How to deploy web project on tomcat?

07Apr09

There are two methods to deploy an application in tomcat

1- Deploy the application in webapps directory directly under tomcat directory.

Put the .war file of project in webapp directory and restart tomcat.

2- You have a working project with correct directory structure anywhere on filesystem and you want to deploy that without moving it to webapps directory.

But I don’t wanna create a war file then putting it in webapps directory and later on whenever I make a change I’ll have to deploy it again.

Get duplicated records in a database table

05Apr09

I  had a situation, I wanted to find out all records in a single database table which occur more than once.

In one of the database tables there were some records that were repeating and I wanted to get all those records, how many times were repeating etc.

So here is the shortened version of my database table

CREATE TABLE HD_DESIG
(
DESIG_ID              NUMBER(10)              NOT NULL,
DESGIG_ORDER          NUMBER(2),
DESIG_ENAME           VARCHAR2(200 BYTE),
DESC_EN               VARCHAR2(300 BYTE),
)

First we will group all the same records and find the group count

SELECT HD_DESIG.desig_id,COUNT(*) cnt FROM HD_DESIG GROUP BY HD_DESIG.DESIG_ID;

Secondly, we will get only those records that have a count greater than one – only those records that exist more than once.

SELECT desig_id  FROM
(SELECT HD_DESIG.desig_id,COUNT(*) cnt FROM HD_DESIG GROUP BY HD_DESIG.DESIG_ID)
WHERE cnt > 1;

Now I’ll combine the above queries along with some more changes and we will get the information of all those records that are repeating.

Here is the whole query.

SELECT * FROM HD_DESIG WHERE HD_DESIG.DESIG_ID IN
(
SELECT desig_id  FROM
(SELECT HD_DESIG.desig_id,COUNT(*) cnt FROM HD_DESIG GROUP BY HD_DESIG.DESIG_ID)
WHERE cnt > 1
)

Arabic converted to question marks “????” on JSP form

31Mar09

Its been pain to solve the windows-1256 character set (Arabic) problem. Many times when my JSP form is submitted all the Arabic in fields turn to “?????” and the original Arabic text is lost.

I have one line solution for this. But I can not assure you that it will work in all scenarios. But it may prove helpful.

If you are showing Arabic on your form, then you may already be doing this

    response.setContentType("text/html;charset=windows-1256");
    response.setHeader("Content-Language" , "ar");

You can place the following line at the top of the page which could solve your problems.

    request.setCharacterEncoding("windows-1256");

Try it and if you have any questions, leave comments.
