Executing from Console

Hi =)

I've just written a program with eclipse and running it from inside Eclipse works. But outside from console does not.

flaab@Debian ~/Desarrollo/Conexion/principal\ $ java Start

Exception in thread"main" java.lang.NoClassDefFoundError: Start (wrong name: principal/Start)

What might this be?

huh? if it runs inside eclipse then it should run through command prompt with no problem. post your code.

Try $ cd ~/Desarrollo/Conexion

$ java principal.Start

(assuming you have cwd in your classpath)

Hi flaab,

Just to clarify a bit, if running the program from the command line (terminal, bash, etc.), you either have to be within the directory the program was saved in; the said directory must be on your Java class path; or, you must specify the path when compiling and running the program like so:

javac -classpath .;C:\users\dac\classes;C:\tools\java\classes ...

(which I 'stole' from http://manticore.2y.net/doc/jdk1.1.8/docs/tooldocs/win32/javac.html)

Setting the path is OS specific, so take a look at Google and you should be able to set it up pretty quickly. That is, assuming that's what you want.
