Hello Paul
yes, i discovered that the base error looks like:
org.apache.ws.security.WSSecurityException: An unsupported signature or encryption algorithm was used (unsupported key transport encryption algorithm: No such algorithm: http://www.w3.org/2001/04/xmlenc#rsa-1_5)
that gave me a clue about what to search on the internet about.
what i found out was this link
http://www.mail-archive.com/wss4j-dev@ws.apache.org/msg01973.html
but unfortunatelly did not solve the problem.
1)I must mention that i uninstalled all jre and jdk from my computer, and now i have only jdk 1.6.0_11
2)i edited the java.security file to register security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider
3)replaced local_policy.jar and US_export_policy.jar in $JAVA_HOME\jre\lib\security with unlimited strength policy files from
http://java.sun.com/javase/downloads/index.jsp#docs (At the end of the page).
4)and i included in my jnlp this line <jar href="lib/bcprov-jdk16-141.jar"/>
5)and of course downloaded the this jar from
http://www.bouncycastle.org/latest_releases.html
the web start is succesfully downloading the application (i am
testing it now on local machine) just that the error above still remains. And i am again in the "don't know what to do" phase :P
thank you
