Enabling Java Web Start on Linux Firefox

To Enable Java Web Start on Linux Firefox:
1. Remove the IcedTea java plugin (libjavaplugin.so or javaplugin.so) link in /usr/lib64/browser-plugins. (or lib for 32 bit systems)
2. Create a link to the sun java plugin in the /usr/lib64/browser-plugins directory:

ln -s /usr/local/java/jdk/jre/lib/amd64/libnpjp2.so libnpjp2.so

(Use your java path)
That's it!
To make sure your plugin in installed type:

about:plugins

in the firefox address window.
To test the plug-in using a jnlp webstart applet, Click the 'Biorhythm applet' icon on this page:

Voila!
If webstart stops working, it is probably due to an update adding back the icedtea link. Just delete the link and webstart will work again.

Creating jaxb files from the opentravel schema

Probably the easiest way to deal with complicated xml documents is to use the jaxb tool from java. jaxb converts a schema definition from .xsd format to java classes. If you are trying to use jaxb on the opentravel.org schema there are a few gotchas:

• First, since the schema is so large, there are a few places where there are duplicate element names.
• Second, since the schema was not developed with jaxb in mind, there are a few element names (such as 'class') that are not legal in java.

Luckily, I wrote a utility that makes it a lot easier to use jaxb, called ota-schema-tools. This is part of the open source ota-tools project. You can download these tools at the sourceforge project page. After you have downloaded the tools, unzip them into a directory.

After a few quick steps, the schema tool is ready to go:
1. Download the schema(s) that you want to use from opentravel.org and drop it in the ota-schema-zip-files directory:

2. Edit the ota.xsd file in the ota-schema-tools/config/2008A directory to include only the schema you will need (or leave it alone to compile all the schema). For example, here I only want to use the OTA_Ping messages:

3. Run the schema tool:
If jaxb is not in your classpath, you will need to tell ant where it is with the -Djaxb.home=/location-of-jaxb-home flag. Also, if you are compiling a lot of schemas, you will have to set the ANT_OPTS=javac-options property. Here is what I type:

ota-schema-tools> export ANT_OPTS=-Xmx512m ota-schema-tools> ant -Djaxb.home=/usr/local/java/web/glassfish/ dist

When I run this command I get the error: OTA_TourInformation.xsd and OTA_RailAvailRS.xsd is not a part of this compilation.
No problem. The jaxb configuration file is set up to fix problems in the entire schema. Just remove these lines from the ota-schema-tools/config/2008A/jaxb/binding.xjb file:

I deleted these highlighted lines. Now run this line again from your command prompt:
ant -Djaxb.home=/usr/local/java/web/glassfish/ dist
Voila! Your schema are compiled and neatly packaged in a opentravel2008a.jar file.

Now that wasn't that hard, was it!

awstats web site statistics for glassfish

awstats is a open source web server log analyzer. Glassfish is an open source java-based web-server. Click here to check out the statistics on my two glassfish domain servers: domain1 domain2. Of course you will restrict access when you deploy this.

To get the awstats package to work with glassfish:

1. Download and untar awstats (to /usr/local/awstats)
2. Follow the instructions for installing awstats and run the configuration utility.
   Remember to create the /etc/awstats/ and /var/lib/awstats/ directories and set write permission.
   Edit the config file (/etc/awstats/yourconfigfilename) and change the LogFile property to:
   LogFile="sed -e 's/"\([0-9\.]*\)"/\1 - -/g' -e 's/"\([^"]*-0800\)"/[\1]/g' /usr/local/java/web/glassfish/domains/domain1/logs/access/server_access_log.%YYYY-0-%MM-0-%DD-0.txt |"
   where "/usr/local/java/web/glassfish" is the location of your glassfish server. Also remember to change the time zone offset (mine is -0800) to your timezome offset.
   Change the DirIcons property to:
   DirIcons="icon"
   You will probably want to change your SiteDomain and HostAliases properties to match your domain name.
   I got this info from Glen Smith's blog, Thanks!
3. Open your glassfish admin page (http://www.yourserver.com:4848), go to configuration -> http service and click the Access Logging enabled box.
   Click on the Access Log Tab and enter:
   %client.name% %datetime% %request% %status% %response.length% %header.referer% %header.user-agent%
   in the Format text box.
   This makes your log format similar to the apache log format
4. Go you your awstats/wwwroot directory and create a sub-directory WEB-INF
   Create a web.xml file in this directory that contains:
   
   <?xml version="1.0" encoding="UTF-8"?>
   <web-app id="WebApp_ID" version="2.4"
   xmlns="http://java.sun.com/xml/ns/j2ee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
   <servlet>
   <servlet-name>cgi</servlet-name>
   <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>
   <init-param>
   <param-name>debug</param-name>
   <param-value>0</param-value>
   </init-param>
   <init-param>
   <param-name>cgiPathPrefix</param-name>
   <param-value>cgi-bin</param-value>
   </init-param>
   <load-on-startup>5</load-on-startup>
   </servlet>
   <servlet-mapping>
   <servlet-name>cgi</servlet-name>
   <url-pattern>/awstats.pl</url-pattern>
   </servlet-mapping>
   </web-app>
   Afterwards, cd to the wwwroot/cgi-bin directory type chmod a-w *.pl just to be careful.
5. Now, install this as a web server in the glassfish admin screen (http://www.yourserver.com:4848)
   Applications -> Web Applications -> Deploy
   And deploy the web server directory: /usr/local/awstats/wwwroot. Make sure your context root is awstats.
   
   
   
6. Try to invoke the servlet as it's described in the awstats documentation:
   http://www.yourdomain.com/awstats/awstats.pl?config=yourconfigfilename
   You should see the awstat config data. Cool!
