cvs commit: jakarta-tomcat-4.1/catalina/src/share/org/apache/naming/resources WARDirContext.java LocalStrings.properties
remm 01/01/20 10:54:36
Modified: catalina/src/share/org/apache/naming/resources
LocalStrings.properties
Added: catalina/src/share/org/apache/naming/resources
WARDirContext.java
Log:
- Add a new WARDirContext.
- Enables to run web applications directly from a WAR file
(without unpacking).
- Will not be compatible with any servlets who want to directly read
files from the filesystem. Jasper falls into that category.
