Re: [ptp-dev] Proper use of IRemoteConnection.setWorkingDirectory()

Brian,

I would be glad to present my work! Thank you for asking! I'll get in touch with Jay and CC you to set it up.

Thanks for attending my talk. I am glad you enjoyed it.

Thanks,
Jay

Hey Jay,

Would you be interested in presenting your work to the PTP user and/or developer community on one of our conference calls? I saw your presentation at EclipseCon and I think it would be good to tell us more about your work. If so, Jay Alameda <jalameda@xxxxxxxxxxxxxxxxx> in our community organizes the calls, and we always looking for good presentations like yours.

I got it working! The problem was a bug on my side that was pointing to a path that was not absolute... but of course I was 100% sure it was absolute. 

Our product logs into a remote machine, creates a time-stamped directory in the user's home directory, moves into that directory and does some work. Here's what I used to set the working directory that works for me (pretty much the same as yours above):

String currentWd = connection.getWorkingDirectory();
connection.setWorkingDirectory(currentWd + connection
.getProperty(IRemoteConnection.FILE_SEPARATOR_PROPERTY) + workingDirectoryName);

The variable "workingDirectoryName" is relative to the working directory set at login, normally /home/user.

Thanks again for your help! Looks like everything is working PTP and I'll be able to eliminate about 1000 lines of code and as many headaches. ;)

Jay

    Yes, open the connection first. You might want to check isOpen() to make sure it connected.

      Greg,

      Thanks. I will try it again. I assume you set the working directory after the connection was opened?

        Jay,

        I just tried:

        connection.setWorkingDirectory("/tmp");
        String wd = connection.getWorkingDirectory();
        System.out.println("wd = " + wd);

        and it prints:

        wd = /tmp

        So I'm not sure what is going wrong. In fact, looking at the code, the only way this would not work is if the path is not absolute.

The JavaDoc says that the path specified needs to be absolute and valid, so I am sending the name of a previously created (~6months back) directory called, for example, /home/jay/scratch. However, calling IRemoteConnection.getWorkingDirectory() always returns the original working directory, in this case /home/jay.
