Dynamic JSP's includes from JSF Java Beans

Hi!
I�m David from Barcelona.I'm testing different JSF components.
I'm working with MyFaces components, with Tabs, binding the component like this to create sub tabs dynamically:
<t:panelTabbedPane binding="#{editorPanelBean.pane}"/>
Now, in the bean, I use the Application class to create
my pane and child tabs:
UIComponent pane = app.createComponent(TABBEDPANE);
UIComponent childtab = app.createComponent(PANELTAB);
HtmlPanelTab tab = (HtmlPanelTab) childtab;
I want to start adding contents to my child tabs.
Am I locked into doing it programmatically or is it possible to somehow refer back to a JSP page
with an include to generate the contents of each tab child?
I can do it without binding the panelTabbedPane component, but the problem it's when I construct the component with a binding, then the include JSP doesn't work. I have tried with a Verbatim and HtmlOutputText but no results, like this:
HtmlTabItem aHtmlTabItem = (HtmlTabItem) application.createComponent(HtmlTabItem.COMPONENT_TYPE);
aHtmlTabItem.setValue(valor);
aHtmlTabItem.setId(viewRoot.createUniqueId());
UIOutput verbatim1 = (UIOutput) application.createComponent("javax.faces.Output");
//verbatim1.setValue("<f:subview id=\""+viewRoot.createUniqueId()+"\"><jsp:include page=\"ficha_paciente_tab2.jsp\" flush=\"false\"/></f:subview>");
verbatim1.setValue("<%@ include file=\"ficha_paciente_tab2.jsp\" %>");
verbatim1.getAttributes().put("escape", Boolean.FALSE);
verbatim1.setId(viewRoot.createUniqueId());
aHtmlTabItem.getChildren().add(verbatim1);
How can I include dynamically from my bean a JSP page with the HTMlL design of each tab and anything I want to ?
Any help would be great !
Thanks!

1. username and password should be simple String properties, don't make it any more difficult than it needs to be.
2. if (result == "success")
Oh dear, Java 101 mistake. You want to use result.equals("success") to make that work.
Another observation: you may want to move all the database code to a separate class. If you put database logic in seperate classes with specific methods (login(), logout(), getAllUsers(), etc.) you not only make your code more readable but you make it possible to re-use those methods in different parts of your code.

    No you haven't, because
    Caused by: java.lang.NoClassDefFoundError: org.example.www.Sample_PortType a relevant class can still not be found and Java really is not going to lie to you; this class is not on your application's classpath so it is either missing or put in the wrong place. Note that missing classes can be caused by you forgetting to properly redeploying your application - its usually something silly like that. Figure out what you did wrong and correct your mistake.
    The fact that you have to mention that you "setup the classpath" is questionable; in web applications you don't touch the classpath at all. So what exactly did you do?

  • How to get an XML string from a Java Bean without wrting to a file first ?

    I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
    But how can I get an XML string of a Java Bean without writing to a file first ?
    For instance :
    My_Class A_Class = new My_Class("a",1,2,"Z", ...);
    String XML_String_Of_The_Class = an XML representation of A_Class ?
    Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?

    I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
    import java.io.*;

      private URL servlet;
      // the URL of the servlet to send messages to
      public Servlet_Message(URL servlet) { this.servlet=servlet; }
      public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
      // Send the request. Return the input stream with the response if the request succeeds.
      // @param args the arguments to send to the servlet
      // @param method GET or POST
      // @exception IOException if error sending request
      // @return the response from the servlet to this message
      public String sendMessage(Properties args,int method) throws IOException
        String Input_Line;
        StringBuffer Result_Buf=new StringBuffer();
        // Set this up any way you want -- POST can be used for all calls, but request headers
        // cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
        if (method==GET)
          URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
          BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
          while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
        else     
          URLConnection conn=servlet.openConnection();
          conn.setDoInput(true);
          conn.setDoOutput(true);           
          conn.setUseCaches(false);
          // Work around a Netscape bug
          conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
          // POST the request data (html form encoded)
          DataOutputStream out=new DataOutputStream(conn.getOutputStream());
          if (args!=null && args.size()>0)
            out.writeBytes(toEncodedString(args));
    //        System.out.println("ServletMessage args: "+args);

        return Result_Buf.toString();               // Read the POST response data   
      // Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
      // @return the URLEncoded string with name=value pairs
      public String toEncodedString(Properties args)
        StringBuffer sb=new StringBuffer();
        if (args!=null)
          String sep="";
          Enumeration names=args.propertyNames();
          while (names.hasMoreElements())
            String name=(String)names.nextElement();
            try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
    //        try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
            catch (UnsupportedEncodingException e) { System.out.println(e); }
            sep="&";
        return sb.toString();
    }As shown above the servlet need to encode a string.
    Now my question becomes :
    <1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
    <2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

  • How to include PJC and Java Beans in forms

    I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
    oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
    don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
    Please solve this matter
    Thanking you,

  • Accessing an URL from Forms Java Bean

    Dear Oracle Gurus,
    Please help me
    I have an Oracle Application Server 10g Rel1 in production. I have oracle forms running with a java bean. I am passing an URL to this java bean to fetch and display an image.
    This url belongs to another web server (IIS server running a ASP.net application). If i call this url in internet explorer window it is displaying the image. If the same URL if i am calling from forms applet it is not working. When i checked in the java console by setting up trace level to 5 no error message.
    I have checked in the midtier/j2ee/home/log/home_default_island_1 folder in the log file no error messages. I have setup the internet explorer --> internet options --> security --> custom level --> miscellaneous --> access data across domain --> enable.
    Please give me a solution.
    Best Regards

    Hello,
    I don't know how we can help you, because you use a Java Bean and did not tell us anything about this bean. A bean is like a "black box", so we cannot give you any help at all without the code.

  • Redirect from JSF backing bean to another application

    Hi,
    I need to open another (non-JSF) application in a new window from the backing bean of my JSF application.
    My JSF application is in frames. - heading, menu, content.
    I've a commandlink in the menu frame.
    I tried with
    FacesContext.getCurrentInstance().getExternalContext().redirect(loginUrl);
    This is opening in the menu frame itself.
    I tried using target="new" , but no result.
    I also need to pass the userId to the external application.
    Any ideas?
    ~Thanks.

    Thanks.
    Yes, GET works. I used a <h:outputLink and used target="new" and
    window.open("url?userId=someId")
    But i donot want to pass userid in GET in the url, since that is a sensitive information.
    Please let me know if there's any other way.
    Thanks,

    Relax.
    Okay, so you create a GenerateUrlBean in your JSP and call the getUrl() method. When does the value that getUrl() is supposed return get set?

  • Accessing RFCs and BAPIs from enterprise java beans

    Hello folks,
         my question is concerning comunication between EJBs and RFCs. I want to develop a simple session bean that connects to a R/3 back-end, calls a RFC then returns some data, let's say, an example of this could be a list of employees from BAPI_EMPLOYEE_GETDATA.
         Ok, by using a web dynpro and adaptive RFC my works could be very very easy, but I'd like to test this way: session (stateless) EJB -> RFC. Can I:
    *     use JCO.ClientService with a non-portal SAP WAS?
    *     use embedded JRA (SAP Library stated "The SAP JRA is an add-on for the SAP JCo. If you use      the SAP Web AS, the SAP JRA is installed automatically with the SAP JCo.", but I found      nothing so in Connector Container Service ...)
    *     install and configure JRA by myself?
    I'm working on a SAP WAS 6.40 Sneak Preview (Java only), and finding a path for easily integrate SAP WAS developed ejbs and external business system. SAP Library suggest to "obtain the JCo connection through the connection framework": is it related to JRA, JCA and SAP Resource Adapter?

  • Using Java Bean in JSP to show database record

    I have links in my Tomcat container that if someone clicks on a specific link it should go to a Record page (Show.jsp) with all the values associated with a record from a database.
    For example if someone clicks on a specific link like this:
    LinkExample
    it would take you to a jsp with database info for someone named Jones and show you his info:
    Lastname = Jones
    Firstname = Mike
    City = San Diego
    I would like to do this using a Java helper class and bean so I dont have any database connection or Java code in my JSP.
    I created Java class file that has Database connection that works with a Java bean. I just dont know how to get the Show.jsp to work with the Java Bean and Java helper class file.
    Here is what I have for Show.jsp and this is the part I have been working on the longest but cant get it to work because it doesnt seem to work with the database:<jsp:useBean id="user" class="num.UserDB"/>
    //do I call getUser(lastname) here and if so how?
    <jsp:setProperty name="user" property="*"/>
    Last Name: <jsp:getProperty name="user" property="lastname"/><BR>
    First Name: <jsp:getProperty name="user" property="firstname"/><BR>
    City: <jsp:getProperty name="user" property="city"/><BR>My Java Helper class that compiles and connects to database:
    package num;
    import java.io.*;
    import java.sql.*;
    import java.util.*;
    import num.User;
    public class UserDB
    public User getUser(String lastname)
    User user = new User();     
            try          
         Class.forName...//database connection stuff here
        ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
         if(results.next() == true)
         results.next();
         user.setLastname(results.getString("lastname"));
         user.setFirstname(results.getString("firstname"));
            user.setFirstname(results.getString("city"));
         catch(Exception e)          
                   System.out.println("Exception...");               
       return user;
    }My Java Bean that compiles here:
    package num;
    public class User
      private String firstname;
      private String lastname;
    private String city;
      public User()
         //no arg constructor
      public User(String firstname, String lastname, String city)
           this.lastname = lastname;
              this.firstname = firstname;
              this.city = city;
      public String getLastname()
              return lastname;
      public void setLastname(String lastname)
         this.lastname = lastname;
      //more bean methods for all fields here
     

    Sorry if I wasnt specific enough. I have a link that passes a value (field that is passed is called lastname) to a JSP where I want to show record info for that value that is passed.
    My question is how do I show the database record info on Show.jsp for the lastname field value of Jones where I want to use a Java Bean and Database helper class in Show.jsp
    Here is the message I get when I hit the link (LinkExample) and it goes to Show.jsp:
    org.apache.jasper.JasperException: Cannot find any information on property 'lastname' in a bean of type 'num.UserDB'
    .....My UserDB class:
    public class UserDB
    public User getUser(String lastname)
    User user = new User();     
            try          
         Class.forName("org.gjt.mm.mysql.Driver");
        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/dbconnone?user=smitherson&password=abcdefg");
        Statement stmt = conn.createStatement();
        ResultSet results = stmt.executeQuery("SELECT * from user where lastname = '" + lastname + "'");
         if(results.next() == true)
         results.next();
         user.setLastname(results.getString("lastname"));
         user.setFirstname(results.getString("firstname"));
                         user.city(results.getString("city"));
         catch(Exception e)          
             System.out.println("Exception..." + e);          
       return user;
    }Bean class:
    package num;
    public class User
      private String firstname;
      private String lastname;
      private String city;
      public User()
         //no arg constructor
      public User(String firstname, String lastname, Sting city)
          this.firstname = firstname;
           this.lastname = lastname;
    this.city = city;
      public String getFirstname()
              return firstname;
      public void setFirstname(String firstname)
         this.firstname = firstname;
      public String getLastname()
              return lastname;
      public void setLastname(String lastname)
         this.lastname = lastname;
      public String getCity()
              return city;

    Ok, jsp pages to not contain java beans, java beans are separate classes which you access from a jsp.
    Is this what you have done, i.e. created classes under classes/yourPackage ?
    If so, you do not need to recompile the class when you move it, you can move the pre-compiled class file.
    In terms of your error, I have no idea, but it looks interesting!!
    The most likely cause is a difference in the JDK versions you are running on the different machines. If the JDK on windows 2000 is older, you may need to upgrade it.

  • Reading Forms Key Mappings from java bean - how ?

    I want to be able to invoke key trigger code in a Forms 10g run-time from a java bean (extends BeanWrapper) either by:
    a) using inherited method calls passing the KeyEvent retrieved from my listener, or
    b) dispatching a custom event from the bean with a parameter value which identifies the key trigger to process (not the key code & modifier string).
    On a), I've not been able to identify any method in the BeanWrapper hierarchy tree that might help me do this, and samples like (http://forms.pjc.bean.over-blog.com/categorie-465294.html) seem to imply that no such method exists.
    In terms of b), the oracle.forms.engine.KeyMapTable class seems to be what I want (seems to translate the KeyEvent into a FormAction/string using server settings), but getting a hold of this object through (oracle.forms.engine.Main)getHandler().getApplet() doesn't seem possible.
    How are others invoking eg: key-crerec from a Forms 10g bean component in a way which is sensitive to server key mappings ?
    Thanks in advance for your help.

    I have no experience with KeyEvents in Forms, but if the KeyMapTable class really is the solution, can't you just instantiate one yourself.
    Looking at the constructor it only needs a single argument, the oracle.forms.engine.Runform class. You should be able to get a handle on it with:
    IHandler hander = getHandler();
    if (handler instanceof UICommon) {
        UICommon u = (UICommon)handler;
        // u.getDispatcher() should get oracle.forms.engine.Runform
    }Not sure if it will work, but you can give it a try.
    I love pushing the PJC and Oracle Forms applet to its limits. Not really sure if Oracle intended the PJC framework to do stuff like this, but it sure would have helped if they have JavaDoc about the oracle.forms.* classes
