Hi
I get an error when deploying a model as follows

Could not access HTTP invoker remote service at [http ://localhost:8081/dynweb7/remoting/CarnotUserService]; nested exception is java.io.IOException: Did not receive successful HTTP response: status code = 404, status message = [Not Found]

Any suggestions what this could be (more below)
thanks

Hi Mervyn,

this is a typical error when the remoting services are not available either do to startup problems or due to a wrong URL.

Quick checks:
1. Can you reach the portal's login page at URL http ://localhost:8081/dynweb7/ ? (I'm assuming the port 8081 was intentionally changed from the default 8080).
2. Check the console output or the startup log for exceptions, usually the application or the server never started up successfully
3. Sometimes on Windows there are problems to resolve localhost correctly. Try to use the machines IP address or machine name in the file <project>/ipp-resources/carnot-spring-client.properties which contains this URL.

Regards,

Jan

Hi Jan

1. No I cannot reach the portal login page
2. The server does start, (I get a Tomcat delivered 404 page), but there are a lot of errors:

3. The file the file <project>/ipp-resources/carnot-spring-client.properties did seem to be corrupt, the path indicated was Carnot.Spring.RemotingUrl=http\://localhost\:8080/dynweb7/remoting

Changing this to various alternatives, (and various restarts/redploys) did not solve it

(strange that the first time I set Stardust/Eclipse/Tomcat up and deployed a model, it all worked fine)

thanks
Merv

Mervyn,

were you able to resolve the problems in the end? Did you try recreating the Rapid Application setup (Tomcat/Dynamic Web Project)?

Regards,

Jan

Hi Mervyn,

Can you check if you have an entry in your tomcat/server.xml. This should look something like this

<Resource auth="Container" defaultAutoCommit="false" driverClassName="org.apache.derby.jdbc.EmbeddedDriver" maxActive="50" maxIdle="10" maxWait="5000" name="AuditTrail.DataSource" password="default_password" type="javax.sql.DataSource" url="jdbc:derby:default_db" username="default_username"/>

Note: I've replaced actual instance names with default_*

Also when you start the tomcat server, can you check if you get any error looking for a file carnot-audittrail.properties.
