Hi All, I am trying to run a client application over webstart, where the application uses HttpClient to get data from the server where it was downloaded. But the access attempt results in the following errors below.
Note: HttpClient2 is my main class. The jar file run's locally. Only fails when downloaded from the server with Web Start. _________________________________________________________________________ java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.javaws.Launcher.executeApplication(Unknown Source) at com.sun.javaws.Launcher.executeMainClass(Unknown Source) at com.sun.javaws.Launcher.continueLaunch(Unknown Source) at com.sun.javaws.Launcher.handleApplicationDesc(Unknown Source) at com.sun.javaws.Launcher.handleLaunchFile(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.ExceptionInInitializerError at org.apache.commons.httpclient.HttpClient.<clinit>(Unknown Source) at test.HttpClient2.<init>(HttpClient2.java:25) at test.HttpClient2.main(HttpClient2.java:17) ... 11 more Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission org.apache.commons.logging.LogFactory.HashtableImpl read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPropertyAccess(Unknown Source) at java.lang.System.getProperty(Unknown Source) at org.apache.commons.logging.LogFactory.createFactoryStore(LogFactory.java:320) at org.apache.commons.logging.LogFactory.<clinit>(LogFactory.java:1725) ... 14 more _________________________________________________________________________ Q1.Are these security errors or 'Unknown Source' errors. I have a jar file created with Jar-Fat from eclipse. The jar can be started locally with 'java -jar Http2.jar' so it must contain all its own source code. I also tested a home-made jar to be included inside my main jar and that was found. So I am thinking it is a security problem...... Q1. The jar file is unsigned but according to Web-Start white paper from Sun the jarfile should be allowed to "Use the network to access the host from which the application was downloaded", which I am trying to do. Also, the error accurs even when I only create an instance of HttpClient ( new HttpClient() ) without making any connections to the server. Is this normal for HttpClient constructor to generate such an error? This leads me back to thinking the source is not found.... I am hoping to be able to keep the application unsigned although my next step would be to try that and see what happens. I have tried google and google-groups plus made many differnt tests. But I am coming up blank at the moment so any pointers are help would be much appreciated. Thanks for any help in advance.
