Help setting up a Rest service.

Thanks.  I can see the users setup in the tomcat-users file...

this is working now, but when I make a request to the URL that i have set up, I get the following:

405 Method Not Allowed

the method is GET, which is what I have exposed and set up in the defined services?

Cheers,

Paul.

Hi,

none of the url's you suggested worked.  if I look in the Server monitor (as screen shot) it says the url is http://localhost:8980/oerm/applications/testRestService/

I'm totally lost here...

Paul.

Hi Paul,

If the application/service is deployed properly to OE Webserver (Tomcat) then invoking http://localhost:8980/testRestService/rest should result in list of all available RESTful services (in this case http://localhost:8980/testRestService/rest/testRestService?_wadl) and from this section you can access the actual WADL file which will show complete information of the service (like URL, resources).

For more information on the REST URI construction please refer 'Understanding REST Web application URI construction' section in this link

The URL shown in the Server monitor view in PDS OE was pointing to wrong URL in 11.3 version and was addressed in 11.3.1 release.

Thanks and Regards,

Anil Kumar.

Paul,

You are being mislead by the information contained in the server monitor's 'REST service URL'.   It confused me also.  The URL field's value will not physically exist in the web server ( at least not in any of my REST projects )

Like Irfan said, the 'oerm' web application is a remote management agent (displayed as 'restmgr1') and does not contain any of the REST services you create in your project.   When you create a REST service in your project and the development studio publishes your service (using 'restmg1') it does so by creating a new web application and deploying it to the web server using the REST service interface's name.

From the screen shot I see the name of your REST service interface is 'testRestService', which will produce and deploy a web application named 'testRestServcie'.   The URL to access your new REST service web application would be:

    http://localhost:8980/testRestService

I generally do an initial manual test to see if the web application ended up where I would expect it and will it start and run:

a) do a GET on 'http://localhost:8980/testRestService and see if it will return anything

b) do a GET on ''http://localhost:8980/testRestService/rest/'  and see if anything is returned

You want to get a 200 response from b) before proceeding further.   Do note that b) can return success, but does not mean that your REST web application is actually able to connect to the AppServer.   For AppServer connection testing you have to access one of your web application's resources that is mapped to a class/procedure in the AppServer.

Try that and see if you get further.

Hi Success!!

I had 2 issues.  one was that I needed to edit the web.xml file to specify which security method to use.  Now this is working, if I hit the url:

http://localhost:8980/testRestService/rest/testRestService?_wadl

I get the following output:

<application xmlns="wadl.dev.java.net/.../02" xmlns:xs="www.w3.org/.../XMLSchema">

<grammars/>

<resources base="http://localhost:8980/testRestService/rest/testRestService">

<resource path="/randomNumber">

<method name="GET">

<response status="204"/>

</method>

</resource>

<resource path="/randomNumber2">

<method name="GET">

<response status="204"/>

</method>

</resource>

</resources>

</application>

So my next question is how do I hit the randomNumber resource and get a response?

Thanks for the help.

Paul.

OK, I'm getting somewhere.....

http://localhost:8980/testRestService/rest/testRestService/randomNumber

this produces an error:

{"_errors":[{"_errorMsg":"ERROR condition: randomNumber Singleton object instantiation ended with an ERROR condition. (16819) (7211)","_errorNum":16819}]}

this is from the Rest service log:

more info.  I looked in the appserver log and found this:

Does this mean that it didnt deploy succesfully?  I'm not sure what to do next..

Paul,

You are doing much better.

Just a guess, but I would say there was a deployment problem.   Check the AppServer configuration's PROPATH and verify that the class file(s) are able to be found.

Thanks for the help everyone.  It's working for me now.  I had missed out adding the project directory to the appserver properties/modules, so the code wasn't being deployed!

Does anyone know how the licensing works for this kind of product in a production environment?  is it on a per server basis?

Thanks,

Paul.
