Try



I guess that you are just trying to get familiar with JSP's. In general, having methods in JSP's turns into a maintenance nightmare. You should do all your processing in normal Java classes, and use JSP's only to display the data.

Hi,
The line
<%! propManager.getProperty("projectDesc") %>
contanins the fundamental syntax error.

THe <%! .. %> is declaration tag for JSP.That why
Try <%= .. %> it will work.

Thanx.
Vinod

Thanx and Regards,<br />Vinod

The <%= %> tags only work to print out a string that is returned by the code betweent them. This is the same as writing the code:

I believe that was the intent of the poster.

And, it doesn't have to be a string; the expression within the delimiters can return any class or primitive. In the case that a class is returned, the toString() method is called on the class to determine the value to emit.
