Hi Javaexperts,

I am new to Java. In Command Prompt I cannot access javac. I am getting message: "javac" is not recognized as an internal or external command. I checked bin folder too ensure javac.exe file. 

Pls help!!!

Have you downloaded JDK? It's not recognizing the compiler..

where do you have your java filed placed in, are your source codes inside the bin directory? if so navigate to

bin directory , for eg, C:\j2sdk1.4.2_08\ bin and run the compiler from that directory..

You need to set up:
1. Add Java/bin folder to class path,
2. set to execute from anywhere (.;).
 Do these below.

Check where is Java installed; and get the path to java/bin folder. Similar to this one C:\jdk1.5.0_05\bin.

Right click on My Computer --> Advanced --> Environment Variable --> From Systems Variables, Highlight Path, and click on Edit, at the end of the line Add these .;C:\jdk1.5.0_05\bin
And OK ->OK

Exit your command prompt, and start again and type java -version, and you should get some results, esle something is wrong;

Quite guy,

I did what u suggested, still it is not working.

Quite Guy,

BTW, m learning the Helloworld.. "the first step of Java". Javac command is accepted as I followed ur instruction but soemthing else is appearing screen shot is attached below.

 

Quiteguy,

I got it,,, i made a mistake in typing Helloworld....

Thanks a lot

 

I gave a bad advice here, so guys I took it out :)

Eyefusion,
You need .java extension to compile. Just "javac Helloworld" won't compile.

Hehe,thanks LondonBridge.You're right. My bad.
And I  just complied few files using javac just a few days ago  for use in ObjectDB.
A  geeky story if you wanna hear:
I needed to load up a persistent-capable class files in ObjectDb''s explorer.I had the complied transient  class files nice and smooth. I also had  the .jdo  xml meta-data file inside the folder. I'm ready to enhance, right?
Apparently not. I keep getting persistent-aware classes which is of course no good.
I was going crazy for hours as it simply wont enhance.
Finally after hours of torture,A revelation occurred from god. He said,"yo, you saved "package.jdo" as "package.jdo.jdo."
Bingo. That fixed it.
