Any reason to use jdk 1.4 instead of jdk 5.0 on a java project?

That's what I'd assume too.\n\nIT departments have standards, and they want to make sure what's developed runs anywhere (even though you know that's not the case here), is maintainable by anyone, is common, etc...\n\nA good arguement FOR using 5.0 is that if there is some functionality/new methods/etc. that CONSIDERABLY improve performance, reduce programming effort, or reduce maintenance in YOUR PARTICULAR SITUATION, then I would talk to my boss about it.\n\nYou see, standards DON'T change unless there is a good reason to change them.  Saving a lot of money is certainly a reason to consider.\n\nBut, if there is NOT a compelling reason to use 5.0, then I agree with their position.

You need to download Java.

Something like this maybe:\n\n Runtime.getRuntime().exec("C:" + pathSeparator +\n"jdk1.3.1" + pathSeparator + "bin" + pathSeparator + "javac.exe " + file);  } catch(Exception e)  { e.printStackTrace();  }  }  }

No, in fact what I did, was uninstalled all of them, then I went to http://www.java.com and simply reinstalled the 5.9 version...\n\nI did it that way just in case I erased the old ones and it would make the 5.9 not work, and also to make sure I had the most up to date version and it installed correctly.\n\nHowever later I checked it on another computer, you can remove the old versions using windows add/remove in control panel.

try downloading \nJava JRE [1.5.0_06] (Java 2 Runtime Environment)

It sounds like you have a problem with your Java installation. I'd wipe the old one and reinstall the latest version available for your platform.

Try to use the last version of Java...

Yes surely you can. Initially the going may be a little tough, but definitely u can.\n\nkev is correct but IMHO  do not use NetBeans IDE at the very begining. In stead write programs in a text editor for some days.\n\nAlso get the following book.\n\nThe complete reference JAVA By Herbert Schildt. J2SE 5 edition. This is a must.\n\nThis site is still under construction. U may check it about a month or two later. I believe we shall be ready by then. There we shall definitely help people like u.\n\nhttp://defttips.googlepages.com/defttips\n\nIf u like I shall inform u as soon as we r ready.

You may need Java.  Download a Java update.

I used one once many years ago, but can't find it.  Here is one I found using Google:\n\nhttp://www.innovation.ch/java/java_compile.html

Try downloading the latest java uipdate (VJM I think - Virtual Java Machine).

I received a message regarding a java update about 10mins ago.\nMy version is now updated.\nI don't know if this will affect you but do a software update for java anyway.\nIt must cure some current issues.\n\nhttp://www.java.com/en/\n\n.

You're stuck with a 1.1 JDK (http://developer.apple.com/java/faq/  see no. 6).  You can use any text editor and use the apple JDK tools (I think they called them the "MRJ").  Obviously, you can't use any tools developed using Java 2 or later libraries (NetBeans, JDeveloper, JEdit, etc.).  Your Mac Classic days are numbered.  Sorry.

I am puzzled by your claim that you posess Java 6 because the latest version of the Java Runtime Environment (JRE) that I am aware of is 1.4.2.  I suggest that you visit http://java.sun.com/j2se/1.4.2/download.html and download the JRE (it's the third option; click where you see "Download J2SE JRE").  That ought to bring your java version to the latest version if that seems to be the problem.\n\nI must admit, that I'm neither sure what the problem here is, nor why those would be conflicting with each other, nor why it was suggested that updating java might fix this, but at least executing this course of action will eliminate "wrong java version" as the source of that error.\n\nI hope that's helpful at least a bit.

Do you have Java installed?

because it's way way outdated.\nTry Eclipse from eclipse.org.\nOr else, compile from the command line:\njavac *.java\nand then create the jar file, like so:\njar test.jar *.class
