As of Jenkins version 2.176.3, there is option enabled when "Launch agent by connecting it to the master" which is same as "launch agent via java web start" once you enable the "Manage Jenkins => Configure Global Security => Agents => TCP port for inbound agents" as mentioned above. e.g. Fixed: 50000

Create a shortcut. Move the shortcut into C:\ProgramData\Microsoft\Windows\Start Menu\Programs. Then click on the start menu and drag and drop your newly added icon wherever you like. Works on my copy of Windows 10 and avoids the CMD Window.

Specifically, I have a class Task (currently implements Runnable) in a file Task.java. My main application needs to be able to START this task on a thread, STOP (kill) the thread when it needs to, and sometimes KILL & RESTART the thread...

My first attempt was with ExecutorService but I can't seem to find a way for it restart a task. When I use .shutdownnow() any future call to .execute() fails because the ExecutorService is "shutdown"...

Option 2: Instead of letting the thread stop, have it wait and then when it receives notification you can allow it to do work again. This way the thread never stops and will never need to be restarted.

Regarding restarting: Even though a Thread can't be restarted, you can reuse your Runnable instance with a new thread if it has state and such you want to keep; that comes to the same thing. Just make sure your Runnable is designed to allow multiple calls to run.

So if you want a thread that you can shut down, you need to make sure it checks to see if it has been interrupted. If you want a thread that you can "shut down" and "restart" you can make a runnable that can take new tasks as was mentioned before.

You can't restart a thread so your best option is to save the current state of the object at the time the thread was stopped and when operations need to continue on that object you can recreate that object using the saved and then start the new thread.

If your task is performing some kind of action in a loop there is a way to pause/restart processing, but I think it would have to be outside what the Thread API currently offers. If its a single shot process I am not aware of any way to suspend/restart without running into API that has been deprecated or is no longer allowed.

If you want to pause the task simply attempt a lock from the main code (since you kept a reference handy). What this will do is wait for the loop to complete and not let it start another iteration (since the main thread is holding a lock). To restart the thread simply unlock from the main code, this will allow the task to resume its loops.

Sometimes if a Thread was started and it loaded a downside dynamic class which is processing with lots of Thread/currentThread sleep while ignoring interrupted Exception catch(es), one interrupt might not be enough to completely exit execution.

May I ask why you want to kill the thread and restart it? Why not just have it wait until its services are needed again? Java has synchronization mechanisms exactly for that purpose. The thread will be sleeping until the controller notifies it to continue executing.

This is a followup to my own previous question and I'm kind of embarassed to ask this... But anyway: how would you start a second JVM from a standalone Java program in a system-independent way? And without relying on for instance an env variable like JAVA_HOME as that might point to a different JRE than the one that is currently running. I came up with the following code which actually works but feels just a little awkward:

It's not clear to me that you would always want to use exactly the same parameters, classpath or whatever (especially -X kind of stuff - for example, why would the child need the same heap settings as its parents) when starting a secondary process.

To find the java executable that your code is currently running under (i.e. the 'path' variable in your question's sample code) there is a utility method within apache ant that can help you. You don't have to build your code with ant - just use it as a library, for this one method.

I am trying to use this GUI mod for a Minecraft Server. I wrote a batch file so the server can start with more RAM. When I run just the .jar file, no command window opens and it runs just fine (of course with about 256mb ram) I was reading online that javaw starts a jar file without a command-line-console. But when I use javaw, the command console opens, but when I close it the program remains open. this is my batch file:

You will always get the command window opening and closing because you are starting it inside a command window or batch script (which launches an implicit command window to run itself).In order not to get a command window you must open the file from "not a command window" i.e. an executable launcher.

A batch file is a way of starting the command prompt with the code pre-written, using javaw is a way of open then closing the prompt. Like I said a batch is a commands prompt you can't stop it from opening.

AFAIK, the "Enable Java content in the browser" checkbox on the Security tab of the Java Control Panel is controlling BOTH applets and web start. Indeed, on Mac, the equivalent checkbox is called "Enable applet plug-in and Web Start applications".

Click on the Chrome menu, and then select Settings.

At the bottom of Settings window, click Show advanced settings Scroll down to the Privacy section and click on Content Settings.

In the Content Settings panel, scroll down to the Plug-ins section.

Under the Plug-ins section, click Disable individual plug-ins.

In the Plugins panel, scroll to the Java section. Click Disable to disable the Java Plug-in.

Close and restart the browser to enable the changes.

Note: Alternatively, you can access the Plug-ins settings by typing about:plugins in the browser address bar.

I downloaded Netbeans 7.4 and Java 7 Update 51. I get the below error when I try to start Java DB or derby connection from Netbeans. This is on a windows 8 PC. I downloaded the version for windows xp 32 bit at work. It works fine. I am not sure what is missing.

I got a bit fed up with Oracle's approach to security lately. They seem to be trying to protect us from ourselves in ways that would be more appropriate to naive users than programmers. My view is that the code I put on my own machine should be able to do whatever it needs to. It's my fault if I put code there that does bad things. Clearly not a universally reliable perspective, but it's worked for me for about 35 years. On that basis, I add this to my /lib/security/java.policy file:

EDITAt fisrt glance it worked, the service started just fine, but when creating or starting a database in NB, i got the error Unable to connect. CAnnot establish a connection to jdbc:derby://localhost:1527/sampleAlthough i changed the pprt to 51527, it tries to connect to 1527

Create a folder for your Java program and open the folder with VS Code. Then in VS Code, create a new file and save it with the name Hello.java. When you open that file, the Java Language Server automatically starts loading, and you should see a language status item with a loading icon on the right side of the Status Bar showing the language status is busy. After it finishes loading, you can hover on the language status item and find the loading process has been finished successfully. You can also choose to pin the status item in the status bar.

You can download java from here. Here you will find different versions of java. Choose and download the one compatible with your operating system.

In computing, Java Web Start (also known as JavaWS, javaws or JAWS) is a deprecated framework developed by Sun Microsystems (now Oracle) that allows users to start application software for the Java Platform directly from the Internet using a web browser. The technology enables seamless version updating for globally distributed applications and greater control of memory allocation to the Java virtual machine.

The developer prepares a special XML file with JNLP extension. This file describes the application requirements, code location, parameters and additional permissions (if any). The browser downloads this file as any other and (following its MIME type, application/x-java-jnlp-file) opens it with Web Start tool. Web Start tool downloads all necessary resources and launches the application.

Java Web Start provides a series of classes in the javax.jnlp package which provide various services to the application. Sun designed most of these services with the aim of allowing carefully controlled access to resources (such as files and the system clipboard) while restricting the application to authorized operations.

Sun introduced version 1.0 of Web Start in March 2001,[5] while 64-bit Windows support was added only in Java 6[6] (later than 64-bit Java was first available). Since J2SE 1.4 Web Start comes as a default part of Java Runtime Environment (JRE) called javaws, computer administrators no longer have to install it separately.

Programmers often speak of the Java Network Launching Protocol (JNLP) interchangeably with the term "Web Start". The JNLP protocol, defined with an XML schema, specifies how to launch Java Web Start applications. JNLP consists of a set of rules defining how exactly to implement the launching mechanism. JNLP files include information such as the location of the jar package file and the name of the main class for the application, in addition to any other parameters for the program. A properly configured browser passes JNLP files to a Java Runtime Environment (JRE) which in turn downloads the application onto the user's machine and starts executing it. The development of JNLP took place under the Java Community Process as JSR 56. It includes the original 1.0 release, the subsequent 1.5 maintenance release, and as of 2006[update], the pending 6.0 maintenance release.[clarify] be457b7860
