Re: Xml-rpc client from Applet

[Praveen Udawat]

Hi Remis,   An applet can make network connection only with  the machine from which it is originated. It can not connect to any other machine.This is a fundamental "sandbox" issue. So the xml-rpc server to which you are connecting through applet should be on same the machine.   But if the xml-rpc server is on a different machine then you need to write a proxy server on your host machine which can forward your xmlrpc request to actual xmlrpc server.   Hope it will help you.   Praveen Udawat  ----- Original Message ----- From: remigijus To: [EMAIL PROTECTED] Sent: Thursday, November 06, 2003 7:37 AM Subject: Xml-rpc client from Applet Hi     When I'm using XmlRpcClient from the applet i getting the following message in the Sun Java Console   java.security.AccessControlException: access denied (java.util.PropertyPermission org.apache.xmlrpc.TypeFactory read)  at java.security.AccessControlContext.checkPermission(AccessControlContext.java:269)  at java.security.AccessController.checkPermission(AccessController.java:401)  at java.lang.SecurityManager.checkPermission(SecurityManager.java:524)  at java.lang.SecurityManager.checkPropertyAccess(SecurityManager.java:1276)  at java.lang.System.getProperty(System.java:573)  at org.apache.xmlrpc.XmlRpc.<init>(Unknown Source)  at org.apache.xmlrpc.XmlRpcClient$Worker.<init>(Unknown Source)  at org.apache.xmlrpc.XmlRpcClient.getWorker(Unknown Source)  at org.apache.xmlrpc.XmlRpcClient.execute(Unknown Source)  at adminApplet.CategoriesModule$GetCategoriesAction.xmlRpcGetList(Unknown Source)  at adminApplet.CategoriesModule$GetCategoriesAction.actionPerformed(Unknown Source)  at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1786)  at javax.swing.AbstractButton$ForwardActionEvents.actionPerformed(AbstractButton.java:1839)  at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:420)  at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:258)  at javax.swing.AbstractButton.doClick(AbstractButton.java:289)  at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:1113)  at javax.swing.plaf.basic.BasicMenuItemUI$MouseInputHandler.mouseReleased(BasicMenuItemUI.java:943)  at java.awt.Component.processMouseEvent(Component.java:5100)  at java.awt.Component.processEvent(Component.java:4897)  at java.awt.Container.processEvent(Container.java:1569)  at java.awt.Component.dispatchEventImpl(Component.java:3615)  at java.awt.Container.dispatchEventImpl(Container.java:1627)  at java.awt.Component.dispatchEvent(Component.java:3477)  at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:3483)  at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3198)  at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3128)  at java.awt.Container.dispatchEventImpl(Container.java:1613)  at java.awt.Component.dispatchEvent(Component.java:3477)  at java.awt.EventQueue.dispatchEvent(EventQueue.java:456)  at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:201)  at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:151)  at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:145)  at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:137)  at java.awt.EventDispatchThread.run(EventDispatchThread.java:100)     It looks like XmlRpc object is trying to access some property which is denyed by the Applet's security manager.   So is it possible to use XmlRpcClient client from the applet.   By the way, when I'm do debugging from AppletViewer evrything is Ok.   I tryed to use Client classes from Applet package but there is comments that they are pretty old.   So where is problem and how to deal with it       Remis
