问题 I know you ca specify a file that is going to override the java.security f java -Djava.security.properties=myProperties How can I set this parameter in a JNLP file? 回答1: Properties in JNLP file you can set using this tag: <property name="key" value="overwritten"/> But you can't set java.security.properties in JNLP. Not all properties are allowed to set in jnlp. For more info see here. Why do you need to change this property? 来源： https://stackoverflow.com/questions/34998336/java-security

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 have recently put together a JWS application which gets it's argument from a dynamically created JNLP file (details can be found here). It's all good except the application ignores the argument (starts without loading the specified number) on my system (linux x86_64). It seems however that the JWS application exactly as intended on the win_64 machine of a colleague of mine. This is rather interesting as I couldn't replicate his success on another similar win_64. To make things more exciting

问题 I have Windows 10 pro. x64. I have jnlp file, that works on many different laptops, but not mine. So usually jnlp file opens a window with application. Not on mine machine. When i double click on jnlp or run it using jawaws file.jnlp what happens is Java(TM) web launcher and Java (TM ) Web Start Launcher is active in processes in task manager.. So, each time i run jnlp program, it runs web launcher and web start launcher but doesn't run program. What is curious, sometimes but seldomly, it

问题 I have this class called PollFrame that extends JFrame in a file called PollFrame.java . PollFrame contains a form. I have an applet, which has a button in it. When the button is clicked, I want the PollFrame to be displayed. I set the ActionPerformed as: Pollframe poll = new PollFrame(); // This initializes the form poll.setVisible(true); However, when I click the button, I get the following error : Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied

问题 I have a serious problem with Java Web Start that I can't get my head around. The situation is the following: I have a JavaFX app, written Java8, that I want to deploy using Java WebStart. Until recently I used HTTP for communications with a server, and everthing worked fine. I could deploy the app using Web Start embedded in the browser or as a standalone app. However I have now changed the communication to use WebSockets. For this I am currently using the tyrus implementation. And now comes

问题 I have problem running a Java RCP application via Java Webstart. This works for others in the team, but not for me. (don't you just love those sort of problems) I believe the problem is that it is downloading the 32 bit version of the application, not the 64 bit. When I look at the webstart .log file on my machine I can see the following. !SESSION 2012-07-06 16:24:37.672 ----------------------------------------------- eclipse.buildId=unknown java.version=1.6.0_32 java.vendor=Sun Microsystems

问题 The fun from java 7u45 keeps on giving. This time it's a deadlock within webstart. This is happening very consistently (every time) launching a large application (~100 jars). Has anyone else run into this or know of any workarounds? Other than reverting to 1.7.0_40? Thanks, Found one Java-level deadlock: ============================= "Java Web Start Main Thread": waiting to lock monitor 0x066368bc (object 0x29e65428, a java.lang.Class), which is held by "Finalizer" "Finalizer": waiting to

问题 I'm facing a problem here. I want to use a special version to run our java webstart application but just for one jnlp. ("It was tested, ... blabla we can't use a new version... blabla" by random windbag) So I tried to configure our JNLP like this: <resources> <j2se version="1.6.0_29" href="http://java.oracle.com/products/autodl/j2se"/> ... </resources> When I start this jnlp now I get following Error even if the right Java is installed: Error: The application has requested a version of the

问题 I am using Java Web Start to launch a Java application that depends on some third party native libraries. These native libraries then subsequently load another native library ( commonLib ) as their dependency using LoadLibrary/dlopen. When not using Web Start, everything works as expected when the native libraries are located in the same directory. Web Start, however, requires the native libraries to be packed in a jar file and referenced in the jnlp file, which I did: <!-- Windows OS -->
