  Hi!

  I don't seem get your point.  I understood that what should only be 
downloaded in the client/web browser are HTML, image ,text etc...but in 
our case I see class files being downloaded too in the client machine or 
work station which shouldn't be...How come this happens? I just wonder 
why...Any thoughts about this? The class files are stored in the 
C:\winnt\local settings\temporary internet files for WinNT4 and 
C:\documents and settings\...\local settings\temporary internet files 
for Win2K when you are running the app...

  Hi
  U know that when a browser do a request to the server, it send a html 
response to the browser, only there class going to the browser with 
applets.
  The user don=B4t have the class to decompiler it, only the own of the 
soft have the web aplications and the class.

    Hi!

    Hope anyone of you who are into servlet-based web development have 
noticed this problem. This is referring to the classes that are 
downloaded onto the local drive when running a web app in the client 
machine....Certainly, I would start thinking on the security issue on 
developing servlet- based web applications as everyone knows that there 
is such tool as decompiler to decompile class files into java files. 
This is pretty dangerous, don't you think? Have you guys anticipated 
this problem and already have solution to this one? I badly need your 
profund ideas or suggestions or any point of views for that matter...Is 
there something that we have to configure or to set up on the machine 
where the web server is running pertaining to security? or anything else 
missing?
    BTW, we're using tomcat 3.2.1

    
    Thanks in advance.
