Exception while loading model using FileManager.get().loadModel("file:xyz.n3")

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a N3/RDF file with a model.
2. Load this model using AndroJena specifically these lines of code:
Model model = FileManager.get().loadModel("file:xyz.n3");   
3. Model should be loaded and "model" object should be ready to use.

What is the expected output? What do you see instead?
Model should be loaded and "model" object should be ready to use without any 
exceptions. It throws "java.lang.NoClassDefFoundError" exception for 
com.hp.hpl.jena.util.FileManager.

What version of the product are you using? On what operating system?
Windows Vista, latest AndroJena

Original issue reported on code.google.com by pamjag...@gmail.com on 16 Nov 2010 at 10:19

Hi pamjagtap,
you get this error because your Android app doesn't reference the 
androjena_0.2.jar library (and possibly other required libraries): that's why 
the bytecode verifier cannot resolve the com.hp.hpl.jena.util.FileManager 
class, thus the NoClassDefFoundException.
Please make sure that all the libraries listed below are referenced and 
packaged with your application:

- androjena_0.2.jar
- icu4j-3.4.4.jar
- iri-0.7.jar
- slf4j-android-1.6.1-RC1.jar

If you're using Eclipse, just make sure that those libraries are correctly 
referenced in the Libraries tab inside the Java Build Path project properties 
(follow the instructions in the README file contained in the androjena release 
package)

Please let me know if this solves the issue; if it doesn't, please add a 
comment to this issue with the following application files attached (when 
available):
- the portion of your source code where the exception is thrown
- AndroidManifest.xml
- .classpath (it's an Eclipse file in the root of your project)
- default.properties

Thanks,
lorenzo

I have filed these issues and henceforth I will use this ID to comment.

Please go over Issue 6 because of which I had to remove "icu4j-3.4.4.jar" from 
build path. I understand fixing that issue might resolve this and issue 5 
automatically. Still I have attached application files which can be useful for 
you.

-- Source Code:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        
        subjectString.append("****START********");
        Model model =     FileManager.get().loadModel("http://localhost/rules/SchoolModel.n3"); 
}

Attachments:

• .classpath
• AndroidManifest.xml
• default.properties

Issue 6 solution probably works for this issue too. If not, it'll be reopened.
