• I don't know what to do about Java - my Mac is horribly slow, and I was advised to remove Java. But now it will not open Photoshop without Java.

  I don't know what to do about Java - my Mac is horribly slow, and I was advised to remove Java, it installs adware. The more I studied, the more information, I've seen say that most of the Web sites and software do not use Java on Mac more. So I deleted everything related with Java. But now it will not open Photoshop without Java. It will be safe if I get it directly from the Oracle site?

  You can download the installer for OS X directly from Oracle. Be sure to uncheck everything installs 'optional' which can appear at the beginning (I think on Windows it wants to install McAfee trial or the toolbar Bing - not really malware, more as desired and useless crud-ware).  I have a course Java JRE install on my MacBook Pro retina like some internal tools we have developed to work are currently java and I use a tool of u. Toronto called CytoScape is Java.  Sites Web will use Java Script, a very different beast and does not require a full Java or JRE install.  But with Java/JRE installed, just be sure of the source of any software that you download and install that is java based (as you should with all the software that you put on your machine).

  In addition, for PhotoShop, it says that you need the legacy Java 6 for OS X?  If so, then don't waste your time on the current version, just install that release 6 legacy.

  Hi Jerry,

  Welcome to the Microsoft community.

  Based on the information, you want to learn more about the help of SSV plugin Java TM, given that you have reinstalled Java and disabled using SSV plugin Java TM.

  TM Java Plug - in SSV helper is a plug-in which belongs to Java. Java is a programming language. You need what is called the Java runtime environment to run programs written in Java. The Plugin is part of that. A small number of Web sites also use this. If it affects the performance of the computer much you could turn it off, however, if you visit Web sites that use Java, you may need to enable it.

  For more information, see the article of the Java Support:

  It will be useful.

• What is the supported Java Version

  I tried to find information about what version of Java Adobe will officially support for ColdFusion 8.
  
  I'm considering upgrading the version of Java to the latest (update 5) but would not do if it means that I would have not supported.
  
  Does anyone know which versions of Java are supported for CF8?
  
  Thank you

• is an HTTP Post possible using webworks/widget SDK or what I should use Java widget?

  Hi all

  I use webworks and widget SDK to make a simple application where I need to do the following

  (1) open a site called www.mytest.com

  (2) display the following parameters with the request to open the site

  Login = true

  UserID = one

  password = b

  Is this possible using BlackBerry Widget SDK? I looked at the blackberry.invoke.BrowserArguments and I do not think that it allows that.

   

  Is this a limitation to the use of webworks? If so, that is the only alternative is to develop a widget of java and use the browser2 field?

   

  Thank you

  Parag

  Yes, you can...

  When you make an Ajax request, on your call to the open() of XMLHttpRequest objects method use the following:

  XMLHTTP. Send ('post', URL, true);

  XMLHTTP. Send (post_string);

  WHERE

  'post': your request method

  URL: the url to which the http request you

  true: to make it asynchronous (Note: this is the default behavior)

  post_string: is a urlencoded string containing all your post variables and their values like this

  "xc =" + encodeURI (element.value) + '& xd =' + encodeURI (element2.value)...

  You should be fine here as long as you know how to create an XMLHttpRequest object and can use GET, this should be familiar.

• Today, 26 September 2011: I finally decided to download version 6. I received a message that my java script is not compatible with this version. He did a search, and said that he could not find an update. I need Java script. What now?

  Using Window XP Pro with service pack 3 and all updates. I uninstalled version 6 and now back to version 4. 4 GB of ram and over a hundred gigs of storage. Don't use not Norton or McAfee. Check my settings, I find java is enabled, but still "java not installed" on many sites. I went back to version 4, so I can only load the info troubleshooting from there.

  It's not JavaScript which is incompatible / people with disabilities, this is the Java Console, which is incompatible or disabled. The Java Console is installed with every update of Java and is not necessary for most users; Read what follows in the Java Console

  • Also see-> http://kb.mozillazine.org/JavaScript_is_not_Java
  • Also see-> https://support.mozilla.com/en-US/kb/JavaScript
  • Also see-> http://www.htmlgoodies.com/beyond/javascript/article.php/3470971/Java-vs-JavaScript.htm

  Make sure your Java works at the following link. If Java runs on your system, it will detect the version that is installed on your system.

  Java Console
  
  Unless you do Java programming/development or debug web pages, Java applets, you don't need Java Console. Java Update will install a new Java Console with each update. Remove extensions Java Console has no effect on the operation of Java for web browsing. You can see, but not removethe Java Console extensions in Add-ons > Extensions. Console Java extensions can be removed safely manually by following the instructions in this article:

• What is the recommended API for reading/analysis of XML in Java files?

  Hello, everyone!
  
  In my application, I have to read a XML file. I think that Java has several APIs to parse XML files and as I am new to this, I would like to know from you what is the recommended Java for this API.
  
  Thank you.
  
  Marcos

  Unless you plan to edit nodes and I would recommend that you use a Sax parser, which is a lot less hunger of memory as a DOM parser. The DOM parser to read the entire document in memory for the manipulation of the user.
  If you are looking only to read the document and extract specific values then a DOM parser would be an exaggeration. If you are planning leave the document unchanged then a SAX parser is the way to go - a little more complex to write but worth the extra as it will be faster and more scalable.

• Firefox Java recived message - a pop up message

  Since firefox with a title bar that says - "Add-ons can cause problems. The body of the message "firefox has determined that the following modules are known to cause stability or security - Java (TM) platform SE 6 U23 problems' 6.0.230.5 For your protectoin, it is strongly recommended that you restart with these Add - ons disabled. "But when I watched the last digits of extension, FF said that the Java plugin, JRE versions under 1.6.0_31 or between 1.7.0 and 1.7.0_2 is the issue. I'm afraid that the pop-up that I received was not FF, because of the divergence of the version numbers.

  If you check the list of modules, you can find that you have a version lower than 1.6.0_31.

  Orange Firefox button or classic menu Tools > Modules > Plugins

  That's what I have for Java:

  Java (TM) Platform SE 6 U31 6.0.310.5
  
  Next-generation Java plug-in 1.6.0_31 for Mozilla browsers

  On the test page, it is shown as "Update 31": http://www.java.com/en/download/testjava.jsp

  I'm having a problem with firefox, play background music on some sites, it works with IE and other browsers, but not with fire fox, what html script or java I must add to the pages so that they play music?

  I am developing my pages front page and I know the music only works on IE, so if someone can tell me how to fix this because it is important that I use fire fox as my main browser.

  Hi madsman,

  Thank you for using Microsoft Windows forum

  For better support please give us the exact error code.

  This could well be a virus problem. If your step would be to run a full scan of PC online using the following link:
  http://OneCare.live.com/site/en-us/Center/whatsnew.htm
  Then, go to your Control Panel and open "Programs and features" and tell us what version of the Java Application you have.

  If you have a Version that is older, then you must remove the older version of "Programs and features" and install the latest version by visiting here: http://www.java.com/en/download/manual.jsp

  It is normally acceptable to load new versions of Java on top of older versions, but in this case we want to start over with a latest full version.

  Scroll down a bit to the "Download Windows Section" and download/install "Windows 7".

  After download/install this newer version. Close all windows and applications that may be running and "restart" your computer.

  Then click the link once more to return to the download page and select the link that reads "Check Java has been installed properly" If the application downloaded/installed correctly then this test will let know you that Java is working properly.

  Your last step would be to run a malware scan using this link:

• ORAAH Java API

  Hi do anyone knows if ORAAH comes with a Java API? Also outside installation guide guide and developers is there any other source material or tutorials available?

  Thank you!

  Marlene

  Hi Marlene,.

  Not sure what you mean by "Java API"; It is a widely used software R rJava, which is a general interface to R-Java - see the Homepage and download page of GUTS to learn more. There is also a small package of R type tutorial for use of rJava: helloJavaWorld.

  Regarding the materials, apart from those that you mention that there are also things in Chapter 7 of the Big Data connectors manual, which is part of the Big Data Appliance documentation.

  Hope this helps
