applet

问题 I have applet which loads form. The form has text, textarea, dropdown, checkbox controls. After upgrading to JRE 1.7 Im not able to right click inside my text fields to copy/paste any content. My JAR file is dually signed and security permissions set. I have also tried the workaround by changing settings in .java.policy file : // "standard" properies that can be read by anyone permission java.awt.AWTPermission "accessClipboard"; Interestingly enough I can do copy/paste by right click inside

问题 I have firefox 11 or the windows XP version of IE - and the browser has jre6 and I have a 6 month old jsdk but the browser doesn't use that for runtime. nice if log window had history and a scrollbar if there are a lot of prints.

问题 I have an applet that makes a SOAP request to a web service. It has no certificates or special security considerations, just a basic applet and webservice. After updating Java on a few computers to 1.6.0_26 I can say without a doubt that the update causes the following exception. (Previous versions of Java still work) com.sun.xml.internal.messaging.saaj.soap.MessageImpl saveChanges SEVERE: SAAJ0540: Error during saving a multipart message com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl:

String inputMessage; //message stored here BufferedReader in = new BufferedReader( new InputStreamReader(socket.getInputStream())); while((inputMessage = in.readLine()) != null){ //Update message buffer

I am thinking instead of implementing the file picker

问题 It is possible to access HTML DOM from an applet using netscape.javascript JSObject API. However, if I query a value of a input type="file", on some browsers (Opera) I get a full path to a selected file, but on other browsers (Firefox, Chrome) just a file name without path . Is it possible, having an HTML input type="file", to figure out the full path to the file selected in it from a Java applet? The reason why I bother: signed applets can access file system, and browsers' file selectors are
