How to load custom .xml file from WEB-INF?

sijalica Sep 2, 2012 10:49 AM

Ok, I've been reading threads for an hour and I can't find a solution to my problem.

The thing is that I use JBoss AS 7.1 and deploying WAR application to JBoss. I made a custom mapping.xml file that Dozer needs but I cannot locate file inside my war. What I've tried so far is:

System.out.println(this.getClass().getClassLoader().getResource("/WEB-INF/mapping.xml"));
  System.out.println(this.getClass().getClassLoader().getResource("/mapping.xml"));
  System.out.println(this.getClass().getClassLoader().getResource("/resources/mapping.xml"));
  System.out.println(Thread.currentThread().getContextClassLoader().getResource("/resources/mapping.xml"));
  System.out.println(Thread.currentThread().getContextClassLoader().getResource("/mapping.xml"));
  System.out.println(Thread.currentThread().getContextClassLoader().getResource("mapping.xml"));
  System.out.println(Thread.currentThread().getContextClassLoader().getResource("/WEB-INF/mapping.xml"));
  System.out.println(this.getClass().getClassLoader().getResource("WEB-INF/mapping.xml"));
  System.out.println(this.getClass().getClassLoader().getResource("webapp/WEB-INF/mapping.xml"));
  System.out.println(this.getClass().getClassLoader().getResource("/webapp/WEB-INF/mapping.xml"));

and all of them return null. What is left to try?

Also tried /target/classes/WEB-INF/mapping.xml and all combinations like /target/... taget/... /classes/... classes/... etc...

You need to use javax.servlet.ServletContext#getResourceAsStream(java.lang.String).

Otherwise, if you must use a classloader, then your resource must be somewhere in WEB-INF/classes.

I cannot access ServletContext from this class:

public class MyModelMapper {

          private static class SingletonHolder {
                    private static Mapper INSTANCE= new DozerBeanMapper() {
                              {
                                        List<String> mappingFileUrls= new ArrayList<String>();
//                                        InputStream resourceAsStream = this.getClass().getResourceAsStream("/WEB-INF/mapping.xml");
//                                        InputStream resourceAsStream2 = this.getClass().getResourceAsStream("WEB-INF/mapping.xml");
//                                        InputStream resourceAsStream3 = this.getClass().getResourceAsStream("mapping.xml");
//                                        InputStream resourceAsStream4 = this.getClass().getResourceAsStream("/mapping.xml");
//                                        System.out.println(this.getClass().getClassLoader().getResource("/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("classes/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("core/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("/core/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println("a:"+ this.getClass().getClassLoader().getResource("/resources/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/resources/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("core/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/core/target/classes/WEB-INF/mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("mapping.xml"));
//                                        System.out.println(Thread.currentThread().getContextClassLoader().getResource("/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("webapp/WEB-INF/mapping.xml"));
//                                        System.out.println(this.getClass().getClassLoader().getResource("/webapp/WEB-INF/mapping.xml"));
//                                        mappingFileUrls.add(this.getClass().getClassLoader().getResource("/WEB-INF/mapping.xml").getFile());
//                                        setMappingFiles(mappingFileUrls);
                              }
                    };
          }
  

          public static <D> D map(Object source, Class<D> destinationType) {
                    SingletonHolder.INSTANCE.map(source, destinationType);
          }
}

And if I turn this MyModelMapper to @ApplicationScoped bean, how would I access ServletContext? Via CDI? I tried and I get "null" value when I debug the class...?

Tried a ServletContextListener.contextInitalized(SCE e) and stash the context away?

Well, I solved it the following way:
I put the file to:
src/main/resources/mapping.xml
instead of webapp/WEB-INF

and loaded it only by providing "mapping.
