The server reports that the JNLP client requests resources multiple times before checking jar.

It may be the wished-for resource is requested up to 10 times from the server, before finally checking and finding the it in the loaded JAR-file. My app is deployed as an applet using dtjava.embed() and a JNLP-file. The applet does start, but only after a big delay for the 100+ requests it sends to the server first!

Any ideas on what is causing the redundant requests, and how to fix it?

Answer 1

So it was actually this page which lead me to the solution: Java WebStart slow, requesting libraries from invalid folder

I didn't know about indexing of JARs at all. Now I do. And as soon as I added an index to the JAR, the problem went away!

Thank you all.
