in web.xml u can set all the constants u want as:
<env-entry>
<env-entry-name>nameVariavle</env-entry-name>
<env-entry-value>valueVariable</env-entry-value>
<env-entry-type>java.lang.String or whatelse</env-entry-type>
</env-entry>
and use this for getting them
public static String getEnvVar(String name)
throws NamingException
{
String var="";
try
{
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup( "java:comp/env" );
var = (String) envCtx.lookup( name );
}
catch (NamingException e) {
e.printStackTrace();
}
return var;
}
regards!!

Subject : Flexible way of defining application variables in text format?
> My webapp needs some application string variables for
> configuration. For the moment, I hard-code them as class static
> properties and compiled. But I'd like to know if there's any method to
> define such variables in a text file, something like the global.asa in
> ASP where we could simply write something like this withing the
> application_onstart subroutine:
> application("myvar") = "my value"
>
> I like them to be withing text file because if even there's a need
> to change config, I'd like to just launch a text editor, edit it and
> start again! I don't want to install Eclipse or other IDE in deployment
> server just in case we need to change some parameter and have to compile
> everything. This is very inconvenient, non professional and stupid.
> And the client would probably not appreciate this.

> OK, I know I could write a wrapper function to parse that text file
> and assign the correct values, but is there a simpler way? Is the
> answer lying in the "web.xml" file? But its syntax seems quite
> complicated that I've no idea what to begin.
