Answer 1

FileUtils is not part of the standard JDK, it a class in the Apache Commons IO library.It contains Methods like
FileUtils.readFileToString(file);
FileUtils.copyDirectoryToDirectory(source, destination);
FileUtils.deleteDirectory(source);......................which make copying files from one directory to other directory in most easier way in word it reduces voluminous amount of code as entire code is written by Apache people

Answer 2

<s:file id="myFile" name="myFile" disabled="true" ></s:file> is the tag that is used to upload file put the tag in jsp.
And the properties in action class as i written below
private File myFile;
private String myFileContentType;
private String myFileFileName;
/**
* #return the myFile
*/
public File getMyFile() {
return myFile;
}
/**
* #return the myFileContentType
*/
public String getMyFileContentType() {
return myFileContentType;
}
/**
* #return the myFileFileName
*/
public String getMyFileFileName() {
return myFileFileName;
}
/**
* #param myFile the myFile to set
*/
public void setMyFile(File myFile) {
this.myFile = myFile;
}
/**
* #param myFileContentType the myFileContentType to set
*/
public void setMyFileContentType(String myFileContentType) {
this.myFileContentType = myFileContentType;
}
/**
* #param myFileFileName the myFileFileName to set
*/
public void setMyFileFileName(String myFileFileName) {
this.myFileFileName = myFileFileName;
}
and In execute method insert this code
String destaddress=getText("ipaddress");
if(myFile!=null){
File destDir= new File(destaddress+myFileFileName);
destDir.createNewFile();
FileUtils.copyFile(myFile, destDir);
}
you add ip address in apllication properties file as show below
ipaddress=\\\\192.168.105.68\\Shared2\\Files\\
and the following interceptors to your struts. XML file
<interceptor-ref name="fileUpload">
<param name="maximumSize">52428800</param>
</interceptor-ref>
<interceptor-ref name="basicStack"/>
ipaddress=\\\\192.168.105.68\\Shared2\\Files\\
This will solve your problem.
