Jsp:setProperty in WebLogic 6.0

Hi,
          We are using the WebLogic Web container with the Apache server and we
          have encountered a problem with the <jsp:setProperty> and
          <jsp:getProperty> tags. We are using WebLogic 6.0sp1.
          Reading the newsgroups, I noticed that this tag did not work in the
          previous versions of WebLogic and I was wondering if it has been fixed
          in 6.0sp1. Here's the snippet of JSP page that I use:
          <jsp:useBean id="beanName" scope="session"
          class="com.imoney.aplications.BeanClass">
          <jsp:setProperty name="beanName" property="userId" value='<%=
          request.getParameter("userId") %>' />
          </jsp:useBean>
          The problem is that the property userId of the bean with name beanName
          is not set by this tag. The JSP page compiles properly. The bean
          instance beanName is unique in the user session context.
          Thank you for any help,
          Brenda.

ValueBound() valueUnbound() for every jsp:setProperty .../

Hi.
          My helper class (implementing HttpSessionBindingListener) is put into
          the HttpServletSession.
          What I want is valueBound()/valueUnbound() on creation/deletion of the
          session.
          The following code:
          <jsp:useBean id="usession" scope="session"
          class="net.icteam.frame.session.UserSession"/>
          <jsp:setProperty name="usession" property="httpRequest"
          value="<%=request%>"/>
          <jsp:setProperty name="usession" property="httpResponse"
          value="<%=response%>"/>
          fires a valueBound()/valueUnbound() for every(!) <jsp:setProperty.../>
          My Question:
          Is this normal behaviour?
          Btw, the following code behaves normal(?):
          <jsp:useBean id="usession" scope="session"
          class="net.icteam.frame.session.UserSession"/>
          <%
          usession.setHttpRequest(request);
          usession.setHttpResponse(response);
          %>
          regards,
          Roman


Sounds like the correct behavior to me. Is there some specific thing that
          you are trying to do?

Custom JSP Tags for Weblogic

Hi,
          I have several questions regarding this topic:
          1) Does Weblogic 5.1 supports Custom Tags ? If so, are there any known
          problems ?
          2) Does Weblogic come with any tag libraries (for loops, if, etc) and where
          can I get them ?
          3) Are there any tag libraries out there (JRun, for example) that have been
          successfully run on Weblogic ?
          Any help would be much appreciated.
          Thanks,
          Jamie


As there seems to be general interest, a link would probably be a great
          help.

JSP 1.2 and jsp:setProperty

Has anyone got an idea why they decided to change the way the tag jsp:setProperty is handled?
In the JSP 1.1 specification, the condition to be checked before calling a single property set method was that the request contained the corresponding parameter, no matter what its value was, and the generated code would look something like this
String s1 = request.getParameter("example");
if (s1 != null) setExample(s1);
In the JSP 1.2 specification, it says the property is set only if the corresponding parameter' s value is not an empty string, as in
String s1 = request.getParameter("example");
if (s1 != null && s1.length() > 0) setExample(s1);
Which is what it would do with the setProperty with property="*", according to the JSP 1.1 specification.
This will cause me some trouble, because I will have to change my JSPs code in order to have bean variables set to empty string when the user doesn't input any value in the form (with beans having scope "session", of course).

I have not found any reasonable explaination for this.
The easiest fix that I could think of was on my JSP
pages before I submit I check to see if the value of
the field is "", if it is I set the value to
"emptyString". On the bean side I check the value of
the field property passed to see if it is
"emptyString" if it is I set it to "".
But this all seems an annoying nuisance when an empty
string is a perfectly valid value.I think I will fix it by having a reset method called in every JSP containing a form after the form itself has been "written" on the output stream with its fields' values. The thing is that I can't really find a good reason for this change they made: I can't believe there's a developer out there who would find this an improvement. The only thing I can think of is that they wanted to make the setProperty for a single property and the setProperty with property="*" have the same behaviour (the one I don't like).

Prob with jsp setProperty

Dear fouramites,
I am using jsp SetProperty standadr action tag to set from values to beans. In update when I am changing any form field value it is working fine but when I am deleting the form field value the previous value is being set to bean.
What is the solution to this problem?
Thanks & Regards
Kavyaanjali Jena

Dear Ram,
I am using the following code for both save and update functionality.
<html>
<%@ page session="true"%>
<%@ page language="java" %>
<%@ page import="models.*"%>
<%@ page import="beans.*"%>
<%@ page import="java.util.*"%>
<%
<jsp:useBean id="DATA_MODEL" scope="session" type="models.BeanInterface" />
<jsp:setProperty name="DATA_MODEL" property="*"/>
<jsp:forward page="/servlet/FrontController" />
</html>
When I change the value This code could set value to bean but when I totally delete the value it could not set null to bean but old value is retained.
I am using FrontController architecture.
Thanks & Regards

How to deal empty field with jsp:setProperty ...

Ive come across a bug in what I've done so far, not sure if its because of my approach...
I sucessfully store a value entered in a text field in a bean without any problems, and navigate back to the page where the value re-appears (via html, not relying on the browser). The problem is, if I edit that field to be blank, resubmit, then navigate back, the old value returns.
As far as I can tell, this is due to my jsp interpreting the input as null (ie. no input) and not changing the tag. IE sends the parameter as myPage.jsp?para1=&para2=some+value as it should (where para1 is the input in question).
I use the 'parameter="*"' usage of jsp:setProperty - is that a problem? Does this usage of setProperty not allow for setting values back to "" ? If so, how can i overcome this problem without losing the benefits of using <jsp:setProperty name="myBean" property="*">, that is, you can store all property values in javaBean in one go, instead of repeatly using <jsp:setProperty name="myBean" property="myProperty" value="myValue"> for each property.

hi,
first clearly tell u' r problem and then only any one can help u.
we are not unable to understand u'r query. it's like a Composition.

Can any one tell me how param is used in Jsp:setProperty ?

Hi Can anyone please explain me with example how param attribute is used in <jsp:setProperty>?
I have gone through the java doc but it still not clear to me....

Try the [JSP syntax reference|http://java.sun.com/products/jsp/syntax/2.0/syntaxref2025.html#8856]
It is very rare that you would use the param attribute, as most times you have your incoming parameter and bean property having the same name.
Example:
Say you navigate to http://localhost:8080/myApp/myPage.jsp?username=Bob
That sends a request parameter "username" with the value "Bob"
If we have a bean which also has a property username (getUsername(), setUsername()) (ie the property and the parameter have the same name) you can use the following jsp code:
<jsp:useBean id="user" class="com.mypackage.User"/>
<jsp:setProperty name="user" property="username">Translates approximately into
User user = new User();
user.setUsername(request.getParameter("username"));If instead the bean had a property "username" but the parameter was "userId"
<jsp:useBean id="user" class="com.mypackage.User"/>
<jsp:setProperty name="user" property="username" param="userId">
User user = new User();
user.setUsername(request.getParameter("userId"));Cheers,

Configuring JSP's in Weblogic server 7.0

Hi,
I'm trying to port my web application from weblogic server 6.1 to weblogic
7.0. I'm having a little problem with jsp pages in weblogic 7.0. Some of the text
box controls which are populated dynamically in my jsp pages are getting populated
with
"null" value in WL 7.0 e.g. in the following case
<%
String claim_id=null;
%>
<input type=text value=<%= claim_id %> >
on weblogic 6.1 an empty string is printed but in wl 7.0 null is printed as the
value for the text field.
I used the domain configuration wizard in wl 7.0 to make a WLS Domain and then
deployed my application. If I deploy the same application in one of the examples
domain which is installed with Weblogic 7.0 then everything works fine. So its
definity a configuration issue.
Could someone please help me with this.
Thanks,
-Taqdees.

As per the j2ee 1.2, jsp 1.2 specification mandates that the expressions
default must be "null".
We have introduced a new flag in weblogic.xml called printNulls which is
true by default meaning that "null" will be the default.
Setting this to false makes sure that expressions(<%=expr%> ) with "null"
results are printed as "" (earlier behavior)
Here is how to configure the printNulls from weblogic.xml :
<weblogic-web-app>
<jsp-param>
<param-name>printNulls</param-name>
<param-value>false</param-value>
</jsp-param>
</weblogic-web-app>

Question abt jsp:setProperty property="*" behavior

Hi,
I am trying to use the following tag
<jsp:setProperty name="formBean" property="*"/>
what this supposed to do is that if you have a bean which has same property names as your html form then instead of setting each property one by one this maps all the bean properties and assign the values.
However when I tried that it works as suggested but then I change a field name in my bean and recompile and run the jsp again, but it still works. I am not sure whether it is some kind of caching issue? I would think it shoould not set the form values as the bean field name doesn't match up with the form's property name. Please advice

I believe that the mechanism uses the bean's method names, not the field names, to determine what to call when you do property="*". so you can have the following
class MyBean{
String addr;
public void setAddress( String str ){
addr = str;
when you do this:
<jsp:setProperty name="bean" property="address"/>
it calls setAddress( String ).

It looks like a bug in JSP generator. If you look and the .java
          created by 6.1 it doesn't make any sence:
          String _propertyValue = request.getParameter("short");
          if (_propertyValue != null && !_propertyValue.equals(""))
          test.setShort(null);
          (needless to say that this works correctly in Resin).

Modify Collection with jsp:setproperty

Hello:
I have a problem with jsp and struts.
I have a collection of items (List) and view the elments in jsp page. This It works fine.
But the problem happens when i like modify the collection.
The code to view the collection in jsp is:
<jsp:useBean id="ItemListForm" class="com.myapp.struts.ItemListForm" scope="session" />
<html:form action="/ItemEditAction" >
<logic:iterate name="ItemListForm" property="listaItems" id="item" >
<P>
<BASEFONT SIZE="3">
<jsp:getProperty name="item" property="etiqueta" />
</BASEFONT>
<P>
<jsp:getProperty name="item" property="grafico"/>
<P>
</logic:iterate>
<P>
<html:submit>Save File</html:submit>
<html:hidden property="do" value="saveXML"/>
</html:form>
The question is:
How to modify the element "grafico" with jsp:setproperty.
Thanks for all.

Thank you, I had forgotten the set part, but then the next problem occurs:
<jsp:setProperty name="date" property="locale" value="${locales.locale}"/>
generates:
org.apache.jasper.JasperException: Unable to convert string '${locales.locale}' to class java.util.Locale for attribute locale: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
could I only use Strings as input?

Need Help: Problem with JSP setProperty to Bean

Hi,
This is my first time posting to this forum so I am not completely aware how Duke dollars work but if anybody can help me I will be happy to give some... whats normal for solving a problem?? 10??
Anyway... the problem...
I have a simple JSP with a simple HTML <form> that has a text field and a Submit button. Submit takes the user to the next JSP page however the setter method for property 'user' is never called. I can verify this through an attached debugger.
I am using Tomcat 5.5, and I never had a problem like this in previous versions of Tomcat.
I have tried changing the scope of the bean to request however nothing changed. I excluded all my business logic and tested this one more time just to make sure I wasn't inadvertadely screwing with something however this still does not work.
I am sure I am missing something small but for the life of me I can't figure out what.
Here is my code:
index.jsp
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <jsp:useBean id="something" scope="session" class="com.db.servlet.UserBean">
            <jsp:setProperty name="something" property="*"/>
        </jsp:useBean>
        <p>Select</p>
        <form id="Form1" method="post" action="multi.jsp">
            <p>User: </p>
            <input type="text" name="user" size="20"><br>
            <input type="submit" value="Submit">
        </form>
    <br><p>Or select Single mode.</P><br>
    <a href="tris.html">tris</a>
    </body>
</html>UserBean:
package com.db.servlet;
public class UserBean {
    private String user = null;
    public UserBean() {
    public void setUser(String user) {
        this.user = user;
    public String getUser() {
        return user;
}

Oops!
I not only realized my mistake, I also accidentally posted this in the wrong forum. I meant to post in the JSP Forum.
For reference, what I did wrong was I placed my setProperty tag in index.jsp rather than placing it in multi.jsp (the file specified in the form action).
Everything works now.
