Bonita BPM 6.x: Consume soap call and use element content for gateway

Q&A
1

Hello everyone,

I’m new to BonitaBPM. I designed an easy process with only a service task (with a web service SOAP connector) and a gateway. The application successfully receives the web service call from Bonita. The application tells me that a response has been sent back to Bonita. The problem is that I have no idea how to consume the soap message. I only want to use the content of one element in order to make the decision at the gateway.
I found the response configuration (where I check the ‘Returns envelope’ or ‘Returns body’ checkbox) and the output operation. I don’t know what kind of Groovy script I have to use.

Can someone please help me?

Thanks in advance!

Maybe you want to retrieve the webservice return value.

That code worked for me (bonita v 6.2.2)

Put that code in a groovy expression and save it into a variable.

import javax.xml.transform.dom.DOMResult;
import javax.xml.transform.Source;
import javax.xml.transform.TransformerFactory;
import org.w3c.dom.Document; Source source = sourceResponse;
DOMResult result = new DOMResult(); TransformerFactory.newInstance().newTransformer().transform(source, result);
return result.getNode().getChildNodes().item(0).getTextContent();

With that code you can get the whole soap envelope, then you can parse and get the value you want to retrieve in a string and cast to the desired type.

import javax.xml.transform.;
import javax.xml.transform.dom.;
import javax.xml.transform.stream.*;
import org.w3c.dom.Document;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.sax.SAXSource;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMResult;
try{
StringWriter sw = new StringWriter();
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer(); transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, “yes”); transformer.setOutputProperty(OutputKeys.METHOD, “xml”); transformer.setOutputProperty(OutputKeys.INDENT, “yes”); transformer.setOutputProperty(OutputKeys.ENCODING, “UTF-8”); transformer.transform((SAXSource) sourceResponse, new StreamResult(sw));
String result = sw.toString();
if(result!=null && !result.isEmpty())
{
return sw.toString();
}
}
catch(Exception e)
{
return e.toString()
}

Thanks for your response. What kind of variable should I use? Just a java.util.string? And how can I get the content from a specific element (for example: rep:status)?

Hi,

Thanks for all your help! Now I get at least something back (it isn’t what I’ve expected though). I get a :

javax.xml.transform.TransformException: java.lang.NullPointerException

When I test my wsdl with SOAPUI (and mule up and running), then I’m receiving a correct soap response.

Do you think this is an issue in my Bonita flow conf or in my Mule project (where I expose my webservice from).

Once again, thanks for your help. You can also mail me directly I’ve that is easier for you :slight_smile: (it’s romariolodder@gmail.com).
