Hi Pramod,

First of all go to Resource->WEB-INF-Web.xml folder of your DC.

In web.xml create env-entry. To create env-entry use following tag in the source code of the xml.

<env-entry>
            <description><DECRIPTION></description>
            <env-entry-name><ENV_NAME></env-entry-name>
            <env-entry-type><ENV_TYPE></env-entry-type>
            <env-entry-value><${<SUBTITUTION_VARIABLE_NAME>}></env-entry-value>
      </env-entry>

ENV-TYPE should same as type of substitution variable. Ex: java.lang.String

Now you can get value of Subtitution Variable using following code in your java code.

String VARIABLE_NAME= "java:comp/env/ENV_NAME";
InitialContext ctx = new InitialContext();
String SUBTITUTION_VARIABLE_VALUE= (String) ctx.lookup(VARIABLE_NAME);

I hope it helps.

Regards,

Rohit
