I've developed a small application with Apache Cayenne using Cayenne Web Service. The application was developed on Eclipse using the Jetty plugin. This was the only way to make it work, so I can start writing code. The problem is when I try to deploy the application using a standalone Jetty server, the client java application throws an exception for this code (and any example from online documentation): ClientConnection connection = new HessianConnection( "http://localhost:8080/reselleri/cayenne-service";); DataChannel channel = new ClientChannel(connection); ObjectContext context = new CayenneContext(channel);
SelectQuery select = new SelectQuery(Administrator.class); // this is where the exception is thrown ! List rezultat = context.performQuery(select); If I run the server web service inside Eclipse Jetty Plugin, it works perfectly: INFO QueryLogger: Detected and installed adapter: org.apache.cayenne.dba.derby.DerbyAdapter INFO QueryLogger: SELECT t0.denumire, t0.parola, t0.username, t0.id FROM ADMINISTRATOR t0 - prepared in 47 ms. INFO QueryLogger: === returned 2 rows. - took 1344 ms. If I run the service with standalone Jetty or Tomcat (I've tried many versions, even for Cayenne+dependencies, it' the same) the client won't work, as you can see in the exception output below. I can mention that while running Tomcat/Jetty, I don't have problems running servlets using Cayenne on server side. Only the client has problems. It seems that for some reason, the cayenne web service+client works only with Jetty plugin. What can I do ? Thank you very much for your attention. TristanBelow is the stdout from client, the connection is fine, but I can't perform queries.19.06.2009 12:21:08 org.apache.cayenne.remote.hessian.HessianConnection connect INFO: Connecting to [http://localhost:8080/reselleri/cayenne-service] - dedicated session. 19.06.2009 12:21:09 org.apache.cayenne.remote.hessian.HessianConnection connect INFO: === Connected, session: org.apache.cayenne.remote.remotesess...@1de3f2d[sessionid=863r7x7r6ilu] - took 1125 ms. 19.06.2009 12:21:09 org.apache.cayenne.remote.BaseConnection sendMessage INFO: --- Message 0: Bootstrap 19.06.2009 12:21:09 org.apache.cayenne.remote.BaseConnection sendMessage INFO: === Message 0: Bootstrap done - took 391 ms. 19.06.2009 12:21:09 org.apache.cayenne.remote.BaseConnection sendMessage INFO: --- Message 1: Query com.caucho.hessian.io.HessianProtocolException: at com.caucho.hessian.client.HessianProxy.invoke(HessianProxy.java) at $Proxy0.processMessage(Unknown Source) at org.apache.cayenne.remote.hessian.HessianConnection.doSendMessage(HessianConnection.java:140) at org.apache.cayenne.remote.BaseConnection.sendMessage(BaseConnection.java:73) at org.apache.cayenne.remote.ClientChannel.send(ClientChannel.java:242) at org.apache.cayenne.remote.ClientChannel.onQuery(ClientChannel.java:88) at org.apache.cayenne.util.ObjectContextQueryAction.runQuery(ObjectContextQueryAction.java:217) at org.apache.cayenne.CayenneContextQueryAction.execute(CayenneContextQueryAction.java:47) at org.apache.cayenne.CayenneContext.onQuery(CayenneContext.java:290) at org.apache.cayenne.CayenneContext.performQuery(CayenneContext.java:279) at com.distributie.client.FormPrincipal.Connect(FormPrincipal.java:170) at com.distributie.client.FormPrincipal.<init>(FormPrincipal.java:145) ----------skipped lines ------------
