Spring Context on BPEL Process

653103Jul 21 2011 — edited Jul 25 2011
I'm trying to execute a method of a class as a service using the Spring Context Component.

When the process gets to that activity thrwos an exception, I thought it was ´cause the method parameter types so I created a new class very simple... this is the class.
package mx.gob.lotenal.sasle.test;

public class Class1 {
    public Class1() {
        super();
    }
    
    public String testSpringContext(String in){
      return in + " Another String";    
    }
}
the Spring Configuration is this: 
<?xml version="1.0" encoding="windows-1252" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:jee="http://www.springframework.org/schema/jee"
       xmlns:lang="http://www.springframework.org/schema/lang"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:sca="http://xmlns.oracle.com/weblogic/weblogic-sca"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/tool http://www.springframework.org/schema/tool/spring-tool-2.5.xsd http://xmlns.oracle.com/weblogic/weblogic-sca META-INF/weblogic-sca.xsd">
  <!--Spring Bean definitions go here-->
  <sca:service name="TestService" target="TestService" type="mx.gob.lotenal.sasle.test.Class1"/>
      <bean id="TestService" class="mx.gob.lotenal.sasle.test.Class1"></bean> 
</beans>
and this is the exception thrown on the execution:

When the activity takes place it doesn't end, Enterprise Manager Console says there are X instances of this component running, even older instances are running...

What is missing on my configuration?

Thanks in advance

I am going to answer myself!, :P

I did NOT create a java Interface for both classes, don't know Why this is really necessary but it is.

The best reference i found is this [http://redstack.wordpress.com/2011/04/05/using-javaspring-components-in-soabpm-11g/|http://redstack.wordpress.com/2011/04/05/using-javaspring-components-in-soabpm-11g/]

please file a bug on this - an NPE in this code area is certainly a bug. This should not deploy as the code expects an interface in the <service> tag, that subsequently gets implemented in the bean class.
