Bug report for the jnlp servlet
There is an error in the jnlp download servlet in the version based download
mode.
I have completed the example that is used in the document "Packaging JNLP
Applications in a Web Archive" - the version based part.
I have installed jakarta-tomcat-3.2.3 and javaws-1_0_1_01-win-int.exe.
I installed the web application with as application1 in tomcat.
When I browse to http://localhost:8080/application1/app/launch.jnlp I get HTTP
404 - File not found in internet explorer.
The jnlp servlet log jnlpdownloadservlet.log says:
JnlpDownloadServlet(3): Request: /application1/app/launch.jnlp
JnlpDownloadServlet(3): User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
JnlpDownloadServlet(4): DownloadRequest[path=/launch.jnlpisPlatformRequest=false]
JnlpDownloadServlet(4): Basic Protocol lookup
JnlpDownloadServlet(3): Error code returned for request: /application1/app/launch.jnlp
JnlpDownloadServlet(4): Response:
com.sun.javaws.servlet.DownloadResponse$NotFoundResponse
I suspect that the servlet has removed app/ from the path before looking for
the launch file.
The conclusion is that the jnlp download servlet can only deliver files from
the top level of a web application.
The servlet works fine, however, in non version based download mode, and finds
the launch file in app/.
---------- here is my example:
I have added the missing main-class to the application-desc element in the jnlp file.
