The remote poller is not working when using HTTP, but it works with RMI

Description

After creating a simple testing environment with the latest code from the master branch in order to play with the Remote Poller (following the directions from the Wiki), I noticed that if I start the remote poller with the following command:

/opt/opennms/bin/remote-poller.sh -l RDU -n admin -p admin -g -u http://localhost:8980/opennms-remoting

it doesn't start, but if I execute it using RMI like the following, it works:

./remote-poller.sh -l RDU -n admin -p admin -g -u rmi://localhost/

I found a problem on ~/.opennms/opennms-remote-poller.log, it is related with a missing class:

Fixed on revision 7469bebf7ab2e50d80c0e697e223ee0e21435243 on master.

The problem is that I'm not sure how can I create a JUnit test based on PollerFrontEndIntegrationTest, to initialize a mock servlet context in order to emulate:

http://localhost:8980/opennms-remoting/pollerBackEnd

Alejandro Galue December 14, 2012 at 10:51 AM

Seth told me that the class in question has changed their name on SpringSecurity 3.1. The new name is:

org.springframework.security.remoting.httpinvoker.AuthenticationSimpleHttpInvokerRequestExecutor

The AuthenticationSimpleHttpInvokerRequestExecutor class is referenced in 3 files of the source code:

  • features/remote-poller/src/test/resources/applicationContext-client.xml

  • opennms-services/src/main/resources/META-INF/opennms/applicationContext-remotePollerBackEnd-http.xml

  • opennms-services/src/main/resources/META-INF/opennms/applicationContext-remotePollerBackEnd-https.xml

Inside the first XML the classname is correct, but on the last two, the class is not correct.

After fixing those files, the remote poller started to work again with HTTP. So I'll try to create a JUnit test to verify those context files in order to be able to detect problems on future upgrades.

This only affects master (i.e., 1.11.x), on 1.10.x it works as expected. The only difference is that master is using a new version of Spring Security (if I recall correctly).
