Accessing bean attributes in a JSP

Hi,
I am sending a bean from a Servlet to a JSP as follows:
request.setAttribute("newclientTEST", ro_client);
this.getServletContext().getRequestDispatcher("/jsp/private/research/UserAdded.jsp").forward(request,
response);I can then access the bean in UserAdded.jsp page as follows:
<jsp:getProperty name="newclientTEST" property="username" />This works fine and returns the username from the bean but I am a little confused why this is working. From what i have read about JSPs so far in order to access properties of a bean in a JSP we first of all have to make a reference to the bean as follows:
<jsp:useBean id="newclientTEST" scope="request" class="ie.scourced.beans.PrivateClientBean" />Why does it work for me when I don't refer to the bean using useBean??
Thanks

how?.... mmmm ... did ... (head scratch) ...I miss that.
Thanks a million for spotting that, I really did appreciate that.

Accessing session attribute in output jsp page

Hi i am not getting any output in jsp page...
i am getting just heading
i think some problem with Session attribute..
if so how to access session been in jsp page
my code is here
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%--
The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library... action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

how can i access that session attribute in jsp

Assining a bean attribute to a jsp variable

I am writing a struts application and am using
<bean:write name="configattribute" property="name"/>
to print out info on my jsp page.
I was wondering if I could assign that value to a local jsp variable so I can check its value and change the colour of the text accordingly.
e.g.
String name = <bean:write name="configattribute" property="name"/>;
if name.equals("Ben"){
out.print(<font color=\"red\">;
else{
out.print(<font color=\"blue\">;
}

You should still be able to use the code I listed...the logic:iterate tag creates the bean "configname" in the page scope. So you should be able to do something like this:
<logic:iterate id="configname" name="confignames">
   <tr>
      <td>
<% ConfigName configname = (ConfigName)pageContext.getAttribute( "configname" );
   String color = "blue";
   if( "julius".equalsIgnoreCase( configName.getOwner( ) ) )
      color = "red";
   } %>
        <span style="color: <%= color %>"><bean:write name="configname" property="owner"/></span>
      </td>
      <td>
         <bean:write name="configname" property="name"/>
      </td>
   </tr>
</logic:iterate>Does that sound right?

Using Bean Attributes in a JSP for a h:commandLink

Hi,
I am very new to JSF so apologies if the answer is obvious.
I currently have a ArrayList of products obtained from a database.
Using...
<h:dataTable value="#{ProductBean.productList}" var="product">
                <h:column>
                    <f:facet name="header" >
                        <h:outputText value="Title"/>
                    </f:facet>
                    <h:outputText value="#{product.title}"/>
                    <f:facet name="header" >
                        <h:outputText value="Picture"/>
                    </f:facet>
                    <h:outputText value="#{product.picture_url}"/>
                </h:column>
            </h:dataTable>The contents of the ArrayList are printed out fine.
I am now looking to iterate over the items to output a link
so far I have... but it doesn't seem to work
<c:forEach items="${ProductBean.productList}">
                    <h:form>
                    <h:commandLink action=images/"#{productList.picture_url}" title="#{productList.title}"><h:graphicImage url="thumbs/#{productList.picture_url}" width="100" height="75" alt="" /></h:commandLink>
                </h:form>
                </div>
            </c:forEach>I think the problem lies with appending the "images/" before the url
Ideally I would like it to replicate the actual HTML view which is
<a href="images/london_flight.jpg" title="London in Flight"><img src="images/london_flight.jpg" width="100" height="75" alt="" /></a>If anyone could shed any light it would be much appreciated.
Thanks in advance

Thanks that was helpful so I have modified my code to...
            <c:forEach items="${ProductBean.productList}" var="product">
                <div class="thumbnail">
                    <h:form>
                    <h:commandLink action="images/#{product.picture_url}" title="#{product.title}"><h:graphicImage url="thumbs/#{product.picture_url}" width="100" height="75" alt="" /></h:commandLink>
                </h:form>
                </div>
            </c:forEach>But I seem to be getting a jsp error...
javax.el.ELException: Not a Valid Method Expression: images/#{product.picture_url}
How can I append "images/" to the action without it falling over.
Thanks

Referencing beans as bean attributes in struts tags

Do struts tags allow you access bean attributes when the bean itself is an attribute of another bean?
If so, what would be the syntax?
For instance, I have bean A that contains as an attribute another bean B. I want to test for the value of
an attribute within B. Let's say I have bean A where A has get/set methods for B and B has get/set methods for an attribute called 'amount'. Then can I say something like:
<logic:equal name="A" property="B.amount" value="1">
I tried this syntax and also "B.getAmount()", but neither seems to work.
I have also tried <logic:equal name="A.B" property="amount" value="1">
but this doesn't work either.

I've used that x.y syntax before in some tags, but I don't know if logic tags support it... you should be able to do this:
<bean:define id="B" name="A" property="B" />
<logic:equal name="B" property="amount" value="1">

Hi Dominik,
Having a closer look at the problem, we found it is not the number of users.
It seems our JAVA components keeps the conenctions with SAP open and reopens a new one every time we start the component.
If we finished solving the problem, I will publish the solution.

[JDev 10.1.2] Compare JSTL var attribute with sessionScoped bean attribute

I'm new to JSTL.
I'm looking for a way in JDev 10.1.2 to compare a sessionScope bean attribute (sessionScope.User.Username) and a JSTL attribute variable. For this purpose I've developed the following code:
+<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>+
+<%@ page import="bean.User"%>+
+<jsp:useBean id="User" class="bean.User" scope="session" />+
+...+
+<c:forEach var="Row" items="${bindings.ReadOnlyViewObject.rangeSet}">+
+<c:choose>+
+<c:when test="${Row.CreatedBy == sessionScope.User.Username}">+
+...+
+</c:when>+
+</c:choose>+
+</c:forEach>+
+...+
However it doesn't work on the test line. I'm not able to compare Row.CreatedBy to sessionScope.User.Username.
I've also tried <c:when test="${Row.CreatedBy == User.Username}"> without success.
Could you help me?
Thanks.

The bean property will have an initial lowercase name, so try sessionScope.User.username ?
I believe since you used the jsp:useBean, that you can also just use User.username without the "sessionScope" in there, as well.

flag = false;
document.forms[0].admissionRank[i].focus();
document.forms[0].admissionRank[i].select();
break;
if (flag == false)
break;
In this validation i want admissionRank to be removed from the original arraylist if following condition gets satisfied
"(document.forms[0].allApplicantID[j].value == document.forms[0].applicantID[i].value )"

Unable to call bean method at second JSP.

I have a Bean called "Database" in that two methods
1.public String methodReturnsString()
2.public List methodReturnsList()
And also i have three jsp's.
1.First.jsp
2.Success.jsp
3.fail.jsp
i called methodReturnsString of "Database" in the First.jsp ,after receiving intended String from the method methodReturnsString() i.e "success" or "fail" i can goto Success.jsp. or fail.jsp.
Assume i got String "success" eventually leads me to Success.jsp , In this Success.jsp i was trying to access Bean method methodReturnsList() , Now the problem is I cant access the Bean method methodReturnsList() in Success.jsp, where i want to print the List that is returned by methodReturnsList().
Can anybody tell me what is the mistake i am doing.
here is "Success.jsp"

Access dynamic attributes BPM; error while activating the process in sxi

hi everybody,
I have to access dynamic attributs in a BPM condition. I thought I could achive this when I click the radiobutton "contextobject" in the condition editor.
When using the value-help button on the contextobject a huge list of objects is shown for selection.
Strange to me is that also the radionbutton "interface-variable" is checked. I can not uncheck this radiobutton. But this makes the error while activating:
"Containerelement 'IDOC_'MyContainerelement'{XSDSIMPLE::xsd:string;SHeaderSUBJECT:ht' does not exist".
Has anybody expirience using the dynamic attributes/contextobjekts in BPM?
Thanks, Regards Mario

Hi all,
it seems to be impossible to access the attributes:

How can I access the Attribute Values from the Search Region

Hi all,
I have a table which contains Company id, department id, and PositonId. For a particular Company and Department there may be multiple records.
I have to pupulate a table which contains the position and other details that comes under a particular Department and Position based on the selection in the Three comboBoxes.
Also I have to populate a select many Shuttle to add new postions and records under a particular Department.
I created a query panel *(Search Region)* for the serch and a table to display the data. That is working fine.
Now the issue is I am using a view criteria to populate the shuttle with two bind variables ie, DepartmentId and CompanyId.
If the serach will return a resuktant set in the table it will also pupulate the correct records, otherwise ie, if the if the serch result is empty the corresponding iterator and the attribute is setting as null.
SO I want to access the attribute values from the Search Region itsef to populate the shuttle.
I don't know how can I access the data from the Search Region.
Please Help.
Regards,
Ranjith

you could access the parameters entered in search region by the user as follows:
You can get handle to the value entered by the user using queryListener method in af:query.
You can intercept the values entered as described
public void onQueryList(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
List<Criterion> searchList = qdes.getConjunctionCriterion().getCriterionList();
for ( Criterion c : searchList) {
if (c instanceof AttributeCriterion ) {
AttributeCriterion a = (AttributeCriterion) c;
a.getValues();
for ( Object o : a.getValues()){
System.out.println(o.toString());
//call default Query Event
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
public void onQueryTable(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
private void invokeQueryEventMethodExpression(String expression, QueryEvent queryEvent){
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
ExpressionFactory efactory = fctx.getApplication().getExpressionFactory();
MethodExpression me = efactory.createMethodExpression(elctx,expression, Object.class, new Class[]{QueryEvent.class});
me.invoke(elctx, new Object[]{queryEvent});
Thanks,

How to access an attribute(this is referencing to another class) in a class

Dear Gurus,
I have to read an attribute of a class and that attributes type another class.
I have intantiated the class and my question is how to read the attribute. I know I can not dirrectly read the attribute since this is another class. I think I have to first reference the attribute right? Please advise me.
My code looks like below:
data: lo_fpm                                 type ref to if_fpm.
data: lo_msg_mgr                        type ref to if_fpm_message_manager.
data: lo_component_manager    type ref to cl_fpm_component_manager.
lo_fpm = cl_fpm_factory=>get_instance( ).    " cl_fpm_factory is a class which has a static method get_instance
lo_msg_mgr = lo_fpm->mo_message_manager.
lo_component_manager = lo_fpm->mo_component_manager.
The above statement is giving syntax error. I do not know why.
The basic difference b/n the two methods is if_fpm~mo_message_manager    type ref to if_fpm_message_manager    and
mo_component_manager     type ref to cl_fpm_component_manager.
Any help would be appreciated.
Thanks,
GSM
