Any help with the issue would be appreciated. I am running windows 7 and using Java 1.7.0_13.

We had a very similar issue. I think the problem is the space in the Username. Can you move the sfx folder to just the C: drive so it doesn't have to go through the User account with the space? When you launch sfx it needs to make two other files, sfxlib.jar being one of them. I forget the name of the other. Even if the files exist already, the space in the Username is problematic for the system finding them.

We ended up making a different user account with a name without spaces and it worked just fine for opening. Although we haven't been able to get it to open with Driver Station. (http://www.chiefdelphi.com/forums/sh...93#post1327293)

I hope this helps!

(sfx dev here) hmm, thats very odd. This is the latest released build I assume? Does moving to a non-space user dir work?

Yes, we also had the same problem with being unable to launch SmartDashboard 2.0. The sfx directory had the sfx.jar file, but issuing the command "java -jar sfx.jar" resulted in an error stating that the file "sfxlib.jar" was not found.


The directory path had a directory with spaces, which was being translated by java into "%20".

Moving the sfx.jar file to a directory with no spaces allowed the sfxlib.jar and sfxmeta.jar to be created, and the SmartDashboard was launched.

Also tried moving these two files into the directory that had a space, but still received the error that the sfxlib.jar file was not found, and the directory path had "%20" as the path (instead of a space), which is probably why java was unable to find the file.

I moved it it to the C:// directory and got the error mentioned in this post.

Putting this line into the FRC DS Data Storage.ini works for me - I have to switch to Java then back to default to launch it. Also it takes a second for it to show up.

DashboardCmdLine = "C:\\apps\\jdk1.7.0_51\\bin\\java.exe -jar c:\\SFX\\sfx.jar"

Things to know:
1: I installed java to the directory above so modify accordingly
2: I copied sfx.jar and plugins to a new directory called SFX right off the root of the C: drive.
