Main servlet controller which handle every dynamic request

          Hello
          first of all, I experiments on weblogic 6 sp1
          I'd like to set in my webapplication a central servlet which will handle every
          dynamic call(every servlet). But I would like that it does not handle the static
          files (.gif, .pdf...)
          I used the <servlet-mapping> facilities in my web.xml file with the following
          value <url-pattern>/</url-pattern>, but in that case my servlet receive every
          request.
          In fact if my application context is "webapp", I would like to set a mecanism
          which route the following URL to my servlet :
          http://host:port/webapp
          http://host:port/webapp/whatever
          http://host:port/webapp/whatever?param1=value1
          but not these one
          http://host:port/webapp/file.gif
          http://host:port/webapp/file.pdf
          Thank you for your help
          

You do not remove exceptions. You fix the cause of the exception.
You said, it is caused by the Class#forName() call on the MySQL JDBC driver class? Is it a ClassNotFoundException? If so, then put the MySQL JDBC driver class in the classpath. It is available in the MySQL Connector/J JAR file which you can download from the manfacturer's website.

  • Implementing session handling in servlet controller

    how to implementing session handling in servlet controller.
    instead of writing isNew() in every jsp page i wanted to write in my central controller ,where each request is passing through controller. can any body give me the solution

    i tried it it is failed because first time the request is coming to the controller.it checks for new since of it is a first request it is forwarded to the login page.how to avoid or skip the condition checking when the request is first time.

  • Servlets handle multiple, concurrent requests

    Hi, folks. Could someone give me a basic idea of how Servlets handle multiple, concurrent requests which are sent from user's web browser, or possibly, point me some useful web links, tutorials. Let me take a example to make sure that i have explained the question clearly: let's say there is a website that does air ticket booking service. Suppose there is a spare seat exists for a particular flight. There are two users logon to the website and they are both looking for this particular seat. So, once these user's HTML form requests are sent to server, how do i implement my servlet to handle these requests properly, in another words, make sure this seat is only allowed booked by a single user. thanks in advance.

    This acturally raises me a another question which i
    still have some uncertainties. In another assignment i
    did last semester, that was we had multiple users
    using our database and accessing, retirving and
    updating database by using jdbc. And what i did was
    let every user call a particular method within a
    javabean for setting up database connection, then goes
    for the specific that needs to be dealt with. So, what
    i am wondering now is that can i possibly having a
    different approach, like setting up only a single
    connection(ie. a public Connection objec) which being
    exist all the time so that all request can get
    connection by calling this object's relevant method.
    Hope i explained it clearly.
    If I understand you correctly, then you would have to make the methods of this Connecting Object synchronized so that there was only ever one connection to the database at any one time.
    If a database is transactional, that means it has attempted to deal with the problem of multiple connections and statements being executed at the same time on the same data. If you have one single Connecting Object then you don't have to worry about transactions, but you do need to make sure that there aren't multiple threads running, each trying to use your Connecting Object.
    The synchronized keyword makes sure only one thread can use the synchronized method at any one time.

  • Session replication at every http request

    Hi everybody
    I'm trying to use ZKoss Framework (www.zkoss.org) to develop a
    web application and deploy it in a Clustered WebLogic Server.
    The main issue I'm facing is that the "state" of the visual interface
    is stored inside the http session, and so, when node that handle
    the http request changes, the state is resetted and then the page changes,
    even if there was no user intervention.
    So I need to replicate the whole session at every http request,
    to prevent strange behaviours when the request handler node's changes.
    Do you know some settings that will force WebLogic Server to replicate the whole
    session at every http request?
    Thanks in advance.
    bye.

    Hi Marco,
    Yes, You are right But You NEED NOT to put setAttribute("key","value")...code in all your JSPs. because if the Attribute data of Session is changed then Automatically it will be replicated (only the Changed Data and not the Data which is unchanged). Even we need not to worry about replicating the Unchanged Data Again...And WebLogic will take care of ChangedData by itself. There is no other alternate solution available in weblogic to do this...Even no such similar Element available in Deployment descriptors as well.

    Programming Considerations for Clustered Servlets and JSPs
    This section highlights key programming constraints and recommendations for servlets and JSPs that you will deploy in a clustered environment.
    Session Data Must Be Serializable
    To support in-memory replication of HTTP session states, all servlet and JSP session data must be serializable.
    Note:     Serialization is the process of converting a complex data structure, such as a parallel arrangement of data (in which a number of bits are transmitted at a time along parallel channels) into a serial form (in which one bit at a time is transmitted); a serial interface provides this conversion to enable data transmission.
    Every field in an object must be serializable or transient in order for the object to be considered serializable. If the servlet or JSP uses a combination of serializable and non-serializable objects, WebLogic Server does not replicate the session state of the non-serializable objects.
    Use setAttribute to Change Session State
    In an HTTP servlet that implements javax.servlet.http.HttpSession, use HttpSession.setAttribute (which replaces the deprecated putValue) to change attributes in a session object. If you set attributes in a session object with setAttribute, the object and its attributes are replicated in a cluster using in-memory replication. If you use other set methods to change objects within a session, WebLogic Server does not replicate those changes. Every time a change is made to an object that is in the session, setAttribute() should be called to update that object across the cluster.
    Likewise, use removeAttribute (which, in turn, replaces the deprecated removeValue) to remove an attribute from a session object.
    Note:     Use of the deprecated putValue and removeValue methods will also cause session attributes to be replicated.     
    Thanks

    Java programs are run by a virtual machine which is running in userland. They don't "mess" with the kernel.
    OTOH, each userland program interacts with the kernel through system calls, signals, pageing activity, ...
    My guess is that it's either broken hardware, or a fault in the linux kernel.
    Is the crash reproducible? Does ist always crash with the same error message, at the same "eip" location?
    If the crashes are sporadic and non deterministic, with different error messages each time, then I'd say it's
    a hardware problem. Otherwise, it could be a linux kernel software problem.

  • How to print out the exception caught in the servlet controller to JSP?

    May I know how to print the Exception caught and the stacktrace thing? What i try to do this in the databaseErrata.jsp code was not given me any answer. Instead, causing a number of errors.
    Below are my servlet controller code and databaseErrata.jsp code.

    You're missing a closing curly bracket in the JSP page.
    Also, this will only print the exception message. I would recommend passing on the whole Exception object.
    ie request.setAttribute("theException", ex);
    That way you have the exception object to print the stacktrace from.
    However, you are doing this manually. The container can handle this stuff for you if you so wish.
    Check the documentation on error pages. You are able to set up an error page in the web.xml, that all exceptions/errors get directed to.
    something like:
    <error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/errorPages/debugError.jsp</location>
    </error-page>
    You then write the JSP page something like this
    <%@ page language="java" %>
    <%@ page isErrorPage="true" %>
    <%@ page import="java.util.*, java.io.*" %>
    <h1>Programming error <BR> FOR DEBUGGING PURPOSES ONLY</h1>
    <p>This page is only for debugging purposes.  Should not be deployed to live environment.</p>
    <p>Details of the error are as follows:</p>
    <table border = 1 width=200>
    <tr><td valign=top><strong>Error :</strong></td><td><%=exception.getMessage()%></td></tr>
    <tr><td valign=top width='80%'><strong>Trace :</strong></td><td><pre><% exception.printStackTrace(new PrintWriter(out));%></pre></td></tr>
    </table>

  • RE: [SunONE-JATO] handle...Request() - in different TiledView?

    I need probably to reorder Parent-Child relationships,
    I have now
    - ViewBean
    ---MenuItemsTiledView.class
    ---OrderCacheTiledView.class
    ---Button.class (append)
    I will try to have
    - ViewBean
    ---MenuItemsTiledView.class
    ------OrderCacheTiledView.class
    ---------Button.class (append)
    And I will have to change:
    <jato:tiledView name="MenuItems"
    <jato:tiledView name="OrderCache"
    <go method="post" href="<%=response.encodeURL
    ("../member/MenuItems") %>">
    <postfield name="MenuItems.append" value=""/>
    <postfield name="MenuItems.menuItemId"
    value="<jato:getDisplayFieldValue
    name='MenuItemId'/>" />
    </go>
    I think it is strict rule to have the same parent-child relationships in
    JSP like as in classes
    May I have more freedom like as with <jato:text name="...">, where name
    could be relative (to parent, to container), absolute?

    Subject: [SunONE-JATO] handle...Request() - in different TiledView?
    Hello,
    I use ViewBean, and two child TiledViews (WML sample).
    <jato:tiledView name="TiledView1"
    type="mobiledb.member.MenuItemsTiledView">
    <go method="post" href="<%=
    response.encodeURL("../member/MenuItems") %>">
    <postfield name="MenuItems.append" value=""/>
    <postfield name="MenuItems.menuItemId"
    value="<jato:getDisplayFieldValue name='MenuItemId'/>" />
    </go>
    I think, "handleAppendRequest()" will work within TiledView1 (I didn't
    try yet, I have this handler in ViewBean).
    But, logically, better place for it is TiledView2 which contains cached
    appended records...
    I can have handler in ViewBean redirecting into TiledView2 of course,
    What is the best way?
    Thanks,
    Fuad

    OK, I solved it (for WML),
    If I use "virtual buttons" on JSP page (within <jato:tiledView.../>
    tag), and this buttons are child of MyTiledView class (which is child of
    MyViewBean), I can use
    <postfield name="MyJspPage.MyTiledView.Append[2]" value=""/>
    for emulation of button.
    I don't use MyViewBean.MyTiledView.Append[2]!
    Next step: I have to understand what to do with index in
    MyTiledView.handleAppendRequest... Code seems harder than putting Button
    and Handler in main MyViewBean...

  • Servlet controller unavailable

    I am getting the error as follows in my web application.Can anybody tell me the reason.Thanks in advance
    HTTP Status 503 - Servlet controller is currently unavailable
    type Status report
    message Servlet controller is currently unavailable
    description The requested service (Servlet controller is currently unavailable) is not currently available.
    Apache Tomcat/4.1.27

    Are you sure you have mentioned the servlet in the web.xml file.
    This web.xml file lets Tomcat know which servlets exist and where to look for it.
    So, you should have the following tags in the web.xml file of your web application.
    <servlet>
    <servlet-name>MopoController</servlet-name>
    <servlet-class>org.gertcuppens.controller.MopoController</servlet-class>

    <url-pattern>/MOPO</url-pattern>

  • Change upload file name with com.oreilly.servlet.MultipartRequest to handle the file upload

    1. when use com.oreilly.servlet.MultipartRequest to handle the file upload, can I change the upload file name .
    2. how com.oreilly.servlet.MultipartReques handle file upload? do it change to byte ?
    what  different?  if I use the following method?
       File uploadedFile = (File) mp.getFile("filename");
                   FileOutputStream fos = new FileOutputStream(filename);
                    byte[] uploadedFileBuf = new byte[(int) uploadedFile.length()];
                   fos.write(data);
                 fos.close();

    My questions are
    1) when use oreilly package to do file upload , it looks like i line of code is enough to store the upload file in the
    file direction.
    MultipartRequest multi =
            new MultipartRequest(request, dirName, 10*1024*1024); // 10MB
    why some example still use FileOutputStream?
    outs = new FileOutputStream(UPLOADDIR+fileName); 
        filePart.writeTo(outs); 
       outs.flush(); 
      outs.close();
    2) can I rename the file name when I use oreilly package?

  • A new socket for every http-request?

    Do I have to make a new socket for every http-request? The code below doesn't work because it is two requests in a row. The first GET works, but the second doesn't. I thought that the purpose of a socket is that you set it up once and then you should be able to do arbitrary communication between the two peers. Maybe that is just the case with sockets only but not if you use sockets to perform http.
    Thank you for your answers! Nice greetings from Austria (not Australia)!
    Stefan :)
    package httptest;
    import javax.net.ssl.*;
    import java.io.*;
    import java.net.*;
    public class Conn2 {
        private PrintWriter out;
        private BufferedReader in;
        private Socket socket;
        public Conn2()
            try {
             socket = new Socket("www.google.at", 80);
             out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())));         
             if (out.checkError())
              System.out.println("SSLSocketClient:  java.io.PrintWriter error");
             in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                System.out.println("Connect erfolgreich.");
         } catch (Exception e) {
             System.err.println(e);
        public void test()
            String inputLine;
            // 1. GET
            out.println("GET / HTTP/1.0");
         out.println();
         out.flush();
         try
                while ((inputLine = in.readLine()) != null)
                    System.out.println(inputLine);
            catch(IOException e)
                System.err.println(e);
            // 2. GET
            out.println("GET / HTTP/1.0");
         out.println();
         out.flush();
            try
                while ((inputLine = in.readLine()) != null)
                    System.out.println(inputLine);
            catch(IOException e)
                System.err.println(e);
    }

    Normally in the HTTP protocol, the server will close the connection after every request. So after you do the first GET, the server sends you the result and closes the connection. You have to open a new connection for the second GET.
    You can set specific headers to keep the connection open, which makes things faster if you have to do multiple GET's quickly after another. Lookup the specification of the HTTP protocol on http://www.ietf.org/
    Maybe it's easier to use a HTTP client library like Apache's HTTPClient: http://jakarta.apache.org/commons/httpclient/ so that you don't have to implement all the difficulties of the HTTP protocol yourself.

  • Peer not authenticated exception on every SSL request

    I'm using VeriSign-issued SSL certificates and WebLogic appears to be working fine with them.  No browser issues, no server errors -- unless I enable SSL debugging.  We were investigating an earlier issue (See: Extremely slow Apache 2.2-WebLogic 12c proxy behavior when using SSL) and we noticed that with every SSL request, we see the following error in the weblogic-server.log:
    ####<Nov 18, 2013 3:46:52 PM CST> <Debug> <SecuritySSL> <zlxv8131.vci.att.com> <CASWEBAdminServer> <ExecuteThread: '1' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1384811212294> <BEA-000000> <Exception processing certificates: peer not authenticated

    We continue to see this for every HTTPS request -- every initial GET for the page, and all GETs for associated scripts, images, stylesheets, etc. 
    This is WebLogic 12.1.1.0 on Red Hat Enterprise Linux 6.  I have the following startup options set:
    -Dweblogic.StdoutDebugEnabled=true
    -Dssl.debug=true
    -Dweblogic.security.SSL.nojce=true
    -Dweblogic.security.SSL.ignoreHostnameVerification=true
    -Dweblogic.security.SSL.enforceConstraints=off
    Is this actually a concern, given that we only see it when extended SSL debugging is enabled?  When I Google (or search the Oracle forums) for this error, I find only my earlier posting, or folks dealing with self-signed certificates.  Surely this is a more common issue.  We are experiencing it on several different WebLogic installations on different servers.  Exact same error on every SSL request, yet the page renders fine and there are no processing errors or delays -- just the debugging error above.
    Any assistance would be much appreciated!

  • Flash Media Player which handles bitrate switching for live streams?

    Hello.  I've got a very short timescale to find a solution for a way to display livestreams with bitrate switching. Does anyone
    know of any opensource players which can do this effectively?  Or do the inbuilt components in CS4 deal with this ok?

    Thanks,I have read that article.  Based on that article the NetStreamInfo.maxBytesPerSecond is not an accurate measurement to base dynamic switching on. This seems to be the basis of the bitrate switching in both the longtail player, and the adobe examples that I have tried.   That article suggests using the dropped frames property, in conjunciton with bufferlength to determine if switching is neccessary.  Unfortunately I can't seem to find a player online which handles this successfully.  That being said, I can't believe I'm the only person trying to implement dynamic bitrate switching for live streams so surely there are some players out there which can do this successfully?  If anyone knows of any code available which does this successfully I would appreciate knowing where!  The examples provided by Adobe https://www.adobe.com/cfusion/entitlement/index.cfm?e=fms35 unfortunately don't work either.

  • Which process/application is requesting 'elevated privileges'?

    Every hour or so, I get a pop-up screen that asks for an administrator password and tells me:
    "Elevated privileges are required in order to complete installation. Type an administrator's name and password to allow this.", see screenshot below.
    The pop-up is not embedded in a full application, so I cannot see in the upper left corner which application is responsible. Needless to say, I would like to understand which application/process is requesting this before providing these details. Restarting my laptop does not resolve this issue. Removing all Login Items and restarting my laptop does not resolve it either. It keeps coming back.
    How can I find out which process/application is responsible? How can I remove this issue?
    Thank you for your help.

    Sharp one, thanks...!
    I just upgraded Picasa (had not done that in a while) via Google Software Update and indeed as part of this process I was presented an identical screen to provide credentials.
    I'll keep an extra look at these applications. If this problem keeps recurring I will try removing them. Hypothesis to explore that this popup only comes up if a specific Google application is not on the latest version.

  • How to build a wsdl which can cater dynamically to number of attachments

    We have a WebService client that calls a Webservice on the Server.
    When the client calls the webservice , it passes the SOAP message(Header,Body & MIME attachments)and these attachments vary in number based on different business requirements.
    We know how to build WSDL for server with static number of attachments,but no clue on how to build a wsdl which can cater dynamically to number of attachments comming from client request.
    - thanks in advance

    Hello,
    We may have multiple approaches here depending of :
    - which version of the product you are using
    - what are your clients in term of stack, and API they are willing to use
    - which encoding did you use for your WS (swa, swaRef or dime)
    So for my answer I am documenting how to do it on OracleAS 10gR3 (10.1.3), using swaRef approach.
    The easiest way is to exchange array of binary data and describle that in the WSDL, so in my case the WSDL element that is used will look like that:
    <element name="filesResponseElement">
    <complexType>
    <sequence>
    <element name="result" type="ns1:swaRef" minOccurs="0" maxOccurs="unbounded"/>
    </sequence>
    </complexType>
    </element>
    This will generate from the Java code an array of AttachmentPart[].

  • I installed all creative suite /cloud products on my main hard drive which has just failed. I can't

    I installed all creative suite /cloud products on my main hard drive which has just failed. I can't open the apps on that drive. How can I deauthorize them when the drive is damaged beyond repair and unresponsive?

    Kay5000 you are posting in a pubic forum.
    As Ankit stated please try installing and activating Creative Cloud on your replacement computer/hard drive.  If you have reached your maximum activation count then you will be prompted to deactivate all your activations.  This will then allow you to activate on the replacement computer/hard drive.
    For Creative Suite 6 I would recommend that you try installing as well.  If you receive a message that you have exceeded your amount of allowable activations then please contact our support team directly.  Our support team will be able to increase your activation count and allow you to install on the replacement computer/hard drive.  You can contact our chat support at http://adobe.ly/yxj0t6 to make this request.
