Value comparison on jsp page

Hi
I want to compare value stored in bean object with another value to show suitable message on page
Eg
if(#{bean.userstatus=="N"}){
//show this
}else{
//show this
Can anybody please tell me how to do comparison as examplified above
Thanks

Use the 'rendered' attribute. It accepts a boolean expression. If it evaluates to false, then the component simply won't be rendered in the component root, otherwise so.
Here are some basic examples:<h:someComponent rendered="#{myBean.booleanValue}" />
<h:someComponent rendered="#{myBean.intValue > 10}" />
<h:someComponent rendered="#{myBean.objectValue == null}" />
<h:someComponent rendered="#{myBean.stringValue != 'someValue'}" />
<h:someComponent rendered="#{!empty myBean.collectionValue}" />
<h:someComponent rendered="#{!myBean.booleanValue && myBean.intValue != 0}" />
<h:someComponent rendered="#{myBean.stringValue == 'oneValue' || myBean.stringValue == 'anotherValue'}" />In your specific case, just do:<h:someComponent rendered="#{bean.userstatus == 'N'}" />
<h:someComponent rendered="#{bean.userstatus != 'N'}" />

How can I share values between different jsp pages?

Hi,
I'm doing a jsp, bc4j application (JDeveloper 9.0.3), and I need to share some values between different jsp pages. To do this,
I have used the tag <jsp:usebean.....></jsp:usebean> in this way:
on pageone.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
on pagetwo.jsp
<jsp:useBean id="param" scope="session" class="MyPackage.Parameters" ></jsp:useBean>
and so on, in order to refer to the same instance of the class "Parameters".
After deploying, the application works well only if the client is the same pc where the AS resides, otherwise the variables of "Parameters" are null.
Please, could you help me?
Thanks
Nunzio.

I am seeing an indication on 9.0.3 that static includes are not static, but instead always dynamic. The compiler generates a call to the included page, and doesn't include the content in the calling page as it should.

Get Javascript Value in a JSP page

Let's say this is my javascript function in a html page
.<head>

function getFields(){
if (row >= 0){
for(var i=0; i<costForm.elements.length; i++){
if(costForm.elements.type == "text" || costForm.elements[i].type == "hidden"){
dynTableFields[i] = (costForm.elements[i].value)? costForm.elements[i].value : "";
if(costForm.elements[i].type == "select-one"){
dynTableFields[i] = costForm.elements[i].selectedIndex;
</head>
How do i get the costForm.elements.length value in another jsp page. Coz the html page has dynamic rows by the users. and i need the values in the jsp page to know how many rows the user created.
using normal request.getParameter("costForm.elements.length") doesn't work

request.getParameter() will only get data that's been submitted thru a form or the query string of a URL. You'd have to record the length in a hidden field to read it on the back end, and then you can't just loop thru the fields like that in JSP on the server anyway, unless you have all fields named with a prefix and number, like: field1, field2, field3, etc.

Passing values to the JSP page - Urgent

Hi all,
I have to pass the user id value to the JSP page. I have written the following code in the doInitialization() method
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
IAuthentication ia = UMFactory.getAuthenticator();
IUser portalUser = ia.getLoggedInUser(request.getServletRequest(), request.getServletResponse(false) );
s = portalUser.getUniqueName();
IPortalComponentSession componentSession = ((IPortalComponentRequest)getRequest()).getComponentSession();
Object o = componentSession.getValue("myEvents");
myEvents = (LoadEvents)o;
//myEvents = (LoadEvents) myContext.getValue("myEvents");
myEvents.setUserId(s);
myContext.putValue("myBeanName", myEvents);
I have also defined myEvents as a bean in my JSP page with scope APPLICATION. But I get User Id as "NULL".
Thanks in advance.

HOW to send a value to another jsp page

HOW to send a value to another jsp page, like user name in one jsp page to another jsp page

In the most simplest form...
// pageA.jsp
<html>
<body>
<form action="pageB.jsp" method="post">
<b>First Name:</b> <input type="text" name="FNAME" value="Joe">
<input type="submit" value="Submit">
</form>
</body>
</html>
// pageB.jsp
<html>
<body>
<b>Name:<b> <%=request.getParameter("FNAME")%>
</body>
</html>

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:
<html>
<body>
<h2 align="center"><u><b><span style="background-color: #FFFFFF"><font color="#C0C0C0" face="Comic Sans MS">Leave

this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

package_weight = letterTF.getPackageWeight();
System.out.println("Package: "+package);//it will print Package: null
System.out.println("Weight: "+weight);//it will print Weight: null
System.out.println("Description "+description) //it will print Description: null
As I observed its not making the set methods from LetterForm.java
I am dealing with this bug for a couple of days an i didn't managed to break it. If anyone has an idea would he be so kind to share it with me.
Thanks in advanced,

Basically your form beans are the place holders or containers for your jsp attributes. It has to be mapped in such a way that when the form is submitted the user entered values get populated on to your form bean.
For Eg:
JSP
<html:form action="accountSearchResults.do">
<html:text property="myName" size="15"/>
//USE ONLY STRUTS TAGS IN JSP's. U CAN REFER TO
//http://struts.apache.org/1.x/struts-taglib/tlddoc/index.html
//THE PROPERTY NAME "myName" SHOULD BE DEFINED IN
//YOUR FORMBEAN WITH getMyName AND setMyName
//METHODS DEFINED
</html:form>
struts-config.xml
<form-beans>
     <form-bean name="addEditAccount" type="org.apache.struts.validator.LazyValidatorForm">
          <form-property name="myName" type="java.lang.String">
          </form-property>
     </form-bean>
</form-beans>
<action-mappings>
     <action path="/accountSearchResults" type="com.zzz.AccountSearchResultAction" name="addEditAccount" scope="request">
          <forward name="success" path="NextPage.jsp">
          </forward>
     </action>
</action-mappings>
Action Class
Since we have defined the form bean as a lazyvalidator instance you can use:
PropertyUtils.copyProperties(targetBean, form);to fetch the values entered by the user. Try to use struts tags in your jsp's and map the properties to your form bean variables. Hope that helps.

Values from a jsp page are null in an Action class

hi, i am working on an application...i have a jsp page with several inputs (type=text) and when a submit the form to to my action class all values received are null.
Here is a part of code:
the jsp file: letter.jsp
<form target="_self" action="/Test/editLetter.do" name="letterTF">
<table>
<tbody>

How to get the value in one JSP page to another?

Hi,
I have problems in passing the value around in JSP. I have two JSP pages as below:
test1.jsp
I try to get the vaule from my textbox by using:
String strUser = request.getParameter ("strUserName");
Then i print out by using: out.print(strUser); then i can get the value and put on my page (For example, i get ABC on my page).
test2.jsp
Next, i want to get the value from strUser (which mean that the one i already display on page in test1.jsp, ABC) to insert into my table by using INSERT INTO statement. Then i try by using
String strUser1 = request.getParameter ("strUser");
Is it possbile for me to do that? I cannot get anything to insert into my table. Then i tried out.print(strUser1); then i found that i get NULL value.
Could you please give me some guidance?
Thanks you very much for any advise you may give me.

How can I pass a variable value from first jsp page to thired jsp page

In my program ,threr are three jsp pages . I want the first pages's variable value in to thired page .How can I acess.
I used the request.getparameter() ,but when I print the value , null value is getting .

request parameters only last for one request.
To save them longer than that you need to save them somewhere.
Couple of alternatives
1 - store them to session
session.setAttribute("username", request.getParameter("username");
2 - create a hidden field on page 2 and store the value from page 1 there. When you submit page2, you can get it on page3 with request.getParameter again.
<input type="hidden" name="username" value="<%= request.getParameter("username") %>">

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-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>
</application-config>

      </component-profile>
    </component>
</components>

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.

hi there,
In the MCV there is a part about struts, this is a descent way to do this.
how to do it:
create an actionform containing all the properties of the page.
then when you submit your form use an method in the actionforms (that you have written) that makes sets your data in a xml file.
this works very quickely and i use it in production...
you can choose if you want the xml to generaded hard coded or via a parser.
greetings

Values on the jsp page not loading after refresh

Hi All,
I have a problem in getting the values back onto the jsp page after a refresh. After the first refresh i get null values.
Let me know what i should use: is it 1. request 2. application or 3. session scope? I have to keep my application running for ever (as long as the server is running) refreshing every 3 minutes. So i used application scope but in vain.
Also i am using requestDispatcher and forwarding the req,res. I came to know that this method has some problems if we use request attributes. Do i need to use a send.Redirect instead?
Let me know the correct procedure.
Thanks in advance.

Thanks in advance.r u forwarding request to same page. ?
try using sendRedirect with URL rewriting:
for eg .
response.sendRedirect("/myPage.jsp?id="+idValue+"");
and access id on page submit.
as
request.getParameter("id");
This should work .
