1.XML encoding not known, but declared as UTF-8

  1. Optimize this application for off-line use by adding the flag.

  2. Downloads can be optimized by specifying a resource size for 'WithoutManifest.jar'.

  3. The resource download at WithoutManifest.jar can be optimized by removing the (default) value of download='eager'.

5.The resource download at WithoutManifest.jar can be optimized by removing the (default) value of main='false'.

  1. It might be possible to optimize the start-up of the app. by specifying download='lazy' for the WithoutManifest.jar resource.

  2. Lazy downloads might not work as expected for WithoutManifest.jar unless the download 'part' is specified.

  3. Downloads can be optimized by specifying a resource size for 'pic.gif'. Icon loading & use can be optimized by specifying the width and height for pic.gif

  4. The HREF of 'http://localhost:8080/' could be optimized to ''.

<?xml version="1.0" encoding="UTF-8"?>

          <jar href="WithoutManifest.jar" />
     </resources>

     <application-desc main-class="WithoutManifest" />
</jnlp>

I am only seeing below two Pop-up before my actual application.

Also how can i change the below values selected in RED, i am not providing those anywhere in .jnlp file

Apache version -8.0.23 Java version - 1.8.0_40-b26

The splash screen will not appear on first launch. The priority for the first launch is to get the classes downloaded and cached, and the app. on-screen.
