Thank you for reading. I tried for serveral days but I cannot find why this is going wrong.

I have build a standard Tomcat v10.0.2 server. I have setup my Eclipse with java jdk 11 and using GWT 2.9.0

I Generated the sample code of GWT 2.9.0 with java jdk 11. I compile this succes fully. I deployed the war file to the tomcat server, but then it give me a RPC 404 error. 

According to the tutorials which I read on this should all be in the right place, right coded...still I got the a 404 error on a RPC call.. which means the service isn't there where it suppose to be.

Could somebody please point me in the right direction... 

I already tried. <url-pattern>/local.appletree.Banana/greet</url-pattern> but I have a rename-to in the gwt.xml so banana should be allright.

Thank you in advance Michel.
