No Such Method Error
Hi ALL
I have migrated from Jena 2.11 to Jena 3.1.0 Lately. After modifying my code to fit JENA 3.1.0 I have gotten this error exception:
java.lang.NoSuchMethodError: org.apache.jena.atlas.lib.Cache.getIfPresent(Ljava/lang/Object;)Ljava/lang/Object;
After searching the jena-users mailing list, I found that it had to do with different versions of Jean being found in the classpath or one of jena libraries in my code calling an old class it didn't have the method. I tried with my best knowledge (which is not enough) to find a solution, but I have failed. the only thing I could find is that the method wich are responsible for this error in my could is:
OntModel ontModel = ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM, null);
Could any one help me please.
Thanks in Advance
Abdul

Thanks Andy for answring my emails.
It is solved. It is web application. I just cleaned and rebuilt the application.

There is some incompatible jar on the runtime execution classpath.

In 2.11, org.apache.jena.atlas.lib.Cache was in jena-arq. In Jena 3.1.0,
it is in jena-base.
Some org.apache.jena.atlas.lib.Cache is on the classpath, maybe multiple
times. The first one found is not compatible though.
Something is still wrong with the setup but theer is no evidence as to
what in the emails.

Thanks AndySorry, it could be a basic question. I could not understand what I have done wrong to make my project call old jena library. I removed all jena 2.11 libraries from my project but I still get this exception.
