[iText-questions] method="post" instead of get to a servlet

Happynation Mon, 17 Jan 2005 14:41:35 -0800

Hello

I tryed do give a parameter with the methode post instead of get to a servlet. For trying i used the Example from your Website:

http://itext.sourceforge.net/examples/com/lowagie/examples/general/webapp/HelloWorldServlet.java

I changede the doGet into doPost and as well in the Formular method=“post“.

Now it works well from localhost. But if i try to call it from an other PC in the network it does not work.

If i Use get, it works well from localhost and from external PC.

If i use the post methode without iText (only generate HTML) it works too.

I running a Tomcat Webserver.

Thank’s for your help

import java.io.IOException;

import java.util.Date;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

public void doPost (HttpServletRequest request, HttpServletResponse response)

throws IOException, ServletException {

// we retrieve the presentationtype

String presentationtype = request.getParameter("presentationtype");

// step 1

Document document = new Document();

try {

// step 2: we set the ContentType and create an instance of the corresponding Writer

if ("pdf".equals(presentationtype)) {

response.setContentType("application/pdf");

PdfWriter.getInstance(document, response.getOutputStream());

}

else if ("html".equals(presentationtype)) {

response.setContentType("text/html");

HtmlWriter.getInstance(document, response.getOutputStream());

}

else if ("rtf".equals(presentationtype)) {

response.setContentType("text/rtf");

RtfWriter.getInstance(document, response.getOutputStream());

}

else {

response.sendRedirect("http://itext.sourceforge.net/tutorial/general/webapp/index.html#HelloWorld");

}

// step 3

document.open();

// step 4

document.add(new Paragraph("Hello World"));

document.add(new Paragraph(new Date().toString()));

}

catch(DocumentException de) {

de.printStackTrace();

System.err.println("document: " + de.getMessage());

}

// step 5: we close the document (the outputstream is also closed internally)

document.close();

}
