JSP Open File
JSP Open File is used to create a file and write a text into the file.
Understand with Example
The Tutorial illustrate an example from JSP Open File. To understand the example we create openFile.jsp that include a page import directive "java.io" package. The java.io package provides for system input and output through data streams, serialization and the file system. For this, we have create a file 'Hello.txt' in the C:drive. The class FileOutputStream opens an output stream in order to write the specified text of line using the class PrintStream. In case the exception occurred , the catch block handle the exception and print the 'Unable to write to file'.
Here is the code of openFile.jsp
| <%@ page import="java.io.*"%> <% FileOutputStream out; try{ out = new FileOutputStream("C://Hello.txt"); new PrintStream(out).println ("All glitters are not gold"); out.close(); } catch (IOException e){ out.println ("Unable to write to file"); } %> |
When you run the above jsp code, the line of text, you have specified, will be written into the file Hello.txt.
