Issue Running web appl from Eclipse ( Apache) [message #182673]

Hi,

I am NOT able to run a web appl from Eclipse gui.
I have followed the example from WTP tutorial;
I am able to create a new server ( Apache Tom Cat ) and start it from
Eclipse tool. I am able too to link a web project to the server.
Everything looks to work fine.
However when I try to run the appl inside the Eclipse I get an error
because the jsp page doesnt exist in webapp DIR. It looks that the web app
files were not copied to Tomcat webapp tool.
When I linked the web project to the server should not these files had
been updated in Tomcat web app dir ?

Regards,
Faria

Yes, it should updates the Tomcat webapp dir, but by default, this would
be the one under ".metadata/.plugins/org.eclipse.wst.server.core/tmp?"
under your Eclipse workspace. It this where you are looking?

Cheers,
Larry

Hi Larry,

Yes! I can find the jsp page over the default path
".metadata/.plugins/org.eclipse.wst.server.core/tmp0".
Does it mean that should the sample to be already working fine ?
Or do I need manually to publish for the righ directory ( webapps of
Tomcat install dir ) ?

Best regards,
Fred

Hi Fred,

Are you trying to access "/Servlets-Tutorial/WEB-INF/main.jsp" from your
browser? If so, this is the expected behavior. The servlet spec
forbids direct browser access to the contents of the WEB-INF and
META-INF folders. However, internal servlets and JSP pages can forward
or include JSPs under WEB-INF. Add a JSP page under the WebContent
folder that contains "<jsp:forward page="/WEB-INF/main.jsp"/>" and
displaying it in your browser will display the output from main.jsp.

Hi Larry,

Thank you very much for your help.
Right now, it is working fine!! I really had created the main.jsp file
in wrong location diferently that one that Eclipse WTP Tutorial taught.
( I am a beginner for Eclipse and J2EE. ).

Fred.

Though a mistake for your main.jsp, putting JSPs in WEB-INF (or a
subfolder) is not necessarily wrong. Often a JSP is used a "viewer" and
requires some session setup, typically by a servlet, before being
invoked on a request. Putting such a JSP in WEB-INF is a convenient way
to prevent users from accessing the JSP directly and having it
malfunction without the setup.

Cheers,
Larry
