External Configuration With JBoss

Often we need to keep properties outside the war file / ear file.

Jboss has an interesting way of doing this. Check this out.

Find an ASCII code

Often web developers , who use javascript for validations are not able to recollect ascii codes for keys from the top of their head.

http://www.whatasciicode.com/

This site lists the keys and corresponding ascii codes in tabular form. Whenver, you get stuck , just go ahead load the site and refer it at your will. Hope this helps

Logwatcher plugin for eclipse

I found this plugin while surfing. This plugin is similar to "tail" command in Unix that helps to see the log file contents in real time if you give a -f switch.

You can get the plugin from : http://graysky.sourceforge.net/

Really useful plugin. Now I don't have to go to command line at all for watching log files.

Oracle Application Server Administration Made Easy

Opmnctl utility:
Opmnctl is a command line utility provided for starting, stopping,restarting and getting status of various ias components.

options available :

1) opmnctl start : Starts the opmn daemon without starting opmn managed instances

2) opmnctl startall : Starts both the daemon and managed server processes

3) opmnctl stopall : stops all the managed instances

4) To start a specific component
opmnctl startproc ias-component=OC4J process-type=

5) To stop a specific component
opmnctl stopproc ias-component=OC4J process-type=

6) To validate opmn.xml : opmnctl validate opmn.xml

7) To shutdown forcefully opmn managed processes and daemon :
opmnctl shutdown

All ias-components will have an entry in opmn.xml . This is located in $ORACLE_HOME/opmn/conf/opmn.xml

for a OC4J component entry will be like :

ias-component id="OC4J"
process-type id="" module-id="OC4J"
module-data
category id="start-parameters"
data id="java-options" value=""
data id="oc4j-options" value=""
category

category id="stop-parameters"
 data id="java-options" value=""
category

module-data
process-type
ias-component

All ias-component specific logs are located in $ORACLE_HOME/oasmt/opmn/logs/ directory . If any component refuses to start or shuts down abnormally, go to that directory and have a look.

Deploying J2EE Application using OC4J in 10gAS

Step 1 : Create OC4J Component
a) cd $ORACLE_HOME/oasmt/dcm/bin
b) dcmctl createComponent -ct -co

Step 2: Deploy new component
a) FTP Ear file that you have created to the server .
b) dcmctl deployApplication - file -a -co

Step 3 : Start new component
a) dcmctl start -co -d -v

To restart component :

dcmctl restart -co -d -v

To stop component :

dcmctl stop -co -d -v

To undeploy component

dcmctl undeployApplication -a -co

To remove component
dcmctl removeComponent -co

Back from Vacation

I am back from 1 week Vacation . Yesterday , When I was working on writing JDBC code, i found that returning auto generated keys is supported by JDBC 3.0 . So I went ahead and downloaded the latest ojdbc14.jar and deployed my war in tomcat. Worked without any issues. However, when i deployed the same in 10g AS it gave an abstract method error. Then , when I printed out the driver version property to my utter dismay i found that it was printing 9 and not 10 . After further investigations i found that you need to force 10g AS to use the new jdbc driver.
I went to Java Options for the oc4j instance and added the following as suggested by Oracle forums :
-Xbootclasspath/a:/0gAS home/jdbc/lib/ojdbc14.jar

Then after restarting the oc4j instance, it started working as expected. I am still left wondering though why it did not use the ojdbc14.jar that is in my web-inf/lib directory of the project. Any suggestions/comments are welcome

I have changed the look and feel of my blog, courtesy a nice template provided by Blogspot.

Learnings for Today

I was creating a map and using the key as a java.sql.Date object. I created a sql Date by the valueof builtin which accepts the yyyy-mm-dd format. When I tried to retrieve the value using the key, it failed some times. I was really surprised. It also stores the time along with the date in the object. When i try to get it , by using map.get the time is different, of course and it fails. So , i realised that it is not good to keep a date object as the key. Then i changed the code to an integer by appending yyyymmdd . Voila ! , now it works like a charm.

Rest of the day, i spent mostly on debugging jdbc code. There is a new stuff in JDBC 3.0 that allows you to return autogenerated keys. I downloaded the latest ojdbc14.jar , put it in my web-inf/lib in tomcat and it worked fine. However, when i deployed my EAR in 10g AS, for some reason it gives me an abstract method error in the preparedstatement class. I was breaking my head on that. Still to come up with a solution for that issue.

Hope to update my blog more frequently in future.

After a huge gap...

Started blogging after a huge gap. I created a presentation on "Introduction to AJAX " . Reply with your feedback on that .

Hope to blog regulary from now on
