  1. POReflections returning Set with null elements
    text
    copied!<p>I'm using <a href="http://code.google.com/p/reflections/" rel="nofollow">Reflections</a> to find classes that have an specific annotation. My project structure is the following</p> <p>One WAR package: WEB-INF/classes/...packages.../ClassAnnoted1.class</p> <p>One JAR package that is included by the war that has a class that executes this code:</p> <pre><code>Reflections reflections= new Reflections(ClasspathHelper.forWebInfClasses(servletContext)) Set set= reflections.getTypesAnnotatedWith(CustomAnnotation.class) </code></pre> <p>CustomAnnotation is also present on the JAR package.</p> <p>the set size is correct (ie if I have 3 classes with the annotation in my WAR the jar, the set size comes back as 3), but all elements inside it are null instead of Class. I need to get the class and check the annotation parameters inside the class of the JAR.</p> <p>Anyone got any idea of why this is happening?</p> <p>EDIT:</p> <pre><code>Reflections reflections= new Reflections("com.my.customAnnotededClasses"); //package that my annoted class is in Set set= reflections.getTypesAnnotatedWith(CustomAnnotation.class); </code></pre> <p>Also does not work, in this case the set length is zero instead of the number of classes with the annotation.</p> <p>EDIT 2: Ok, the real problem was that I was packaging my whole application as an EAR so I had the following:</p> <pre><code>EAR ----&gt; WAR ----&gt; JAR </code></pre> <p>The jar was included in the EAR lib folder and not on the WAR lib folder. So the jar classes couldn't see the war classes, once i made the WAR depend on the JAR directly like this:</p> <pre><code>EAR ----&gt; WAR ---------&gt; JAR </code></pre> <p>It started working. But the original question still stands, there might be situations where I want the Jar classes included in the EAR instead of the WAR (if i have multiple wars that need to use my jar for instance).</p>
