test1 and test2 contain two different implementations of the same+
−
classes. They are compiled and placed into two different target directories+
−
and two jar files test1.jar and test2.jar.+
−
+
−
The same class is in both jars/directories, but returns a different result+
−
from the TestClass.getValue() method. The test does the following+
−
+
−
1. copy test1.jar to a working directory and call it test.jar+
−
+
−
2. load class and invoke method (checking result)+
−
+
−
3. close the loader+
−
+
−
4. delete test.jar (check delete succeeds)+
−
+
−
5. copy test2.jar to same dir and repeat the test+
−
+
−
6. The two tests are then repeated by copying the directories+
−
   test1 and test2.+
−
+
−
The loader also includes a http:// URL in its search path and a http+
−
server is used to serve the required class.+
−
+
−
serverRoot is used as the root directory for the http server.+
