Hi Friends ,

I was having java 1.4 installed on my machine. Now , recently i upgraded to 1.5. However when i goto command prompt and type this :

> java -version

it still says 1.4 releated things.

Can someone let me know how would the new 1.5 come in effect. I need to use new 1.5 features like static imports , enums etc.

Thanks in Advance.

I don't feel that it should be in the Advanced forum
Please check your PATH variable. It probably contains a directory pointing to version 1.4 of your compiler.

Hi, You have to put the absolute path of the bin directory (in my case "C:\Archivos de programa\Java\jdk1.5.0\bin") in an environment varible called "path"; In windows have to check the system32 directory, if there are java.exe and javac.exe you have to move out them.

Hi Mike / Satou ,

I tried doing as told by you... But it didnt work out.

I moved java.exe , javaw.exe , javaws.exe from system32 folder and added an entry for PATH variable as C:\Program Files\Java\jdk1.5\bin

and then i went to cmd again and tried. Still its 1.4

Please help out.

Thanks

What exactly does your PATH environment variable contain now?
Did you restart the computer after changing the PATH?

You most likely need to put the new path pointing to the Java 1.5 JDK at the front of your PATH variable. I've seen a similar problem before when another program I've installed has modified my PATH for me and over-ridden the JDK that I had specified.

In short, your system will use the first JDK it finds in your PATH. So if you have

PATH = .;C:\Program Files\Java\jdk1.4.2\bin;C:\Program Files\Java\jdk1.5\bin

you system will use the 1.4.2 JDK.

If you find that this is the case, just remove the older one, or rearrange them so that 1.5 comes first.
 
I agree. Here's the link: http://aspose.com/file-tools
