Multiple HTTP GET requests for individual classes
I have a Java plug-in deployed under tomcat 6. JRE version is 1.6.0_16. All the required jars are deployed packed (pack.gz) and the applet tag has 'java_arguments' parameter defined as:
All the jars get loaded nicely as I see in the Tomcat access log:
127.0.0.1 - - [03/Mar/2010:17:24:04 +0000] "GET /testapplet/lib/log4j-1.2.13.jar.pack.gz?version-id=1.2.13 HTTP/1.1" 200 0
but immediately I see a bunch of GET requests for the individual classes in the same log4j jar:
127.0.0.1 - - [03/Mar/2010:17:24:06 +0000] "GET /testapplet/lib/org/apache/log4j/Logger.class HTTP/1.1" 404 0
127.0.0.1 - - [03/Mar/2010:17:24:06 +0000] "GET /testapplet/lib/org/apache/log4j/Category.class HTTP/1.1" 404 0
127.0.0.1 - - [03/Mar/2010:17:24:06 +0000] "GET /testapplet/lib/org/apache/log4j/spi/AppenderAttachable.class HTTP/1.1" 404 0
As you can see each of these GET requests are returned a Http error code 404. While testing locally, this isn't adding any delays, but over a real deployment it's bound to be slow down the applet loading while the server is responding to each of these class requests.
Subsequently, the application itself runs without any issues and these bogus class requests failures have no effect (thankfully) on the functionality.
Any one seen this behavior? Appreciate any thoughts or help.
