New Revision: 690453
URL: http://svn.apache.org/viewvc?rev=690453&view=rev
Log:
Copy of Mapper, with File instead of JNDI.
Ideally Mapper should extend this and override few methods - will do this if
the file is accepted to the
main branch.
( JNDI is not available on some platforms - android for example )
Added:
tomcat/sandbox/tomcat-lite/tomcat-coyote/org/apache/tomcat/util/http/mapper/SimpleMapper.java
