== Generating code with wsdl2java from Axis2 ==
== Overview ==
 
We use [https://cxf.apache.org/ Apache CXF] as framework to implement SOAP with Java.
 
Apache CXF comes with a tool called wsdl2java which reads the WSDL published by an OX App Suite installation and generates classes which represent corresponding SOAP objects and method calls.
 
So the general procedure is:
 
* Setup OX including the SOAP admin interface
* Create classes with wsdl2java
* Use these classes in your Java code to make SOAP calls
 
== Generating code with wsdl2java from Apache CXF ==

The script generates stubs for each of the Context, User, Group and Resource API within a separate subdirectory of the $CODEBASE directory.
== Example Code ==
Building the example code given below either requires some build tool / IDE of your choice (whose configuration is out of scope of this article) or you can build and run the example code manually like
# clean up old stuff from previous run
rm -rf codebase *.class
# generate java classes and compile them
./ox-wsdl2java
find codebase -name \*.java | xargs javac
# compile and run sample program
javac -cp codebase MyContextClientExample.java MyUserClientExample.java
java -cp .:codebase MyContextClientExample
java -cp .:codebase MyUserClientExample
Sample client code follows below.
MyContextClientExample.java shows createcontext, listcontext, deletecontext:

}
 
Finally sometimes it is required to not directly make a SOAP call, but to generate the request body separately. One example therefore are [[Gatling_Performance_Tests|gatling]] performance tests, where we can make SOAP tests if we just generate the SOAP (=HTTP POST) bodies separately and make, from the gatling point of view, simple HTTP POST requests.
 
Full working code therefore can be found in our gatling git repo, see [[Gatling_Performance_Tests|gatling]] for details. The relevant steps to create the SOAP body itself are given below. It is scala code; how to translate it to Java (if required) should be straightforward.
 
import admin.soap.context.{ CreateModuleAccessByName, CreateModuleAccessByNameResponse }
import com.openexchange.context.rmi.dataobjects.Credentials
import com.openexchange.context.soap.dataobjects.{Context, Database, User}
import java.io.{ByteArrayInputStream, ByteArrayOutputStream}

import javax.xml.parsers.DocumentBuilderFactory
import javax.xml.soap.{MessageFactory, SOAPMessage}
import org.w3c.dom.Document
val creds: Credentials = new Credentials
val ctx: Context = new Context
val oxadmin: User = new User
// fill relevant fields of the creds, ctx, oxadmin oxbjects
val cmab: CreateModuleAccessByName = new CreateModuleAccessByName
cmab.setAccessCombinationName("all")
cmab.setAdminUser(oxadmin)
cmab.setAuth(creds)
cmab.setCtx(ctx)
val jaxbContext: JAXBContext = JAXBContext.newInstance(classOf[CreateModuleAccessByName])
val jaxbMarshaller: Marshaller = jaxbContext.createMarshaller
jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, true)
val document: Document = DocumentBuilderFactory.newInstance.newDocumentBuilder.newDocument
jaxbMarshaller.marshal(cmab, document)
val soapMessage: SOAPMessage = MessageFactory.newInstance.createMessage
// optional cosmetic: change namespace from SOAP-ENV to soap to match other conventions
soapMessage.getSOAPPart().getEnvelope().removeNamespaceDeclaration("SOAP-ENV")
soapMessage.getSOAPPart().getEnvelope().addNamespaceDeclaration("soap", "http://www.w3.org/2001/12/soap-envelope")
soapMessage.getSOAPPart().getEnvelope().setPrefix("soap")
soapMessage.getSOAPHeader().setPrefix("soap")
soapMessage.getSOAPBody().setPrefix("soap")
// optional cosmetic end
soapMessage.getSOAPBody.addDocument(document)

How to provision Open-Xchange with Java and SOAP

Overview

We use Apache CXF as framework to implement SOAP with Java.

Apache CXF comes with a tool called wsdl2java which reads the WSDL published by an OX App Suite installation and generates classes which represent corresponding SOAP objects and method calls.

So the general procedure is:

  • Setup OX including the SOAP admin interface
  • Create classes with wsdl2java
  • Use these classes in your Java code to make SOAP calls

Generating code with wsdl2java from Apache CXF

See the sample script below on how to generate stubs for the Open-Xchange provisioning APIs.

#!/bin/bash

# 1. download apache-cxf tarball, extract it and "cd" into the directory
#    (this script has been developed and verified with CXF versions 3.0 and 3.1)
# 2. change variables CODEBASE, JAVA_HOME and WSDLURL
# 3. run this script "bash oxaas-wsdl2java"
export JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-amd64"
CODEBASE="./codebase"
WSDLURL="http://192.168.101.84/webservices"
CXF_HOME=/opt/apache-cxf-3.0.5

The script generates stubs for each of the Context, User, Group and Resource API within a separate subdirectory of the $CODEBASE directory.

        } catch (NoSuchContextExceptionException e) {
            e.printStackTrace();
        } catch (NoSuchUserExceptionException e) {
            e.printStackTrace();
        }
    }
}

Finally sometimes it is required to not directly make a SOAP call, but to generate the request body separately. One example therefore are gatling performance tests, where we can make SOAP tests if we just generate the SOAP (=HTTP POST) bodies separately and make, from the gatling point of view, simple HTTP POST requests.

Full working code therefore can be found in our gatling git repo, see gatling for details. The relevant steps to create the SOAP body itself are given below. It is scala code; how to translate it to Java (if required) should be straightforward.

val creds: Credentials = new Credentials
val ctx: Context = new Context
val oxadmin: User = new User
// fill relevant fields of the creds, ctx, oxadmin oxbjects

val cmab: CreateModuleAccessByName = new CreateModuleAccessByName
cmab.setAccessCombinationName("all")
cmab.setAdminUser(oxadmin)
cmab.setAuth(creds)
cmab.setCtx(ctx)

val jaxbContext: JAXBContext = JAXBContext.newInstance(classOf[CreateModuleAccessByName])
val jaxbMarshaller: Marshaller = jaxbContext.createMarshaller
jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, true)

val document: Document = DocumentBuilderFactory.newInstance.newDocumentBuilder.newDocument
jaxbMarshaller.marshal(cmab, document)

val soapMessage: SOAPMessage = MessageFactory.newInstance.createMessage

// optional cosmetic: change namespace from SOAP-ENV to soap to match other conventions
soapMessage.getSOAPPart().getEnvelope().removeNamespaceDeclaration("SOAP-ENV")
soapMessage.getSOAPPart().getEnvelope().addNamespaceDeclaration("soap", "http://www.w3.org/2001/12/soap-envelope")
soapMessage.getSOAPPart().getEnvelope().setPrefix("soap")
soapMessage.getSOAPHeader().setPrefix("soap")
soapMessage.getSOAPBody().setPrefix("soap")
// optional cosmetic end

soapMessage.getSOAPBody.addDocument(document)

val outputStream: ByteArrayOutputStream = new ByteArrayOutputStream();
soapMessage.writeTo(outputStream);
val soapBody: String = outputStream.toString()
