Getting Action Mapping in JSP

One can use "org.apache.struts.action.mapping.instance" to get the action mapping in JSP:

import org.apache.struts.config.ActionConfig;
ActionConfig mapping = (ActionConfig)request.getAttribute("org.apache.struts.action.mapping.instance");

Form name will be mapping.getName()

To activate a window using VBS

set oShell = WScript.CreateObject("WScript.Shell")
call oShell.AppActivate(<Window's Title>)

Copy files from tsclient

For example:

xcopy \\TSCLIENT\F\$Update\ *.* "C:\Documents and Settings\%USERNAME%\My Documents\" /s /v /f

Enable/Disable network interface via command line

c:\> netsh interface set interface "INTERFACE_NAME" enable

OR

c:\> netsh interface set interface "INTERFACE_NAME"disable

Reading and saving UTF8 text file in Java

To read and save text file in Java, we need to add the "UTF-8" parameter in the Stream Reader.


File file = new File("1.txt");
BufferedReader reader = null;
try {
   reader = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8"));
   String text = reader.readLine();
   String s1="\u6df1\u6c34\u57d7";
   String s2="深水埗";

   OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream("2.txt"),"UTF-8");
   out.write(text+s1+s2);
   out.flush();
   out.close();

} catch (Exception e) {
   e.printStackTrace();
}


Capture standard output (stdout) in console command running at VBS

We can use WScript.Shell.Exec( ) and WScript.Shell.StdOut.ReadLine( ) to perform the task:


Set objShell = WScript.CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("cmd /c dir")
strText=""
Do While Not objExecObject.StdOut.AtEndOfStream
strText = strText & objExecObject.StdOut.ReadLine() & chr(13)
Loop
Wscript.Echo strText
