WebLogic Workshop - Custom Project Template

In WebLogic Workshop 9.1 and above, we can create following directory structure create custom EAR application, which can be used under Eclipse.

Best Practices from (edocs.bea.com)

# Use the same source directory structure with your own J2EE application projects, so you can utilize the WebLogic Server build scripts to compile and deploy your applications. The following summarizes the contents of a simple source directory that follows the WebLogic split development directory structure format:

\myProject

\myProject\myEar

\myProject\myEar\META-INF\application.xml

\myProject\myEar\myEjb\com\*\MyEjbGenEjb.ejb

\myProject\myEar\myEjb\com\*\*.java

\myProject\myEar\myWebService\com\*.*.java

\myProject\myEar\myWebApp\*.jsp

\myProject\myEar\myWebApp\WEB-INF\web.xml

\myProject\myEar\myWebApp\WEB-INF\src\com\*\*.java

Spring Framework - Two Articles on Form Validation with DWR and AJAX

Spring Framework - Two Articles on Form Validation with DWR and AJAX
Submitted by Colin Sampaleanu on Thu, 2007-04-19 23:09. Technical Article
Using AJAX (via DWR) to perform client-side validation is a useful technique that allows the implementation of both client side and server side form validation, while actually using the same (server-side) validators for both task. Here are a couple of articles that describe this technique.
Generic Validator for Spring MVC and DWR by Jose Noheda, shows one approach. His validators work off annotations in the objects to be validated (this is somewhat orthogonal to the question of validating remotely).

Oracle 9i - How to add missing partitions

Assume, We need to insert missing partition as new partition with Oracle Range Partition.

Here is the simple example for that.

create table karth_test (a date,data char(10))
partition by range(a)
( partition p1 values less than (to_date('2007-01-01','YYYY-MM-DD')),
partition p2 values less than (to_date('2007-02-01','YYYY-MM-DD')),
partition p4 values less than (to_date('2007-04-01','YYYY-MM-DD'))
)

select partition_name pname, high_value from user_tab_partitions
where table_name ='KARTH_TEST' order by partition_name

alter table KARTH_TEST add partition p3 values less than (TO_DATE('2007-03-01','YYYY-MM-DD'))

-- Above statement raises ORA-14074: partition bound must collate higher than that of the last partition.

-- We can execute following statement to overcome above error

Alter table KARTH_TEST split partition p4 at (TO_DATE('2007-03-01','YYYY-MM-DD'))
into (partition p3, partition p4)

Drop table KARTH_TEST
