Some Background Knowledge About the Java Class Loaders
When the JVM is started, three class loaders are used:
- Bootstrap class loader
- Extensions class loader
- System class loader
The bootstrap class loader loads the core Java libraries located in the <JAVA_HOME>/jre/lib directory. This class loader, which is part of the core JVM, is written in native code.
The extensions class loader loads the code in the extensions directories (<JAVA_HOME>/jre/lib/ext, or any other directory specified by the java.ext.dirs system property). It is implemented by the sun.misc.Launcher$ExtClassLoader class.
The system class loader loads code found on java.class.path, which maps to the CLASSPATH environment variable. This is implemented by the sun.misc.Launcher$AppClassLoader class.
The Weblogic Server and Application Configuration
This is weblogic 10.3.2. The application is deployed to the myAppwls10loc domain. There is a startup class for the domain. The domain lib directory has a jar jt400.jar.In the command startWeblogic.cmd, two additional jars are put onto the classpath:
set CLASSPATH=C:\workshop\myclient.jar; %MAVEN_HOME%\oracle\jars\aqapi-9.0.2.jar ;%CLASSPATH%
The application is an ear. It has two modules: a war and an ejb jar. The ear has the following layout:
APP-INF
classes
lib
x.jar
META-INF
myejb.jar
mywar.war
In summary, the results are the following.
- The classes in myclient.jar ( used by the startup class ) are loaded with the following hierarchy:
| sun.misc.Launcher$ExtClassLoader@19134f4 | sun.misc.Launcher$AppClassLoader@47858e
The classes in APP-INF/lib/x.jar and the classes in myejb.jar are loaded with the following hirearchy (NOTE: their context class loaders are different though):
| sun.misc.Launcher$ExtClassLoader@19134f4 | sun.misc.Launcher$AppClassLoader@47858e | java.net.URLClassLoader@164dbd5 | weblogic.utils.classloaders.GenericClassLoader@1db6942 | weblogic.utils.classloaders.FilteringClassLoader@11f9cee | weblogic.utils.classloaders.GenericClassLoader@f8d6a6
Add the code to print the class loader hierarchy in the jsp file in mywar.war. The output is the following:
| sun.misc.Launcher$ExtClassLoader@19134f4 | sun.misc.Launcher$AppClassLoader@47858e | java.net.URLClassLoader@164dbd5 | weblogic.utils.classloaders.GenericClassLoader@1db6942 | weblogic.utils.classloaders.FilteringClassLoader@11f9cee | weblogic.utils.classloaders.GenericClassLoader@f8d6a6 | weblogic.utils.classloaders.ChangeAwareClassLoader@17b51e8 | weblogic.servlet.jsp.TagFileClassLoader@18d70a6 | weblogic.servlet.jsp.JspClassLoader@a3af1c
You can see that this is a child class loader of the class loader that loads the classes in myejb.jar and x.jar.
Below are more details. In the following log file, the class SampleBo is in a jar that resides in the directory APP-INF/lib directory. And the class XyzMessageHandlerImpl is in myejb.jar.
The following functions are used to print out the classloader tree:
private void printClassloaders(Class clazz) {
ClassLoader classLoader = clazz.getClassLoader();
System.out.println("==============================");
System.out.println("Class name:" + clazz.getName());
printCLtree(classLoader, "");
System.out
.println("Thread.currentThread().getClass().getClassLoader():");
ClassLoader cl = Thread.currentThread().getClass().getClassLoader();
printCLtree(cl, "");
System.out.println("==============================");
}
private void printCLtree(ClassLoader cl, String indent) {
if (cl == null) {
return;
}
System.out.println(indent + "ClassLoader=" + cl);
ClassLoader pcl = cl.getParent();
if (pcl == null) {
System.out.println(indent + " ClassLoader=" + pcl);
} else {
printCLtree(pcl, indent + " ");
}
}
public static void printClassLoaderHierarchy(Class c) {
ClassLoader cl = c.getClassLoader();
System.out.println("___________________START_______________________");
System.out.println("\nClass loader tree");
printClassLoaderTree(cl);
System.out.println("\nContext loader tree");
ClassLoader l = Thread.currentThread().getContextClassLoader();
printClassLoaderTree(l);
System.out.println("____________________END_______________________");
}
public static void printClassLoaderTree(ClassLoader l) {
ClassLoader p = l.getParent();
if (p != null)
printClassLoaderTree(p);
String u = "";
if (l instanceof URLClassLoader)
u = getURLs(((URLClassLoader) l).getURLs());
System.out.println((new StringBuilder("\t|\n")).append(l).append(" ")
.append(u).toString());
}
public static String getURLs(URL urls[]) {
if (urls == null)
return "{}";
StringBuffer b = new StringBuffer("{");
for (int i = 0; i < urls.length; i++)
b.append(urls[i]).append(":");
b.append("}");
return b.toString();
}

Class loaders for the class in APP-INF/lib and myejb.jar
In another test, I found the class loader that loads the class in the EJB module is the same as the one that loads the classes in the jars in the APP-INF/lib directory. In this test, there is no jar in the lib directory of the domain:C:/bea1032/user_projects/domains/myAppwls10loc/libThe following is the log for the class in APP-INF/lib:
