Hello All,

I wanted to add support for Online help. I've read a number of posts
here. I'm neither an rcp expert.

Here is what I've done:

1. Added following plugins to target platform:

javax.servlet.jsp_2.0.0.v200806031607.jar
org.apache.commons.el_1.0.0.v200806031608.jar
org.apache.jasper_5.5.17.v200806031609.jar
org.apache.lucene.analysis_1.9.1.v20080530-1600.jar
org.apache.lucene_1.9.1.v20080530-1600.jar
org.eclipse.equinox.jsp.jasper.registry_1.0.0.v20080427-0830 .jar
org.eclipse.equinox.jsp.jasper_1.0.100.v20080427-0830.jar
org.eclipse.help.appserver_3.1.300.v20080507.jar
org.eclipse.help.base_3.3.100.v20080617.jar
org.eclipse.help.webapp_3.3.100.v20080528.jar
org.eclipse.help_3.3.100.v20080610.jar

Included them in debug configuration.

2. Made test project with two plugins. One containing help and the other
is for code. In the plugin.xml:

<extension
point="org.eclipse.equinox.http.registry.httpcontexts">
<httpcontext
id="popopo">
<resource-mapping
path="/">
</resource-mapping>
</httpcontext>
</extension>

<extension
point="org.eclipse.equinox.http.registry.resources">
<resource
alias="/"
base-name="/"
httpcontextId="popopo">
</resource>
</extension>

<extension
point="org.eclipse.equinox.http.registry.servlets">
<servlet
alias="/control"
class="org.eclipse.help.internal.webapp.servlet.ControlServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/content"
class="org.eclipse.help.internal.webapp.servlet.ContentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/topic"
class="org.eclipse.help.internal.webapp.servlet.ContentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/nftopic"
class="org.eclipse.help.internal.webapp.servlet.ContentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/ntopic"
class="org.eclipse.help.internal.webapp.servlet.ContentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/rtopic"
class="org.eclipse.help.internal.webapp.servlet.ContentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/nav"
class="org.eclipse.help.internal.webapp.servlet.NavServlet"
httpcontextId="popopo">
</servlet>
<servlet
alias="/livehelp"

class="org.eclipse.help.internal.webapp.servlet.LiveHelpServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/toc"
class="org.eclipse.help.internal.webapp.servlet.TocServlet"
httpcontextId="popopo">
</servlet>
<servlet
alias="/tocfragment"

class="org.eclipse.help.internal.webapp.servlet.TocFragmentServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/index"
class="org.eclipse.help.internal.webapp.servlet.IndexServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/indexfragment"

class=" org.eclipse.help.internal.webapp.servlet.IndexFragmentServle t "
httpcontextId="popopo">
</servlet>
<servlet
alias="/search"
class="org.eclipse.help.internal.webapp.servlet.SearchServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/context"
class="org.eclipse.help.internal.webapp.servlet.ContextServlet "
httpcontextId="popopo">
</servlet>
<servlet
alias="/extension"

class="org.eclipse.help.internal.webapp.servlet.ExtensionServlet "
httpcontextId="popopo">
</servlet>

<servlet
alias="/*.jsp"

class="org.eclipse.equinox.jsp.jasper.registry.JSPFactory:/ "
load-on-startup="true"
httpcontextId="popopo">
</servlet>

</extension>

3. Added a button event listener to pop up the help contents:

public void handleEvent(Event event)
{
if (event.widget == btTestCall)
{
String helpURL = "http://{0}:{1}/index.jsp";
Object[] param = new Object[]{
RWT.getRequest().getServerName(),
String.valueOf( RWT.getRequest().getServerPort() )
};
Shell shell = new Shell( Display.getDefault() );
shell.setLayout( new FillLayout() );
Browser brwsr = new Browser( shell, SWT.NONE );
shell.setBounds( 20, 20, 400, 400 );
brwsr.setUrl( MessageFormat.format( helpURL, param ) );
shell.open();

}
}

4. The dialog has shown this:

HTTP ERROR: 404

/index.jsp

RequestURI=/index.jsp

Powered by Jetty://

Also tried http://localhost:9090/index.jsp and got the same result.

By the way, http://localhost:9090/index gave me this:

<indexContributions>

<indexContribution id="/myplugin.help/index.xml" locale="ru_RU">
<index/>
</indexContribution>
</indexContributions>

Is it fine?

Thanks

Hi Dmitry,

not sure what is going wrong with your setup. I tried a very simple
setup which works fine. It is attached to this post.

It comes with a launch configuration and should run as is if you
work against CVS. Otherwise you will have to adjust the launch
configuration. Please read the included readme.txt for some more
details.
