xml-qstat 'pure java' documentation and installation notes
This is a temporary wiki page for alpha and beta testers of the new xml-qstat code from http://xml-qstat.org
We now have a pure-Java version and need to make changes to our installation directions, documentation and packaging methods to reflect the new, improved (and far simpler!) codebase.
I'm going to document the rough steps involved in getting the "new" xml-qstat to work, hopefully others can expand and point out problems and inaccuracies here. This wiki page will be used to create the final installation instructions that will ship with the package.
- Familiarity with the "old" directions at http://xml-qstat.org/install.html so you can see what is different
- You need your JAVA_HOME environment variable set in order for Cocoon to start
- The Grid Engine "settings.sh|csh" file must have been sourced, SGE binaries must be in your path. Cocoon will inherit your path and currently the sitemap.xml file will call 'qstat' without a full path defined. You must be able to successfully run the 'qstat -f' command yourself from the command line if there is going to be any hope that Cocoon will be able to do so!
Tested and found to work on the following platforms:
- Pre-release seed of Apple OS X "Leopard" Server with Java 1.5.0_13, Cocoon 2.1.10 and SGE 6.1u2
- Centos 5 Linux on x86 with Java 1.5.0_13, Cocoon 2.1.10 and SGE 6.1u2
- Centos 5 Linux on x86 with Java 1.5.0_13, Cocoon 2.1.10 and SGE 6.0u11
- Centos 5 Linux on x86 with Java 1.5.0_13, Cocoon 2.1.10 and SGE 6.0u10
Step by step
Step 1 - Download the latest xml-qstat code:
svn checkout svn://xml-qstat.org/xml-qstat/trunk
Step 2 - Rename the 'trunk' directory to something more sensible
zareh:tmp dag$ mv trunk xmlqstat zareh:tmp dag$ ls -l xmlqstat/ total 24 -rw-r--r-- 1 dag wheel 569 Oct 23 17:15 Changelog -rw-r--r-- 1 dag wheel 3295 Oct 23 17:15 build.xml drwxr-xr-x 4 dag wheel 136 Oct 23 17:15 java -rw-r--r-- 1 dag wheel 82 Oct 23 17:15 manifest.mf drwxr-xr-x 3 dag wheel 238 Oct 23 17:15 nbproject drwxr-xr-x 4 dag wheel 306 Oct 23 17:15 scripts drwxr-xr-x 8 dag wheel 306 Oct 23 17:15 xmlqstat
Step 3 - Download the latest Cocoon application server, install it into the xmlqstat folder (ideally)
cd xmlqstat/ wget http://www.gtlib.gatech.edu/pub/apache/cocoon/cocoon-2.1.10-src.tar.gz gzcat cocoon-2.1.10-src.tar.gz | tar xvf - zareh:xmlqstat dag$ ls -l total 24 -rw-r--r-- 1 dag wheel 569 Oct 23 17:15 Changelog -rw-r--r-- 1 dag wheel 3295 Oct 23 17:15 build.xml drwxr-xr-x 7 dag admin 952 Oct 23 16:12 cocoon-2.1.10 drwxr-xr-x 4 dag wheel 136 Oct 23 17:15 java -rw-r--r-- 1 dag wheel 82 Oct 23 17:15 manifest.mf drwxr-xr-x 3 dag wheel 238 Oct 23 17:15 nbproject drwxr-xr-x 4 dag wheel 306 Oct 23 17:15 scripts drwxr-xr-x 8 dag wheel 306 Oct 23 17:15 xmlqstat
Step 4 - Build the Cocoon web application server
cd cocoon-2.1.10 ./build.sh
Step 5 - Create the Cocoon mount-table.xml file The file should be located at cocoon-2.1.10/mount-table.xml and assuming that cocoon is in the same directory as the xmlqstat files then the mount-table.xml file would have these contents:
<mount-table> <!-- Map the browser URI "/xmlqstat" to our webapp folder --> <mount uri-prefix="xmlqstat/" src="../../../xmlqstat/"/> </mount-table>
Step 5 - Obtain the xml-qstat.jar file The checked out files from the SVN trunk/ contain the raw source code for the jar file along with the necessary Netbeans project files needed to successfully build a local copy of the jar yourself. It is unlikely that we would make end-users do this so we should be testing with a pre-built jar file to see how it works out. Note: See bottom of this page for instructions on how to build the jar locally ...
Step 6 - Install the xml-qstat.jar file into the Cocoon web application server Note that the "build" directory will not exist until you have successfully built the app server (Step 4)
cp xml-qstat.jar ./cocoon-2.1.10/build/webapp/WEB-INF/lib/
Step 7 - Start Cocoon
zareh:cocoon-2.1.10 dag$ ./cocoon.sh ./cocoon.sh: executing default action 'servlet', use -h to see other actions ./cocoon.sh: using ./build/webapp as the webapp directory -------------------- Loading -------------------- Processing repository: ./tools/jetty/lib Adding jar: ./tools/jetty/lib/jetty-4.2.23.jar Adding jar: ./tools/jetty/lib/servlet-2.3.jar Processing repository: ./lib/endorsed Adding jar: ./lib/endorsed/jakarta-bcel-20040329.jar Adding jar: ./lib/endorsed/jakarta-regexp-1.4.jar Adding jar: ./lib/endorsed/xalan-2.7.0.jar Adding jar: ./lib/endorsed/xercesImpl-2.9.0.jar Adding jar: ./lib/endorsed/xml-apis-1.3.04.jar -------------------- Executing ----------------- Main Class: org.mortbay.jetty.Server 16:14:28.042 EVENT Checking Resource aliases 16:14:28.390 EVENT Starting Jetty/4.2.23 16:14:30.139 EVENT Started WebApplicationContext[/,./build/webapp] 16:14:34.650 WARN!!

At this point the embedded webserver within Apache Cocoon will be operating on port 8888, if you want to hide this behind a real apache webserver, surf on over to the "old" installation directions located at http://xml-qstat.org/install.html and read the section on "Cocoon behind Apache Proxies".
Step 8 - Test
At this point you should be able to test by pointing your browser at the following url:
Building the xml-qstat.jar archive locally
The following shell script allowed me to build my own jar file without having to use the complex Netbeans IDE environment.
The script is now present in the SVN trunk/ so it should be already available on your system.
#!/bin/sh # Chris Dagdigian (firstname.lastname@example.org) # # This script can be used to compile and package the xml-qstat.jar file required # by Apache Cocoon for direct XML queries to the SGE Qmaster. # # Instructions: # # 1. Run this script, fix as needed until it runs properly to completion # # 2. Copy (or symlink) the resulting xml-qstat.jar file to you ... \n
The Art of Motivating Employees
Could a simple five-minute interaction with another person dramatically increase your weekly productivity?In some employment environments, the answer is yes, according to Wharton management professor Adam Grant. Grant has devoted significant chunks of his professional career to examining what motivates workers in settings that range from call centers and mail-order pharmacies to swimming pool lifeguard squads.
The Limitations of Positive Thinking
Positive thinking is so firmly enshrined in our culture that knocking it is a little like attacking motherhood or apple pie. Many persons swear by positive thinking and quite a few have been helped by it. Nevertheless, it is not a very effective tool and can be downright harmful in some cases. There are much better ways to get the benefits that positive thinking allegedly provides.
Life Through A Camera Lens"I couldnt believe how beautiful the ocean was, he commented. Ive never seen an ocean before, and then to get to see palm trees in person, and to even touch them. It was just amazing. He began thumbing through a series of photographs on his phone, each displaying an image of a palm tree."
Solar Device Brings Natural Light to Workers
Fluorescent lights are often seen as the brunt of an artificial working environment, but office workers around the world could soon have sunnier dispositions.
Awakening Our Collaborative Spirit
The physicist, David Bohm, while researching the lives of Einstein, Heisenberg, Pauli and Bohr, made a remarkable observation. Bohm noticed that their incredible breakthroughs took place through simple, open and honest conversation. He observed, for instance, that Einstein and his colleagues spent years freely meeting and conversing with each other.GoodvilleNews.com - good, positive news, inspirational stories, articles]
