Hi,
I have had a few members of staff getting an error when using the document unpackager building block from OSCELOT.
I am not sure if it is anything to do with a change of java classes impacting on the building block but it seems to have only happened after moving to continuous deployment on Friday. I would look for changes in the documentation but I am not sure where to look now that we are on SaaS.
Are you able to advise me at all on what I can do to pinpoint the problem? The full error message is below.

Any help you could give me would be greatly appreciated.

Thanks,

Joe

Hiya Joe Currie

This is a private API, so not subject to the same protections as public ones. It appears that this one has moved:

ContentSystemServiceExFactory.getIntance().getNavigationManager().getHomeDirectory(...)

See the reply in context

  Hi Scott
  Thanks so much for getting back to me. It's all working nicely now. Is there anywhere that I can find out any of thse sorts of changes in the future? Or is it not possible due to it being a private api?

      Hi Tami Regulski,
      My apologies for not getting back to you sooner.
      
      I changed the line which gave me the problem:
      String csLocation = ContentSystemServiceExFactory.getInstance().getDocumentManagerEx().getHomeDirectory( ctx.getCourse() );
      to:
      String csLocation = ContentSystemServiceExFactory.getInstance().getNavigationManagerEx().getHomeDirectory( ctx.getCourse() );
      Once i uploaded the B2 back into Blackboard it started working as it should have done originally.
      
      I hope that helps.
      Thanks,
      Joe

        I just used notepad++.
        As i had the original B2, i unpackaged it into a folder then opened the file i had problems with in notepad++. After i made the change and saved it, I zipped the files back up then uploaded the updated building block.

        Great, I was hoping you would say that but you mention "unpackaging" it
        into a folder. Everytime I open the .war in Notepad ++ it is encoded and I
        can't get it to english. So I was hoping I could do it but now think maybe
        I can't without more help.

        I use 7-zip which lets you open up .war files. Once installed, you just need to right click on the war file then under the 7-zip options "choose unpackage to" and choose the location. This will put all the files where you can open them individually.
        If you still have problems, let me know and I can do a quick video for you once I'm back in the office tomorrow.

        It's me again. Now I'm at a loss of how to re-create the .war file. 7 Zip
        doesn't allow for me to package all of that back up into a .war file.

        Just using 7-zip to package it all back up to install it sounded much to good to be true and it was. This didn't work. It gives an error stating that "No manifest file was found in Web-inf when the manifest file is there in that folder. I also found "DocumentManager" in several places in the Building Block how it is that only changing it in the one place and using 7-zip to just re-zip it up after you edited the code made this building block work for you. I'm at a loss really.

        I have had similar issues before which were because of zipping the folder rather than all the files (zipping a level to high). Could you send me the original B2 and I can try making the changes for you and zip it up? I'll do a wee video of how I do it too if that would be helpful. I wouldn't be able to test it myself though as I am on a SaaS deployment, but can send you the zip file back.

      Hi Joe,
      
      The Building Block upload will take a .zip. What I found I was doing was
      zipping it up at the wrong level in the folder hierarchy. The first time I
      tried, I zipped the folder "DocUnpackager", when instead I should have gone
      inside of that folder, selected the 6 items there and .zipped that. I've
      since done this and have been able to upload the Building Block. I hope
      this helps.

        I have none. This is the same point I am at right now as well. I had to
        stop working on this earlier this summer and your inquiry prompted me to
        look at it again. I am at this exact point except I removed the 'Ex' in
        "GetNavigationManagerEx" because the first reply to this discussion did not
        have the Ex in their response. However, a second error in line 164 has now
        come up and I am trying to find a way to fix that one.

        Hi Tami,
        
        Unfortunately I'm not down under. I'm in Scotland so it's about -7 but no snow. Want to swap?
        
        I tried emailing it to you but your institution blocked it. Probably because of the zip file. But I have put it into GoogleDrive instead and can be found at the link below. Which would be handy for anyone else wanting to use it too.
