Hi Andrus, Hi Aristedes! Thanks for your quick answers!
Now my 'tutorial' and my problem follows. After downloading the remote example in 2.0.4 I build the client with the following deps: cayenne-client-nodeps other dependencies from [1] and the server with: cayenne.jar derby*.jar (grabbed the latest version from www) the context I set is: path="/" before I started the server I created the schema within the DB: 1. Start the CayenneModeler 2. Open the cayenne.xml within src/tutorials/quick-start-rop/cayenne-tutorial/src 3. Upgrade from version 1.1 4. Go to tools->preferences->local datasource->new jdbc:derby:/yourPathHere/testdb;create=true add derby to the classpath; no login or password necessary 5. Validating Project should be okay. 6. Finally create the schema via: Tools->Generate Database Schema (select UntitledDomainNode before) Now close the modeler under windows and start the webapp with jetty or reconfigure the client authentication for tomcat otherwise you will get sth. like [2]. You should see a simple page with "Artists:No artists found" if you go to localhost:8080 But the client quits now with an exception [3] - nothing happend to the server. Whats wrong? Should I use an older hessian jar or sth. like this? It seems to me that also other people had problems with this [4]. I will try now the strandz.org example ... Regards, Peter. [1] http://www.strandz.org/rosterAppJars.zip only some jars are necessary ... And for hessian I tried 3.0.13, 3.0.20 and 3.1.6 [2] java.net.HttpRetryException: cannot retry due to server authentication, in streaming mode at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1062) [3] java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/cayenne-service at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1241) [4] http://issues.apache.org/jira/browse/CAY-627
