Fixing the lenght of content to be displayed on JSP page

hi,
i want a CSS property which can display specific no. of character of string. My means that I want to display the email of currently logged in user, the place that is available to display email is only 30 character, if length of email is greater than 30 charater then discard the remaining character and display it, otherwise display the actual content of email.
thanks in advance

H:inputTextarea problem to fix the lenght of character

hi,
I have one h:inputTextarea on my page.i want to fix the lenght of the character. i want to put the character lenght 20 character,so user can not put the 21 character in textArea.

You can probably use validators.
I stole following snippet from [IBM |http://www.ibm.com/developerworks/library/j-jsf3/]
<h:inputText id="firstName"
                value="#{UserRegistration.user.firstName}">
     <f:validateLength minimum="2"
                               maximum="25" />
</h:inputText>With some alteration you should be on your way (I think)

HI Tan ,
I pressume that you wanted to make use of PDK, the code can go like this .

How To Customize displaying of JSP page From Backing Bean

I would like to customize the displaying of jsp page from backing bean based on user Roles
For example
- if the Role is Admin then backing bean should display Admin.jsp
- if the Role is Guest then backing bean should display Guest.jsp
Any pointers/suggestions will be highly appreciated
Regards
Bansi

Thanks to all for providing thoughts
I wanna make it more Dynamic. In the sense
"Backing Beans should drive the rendering of first jsp page in the application " and not jsp page driving the backing bean or not to put some kind of hard coding in jsp page to see if its admin user then display certain set of UI Components or certain set of other UI components for other users.
As we have atleast 10 different Roles and there can be Composite Roles i.e. combination of two roles. In this case how does the Backing Bean drives the rendering of jsp page?

Bansi

To search a record from the table by providing a search button in JSP page

Hi,
My problem statement is:
I have a jsp page which displays a table containing records. I have to provide a button called search and a condition in a textfield so that the record which matches the condition gets highlighted.
Can anyone solve my problem statement. Its urgent.
Suraj.

Example:
on the jsp page, read the matched value the server provides and use it to put the statement in bold using the <b> tag (I dont know the syntax for highlighting).
<%String matchedString=(String) request.getAttribute("matchingString");%>
Then in your list:
<%if(matchedString.compareTo(thisRecordString)==0){%>
<b>
<%}%>
//your text goes here
<%if(matchedString.compareTo(thisRecordString)==0){%>
</b>
<%}%>

Bean Value display in JSP Page

Hi,
I am trying to display a value stored in my bean on the jsp page. The value is to be displayed on the initial jsp page.
   public void doInitialization()
          request = (IPortalComponentRequest) this.getRequest();
          response = (IPortalComponentResponse) this.getResponse();
          myContext = request.getComponentContext();
          myProfile = myContext.getProfile();
          Statement += "doInitialization";
          BeanContainer = new MockUpBean();
          BeanContainer.setValues( Statement);
          myProfile.putValue( "myBean", BeanContainer);
          // reset String
          BeanContainer = ( MockUpBean) myProfile.getValue( "myBean");
    }// public void doInitialization()
On the JSP Page side:
<jsp:useBean id="myBean" scope="application" class="MockUpBeanPackage.MockUpBean" />
<%= myBean.getValues()%>
The jsp page does no pick up the value I try to store in the doInitialise method.
Any thoughts on what I may have done wrong in my code.
I try response.write("Test"), this too does not show up in my JSP page.
Any advice would be appreciated.
Thank you
NAC

Marty,
The portalapp.xml file is as follows:
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>
</application-config>
<components>
    <component name="MockUpPage">
      <component-config>
        <property name="ClassName" value="MockUpPackage.MockUpPage"/>
        <property name="SecurityZone" value="MockUpPackage/low_safety"/>
        <property name="ComponentType" value="jspnative"/>
        <property name="JSP" value="pagelet/InitialPage.jsp"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
</components>
<services/>
</application>
Again any help would be apreciated. I have used this piece of code to write values to beans in various projects, never had any issues. This is the first time I am having an issue with this piece of code.

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

Read a property file value and display in jsp page

I need a solution for the below mentioned scenario,
I want to read a value from the property file in JSP page.
For Example, Let us have a property file called A.properties, in the file, we have a value, username = Sam.
I want to bring this value in the jsp page.
Please assist in this issue.
thanks in advance.

If you are using struts, then you have to first load the taglib like
<%@ taglib uri="/WEB-INF/strutsresources/struts-bean.tld" prefix="bean" %>and then access the particular property like
<bean:message key="welcome"/>Also, you have to define <message-resources> in struts-config. Though I am not into struts for year now, So, please confirm the code.
