Patch v1.0 for 3.4.2p eyuen7: review+

Description Dev Deviskec CLA 2013-03-10 18:41:24 EDT 
Eclipse JUNO SR2 release broke the HTTP Preview server. It worked until now (i was working on SR1). 

I'm running on Ubuntu 12.10 64.bit java version "1.7.0_15", OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.10.1), OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode))

and

Eclipse Java EE IDE for Web Developers, Version: Juno Service Release 2 Build id: 20130225-0426)

The error I get is as follow (the jetty server does not start at all):

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/webapp/WebAppContext

Patch v1.0

In org.eclipse.wst.server.preview.adapter.internal.core.PreviewLaunchConfigurationDelegate, the REQUIRED_BUNDLE_IDS list is missing "org.eclipse.jetty.webapp" and "org.eclipse.jetty.servlet"

After adding these two plug-ins to the REQUIRED_BUNDLE_IDS, the Preview Server can be started properly and I can run a static web page.

Comment 3 Dev Deviskec CLA 2013-03-14 05:12:32 EDT 
Thank you very much for the fix! Will test as soon as I can, think I need to recompile the module though and I don't have the source code checked out currently.

Patch v1.0 for 3.4.2p

I have created a patch based on 3.4.2p

I ran the following test:
1. Ensured the HTTP Preview server can be started successfully
2. Ensured that my static web project can be published and the HTML file can be run
Comment 6 Steven Hung CLA 2013-04-30 11:18:31 EDT 
Resolving, committed changes to 3.4.2p.

Hello Steven, thank you for this patch.
Could you please direct me to instructions on how to apply patches to my eclipse?

Thanks in advance.
Leo.
Comment 9 Steven Hung CLA 2014-02-27 10:21:51 EST 
Leo, which Eclipse are you using? Is it Juno SR2?

If you are using Juno SR2, you apply the patch by extracting the contents of the zip into your eclipse directory. You want the plugins and features in the zip to add to the plugins and features in your eclipse directory.
