Setting up JavaSDK1.3.1

[Redstar7]

Anyone here familiar with programming in Java2? I would like to start learning the language, so I went out, picked up a beginner's book, downloaded the SDK1.3.1, and now I am having problems setting it up to compile and run. What I've done is added a couple of lines in autoexec.bat like I'm supposed to do (that sets a PATH and CLASSPATH), but I still encounter error messages like this:

--When I type (at command prompt)
javac filename.java

-I get 'bad command or file name'.

--When I type
java filename

--or
java filename.java

-I get 'exception in thread "main" java.lang.NoClassDefFoundError: filename'.

I don't have any other java compiling programs to conflict with, and the path I set up in autoexec.bat leads to the folder where my source code is being saved. So I don't understand why the conflict is there. I'm using Win98SE.

Any suggestions?

You should post the autoexec.bat...

Both the files you are compiling and the javac.exe need to be in the path, somehow. Sounds like you don't have the actual /sdk-1.3.1/bin dir in your path.

If you're a beginner, you might wanna try coding with a java IDE (integraded development environment). There are some free ones like JCreator and JBuilder. I use JCreator because I like it better, plus since you already downloaded Java SDK, you won't need to download it again with JCreator. JBuilder includes the Java SDK so it's a bigger download.
