I am trying to achieve the following wmic command using j-interop.
wmic /NODE:192.168.0.195 /USER:Test /PASSWORD:password123 process call create "calc.exe"
I have my code written like this in my method. I have two other methods that create a session and connect to the WMI service so that part is taken care of.
public void wmiExecute() throws JIException {
// Obtain Win32_Process and narrow it as IJIDispatch
Object[] params = new Object[] {
new JIString("Win32_Process"),
new Integer(0),
JIVariant.OPTIONAL_PARAM()
};
JIVariant[] servicesSet = this._wbemServices.callMethodA("InstancesOf", params);
IJIDispatch wbemObjectSet = (IJIDispatch) JIObjectFactory.narrowObject(servicesSet[0].getObjectAsComObject());
params = new Object[] {
"calc.exe",
JIVariant.OPTIONAL_PARAM(),
JIVariant.OPTIONAL_PARAM(),
new Integer(0),
};
wbemObjectSet.callMethodA("Create", params);
}
I kept getting an Exception of
Caught Throwable: org.jinterop.dcom.common.JIException: Unknown name. [0x80020006]
org.jinterop.dcom.common.JIException: Unknown name. [0x80020006]
Any idea what could be wrong? Thanks in advance!
Here's the solution...
You shouldn't use InstanceOf to obtain Win32_Process because you will be just getting a list of currently running processes. Instead you should use "Get" to obtain the default Win32_Process.
public void wmiExecute() throws JIException {
// Obtain Win32_Process and narrow it as IJIDispatch
Object[] params = new Object[] {
new JIString("Win32_Process"),
JIVariant.OPTIONAL_PARAM(),
JIVariant.OPTIONAL_PARAM()
};
// Obtain the default Win32_Process
JIVariant[] service = this._wbemServices.callMethodA("Get", params);
// Convert it to a IJIDispatch object
IJIDispatch wbemObject = (IJIDispatch) JIObjectFactory.narrowObject(service[0].getObjectAsComObject());
// Create input params
Object[] paramsCalc = new Object[] {
new JIString("calc.exe"),
JIVariant.OPTIONAL_PARAM(),
JIVariant.OPTIONAL_PARAM()
};
// Create the calculator process
JIVariant[] results = wbemObject.callMethodA("Create", paramsCalc);
}
