Last servlet in request pipeline

Hi All ,
What is the last servlet in the request pipeline? Because I have a requirement to redirect to some other page based on our business logic.
Thanks in advance.

Last servlet pipeline: TailPipeline Servlet.
If u want to view servlet pipeline sequence, Browse to DynamoHandler(which is first servlet pipeline) in dyn/admin and go to nextServlet and so on.
From any servlet pipeline if u redirect to page. after processing ur page will get loaded.
No need to go to end and add ur servlet.
U can add it in middle also and use response.sendredirect.
Thanks,
Nitin..

Last active change request of a object which has been transported

Hi to all,
I need a method to obtain the last active change request of a object which has been transported to the corresponding target system. I know that the CR tables are E070 and E071, but how can I know the last active and transported CR of each object? Any suggestion?
Thank you very much,
Antonio

Hi Antonio, As u are aware that you can get TR information from E070 and E071 tables.From these two tables we can get the latest TR. In table E070 there are two fields with AS4DATE, AS4TIME.So, U can find the latest transported object on these two fileds.Also, u need to check the TRSTATUS field which specifies whether the object is transported ( R Released) or still Modifiable( Active as D).
However this table will also contains subtasks and main request. This can be diffrentiated with the help of STRKORR field of E070. If blank then its a main req else its a subtask where the field would contain the Main Request No.
Hope this would be of some help for u r development.
Regards,
Swaroop

Request Pipelining

Hi,
I am using iPlanet-WebServer-Enterprise/4.1SP3.
Does this support Request Pipelining or any other versions of
iPlanet-WebServer that supports it.
How to enable this feature.
Is there a way to test Request Pipelining. I am having IE5+, NN4.7, NN6,
NN6.1
Thanks in advance

There are many things wrong with your code. Learn the HTTP protocol and you'll know what I mean.
Here's a hint - you'r missing headers in your code.
Some servers do not support keep-alive connections, nor do you request a keep-alive connection.
Connection: keep-alive
Use that header field and see what happends. Also, in your while-loop, you actually close the output file and the socket. Don't you think it may be hard for the server to respond to a client that closed the connection on it?
1. You don't know HTTP
2. You don't seem to know Java
3. You don't seem to understand basic programming logic

Passing bean as attribute to servlet in request scope

Hello,
I want to pass a bean from a jsp to my controller servlet. As I understood, as long as I can give the bean 'request' scope, then I should be abble to access the bean, as an attribute in the doPost / doGet method of my servlet. However, when I try to get the bean in the servlet, its always null.
I am aware that request scope beans don't loose their values when passing to other JSP's , but what about passing to servlets?
I dont want to use a session scoped bean as I believe this should be possible with a request scoped variable.
<%-- vwLogon.jsp --%>
<jsp:useBean id="viewBean" class="com.alto.common.ViewBean" scope="request">
     <jsp:setProperty name="viewBean" property="viewName" value="/vwLogon"/>
</jsp:useBean>
<html>
<body>
<h2>Enter Name</h2>
<form method="GET" action="controller">
     Enter your name:<input type="text" name="vwLogon_User_txt" value=""/>
     Enter your password:<input type="secret" name="vwLogon_Password_txt" value=""/>
<input type="submit" name="vwLogon_Logon_Btn" value="Logon"/>
</form>
</body>
</html>
------------------------------- controller servlet
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
ViewBean viewBean = (ViewBean)req.getAttribute("viewBean");
String strURL = new String("");
if (!(viewBean==null)) {
strURL = viewBean.getViewName();

A request/response pair is one communication between the client browser and the web server. A submit form action generates a new request.
In this instance you have two requests:
1 - load login page
2 - submit login page
The point of being able to give a bean request scope, is so that you can use jsp:forward, or jsp:include to pass on the request, and the bean as well.
In your case, a session bean is probably called for, as you have 2 request/responses in your session.
Hope this clears things up a little.

[TOMCAT] [SERVLET] : The requested resource () is not available.

Hi!! I'm looking for an answer to my problem, and I'm going to explain what I mean.
I've created a .jar named yuhuuTunnel.jar that has the following structure:
yuhuuTunnel.jar:
--> web (contains the servlets)
      --> *.class
      --> HelloWorldServlet.class
--> META-INF
      --> MANIFEST.MF
--> SimpleClient.classThe code of HelloWorldServlet.java is this:
    package web;
    import java.io.IOException;
    import java.io.PrintWriter;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.ServletException;
    import javax.servlet.ServletConfig;
    public class HelloWorldServlet extends HttpServlet {
        public void init(ServletConfig config) throws ServletException {
            super.init(config);
        public void doGet( HttpServletRequest request, HttpServletResponse response )
                throws ServletException, IOException {
            doPost(request, response);
        public void doPost( HttpServletRequest request, HttpServletResponse response)
                throws ServletException, IOException {
            response.setContentType("text/html");
            PrintWriter out = response.getWriter();
            out.println("<html>");
            out.println("<body>");
            out.println("<body bgcolor=\"white\">");
            out.println("<h1>Yuhuu Servlet!</h1>");
            out.println("</body>");
            out.println("</html>");
    }then, using a .war file (created with ANT), I've created into /../tomcat/webapps/ a directory call yuhuuTunnel that has this structure:
    /webapps/
          --> yuhuuTunnel
                --> WEB-INF
                        --> web.xml
                        --> lib
                             --> yuhuuTunnel.jar
                --> META-INF
                        --> MANIFEST.MF
                             --> yuhuuTunnel.jar
                --> index.htmlThe content of web.xml is the following:

What is wrong? The address that I type into the browser or there's an error into web.xml?
Something interesting: If I type
http://localhost:8080/yuhuuTunnel/HelloWorld
the message given back is: "The requested resource () is not available."
but if I type

Servlet: "The requested resource is not available"

I'm trying to get my first servlet to run.
I've installed tomcat 4.1.18 and compiled a "HelloWorld" class into
"tomcat_dir"\webapps\root\web-inf\classes\.
when I start tomcat, then open my browser and key
"http://localhost:8080/servlet/HelloWorld"
I get a status 404
"The requested resource (/servlet/HelloWorld) is not available.
what am I doing wrong?
thanks
barry

Register the servlet in the web.xml file.
open ROOT/WEB-INF/web.xml and edit it like:
<web-app>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorld</servlet-class>
</servlet>
</web-app>
Stop and start tomcat and try again.

Windows 7 SP1 PRO SMB2 Client Behaviour Quirk - Last SMB2 Query_Info request in compounded requests, contains 1 extra byte in the end after file_id

Hi,
From the specification, SMB2 Query Info is defined as -Query_Info {
    uint16_t structure_size;
    uint8_t info_type;
    uint8_t file_info_class;
    uint32_t output_buf_len;
    uint16_t input_buffer_off;
    uint16_t res;
    uint32_t input_buf_len;
    uint32_t additional_information;
    uint32_t flags;
    uint8_t file_id[16];
I am looking at smb traffic between 2 Windows 7 Pro machines and I see that for SMB Query_Info Request records, for some compounded requests, the last Query_Info request has an extra byte after the 16 byte file_id. This is only for SMB2 Query_Info
requests.
On checking Query_Info requests that are single(not compounded), I don't see this extra byte.
I have attached images below from wireshark for both with and without this extra byte, from the same flow.
Can we consider this a quirk of the windows client issuing Query_Info Compounded requests?
Image1 - http://postimg.org/image/th8fubvuz <- As you can see, this is a comounded series of requests and the last requset which is a query_info request *HAS* an extra byte after the file_id.
Image2 - http://postimg.org/image/kkp4adxe7/ <- As you can, this is a compounded series of requests and the last request which is a query_info request, DOES *NOT* HAVE an extra byte after the file_id unlike Image1
Image3- http://postimg.org/image/5w7061vrr/ <- As you can see, this is a single Query_Info request, and we don't have the extra byte here after the file_id.

We worked with cressnet and resolved these questions offline. Here is a summary of resolution.
Regarding the comments on compounded messages with QueryInfo,
this is not specific to QueryInfo.
The receiver’s transport layer delivers the message to the SMB2 layer (server/redirector). The SMB2 PDU starts with its header. The PDU is casted and interpreted based on the SMB2 command. What matters is the message’s structure
itself.
The transport’s (e.g. Nbtss or SMBoverTCP) indicates the length of its payload. Each SMB2 message has a structure which may include some variable length fields. Padding is one element that may complement the message for alignment
purpose. Any extra byte (s) that is not part of the SMB2 message fields would be irrelevant and ignored.
Regarding the comments on ErrorData,
the CHANGE_NOTIFY response packets look valid as documented in the [MS-SMB2] specification. In this particular case, even if the error is not a success code (i.e. STATUS_NOTIFY_ENUM_DIR), the response is an empty CHANGE_NOTIFY
Response, rather than a standard ERROR Response.
The exception cases that are not considered error messages are listed in [MS-SMB2] section 3.3.4.4. When in doubt, please consult the server processing of the specific SMB2 command.
[MS-SMB2] 3.3.4.4 Sending an Error Response
https://msdn.microsoft.com/en-us/library/cc246722.aspx
When the server is responding with a failure to any command sent by the client, the response message MUST be constructed as described here. An error code other than one of the following indicates a failure:
•         STATUS_MORE_PROCESSING_REQUIRED in an SMB2 SESSION_SETUP Response specified in section 2.2.6.
•         STATUS_BUFFER_OVERFLOW in an SMB2 QUERY_INFO Response specified in section 2.2.38.
•         STATUS_BUFFER_OVERFLOW in a FSCTL_PIPE_TRANSCEIVE, FSCTL_PIPE_PEEK or FSCTL_DFS_GET_REFERRALS Response specified in section 2.2.32.<190>
•         STATUS_BUFFER_OVERFLOW in an SMB2 READ Response on a named pipe specified in section 2.2.20.
•         STATUS_INVALID_PARAMETER in an FSCTL_SRV_COPYCHUNK or FSCTL_SRV_COPYCHUNK_WRITE response, when returning an SRV_COPYCHUNK_RESPONSE as described in section 3.3.5.15.6.2.
•         STATUS_NOTIFY_ENUM_DIR in an SMB2 CHANGE_NOTIFY Response specified in section 2.2.36.
[MS-SMB2] 3.3.5.19 Receiving an SMB2 CHANGE_NOTIFY Request
https://msdn.microsoft.com/en-us/library/cc246747.aspx
Change notification processing in the object store MUST be handled as specified in section 3.3.1.3. It is also outlined in [MS-CIFS] section 3.3.5.59.4.
If the server is unable to copy the results into the buffer of the SMB2 CHANGE_NOTIFY Response, then the server MUST construct the response as described below, with an OutputBufferLength of zero, and set the Status in the SMB2
header to STATUS_NOTIFY_ENUM_DIR.
Thanks,
Edgar

Start Servlet with request at startup

I must work with a Servlet application which only start up at the first HTTP request (its init() method does nothing). I mustn't change its code
Is there any method in Tomcat to initalize this servlet when the Servlet Container starts up?
Or is there any method to determine (not from a property file) the port where this context runs in another Servlet's init() method (to generate a request via URLConnection...)
I tried a
RequestDispatcher disp = getServletConfig().getRequestDispatcher('/path/ThatServlet');
disp.forward(?, ?);but I can't find a properly implemented HttpServlet* class to give a request and response objects to the forward() method.

Servlet forward request

In 5.6 do you know how I can forward a request within a servlet that contains query string parameters.
This does not work:
RequestDispatcher rd = request.getRequestDispatcher("/content/geometrixx/en?message=Test");
rd.forward(request, response);

Hi all
That´s right, the OHS was installed with the Fusion Middleware Web Utilities installation and working fine !
The Apex application is online without problems.
Now, my challenge is to implement the security certificate (SSL) on OHS.
I´ve been read many things but I´m a little confused and looking for a specific documentation to do that.
The certificate was generated and got the especific files ( .cer / .crt / .key ) but the problem is how to configure.
Is it necessary to install another software ?
Is wallet manager must be used or just configure some files like ssl.conf ?
Thanks in advance for any help.

Servlet Post Request

hi,
Any body tell me how much data i can send through post. can i send 1 GB, 10GB of data or is ther any limit.
Thanks

From the HTTP 1.1 Spec:The HTTP protocol does not place any a priori limit on the length of
a URI. Servers MUST be able to handle the URI of any resource they
serve, and SHOULD be able to handle URIs of unbounded length if they
provide GET-based forms that could generate such URIs. A server
SHOULD return 414 (Request-URI Too Long) status if a URI is longer
than the server can handle (see section 10.4.15).

Finding Last Successful Request of an Object

Hi Expert's,
Can someone guide me Steps to find the last succesful transport request for a particular object which is succesfully moved from one system to another( i.e, Developement to Production)

Hi,
For this goto T-Code SE03 and navigate to the path "Transport Organizer Tools" -> "Objects in Requests" -> "Search for Objects in Requests/Tasks" now double click on "Search for Objects in Requests/Tasks" give your intended object's technical name. Before giving the technical name select the "Object Type" from the "Object Selection".
once if you execute, it gives the total list of requests in which the given object is involved.
Now check the transport log for all the given requests and go ahead with some manual search process based on your requirement.

Request and Reponse Pipelines for Gateway

I had posted this in SOA Suite forum, but as it is web service related, I hope that I can get an answer on it here:
I understand the meaning of request and response pipelines for client and server Agents but I am not sure I know the same for Gateways.
Suppose that I have service A and service B and both are registered with this gateway.
Does request pipeline executes when service A is called? what about when service A makes a request to service B (calls it) ? (how can I simulate the work of a client agent with gateway here?)
Regards
Farbod

When you register the service A and Service B with the Gateway, the actual URL will now be X and Y
i.e. something like
http://myservice.com/Gateway/SID00234?WSDL
(which could map to /Service/A.asmx?WSDL)
Now when you invoke the service you are actually invoking the URL that teh gateway provided (acting as Reverse Proxy).
In your code, when Service A is making a call to Service B, you actually should change the URL to point to the one in Gateway i.e /SID00235?WSDL)
As far as your question on simulating gateway, let me take a shot at that.
The purpose of Client agent gateway is to set the security headers (UserNametoken, etc) by the Client Application so that when the service receives that you can validate the credentials.
Let me walk through the steps.
Assume you have ServiceA - ServiceA.asmx?WSDL
You register the service in Gateway - new URL will be SID00342?WSDL
You set the policy to validate the credentials that will set by your Client Agent.
Lets assume you want to validate Signature and you will configure policy to validate Signature.
Now at your client application you would use Client Agent to Generate the signature.
Instead of Client Agent what you can do is,
Register the SID00342?WSDL in gateway again
This will generate a new URL - SID00343?WSDL
Apply the Policy here, in the Request pipeline
you can add step to Generate signature
Now when you invoke this new service from the TOols/Test page,
SID00343
You will see in the log, that SID00343 generated Signature
on SID00342 log you will see it accepted messagae with Signature and then will validate the signature.
Hope this helps.
Thanks
Ram

Servlets and forward(request, response)

I have a Servlet that is forwarding the request and response objects to one of two JSP's based upon a parameter in the request object. When opening a browser session and entering my servlet with the first parameter (opCorp=MBSUB) the /criteriaRM.jsp is displayed correctly. However, while still in the same browser session when re-entering the servlet with the parameter changed to opCorp=NEW the second JSP /criteriaPL.jsp is never called correctly - ie the page does not load. However, entering the application with a new browser session works fine (opCorp=NEW loads /criteriaPL.jsp in a brand new browser session) - so I know the second JSP is good and the forward syntax OK. Is there something I am missing? I am using the following code in my servlet
               if (request.getParameter("opCorp").compareTo("MBSUB")==0) {
                    getServletConfig().getServletContext().getRequestDispatcher("/criteriaRM.jsp").forward(request, response);
               } else {
                    getServletConfig().getServletContext().getRequestDispatcher("/criteriaPL.jsp").forward(request, response);
Any ideas would be much appreciated. Thanks!!

Ok, your jsp isn't loded but what else does happen then ? Any exception thrown ? Page not found message ?...

How to 'tunnel' requests/response with servlet?

Hallo!
I have the following problem.
Tomcat is used as ServletEngine. Here should work a servlet for authorization. The web application resides on another webserver.
After authorization all request go to Tomcat where a servlet should get (via HTTP) the HTML-pages from the other webserver and sends them to the client. The customer wants to act the Tomcat as Server to the client and as client to the other webserver. For me it seems to be some kind of proxy functionality.
How can I achieve this?
Kind regards
Jochen

Hi,
I am currently writing almost the same thing. And I have a partial success with something like ProxyServlet. What it does:
1. creates a URL object
2. creates HttpURLConnection through the URL
3. copies servlet's request parameters to the HttpURLConnection's request
4. copies the HttpURLConnection's response to the servlet's response
It works, but it is very - very slow.
I am currently struggling with the Keep-Alive feature in HTTP 1.1 that the remote server sends. If I copy that header onto the response, the client sends another request to the same channel, that is mean while broken - the servet is used only by one to one.
I am trying to find something like URL Connection pool, but still I am not successful. I am going to try not to trasfer the Keep-Alive headers to the client - perhaps this sort of downgrading Http 1.1 to 1.0 will limit the timeout delays ...
Did you succeed in your work ?
Ales
