Nov 30, 2018 jar2app. Jar2app is a Python 2/3 script that can easily convert any jar file into a Mac OS X app file. It seeks simplicity, and in fact can be run just like. Jar2app input.jar creating input.App in the process. No third-party libraries. Though simple and easy to use, there are loads of configurable options, such as setting icons, bundle names or bundling your own JRE/JDK.
I see that you're having some trouble using the Notes app on your MacBook Pro because it keeps freezing. I'd like to help out.
- Oct 08, 2013 In this tutorial, I'll show you how to convert executable jar files into mac os x.app bundles with my own launch script. The features include - Support for global menubar - Change icon in the.
- The next generation Java Plug-in is not enabled by default on Mac OS systems. So here are a few tips to enable the plug-in. Upgrade to a 6u17 based Java update. This support page from Apple might be helpful. Open the Java Preferences application and toggle setting to 'Run applets: in their own process'. Restart your browser and try viewing the.
Does this same issue happen if you create a test user and use the Notes app there? This is a great way to test if third-party issues are causing the problem or if it's the macOS. Here's how to set up a test user account: How to test an issue in another user account on your Mac
Also, test out the Notes app in safe mode. Sometimes just starting in safe mode and then starting normally again can resolve issues like this. Here's how to start in safe mode: Use safe mode to isolate issues with your Mac
Depending if the issues are resolved when testing out in these two modes, there are instructions in the article on how to proceed. You can also let us know the results, and we can help out. Let us know how it goes!
Cheers.

How do you reference the jar file in the HTML - can you show us the applet tag?
OK, thanks, that works fine. I get the applet for my simple test applet, but I get the �Start: applet not initialized� error with my more complex applet.
>How do you reference the jar file in the HTML - can you show us the applet tag?<
This is the tag in XCode:
<APPLET archive='Applet_Conduit_Fill.jar' code='Applet_Conduit_Fill' width=300 height=150>
Your browser does not support Java, so nothing is displayed.
</APPLET>
But my browsers DO support java, so what does this mean?
<APPLET archive='Applet_Conduit_Fill.jar' code='Applet_Conduit_Fill' width=550 height=650>
</APPLET>
and made sure the jar, class and html files were all in the same folder, then went to Dreamweaver and did Insert>Media>Applet and selected the class file. Now when I preview in Safari, the applet works as it should, but Modzilla and Netscape both give the exception:
java.lang.ClassNotFoundException: Applet_Condulet_Fill.class
and at the bottom there is the cryptic �Start: applet not initialized� message. Any insights as to why it should work in Safari but not the other browsers?
Is there a way to implement an application on a website without using an applet? For example, a simple box where a user can enter a number and the application will calculate and return an answer?
Thanks in advance.
The 'Your browser does not support Java, so nothing is displayed.' is just there in case the browser has no Java or Java turned off, in which case it would ignore the applet tag and display what's inside it (i.e., that message). It has no bearing on the problem at hand.
I had to create a new project in Dreamweaver and use the Terminal to create the class file (using javac) and the jar file (using jar cvfM �) and although I can get it to work fine in Safari, I still get the errors in Modzilla. I don�t get it. Other than turning java on in Modzilla, I can find no way to assign a java version, so I have to assume it is using the system version, java 1.6.0. Any insights? Thanks.
Are you really running Java 6 on the Mac? Then I wouldn't be surprised to encounter problems - it's still in development, after all.

Here is part of the console log (and yes, I am really running java 1.6 :-):

, it's called Applet_Conduit_Fill, so here it works the other way around from what I mentioned earlier (the class name should apparently not include the '.class' extension).The folder in the path:
/GAIA_G5/Users/chris/Desktop/TestDreamweaver/
contains the following files:
Applet_Conduit_Fill.class
Applet_Conduit_Fill.jar
Applet_Conduit_Fill.java
example1.html
so I don�t understand the error. I discovered some spaces in the path of the last attempt and thought that might have been the problem, but correcting it made no difference. Omitting the .class extension does show the whole class name in the error, but there is still an error somewhere.

The error message is indeed strange - is the Applet_Conduit_Fill.class file readable by the browser, e.g. if you enter its path into the URL field?
Yes, the jar file contains the class, java, and html files.
>The error message is indeed strange - is the Applet_Conduit_Fill.class file readable by the browser, e.g. if you enter its path into the URL field?<
It is readable in Safari, but when I attempt to read it in Modzilla, I get the following error in the console.log:

This means that the Java code has been compiled with a newer version of Java than the browser plugin can handle. Class files of version 50.0 are created by Java 6, so it seems that Mozilla uses at most the Java 5 plugin. You can check that by entering 'about lugins' in the Mozialla/Firefox URL field.
Assuming that the code doesn't use Java 6-only features you can compile it by using the -source and -target switches of javac. Then the class files are executable by older JVMs/browser plugins.
My version of Modzilla shows java 1.3.1 for the java Applet plugin enabler. It also gave me the warning that I don�t have the latest version, so I downloaded the latest version and got the same java version.

Good theory, and we may be getting closer here, but compiling the java code using:
javac -source 1.2 -target 1.2 Applet_Conduit_Fill.java
results in the following error in Modzilla:
