insert node to empty SOAP message

Submitted by heng005.hotmail.com on August 1, 2010 - 08:35

i want to insert a element called result into an empty SOAP message. so i create a XSLT transform but i'm very new to XSLT. input SOAP: <?xml version='1.0' encoding='utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Body /> </soapenv:Envelope> expected output: <?xml version='1.0' encoding='utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Body> <result>aaa</result> </soapenv:Body> </soapenv:Envelope> my xslt is: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <result>aaaa</result> </xsl:template> </xsl:stylesheet> my XSLT transform is: <xslt key="addResultXSLT" /> i don't config the Source attribute. i found an error like this: ERROR XSLTMediator Unable to perform XSLT transformation using : addResultXSLT against source XPath : s11:Body/child::*[position()=1] | s12:Body/child::*[position()=1] java.lang.NullPointerException at org.apache.synapse.util.jaxp.StreamSourceBuilder.getSource(StreamSourceBuilder.java:56) Can you suggest what is wrong? what is the best way to insert a node to SOAP message, XSLT? Which part of an empty SOAP message is selected, if i don't config the source attribute of XSLT mediator? Thank you in advance

i used my XSLT to transform the CheckPriceRequest (sample 8) and it work properly. i got the expected output: <?xml version='1.0' encoding='utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"> <wsa:To>http://localhost:9000/services/SimpleStockQuoteService</wsa:To> <wsa:MessageID>urn:uuid:C23AF1E9E2A3A2AD5F1280713663949</wsa:MessageID> <wsa:Action>urn:getQuote</wsa:Action> </soapenv:Header> <soapenv:Body> <result>aaaa</result> </soapenv:Body> </soapenv:Envelope> Does my problem occur because of an empty SOAP Body? and what should the xsl file be?

how to use enrich mediator

Submitted by heng005.hotmail.com on August 2, 2010 - 00:29.

after i've read all of manual page of enrich mediator. https://10.99.0.227:9443/carbon/enrich-mediator/docs/userguide.html http://wso2.org/project/esb/java/3.0.0/docs/mediators/enrich.html i still don't know how to use it. can you please give me a short example. how to set the enrich mediator if i want to add a part of xml (foo) into an empty SOAP body. i think the WSO2 3.0.0 interface cannot handle all of the enrich mediator's options, such as inline text or property. Thank you. heng

Hi! I am also interested in

Hi! I am also interested in enrich mediator. I was not able to find any samples except configuration doc. I am trying to do the following: 1) Assume we have the following soap request: <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"> <soapenv:Body> <ns1:fireEvent xmlns:ns1="http://test.com"> <ns1:message>HI THERE</ns1:message> </ns1:fireEvent> </soapenv:Body> </soapenv:Envelope> And i have a string property in message context called 'myMessage' : <test>HI</test> How insert myMessage string as xml to message tag using enrich mediator? The result should be: <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"> <soapenv:Body> <ns1:fireEvent xmlns:ns1="http://test.com"> <ns1:message><test>HI</test></ns1:message> </ns1:fireEvent> </soapenv:Body> </soapenv:Envelope> 2) The same as 1 but 'myMessage' should be set as text content: <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"> <soapenv:Body> <ns1:fireEvent xmlns:ns1="http://test.com"> <ns1:message><test>HI</test></ns1:message> </ns1:fireEvent> </soapenv:Body> </soapenv:Envelope> 3) Is it possible to insert text content from registry to tag(the same way as 1 and 2)? Thx for help!

I have looked at sources of EnrichMediator. 1) In my case to achieve this i need at first to convert string to OMElement. I have choosed to use JS Mediator: <script language="js"><![CDATA[ var content= mc.getProperty('myContent'); var contentElement= Packages.org.apache.axiom.om.impl.llom.util.AXIOMUtil.stringToOM(content); mc.setProperty('myContent',contentElement); ]]></script> <enrich xmlns="http://ws.apache.org/ns/synapse"> <source clone="true" type="property" property="myContent"/> <target action="child" type="custom" xpath="$body/ns1:fireEvent/ns1:message" xmlns:ns1="http://test.com"/> </enrich> 2) Not possible via enrich mediator. Need to manipulate with nodes in JS mediator using AxiomXPath as described at http://wso2.org/library/265 3) I have not found how to set registry string content to property. One of the solution is to use getEntryDefinition in JS mediator and convert InputStream to String by hand. If i do smth wrong,please correct me. Thx.

are there any plans to improve the enrich mediator, so that it can solve the second scenario pointed by werdex? (insert text content into a given message tag) Another problem is that the Enrich Mediator only works with single notes. for example if you have: <coordinates> <x>1</x> <x>1.1</x> <y>0.9</y> <y>0.99</y> <z>0</z> <z>1</z> </coordinates> you can't take all x, y and z's with the XPath 'coordinates/*' and copy them into an other message. it would be really nice to have because It seems that 75% of my enrich cases need such functionality...

Please create a JIRA. We have done some improvements to the enrich mediator in the current trunk, will consider the issue pointed out for the next release ~ Indika
