I have deployed Restful Web Serivce on the server and accessing it from Client application.
I am using JSON to communicate data between services & client.
Normal flow is working perfect.
But,in case of Exception, I am able to receive HTTP STATUS & reason for Exception but not receiving Response Body.
Here is my Exception Handler
#ExceptionHandler(MyException.class)
#ResponseStatus(value=HttpStatus.INTERNAL_SERVER_ERROR,reason="Unable to fetch data")
public #ResponseBody String handle(MyException ex)
{
ErrorInfo error = new ErrorInfo();
String response = null;
error.setErrorStatus(String.valueOf(HttpStatus.INTERNAL_SERVER_ERROR));
error.setErrorCode(String.valueOf(HttpStatus.INTERNAL_SERVER_ERROR)); // TODO Need to store Application specific error code
error.setErrorMessage("Communication Error : Unable to fetch conference data"); // TODO Need to get from message resource file
error.setDeveloperMessage(ex.getLocalizedMessage());
response = utilities.fromBeanToJson(error);
System.out.println("***Response : " + response);
return response; // Not able to receive this info
}
Actual Response :
<html><head><title>Apache Tomcat/6.0.29 - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 500 - Unable to fetch conference data</h1><HR size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u>Unable to fetch data</u></p><p><b>description</b> <u>The server encountered an internal error (Unable to fetch data) that prevented it from fulfilling this request.</u></p><HR size="1" noshade="noshade"><h3>Apache Tomcat/6.0.29</h3></body></html>
You need to remove the reason from #ResponseStatus.
This is needed because from the the Javadoc of #ResponseStatus we can see:
The reason to be used for the response. If this element is not set,
it will default to the standard status message for the status code.
Note that due to the use of {#code HttpServletResponse.sendError(int,
String)}, the response will be considered complete and should not be
written to any further.
I'm using spring integration to create TCP server and also to test if it works with junit. The problem is that i'm receiving an error: org.springframework.integration.ip.tcp.TcpOutboundGateway - Cannot correlate response - no pending reply. Please help me to fix it. Here is more info. I have unit test that send some data to server, server has to reply with "success" on each portion of data. but after second portion of read data, TcpOutboundGateway (on unit test side) write error to log.
So Server configuration file:
<int-ip:tcp-connection-factory id="crLfServer"
type="server"
port="5000"
single-use="false"
so-timeout="10000"
/>
<task:executor id="pool" pool-size="16"/>
<int-ip:tcp-inbound-gateway id="gatewayCrLf"
connection-factory="crLfServer"
request-channel="serverBytes2StringChannel"
error-channel="errorChannel"/>
<int:channel id="toSA" >
<int:dispatcher task-executor="pool" />
</int:channel>
<int:service-activator input-channel="toSA"
ref="connectionHandler"
method="handleData" />
<bean id="connectionHandler" class="com.pc.tracker.utils.ConnectionHandler" />
<bean id="objectMapper" class="org.codehaus.jackson.map.ObjectMapper"/>
<int:transformer id="serverBytes2String"
input-channel="serverBytes2StringChannel"
output-channel="toSA"
expression="new String(payload).trim()"/>
<int:transformer id="errorHandler"
input-channel="errorChannel"
expression="payload.failedMessage.payload + ':' + payload.cause.message"/>
Client configuration file:
<int:gateway id="gw"
service-interface="com.pc.tracker.tcp.ConnectionHandlerTestHellperGateway"
default-request-channel="input"/>
<int-ip:tcp-connection-factory id="client"
type="client"

and test that produce already mentioned error.

I've spent two days solving the problem.
sorry for long question.
Thanks.
You are sending data with embedded \r\n...

Remove them all; the framework will add one at the end.
Your server is sending multiple replies on the socket for one request. Search for connection id localhost:5000:51420:9f93417a-c879-4753-a61e-0b9485940d14. You will see that you sent your request at
2014-04-12 11:27:11,307
The reply is received at
2014-04-12 11:27:11,340
(onMessage() call) and sent to the reply channel at
2014-04-12 11:27:11,343
the next activity on that socket was the reception of another message
2014-04-12 11:27:11,346
for which there was nobody waiting hence the error message.
Now, looking at the connection id, we can see that the remote socket is 51420, so let's take a look on the server side...
The corresponding connection id on the server is localhost:51420:5000:66862ff3-3f40-4291-938f-0694bf3727be. The reply success to the original request was sent at
2014-04-12 11:27:11,339
However, that same thread reads another message (without another send) - notice the message Available to read:525.
So, the bottom line is you are using the default (de)serializer which expects the message to be terminated with \r\n but you are sending requests that have \r\n embedded in them so the server side is "seeing" multiple requests when the sender only sent one message.
TCP is a streaming protocol - you need to frame your data somehow so the server side knows when a message is complete. If you need to send data that contains \r\n you will need to use a different deserializer to detect the end of the data (perhaps the length header implementation, which is the most efficient).
The available standard serializers and information about customizing them are documented here.
I am trying to access a SOAP service which has the following charateristics:
1. WSDL is available without authentication
2. The service is accessible over https with basic_auth
3. According to the SOAP service, the "Authorization" header needs to be included in every request
Here is my code for construction the soap client:
#wsdl="https://example.com/table.do&WSDL"
#proxy="http://internal.proxy.com:8080"
#basic_auth=["user","pass"]
#headers={"Authorization" => "Basic"}
client = Savon.client do |globals|
globals.wsdl #wsdl
globals.proxy #proxy
globals.basic_auth #basic_auth
globals.headers #headers
end
Here is the client.globals.inspect:
#<Savon::GlobalOptions:0x0000000382c7a8 #options={:encoding=>"UTF-8",

when i call:
client.call(:get, message: { sys_id: "67d2f77ed9377840c53fc6da9c094635" })
The service is returning:

Am i constructing the client incorrectly? I don't see any authentication headers being sent on either the GET or PoST requests.
Do i need to add/remove anything to get this working? Your help would be appreciated.
I imagine you should be able to do the following:
client = Savon.client(endpoint: ENDPOINT, namespace: NAMESPACE, basic_auth: ["user", "password"])
(Or the same in block form).
Check this page under the "Authentication" heading: http://savonrb.com/version2/globals.html
(I am doing the same, but with a WSDL).
I work at Apple and we are working on the prototype using WSO2 ESB with Data Services Feature. I am using WSO2 ESB 4.0.3 with DSS feature. I have deployed data service and calling the data service from proxy service in ESB. I am using MAC OS X 10.7.4 and java version details are as below.
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04-415-11M3635)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01-415, mixed mode)
My DS service is expecting certain parameter say parameter A and I do not pass that this parameter in the Input XML I see following error on the WSO2 ESB console.

Looking at the SOAP fault I have to return the error message to client but even thought the correct error message must "Parameter Missing" SOAP fault's reason text is "javax.xml.stream.XMLStreamException"
Is there any thing wrong I am doing or is it BUG in DSS?
By looking at the stacktrace, I can see that you've enabled the SOAP tracer in invoking the service, disable the SOAP tracer and you should get the proper fault message.
Cheers,
Anjana.
As error message explains itself, it is expecting input parameters, which is not coming int the request. It can be fixed by two ways:
Passing empty tag from ESB without value.
Set default value in DSS.
First option works with all versions, here is the example for setting default value.
<payloadFactory media-type="xml">
<format>
<ds:DATA_SERVICE_REQUST xmlns:ds="http://ws.wso2.org/dataservice">
<ds:INPUT_PARAM_1>$1</ds:INPUT_PARAM_1>
</ds:DATA_SERVICE_REQUST>
</format>
<args>
<arg xmlns:ds="http://ws.wso2.org/dataservice" evaluator="xml" expression="get-property('INPUT_PARAMETER')"/>
</args>
</payloadFactory>
<call>
<endpoint>
<address uri="DSS_END_POINT"/>
</endpoint>
</call>
For 2nd option, please check your DSS version if this supports null values
Latest Version of DSS Supports default parameter values in the query param list.
Could you please give a try by adding defaultValue="#{NULL}" in query param list in your data service (dbs) file?
<query id="QUERY-ID" useConfig="DATA-SOURCE-ID">
<sql>-------------SQL QUERY HERE -----</sql>
<result ----------- >
<element ------------ />
</result>
<param defaultValue="#{NULL}" name="PARAM-NAME" ordinal="1" sqlType="INTEGER"/>
</query>
If this issue is still not resolved then it would be good if you can provide your API details.
