For Java Web Start to be able to run scripts (using 1.5b4b), jars have to be signed and special permissions requested in the .jnlp file which describes the Java Web Start application.
For applets, you'll have to do something similar. You can get information about how to do this, for example:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1215-security_p.html
I hope this helps,
Regards,
Vincent.

Hello Vincent, you're absolutely right (trace follows)!does it mean I have to modify a java.policy or security file on the client ? if so, how ?

There must be, bacause I'm able to use the batik "demoApplet", and view svg files containing <script> This demo applet uses the "java web start" but I believe the security constraints should be the same as for a "simple applet". regards, Christophe. trace is : java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader) at java.security.AccessControlContext.checkPermission(AccessControlContext.java :267) at java.security.AccessController.checkPermission(AccessController.java:394) at java.lang.SecurityManager.checkPermission(SecurityManager.java:540) at java.lang.SecurityManager.checkCreateClassLoader(SecurityManager.java:605) at java.lang.ClassLoader.<init>(ClassLoader.java:231) at java.security.SecureClassLoader.<init>(SecureClassLoader.java:74) at java.net.URLClassLoader.<init>(URLClassLoader.java:108) at org.apache.batik.script.rhino.RhinoClassLoader.<init>(Unknown Source) at org.apache.batik.script.rhino.RhinoInterpreter.<init>(Unknown Source) at org.apache.batik.script.rhino.RhinoInterpreterFactory.createInterpreter(Unkn own Source) at org.apache.batik.script.InterpreterPool.createInterpreter(Unknown Source) at org.apache.batik.bridge.BridgeContext.getInterpreter(Unknown Source) at org.apache.batik.bridge.BaseScriptingEnvironment.loadScripts(Unknown Source) at org.apache.batik.bridge.UpdateManager.dispatchSVGLoadEvent(Unknown Source) at org.apache.batik.swing.svg.SVGLoadEventDispatcher.run(Unknown Source) -----Message d'origine----- De : Vincent Hardy [mailto:vincent.hardy@;sun.com] Envoye : jeudi 24 octobre 2002 10:48 A : Batik Users Objet : Re: script - unknown language text/ecmascript Hello Christophe, Did you try to run your applet with applet viewer and see what trace you get. I suspect you are running into security exceptions when running under the applet's security manager. Regards, Vincent.
