Incomplete HTML Returned by Servlet

I'm having a problem where incomplete HTML is being returned to the client (browser) by my servlet. This is (obviously) causing problems with the HTML page creation at the browser.
To create the HTML, I'm getting a handle to the output stream, creating the HTML code using a series of println commands, then closing the output stream:
PrintWriter out = response.getWriter();
out.println("<HTML><HEAD>");
out.close();
However, the web page is rarely completely sent (it's pretty big, but no bigger than some I've seen) before the browser (tries) to display it.
The servlet works perfectly when I'm running it locally. As soon as I try to run it off a shared server (or from an ISP), the problems arise.
I'm considering resetting the buffer size with a HttpServletResponse.setBufferSize(), but I'm not sure if that's the problem.
Any ideas?

I've also seen similar behavior when forwarding
requests between servers where one server supported
"chunked" transfer encoding, and the other one didn't.
The first server would sent the response stream to the
second server in pieces, but the second server would
just send along only the first chunk to the client.That sounds possible (certainly describes what I'm seeing), except that I'm getting/putting and responding to/from the same (single) servlet.
I'm not familiar with "chunked" transfer encoding...is that some sort of HTML header setting?

Font error in html produced by servlet

I am writing a servlet that reads data from html form and displays the
input data in html form for confirmation.
The program uses japanese characters but when servlet shows the output
it doesnt show the japanese characters..instead ??? are displayed.
How can i solve this problem. Here's my code
public class MosiKomi extends HttpServlet {
       protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        // declaring the variables to assign the input from the form
        String firstName;
        String lastName;
        String furiganaF;
        String furiganaL;
        //Reading the input parameters from the form
        try {
            firstName = request.getParameter("firstname");
            lastName = request.getParameter("lastname");
            furiganaF = request.getParameter("furiganafirst");
            furiganaL = request.getParameter("furiganalast");
        }catch(){
            // exception error code
       return;
        //Printing the above information for confirmation
        // TODO output your page here
        out.println("<html>");
        out.println("<head>");
        out.println("<title>japanese characters</title>"); // japanese character is where i have the japanese characters written
        out.println("</head>");
        out.println("<body>");
        out.println("<h1>Jchar " + firstName + "Jchar"+ lastName +"</h1>" +"<br>"); // Jchar are the japanese characters
        out.println("<h1>Jchar" + furiganaF + furiganaL +"</h1>");
        out.println("</body>");
        out.println("</html>");
        //out.close();
    }Any comment on the codes will be highly appreciated too.(like..bad designing...or it would be better this way etc.)
Thanx in advance

However I am stuck with this part.
The user inputs the japanese characters in the form and submits it.

How to send HTML DOM to Servlet?

How to send HTML DOM to Servlet?

What exactly you mean by sending DOM to servlet?? if you want to post the entire html to servlet use XMLHttp object and post the entire html to servlet. You can get more info on XMLHttp at microsoft's MSDN site.

How to call a html page from servlet

i want to link a servlet to a html page, if i use requestdispatcher, it says XXX.html is not available, can anybody help

Can you be more specific about what you're trying to do? Can't read your mind =). But if you mean you want to just have an static HTML page such as a header read by the servlet you can you the requestdispatcher include().
Create a servlet to generate a page, and then map it as /getPage in the web.xml file. Then you can use:
// header
RequestDispatcher rd = ...getRequestDispatcher("/getPage");
rs.include(req, res);
// the rest of the servlet output
// and you can do another one for the footer down here
rd = ...getRequestDispatcher("/getPageFooter");
rs.include(req, res);
and it'll output the HTML in the servlet.
Hope this helps

Get HTML source from servlet or strut action

Hi, need ur help
I would like to get the HTML source code after calling a URL, for example,
Suppose a servlet will return a page hello.html, i would like to grap this HTML page source code in my servlet or strut action.
How can i achieve this?
Thanks

This question does not make sense, because the Servlet is the thing that generates the HTML in the first place.
If you want to view the HTML source of a given web page. Go to 'View'->'Source' in Internet Explorer.

PeopleSoft Invoking BPEL process gets HTML returned and not XML

I am executing a SyncRequestXmlDoc in PeopleCode to call a BPEL process.
In an earlier demo environment this works fine and when I interrogate the log I get a correct Request and Response message :
I have now installed SOA Suite and I am deploying to that and I now have a problem with the Call.
It works.... but does not execute the BPEL Process.
Investigation has found that the PeopleTools Synchronous Message log shows the failing call as returning the HTML form of the BPEL process instead of the XML.
Detailed below are the request and response logs for the working process and then the failing process.
The question is :
Is the BPEL process launched by SOA suite being returned in HTML form because of a setting or configuration issue or .... ?
I can run the failing process from the BPEL Console without any problems ?

Is this a setting or configuration problem in my SOA suite install ?
Needless to say the BPEL process does not execute.
Can anyone help ?

Hi Lonneke
Thanks for responding....
You are correct in seeing that the two services are different in name.
However they are identical in function.
I created the service POSyncComp in my earlier version of JDev and deployed it to my local OC4J.
Which is launched by a PeopleSoft call using PeopleCode.
I have now rewritten this service in my new JDev and called it POSyncCompInt and deployed to home in an SOA suite implementation.
So whilst I test and before I roll the original service call out, I have both.
I have duplicated the PeopleCode and tweaked the message call, so that for testing purposes, and before I drop the current working version I have both calls in my PeopleCode event.
The original POSyncComp call still works, but the call to the 'new replacement' does not.
Hence the log shows both calls.... with slightly different names.
The strange thing is that the PeopleSoft LOG shows very similar code in the Request Message, but the response from the new call shows the HTML Form that I get if I run the second BPEL process from the SOA BPEL console.
So it looks like it is addressing the URL correctly.... but it suggests that stand alone OC4J returns a different response to the SOA suite which I am using for the new version of the BPEL process.... Is this configuration ?
It hints at the xsd file and the complex message type at entry to the BPEL process.
I can run the new process from the SOA suite BPEL Console with no problems.
I hope that clarifies your question about two different service names

Inserting Image on a HTML page through servlet

Problem in(IE 6) Opening non-html files using Servlets (Urgent)

Hi,
My application developed using struts 1.3 have an option to upload and download any kind of files.
The uploaded files shall be displayed as hyperlinks in the HTML page. On click of a hyperlink, a servlet shall be called and the corresponding file shall be opened as an attachment. But i am facing problem in opening the files.
The problem is,
Whenever i try to open a file of type (.doc or .xls or .pdf) the browser(*IE 6*) does not identify the content type. So it opens the content in a browser as binary content. But it works perfectly in IE 7 and firefox. (I used mim.types file to fetch the content type dynamically based on the file chosen)
However, the code i used to open a .doc file is,
response.setContentType("application/msword");
response.setHeader("Content-Disposition", "attachment;filename="+content.getFileName());
response.setContentLength(content.getStream().size());
ServletOutputStream out;
out = response.getOutputStream();
content.getStream().writeTo(out);
out.flush();
content - is a TO which shall hold the fileName and ByteArrayOutputStream ,etc.
Please anyone can help me solving this issue.
Thanks,

thanks..
its working fine now. i just added response.reset() before setting the properties of HTTPResponse object.

Uploading File To MySQL from HTML form via Servlet

Hello all !

Here's what I'm trying to accomplish:
1) client submits a JPEG image via a simple html form on a webpage.
2) JPEG is put into a database table, column field of type BLOB.
3) Servlet processes the request, gets a connection to the db and inserts the image into the table.
4) after that user is able to retrieve an image from db and display it in JSP page.
This is pretty much the same task Angela was trying to do here:
http://forum.java.sun.com/thread.jspa?threadID=667597&messageID=3905449
I could use her snippets if i knew what is what and decided to figure out this myself. Aftet some investigation i found out that i need to import org.apache.commons.fileupload.*;which i found here: http://jakarta.apache.org/commons/fileupload/
what am i driving at ?
-----------------------1-----------------------
After first line of code
boolean isPart = FileUpload.isMultipartContent(request);netBeans 5.5 beta2 with bundled Tomcat 5.5.17 underlines this with warning saying that
org.apache.commons.fileupload.FileUploadBase
has been depreceted
is it a reason for concern ?
-----------------------2-----------------------
Is it actually good idea to store images in db as blob ?
what about large ammounts of text ?
thank you

is it a reason for concern ?Yes.
You should take a look at the method in the documentation and find out exact reason for depricating it.
If it is depricated becouse they going to remove it in the future you should use the new alternative method becouse if you use the old method your app will not work in the future releases of the API.
If it is depricated becouse it is not safe to use the method you should clearly understand the risks involved in using the method and see if that can give you any trouble in your project.

Is it actually good idea to store images in db as
blob ?I think that it is ths best option available when you want to store binary data
what about large ammounts of text ?You can use clob columns.
By the way when you store files in the database its better you put some extra columns to store the file name and file type(mime) becouse you cant directly detect those things later by just looking at the data of the file.

Setting fields on html page from servlet

I have a HTML Page1 on ServerA that calls a servlet on ServerB. I want the servlet to load Page2 on ServerA and set fields on Page2.
I know I can do so by using Redirect and passing parameters in the URL that can be loaded in the onLoad event of Page2 but I was wondering if there is some way I can cause the servlet to set the fields directly.
I have looked a getRequestDispatcher("url").forward but it seems to me that the page being called would have to be on ServerB (the servlet's server). Am I correct? If not how do I get this to work? I have tried getRequestDispatcher("Page2").forward() and getRequestDispatcher("/Page2").forward() but neither seem to work. I assume because the pages are expected to be found on the servlet's server?

thank you!
I do put a bounch of System.out.println statements in it. one is just before the out.println("<html>") statement. another is before response.sendRedirect(). My program can print out each of the System.out.println(). but stop after that.I really do not know why!

Accesing a html parameter from servlet is not producing in a new file

Hi,...
I have passed two values from html and accessed thru a servlet file.
In servlet, parameters are verified and result must passed to a new jsp file.
Wen i run the file i can view only a blank page.I think the problem will be in servlet mapping.
verify my coding and give me a result.
I wer using net bean 6 with glassfish v2 server.
public class Logverifier extends HttpServlet {
* Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
* @param request servlet request
* @param response servlet response
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
/* TODO output your page here
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet Logverifier</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet Logverifier at " + request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
ServletConfig config=getServletConfig();
String user=config.getInitParameter("user");
String pass=config.getInitParameter("pass");
ServletContext context=getServletContext();
RequestDispatcher reqdis=context.getRequestDispatcher("menu.jsp");
RequestDispatcher reqdis1=context.getRequestDispatcher("login.jsp");
if((user.equals(request.getParameter("user")))&&(pass.equals(request.getParameter("pass"))))
reqdis.forward(request, response);
else
reqdis1.forward(request, response);
} finally {
out.close();
<servlet>
<servlet-name>Logverifier</servlet-name>
<servlet-class>com.Logverifier</servlet-class>
