[jira] Created: (SYNAPSE-431) Problem when passing a String array
through a proxy service
Problem when passing a String array through a proxy service
-----------------------------------------------------------
Key: SYNAPSE-431
URL: https://issues.apache.org/jira/browse/SYNAPSE-431
Project: Synapse
Issue Type: Bug
Affects Versions: 1.1.1
Reporter: sumedha rubasinghe
I have a proxy service(MyServiceProxy), which calls an Axis2 Service.
My Axis Service(POJO) implementation is as follows:
MyService{
public String dosomething(String[] params)
....
....
}
}
Point to note is the operation which accepts a String array.
I issue a REST call to this service using following URL (going directly to Axis Server) & it works.
http://<IP>:6060/services/MyService/dosomething?params=ABC¶ms=XYZ¶ms=PQR
Take a note of same http parameter name(params) being used with different values. This is how Axis2 REST implementation allows us to pass values to an array of simple types.
Now I call this service through my proxy service as follows.
http://<IP>:8080/services/MyServiceProxy/dosomething?params=ABC¶ms=XYZ¶ms=PQR
Now the service implementation only gets value "PQR". First two values (ABC & XYZ) are not coming into Axis2 Service level through Proxy Service.

-----------------------------------------
This seems to be a problem with the HTTP NIO listener. I have a test case that confirms this.

Andreas Veithen commented on SYNAPSE-431:
-----------------------------------------
Looking at the code, the complete explanation of this issue seems to be as follows:
* For GET requests, Axis' HTTP transport probably uses BuilderUtil.buildsoapMessage. If schema information is available for the service, this method supports multiple values for the same parameter. If no schema information is available, BuilderUtil.createSOAPMessageWithoutSchema is used, which only takes into account the first value. This should explains why your Axis2 service (which probably has a schema) works with multiple values, while my test case (which doesn't use a schema) does not.
* As can be seen from RESTUtil.createEnvelopeFromGetRequest, the NIO HTTP transport doesn't use BuilderUtil.buildsoapMessage and implements an algorithm similar to BuilderUtil.createSOAPMessageWithoutSchema. Therefore it doesn't support multiple values even if there is schema information.
I believe that RESTUtil.createEnvelopeFromGetRequest should be changed to use BuilderUtil.buildsoapMessage in order to make sure that the behavior of the different HTTP transports is consistent. For your proxy service, you would then have two options:
* Use publishWSDL to make sure that the proxy service has schema information and check if that solves the problem.
* File a JIRA for Axis2 to change the behavior of BuilderUtil.createSOAPMessageWithoutSchema to support multiple values.

Andreas Veithen commented on SYNAPSE-431:
-----------------------------------------
I ran my test case against Axis' blocking HTTP transport and it shows the same behavior. I know that the way Axis transforms a REST request into a SOAP infoset depends on the presence of a schema in the operation description. Do you use a publishWSDL element on your proxy?
