Laurie.. are you sure this will work? Let us say i have a mapping that maps to a TelephoneAction in my strus-config.xml... the class name will get 'garbled' after obfuscation. When a hit is made, the struts runtime will look up the TelephoneAction class to forward the request and notices there is no class with that name anymore! Whether bytecode or sourcecode obfuscation, this problem will still persist!
One solution: Use the option *not* to obfuscate classnames of action classes. But are we done? Not yet... what if we use dispatch action class? By similar logic, you should leave even your method names unobfuscated! So that isnt too good... One of my friends suggested one ways to obfuscate the action class names and methods.As a part of obfuscation process generate a file containing mappings from old names to new names. Then based on this generated file, you can write a script to work on config.xml to find and replace the unobfuscated names with those from the mappings file generated. Some amount of work, but I guess it should work. The other approach is not to obfuscate action class names and method names in them. Just do flow obfuscation on these action classes. Action classes by design would not have too much "business code" in them .. as they would be delegated to some "business classes". Even if complex code (in terms of number of lines) does exist in them, flow obfuscation will make it difficult to read them. If they are fewer number of lines, then it may be easy to break flow obfuscation, but then in most cases the code would be so simple that it is OK that the hacker knows it ! ;-) Since rest of the classes (other than action classes) are obfuscated with out any constraints, you should be safe... at most your action classes would be "broken" into. May be .. you can treat your action classes like the DMZ (demilitarized zone). Dont know if some tools support all what has been written so far. If they do someone please let us know! :-) Regards, Raghu On 11/20/05, Laurie Harper <[EMAIL PROTECTED]> wrote: > > su mo wrote: > > Hi, > > > > I have STRUTS 1.2.7 based web application which I want to protect the > > decompilation of class files.
