New Revision: 1725150
URL: http://svn.apache.org/viewvc?rev=1725150&view=rev
Log:
Small code improvements in HostConfig class:
1) In deployWAR() call digester.reset() first before doing non-trivial work
such as "new URL(...)",
because digester is a shared instance. Though a failure in the "new URL()" call
there is very unlikely.
2) Reduce scope of "JarEntry entry" variable, getting rid of
"finally{entry=null;}" blocks.
Anyway a JarEntry is available only while the original JarFile is open.
