glassfish

I have a struts2 (2.1.6) based webapp which has two languages - english and norwegian. The default language for the app is norwegian - the application server (glassfish 2.1) is running under the english locale.

It didn't seem to matter what value I passed in to the request_locale parameter - I always got english.

There are two language files:

• global_messages.properties (norwegian)
• global_messages_en.properties (english)

The struts constant struts.custom.i18n.resources was set to "global_messages" in struts.xml.

After running continuous integration with continuum for a long while (which works great for maven projects) I decided to take a look at Hudson. It can also do maven - but seems to have a larger range of plugins available. Of interest to me was grails.

Installation

This was extremely simple - I just grabbed the hudson.war file from the hudson site and deployed it in a running glassfish.

LDAP configuration

One of the systems that can be used for monitoring trends on a system is munin. It turns out that adding a graph to munin is reasonably simple.

There is a good guide on the munin site.

So - I need a plugin that will return the number of open files.

lsof -u glassfish | wc -l

My glassfish process kept dying with "Too many open files" in the log.

I'm not surprised that it has too many - it has quite a few large applications running - but how to increase this?

ulimit -n shows that the user has a default of 1024.

But ulimit -n 2048 gives -su: ulimit: open files: cannot modify limit: Operation not permitted

Some digging leads to /etc/security/limits.conf

Here we added:

Instead of using a self-signed certificate with glassfish (see Creating new SSL keys with keytool for glassfish) - we want to use one that is signed by a certificate authority.

Based on http://blogs.sun.com/enterprisetechtips/entry/using_ssl_with_glassfish_v2

For this entire post - the keystore.jks file is the one found in the glassfish domain config - e.g. glassfish/domains/domain1/config/keystore.jks

I needed to generate a new certificate for glassfish's admin pages.

Instead of using the normal OpenSSL self-signed certificate it was easier just to use the java keystore keytool

keytool -genkey -keyalg RSA -alias
<alias_referred_to_in_glassfish>
-keystore glassfish/domains/domain1/config/keystore.jks
-storepass changeit

Note the -keyalg RSA - keytool by default uses DSA and firefox 3.0 will not accept this even with an added security exception.

I have had jira and confluence running under tomcat 5.5.23 (behind apache over AJP13/mod_jk) for a while now. The aim is to migrate them over to glassfish (behind the same apache but with mod_proxy).

Software versions:

• Atlassian Jira 3.12.2
• Atlassian Confluence 2.8.0
• Apache Tomcat 5.5.23
• Glassfish 2.1 build 39
