After we download and unzip the jaxp1.1 zip file, the owner himself faces permission problems. On unzipping, the directory jaxp-1.1ea2 is created and it doesn't have execute permission for the owner. And all the subdirectories has the same problem. He won't be able to run "cd" command also.
To get around of this problem, the owner has to do a
"chmod -R +x jaxp-1.1ea2" as a must. Otherwise he can't proceed with anything.
