<div class="jive-rendered-content"><p>Alright, made some progress. When specifying after and before filters it seems to have effect, however I've found one issue when trying to setup a configuration simulating default classloading behavior for ear deployments.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For ear deployments default is parent-first="false" ie. parent-policy "AFTER_BUT_JAVA_BEFORE".</p><p>When setting up jboss-classloading-domain.xml this changes to parent-first="true" ie. parent-policy "BEFORE"</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So what I tried was to modify jboss-classloading.xml to simulate the default behavior based on ParentPolicy class:</p><p>/** Java and Javax classes before, everything else after */<br/>   public static final ParentPolicy AFTER_BUT_JAVA_BEFORE = new ParentPolicy(ClassFilterUtils.JAVA_ONLY, ClassFilterUtils.EVERYTHING, "AFTER_BUT_JAVA_BEFORE");</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>To start from the beginning, I've setup:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><?xml version="1.0" encoding="UTF-8"?><br/><classloading-domain xmlns="urn:jboss:classloading-domain:1.0" name="jboss.j2ee:extension=LoaderRepository,service=EARDeployment,url=&apos;myapp.ear&apos;" parent-domain="DefaultDomain"><br/> <parent-policy><br/>  <before-filter><br/>   <javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.JavaOnlyClassFilter" /><br/>  </before-filter><br/>  <after-filter><br/>   <javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.EverythingClassFilter" /><br/>  </after-filter><br/> </parent-policy><br/></classloading-domain></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>However both JavaOnlyClassFilter and EverythingClassFilter have private constructor so I'm getting:</p><p>java.lang.RuntimeException: Error constructing javabean</p><p>Caused by: java.lang.IllegalAccessException: Class org.jboss.reflect.plugins.introspection.ReflectionUtils can not access a member of class org.jboss.classloader.plugins.filter.JavaOnlyClassFilter with modifiers "private"</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>And by the way - specifying multiple beans within one filter will work?</p><p>like for example:</p><p><before-filter><br/>   <javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.JavaOnlyClassFilter" /><br/>   <javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.NegatingClassFilter"><br/>    <constructor><br/>     <parameter><br/>      <javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.spi.filter.RecursivePackageClassFilter"><br/>       <constructor><br/>        <parameter>org.hibernate</parameter><br/>       </constructor><br/>      </javabean><br/>     </parameter><br/>    </constructor><br/>   </javabean><br/>  </before-filter></p></div>
