Hello,

I made an SE which required class name as extension parameter.
 this class depend on SU using the SE, how to make to add to a my SU a jar containing my configured class?
thanks

Hi,

If you are using petals maven plugin to create your SU, you must add your jar as maven dependency. It will be added to the SU archive.
Then in your code you must create a class loader from the SU resources to be able to use it.

Hi,

If you want to load a class from a jar provided in your SU, you need to
create a classloader to embed the jar at deploiement time. Have a lool
to the POJO component, it's an fair simple illustration of this
mechanism.

If you are working with maven and the petals plugin, the java classes in
your maven project are automatically packaged into the SU artifact.

Hello,

I try this su descriptor :
<jbi:jbi version="1.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:jbi="http://java.sun.com/xml/ns/jbi"
        xmlns:extensions="http://petals.ow2.org/extensions"
        xmlns:petalsCDK="http://petals.ow2.org/components/extensions/version-4.0"
        xmlns:hello="http://petals.ow2.org/Hello"
        xmlns:calculator="http://petals.ow2.org/Calculator"
        xmlns:soap="http://petals.ow2.org/components/soap/version-3.1">
        <jbi:services binding-component="false">
               
                <jbi:provides interface-name="hello:helloInterface"
                        service-name="hello:helloService" endpoint-name="helloEndpoint" >
                        <petalsCDK:wsdl xsi:nil="true"/>
                        <hello:se.sca.interface>personne.Calculator</hello:se.sca.interface>
                </jbi:provides>
                <jbi:consumes
                        interface-name="calculator:ejbCalculatorInterface"
                        service-name="calculator:ejbCalculatorService"
                        endpoint-name="ejbcalculatorEndpoint">
                        <petalsCDK:mep>InOut</petalsCDK:mep>
                </jbi:consumes>
        </jbi:services>
</jbi:jbi>

and this SU content :
+META-INF
    - jbi.xml
    - my_classes.jar  ( included  the class  personne.Calculator)


In the my Class JBIListener the code is like this :
public static final string SERVICE_INTERFACE = "se.sca.interface";
...

                String nomClassInterface = this.getExtensions().get(SERVICE_INTERFACE);
               
                ClassLoader cl = this.getClass().getClassLoader();
                Class classInterface = cl.loadClass(nomClassInterface);


but if have a ClassNotFoundException : personne.Calculator when a JBI message is processing.

you must create a classloader with embed your jar.
there is an utility class in ClassLoaderUtil in the CDK to do that
easily.

ok it's good, i changed my code like this :

String suRootPath = this.getInstallRoot();
String nomClassInterface = this.getExtensions().get(SERVICE_INTERFACE);
ClassLoader cl = ClassLoaderUtil.createClassLoader(suRootPath, this.getClass().getClassLoader());

thanks
