Subject UnauthorizedAccessException error while running WMI in tomcat
Date Tue, 02 Sep 2008 06:13:55 GMT

I have written the following code in Java to access registry of a remote
machine. I am able to execute the program successfully when i run the
program separately. But when I try to execute the code in Apache Tomcat. I
am getting 
UnauthorizedAccessException error.The full text of error is
System.UnauthorizedAccessException: Access to the registry key is denied. at
Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) at
Microsoft.Win32.RegistryKey.OpenRemoteBaseKey(RegistryHive hKey, String
machineName) at BOMInfoCollector.BOMInfoCollector.getOSVersion(StreamWriter
file, String remoteName) 
Following is the Java code: try { String keykey =
String ipadddress = Remote machine's IP; String keyStr1= keykey + " " +
Process p = Runtime.getRuntime().exec(keyStr1); 
BufferedReader stdInput = new BufferedReader(new
BufferedReader stdError = new BufferedReader(new
// read the output from the command 
while ((s = stdInput.readLine()) != null) 

response = response + s +"\n"; 
while ((s = stdError.readLine()) != null) 
response = response + s +"\n"; 
}}catch(Exception e){ 
System.out.println("Exception occured "+e); 

Following is the C# code whose name is 
string osKeyName = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion"; 
RegistryKey hklm = RegistryKey.OpenRemoteBaseKey( 
RegistryHive.LocalMachine, remoteName); 
RegistryKey osKey = hklm.OpenSubKey(osKeyName); 

if(osKey != null) { 
object prodName = osKey.GetValue("ProductName"); 
Console.WriteLine("OSName=" + prodName); 
Console.WriteLine("Exiting getOSVersion() method"); 
}catch(System.UnauthorizedAccessException e){ 
Console.WriteLine("You are not authorized to access the machine.Please check
the network Privileges "+e); 
}catch(Exception e){ 
Console.WriteLine("Error occured "+e); 
} Please let me know what can be the possible problem.
