RE: Re: NPE when using WADL extension auto transform to HTML feature
Any news ? I'am still using restlet 2.1-M3 because all newer version of restlet including the lastest 2.1.1 have the same bug. Regards, Hello Jon, Paul, I think there is a regression introduced during the application of a patch. I keep you informed quickly. Best regards, Thierry Boileau I'm having this same issue: just trying to retrieve url/method=OPTIONS on my WadlApplication derivative gives the following: SEVERE: An exception occured writing the response entity java.lang.NullPointerException at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:642) at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:1273) at org.apache.xalan.transformer.TransformerImpl.transform(TransformerImpl.java:1251) at org.restlet.ext.xml.TransformRepresentation.transform(TransformRepresentation.java:572) at org.restlet.ext.xml.TransformRepresentation.write(TransformRepresentation.java:589) at org.restlet.ext.xml.TransformRepresentation.write(TransformRepresentation.java:599) at org.restlet.representation.CharacterRepresentation.write(CharacterRepresentation.java:76) at org.restlet.engine.adapter.ServerCall.writeResponseBody(ServerCall.java:509) at org.restlet.engine.adapter.ServerCall.sendResponse(ServerCall.java:453) at org.restlet.ext.servlet.internal.ServletCall.sendResponse(ServletCall.java:459) Requesting JSON works fine, of course.

Re: NPE when using WADL extension auto transform to HTML feature
Also forgot to mention that I do have the XML extension on the classpath and debugging indicates that the Source object is the null object in the transform method (in case that wasn't obvious enough). I saw a related thread about OSGi bundles not being able to find the wadl2html.xslt file but I can see that it is packaged with the WADL extension. -- View this message in context: http://restlet-discuss.1400322.n2.nabble.com/NPE-when-using-WADL-extension-auto-transform-to-HTML-feature-tp7578165p7578166.html Sent from the Restlet Discuss mailing list archive at Nabble.com. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2974678
Re: NPE when using WADL extension auto transform to HTML feature
I just now saw a duplicate of this issue here: http://restlet-discuss.1400322.n2.nabble.com/NullPointerException-when-using-WADL-HTML-representation-td7526952.html I hadn't seen that earlier when I posted but it appears to be the same exact issue. In a similar vein, I saw a comment from some time ago while I was searching around for more info on this wherein Jerome mentioned that WadlResource was slated to be deprecated. Is that still the case Jerome? -- View this message in context: http://restlet-discuss.1400322.n2.nabble.com/NPE-when-using-WADL-extension-auto-transform-to-HTML-feature-tp7578165p7578168.html Sent from the Restlet Discuss mailing list archive at Nabble.com. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2974726
