Java Web Start applet - native library fails to load on second try -

-

i have applet loaded via java web start in browser. applet uses few native libraries things microsoft office interop , active directory communication.

here's jnlp:

<?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.5+">     <information>         <title>my applet</title>         <vendor>my vendor</vendor>     </information>     <security>       <all-permissions/>     </security>     <resources os="windows">         <!-- application resources -->         <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" />         <jar href="applets/myapplet.jar" main="true" />         <nativelib href="applets/jacob.jar"/>         <nativelib href="applets/com4j.jar"/>     </resources>     <applet-desc           name="my applet"          main-class="com.applet.myapplet"          width="770"          height="825">      </applet-desc> </jnlp>

when applet loaded, fine , libraries work expected. however, if close applet , re-open it, error in java console:

unsatisfiedlinkerror: no jacob in java.library.path unsatisfiedlinkerror: no com4j in java.library.path

if clear java cache, begins working again. however, works 1 more time, after fails same error until clear java cache again.
