lab 1 - checkSync

[elisabet]

When I to run checkSync with the command line presented on the web
page, I get the following error:
[elisabet@ed-5355-18 lab1]$ java -cp /chalmers/courses/TDA600/
CheckSync/checkSync.jar:. edu.umd.cs.pugh.CheckSync PasswordApp

Could not find the main class: edu.umd.cs.pugh.CheckSync. Program

I can't even see the /chalmers/courses/ directory. Any suggestions?

Hej Elisabet,

/chalmers/courses/TDA600 seems to have changed to
/chalmers/groups/tda600. You might need to do "setup_course tda600"
before you see it.

hth,
Arnar

We get this problem...We ran setup_course, and we have downloaded the
checkSync tool to the same directory as our code.

Hej,  I managed to run the checkSunc tool in Eclipse. I just added the checkSync.jar as an external jar in my project. Then I ran the application with main class set as "edu.umd.cs.pugh.CheckSync" and one program argument, the "PasswordApp". And it  works. I attach a screen-shot of what I mean. /Greg Asdranias --- On Fri, 16/4/10, Mats <risk2...@gmail.com> wrote:
