Hi sudeepm,
Use Java FileWriter APIs, though I don't understand why you are reinventing the wheel and not using the file extender nodes...
Regards. |

we are using extender as it has some issues related to performance
I am using this way..evn though it works. i just want to know is this the only way to do.
private void writeToFile (String text)throws IOException{
Writer output = null;
File file = new File("C:/write.txt");
output = new BufferedWriter(new FileWriter(file,true));
output.write(text);
output.write('\n');
// writer.newLine();
output.close();
System.out.println("Your file has been written");
} |

how about using a trace node for writing to a file instead of JCN

I need to change the file name dynamically ..there should be a new file as the date changes.
we cannot do that in trace node  |

But you can write a file from the Trace Node, and then use a utility, fired off each day, to "rotate and trim" the file.

Use v6.1 and the FileOutput node.
Otherwise, there may indeed be many different ways to write to a file in Java.
There is no way to write to a file from ESQL, without talking to Java.
The "best" way to do this may depend entirely on very specific things that are local to your situation.
