Webstart: service.installSucceeded(false) becomes endless loop
Hi at all !
I have a problem implementing an installer for webstart. The installation of my program is ok but if i want to finish the installer with service.installSucceeded(false); i think i get a endless loop and the WS says that there was a JNLPException: Launch File Error.
Here my jnlp file:
<?xml version="1.0" encoding="utf-8"?>
<!-- JNLP File for JVision Application -->
<jnlp
spec="1.0+"
codebase="http://myhost/mydir"
href="jai.jnlp">

<jar href="test.jar"/>
<property name="url.to.file" value="http://myhost/mydir/exe_file_that_should_be_installed.exe"/>
<property name="destination.file.name" value="exe_file_that_should_be_installed.exe"/>

<property name="install.type" value="NATIVE_EXE_INSTALLATION"/>
</resources>
<installer-desc main-class="myself.webstart.Installer"/>
</jnlp>
And here the installer i wrote:

Anyone any idea where my mistake could be ?
