We have a spring-enabled java desktop application started through Java Web Start.
The JNLP is properly created and downloaded but in the server http logs we see 404 errors on download on some unexisting libraries (org.springframework.core.jar and org.springframework.beans.jar):

From the timestamp gap (+/- 10s), I suspect that the download occurs when the spring context loads. But I can’t figure out why.

Any suggestion?

Edit:
It’s probably worth noting that this behavior is not a blocking issue: the app works correctly. However, the server log pretty quickly fills with 404s.

Here is the JNLP file downloaded from the server. I’m pretty confident it is ok (checked it with JaNeLA already), and it sure doesn’t include the 404’d libs.

This issue is caused by the conjunction of two things :

we use a classpath scanner in the app to auto-discover annotated
spring beans
there is a known open bug in the packaging of the published spring artifacts (https://jira.springsource.org/browse/SPR-6383)

We ended up using the simpler timestamp-based solution (after patching JBoss VFS so that the last-modified timestamp of files is not overridden at each server reboot)
