Sub Tasks

Description
FULL PRODUCT VERSION :
java version "1.6.0-rc"
Java(TM) SE Runtime Environment (build 1.6.0-rc-b104)
Java HotSpot(TM) Client VM (build 1.6.0-rc-b104, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
tomcat web server version 5.5.7

A DESCRIPTION OF THE PROBLEM :
when referencing a jar resource in the jnlp file via the href reference the href reference must end in .jar for web start to download the jar.

working example:
<jar href="/ICE/Jar/commons-httpclient-3.0.jar"/>

downloads fine in jre 1.5.x and jre 1.6.x

bug example: <jar href="/ICE/Jar/commons-httpclient-3.0.jar;jsessionid=BD307F0DDCF0F9E36B9D4C16F30DF601"/>

downloads fine in jre 1.5.x  broken in jre 1.6.x

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
create a jar resource that can be downloaded from a web server with a url that does not end in .jar.
Reference this url in a jnlp file.

example: <jar href="/ICE/Jar/commons-httpclient-3.0.jar;jsessionid=BD307F0DDCF0F9E36B9D4C16F30DF601"/>

downloads fine in jre 1.5.x  broken in jre 1.6.x

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The jar file is downloaded from the url and used by the application launched via the jnlp file
ACTUAL -
The application referenced in the jnlp file does not start

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No information is displayed in the java console

REPRODUCIBILITY :
This bug can be reproduced always.

SUGGESTED FIX

http://sa.sfbay.sun.com/projects/deployment_data/dolphin/6494365.2
2006-12-04 
EVALUATION

The chosen fix was to both try trimming suffixes from the file name as well as to check the MIME type of the returned file in case it does not end in either .jar or .jarjar. Fixed in Java SE 7, we believe in build 04 (integration schedule is not available yet -- should definitely be integrated by build 06).
2006-12-04 
EVALUATION

The issue of 6497360 is similar to this one. Checking for the MIME types associated with jar files and jar diffs (suggested by ###@###.###) rather than specific file name extensions is a more robust solution to the problem.
2006-12-01 
EVALUATION

can reproduce problem now using tomcat.  jsessionid is supported by default with tomcat.

SUGGESTED FIX

http://web-east.east/deployment/www/webrevs/ngthomas/6494365/webrev/
2006-11-17 
EVALUATION

I tried with 5u9 but I cannot get the application to launch with <jar href="/ICE/Jar/commons-httpclient-3.0.jar;jsessionid=BD307F0DDCF0F9E36B9D4C16F30DF601"/>

same for 6.0.

will contact the submitter to get more information on how to reproduce the bug.
