Unable to access servlet when deployed on Tomcat [message #82178]

Thu, 10 April 2008 03:12

Eclipse User

Hi all,

Recently I've tried to deploy our RAP application to Tomcat.
We use browser widget pointing to a servlet in our welcome view which
works fine under Jetty, but in Tomcat it throws something like unable to
find the servlet.

To register servlet we have defined it in our plugin.xml:

<extension id="com.fearnot.ui.resources"
point="org.eclipse.equinox.http.registry.resources">
<resource alias="/web" base-name="/web"/>
</extension>

<extension id="com.fearnot.ui.servlets"
point="org.eclipse.equinox.http.registry.servlets">
<servlet alias="/fes" class="com.fearnot.ui.servlets.MainServlet"
load-on-startup="true"/>
</extension>

I suspect that I can't deploy application with internal browser widget to
Tomcat as it is.

Do I have to move the declaration above to the web.xml ?

Any help would be greatly appreciated.

Best Regards,

Setya

Hi,

there should be no difference in servlet registration for deployment on
tomcat. Probably your deployment archive isn't correct. Please take a
look at the log entries and follow the thread regarding deployment of
RAP applications in this newsgroup.

Ciao

I've followed tutorial written by Elias here :
http://rapblog.innoopract.com/2007/12/rap-deployment-part-2- deploying-your.html

Actually the application is successfully deployed, I've inspected the OSGI
console and all bundles are started. But when browser widget in our
viewpart try to access url '/fes', it says 'The requested resource (/fes)
is not available'.

BTW, which log entries are you talking about ?

Hi,

are you sure that your build.properties file contains the plugin.xml?
That's a common mistake.

Besides the common logs available at the tomcat's log directory, there
is a log in case of problems written by equinox at '<path to your tomcat
installation>\work\Catalina\localhost\<RAP
application>\eclipse\workspace\.metadata\.log'

This is the content of my build.properties :

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
.,\
plugin.xml,\
web/,\
plugin.properties

The web/ folder contains all the web stuff like jsp and WEB-INF folder.

The log from catalina just show the Tomcat startup process and no .log
file produced under .metadata folder.

Hi,

at the moment I'm running a little bit out of options. What is the exact
URL you are using to access the application on tomcat?

The code to access the servlet is like the following :

public void createPartControl(Composite parent)
{
...
browser.setUrl("/fes?mode=login");
...
}

One other possibility crossed in my mind, is it possible that I include
too many plugin jars in the feature.xml that interferes with Tomcat's ?

Here's our list of plugins in the feature.xml:

org.eclipse.equinox.http.registry
org.eclipse.core.contenttype
org.eclipse.equinox.registry
org.eclipse.rap.rwt
org.eclipse.core.runtime.compatibility.auth
org.eclipse.osgi
org.eclipse.rap.ui
org.eclipse.rap.ui.forms
org.eclipse.rap.ui.workbench
org.eclipse.core.jobs
org.apache.commons.logging
org.eclipse.equinox.common
org.eclipse.rap.ui.views
com.farbeyond.ui
org.eclipse.core.commands
org.eclipse.core.runtime
org.eclipse.core.expressions
org.eclipse.rap.jface
org.eclipse.equinox.app
org.eclipse.equinox.preferences
org.apache.commons.el
org.eclipse.osgi.services
org.eclipse.equinox.http.servlet
com.farbeyond.core
org.eclipse.equinox.http.servletbridge
org.eclipse.update.configurator
javax.servlet.jsp
org.eclipse.equinox.jsp.jasper.registry
org.eclipse.equinox.jsp.jasper
org.apache.jasper

Hi again,

this reminds me at a thread about the file upload widget that uses a
seperate servlet for the actual upload. A similar problem was reported
and a nice guy proposed a solution which would adapted to your case look
like this:

String application = RWT.getRequest().getContextPath();
application = application.trim();
browser.setUrl(application + "/fes?mode=login");

Maybe this helps in your case too.

Ciao

Works like a charm.

Thank you so much.
