[kepler-dev] How to share Kepler among multiple users on one machine?

[Jianwu Wang]

Hi all,

    One of our partner has the following requirements, which I think it 
is quite common.
    They want to install Kepler on one machine only once and it can be 
shared by multiple users. So Kepler was installed by root user and it 
was started through kepler.sh command by other users. But we got the 
following exception:

regArray: org.ecoinformatics.ecogrid.registry.stub.RegistryEntryArrayType at 312ae32c
ERROR (org.ecoinformatics.seek.ecogrid.SearchRegistryAction:queryRegistryRewriteConfig:246) Problem writing new services to config file
Unable to process kar file: /home/invite/SANDIEGO/kepler/./kar/actors/ImageJ.kar

  The exception is because that the user do not the right to write the config file. 

  To make Kepler sharable by multiple users, can we divide the config file into public part and private part so that each user can read the public part from the $Kepler directory and write the private part into private file, such as in $HOME/.kepler directory?

  To go future and make actors sharable, can we also divide the config file of actors into public part and private part so that each user can use the public actors from the $Kepler directory and private actors from private file, such as in $HOME/.kepler directory? In this way, each user can make/import his/her own kar files and use the actors.
