RE: global.asa -> Web.xml
Hi Ben,
I'm really new to Tomcat/Jsp. Would you be able to send me a sample
web.xml as what should I include if i want to use it from my Jsp. That would
be a great help..
Thanks in advance,
Regards,
Divya

Re: global.asa -> Web.xml
hi
why do not u try this statment inyour jsp?
getServletContext().getInitParameter("");
this statement will just retrieve the value of the parameter name u set in
the web.xml.
good luck

No problem.

Re: global.asa -> Web.xml
Ah, thanks Ben. Yes, I tried what I wrote prior and also tried
application.getAttribute ... but didn't realize there was a getInitParameter() method.
That did the trick.
Thanks.

It will, if you setup your JNDI resources correctly.

I'm saying that's one thing you can do. You can use context-param in
web.xml instead. That's an easier and more direct option. JNDI is
overkill for simple strings usually.

RE: global.asa -> Web.xml
Oops, you're right that line would not have compiled...I meant I use this:
DataSource ds = (DataSource) new
InitialContext().lookup(application.getInitParameter("db.jndi.dsn"));
...to get a datasource values and assumed the similar line would work for retrieving a
String:
String str = (String) new
InitialContext().lookup(application.getInitParameter("myString"));
...but no dice.
God, why does it have to be so difficult to do something so simple. I love Java for a
lot of reasons, but this kinda stuff makes me really curse it at times. Ok, so you're
saying go and read JNDI documentation and hopefully once I understand JNDI inside and
out I can finally set a freaking application constant paramter?

You're missing a lot. You should read the Servlet Specification,
specially the section on context parameters (context-param elements in
web.xml), which is what you will probably use for simple strings.
You should read the JNDI documentation for what a context (including
InitialContext) is. It doesn't have a getAttribute method, so I
seriously doubt this line of code even compiles, much less works for
datasources or any other type of JNDI resource. You could use a JNDI
context for simple strings, but that's usually overkill.

You're missing a lot. You should read the Servlet Specification,

You should read the JNDI documentation for what a context (including
InitialContext) is. It doesn't have a getAttribute method, so I
seriously doubt this line of code even compiles, much less works for
datasources or any other type of JNDI resource. You could use a JNDI
