Doesn't seem like anything has happened here. I've ended up referencing each
indiviudal entity-class, though it's a little more work.
However if you have lot's of entity beans, and you need an efficient way to
find them and create the xml-references for persitence.xml - try this little
piece of code:
| import java.io.File;
| import java.lang.annotation.Annotation;
|
| /**
| * Tool to scan for all entity beans in a package and generate
persistence.xml class entries
| * @author peter
| *
| */
| public class GenPersistArchives {
| String basePath;
| String persistClasses = "";
|
| public GenPersistArchives(String basePath)
| {
| this.basePath = basePath;
| File dir = new File(ClassLoader.getSystemResource(basePath).getPath());
| scan(dir);
| System.out.println(persistClasses);
| }
|
| static final String translateToJavaPath(String uri)
| {
| // Translate into classname, and also handle subclasses
| String className = uri.replace(".class","");
| if(className.indexOf("$1")>0)
| className = className.substring(0,className.indexOf("$1"));
| className = className.replace("/",".");
| return className;
| }
| private void scan(File dir)
| {
| for(File file : dir.listFiles())
| {
| if(file.isDirectory())
| scan(file);
| else
| {
| String relativePath = file.getPath();
| relativePath = relativePath.substring(relativePath.indexOf(basePath));
| String className = translateToJavaPath(relativePath);
| try
| {
| Class cls = Class.forName(className);
| for(Annotation ann : cls.getAnnotations())
| {
|
if(ann.annotationType().getName().equals(javax.persistence.Entity.class.getName()))
| {
| persistClasses+="<class>"+className+"</class>\n";
| }
| }
|
| } catch(Exception e)
| {
| e.printStackTrace();
| }
|
| }
| }
| }
| /**
| * @param args
| */
| public static void main(String[] args) {
| // Package to scan
| new GenPersistArchives("com/lightminds/cms/ejb3");
|
| }
| }
|
Good luck,
Peter
