I'm not completly sure on this, but even if they were decompiled (which is illegal to do if the source is copyrighted), you would still need to find a flaw of some sort to hack it. You can't actually change the code of the applet using a dissassembler. If you write clean code you will be just fine.

Decompiler can only generate the source. He/she can get the source of the applets, but cannot upload the new hacked applet to your server (unless he/she has access to your server

yes, i know that they can't actally put it on the sever, but sometimes (if you use MySQL) can get the pass word and mess with the tables. if they do this, the whole program won't work or even senitive infomation can be put in the public. so is there a way to make it so that the password is encrypted and the tables are safe?

I don't have strong knowledge about java, but to hack an applet is not an easy task, firstly they need to download the applet, and later they need decompile it right they decompiled, BUT for they know the password they need to hack a database (really I don't know what kind of applet that you're talking about). The problem for hackers or crackers it's? "how do I hack the database?" there enters the cryptografy process. What that I mean it's -> an applet it's an application that you loads from you PC, and the passwords or another data will be passed through a network process.

But I believe, that's your problem it's. You're building a website in java, right?! so you wanna make applets, and you wanna put applets for peoples make an download and the problem it's something about a security.
I'm right?! if the problem is it. I have a suggestion on your application, or applet, it's interisting on you applet code you don't put your code, soon at interface to difficult the hackers action, you should the interface and when you or the applet user submit something, so you on put an referred link, and that refer to the database, on database you use some criptografy algoritm. it's my tip it's not the best secure system but I believe thats works.

Ps: I hope that it helped you.

Maybe you could try including a file with your user name and passwords in it for mysql, and then put the permissions on it so that only the server can read it. This is more secure than having it in the applet itself. Its what I do with all my PHP coding.
