JSP 2.0 validation on a Java Project (not a Dynamic Web project) [message #496693]

Hi there,

I am having a problem with validating my JSPs. I can do the following without Eclipse complaining:

<%@taglib uri='/WEB-INF/cheese.tld' prefix='cheese' %>

but when I try to use 'tagdir' which is JSP 2.0 syntax, it does not allow me to, saying that 'uri' is a required attribute and that there is no such thing as a 'tagdir' attribute. e.g.

<%@taglib tagdir="/tags/" prefix="m" %>

From about Eclipse:
Eclipse Java EE IDE for Web Developers.

Build id: 20090920-1017

This code resides in a Java Project rather than a Dynamic Web Project, but I can not found anywhere that tells the JSP validator to switch to JSP 2.0 validation.

Is the only way around this to switch to a dynamic web project or can I somehow fix Eclipse and tell it to validate correctly?

Any help would be greatly appreciated.

Alman,

Can you check what version of WTP you are running on? I expect 3.1, but if you could check that would be helpful.

I tried this scenario on the latest stable WTP 3.2 milestone and did not see the problem but I think JSP 2.0 validation should be present in 3.1 as well, hence my curiosity about your WTP version.

Thank You,

~Ian

Hey Ian, thanks for the reply. The version of WTP is as follows:

Eclipse Web Developer Tools

Version: 3.1.1.v200908120400-7R77FSpEVw2xXR0CtKvX6bG6a2qU
Build id: 20090616035105

I've tried updating it but the eclipse updater says it is up to date.

Which DTD/Schema is your WEB-INF/web.xml file referencing? In a
Java project, we attempt to infer the Servlet and JSP specification
versions based on that (or the version attribute of the web-app
element if it's present), and earlier versions of the specs didn't
have a tagdir attribute available.

Nitin, you have solved my issue! Thanks so much!

The web.xml had the following:

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

which I have now changed to:

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.5//EN" "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

and all is well! I appreciate your effort.
