Injecting file in mule using getResourceAsStream

Question

I'm using Mule 3.4. I kept a xml file in /src/main/resource/request and using initialize method and resource as stream, tried to load file from classpath and getting Null Pointer Exception

My configuration as follows spring.xml

    <bean id="initSoapFault" class="org.hhmi.transformer.SOAPResponseTransformer" init-method="initialize" />

My Flow is following

    <spring:beans>
     <spring:import resource="classpath:conf/spring.xml"/>
     </spring:beans>

My transformer class is code snippet is following

    public void initialize() throws IOException {
     try {
       inputStream =Thread.currentThread().getContextClassLoader().getResourceAsStream("classpath:request/soapFault.xml");
       docXmlResponse = IOUtils.toString(inputStream);
        } finally {
       IOUtils.closeQuietly(inputStream);
        }       }

Answer 1

The problem is most likely that you use the " classpath: " prefix when invoking getResourceAsStream() . That prefix should only be used in conjunction with a Spring ResourceLoader , but not with a standard Java classloader .

Answer 2

IT's working. I'm putting code snippet, it may help others

to get bean in transformer. I use following

      private volatile ClassPathXmlApplicationContext context;

     public SOAPResponseTransformer()  {
      context = new ClassPathXmlApplicationContext(getConfigResources());
     }

 protected String getConfigResources()
{
    return "conf/spring.xml";
}

Then call where ever you need bean

  ResourceInjection injection =  (ResourceInjection) context.getBean("initSoapFault");

  injection.getter Method
