In JRE1.4.2, the prompt does not have permission issues when the JavaScript call has been signed by JavaScript call.

In JRE1.4.2, if it is JavaScript to use the Applet method, even if the user has trusted the signature of this applet, there may be a problem that the permissions are not enough, but if the applet calls the method, there is no problem, for this, You can start a thread in the start method in the applet, this thread has sufficient permissions, then interacts in the JavaScript method, the following is the code public class myapplet extends applet {thread thread; string command; Object Result; Boolean isend = FALSE;

Public void start () {thread = new thread (new ruid run () {whele (! isend) {type {synchronized (thread) {thread.wait ();}} catch (exception e) {e .printStackTrace ();} if (isend) return; try {if ("callexe" .equals (command)) Result = callexe ();} catch (exception e) {E.PrintStackTrace ();} synchronized (cardapplet.this) ) {Cardapplet.this.notify ();}}}}; thread.start ();

Public void stop () {iesend = true; synchronized (thread) {thread.notify ();}}

String call () {this.command = "callexe"; try {synchronized (thread) {thread.notify ();} synchronized (this) {wait ();}} catch (exceptstacktrace (); } Return Result;} String CallexE () {// Todo Add Logic Here Return NULL;}
