If you want to use URLConnection then the data written to the URL will be
available in the URL inputstream... Try this...

String XXX_URL

="http://localhost:8080/PGAC/Jsps/JSP/PGACMultiItemCriteriaPage.jsp";

URL url = new URL(XXX_URL) ;

InputStream is = url.openConnection().getInputStream();

int c=0;

String strVal = new StringBuffer();

while ((c = is.read()) != -1)

{strVal.append((char) c);}

I have a requirment to read a csv file which is passed from a property

file , and pass the string to a JSP page.

I am stuck as to how to pass the string from to JSP page from a standalone

code.

The way I coded is here:

Standalone code:

public class URLConnectionReader {

public static void main(String[] args) throws Exception {

String inputfilename="";

String strLine="";

String strVar="";

int counter, numberOfTokens = 0;

inputfilename=args[0];

try

{

FileReader inputFileReaderdump = new

FileReader(inputfilename);

BufferedReader inputFile = new

BufferedReader(inputFileReaderdump);

while ((strLine =

inputFile.readLine()) != null)

{

StringTokenizer

strTokLine = new StringTokenizer(strLine, ",");

numberOfTokens =

strTokLine.countTokens();

for (counter = 0 ;counter < numberOfTokens ;counter++ )

{

strVar = new String(strTokLine.nextToken());

strVar=strVar.trim();

System.out.println("the values of each token is

\t"+strVar+"\n");

}

}

}

catch (Exception e)

{

e.printStackTrace();

}

String XXX_URL

="http://localhost:8080/PGAC/Jsps/JSP/PGACMultiItemCriteriaPage.jsp";

URL url = new URL(XXX_URL) ;

URLConnection urlc = url.openConnection() ;

urlc.setDoOutput(true);

urlc.setDoInput(true);

PrintWriter pw = new PrintWriter(new

OutputStreamWriter(urlc.getOutputStream()), true) ;

pw.println(strVar) ;

}

}

and in the jsp page I have added a code as below"

InputStream is = req.getInputStream();

int c=0;

String strVal = new StringBuffer();

while ((c = is.read()) != -1)

{strVal.append((char) c);}

But still it is not working, please help me out in this.
