Re: Using the UIMA plugins in an RCP application

[Jörn Kottmann]

Hello,

the problem here could be that you do not have the  
org.eclipse.platform.plugin
loaded in your RCP application.
Hope this helps,
Jörn

Hi All,

I am writing an Eclipse RCP application and would like to use the UIMA
component descriptor editor plugin within my RCP application to edit  
the
UIMA descriptor files. I added them as dependencies and the editor  
shows
up as an option under "Open with..." menu when I right click on an xml
file.



The problem is when I do try to open it, the editor fails to  
initialize
and thows an exception.



Here is the root cause:



Caused by: java.lang.NullPointerException

           at
org 
.apache.uima.taeconfigurator.TAEConfiguratorPlugin.<clinit>(TAEConfig
uratorPlugin.java:74)





Here is the code around line 74 in TAEConfiguratorPlugin.java:

======================

 static {

   Bundle bundle = Platform.getBundle("org.eclipse.platform");

   String versionString = (String) bundle.getHeaders().get(  --- this
is line 74

           org.osgi.framework.Constants.BUNDLE_VERSION);

   PluginVersionIdentifier version = new
PluginVersionIdentifier(versionString);

   eclipseVersionMajor = version.getMajorComponent();

   eclipseVersionMinor = version.getMinorComponent();

   is30version = eclipseVersionMajor == 3 && eclipseVersionMinor == 0;

 }

======================



I am using UIMA 2.2.1. with Eclipse 3.3



Any help is much appreciated.



Thanks,

Girish
