problems with web project on wtp [message #475739]

Hello,
I use the wtp 3.0.0.v200712121937 with eclipse 3.4M5 from the Ganymede
Discovery Site and have some problems.

1. I use JSF and Trinidad and in my jsp page I get for every bean the
warning that it cannot be resolved. Code completition is missing too. And
for the action attribute I get the warning 'The action value does not match
a navigation case outcome.'. Looks like the information from
faces-context.xml is missing, can I define the location somewhere?
faces-context is in WebRoot/WEB-INF (Eclipse standard is WebContent). Same
code with Eclipse 3.3.2 and wtp 2.0.2 works fine. Also code completition for
tags, message bundles and defined vars for a table work great in 3.4
(defined vars didn't work in 3.3.2).
I added jsf 1.2 to the project facades with serverside (don't know what it
was, but no custom libs) as I did with eclipse 3.3.2. Did I miss anything?
Don't remember more from the old setup.

2. I installed Tomcat 6 runtime and added a server. When I start the server
with the application I get following error.

This listener is defined in web.xml
<listener>
<listener-class>mypackage......listener.ApplicationListener </listener-class>
</listener>
and implements ServletContextListener

Server runs also fine with Eclipse 3.3.2 and wtp 2.0.2

Thanks, Tobias

Problem 1: Support for Trinidad tags within WTP has come fairly recently.
You may wish to try a recent WTP I-Build available from
http://download.eclipse.org/webtools/downloads/ to see if your problems
are resolved.

In general when you are dealing with pre-release Eclipse software, it is
best to ensure that you are using the same pre-requisite plugins used at
the time of that build. The update sites will only be accurate for
released software.

Problem 2: Sorry, but I can't help you on this one. This question would
be better answered on the eclipse.webtools newsgroup or an Apache Tomcat
forum.

Hello,
thanks for your info.
Prolem 1 is solved in
http://download.eclipse.org/webtools/downloads/drops/R3.0/I- I20080321174820-20080321174820/
and the required packages.
Code completition for jsf action attribute and css is realy nice. It works
also for the var attribut in h:dataTable but not in tr:table.

Problem 2 is still open. So if everyone in eclipse.webtools knows the answer
;)

> mypackage......listener.ApplicationListener

Is the ApplicationListener class being deployed into Tomcat's classpath?
Where is it defined? In your project's source or in a jar? If it's in a
jar, you need to make sure that the jar is being deployed.

If it's source, the Tomcat publish/launch is sometimes bad at picking up
changes (although not normally with Java files). Try right clicking the
server in the Server view, stop it, clean, clean tomcat working directory
and then restart.

The ApplicationListener is in my source code.
Clean on the Tomcat as well as clean on the code does not work. I can find
the .class file in the eclipse tomcat working directory
..metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpweba pps ... within my
package.

Hmm, is it possible that your ApplicationListener implements, extends or
uses any classes that may not be in the classpath?

The ApplicationListener implements javax.servlet.ServletContextListener
which is found in servlet-api.jar and this is located in $CATALINA_HOME$/lib
This tomcat is configured as runtime environment and is included under
project/java build path/libraries
