Mule - wrap http parameters with a fixed soap request - http

Question

What transformer should I use to extract parameters from an http message like http://localhost:8088/?id=xxx&type=yyyy ans put the values of the id and the type parameters into a fixed soap request like :
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsd="http://wsdouane/">
<soapenv:Header/>
<soapenv:Body>
<wsd:find>
<entity>
<id>xxxx</id>
<type>yyyy</type>
</entity>
</wsd:find>
</soapenv:Body>
</soapenv:Envelope>
Http output
Cannot bind to address "http://127.0.0.1:8088/" No component registered on that endpoint
File output
<?xml version='1.0' encoding='UTF-8'?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:findResponse xmlns:ns2="http://wsdouane/"/>
</S:Body>
</S:Envelope>
in order to pass to a JAX-WS web service?
thank you

Answer 1

The process of retrieving query params and setting them in an object and then into a SOAP object, is not a single step process with a single transformer.
Step 1: You can use
<http-request-to-parameter-map>
transformer to get the query params as a Map.
Step 2: Then use this map to create a object with the map vlaues.
Step 3: And then send the object to your JAX-WS client component.
More reference of the transformers and the http and servlet module references can be found at below links.

Updated answer to use XSLT and proxy client.
<flow name="SOAPWebService" >
<http:inbound-endpoint address="http://localhost:8088/" exchange-pattern="request-response">
</http:inbound-endpoint>
<set-variable value="#[message.inboundProperties['id']]" variableName="paramId"></set-variable>
<set-variable value="#[message.inboundProperties['type']]" variableName="paramType"></set-variable>
<component class="com.example.components.SampleComponent" ></component>
<mule-xml:xslt-transformer
maxIdleTransformers="2" maxActiveTransformers="5"
xsl-file="C:\WorkSpace\MyProject\src\main\resources\xslt\PrepareRequestXML.xsl">
<mule-xml:context-property key="paramId"
value="#[flowVars['paramId']]" />
<mule-xml:context-property key="paramType"
value="#[flowVars['paramType']]" />
</mule-xml:xslt-transformer>
<cxf:proxy-client payload="body"
enableMuleSoapHeaders="true">
</cxf:proxy-client>
<http:outbound-endpoint exchange-pattern="request-response"
address="http://localhost:8080/ClientsDB/douane" doc:name="HTTP">
</http:outbound-endpoint>
<byte-array-to-string-transformer doc:name="Byte Array to String" />
<file:outbound-endpoint ....... .. />
</flow>
Below is the correct XSLT
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns="http://wsdouane/">
<xsl:output method="xml" indent="yes" />
<xsl:param name="paramType"></xsl:param>
<xsl:param name="paramId"></xsl:param>
<xsl:template match="*" >
<xsl:element name="find" namespace="http://wsdouane/">
<xsl:element name="entity">
<xsl:element name="id">
<xsl:value-of select="$paramType"/>
</xsl:element>
<xsl:element name="type">
<xsl:value-of select="$paramId"/>
</xsl:element>
</xsl:element>
</xsl:element>
</xsl:template>
<xsl:template match="text()|processing-instruction()|comment()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The code for SampleComponent class is
package com.example.components;
import org.mule.api.MuleEventContext;
import org.mule.api.lifecycle.Callable;
public class SampleComponent implements Callable {
#Override
public Object onCall(MuleEventContext eventContext) throws Exception {
String str = "<sample> </sample>";
return str;
}
}
