The automatic disable is for Java (not javascript) INSIDE Safari.
Safari > Preferences > Security > [√] Enable Java
To check that Java is installed, open Java Preferences.app, available in your /Applications/Utilities folder
If Java is installed, it will show the version. If not Installed, you should be offered the option to download and Install it.
There is also a checkbox in Java Preferences for:
[√] Enable applet Plug-in and Web Start Applications (unchecked by default).
If you do not use Java inside your Browser for a few weeks, it will become disabled to protect against malware that downloads java.

How to check Java Card CC EAL version?

Hi friends..
I want to know, how to check the CC EAL version of our Java Card?..
Roughly, What is the different between Java Card CC EAL4 and Java Card CC EAL5?
Are both of them differentiated by Cryptography supported by each chip?..
I mean, whether or not Java Card CC EAL 4 support only Symmetric Key, while Java Card CC EAL 5 support both Symmetric and Asymmetric Key?..
Please correct me if i'm wrong.
Thanks

CC assurance level has nothing to do with support of cryptographic feature. Check out following link for more more information.

How to check Java Version while showing applet in browser?

Hello All,
We have an application which has client and server mechanism.
Our application can be accessed by any internet browser on any machine of the network but there is only one server in the network.
One of the functionality in the application is described below.
We do have one link in our application webpage. When user clicks on that link, the request goes to the server component which is running on different machine. Now server process the request and in responce we do show some images in applet window at the customer webpage.
Now problem is, when the client machine browser has some lower version of Java, we are not able to show the image but only shows a blank page.
What we want to do is to show some specific warning message when we find that the Java version at client machine is lower than required.
Can anybody please let me know how can I achieve this?
Thanks in Advance,
Jenish

Sun's latest versioning solution for applets and JWS apps. is [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html]. I also offer the [Java Version Checker Applet|http://pscode.org/jre.html] as an alternate way of ensuring a minimum major version of the JRE.

How to check Java installed in my system

Hi All
I new to java i have not some doubts
1)In my system I have this many JDK i dont know for this JDK what IDE version i need to download. I like to use netbeans which one should i need to download?
C:\Program Files\Java\jdk1.5.0_01
C:\Program Files\Java\jdk1.6.0_22
C:\Program Files\Java\jre1.5.0_01
C:\Program Files\Java\jre6
But i dont have any IDE to develop my java like eclipse or Netbean etc ,I have Only Jdeveloper 9.0.3.5
2)How to find apache tomcat server is installed in by PC or not how to test that ?
please know the installion steps also in need to install ..
Advance Thanks
Aarasu

I like to use netbeans which one should i need to download?You'd think you would go to the Netbeans website and find out, but I'm silly like that. Either a recent JDK 6 or the latest JDK 7 will do just fine. I would install Java anywhere except in program files. I install all my Java stuff in a directory called "java" myself, so I have C:\java\jdk6, c:\java\eclipse37, c:\java\tomcat7, etc. I never have to search for my stuff that way.
(of course being a proper computer savvy user I partioned my harddrive to reserve the C drive specifically for the OS only, so it is in fact e:\java).
2)How to find apache tomcat server is installed in by PC or not how to test that ?Use the search function of your OS of course. Its not even a Java related question.

How to check the Memory consumtions and time taken by a Java Program??

HI all,
I want to know how to check for the Memory Usage of an XML Parser.
See, a product was developed completely in DOM parser and now I am replacing that thing with SAX Parser Completely, because the DOM parser was taking huge memory as u may have guessed.
BUt the thig is that, now I want to check how much memory is being taken by the SAX parser alone and DOM parser alone so that I can compare them.
Can anyone suggest me how to do that ???
Thanx in Advance
Kaushik

Thanx boss ..thanx a lot
I tried that, but in the API docs, it is mentioned that freeMemory()Returns the amount of free memory "in the system"
and totalMemory() Returns the total amount of memory in the "Java Virtual Machine".
So if I compare both the Values then would it give the Correct result to me ???? Beacuse the freeMemory() gives the data in terms of the Host System whereas totalMemory() provides the data in terms of Java Virtual Machine ..... are they Same ?????
I think I am clear in explaining what exactly is going on my mind ...
Please clarify
Thanx again
Kaushik

How to check the JDK version of a compiled java file

can anybody tell me how to check the JDK version of a compiled java file ?
Edited by: gbhatia8 on Sep 9, 2010 7:04 AM

The major/minor version of the class file is the way to go.
Also, it's not necessary to write a separate program to get to those. javap prints them out when being passed the -v flag.
Note, however that "JDK version" is not a correct term, as I can create 1.4-compatible class files with a Java 6 JDK (by passing the -target flag to javac). Those won't look any different than .class files written with a 1.4 JDK.
