Move a file to a shared drive in Java

Categories Information Technology, Programming

I had a bit of trouble with this, in a program I’m writing at the moment. Every time I tried to move a file to a shared folder, on my computer, it would fail. Turns out, it (apparently) because Java doesn’t necessarily share my mapped drives. Here’s the code that I used to overcome this:


System.out.println("Try to move file");

try{
// create a net use command to map the drive...
String command = "c:\\windows\\system32\\net.exe use Z: \\\\172.16.1.74\\f$";
Process p = Runtime.getRuntime().exec(command);

// create an instance of the file to move
File f=new File(".\\myImage.jpg");

// make sure that the file actually exists
boolean fileExists=f.exists();
if(fileExists){
System.out.println("File Found");
}else{
System.out.println("File Not Found");
}

//create a random number and timestamp, for a unique file name
Random rand = new Random();
int randNum = rand.nextInt();
Date date=new Date();

// Create the new filename
String newFileName=new String("myImage_"+date.getTime()+"_"+randNum+".jpg");

//try to move the file
boolean moved=f.renameTo(new File("Z:\\Home\\ITS\\sigImages\\"+newFileName));
if(moved){
System.out.println("File moved -> "+newFileName);
}else{
System.out.println("File Not moved");
}
}catch(Exception ex){
ex.printStackTrace();
};

I’m sure there is a more elegant way of doing this, that more experienced Java programmers will know. But, I could not find too much out there on the web… Hope this helps someone…

Search for non-duplicates bettween two tables.

Categories Information Technology, MySQL, PHP, Programming, Web Development

I recently had some issues trying to make sure that two columns from two different tables were the same.  After some random code writing, I came up with the following MySQL code…  Hope it helps others…

[code]
/* return from first table */
$checkTable1=@mysql_query("SELECT table1.column1 FROM table1 LEFT JOIN table2 ON table2.column2 = table1.coumn1 WHERE table2.column2 IS NULL");

/* return from second table */
$checkTable1=@mysql_query("SELECT table2.column2FROM table2 LEFT JOIN table1 ON table1.column1 = table2.column2 WHERE table1.column1 IS NULL");
[/code]

I’m sure there is a better way to accomplish it, but this worked for my needs…  Just a quick search, and then I added some extra code to update the tables if there are any discrepancies.
