I have recently been trying out uploading a custom process through the WPS Admin console as per the tutorial, which appears to have worked fine, however when I try to access the GetCapabilities functionality I am presented with the following message:
HTTP Status 500 - Servlet.init() for servlet wpsServlet threw exception
type Exception report
message Servlet.init() for servlet wpsServlet threw exception
description The server encountered an internal error that prevented it from fulfilling this request.
note The full stack trace of the root cause is available in the Apache Tomcat/7.0.52 (Ubuntu) logs.
Has anyone seen this message before? This custom process has worked previously and no code has been changed, it extends AbstractSelfDescribingAlgorithm and the .java and class files are in the classes folder under WEB-INF. The custom process is also displayed when I click on "Algorithm Repositories" in the WPS Admin console.
