Modified: jasper/src/share/org/apache/jasper/runtime
JspRuntimeLibrary.java
Log:
- Implemented Java SecurityManager
- Switched to using URLClassLoader
Jasper now creates a URLClassLoader for each JSP page and defers any other
class loading to the web app context class loader. Using a single class
loader per JSP allowed me to remove all the code that increments the
class version number, i.e. the work directory no longer has multiple
*.java and *.class files for the same JSP page. These changes also made
it easy for me to put the java source and class files in the same directory
tree as found in the web app context. When Jasper is run in a servlet
container it no longer puts the class files in a package, they are now
in the default package.
