my beab local on cedars.FormBean, my Insert.java in WEB-INF/classes
thank you for the help

Hi,
don't think it will execute EL this way. However,you should be able to execute JavaScript (what you should keep in mind though is that any DOM manipulation on AMX page rendering is a risk and can put you into trouble). What is the HTML you want to insert (and to what extend do you control the metadata tags added to the AMX page this way? Wouldn't it be possible to add the content using AMX components?

  • ADF BC how to access session backing bean value in servlet

    Hi everyone,
    How do I access session backing bean value in a servlet?

    Frank, thanks for your reply.
    I'm not sure how I can incorporate this example into my situation. Let me explain more detail about my problem.
    "servlet" in my post here actually means a custom servlet I wrote for rendering an image that is stored in db as ordimage. In this servlet, I get hold of my appmodule by using Configuation.createRootApplicationModule(). By doing so (If I'm not wrong) a new database session/connection is created. What I'm going to achieve is set application context for this new session/connection in db with the data stored in a session backing bean in the view layer.
    I can pass the required data to the servlet thru url parameter, but I don't want to do it this way for the reason that the data may contains sensitive information.
    I hope I have explained myself well.

  • Using a bean in a servlet

    In my application I am having:-
    1)- a table in my database which contains the details of the user profile.
    2)- a bean which contains the string variables for all the user details along with the getters and setters.
    3)- a servelet and a jsp.
    In servlet I want to fetch entire data of the table and want to assign the values to the setters of the bean.
    in jsp I want to call that bean and want to use its getters to display the entire profile of the user.
    I am finding compleatly unable to use the bean in the servlet, please help me out.

    hi,
    try like this..
    after fetching all of your datas
    store in setter method of the bean.
    pass it as session.setAttribute ( "beanname", bean);
    in jsp
    get that session attribute
    beanname b = (beanname) session.getAttribute ( "beanname" ) ;

  • How do I update a bean value from an AJAX call?

    Hi all,
    How do I update a bean value from an AJAX call? I suppose I could write a servlet to do it. However, this seems like a common problem, so I was wondering if there was some built in solution.
    Thanks,

    Basically, I would user the following. The first choice for IE, the second for Firefox.
    new ActiveXObject("Microsoft.XMLHTTP");
    new XMLHttpRequest();
    GraeDon't do this to yourself. If it were that easy there wouldn't be AJAX frameworks for JSF. Find one you like and use it. I've used a4j (part of RichFaces) successfully.

  • Can't retrieve bean value from jsp!

    Here's the chain of events for my web app:
    JSP form (get info from user) -> forwarding jsp (uses bean to save info submitted to form)-> servlet (retrieves info from DB) -> JSP (presents DB info to user by populating values in text fields from original form)
    Right now, I can access all the values submitted to the first JSP from my servlet. However, after my servlet retrieves the info from a db and stores it in a bean and forwards the request (using requestdispatcher) to the 2nd JSP, I can't get the values from the bean from the 2nd jsp. I was able to use the bean to store the information submitted to the original JSP, however.
    Here's some relevant code:
    FROM FORWARDING JSP (which saves user-submitted info in bean)
    <jsp:useBean id="fxFormBean" class="fxmatcher.FxFormBean" scope="request"/>
    <jsp:setProperty name="fxFormBean" property="*" />
    <jsp:forward page="/FxMatcher" />
    FROM LAST JSP (which should populate form fields)
    header stuff:
    <jsp:useBean id="fxFormBean" class="fxmatcher.FxFormBean" scope="session"/>
    info retrieval:
    <INPUT TYPE="text" NAME="fx_key" value="<%= fxFormBean.getFx_key() %>">
    I wrote this JSP based on the example given here: http://www.jsptut.com/Editing.jsp, but I'm not getting the value from the bean. The result JSP just has value="".
    I'm pretty sure that my servlet is saving the info to bean correctly, but here's the code anyways:
    //retrieves info from DB
    FxFormBean fx = (FxFormBean) request.getAttribute("fxFormBean");
    fx.setFx_key (traderKey);
    fx.setAa_block(agent_block);
    fx.setAddition_to (additional_to);
    log("trader key: [" + fx.getFx_key() + "]"); //debugging code
    My debugging code did print out the correct info, so I don't think there's anything wrong with the bean or the servlet.
    I would appreciate any help. Thank you very much.

    The first JSP puts the bean in the request, the servlet retrieves the bean from the request and updates it but in the second JSP you set the scope to session:
    <jsp:useBean id="fxFormBean" class="fxmatcher.FxFormBean" scope="session"/>
    So the second JSP is looking in the wrong place for your bean. Change the scope in the second JSP to request:
    <jsp:useBean id="fxFormBean" class="fxmatcher.FxFormBean" scope="request"/>

  • Getting the values from   Servlet

    Hi EveryOne,
    I have done one thing using Flex,i have send the parmeters

    captured them and used them.Now what i want is i have to capture
    the values from servlet to flex .
    Response content in servlet is set to text/xml,any one please
    give me the idea how to do thsi or please send me some code to do
    this.
    {Sorry for my English} Thanks,
    Namala.

    Hi,
    You have to handle the result event of the HTTPService
    component. In the result handler you will have access to the
    ResultEvent object which will contain the response from the server
    in the "result" property. Please visit the URL below for more
    details on how to handle result from the server.

  • How to assign bean value to a local variable in JSP using struts.

    Hi everybody!
    I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
    we can have someting like this to display the value
    <bean:write name="detailService" property="status" />or
    <bean:define id="theStatus" name="detailService" property="status"/>
         This is country: <%=theStatus%>but an error occured when I tried like this:
    String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
    or
    String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
    Any help pretty much appreciated

    Java != JSP.
    The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
    The <bean:write> tag naturally just writes out what you tell it to.
    The <bean:define> tag defines a local variable, and gives it a value.
    this should do it.
    <bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
    <%
      String currentStatus = theStatus;
    %>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

  • How to call the form bean value on jsp withthe help of jstl tag

    hi
    all friends
    i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
    i now how to retrive the value through jsp:logic
    eg. <logic:empty name="userListForm" property="users">
    NO USER FOUND
    </logic:empty>
    see * userListForm mean formbaen name.
    * users means collection object.
    so how can i write above e.g in jstl

    You use the jstl core:if or core:choose combined with the EL:
    <c:if test="${empty users.userListForm}">
    NO USERS FOUND
    </c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

  • "Sharing" a stateful session bean between two servlets, beans

    Hello!
    I just started to learn some java ee programming and was wondering how i would share one stateful session bean between two servlets.
    I created the bean with @Stateful.
    I tried to inject the stateful bean in both servlets by @EJB and i can manipulate the object, but each servlet seems to have its own object.
    The bean has a remote interface that it implements.
    What i also tried was to add the mappedName to the @Stateful expression. Something like: @Stateful(mappedName="name") and to use the bean by @EJB(mappedName="name") but it had no effect.
    Im using glassfish 2.1 with netbeans 6.7.1 as my environment (standard settings)
    dummy question, but i googled like hours and couldnt find anything : \
    hope someone can help and sorry for my bad english
    greets and thanks

    Hi there!
    I think you are searching for something like an application wide singleton. There is the possibility to define such one in the Glassfish admin console.
    Hope this helps!

  • Using bean value in NLS text entry

    Hi all,
    Is there a way I can use the JHeadstart NLS function like
    title="#{nls['HOME_PAGE_TITLE']}"
    and include a bean value in the title
    eg " Welcome #{jhsUser.userId} to my wonderful application".
    I use JHS_TRANSLATIONS to store my text - if I enter the value as above, the jhsUser expression does not get rendered
    Cheers,
    Brent

    Just after posting this message I saw that the exact same thing had been done in the page I had just generated !
    So, the answer is to use this
    text="#{nls['HOME_WELCOME_MSG: #{jhsUser.displayName}']}"Is there a way to inject this in through the JHeadstart application definition ? If I place the value in the Display Title property it further wraps the text with extra nls and {}.
    Is my only option to create a custom template for grouTemplate.vm ?
    Cheers,
    Brent

  • Reset Managed Bean in Action Servlet?

    I've searched through the forum and have came close in finding the answer however the recommended solution is not working...
    How can I use this code:
    FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove("beanName");to reset a managed bean in an Action Servlet?
    How can I get the managed bean in the Action Servlet and reset it?
    I'm not after getting the HttpSession and invalidating it. I would just like to reset the managed bean in the servlet.
    Thanks!

    @RaymondDeCampo, Does resetting the managed
    bean same with resetting the session?If you remove the bean from the session, using traditional servlet APIs, it will appear to JSF as an uninitialized managed bean. When the application uses it next, JSF will instantiate it and set the properties as normal.
