Doing statistics in java?

Hey all,
A quick question, what is the easiest (and most mainstream) classes and/or package to do very basic statistics and data analysis in java?
I'm just looking for things like mean, median, std, etc. I was surprised not to see them in the java.lang.Math class.
aight.

Cannot open Photoshop: get error: To open "Adobe Photoshop CS5.app," you need a Java SE 6 runtime. Would you like to install one now? However installing Java SE 6 runtime does not fix nor does installing Oracle Java SE 7. Adobe says Apple is problem.

Searching the internet for solutions to this and some discussion with Adobe.
Adobe say Photoshop does not use java so it should not be asking for a java runtime.
The question is how can I stop Photoshop asking to install java since Photoshop does not need or use Java to run?
Found various links that might be helpful:

However as I have Oracle Java SE 7 installed and SE 6 is deprecated and no longer supported for security reasons.
Apple is actually responsible for Java 6's security. They take Oracle's code and do whatever is needed to make it compatible with Apple's OS. Java 6 is still getting security updates from Apple. Versions 6 and 7 can also exist on the same drive. They won't interfere with each other.
Also I am assured in no uncertain terms by Chris Cox over at Adobe that Photoshop CS 5 does not use java at all and that the java error message and so called dependency is just an error on the part of Apple.
I did find a topic where Chris stated that for CS6, which I know is true. I've installed CS6 (and CC) on a newly formatted drive in Mountain Lion, and neither made any mention of requiring Java. Could have sworn CS5.5 and earlier did you Java for a few functions. Though I likely only assumed that since that version and earlier always causes a prompt to install Java if it isn't already on the drive.
So is there any way to run Photoshop with SE 7 only installed or even better with no java installed?
It doesn't really matter much if Java is installed. Java 6 should put an app in the Utilities folder by the name of Java Preferences. Open that, and you can completely disable it by undoing the check boxes.
Perhaps there is a way to make OS X stop thinking it needs java SE 6 to run Photoshop CS 5.
Apple would have to make a change to the OS itself. It's a not a user accessible setting.

Version 3.6.14 has a bug & does not support Java to play Pogo games - How do I install a earlier version?

Pogo games plays on Java - the last version of Firefox 3.16.14 has a bug that does not support Java - I have been instructed by Pogo to install an earlier version of Firefox. How do I do that?

Firefox 3.6.15 was just released to fix that Bug.
You can use Help > '''Check for Updates''' to trigger an update to Firefox 3.6.15.

Does NW04s full java edition run on XP?

I am installing NW04s full java version on XP and I get a warning saying that my OS version is not supported. Does NW04s full java install runs on XP???
the warning message I get says that only Windows 2003 is supported.

Hi
I've installed it on XP Home and it works fine. But as per SAP, it supports
Operating System: Windows 2000 (Service Pack 3); Windows XP Professional (Service Pack 1) or Windows Server 2003
Here you check the requirement

Does iTunes require Java to run?

Does apple support java script

Does apple support java script

Yes - in Safari Preferences>Security tab, make sure there is a tick against 'Enable JavaScript'. There's probably a similar preferences setting if you run another browser.

Does it support Java 5

does it support Java 1.5 that is released now?

As mentioned Java Studio Creator comes with its own JRE so you don't have to find/install one. You can start Creator with the -jdkhome < JAVA_5_HOME > , but this is not supported.
In your Java coding (backing files), you cannot use the new language features (generics, annotations, for loop, etc...) or any new java 5 APIs as it would require a Java 5-capable application server. No AS supports Java 5 yet.

I have recently purchased the latest ipad. Got to say I am extremely dissapointed that it does not support Java or Flash which are platforms needed to do online business banking. I am now faced with ditching it and replacing it with a competitors product

I have recently purchased the latest ipad. Got to say I am extremely dissapointed that it does not support Java or flash which are platforms needed to do online business banking. I am now faced with ditching an expensive toy for a competitors product that offers full business functionallity. Is there any way round this ? It seems extremely bad form on apples part not to support this or make it very clear of the products limitations at the time of purchase.

Well, my bank has an app but the website does not use Flash or Java. While my credit union doesn't have an app, their website doesn't require Flash or Java either.
I pay all my bills online, bank, and access my brokerage accounts. None of the sites I have encountered require Flash or Java. Some government sites do require Flash so I use Photon, it's a browser that does Flash content very well. So you might check out some alternatives browsers.
Otherwise I suppose you will either dump you bank, your iPad, or just not do online banking.

Video capture does not work Java 1.5 or 1.6

I could not run jmstudio on 1.5, but on 1.6 I could, and jmregistry says there is a device with a Locator "v4l://0" and jmstudio can display the video. Yet my old program that worked with Java 1.4 can not now capture the video any more, createDataSource(locator) in the code:
locator = MediaLocator("v4l://0");
source = javax.media.Manager.createDataSource(locator);
throws NoDataSourceException, that says something about "Could not configure video device". Is the code bad? Or is there something other broken? JMFHOME is set correctly.

Where is your jmf.properties file? Do you have the performance pack installed?
Does JMStudio work. (if you're on linux w/ java 5.0 use: java -Dawt.toolkit=sun.awt.motif.MToolkit JMStudio)
My bet is that you don't have jmf.properties in your current dir or the camera hasn't been added to your properties.
Another idea:
try this before your code:
try {
Class.forName("V4LAuto").newInstance();
} catch(Exception e) {}in order to autodetect the camera.
Peace

Does Firefox support java applets if the "Next generation plugin" is disabled via the Java plugin control panel.

I'm still trying to get a definitive answer to this question.
My applet is not "Next Generation compliant". When we run our applet in Internet Explorer it runs fine as long as we disable the "Next Generation Plugin" via the Java plugin control panel. However our applet does not run in Firefox if the "next generation applet" is disabled.
Is it a requirement that if I want to run an applet in Firefox 3.6.x or higher that the "next generation plugin" be enabled via the Java plugin control panel.

Current Firefox versions (3.6 and later) can only run Java applets via the Next Generation plugin.

Why can't I run the latest Java on Firefox to operate my network camera? It does not find Java. Please Help!!

I just installed a network camera in my home correctly and signed in to view what was on the camera. But after logging in , info comes up with" cannot find Java" with an install button. I have the latest update of Java and the Firefox browser. There is no red block in the search bar that asks me to allow the site to use Java nor does it ask me to allow the site. I did uncheck the box in the control panel as it tells me to do in Java so that it asks me to use Java. Nothing works. I am so tired of installing and uninstalling, clearing my cache. Opening and closing my browser and reading info to fix this. I just want to be able to view what my camera films. Nothing on the firefox site answers or solves my problem. And believe me I've tried til my head is spinning. Someone has to have an answer. I need a vacation after this...Lol...
Thanks...

The Java plugin doesn't show in the System Details List.
Is 32 bit Java installed on your computer?
You can find the latest Java version on the Oracle website.<br />

You need the 32 bit JRE for Firefox.

What does the statement: "Java has a standard!" mean?

I'am writing a academic work. For that I need to compare Java and PHP. I found the statement "Java has a standard!" as advantage on a webpage, but what does it exactly mean???

I'm not being facetious or trying to brush off your question. If you want to know what someone meant when they said something, ask them. It's the most direct line and gives the highest probability of getting a useful, accurate answer to your question.

Ktoolbar does not recognize "java.util.Calendar"

Hi!
Although http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXRPC4.html says that java.util.Calendar is supported, ktoolbar errors out with
error: Found unknown simple type: java.util.Calendar
What's wrong? WSDL not compatible with Java ME?
any help/hint is very much appreciated,
regards Florian

To be honest, I am a bit lost.
I am beginning / trying to develop a mobile app using WTK / Java ME which uses a web service; the WSDL is here: http://www.pegel-mainz.de/WSDL/v3.0/iLON100.WSDL
Running ktoolbar's stub generator with a local copy of this file, I get the error above, but with a simple MIDlet which just says "Hi", everything builds and runs fine.
Funny thing, at least for me - or make that "irritating":
There is no "Stub" in the generated files. The one class which at least extends "java.rmi.Remote" is "MainSoapPort", but that is only an interface.
But in all tutorials/docs so far I find these Stub-classes to instantiate the service!
I guess I am doing something fundamentally wrong.
Any advice/hint/help/link?
It's very much appreciated (as I'm lost atm)
regards,
Florian

Windows XP does not support Java!

I was not surprised to see the statement from Microsoft that they will remove the JVM from their new operating system Windows XP, as it is "unecessary files for the user".
This causes a huge problem for all companies basing themselves on making applets. The reason for using applets is to provide web functionality without having to download plug-ins, but now this is no longer workable.
As a solution I request that Sun should come to the rescue here, as Microsoft surely will not be helpful.
What we need is a TINY file that will replace the functionality of the MS Java for the Internet Explorer. No huge 1.3 libraries, only the most basic things needed to run 1.1 applets like the MS virtual machine could. This system should be EXTREMELY easy to install for the end user. Just one click, and only the very, very basic files needed to replace the functionality should be installed. And only for the browser, to save space.
Basically what we need is a Java applet viewer plugin for Internet Explorer, that downloads extremely fast and that has installation procedures almost invisible to the end-user.
I emphasize on TINY (no 5MB huge beast!) and EXTREMELY easy to install. I am aware there exists solutions today, but they do not follow these criterias. This would be like a Java Browser Micro Edition for applets. Also, new VMs seem to be almost in practice non-functinal running applets written for Java 1.0 or 1.1, as we have seen in Netscape 6 which can run only a few existing applets, and very poorly. Please use the 1.1. standard, this will also save downloading time.
I expect Sun to take this seriously, as an applet free web would surely void a lot of work put into this branch of Java. And as a Java developer through several years, I would not think twice leaving Java in favour of C# if Sun does not provide a web browser solution for me, and everyone else depending on applets on the net. Not because I want to, but I see no other real world functional options now.

As a solution I request that Sun should come to the rescue here, as Microsoft surely will not be helpful.<<<You are right. Sun should come to the rescue here. Sun is not only helping us, but also helping Sun itself.

Just one click, and only the very, very basic files needed to replace the functionality should be installed.<<<Good spec!!!
I expect Sun to take this seriously, as an applet free web would surely void a lot of work put into this branch of Java. <<<To get Sun's attention, we should help Sun realize that Java will become un-popular, maybe even disappears, because of this. I am not sure they really care there is a lot of work put into this branch of Java (sorry if I am wrong).
I just don't understand why this type of solution is not available today. Everybody (including a guy like me who is always in the dark) could see what MS would do even two years ago.
Sun, if you don't give us a solution, I will switch to C#, "Not because I want to, but I see no other real world functional options now."
Did I get somebody's attention? Could we get more people to talk to Sun?

Does JVM variable java.library.path make sense from native code?

Hello all,
Well, everybody loads native library from the Java side by calling System.loadLibrary("myNative").
But what if, for example, myNative.dll loads another two libraries itself?
Suppose, when I call java method "initMyNative", it in turn call native function Java_initMyNative(...). That Java_initMyNative(...) wants to load two native libraries and make: HINSTANCE lib01 = LoadLibrary("auxlib01.dll"); // LoadLibrary from capital, it's Win function!
HINSTANCE lib02 = LoadLibrary("auxlib02.dll"); // LoadLibrary from capital, it's Win function!As specified, native LoadLibrary call will look for auxlib01.dll and auxlib02.dll in catalogs which are enumerated in system variable PATH, current catalog.
Does java.library.path make any sense on order of such search?
If not, is there any way of flexible configuring of the catalog in which to look auxlib01.dll and auxlib02.dll for?
I see some ways:
* changing system variable PATH - not flexible
* passing content of java.library.path into native code, parsing it and looking for auxlib01.dll and auxlib02.dll in each catalog listed in java.library.path - too heavy
I hope there is more smart way to do that.
Thanks, Alex

Thank you Shane for your reply. I actually didnt have to create 2 jar files, one for Java files and one for the dll file. I got an idea from your post and referenced the same jar file twice by saying:
<j2se version="1.2+" />
<jar href="HelloWorld.jar"/>
<nativelib href="HelloWorld.jar"></nativelib>
and by saying that the jnlp file started working from the browser.
Again, thanks a lot for your replies.
Thanks
Nick
