Problem with HttpServletResponse
I have a problem with HttpServletRensponse.
I implemented a short program that executes a download from a blob
field to a client browser with jsp, but after the commit of "response"
the client browser remains waiting. I close all streams and all
connections but the problem persists. Anybody has an answer for this
problem?
thanks Guys!!!!!
Look back through the JSP and Servlet newsgroups for "download" ... working
code has been posted before.
It is do-able. FileServlet is Weblogic is the thing that serves up all
images and static HTML, so it must be possible!

Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
Out.println() problems with large amount of data in jsp page
I have this kind of code in my jsp page:
out.clearBuffer();
out.println(myText); // size of myText is about 300 kbThe problem is that I manage to print the whole text only sometimes. Very often happens such that the receiving page gets only the first 40 kb and then the printing stops.
I have made such tests that I split the myText to smaller parts and out.print() them one by one:
Vector texts = splitTextToSmallerParts(myText);
for(int i = 0; i < texts.size(); i++) {
out.print(text.get(i));
out.flush();
}This produces the same kind of result. Sometimes all parts are printed but mostly only the first parts.
I have tried to increase the buffer size but neither that makes the printing reliable. Also I have tried with autoFlush="false" so that I flush before the buffer size gets overflowed; again same result, sometimes works sometimes don't.
Originally I use such a system where Visual Basic in Excel calls a jsp page. However, I don't think that this matters since the same problems occur if I use a browser.
If anyone knows something about problems with large jsp pages, I would appreciate that.Well, there are many ways you could do this, but it depends on what you are looking for.
For instance, generating an Excel Spreadsheet could be quite easy:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class TableTest extends HttpServlet{
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
response.setContentType("application/xls");
PrintWriter out = new PrintWriter(response.getOutputStream());
out.println("Col1\tCol2\tCol3\tCol4");
out.println("1\t2\t3\t4");
out.println("3\t1\t5\t7");
out.println("2\t9\t3\t3");
out.flush();
out.close();
}Just try this simple code, it works just fine... I used the same approach to generate a report of 30000 rows and 40 cols (more or less 5MB), so it should do the job for you.

Hello all,

I'll appreciate all help.
kari-mattiHello again.
I'm still having problems with this. I made
a simple servlet that reads from and writes
to text file. The reading part work fine on my
computer, but the writing doesn't, not even
an exception is thrown if the file exists that
I'm trying to write to. If I try to create a new
file I'll get an exception about file permissions.
I also asked a friend of mine to try this same
servlet on his windows computer and it works
as it should.
Here's the code
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class ReadServlet extends HttpServlet
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
String s = "";
PrintWriter out = response.getWriter();
String docroot = getServletContext().getRealPath( "/" );
out.println("docroot: "+docroot);
File file = new File(docroot+"test.txt");
if(file.exists())
s = readFile(file);
out.println(s);
else
out.println("file not found");
//file.createNewFile(); // causes exception
//out.println("new file created.");
writeFile(file, "written by servlet");
out.println("Now look in the file "+file.getPath());
out.println("and see if it contains text 'written by servlet'");
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
doPost(request, response);
private String readFile(File file)
FileInputStream fis = null;
BufferedInputStream bis = null;
DataInputStream dis = null;
String s = "";
try
fis = new FileInputStream(file);
bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
s = dis.readLine();
fis.close();
bis.close();
dis.close();
catch(Exception e)
e.printStackTrace();
return s;
private void writeFile(File file, String s)
FileOutputStream fos = null;
BufferedOutputStream bos = null;
DataOutputStream dos = null;
try
fos = new FileOutputStream(file);
bos = new BufferedOutputStream(fos);
dos = new DataOutputStream(bos);
dos.writeChars(s);
fos.flush();
bos.flush();
dos.flush();
fos.close();
bos.close();
dos.close();
catch(Exception e)
e.printStackTrace();
}And if someone wants to test this servlet I can
give a war package.
Any advices?

Problem with non-ASCII file name in content disposition header
Hi All,
I am facing some problems with the non-ASCII file name incase of content-disposition header. I read from the RFC 2183 that if the file name contains non-ASCII characters then the same should be encoded before sending to browser. I did the same but realized 2 problems:
1. The name of the file is truncated in case the file name is slightly long for e.g. �����������j�b�g��������������������������.txt
2. Also when the same file is opened in notepad, the title is showing encoded name %E6%9C%80%E4%B8%8A%E4%BD%8D.....
Overall, I feel that the browser is not understanding or responding to the encoded header values.
Is there any solution to this problem? I am using Microsoft IE 6.0.
The code snippet is given below:
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String fileName = "�����������j�b�g��������������������������.txt";
fileName = URLEncoder.encode(fileName, "UTF-8");
resp.setCharacterEncoding("UTF-8");
resp.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
resp.setContentType("application/download-binary");
String s = "This is inside txt file";
resp.getOutputStream().write(s.getBytes("UTF-8"));
return;
}Any help or pointer would be highly appreciated.
Thanks and Regards,
AshishThe MIME standards for non-ASCII filenames are not widely implemented.
Many mailers use an ad hoc method for encoding filenames. JavaMail
supports both methods, but you need to set properties, such as the
mail.mime.encodefilename property. See the JavaMail javadocs for
the javax.mail.internet package. -
Problem with running multiple servlet in same webapplication with tomcat 3
Hi all,
I am using Tomcat 3.0 as webserver with jdk1.3, Servlet 2.0,
Templates for html file and oracle 8i on UNIX platform.
I have problem with multiple servlet running same webapplication.
There are two servlet used in my application. 1) GenServlet.class
and 2) ServletForPrinting.class
All of my pages go through GenServlet.class which reads some property files
and add header and footer in all pages.
I want reports without header & footer that is not possible through GenServlet in my application.
So I have used another servlet called ServletForPrinting --- just for reading html file.
It is as follow:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletForPrinting extends HttpServlet {
public void service (HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
// set content-type header before accessing the Writer
response.setContentType("text/html");
PrintWriter out = response.getWriter();
File f1 = null;
String report = null;
String path = request.getPathInfo();
try{
String p = "/var/home/latif/proj/webapps/WEB-INF/classes" + path;
System.out.println(p);
f1 = new File(p);
p = null;
if (f1.exists()) {
FileReader fr = new FileReader(f1);
BufferedReader br = new BufferedReader(fr);
report = new String();
while ((report = br.readLine()) != null) {
out.println(report);
}catch(Exception e) {
out.close();
report = null;
path = null;
f1 = null;
} // end class
It works fine and display report properly.
But now Problem is that if report is refreshed many times subsequently,
WebServer will not take any new change in any of java file used in web-application.
It works with the previous class only and not with updated one.
Then I need to touch it. As soon as I touch it, webserver will take updated class file.
Anybody has any idea regarding these situation?
Is there any bug in my ServletForPrinting.java ?
Any solution ????? Please suggest me.
Suggestion from all are invited. That will help me a lot.
Thanks in advance

I would strongly suggest at least reading this tutorial to give you an idea of why your fix worked (or maybe only appeared to work). Myself, I never just throw up my hands and say, "Whatever," and wash my hands of the situation without trying my best to understand just what fixed it. Guranteed you'll run into the same/similar problem and this time your fix won't work.
Please do yourself a favor and try to understand why it is working now, and save yourself (or more likely, the next poor dev to work on this project) some heartache.

A simple problem with sateful Session beans
Hi,
I have a really novice problem with stateful session bean in Java EE 5.
I have written a simple session bean which has a counter inside it and every time a client call this bean it must increment the count value and return it back.
I have also created a simple servlet to call this session bean.
Everything seemed fine I opened a firefox window and tried to load the page, the counter incremented from 1 to 3 for the 3 times that I reloaded the page then I opened an IE window (which I think is actually a new client) but the page counter started from 4 not 1 for the new client and it means that the new client has access to the old client session bean.
Am I missing anything here???
Isn�t it the way that a stateful session bean must react?
This is my stateful session bean source.

}You are injecting a reference to a stateful session bean to an instance variable in the servlet. This bean instance is shared by all servlet request, and that's why you are seeing this odd behavior.
You can use type-leve injection for the stateful bean, and then lookup the bean inside your request-processing method. You may also save this bean ref in HttpSession.

Hi Everyone
I have made the login() method but i am facing the problem while making the resource context...Because in Resource Context it takes IUser of package
com.sapportals.portal.security.usermanagement.IUser but I have got IUser of package com.sap.security.api.IUser ...while type Casting it with below code it is giving ClassCAstException.......
public class NewSimpleServlet extends HttpServlet {
protected void doGet(
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
StringBuffer s = new StringBuffer();
try {String j_user="epuser";
String j_password="Abcd1234";
request.setAttribute("j_user", j_user);
request.setAttribute("j_password", j_password);
javax.security.auth.Subject subject;
Set principals = UMFactory.getLogonAuthenticator().logon(request, response, "uidpwdlogon").getPrincipals();
i have problem with getting IUser object from set of principals. In javadoc is written: "In order to get an IUser object from this subject, call Subject.getPrincipals() and iterate through the returned Set of principals." so i tried to iterate but i was not able to get that IUser with any casting. Do u know how it should be?
IUser serviceUser = (IUser)subject.getPrincipals().iterator().next();
Now in resource Context
ResourceContext c = new ResourceContext(User);
Here resource context need IUser type object as parameter...
I also tried st like this
loggedUser = UMFactory.getAuthenticator().getLoggedInUser(request, response);
but loggedUser is not authenticated.
Can Anyone Help me Out...
Thanks

Problem with Non JSF Request to JSF Page
Hi All,
I am working on dynamic controls generation based on the request come from non jsf page
For the first request, pageworks perfectly. but when we go for second request, it is not rendering and I am getting same old page.
What I have identified is if I have 2 pages as JSF, application is not giving any problem.
For this I have written small test application contains both JSF pages only.
page1 contains 3 submit buttons.
When submit buttons are clicked based on the request, I get, am able to see the dynamic controls.
SO there is no problem with JSF PAGE to JSF Page Communication
Now I have done some changes in First JSF page. Instead of submitting directly I am submitting the page through JavaScript which is nonb JSF request. There I am facing the problem and based on requested qaction I am not able to see correct rendered page based on the requested action.
Any Idea why it is giving problem for non JSF requests??
Thanks
SudhakarFor Your Convenience in understanding the problem
I am pasting entire test code
Page 1 -- (here page2 is Page1 and Page1 is page2 - some naming convention errors :) )

Problem with HttpSessionBindingListener
Hi
I have a problem with HttpSessionBindingListener.
The sesion timeout in web.xml is 10 min.
I open sesion 1 at 10:00 am
I open sesion 2 at 10:05 am
The valueUnbound method is called twice at 10:15 am
The problem is that the valueUnbound is fired only when the last sesion on the site gets timeout. If the example worked well:
The valueUnbound would called would be fired at 10:10 am (sesion 1)
The valueUnbound would called would be fired at 10:15 am (sesion 2)
The example code is very easy:
public class ususs extends java.lang.Object implements HttpSessionBindingListener
private String userName;
public ususs(String userName) {
this.userName=userName;
public void valueBound(HttpSessionBindingEvent event)
userName="kk";
public void valueUnbound(HttpSessionBindingEvent event)
userName="";
... And request.getSession().setAttribute("oUsuss", new ususs("myuser")); when the user logins
ThanksThe ConnectionCloser code:
public void valueBound( HttpSessionBindingEvent event )
System.out.println( "[ConnectionCloser::valueBound]" );
public void valueUnbound( HttpSessionBindingEvent event )
System.out.println( "[ConnectionCloser::valueUnbound]" );
}The login method, session.setAttribute should invoke valueBound in ConnectionCloser
private void login( HttpServletRequest, HttpServletResponse)
throws ServletException, IOException
HttpSession session = request.getSession( true );
Integer oTilr = (Integer)session.getAttribute("tilr");
if( oTilr!=null && oTilr.intValue()>MAX_TILRAUNIR )
villubodTilNotanda( "Of margar ....
else
try
Connection cTengingNotanda = Vinnsla.login(...
session.setAttribute( "tn", cTengingNotanda );
sendaSvar( "Innskr?ning t?kst" );
catch( Exception e )
Integer oT2 = null;
if( oTilr!=null )
oT2 = new Integer(oTilr.intValue()+1 );
else
oT2 = new Integer( 1 );
session.setAttribute( "tilr", oT2 );
villubodTilNotanda( "Sennilega ...", response );
}The logout method: session.invalidate() should invoke valueUnbound in ConnectionCloser
private void logout( HttpServletReq. request, HttpServletResp. r )
throws ServletException, IOException
HttpSession session = request.getSession();
if( session == null )
villubodTilNotanda( "?? ert ekki innskr??(ur)...
else
session.invalidate();
skilabodTilNotanda( "?tskr?ning t?kst", response );

WLS 7.0 sp2 - Servlet Problems with SOAP messages
I'm using Weblogic 7.0 SP2 and trying to create a Servlet to receive SOAP wrapped
XML messages. I'm getting the following error. Is this a problem with WLS7.0sp2's
support of JAXM? The System.out.println's indicate I have successfully received
the incoming SOAP request and then successfully formatted the SOAP response, but
upon returning saving the response it appears to blow up. Does anyone have any
suggestions?
I need to do the following in a servlet:
- receive an incoming SOAP request with an embedded XML message
- perform some processing
- return a SOAP response with an embedded XML message
Should I be using JAXM? Or can I do this same task easily with JAX-RPC?

Michael,
I got the same error on WLS8.1/Win2K professional and apache FOP (old version).
After digging into the WLS code and FOP(old version). i found the conflict happens
on
the "org.xml.sax.parser" system property. In WLS code, they hard coded like the
following when startup weblogic server:
System.setProperty("org.xml.sax.parser", "weblogic.xml.jaxp.RegistryParser");
But the FOP code try to use the "org.xml.sax.parser" system property to find the
sax parser then conlict happens.
Here is the response from BEA support :
"I consulted with our developers regarding the question of whether we can change
the hard-coded value for the java system property: org.xml.sax.parser by using
a configuration parameter and I found that unfortunately there is no specific
setting to change the value. As you had mentioned in your note the org.xml.sax.parser
system property can be changed programmatically in your application code."
I solve my problem by using newer apache FOP (it never use the system property:org.xml.sax.parser
any more) and XML Registy for WLS8.1.
Good luck.

Help.
When we migrated from WLS 6.1 to WLS 7.0 SP2 when encountered a problem
with XML
parsing that did not previously exist.
We get the error "weblogic.xml.jaxp.RegistryParser is not a SAX driver".
What does this mean? And, what should we do about it.

Problem with Enterprise Portal
Hi SAP gurus,
I am having a peculiar problem with my E-portal.
The system is up and running and when i check through jcmon, all my processes are running OK.
When i go the portal link, the login page also opens(sometimes immediately/sometimes takes a bit of time).
However, when i try to login with any user ID or j2ee_admin/admininstrator,it takes ages.
I have found some errors in /usr/sap/DP1/JC06/j2ee/cluster/server0/log/system/.

If anybody has faced this issue, kindly help.
Regards,
Santosh BhatI did a research of this issue, and I found a know issue on portal 7.0 SP16 that this message throws. The solution on this case is upgrade your system to sp17.
Your exception also say that your string "String processName = request.getParameter("processName");" Already exist before. so maybe this can be caused also for some custom code, this is a pssibility?
jsp_CrashesList1279627480225.java:253: processName is already defined in _jspService(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse).
Just to let you know the error of the know issue I referred is exacly:
The error is:
com.sap.engine.services.servlets_jsp.server.jsp.exceptions.CompilingExce
ption: Error while executing the compilation process:
[D:/usr/sap/HGE/JC04/j2ee/cluster/server0/apps/sap.com/tcmonitoringsys
teminfo/servlet_jsp/sap/monitoring/work/jsp_CrashesList1222431016884.jav
a:253: processName is already defined in _jspService
(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletRes
ponse)
#String processName = request.getParameter
("processName");
What I can recomend you is:
1) If you are on SP16, please evaluate upgrade your system to sp17.
2) Make suren this issue are not caused for any custom code.
3) try to go to last path level for the componente that are available on Market Place:
Obs: Just remember that Paths is not a a SP level, so has just corrections.
