Sure, I can help you with a sample JCN code to unzip a file. Here's an example:
| Code: |
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
import com.jcn.client.JCN;
public class UnzipFile {
public static void main(String[] args) throws IOException {
JCN jcn = new JCN();
// Connect to the queue
jcn.connect("your-queue-name", "your-queue-password");
// Get the message from the queue
String message = jcn.getMessage();
// Get the zip file as a byte array
byte[] zipFileBytes = message.getBytes();
// Create a new ZipInputStream
ZipInputStream zis = new ZipInputStream(new ByteArrayInputStream(zipFileBytes));
// Loop through all the entries in the zip file
ZipEntry zipEntry = zis.getNextEntry();
while (zipEntry != null) {
// Get the file name
String fileName = zipEntry.getName();
// Create a new file with the same name
File newFile = new File(fileName);
// Create the file's parent directories if they don't exist
if (!newFile.getParentFile().exists()) {
newFile.getParentFile().mkdirs();
}
// Create a new FileOutputStream
FileOutputStream fos = new FileOutputStream(newFile);
// Read from the ZipInputStream and write to the FileOutputStream
byte[] buffer = new byte[1024];
int len;
while ((len = zis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
// Close the FileOutputStream
fos.close();
// Get the next entry in the zip file
zipEntry = zis.getNextEntry();
}
// Close the ZipInputStream
zis.close();
// Disconnect from the queue
jcn.disconnect();
}
} |
This code uses the JCN client library to connect to a queue, get a message, and then unzip the contents of the message. You'll need to replace "your-queue-name" and "your-queue-password" with the actual name and password of your queue. |
