UnauthorizedAccessException error while running WMI in tomcat
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 =
"C:\\Diagnostic\\DiagnosticAssayRE\\Executable\\BOMInfoCollector.exe";
String ipadddress = Remote machine's IP; String keyStr1= keykey + " " +
ipadddress;
Process p = Runtime.getRuntime().exec(keyStr1);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
while ((s = stdInput.readLine()) != null)
{
response = response + s +"\n";
}
while ((s = stdError.readLine()) != null)
{
response = response + s +"\n";
System.out.println(s);
}}catch(Exception e){
System.out.println("Exception occured "+e);
}
Following is the C# code whose name is
string osKeyName = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion";
try{
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 if any configuration is needed in Tomcat to support this?

Re: UnauthorizedAccessException error while running WMI in tomcat
Posted by new_bie_tomcat <sw...@cisco.com>.
hi..
Thanks a lot for your reply. I am not able to figure out exactly where in
Tomcat i need to provide the priviledge.I have logged in to the machine with
the same login id as the remote machine. In the Tomcat logon tab i have
mentioned the same login id and password. But still i am getting the same
errror.Please let me know what changes are needed to be done in tomcat.
How can i turn off, or on the WMI priviledges?
Thanks.

Its Just a user permission thing... you starting a process in the name of
System
(See Tomcat service settings)
and that users doesnt have permission to Access WMI...
WMI priviledges can be turned off, or on...
If you run Tomcat from the BAT file... it will probably work...
Solution, use a user in the service that has permission to run WMI...
Interesting way you using for inter-app comms ;)
Sort of a Micro-Perl ;)
Have fun...

Hi,
Since you're in the domain and if my memory serves correctly (it's been a while since I worked w/ windows domains), you'll need to have proper access rights to access the registry. Not all WMI commands will work with User/Power User rights. You'll need full Administrator's rights on the target system if you want to use WMI to it's fullest. You may want to check your domain policy and the local systems' policy (if any is defined). Logging into a machine does not mean that account have the appropriate access rights, especially if you're trying access HKLM, HKCR, and HKUSERS. You may want to look into impersonation to lessen the security risk of unwanted full domain access ;)
Regards,
Tommy

Hi Mark,
Thanks a lot for your reply. I am not able to find out exactly where to
change the permission. I am using Tomcat 5.5. I have logged in to the
machine, using the same user login as the remote machine. Both of the
machine are in the same domain. In tomcat Properties Log on Tab i have
logged in as the same login ID of the local/ remote machine. But still i am
getting the same error.Please let me know where exactly i need to configure
properly.
Thanks again..

You need to run Tomcat under a user that has the permissions to perform
the action you are trying to perform. If you are running Tomcat as a
service, the default LocalSystem user will not have this permission.

Thanks for your reply.You are absolutely right. This error is a .NET
Exception.I am not able to figure out exactly where in Tomcat i need to
provide the priviledge.I have logged in to the machine with the same login
id as the remote machine. In the Tomcat logon tab i have mentioned the same
login id and password. But still i am getting the same errror.Please let me
