When I tried to invoke a JSP, javac says that the root cause is "java.lang.NoClassDefFoundError: sun/tools/javac/Main". Is that the tool.jar? How can I fix this?

There can be several reason for that
1)set the classpath till web-inf/classes
2)class file not available in classes directory
3)tool.jar not available in classpath

make the classpath variable include the file JAVA_HOME\lib\tools.jar
This should solve the problem

Some application servers (such as Orion) require you to copy tools.jar into the application server lib or root directory.
