No access to Filesystem in spite of all-permissions

Hi,

I've written an application and want to start it via JWS. This is my JNLP-File:

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

<jnlp spec="1.0" codebase="http://foo/" href="bar.jnlp">

<information>

<title>foo</title>

<vendor>me</vendor>

<homepage href="http://foo/" />

<description>foobar</description>

<offline-allowed />

</information>

<security>

<all-permissions />

</security>

<resources>

<j2se version="1.5+" href="http://java.sun.com/products/autodl/j2se" />

<jar href="foo.jar" main="true"/>

<jar href="comm.jar"/>

<jar href="ojdbc14_10.1.0.4.jar"/>

</resources>

<application-desc />

</jnlp>

As you can see, I've set the all-permissions-element.

The application needs to access the COM-port and an Oracle-DB, so two jars are needed. I have signed these two jars and my own with "jarsigner foo.jar myalias" and they seem to by signed correctly. Here's the output of "jarsigner -verify":

V:\htdocs\jnlp>jarsigner -verify foo.jar

jar verified.

V:\htdocs\jnlp>jarsigner -verify ojdbc14_10.1.0.4.jar

jar verified.

V:\htdocs\jnlp>jarsigner -verify comm.jar

jar verified.

But when i start my app via JSW, i get the following error:

java.io.FilePermission.init(Unknown Source)

java.io.FilePermission.<init>(Unknown Source)

java.lang.SecurityManager.checkDelete(Unknown Source)

javax.comm.CommPortIdentifier.getPortIdentifierts(CommPortIdentifiert.java:70)

...

Thanks a lot for your help in advance!

Regards,

Markus
