Eclipse RCP bundleresource urls returned for UimaContext.getResourceURL method

Hi All,

This is really an Eclipse RCP specific question. The problem is that when any of the TAEs use
UIMAContext.getResourceURL method to get any of their resources, and the TAE is being run from within an
Eclipse RCP application, the returned URLs are of the form bundleresource://188/path/to/your/resource

This is not understood by the remaining TAE code which is expecting a File:// URL.

This occurs because the Eclipse ClassLoader does this URL mangling before returning the correct URL.

The exact place where this call to the classloader takes place is in org.apache.uima.resource.RelativePathResolver.resolveRelativePath()

Has anybody faced this problem before and knows of a clean solution?

Based on my research I see two possible solutions:

1.       Explicitly set the classloader that is used by the  RelativePathResolver . By using our own classloader
and not the Eclipse classloader we completely sidestep the problem.

2.       Modify the RelativePathResolver to undo the bundleresource URL coding and return a normal file:// url .
This would require using a custom uima-core.jar which is not very attractive.

Any ideas/suggestions?

Re: Webservices

Hi Radwen,
what do you mean for "a webservice for the whole application"?
Are you meaning that you want to webserve an aggregate AE or the whole
package (consisting of non-UIMA stuff too)?

Re: Webservices

Hi Tommaso,

Yes and no, By webservice I mean the whole application , the entire CPE, is
it possible to turn it into a webservice ?

Re: Webservices

CPM is an embeddable component which you may wrap as a service.

Re: Webservices

Thank you Jaroslaw,

Ok that's great but well neither on the web nor even in UIMA doc (may be i'm
wrong) there is a clear documentation for that , do you have any link or
documentation that serves as a start point so that I can follow it ?

Thank you

Radwen

Re: Webservices

Look in: UIMA Tutorial and Developers' Guides

Section 2.3. Running a CPE from Your Own Java Application

Let me know if you need further clarification. As previously mentioned
the CPE can be embedded in your application. You can create an instance
of it in your own application using CPM's API. You can initialize it from a
static descriptor or you can create the descriptor at runtime using
available
API. The programmatic approach is documented in

3.3.2. Configuring a Collection Processing Engine
Descriptor Programmatically

of the UIMA Tutorial and Developer's Guide

Hope that this helps.

Problem installing UIMA-AS Deployment Descriptor Ed. for Eclipse

Matthias,
Could you please describe the steps that you did to install the Deployment
Descriptor Editor since the log said that "Missing requirement: UIMA-AS
Deployment Descriptor Editor 2.2.2.incubating".

Re: Problem installing UIMA-AS Deployment Descriptor Ed. for Eclipse

Hi Tong,

OK, that was too few information.

I was trying to install the editor from the "Help > Install New 
Software" dialog using the eclipse update site 
"http://www.apache.org/dist/incubator/uima/eclipse-update-site/".

The "UIMA Runtime" and "UIMA tools" were already installed both in 
version 2.2.2.incubating. Then I chose "UIMA-AS Deployment Descriptor 
Editor" clicked "Next > Finish > OK".

The install operation seems to do something, but I always end up with 
the error message that I sent.

Thanks for checking
Matthias
