Because Mac OS X ships with the Jar Launcher application, the end user needs only double click on the jar file and the application will launch. See Also: Art Crafts Show detailsSometimes, you may want to make your own libraries generally availableIn the case of the Java Sound Demo, the file JavaSoundDemo.jar is executable. For Mac OS X: Click on the 'Apple' menu in the upper-left corner of the screen -> 'System Preferences.' -> 'Java'.Launch.main(Launch.java:28) 6 it should be there asking to be allowed allow it then go back to the jar file and launch it if you dont have java in your mac how it comes with it 14 May 27, 2021. When you are done using the Java applet, you should change the Java 'Security Level' back to 'High' if you had lowered it down to 'Medium' earlier. You may need to click on it to start it. The Java applet should load OK now.
Check Console for possible errors. Jar file cannot be launched. Versioning change- I get a message saying The java. Paid security updates for Oracle customers ended in April 2015. Public support and security updates for Java 1.5 ended in November 2009. For example,Java 5 was first available on Apple Mac OS X 10.4 (Tiger) and was the default version of Java installed on Apple Mac OS X 10.5 (Leopard).
All labels, menus and dialogues have to be translated. How do I use objects from the standard library classes?For other languages, you will have to make your own translation. For system level access (allUsers and all projects) you can use the "userlib" directory.For user level access (all projects for a single user) you canUse the Preferences Dialogue to add a library, and for accessibilityFrom a single project you can create or add an archive to a project's "+libs" directory.
Let's say you want to make a language setting for Elvish. Create a new directory for the language you want. These contain all the language dependent texts. Here is how.In the lib directory, you will find subdirectories named "english", "german" and "swedish" and so on.
Someone out there might just be looking for a translation into your language, too. Once you have done that, you can switch the Elvish language setting on as described above, using the property setting:If you do this, we would be very grateful if you would send us your language files for inclusion into the BlueJ distribution. Edit each of those files and translate all the texts in them to Elvish (keeping the format of the files as it is), then run the "native2ascii" utility that comes with the JDK to convert the files to the correct format. Then copy all the files out of one of the other language directories into your new language directory.
The easiest way to do this is to start your web browser, openThe local documentation (by choosing "Open File.") and thenCopy and paste the URL from the browser into the BlueJ preferences field.BlueJ has two files in which in stores its configuration properties. Here, you need toPut the URL of your local copy of the documentation. You willSee a field labelled "JDK documentation URL".
On Windows Vista, 7, 8: C:\Users\ your-user-name\bluej\bluej.properties The "bluej.properties" file is a per-user configuration file stored in a different place on different systems: On Windows and LinuxIt is stored in the "lib" subdirectory of wherever you installed BlueJ.( On Mac OS X / macOS, it is found in the application bundle.)Usually, you will not want to edit bluej.defs unless you are a system administratorConfiguring an installation for many users.

How can I pass arguments to the Java Virtual Machine which BlueJ runs on?BlueJ actually runs two Java VMs: One is for BlueJ itself, and the other runs user code (for instance if you instantiate a class the resulting object is created in the user VM).To specify arguments for the user VM, use the bluej.vm.args property in bluej.defs (see where BlueJ stores its configuraiton).To specify VM arguments for the primary VM, you need to do something different according to the operating system you are using: On Linux and similar systems: your-home-directory/.bluej/bluej.propertiesNote that ".bluej" is normally an invisible directory.Properties set in bluej.properties override those in bluej.defs.You can edit both of these files using a standard text editor.On Windows you can use the Notepad application to edit the files,But you will need to select "All files" as the file type in the "Open file" dialog.Furthermore, you may need to save the file to a different location (using "save as") and thenCopy it over the original file using the Windows Explorer if you are unable to save over the originalFile directly. On Mac OS X / macOS: /User/ your-user-name/Library/Preferences/org.bluej/bluej.propertiesFor OS X 10.7 (Lion) and newer, please see this page for how to access your Library folder (which is otherwise hidden).
Expand the "Root" tree and then the "Java" tree, and the "Properties" tree appears below. Mac OS X / macOS: Control-click the BlueJ icon, and choose "show package contents" from the popup menu then, double-click the Contents folder, and then the Info.plist file (which should cause the properties editor to open). Linux/Unix/equivalent: edit the "bluej" shell script which is created by the installer (in the directory where you installed BlueJ), and modify the last line (which launches BlueJ).
(On Windows, recent BlueJ versions instead use a communication method called "shared memory", however, BlueJ will fall back to using TCP/IP if shared memory fails for some reason.)Firewalls generally take one of two approaches to blocking network traffic. Although this communication doesn't go over the network, some firewall software will block this communication which inhibits BlueJ operation. The communication occurs between two processes running on your computer - one is for BlueJ itself, and the other is for a "debug VM" which runs your program. How can I specify the file encoding that BlueJ uses?BlueJ uses TCP/IP socket communication as part of its normal operation. Before you can do this you need to have the Apple Developer Tools installed - the Property List Editor is part of the developer tools you can find them on the Mac OS installation disc.Be warned that changing the Java VM arguments is generally unnecessary and if done improperly can prevent BlueJ from functioning correctly. You can also create a new key "VMOptions" as a child of the "Java" tree, and specify additional command-line arguments as its value.
Some firewalls only block incoming connection attempts while other firewalls may also block outbound connections.For BlueJ to work, communication must be allowed when both the source and destination IP address is 127.0.0.1, which is the "loopback" address (i.e. A common combination approach is to allow setting specific source/destination rules on a per-program basis. The second approach is to block traffic on a per-program basis.
Note that BlueJ must be allowed to make outbound connections (or "act as a client") as well as receive incoming connections (or "act as a server").If your firewall sets rules on a per-program basis, the program you should apply the rules to will usually be the bluej launcher ( bluej.
