Hello Everyone, i am trying to develop a simple analysis engine component which should make use of an external resource.I followed the example 6 from the UIMA tutorials and my tests run without any problems: The external resource is loaded, the analysis engine uses the information stored in the external resource and produces correct output. However, after I packed the the component into a PEAR and then tried to install it, the verification process throws the ResourceInitializationException, saying that my external resource implementation class does not implement the org.apache.uima.resource.SharedResourceObject (even though it does). The fragment in the code where the error is thrown is in org.apache.uima.resource.impl.ResourceManager_impl.java line 607. During the debugging I could figure out that if the Application ClassLoader is used (this is the case when instantiating the component) to load the external resource implementation class, then there is no error. However when the UIMA extension ClassLoader is used then the error is thrown(this is the case when verifying the component). I also checked that all the needed jars are included and that the class path is correct. Thanks in advance for your help. Cheers, Sergii
