It really does not look like a question about security. ;-) I am at a critical opportunity and I need to know answer to those questions because I Am defining my final project on this topic and I should check its feasibility before delivering my proposal So some one guide me on this please.   I have brought my old mail in the following   Hi every body, I am new to your group, and I have some questions about jvm and its security model. I want to intercept method calls or object creation in jvm and do call some os library before it, now I would like to Know if I can do this by JNI(java native interface). Yes, you can. One approach, writing your own/your customized class loader, call what ever you want by JNI if you want. Please refer to [1] for a sample. Indeed I have seen that jvm 1.6.1 distribution contains a “src” folder which includes source code for java API, But I don`t know whether it contains c++ source for jvm itself or not. Why not unzip and look into the "src'? You will find whatever inside. Any way I am going to have some manipulation on jvm security Welcome! but I don`t know where to start from. Security is a big concept, and covers many fields. Including sandbox, access control, authentication, etc. What's your interested tech? I would like you have to look at our guides[2], where describes the most of the aspect of java security.
