next-generation-plugin

问题 I have a problem starting a commercial JavaWS application on IE11 on some computers at work. The application eventually starts but the user has to try several times before it works whick is very annoying. We are currently using JRE 1.8.0_40 on Windows 7. I have tried all possible things and in my research I've seen some references to Java Next-Generation Plugin and that It should be activated. When I open the Java Configuration I can't find this option. Why is that? I have been reading this

问题 I have generated the keystore and its inner key. Then I have my signed java applet. But each time I start my jnlp applet I can see the Internet browser security Warning dialog. When the application server and the client machine are in the same network , in the dialog box shows "Publisher: MyCompanyName "but when we access the application form the internet,it shows that "Publisher: UNKNOWN". Anyone could let me know what the cause of this problem.Any help would be greatly appreciated. 回答1:

问题 I am trying to add libraries to applet. I am using the jnlp + deploy java javascript. Everything seems to be configured correctly, bud the classes are not found (class not found exception). Here is my code: JNLP: <?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.0+" codebase="." href=""> <information> <title>KeystoreTestApplet</title> <vendor>Paulie</vendor> </information> <resources> <!-- Application Resources --> <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se"/> <jar

问题 What is the "next generation plugin" for Java and how is it different from the classic plugin? Strangely, there is only one generic plugin on Mac OS X, so is this distinction only on Windows, or does linux also have two plugins? I also noticed that Firefox is only telling me to update the classic plugin, so I must wonder how different the two plugins are if only one can be compromised. Or else Firefox is making a mistake, and they're both vulnerable. I am also interested if this distinction

问题 I've been tearing my hair out for several days now trying to figure out just why the heck this never seems to work! First off, here is my config: Windows 7 x64 JDK 7 x86 JRE 7 x86 Firefox x86 Rails 3 served by Thin Java settings are such that the "next generation plugin" isn't active (but it keeps reactivating itself somehow!!!) At first I tried RXTX but I kept on getting "no class found" errors. I've now moved on to winjcom. The error I'm now getting is this: java.security

问题 I've trying to read and write a file from an applet so if I run the applet from my appletviewer it is possible for me to read/write a file but when I try to do it from my browser I get a security exception. Any idea how to do this? 回答1: Is it possible to read/write a file from an applet Yes, but you need to sign the applet and get approval from the user. Some useful links: How can an Applet read files on the local file system (from coderanch.com) Essentials, Part 1, Lesson 6: File Access and

问题 It is years since I have worked in Java (that's my excuse). I am trying to launch a Java Swing UI as an Applet (previously done via Web Start). I have modified the jnlp file to reflect the changes that I know are necessary for an applet (e.g. using applet-desc instead of application-desc). Inside the <resources> tag in the jnlp file we set system properties like this: <property name="java.security.auth.login.config" value="$$context/app/auth.conf"/> In the init method of the main class we try

问题 Due to a small implementation mistake I discovered how quickly I could reach a Java heap space issue now the bug is fixed everything is fine but it did get me looking into how to solve this and I foudn multiple solution such as java -Xms5m -Xmx15m MyApp the problem is that this changes the java memory on my computer, but I'm working on a Applet that is going to be used in a webrowser. Therefore, is there a way, at RUNTIME in an APPLET to change the heap size ? 回答1: You can add parameters to

问题 I've a signed applet (which verifies correctly with jarsigner ) that for some reason will not allow copy and paste from the system clipboard into a JTextField despite the documentation telling me that it is supposed to work for signed applets. Furthermore, I've other applets which are signed with the same keyfile that do let me copy and paste text. I have searched high and low on the internet and can't seem to find any clues. What is making me pull my hair out is that there seems to be no way

问题 I have an applet which was running 1/2 year ago. Now i needed to 'reactivate' it however for an unknown reason it is not working anymore. Here are the specs: JNLP based NG Applet Tomcat 7 JRE 1.7.0_25 Firefox 22 and Chrome 28 This is the error I get: MissingFieldException[ The following required field is missing from the launch file: <jnlp>] at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source) at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source) at com.sun.javaws.jnl
