Note that the explosion will not occur if the Host is
configured
so that .WARs are not exploded with a unpackWARs
attribute set to "false" to appBase which is usually webapps,
the web application
will be simply redeployed as a compressed archive.
n
unpackWARs
Should we unpack WAR files when auto-deploying applications in the
appBase directory?

Subject: different behavior in processing jar files in Tomcat 5.0.28 and Tomcat
6.0.18
Hi,
In the process of migrating an application from Tomcat 5.0.28 to Tomcat 6.0.18,
I’ve identified a different behavior in processing jar files between the two
versions. I’ve attached a small test application (testapp.war) that can be run
under both versions
to display the differences. I’ve also included the appropriate lines from the
log files of the two versions below.
Essentially, when running my Java code which calls method getResource(String
name) of class Class to find a resource that is part of a jar file, Tomcat
5.0.28 finds the jar file in the classpath and expands it in directory
jakarta-tomcat-5.0.28/work/Catalina/localhost/testapp/loader.
And then I can access the resource in the expanded jar file by calling the
getPath() method on the instance of the URL class returned by the
getResource(String name) method.
However, when running the same code with Tomcat 6.0.18, Tomcat finds the
resource in the jar file, but it does not expand the jar file under the
apache-tomcat-6.0.18/work/Catalina/localhost directory tree and therefore, I
cannot access the resource from
the jar file.
I’ve checked the Servlet Specification Version 2.4 (Tomcat 5) and Version 2.5
(Tomcat 6) to see if this should be the expected behavior under Tomcat 6, but
as far as I can tell, it should process jar files in the same was as Tomcat 5.
If anyone can let me know what the correct behavior should be for Tomcat 6, and
if there is a way that I can force Tomcat 6 to process jar files in the same
way as Tomcat 5, I would greatly appreciate it.
Thanks,
Pat
