             Summary: Reading resource via Classloader
                 Key: OLINGO-312
                 URL: https://issues.apache.org/jira/browse/OLINGO-312
             Project: Olingo
          Issue Type: Bug
          Components: odata2-core
    Affects Versions: V2 1.2.0
            Reporter: Giacomo Pati


While many servlet-containers tested by me work fine with construct below, WebSphere 8 doesn't like it and returns null for the resources path requested (it's actually outside of Classloader managed filesystem area, which I would consider being bad practice):
{code}
InputStream is = JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream("../../" + mappingModelName);
{code}

As the class in question (JPAEdmMappingModelService) doesn't have access to the servlet context to properly read a file from the web space area I'd suggest (also for backwards compatibility reasons) to add this to the code as shown in the following patch:
{code}
@@ -195,6 +195,9 @@ public class JPAEdmMappingModelService implements JPAEdmMappingModelAccess {

   protected InputStream loadMappingModelInputStream() {
     InputStream is = JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream("../../" + mappingModelName);
+      if(is == null) {
+          is = JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream(mappingModelName);
+      }

     return is;
{code}

which would alternatively allow to put the mapping file into the WEB-INF/classes folder.
