How to call an ejb method from jsp?

Hi, everyone!
Inside my JSP, I4m using scripts in order to show and receive information, that is, a form.But I don4t Know if I can use the same variables from the script in order to call the 'set' methods from my EJB.
Could anyone show me an example?
Thanks in advance,
Silvia

InitialContext ctx = new InitialContext();
     GeneralEditor editor = (GeneralEditor) ctx
                    .lookup("GeneralEditorBean/remote");
          GeneralService service = (GeneralService) ctx
                    .lookup("GeneralServiceBean/remote");
          LanMu lm = new LanMu();
          lm.setName("shdfkhsad");
          editor.add(lm);

How to call a EJB method from Session bean method

Please provide me an example code .

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

How to call a set method from within a constructor

Hello,
I want to be able to call a set method from within a Scanner, to be used as the argument to pass to the Scanner (from a source file). Here's what i tried:
private void openFiles()
        input = new Scanner( setSource );
    and here is the set method:
public String setSource( String in )
        source = in;
        return source;
    }obviously there will be more code in this method but i'm trying to tackle one problem at a time. Thanks in advance..

The "String in" declaration says: "Nobody may ever invoke setSource() without specifying a certain String. The content of the String is known at run-time only."
In no place in your code you say the compiler: "I want the 'in' variable (actually, parameter) of method setSource() to contain the first arg which is passed to the application".
This is exactly the same mechanism allowing you to write "new Scanner" with something inside the two parentheses.

How to call a static method from an event handler

Hi,
I'm trying to call a static method of class I designed. But I don't know how to do it. This method will be called from an event handler of a web dynpro for Abap application.
Can somebody help me?
Thx in advance.
Hamza.

To clearly specify the problem.
I have a big part code that I use many times in my applications. So I decided to put it in a static method to reuse the code. but my method calls functions module of HR module. but just after the declaration ( at the first line of the call function) it thows an exception. So I can't call my method.

How to call java class file from jsp

hi
we need to call java classes (which are written separately in .java file )from jsp file. we need it for our project if anyone knows about please reply us.
bye
siva sankari

you can call the methods in a lot of ways. you could use scriptlets with the
<%@ page import="package.class"%> and then inside instantiate an object
<%
MyClass mc = new MyClass(parameters if any);
mc.theMethodYouWantToCall();
%>or as Madathil has stated,
or use the JSP tags
<jsp:useBean id="anyname" class="classname"/>and then use the getProperty tag
or even Custom Tags

How to call custom Login Module from JSP

Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
Mike

You have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it!

You can make use of the constructor of the backing bean or the @PostConstruct annotation if you want to use managed properties.

It might compile perfectly well, but the message suggests that you didn't deploy it properly. The class loader can't find it.
That .class file should appear with its package directory structure under the WEB-INF/classes directory or in a JAR in your WEB-INF/lib directory in some WAR file. Does it?
