Invoking servlet at Click of a JButton.

I have a swing application running fine.I now want to introduce a functionality for opening a new popup window on the click of a JButton in my appln., similar to window.open() method in javascript.When I click a JButton , a servlet gets invoked, talks to the database and gives some results. I want these results to be displayed in the new popup window.
Thks.

if you have an applet then try this:
URL pageURL = null;
try {
pageURL = new URL("your servlet path");
} catch (Exception e) {
System.out.println(e);
return;
getAppletContext().showDocument(pageURL, "_blank");
for an application you need to retrieve the servlet result and display it in a HTML parser container.

  • Invoking servlet from mDB

    Hi all;
    this is the process.
    1. Servlet received / creates msg.
    2. Servlet Enqueues Msg on JMS queue.
    3. MDB dequeues.
    -- processes against DB
    -- composes respoonse.
    4. mdb invokes servlet with response.
    servlet need not maintain state.
    State information can be passed in Msg (Query and Response)
    I was just wanting to find out if this possible in oc4j.
    apparently, there is a process in weblogic 6.1 to support this.
    Any help is appreciated.
    thanks.
    jayant

    I would assume that you would need to do a "createSipApplicationSession" on your sip factory and then get the ID from there.
    Then create a request from your session and send it.
    Wouldn't you want each outgoing call to be associated with a different sip app session?

  • How to configure IIS webserver with weblogic so that I can invoke servlets without the .wlforward extension

    How to configure IIS webserver with weblogic so that I can
    invoke servlets without the .wlforward extension
    As per the documentation iisforward.dll is registered as a filter and .wlforward
    has also been
    included as a special file type. However this requires me to key-in ".wlforward"

    Thanks,
    Rishi

    I am able to invoke the servlet without the wlforward extension now.
    However, now I am required to add /weblogic before the servlet
    name otherwise it does not execute the pathtrim property.
    I have tried with the pathprepend thing also.
    Can we get rid of the /weblogic part also. I just want to execute
    my servlet as http://iis/myServlet.
    Your help in this regard is greatly appreciated...

    Thanks for the reply Kumar.
    I did follow the instructions as given in the Weblogic documentation
    The documentation said to add iisforward.dll as a filter service
    and register .wlforward as a special
    file type to be handled by iisproxy.dll. For this,
    while configuring the IIS server in the Home Directory tab
    I added an extension ".wlforward" and the executable as
    iisproxy.dll. Is this the way it should have been done...
    I also modified the iisproxy.ini file as per the documentation.
    I have added the WLForwardPath property and set it to /weblogic.
    My server works fine when I give the url as
    http://iis/myServlet.wlforward
    but it does not work for
    http://iis/myServlet and this is the way i'd want it to work.
    Please tell me if I am missing something on the configuration part
    and if there is something special that needs to be done. I shall
    be grateful to you.

  • Invoker servlet

    Hi,
    I am interested in knowing why we should avoid invoker servlets?
    what are short comings of invoker servlet?
    ( Yes for invoker servlets completer path up to servlet is to be given)
    Thanks

    The Invoker servlet is a built int servlet mapped such that allows you to invoke any servlet by using the URL: /servletPackage/servletClassName. While this is good to get started and to know, you should never use it in a production environment.
    If you give password protected access to a folder, say Employees and map a servlet to /Employees/MyServlet, the servlet is also protected. Only people with the authorized username/password combinations can run the servlet. But if you allow the default mapping with the Invoker servlet, then the same servlet will also be accessible to everyone as /servlet/MyServlet in which case your authorization fails and everyone has access to your servlet's functionality, potentially modifying data etc.
    This is only the authorization aspect. Other than this, the Invoker servlet makes it hard for you to hide your actual package/ classnames. Other features like init parameters and filters are also not possible in this case.
    This is why you should NOT use the Invoker servlet. Even the Tomcat FAQ says you should not.
    Read more here:
    [1] http://faq.javaranch.com/view?InvokerServlet

  • 404 error while invoking servlet in weblogic 6.0

              Hi,
              When I try to invoke a servlet from weblogic 6.0, I am getting
              404 error. I have copied the HelloWorldServlet class into defaultWebAppl_Server/WEB_INF/CLASSES
              directory and when I invoke the HelloWorldservlet, its giving file
              not found(404) error. I am doing exactly what has been given in
              the "quick start to servlets" in weblogic 6.0. I am using Windows
              NT.
              I have also another problem when I use java utils.dbping to test
              the connection to my oracle8.1.8, its giving licence file not found.
              Could some one help me out from this.
              Thanks in advance,
              Ramu
              

              Hi kumar,
              I have been keep trying to solve that. After some time Suddenly
              "Error 404" disappeared and instead "Error 500" came. Okay kumar,
              here is what I am doing...
              I have installed weblogic6.0(eval), oracle 8.1.6 on Windows NT4.0.
              I have installed oracle Enterprise edition from CD "ORACLE 8.1.6
              for NT".
              I installed the weblogic under D: drive.
              I did class path settings as given in documentation. But Iam not
              sure whether I need to do any other class path settings.
              I was able to run pet store application given in weblogic server.
              I went to "quick start" section and ran HelloWorld.jsp page from
              "DefaultWebApp_myServer" directory.
              I was not able to run servlet program as per given in the "quick
              start". I am getting
              "Error 500---Internal server error"
              The server encountered an unexpected condition which prevented
              it from fulfilling the request"
              I have modified the web.xml under WEB-INF of DefaultWebApp_myServer
              as per given in the quick start.
              Here is the quick start link For you reference(as what I talking
              about)
              http://edocs.beasys.com/wls/docs60/quickstart/quick_start.html
              In the web.xml, I have given <servlet-class> as just HelloWorldServlet,
              since I directly copied the file from some other examples directory.
              But still I am getting 500 error.
              Here is the url that I am invoking...Http://ramup:7001/quickStartServlet
              Coming to your oracle connection test, I did exactly what you said.
              kumar, I have executed the command
              "D:\bea\wlserver6.0\config\mydomain>java -classpath %classpath%;D:\bea
              utils.dbping ORACLE
              >scott tiger TestDB"
              Where TestDB is the database that I have created while installing,
              but I am not aware of the instance you said.
              Here is what I got after executing the command.
              --------*******-------Pasting the ms-dos command results----**-
              // This mode is superior, especially in serverside classes because
              // it avoids DriverManager calls are class synchronized, and will
              // bottleneck any other JDBC in the server, even already-running
              // connections, because all JDBC drivers use DriverManager.println()
              // to log info and exceptions, and that call is also class synchronized.
              // For repeated connecting, a single driver instance can be re-used.
              **** or ****
              Class.forName("weblogic.jdbc.oci.Driver").newInstance();
              java.sql.Connection conn =
              DriverManager.getConnection("jdbc:weblogic:oracle:TestDB", "scott",
              "tiger")
              **** or ****
              java.util.Properties props = new java.util.Properties();
              props.put("user", "scott");
              props.put("password", "tiger");

              Class.forName("weblogic.jdbc.oci.Driver").newInstance();
              java.sql.Connection conn =
              DriverManager.getConnection("jdbc:weblogic:oracle", props);
              D:\bea\wlserver6.0\config\mydomain>
              --------*******-------Pasting the ms-dos command results----**-
              I think I have connection to database, thanks for your suggestion.
              Kumar, I have not seen weblogic.properties file any where in D:\bea
              directory.
              Kumar, if you have some time can you jot down the classpath settings
              and path settings for executing SERVLETS/EJB programs.
              Thanks for helping me out..,

  • Error 404 invoking servlet in tomcat

    OK Im new in this and I have searched the forums and do most of the answers but I cant make my servlet to work. So here is how I have my structure
    MEDEX \ WEB-INF -> all JSP files
    MEDEX \ WEB-INF \ classes -> all CLASS files
    MEDEX \ WEB-INF \ servlet -> SERVLET CLASS FILE

  • Error in invoking servlet from JSP

    Hi - again!
    after being thoroughly reprimanded for posting on the wrong board, and hence seeing the error in my ways, all help greatly appreciated....
    I have read elsewhere that it is possible to call a servlet (which produces HTML) from within a JSP, thus keeping a nice clean MVC paradigm and making it easier for non-java people to design the front-end.
    I am having difficulty getting it to work and any help is much appreciated:

  • Unable to invoke Servlet Directly in address bar in Weblogic10.3

    Hi,
    I am trying to invoke the servlet directly in the address bar as below

    Error 404--Not Found

    This works fine on Weblogic 8.3.
    Please Help here.

    Hard to tell exactly.
    I note that your JSP page does a "POST" submit, whereas when you enter the direct URL of the servlet on the address bar, it'll result in a "GET" request.
    <form method="post" action = "http://localhost:7004/servlet/loginToApp">
    I don't know what error WLS will return if the servlet can't handle a GET, but it may be something to look at.
    Do you have a doGet() method in your servlet code?
