wso2 esb json to json converting double quotes mis

Question

I have a problem in converting json to json in wso2 esb, actually I'm using payload factory in a proxy and I call the proxy with rest and json content. Here is my integration flow, I call a proxy and the proxy sends the request(with json content) to a jms message store then, I defined a message processor to consume messages from message store and send them to a defined endpoint(.net web api). but the problem is strings with numbers automatically get converted as integer elements: "orderId": 10000 ( I want it to be string "orderId": "10000") , but when I send the request directly from proxy to my end point (without using message broker) it works correctly. Could you please help me solve this problem?

For more details refer to my question with more details on this problem, and looks like this is a bug in wso2 esb 4.9.0 wso2 jira

Answer 2

For your problem need to change a JSON Message Formatters. please follow the below steps for that.

• change your working directory to [ESB Home]/repository/conf/axis2/axis2.xml

• then you need to change JSON Message Formatters instead of JsonStreamFormatter use org.apache.axis2.json.JSONMessageFormatter.

  <!--messageFormatter contentType="application/json"                                class="org.apache.synapse.commons.json.JsonStreamFormatter"/-->
    <messageFormatter contentType="application/json"
                              class="org.apache.axis2.json.JSONStreamFormatter"/>

You can use the following builder and formatter in axis2.xml

org.apache.synapse.commons.json.JsonStreamBuilder
org.apache.synapse.commons.json.JsonStreamFormatter

Remove existing builder and formatter for the "application/json" and add the below.

Add under Formaters section

<messageFormatter contentType="application/json"
                          class="org.apache.synapse.commons.json.JsonStreamFormatter"/>

Add under Builders section

 <messageBuilder contentType="application/json"
                            class="org.apache.synapse.commons.json.JsonStreamBuilder"/>
