From: ser@jersey.uoregon.edu To: java-interest@java.Eng.Sun.COM Date: Tue, 24 Oct 1995 16:35:52 -0700 -----BEGIN PGP SIGNED MESSAGE----- Content-Type: text/plain; charset=us-ascii Sami.Shaio@Eng.Sun.COM said: > You're exagerating the problem here.

You cannot call external code from an applet. > (Otherwise all the security would go out the window.) I am aware that DLLs are accessable from applications. I have also seen alpha applets which access DLLs which you are required to install yourself on your system. I am not certain that this functionality is available in the beta release. The need is to be able to access system-wide DLLs, like a common compression library such as zlib without having to rewrite the entire library in Java; the library is extant in the system, so there should ideally be no need for redundant installations of the code. However, if the ability exists in the beta incarnation of Java to access DLLs, even user-local ones, from applets then the situation is not as dismal as I proposed. We are still left, then, with the security issue: Java can have no control over the behavior of native code, and so to be secure, should not allow access to native code from applets. I am not neccessarily supporting this dogma, but it seems to be a major issue in the success of Java. - --- SER -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQB1AwUBMI14VLcbQtHnunGxAQFJFwMAhCBfN/9YdcYDYd55ic/QLosHzP4A9ghn TtDDrJydedFzbs0ozSd79fhVQH1AdijvkvkW6nLV9Ud8ySX+I2tJ/O2rOY060VIv z/Fh6YPOlzBuAvixgk34Rbg2xGTfwt+W =o+jj -----END PGP SIGNATURE----- - This message was sent to the java-interest mailing list Info: send 'help' to java-interest-request@java.sun.com
