I’'m developing a chat applet for the browser. I use wildfire 3.0 and smack* 2.2.1
The chat applet is included into the html file with
</APPLET
When I try to start the load the page containging this applet, the initialization crashed due to
java.security.AccessControlException: access denied (java.util.PropertyPermission java.home read)[/b]
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:26 4)
at java.security.AccessController.checkPermission(AccessController.java:427)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
at java.lang.SecurityManager.checkPropertyAccess(SecurityManager.java:1285)
at java.lang.System.getProperty(System.java:627)
at org.jivesoftware.smack.ConnectionConfiguration.(XMPPConnection.java:164)
at com.applet.jabber.ChatClient.connect(New10Client.java:98)
According to
http://java.sun.com/docs/books/tutorial/deployment/applet/properties.html
(see bottom) no browser let applets read the system property “java.home”.[/b]
Does there exist a workaround?

Hi,
may one ask why you need java.home in your applet? It may be a good idea to change the applet that it does not try to get this value.

I do not need java home!
XMPPConnection con = new XMPPConnection(server,port);
seams to needs java.home in order to get some certificates

see also: (smack: org.jivesoftware.smack.ConnectionConfiguration) (called by XMPPConnection)
public ConnectionConfiguration(String host, int port, String serviceName) {
this.host = host;
this.port = port;
this.serviceName = serviceName;
// Build the default path to the cacert truststore file. By default we are
// going to use the file located in $JREHOME/lib/security/cacerts.
String javaHome = System.getProperty(“java.home”);
StringBuffer buffer = new StringBuffer();
buffer.append(javaHome).append(File.separator).append(“lib”);
buffer.append(File.separator).append(“security”);
buffer.append(File.separator).append(“cacerts”);
truststorePath = buffer.toString();
// Set the default store type
truststoreType = “jks”;
// Set the default password of the cacert file that is “changeit”
truststorePassword = “changeit”;
}
Problem solved by signing the applet
