Running GlassFish V3 with Apache httpd

Posted by amyroh on June 24, 2009 at 04:36 PM | Permalink | Comments (4)

GlassFish V3 has improved the way to front GlassFish with Apache HTTP Server. Unlike the V2 way where users had to copy tomcat-ajp.jar and commons-*.jar, you can just enable mod_jk in V3 using the network-listener's attribute "jk-enabled" without copying any additional jars into its lib directory. You can also create jk-connectors under different virtual-servers (not just default virtual-server "server" in V2) using the network-listener's "jk-enabled" attribute.

Here are instructions.

(1) Install Apache HTTP Server and mod_jk

(2) Configure workers.properties and httpd.conf

For example, apache2/config/workers.properties


# Define 1 real worker using ajp13

worker.list=worker1

# Set properties for worker1 (ajp13)

worker.worker1.type=ajp13

worker.worker1.host=localhost

worker.worker1.port=8009

apache2/conf/httpd.conf


LoadModule jk_module /Users/Amy/apache2/modules/mod_jk-1.2.25-httpd-2.2.4.so

JkWorkersFile /Users/Amy/apache2/conf/worker.properties

# Where to put jk logs

JkLogFile /Users/Amy/apache2/logs/mod_jk.log

# Set the jk log level [debug/error/info]

JkLogLevel debug

# Select the log format

JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

# JkOptions indicate to send SSL KEY SIZE,

JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat set the request format

JkRequestLogFormat "%w %V %T"

# Send everything for context /examples to worker named worker1 (ajp13)

JkMount  /examples/* worker1

(3) Start Apache HTTP Server

(4) Enable mod_jk using the following command


asadmin create-http-listener --listenerport 8009 --listeneraddress 0.0.0.0 --defaultvs server my-connector


asadmin set configs.config.server-config.network-config.network-listeners.network-listener.jk-connector.jk-enabled=true

(5) If you are using the glassfish-jk.properties file and not referencing it in httpd.conf, point to it using the following command:


asadmin create-jvm-options 
-Dcom.sun.enterprise.web.connector.enableJK.propertyFile=domain-dir/config/glassfish-jk.properties

(6) Restart GlassFish

The network-listener attribute "jk-enabled" is available from V3 b53 or later.
