Why don't you append directly as a query string to URL and do
request.getParameter() in JSP ?

Subject: Help Needed: Http Get in java
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.
