An applet is a little application program. Prior to the World Wide Web, the built-in writing and drawing programs that came with Windows were sometimes called "applets." On the Web, using Java, the object-oriented programming language, an applet is a small program that can be sent along with a Web page to a user. Java applets can perform interactive animations, immediate calculations, or other simple tasks without having to send a user request back to the server.

If other languages are compiled to Java bytecodes, how does that affect the applet security model? Examples Tiny applet examples that demonstrate the security features of your web browser. Glossary Terms used in this FAQ. See Also Other references on Java security

Sun's appletviewer allows applets to read files that are named on the access control list for reading. The access control list for reading is null by default, in the JDK. You can allow applets to read directories or files by naming them in the acl.read property in your ~/.hotjava/properties file. Note: The "~" (tilde) symbol is used on UNIX systems to refer to your home directory. If you install a web browser on your F:\ drive on your PC, and create a top-level directory named .

Sun's appletviewer allows applets to write files that are named on the access control list for writing. The access control list for writing is empty by default. You can allow applets to write to your /tmp directory by setting the acl.write property in your ~/.hotjava/properties file: acl.write=/tmp You can allow applets to write to a particular file by naming it explicitly: acl.write=/home/me/somedir/somefile Use : to separate entries: acl.

There is no explicit support in the JDK applet API for persistent state on the client side. However, an applet can maintain its own persistent state on the server side. That is, it can create files on the server side and read files from the server side.

No, applets loaded over the net are not allowed to start programs on the client. That is, an applet that you visit can't start some rogue process on your PC. In UNIX terminology, applets are not allowed to exec or fork processes. In particular, this means that applets can't invoke some program to list the contents of your file system, and it means that applets can't invoke System.exit() in an attempt to kill your web browser.

This applet tries to create a class of its own in the java.net namespace, but it can't. This example will not compile with the Java compilers that conform to the Java language specification. Windows:

For example, if your applet tag looks like: <applet code="video.class" archive="video.zip" width="177" height="145" align="center"> <param name="cabbase" value="video.cab"> <param name="src" value="http://123.123.123.123:1000"> </applet> You would enter something like the following in the english.txt file: banner.code=video.class banner.parameters=video.txt banner.width=177 banner.height=145 banner.fill=true and then create the file video.

Ans: Yes, we can... but we should caution you that there are still a lot of old browsers out there that are not Java-enabled. Older AOL browsers, for example, have a devil of a time with Java. We are frankly looking forward to the time when the whole web is fully utilizing the interactive capabilities of the platform-independent language and world of Java. Ans: We have an excellent form script in our CGI Bin, written in perl.

Applets are not allowed to open network connections to any computer, except for the host that provided the .class files. This is either the host where the html page came from, or the host specified in the codebase parameter in the applet tag, with codebase taking precendence. For example, if you try to do this from an applet that did not originate from the machine foo.com, it will fail with a security exception: Socket s = new Socket("foo.com", 25, true);

Be sure to name the originating host exactly as it was specified when the applet was loaded into the browser. That is, if you load an HTML page using the URL http://foo.state.edu/~me/appletPage.html then your applet will be able to connect to its host only by using the name foo.state.edu. Using the IP address for foo.state.edu won't work, and using a "shorthand" form of the host name, like foo.state instead of foo.state.edu, won't work.

Applets loaded over the net are loaded by the applet class loader. For example, the appletviewer's applet class loader is implemented by the class sun.applet.AppletClassLoader. The class loader enforces the Java name space hierarchy. The class loader guarantees that a unique namespace exists for classes that come from the local file system, and that a unique namespace exists for each network source.

The applet security manager is the Java mechanism for enforcing the applet restrictions described above. The appletviewer's applet security manager is implemented by sun.applet.AppletSecurity. A browser may only have one security manager. The security manager is established at startup, and it cannot thereafter be replaced, overloaded, overridden, or extended. Applets cannot create or reference their own security manager.

Glossary of terms used in this FAQ Applet A Java program that is run from inside a web browser. The html page loaded into the web browser contains an <applet> tag, which tells the browser where to find the Java .class files. For example, Standalone Java application A Java program that is run by invoking the java interpreter. For example, Server The computer that hosts the web page that contains an applet. The .class files that make up the applet, and the .

applet is a small computer program that runs inside a web browser. Because the program is often downloaded over the Internet, your web browser watches over the applet to make sure it doesn't do anything unusual. For an extra measure of security, Voice Tool applets are digitally signed, meaning that no one can forge Voice Tool's identity or alter an applet coming from the Voice Tools server.

Basically you need to attach (see the Target | Attach... menu item from the menubar, and the resulting Attach Dialog) to the Java Plugin. See Applet Debugging Support from Sun, for JDK 1.6, JDK 1.5 or JDK 1.4, on how to configure the Java Plugin to support debugging (and being attached to by JDebugTool).

You receive a User ID immediately upon purchase, which entitles you to 90-day access to the Log-In area. From there, you download the kit in a .zip file. In case you screw up, you can also go back and get extra copies of the kit any time at all during that 90 days -- and if it is after that, just email us with your ClickBank ticket number, and we'll send a new kit to any existing client via email.

Java is an object-oriented programming language and an applet is a little application. A Java applet is a small program that can be sent along with a web page to a browser. The Java program is then run from inside the web browser. Java applets perform simple tasks without having to send a user request back to the server.

If you want resizing behavior from an applet, you should launch an external frame that can be resized independently. Browsers don't support resizing of embedded panels. For the extremely tricky: have the browser reload the page with the applet when the browser resizes using new values for width and height (probably not what you want most of the time). You would need javascript to generate a page dynamically using document.write("...") when the browser resizes. Not recommended.

JDK 1.1 introduced the notion of a "trusted applet" which is one that has been cryptographically-signed to guarantee its origin and make it tamper resistant. Trusted applets can be granted more system access privileges than untrusted applets. Java was designed with security in mind. The security features make it very difficult, probably impossible, to attach a virus (self- copying code) to a Java applet. As far as is known, there has never been a Java virus.

An APPLET element is the HTML instruction that embeds an applet into a web page. In this case, it's simply the piece of code that displays a MoneyToys™ calculator in your web page.

The applet is a Java program that needs a computer with a JVM (Java Virtual Machine) installed. Before to play with sw3d you should be sure that a JVM is installed in your system.

In principle, browser-based applets could be developed for a more lightweight version, though this is not immediately on our research trajectory... We would nevertheless be interested in advising anyone who wanted to develop this from our open source code! BuddySpace was not developed with this in mind, so there can appear some problems while developing the applet version; e.g. the maps which need to be stored in a file.

The verifier is independent of Sun's reference implementation of the Java compiler and the high-level specification of the Java language. It verifies bytecodes generated by other Java compilers. It also verifies bytecodes generated by compiling other languages into the bytecode format. Bytecodes imported over the net that pass the verifier can be trusted to run on the Java virtual machine.

Yes. You can use the SimplePlayerApplet that is included in the jmf.jar file or write your own. See SimplePlayerApplet.
