I installed weblogic 4.5 im my office computer. I can run the jsp files 
which do not use Java classes. But when I run Screen1.html, Screen2.html, 
... exceptions are thrown. There are not instructions in Prof_jsp book.
    I download the source code of Prof_jsp, expended it in chapters, and 
put them in public_html folder. I also put the Java class in 
weblogic/classes/. I recompiled those java class with JBuilder3.5 using 
JDK1.1.7B.
Could you please tell me how to run those files? 

Thank you
