[opencms-dev] Error loading existing htdocs.tgz as module

[Thomas Gagné]

I loaded the .tgz file into WEB-INF/export/modules and it showed-up in 
the "Upload from System" dialog.  After selecting the file I get this 
traceback.  I had read that I should be able to tar/zip an existing 
directory structure and OpenCMS should be able to suck it in.  Is this 
not true?  Does it not understand .tar formats?
