Outputting to .txt

[Yogendra Joshi]

Hello Ranchers ,

I have a page which has a Table which has details like name , password , address , telephone number etc...

Now this is displayed from the database nicely as i want to. Now i have a button saying EXPORT to .txt , Whatever data it shows on the Jsp i.e name,, password , address , telephone number etc on click of that button should popup an option to the user giving him / her an option to save the data as .txt file. I have tried response.setContentType(text/plain) and setting the header to .txt button , the file which is opening is outputting the source of the html page then the output which i am desiring i.e name , username etc.

Can someone please show me the light on how this can be achieved. Previously it was application/vnd.ms-excel and it used to save in excel , but now the users need it into a .txt rather then .xls.

Any help is much appreciated.

Thanks in advance.

In your action:

// Set response headers
response.setHeader("Cache-Control", ""); // no cache
response.setHeader("Pragma", ""); // no cache
response.setHeader("Content-Disposition","attachment; filename=My Filename"); // set filename
response.setContentType("text/plain"); // set contenttype
 
ServletOutputStream sos = response.getOutputStream(); // get response output stream
ByteArrayOutputStream bos = getFileByteArrayOutputStream(); // Get your txt file
response.setContentLength(bos.size());
bos.writeTo(sos);
sos.flush();
sos.close();
 
return null; // return no action forward

Hello thanks for the code, I have tried to put it.

It giving an exception saying method getFileByteArrayOutputStream(); cannot be resolved to a type. I have seen the API for ByteArrayOutputStream but didn't get any fruits out of it.

The Current code is :

  <html:form action="/callRegisterConsolidatedReportAction.do">
 
<%

  if((String) hs.getAttribute("CC")=="cc")
  {
        response.setContentType("application/vnd.txt");
        response.setHeader("Content-Disposition","attachment; filename=ConsolidatedReport.doc");
  }
  else response.setContentType("text"+"/html");%>
 
<table width="550" border="0" cellpadding="0" cellspacing="0"
align="CENTER">
<tr>
<td valign="top">
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>  

For the extension which we are using right now . i.e doc , its coming very perfectly. Also if the extension is .xls then its coming fine. Only for .txt it is giving problems. Can you please give us more idea on this ?

Thanks again.

getFileByteArrayOutputStream() is method I made up.

Replace it with a ByteArrayOutputStream of the txt file you want to display.

Hey Dom ,

Thanks for the immediate reply.

I think the getFileByteArrayOutputStream which you made up for you would work for me as well.. Can you post that too ?

Thanks

I just made up the method name.

If you tell me where you're getting the text file from (disk, string, etc..) I can help you convert it to an output stream.

[Dom Lassy]

If you have a String, here is how to get an output stream:

String theText = "Here is my text.";
byte[] byteArray = theText.getBytes();
ByteArrayOutputStream baos = new ByteArrayOutputStream(byteArray.length);
baos.write(byteArray);

I'm not sure if this will work because I haven't tested it or tried to complie it, but it shouldn't be too far off.
