Subject Re: [jira] Created: (UIMA-1027) Classes from uima-document-annotator.jar are not in Eclipse plugin
Date Tue, 13 May 2008 21:57:52 GMT
Hi Mikhail,

We appreciate your input - I find the OSGi stuff complex.  I've 
attempted to reply to your concerns below, but please respond if I'm not 
understanding, or have perhaps misunderstood some detail about how OSGi 
/ Eclipse is supposed to work :-)

2.2.2 has jars unzipped. 
Yes.  This was done due to the discussion on this thread:  
http://www.mail-archive.com/uima-dev@incubator.apache.org/msg06246.html.  
It seemed to be necessary.  Is this causing a problem for you?

This jar has the JCas cover class for the UIMA DocumentAnnotation type.  
But we don't include this in the plugin so that applications which 
extend the DocumentAnnotation type with additional UIMA 'features' can 
generate a different JCas cover class for the DocumentAnnotation type 
and substitute their own version of this class.  For the background 
discussion on this, see 
http://incubator.apache.org/uima/downloads/releaseDocs/2.2.2-incubating/docs/html/references/references.html#ugr.ref.jcas.documentannotation_issues

At the end of comments for UIMA-400 is the point about 
uimaj-jcas-builtin-types.jar (which previously held the 
DocumentAnnotation JCas cover class) is listed in the manifest, but not 
present in the plugin.  The comment there says it is fixed under 
UIMA-549.  But that fix didn't add the jar - rather the manifest entry 
for uimaj-jcas-builtin-types.jar was removed. 

Can you add your own version of the JCas cover types for 
DocumentAnnotation in your particular use case?

i.e. the same package is exported and imported in manifest. Probably, it's caused by the same
missing classes from that jar.

I'm not sure this is an error - isn't it common for a bundle to both 
export and import a package?  Section 3.5.6 of the OSGi  r4.core 
documentation says it's quite common for bundles to both import and 
export the same package.  Is this causing some particular trouble for you?

Thanks.  -Marshall
