note that the log entry is of type INFO). You should still be able to access the web apps on Centos.
If you can run as root but not otherwise, there is some permission issue. It might not be with the shared objects in native-libs, but could be with another shared object one of them relies on. I know there is a Linux utility you can use to test this (the utility attempts to load all shared objects reference and provides information about which shared objects it had problems with), but cannot recall what it is. -

cvasilak Dec 2, 2008 4:34 PM (in response to cvasilak)Hi Peter,
thank you for your reply
I agree too jboss-web can still run but only in the default configuration that comes with.
If you have configured APR for SSL(and others) as I do then it fails immediately upon startup and exits.
The connection as defined in conf/servel.xml
<!-- Define a APR SSL Coyote HTTP/1.1 Connector on port 443 -->
<Connector protocol="org.apache.coyote.http11.Http11AprProtocol"
....
So internally if he can't find the native.libs then it fails.
I will have a look if I can find the utility you describe, I suspect myself too there is some permission error somewhere.
I will keep you informed.

8. Re: JBoss Web 2.1.1.GA Questions
cvasilak Dec 3, 2008 5:24 AM (in response to cvasilak)For the record,
our wizard admin(!) found the solution. He added an entry to the system wide /etc/ld.so.conf.d/jboss.conf pointing to the native.libs and now sudo works as expected. (Just keep in mind that this was needed on CentOS on Ubuntu didn't have to do this). I will have an in-depth look on this.
