# JavascriptProbe- Global

The JavascriptProbe script include provides methods for using the JavascriptProbe on the MID Server.

Use these methods in server scripts to send a probe to the MID Server For more information, see [Create a JavaScript Probe activity](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/servicenow-platform/t_CreateAJavaScriptProbeActivity.md).

## JavascriptProbe - JavascriptProbe\(String midServer\)

Creates an instance of the JavascriptProbe.

|Name|Type|Description|
|----|----|-----------|
|midServer|String|The MID server name|

The following example shows how to use an instance of JavascriptProbe.

```
var jspr = new JavascriptProbe('midserver_name');

var func = function () {
    // Java FileWriter class of java.io package. FileWriter is write data in character.
    var FileWriter = Packages.java.io.FileWriter;

    // Constructs a FileWriter object given a file name.
    var file = new FileWriter("TestMessage.txt");

    // Gets the parameter from the ECC queue payload.
    var message = probe.getParameter("message");

    // Write the message to a file.
    file.write(message);

    // Close the FileWriter.
    file.close();
    file = null;
}

// Add parameter to pass to MIDServer.
jspr.addParameter('message', 'ServiceNow Message');

// Set the script to be executed by the MIDServer as a string
jspr.setJavascript('(' + func.toString() + ')();');

// Send to MIDServer. The MIDServer will execute the Script immediately.
jspr.create();
```
