nxjbrowse problem on ubuntu[SOLVED]

[adamkrisz]

Hi

I installed lejos 0.9.1 on my nxt. I use ubuntu 12.10 and everything works great, I can compile and run my programs, but the nxjbrowse throw IOExceptions and make 0byte files when I try download or upload with it. I have no idea what can be the problem or something, so do you have some tip?

(Sorry for my bad English)

I have fixed the problem : http://lejos.sourceforge.net/forum/viewtopic.php?f=7&t=4308&p=18643#p18643

What do these IOExceptions look like?
Is there any output on the terminal?

and only this in the terminal:

Code: Select all

krisz@krisz-ubi:~/robot$ nxjbrowse
Found NXT: NXT 00165313C000

Thanks for that. I'm afraid that is useless. But that is not your fault. I will have to prepare a special version of nxjbrowse, that isn't that shy about the details of the exception (message string, stack trace, etc.). Unfortunately, I don't have time for that right now. Can you reproduce the issue with nxjupload? Or maybe nxjcontrol? (Even though nxjcontrol might be just as quiet as nxjbrowse about the exception details.)

[adamkrisz]

nxjcontrol does the same, but nxjupload works.

[skoehler]

Do you run programs while nxjbrowse or nxjcontrol remains connected to the NXT?
Does the IOException go away, if you disconnect/reconnect in nxjcontrol before/after you run a program?

I dont run program at all (and absolute not while i try download)

So when exactly does the problem happen? Can you reproduce it by a certain procedure? Tell me exactly what you do to reproduce the problem.

hm, I'm sorry if I wasn't clear, so: I wrote a program wich make a file on the nxt. This program has run and made the file (and every other prorgam works). But the main problem is that I cant download any file (programs or the file the program made) with nxjbrowse/nxjcontrol.

I have just solved the problem: the system accidently used the open jvm, I changed it back to the oracle's jvm with 'sudo update-alternatives --config java'

Thanks for your help:)
