The error message is quite clear:
Mandatory TLD element jsp-version missing or empty in TLD /WEB-INF/TldFile.tld


Your tld is missing the required element.

Thanks a million. . I dont know what those lines mean/do. I never used them in my web.xml and it worked (bear had warned me about this). But it hit me this time.

Is it necessary to know the meaning of those lines ? or just put it there when you work in a real-project ?

Basic XML: they identify the schema against which the XML will be validated.

I didnt know about "xml schema" until you told me. Now, I read that "An XML Schema describes the structure of an XML document". What does this mean ?
And about validation - what is it validated against ? And where is that "thing" against which xml is validated ?

That is a more appropriate question for the XML forum as it really has nothing to do with JSP.
