Hi! I have a problem. I am involved in designing an Upload Utility which will pick files after they arrive in the UNIX box and load the same into the database. For this, I need to create a dependency tree for the files, and schedule the processing accordingly. Can anyone provide the necessary information on how to go about doing this? For example, I have that file A depends on files B and C. B and D both depend on D and D depends on nothing. As such, for A, I have D, then B and C and then only A. Here a tricky situation is when B fails. Then I should be able to process C, which in no way depends on B. Anyone has any idea on algorithms in Java Collections to use in order to do this?    More>>
