Is it RAP still working with Juno 4.2.2 [message #1050019]

Eclipse User

Hello,

Am I the only one who cannot make RAP work ?

I am developping an Eclipse RCP/RAP (single sourcing) application since 2 years. I add to install a new version of Eclipse platform yesterday. My RAP software run, the Jetty server too, but I constantly get error:

HTTP ERROR: 404
Problem accessing /rapdemo/rap. Reason: 

    ProxyServlet: /rapdemo/rap

No message in the Console.

I just did the test. I download the last Eclipse, install RAP target platform, add org.eclipse.rap.demo plugin, and launch it through RAP Workbench Demo launch configuration (so basically I perform the RAP Quick tour) ... and 404 ...

The worst is that I get the same problem on my Windows 7 computer and the Mac Book Pro (Mountain Lion). So my question: Does new RAP build actually works ?

Thanks for your help!

It happens to me a lot, just refresh the browser. i think it is because the browser gets there before jetty is fully up and running. Never happens once it is deployed to tomcat.

Yes, this happens because the RAP tooling launches the browser faster than the RAP application can start and be ready to accept requests. See bug 282756[1].

Hi Christophe

If you are getting the same error on refresh also, you can try the below things:

From RAP 2.0,
RAP applications can not be accessed by startup parameter anymore:

http://hostname/webapp/rap?startup=example (OBSOLETE)

Instead of this, every entrypoint must have a dedicated path (servlet name):

http://hostname/webapp/example

If you used to register entrypoints by parameter in your extensions, you have to use the attibute path instead:

<extension point="org.eclipse.rap.ui.entrypoint">
<entrypoint id="example.entrypoint"
class="example.MyEntryPoint"
parameter="example"
path="/example" />
</entrypoint>
</extension>

To make an IApplication available at a certain path, you have to create a separate entrypoint extension and specify the id of the application extension in the new parameter applicationId.

<extension point="org.eclipse.rap.ui.entrypoint">
<entrypoint id="example.application.entrypoint"
applicationId="example.application"
path="/example" />
</entrypoint>
</extension>

for more info, check this http://eclipse.org/rap/noteworthy/2.0/migration-guide/

Please let me know if it helps.
Thanks
Vikas

Hi Christophe,

are you using the RAP 1.5 tools (shipped with Eclipse 4.2.2) with RAP
2.0 (the latest release)? Unfortunately, these version don't work
together. You need to upgrade the RAP tools from the RAP update site in
order to develop and launch RAP 2.0 applications:

Ok perfect! As soon as I put the RAP tools it works! I thought I was already in RAP 2.0, but I was using old RAP 1.5 tools...

Sadly my problem is not totally solved as now I have a reccurent problem:
I install Eclipse, create a new workspace for RAP only application. Use the RAP tutorial. It runs perfectly. Then when I stop Eclipse. I get a crash if I run it again!
Here is the log:
