my project deploy under weblogic11,and when i run hbase mapreduce，it throws a
NullPointerException.i found the method TableMapReduceUtil.findContainingJar()
returns null,so i debug it, url.getProtocol() return "zip",but the file is a
jar file,so the if condition:
if ("jar".equals(url.getProtocol())) cann't run. so i add a if condition to
judge "zip" type
was:

by respective the hbase source code under weblogic,we found
TableMapReduceUtil.findOrCreateJar returned string is null.because under tomcat
,jar file's protocol is jar type, but under weblogic ,jar file's protocol is
zip type,and the findOrCreateJar method cann't resolve zip type, so we should
join zip type judgement
> weblogic deployment project implementation under the mapreduce hbase reported
> a NullPointerException
