Custom command plugin

[ebaysteve]

I created a custom command plugin on 2.0.8. The plugin was loaded into the plugins directory. When attempting to start the server I receive a plugins.json cannot be found.

Thanks for the info. I am running into one more issue. I have a class that extends from OServerCommandAuthenticatedDbAbstract. I tried to put it in the plugins directory, but I kept getting a ClassNotFound exception. When it was in the plugins directory I also received the following error:

java.lang.ClassCastException: org.kp.tro.cerebro.graph.plugins.orient.CerebroDlpTokenLoader cannot be cast to com.orientechnologies.orient.server.plugin.OServerPlugin

When I moved it into the lib directory the server seemed to start but when I issued the POST, per the config, it responded Command Not Found.

Do you have any examples that show adding a server extension that uses http?

I don't have any, but I'm guessing you're right about moving it to $ORIENTDB_HOME/lib. But don't forget to register it in $ORIENTDB_HOME/config/orientdb-server-config.xml. Something like:

 <listener protocol="http" port-range="2480-2490" ip-address="0.0.0.0">
    <commands>
      <!-- other commands -->
      <command implementation="org.kp.tro.cerebro.graph.plugins.orient.CerebroDlpTokenLoader" pattern="yourPattern">
        <parameters>
          <!-- maybe some params -->
        </parameters>
      </command>
    </commands>
  </listener>

You've probably already seen this.

I was able to follow the tutorial in the docs and came up with this.

I have it working locally as well. Looks like I was specifying the port when I should not have been. I noticed during startup there were a few ports used, 2480 and 2481. When I ran the command on 2481 it worked. Also when I ran it without specifying the port it worked as well.

Thanks for the help. Now on to more coding to get this thing working.

Thanks again for all you help. I am having one more issue trying to execute the custom command from within a Java Application. Are there any code examples of how to properly do this. I keep getting a connection refused error:

HttpClient httpClient = new HttpClient(); httpClient.getState().setCredentials( new AuthScope(null, 80, "OrientDB db-DemoGraph"), new UsernamePasswordCredentials( "root", "password"));

                    int statusCode = httpClient.executeMethod(

postMethod);

I've updated the tutorial with a possible solution.

[jbkielis]

Were you ever able to get this to work? I copied your github example directly and the orientdb server still wouldn't recognize the custom command. It doesn't show any errors in the log so I'm not sure what's going on.

[vitorenesduarte]

@jbkielis Did you follow every step of the tutorial?

[jbkielis]

Yes, I'm running on 2.0.12. Does it work on that?

[vitorenesduarte]

I don't know, but it should. If you don't see the message "INFO new hello command [OServerCommandGetHello]" when starting OrientDB, then the plugin is not properly installed. Did you restart the OrientDB server?

[jbkielis]

As more context, if I put the jar file in the plugins directory, I do get a server error that it couldn't find the class. This indicates to me that it's registered correctly in the server config file. When I move the jar file to the lib directory I no longer get the error, but I still can't seem to access the endpoint. I continually get a 405.

[vitorenesduarte]

Do you see the message when starting the server?

[jbkielis]

When I put the jar file in the plugins directory i see the following: http://i.imgur.com/Jmbjkql.png When I put the jar file in the lib directory I see the following: http://i.imgur.com/MwTGLzd.png

No message that the new command has been registered.

[vitorenesduarte]

Can you share your orientdb-server-config.xml?

[jbkielis]

Sure: https://drive.google.com/file/d/0B15N2OKVN5McX0xPcTVVRzlqaWs/view?usp=sharing

Thanks.

[vitorenesduarte]

How you're calling the endpoint? There's an error?

[jbkielis]

http://serverurl:2480/hello/development/Tom

error is 405 response with: Command not found: hello/development/Tom

[jbkielis]

I can successfully hit the gephi endpoint at: http://serverurl:2480/gephi/ so I don't think the url is bad

[vitorenesduarte]

I'll take a look to this today. I'll let you know.

[jbkielis]

Ah, figured it out! I was using the hello class that was posted on the orientdb tutorial page, which is slightly different than yours. It contains the following: return new String[]{"GET|hello/* POST|hello/*"}; Note the two endpoints that are part of 1 string. That obviously doesn't work, so you have to separate the two commands into separate strings.

Thanks for your help!

[vitorenesduarte]

Glad you worked it out!

Ok, I'm closing this.
