Can a Java Applet Access Local File System

问题

I am creating a java applet, that gets information out of a JAR file on my local file system, and creates a jpanel to display in the applet.

I am getting the applet to load correctly on the appletViewer in Eclipse, but it will not load whenever i launch the Html file i created.

The html file is points to the class files, also to the external jars.

Any Suggestions?

Thanks

回答1:

Yes, if the applet is signed with the jarsigner tool.

回答2:

Unless explicitly granted, an applet may not access the local file system.

"Will not load" sounds like you have a packaging error instead of a permission error. Have a look at the appletviewer logs.

回答3:

If you are using Netbeans then right click on your Applet project ->Properties->webstart-> clickon Enablewebstart ->customize->select radio self-signedby generatedkey->ok

then your job will be done
