can access jregex1.2_01-src.jar

[Nobody/Anonymous]

When I try to extract files from jregex1.2_01-src.jar by typing "jar -xvf jregex1.2_01-src.jar" at the command line, I get:

   created: META-INF/
  inflated: META-INF/MANIFEST.MF
java.io.FileNotFoundException: META-INF/MANIFEST.MF: No such file or directory

When I type "jar -t jregex1.2_01-src.jar" at the command line, I get:

What can't I get to these files?

Stupid Eli. I didn't have write permission on the containing directory. Sorry to bother you all.
