| Absolute path of a resource in the classpath [message #242712] |

Hi there!
I have to find the absolute path (URL) of a resource that lies in a JAR
file in the classpath of a Java project. All I know is the
classpath-relative path of this resource. With pure Java, this can be
done very easy over the classloader like this:
URL absolute =
this.getClass().getClassLoader().getResource("conf/meta-model/MyModel.edsmm ");
Because I need to do this in a plugin, i can't use the classloder. I
have to do this with help of an IJavaProject.
I know there is a way to get resources by iterating over the package
fragments of the project and doing a getNonJavaResources() at the right
fragment, but this is a very complicated solution with several loops,
sub-loops and checks.
Isn't there an easier way to do this? Normally, using eclipse should
make things simpler ;-).
Thanks
Roger

Thank you for the answer Genady.
Hmmm, correct me if I'm wrong. With getResolvedClasspathEntry() I get an
IClasspathEntry holding the resolved path of a given IClasspathEntry.
An IClasspathEntry represents a library, a JAR or a referenced project.
The problem is, that I don't know in which JAR my resource lies. That is
what I try to find out. I only know that I is somewhere in the projects
classpath.
