In Servlet, response.sendredirect using iPlanet

I'm from INIDIA. I have some problem in using response.sendRedirect. I'm using iPlanet application server. I tested on Java Web Server and it's working fine there but please advice me, how it'll work on iPlanet.
Thanks

Should work the same way. If you have an actual problem when you try it, let us know.

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

What referer we get if we use response.sendredirect

I have Message.jsp page .This has one form This form on submitting calls servelt.After completing processing Servelt redirect to Message.jsp .The code is
response.sendRedirect("Message.jsp");
When i get referer in Message.jsp using request.getHeader("Referer");
i get Message.jsp(not showing full path).
I want to know is it normal behavior bcoz what i expect referer should be servelt
Thanks Vijay

Actually standard solution for this is confirming the TO with difference.
In this case the missing 2 PCS would go to storage type 999 and dynamic storage bin
address as your picking TO number.
When you finish the process you will have this situation:
- 3 PCS confirmed for your reservation
- 2 PCS sent to 999 storage type - "TO number" storage bin
- Then do a reversal of your material document for 2 PCS and close the reservation for the missing 2 PCS
- Close open transfer requirements, LL01 or LB11, or any LBxx that suits you
- Then you can clear the positive quantity from 999 by LI21 during Phys.Inv.
This should be clean and leaves no problems behind.

Using iPlanet with XSQL Servlet

Anyone have any information on how to configure the XSQL Servlet to work with iPlanet?
TIA

It won't work because iPlanet 4.1 has a broken implementation of the Servlet API's getRealPath() method, the method that XSQL Servlet uses to resolve virtual paths into absolute paths.
I just debugged a complaint that it didn't work with iPlanet this week and this was the result I found.
Their path resolution works for their own JSP implementation, but not for any other servlet.

Calling a bean in weblogic 4.5 from a servlet which is in Iplanet webserver4.1

while Calling a bean in weblogic 4.5 from a servlet which is in Iplanet webserver4.1 sometimes the servlet is not able to call the bean. There is no error logged in webserver. This is happening very rarely and when it happens I have to shut and restart IplanetWS.
Can anyone tell me some solution or reason

We did receive a 4.5.1 / 5.1 interoperability patch - but it wasn't quite 'seamless'.
We never tried to use it.
SOAP? Isn't that around 50 times slower than RMI?

of people using WL ejbs from Tomcat. This issue has caused us to avoidusing
WL ejbs in any future development which has any chance of ever beingused
by any
app server (WL included) that is not under the direct control of thedata

I've been trying to convince the Architecture team here that we canuse WL
EJBs
and we can call them from other app servers - but can't seem to getany
supporting

Anyway, a response from BEA would be appreciated.

IOException - WEB8001 - when writing to servlet response outputstream

I am attempting to port a Java servlet application from iws 6.0 to 6.1, sp2, but am encountering IOExceptions during load testing.
The servlet composes its response in a character array, and then calls the following method to write the characters to the servlet response object:
static void writeResponse( HttpServletResponse response, char[] chars, String charset ) throws IOException {
    OutputStreamWriter writer =
        new OutputStreamWriter( response.getOutputStream(), charset );
    char[] buffer = new char[8192];
    CharArrayReader reader = new CharArrayReader( chars );
    int read = 0;
    while(( read = reader.read( buffer, 0, 8192 )) > -1 )
       writer.write( buffer, 0, read );
    writer.close();
}Under moderate load (2-4 simultaneous connections), an IOException will sometimes be thrown. The stack dump is:
java.io.IOException: WEB8001: Write failed
     at com.iplanet.ias.web.connector.nsapi.NSAPIConnector.write(NSAPIConnector.java:750)

of data when the exception is thrown.
Any clues about how I might debug this?

What are you using as your test client?The test client is WebStone 1.0. WebStone always downloads the whole response, and reports the size of the response in bytes. From this I can see that when the IO exception occurs, webstone is unable to read the whole response, as it reports a smaller size.
So, I do not think the problem is that the client has prematurely aborted its download. WebStone doesn't work that way. I think something has gone awry on the server side, and this worries me.

Response.sendRedirect() from doEndTag() method

Hi there,
I am trying to call response.sendRedirect("url") in a custom tag doEndTag() method but for or some reason I cannot get access to the javax.servlet.http.HttpServletResponse object where this method lives. Does anyone know how I can do a response.redirect from a doEndTag() method? I've searched the forum and it appears other people can do it but I'm not sure how?
I can get access to javax.servlet.ServletResponse object by using pageContext.getResponse() but that doesn't give me the response.sendRedirect method. Can anyone help? What am I doing wrong?
Thanks for your help.
Cheers,
Brent.

you can pass the response object as argument to your
method..Thanks for your response!
Unfortunately I can't change the doEndTag() method parameters as doEndTag() is defined in the Tag interface. But if you mean pass the response object as an attribute of the tag i suppse that is possible.
However, that's pretty close to the hack I currently have to work around this problem except I'm putting the response object in a request attribute in the page and then retrieving it in the doEndTag() method.
But I am after something a little cleaner than either of these options..... I'm hoping I can just get the response object from another object I have access to. Any more thoughts?

Weblogic 6.0 (SP2) generates incorrect java code for JSP with response.sendRedirect()

 Hi,
 Here are the steps to reproduce the problem with the examplesWebApp application
 bundled with wlserver6.0(sp2):
 Product: Weblogic server 6.0 (sp2)
 Browser: IE 5.0
 1. Add index.jsp as the welcome file in WEB-INF/web.xml
 2. Create index.jsp as below:
 <%
 response.sendRedirect("index.html");
 return;
 %>
 <html>
 <head>
 <title>Index JSP file</title>
 </head>
 <body>
 This is index.jsp file 
 </body>
 </html>
 3. Create index.html as below:
 <html>
 <head>
 <title>Index HTML file</title>
 </head>
 <body>
 This is index.html file 
 </body>
 </html>
 4. Run the examples server and make sure examplesWebApp is deployed on the examples
 server using the console
 5. Access the URL http://localhost:7001/examplesWebApp
 The page will display a compilation error as below:
 C:\bea\wlserver6.0\config\examples\applications\examplesWebApp\WEB-INF\_tmp_war_examplesServer_examplesServer_examplesWebApp\jsp_servlet\_index.java:89:
 unreachable statement
 out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\nThis is index.jsp page\r\n</body>\r\n</html>\r\n");
 ^
 and a look at the generated java code for index.jsp (_index.java) will reveal
 the erroneous code snippet below in the jsp service method:
 try { // error page try block
 //[ /index.jsp; Line: 1]
 response.sendRedirect("index.html"); //[ /index.jsp; Line: 2]
 return; //[ /index.jsp; Line: 3]
 out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\nThis is index.jsp page\r\n</body>\r\n</html>\r\n");
 } catch (Exception __ee) {
 while (out != null && out != _originalOut) out = pageContext.popBody();
 pageContext.handlePageException(__ee);
 The above web application works fine in Tomcat 3.2.X environment. The Weblogic
 server 6.0 servlet engine should not generate the "out.println()" corresponding
 to the html section of index.jsp. The moment it sees the "return", it should stop
 processing further.
 Can someone from Weblogic support team please verify this and let me know when
 this bug will be fixed?
 One interesting thing I noticed was when we last tried weblogic 6.0 at its beta
 stage, it worked fine after we put in a special patch jar file called "redirectfix.jar"
 we received from weblogic team but somehow it got re-introduced by the time it
 was released!!
 We are planning to migrate our product from tomcat 3.2.x to weblogic 6.0. Our
 product has a lot of pages with such conditional {response.sendRdirect("page.jsp");return;}
 blocks. We would really appreciate a faster response form weblogic team.
 Thanks in advance.

Why should it stop when it sees a return? Is that in the spec?

HTTP error 302: response.sendRedirect()

Hi everybody,
I have a first servlet (AGSenderServlet) sending a file to a second one (AGReceiverServlet). This second servlet I'm receiving a file and then redirect to a JSP page. But I'm getting the following exception:
13-Sep-2010 13:20:42 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet AGSenderServlet threw exception
java.io.IOException: Received HTTP status code 302
        at AGSenderServlet.doGet(AGSenderServlet.java:43)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)
        at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)
....I've looked on internet and apparently the error 302 is linked to response.sendRedirect().
Here is my code:
public class AGReceiverServlet extends HttpServlet {
     public void doGet(HttpServletRequest request,
            HttpServletResponse response)
     throws ServletException, IOException {
         // Create a factory for disk-based file items
          DiskFileItemFactory factory = new DiskFileItemFactory();
         // Create a new file upload handler
          ServletFileUpload upload = new ServletFileUpload(factory);
          String realPath = this.getServletContext().getRealPath("sync/in");
          List items = null;
                    try {
                         items = upload.parseRequest(request);
                    } catch (FileUploadException e) {
                         e.printStackTrace();
                    // Process the uploaded items
                    Iterator iter = items.iterator();
                    try {
                         String fileName = "blabla";
                         while (iter.hasNext()) {
                              FileItem item = (FileItem) iter.next();
                              // Process a file upload
                              if (!item.isFormField()) {
                                   fileName = item.getName();
                                   long sizeInBytes = item.getSize();
                                   //Write to File
                                   if (fileName != null) {
                                      fileName = FilenameUtils.getName(fileName);
                                   File uploadedFile = new File(realPath);
                                   if (!uploadedFile.exists())
                                        uploadedFile.mkdirs();
                                   uploadedFile = new File(realPath+"/"+fileName);
                                   item.write(uploadedFile);
                         System.out.println("http://"+request.getServerName()+':'+request.getServerPort()+"/upTool/filereceived.jsp?filename="+fileName);
                         String redirectURL = "http://"+request.getServerName()+':'+request.getServerPort()+"/upTool/filereceived.jsp?filename="+fileName;
                         response.sendRedirect(redirectURL);
                    } catch (Exception e) {
                         e.printStackTrace();
     public void doPost(HttpServletRequest request,
            HttpServletResponse response)
     throws ServletException, IOException {
               doGet(request, response);
}The file received is saved properly and is ok.
Using print out I have discovered that it was the running the whole code but not the code in filereceived.jsp (the JSP of the sendRedirect() ).
I have tried the url used in the sendRedirect() and it works ok.
Any idea?
Cheers.

The AGSenderServlet is sending a file to the AGReceiverServlet using multipart and Postmethod object. Here is the code.
public class AGSenderServlet extends HttpServlet {
     public void doGet(HttpServletRequest request,
            HttpServletResponse response)
     throws ServletException, IOException {
          String filename = request.getParameter("filename");
          String ext = request.getParameter("ext");
          String serverName = request.getParameter("serverName");
          String port = request.getParameter("port");
          String path = null;
          String uri = "http://"+serverName+":"+port+"/AGReceiverServlet";
          File file = new File((this.getServletContext().getRealPath("/sync/out"))+"\\"+filename+'.'+ext);
          System.out.println("Test = "+file.getAbsolutePath());
          PostMethod post = new PostMethod(uri);
        Part[] parts = new Part[] {
            new FilePart(file.getName(), file) // File you want to upload
        post.setRequestEntity(new MultipartRequestEntity(parts, post.getParams()));
        // Now perform the POST and check for errors
        HttpClient http = new HttpClient();
        int status = http.executeMethod(post);
        if (status != HttpStatus.SC_OK) {
            throw new IOException("Received HTTP status code " + status);
     public void doPost(HttpServletRequest request,
            HttpServletResponse response)
     throws ServletException, IOException {
               doGet(request, response);
}Line 43 is just throw new IOException("Received HTTP status code " + status);What do you mean by " then you should handle it." ? I think I handle it. It redirects to the JSP filereceived.jsp which is hosted and available on the server (tried to access it directly by entering the url and it works).

6.1 SP5: response.sendRedirect crashes

Hi all,
I am porting a JSP app from Iplanet 4.1 to SunONE 6.1 SP5 (Solaris 5.9).
When I try to do the above statement in a JSP, I get the following in the error log:

I am not sure what I need to declare differently in 6.1. The web app jars are in WEB-INF/lib under the docroot.
The code in the JSP is pretty standard, but ran under Iplanet 4.1.
try {
String URL = "https://www.ozbet.com.au/tab/ozbet.htm?p_date=" //has parameters;
response.sendRedirect(URL);
catch (ApplicationException e) {
//do some stuff here
%>
ERROR: <%= msg %>"
<%
FYI the webapp is working fine wrt to jdbc, jsp etc. It is just the sendRedirect() that is crashing.
Do I need to declare anything related to NSAPI in obj.conf ?
Please help and thanks in advance.

That's not a crash. HttpServletResponse.sendRedirect is throwing an IllegalStateException because you called it after the response had been committed. This is a documented part of the Servlet spec. (See, for example, http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/http/HttpServletResponse.html#sendRedirect(java.lang.String) for the the J2EE 1.3 docs.)
The most likely problem is that you're calling sendRedirect after an include or after outputting too much data. If you're going to call sendRedirect, you need to do so near the top of your JSP file, before you output a lot of data. Once data has been sent to the client, there's no way for the server to say "oops, never mind, ignore that data and redirect over here instead".

Sending Javascript call in servlet response.

I am calling a servlet from a javascript ( .js) file. Based on the status of the server I want send javascript function call to the client browser.
Is it possible?
Here is what I am trying to do :
response.sendRedirect("javascript:myfinction()");
myfunction() is defined in the source .js file from where I am calling the servlet.
Hope you understand what I am trying to do. Please help.
Thanks
Pradip

That won't be possible as the servlet executes first on the server, then javascript executes on the client.
Remember that Javascript requires the browser to do anything, it's the browser functionality that it runs in. The servlet executes on the server, then forwards to the client, and therefore has no access to javascript whatsoever, at least not in the context that you're speaking of. By the time javascript is ready to start, the servlet has already completed.
If it was the other way around, that would be possible (i.e. use JSP/Servlet to set javascript variable value).
Sorry.

Response.sendRedirect throws IOException

I am using jsdk2.0 and I am using servlet runner to test this servlet.
In my servlet if a person is authorized I am sending the person to a particular URL.
if(rs.next())
response.sendRedirect(response.encodeRedirectUrl("https://xyz.com"));
It does go to the URL but It throws a exception which I can see in the servlet runner... IT Says java.io.IOException: Tried to write more than the content length..
sun.servlet.HttpOutputStream.check(HttpOutputStream:java:282)..Dont have a 282 line...
Can someone tell me...I know I am using deprecated method but why is it giving an exception?

your using https which is not supported by sendRedirect as far a i know. There is a special package for ssl afaik.

Should I return after a response.sendRedirect?

I have this code in the beggining of my JSP page and it seems to work okay. My question is: is it okay to use the return keyword in a JSP page or does it cause problems. Would this practice be considered safe?
<%@page import="javax.sql.*,javax.naming.*" %>
<%
 // Don't let the browser cache this
 response.setHeader("cache-control", "no-cache");
 response.setHeader("pragma","no-cache");
 response.setIntHeader("expires", -1);
%>
<%
 // Determine if this web application is properly configured
 boolean notConfigured = false;
 Context i = new InitialContext();
 DataSource ds = (DataSource) i.lookup("java:comp/env/sqlServer");
 if (ds==null) notConfigured = true;
 i.close();
 String dataBase = application.getInitParameter("database");
 if (dataBase == null) notConfigured = true;
 if (notConfigured)
 response.sendRedirect("notConfigured.jsp");
 return;
%>

Since the JSP gets converted into a Servlet and whatever code that you write in your JSP effectively goes into the service() method of the generated servlet, it may not be appropriate to call return. This will not give any chance for the rest of the code (may be for cleanup) that may have been inserted by the JSP -> Servlet converter (or whatever it is called) to be executed.
However, I am not 100% sure on this. Very much interested to know more about this from somebody more knowledgeable on this.

Response sendRedirect is not working in JSF

Hi,
I am getting an error on calling response.sendRedirect() method in my backing bean. This piece of code is for redirecting:
            if (userCredentials.isExpired() || userCredentials.isInThreshold() ) { // Just checking for some boundary conditions
                ViewHandler vh = ctx.getApplication().getViewHandler();
                String viewUrl = vh.getActionURL(ctx, PATH_FOR_CHANGE_USER_PAGE);
                ExternalContext ectx = ctx.getExternalContext();
                HttpServletResponse response =
                    (HttpServletResponse)ectx.getResponse();
                response.sendRedirect(viewUrl);   /// This is where the error is thrown.
            }Here is the stack trace:

Yep, content has already been flushed to the browser and then the redirect cannot work anymore. Move the redirect logic to a filter I'd say.

In Servlet, response.sendredirect using iPlanet
