RAP 1.5 M3 RWT-OSGi integration bundle [message #761953] Wed, 07 December 2011 10:39 Go to next message

Hi,

i use RAP 1.5 M3 to develop a RWT standalone application. The runtime environment is Apache Karaf.
But when i try to start the RWT-OSGI integration bundle i get an error message because the integration bundle imports the package org.osgi.service.http;version="[1.2.1,2.0.0)

Apache Karaf uses Pax Web for this service. Pax web exports this package with the version 1.2. In the "OSGi Service Platform Enterprise Specification,Release 4, Version 4.2" is following example: Import-Package: org.osgi.service.http; version="[1.2,2.0)

Is the version in the RWT-OSGI integration bundle wrong?

Greetings

Peter

Peter,

this looks like an unnecessary constraint in o.e.rap.rwt.osgi. A quick
check after changing the import to [1.2.0,20) didn't show any
difference. We would need to make sure though that there are really no
unwanted side effects.
Would you mind to open a bug [1]?

TIA
Rüdiger

Hi Rüdiger,

tested it on the latest nightly. It is possible to start the bundle now.

Thank you for the quick fix.

Peter

Hi Peter,

I am trying to develop a RAP application. I have Karaf installed but do not know how to create an RWT-OSGI bundle or what files need to go into Karaf's deploy folder. Can you help me?

Thank you
Charles Tubbs

Hi Charles,

i use the org.eclipse.rap.rwt_1.5.0.xxxx.jar and the org.eclipse.rap.rwt.osgi_1.5.0.xx.jar files from the RAP Runtime. This two bundles are contained in the zip file.

But if you have Karaf 2.2.x, you will see a NullPointerException when you access your application. There is a problem with the pax-web component and the way the RAP osgi integration works Sad

I try it with Karaf 3.0.0-SNAPSHOT now, but at the moment without success.

Regards
Peter

would you mind to file a bugzilla that details out the steps you do?
Please also attach the stacktrace.

TIA

Hi Rüdiger,

this is really a bug in pax-web. There is a JIRA for this problem: PAXWEB-303
In Karaf 3.0.0-SNAPSHOT is a newer version of pax-web contained, where this bug is fixed.

But when i call my application only a empty page is displayed. How is the IEntryPoint.createUI() called? In the source of the page i see :

 
if( discoverAjax() ) {
        // rap runtime application
        org.eclipse.rwt.protocol.Processor.processMessage( {
"meta": {},
"operations": [ [ "create", "w1", "rwt.Display" ], [ "call", "w1", "init", {
"rootId": "w1",
"url": "reach"
} ] ]
} );

Should this javascript snippet do the call? My Browser is chrome

Regards
Peter

Peter,

an entry point must be registered with
ApplicationConfiguration#addEntryPoint(). Is your entry point is
executed at all?

Hi Rüdiger,

the pax-web component in Karaf 3.0.0 have a bug on Windows with the Resources. They have a problem with the "\" in the file path, as result the Javascript files from RWT are not loaded.
When this bug is fixed, i hope my entry is executed.

Regards
Peter
