Jsp:useBean no type with name

On a jsp page, why is it displying:
no type with this name could be found around
<jsp:useBean..?
Could any body help me out?

Hi Tom
There is a known limitation with Workshop where you would see those errors when the java classes (the types that error out) are part of you webproject itself.
The classes get compiled and get moved into web-inf\classes folder and somehow IDE does not get to see this in its classpath.
The workaround is to move those classes into a java project which will get compiled into a jar file that will be part of libraries (goes into APP-INF\lib).
You should not see those errors after the workaround.
This is a known limitation addressed via CR277571

JSP:useBean in Tomcat with external libraries

Hi!
I would like to use netbeans 4.1 for developing jsp-pages, but are facing a problem when trying to use the built-in jsp compiler.
in my code I use something like:
<jsp:useBean id="id" class="package.Classname" scope="application" />while package is an external package initially created from JAXB. To include it into netbeans, I have put the directory containing all the classes into the build libraries and also into the test libraries. In the 'Projects'-Explorer it shows all the classes contained.
When I try to run the jsp-File, I get an error like this:
Compiling 1 source file to C:\Develop\ApplicationDescriptionGenerator\build\generated\classes
C:\Develop\ApplicationDescriptionGenerator\build\generated\src\org\apache\jsp\general_jsp.java:48: cannot find symbol
symbol: class Classname
location packageI do not understand this behaviour, especially, as the 'web' folder created by netbeans includes all necessary classes, and when I copy it to my tomcat installation, it works fine.
Does anybody know, what I have to change, so that I can test it from inside netbeans?
Thanks a lot!

Here is the java program or bean class that I'm using, UserData.java compiled into UserData.class:
public class UserData {
String username;
String email;
int age;
public void setUsername( String value )
username = value;
public void setEmail( String value )
email = value;
public void setAge( int value )
age = value;
public String getUsername() { return username; }
public String getEmail() { return email; }
public int getAge() { return age; }
To put the data into the session, I used the following form:
<HTML>
<BODY>
<FORM METHOD=POST ACTION="SaveName.jsp">
What's your name? <INPUT TYPE=TEXT NAME=username SIZE=20><BR>
What's your e-mail address? <INPUT TYPE=TEXT NAME=email SIZE=20><BR>
What's your age? <INPUT TYPE=TEXT NAME=age SIZE=4>
<P><INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
and SaveName.jsp is this:
<jsp:useBean id="user" class="UserData" scope="session"/>
<jsp:setProperty name="user" property="*"/>
<HTML>
<BODY>
Continue
</BODY>
</HTML>

Jsp:useBean cannot locate class name

I used the following code in my JSP page:
<jsp:useBean id="myBean" class="myBean"/>
<%= myBean.getNum() %>
Container error:
Unable to compile class for JSP.

Thank you all for the timely responses...
I tried 2 classes actually. One in an unnamed package which resided in /WEB-INF/classes/ and other in /WEB-INF/classes/packageClasses/. Both qualified names were not detected by the container. I'm confused as to whether the container follows a specific search algorithm when using the jsp:useBean which is not specified in the specification?

Jsp 2.0 tagfile with name-from-attribute causes jasper exception

hello there, i'm messing around with jsp 2.0 tag files and can't get this simple example to work (tried it for hours in variations ...)
the tag file:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ attribute name="v" required="true" %>
<%@ variable name-from-attribute="v" variable-class="java.lang.Long" alias="a" scope="AT_END" %>
<c:set var="a" value="${123}"/>
<p> TAG: ${v} = ${a} </p>the jsp file:
<%@ taglib prefix="demo" tagdir="/WEB-INF/tags/demo" %>
<demo:varAttr v="x"/>
<p> JSP: x = ${x} </p>exception :
org.apache.jasper.JasperException: Unable to compile class for JSP
root cause:
java.lang.RuntimeException: org.apache.jasper.JasperException: /WEB-INF/tags/demo/varAttr.tag(3,1) The attribute directive (declared in line 2 and whose name attribute is "v", the value of this name-from-attribute attribute) must be of type java.lang.String, is "required" and not a "rtexprvalue".
... and so on
everything else works fine (name-given attribute).
i use tomcat 5.9.
any ideas? maybe somebody could try my example on a different installation.
thank you in advance for any help, because i ran out of ideas.

The attribute "v" is not allowed to take runtime expressions if you are using it with a name-from-attribute.
rtexprvalue defaults to true, so you must explicitly make it false.
<%@ attribute name="v" required="true" rtexprvalue="false" %>Cheers,

Type="Class" in the jsp:useBean tag

Hi every one
I create a class named quiz containing four Strings question,answer1,answer2,answer3
I initialize them in the constructor.
I made four get methods ...getQuestion(), getAnswer1 ...and so on.
I made the class implement the serializable interface.
in the main i created an object of that class and stored it on a file with .ser extension and i do the following in the jsp page
<jsp:useBean id="anyID" BeanName="name of the .ser file" type="className--i put the class name--"/>
but he gives me classnotfoundexception for the classname in the type field.
what can i do?
thnx in advance.

what can i do?Make sure that the class "quiz" is available to your web app.
Should be under the web-inf/classes directory (in its package directory)
Regarding your Quiz class:
- It must be in a package
- Also that it has a public noargs constructor:
package myPackage
public Quiz(){
}This class file should be in web-inf/classes/myPackage/Quiz.class
Hope this helps,

Changing button label;JSP; input type="submit" name="jboEvent" value="Search"

Hello everybody,
I try to develop a multilanguage application in which the button labels will change accordingly with the browser's regional settings.
The line in the generated DataQueryComponent.jsp file is the following:
<input type="submit" name="jboEvent" value="Search">
If I want to change the value like value="Rechercher" the application will not execute the query.
In fact the section
<jbo:ViewCriteriaIterate datasource="dsQuery" >
</jbo:ViewCriteriaIterate>
is not executed.
I tried to generate the button with:
<input type="submit" name="jboEvent" value="Rechercher" onClick="this.value='Search'"> ,
but for a long query the name Search will remain as button label on the screen.
Any new solutions, please?
Thanks in advance.

Jsp:useBean : Missing value of String classed bean with 'session' scope

Hi!
I'd like to ask some help.
I have these two JSP pages:
1.jsp<jsp:useBean id="str" class="java.lang.String" scope="session"/>
<html>
<body>
<% str="hello"; %>
<a href="2.jsp">click</a>
</body>
</html>
2.jsp<jsp:useBean id="str" class="java.lang.String" scope="session"/>
<html>
<body>
<%=str%>
</body>
</html>When I open 1.jsp in my browser, then click on the link, the result is "nothing" (empty string). Why does the bean lose its value on the way?
I use a Tomcat 5.5.9 server.
Any help will be highly appreciated.

You have to think of several scopes when working with JSP. The first is the local scope: the method _jspService() where all the work of the JSP is done. This acts as a normal method and is where all the sciptlet code goes.
When you use jsp:useBean you are creating two references to a new String object. One in the local scope accessible through <%= str %> and the other in the session scope.
When you do <% str = "hello"; %> you are changing the local str variable to reference the String "hello" (this is equivalant to doing <% str = new String("hello"); %>). Only the local reference is changed, not the second reference in session.
If you want the change to take affect, then you will have to store the new value in session with the same name:
<% session.setAttribute("str", str); %>

Need help with the jsp:useBean tag

Dear Fellow Java/JSP developers:
I am trying to use the <jsp:useBean> tag in a jsp that displays the values from a javaBean that gets populated by another class.
<%@ page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import = "java.util.ArrayList"%>
<%@ page import = "java.util.Iterator"%>
<%@ page import = "salattimes.CalendarParse" %>
<%@ page import = "salattimes.Salat" %>
<!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="test" scope="session" class="calendar.Time" />
        <% CalendarParse sTime = new CalendarParse();
            Time mytime = sTime.runExample();%>
        <%=mytime.getA() %>
        <%=mytime.getB() %>
        <%=mytime.getC() %>
        <%=mytime.getD() %>
        <%=mytime.getE() %>
    </body>
</html>However, up to now, I am only able to display the values on my JSP page using the scriptlet
<% CalendarParse sTime = new CalendarParse();
            Time mytime = sTime.runExample();%> to declare and create the object (the method call sTime.runExample(); populates the fields in the Java Bean), and the expressions:
<%=mytime.getA() %>
         <%=mytime.getB() %>
         <%=mytime.getC() %>
         <%=mytime.getD() %>
         <%=mytime.getE() %>to present the values on the screen. What I would like to do is assign the object that I create to a javaBean reference declared in a <jsp:useBean> tag as follows:
<jsp:useBean id="test" scope="session" class="calendar.Time" />
        <% CalendarParse sTime = new CalendarParse();
            test = sTime.runExample();%>and then present the values stored in the bean to the JSP page as follows:
<jsp:getProperty name="test" property="a" />
        <jsp:getProperty name="test" property="b" />
        <jsp:getProperty name="test" property="c" />
        <jsp:getProperty name="test" property="d" />
        <jsp:getProperty name="test" property="e" />
        <jsp:getProperty name="test" property="f" />Is this possible? When I try the above, I get "null" as my output on the screen. When I try the first approach listed above, I get the values I am looking for. Is there a way to accomplish this using the <jsp:useBean> approach?
Thanks to all those who reply.
Sincerely;
Fayyaz

The code:
<jsp:useBean id="calendar" class="calendar.CalendarParse" scope="session"/>
<c:set var="time" value="${calendar.time}"/>Would be roughly equivalant to:
calendar.CalendarParse calendar = new calendar.CalendarParse();
Object time = calendar.getTime();I assumed that the CalendarParse object was in the calendar package because that was were your Time class was (when you used <jsp:useBean id="test" scope="session" class="calendar.Time" />"), but when I look back at your original post I see I was wrong and the use of calendar as both the incorrect package and the variable name was confusing. To make the code more similar to your original post the code should have read:
<jsp:useBean id="sTime" class="salattimes.CalendarParse"/>
<c:set var="myTime" value="${sTime.time}" scope="session"/>
${myTime.a}
${myTime.b}
${myTime.c}
etc...Here is an explanation of the parts:
         /* name of the variable */ /* fully qualified class name, package.className */
<jsp:useBean id="sTime"           class="salattimes.CalendarParse"/>
/* name of the new object from bean */ /* source of object, variable.property */    /* Scope of new object */
<c:set var="myTime"              value="${sTime.time}"             scope="session"/>
/* data to display variable.property */
${myTime.a}Where a 'property' in a bean is defined as a method in the form of getProperty(). So the 'time' property is getTime() and the 'a' property is getA().

Type '[component name]' in CSS selector '[component name]' must be qualified with a namespace

I've recently upgraded my SDK to allow me encorporate other features such as the Text Layout Framework and such. To avoid issues i've had to make Flash player 10 as required, which is where the problems are occuring in my main project.
We knew the switch would cause some issues, and we now have a lovely batch of 100+ Warnings, that are all along the lines of
Type '[component name]' in CSS selector '[component name]' must be qualified with a namespace
all the warnings are on line locations that have no reference to the component they are talking about.. so i'm kinda stumped on what to do. Anybody else run into this issue before?

Jsp:useBean gives cannot be resolved to a type in Tomcat

Hi, I am using Tomcat 5.5
I have a simple JavaBean for test purposes :
import java.io.Serializable;
    public class testBean implements Serializable {
        int number;
        public testBean() {
        public int getNumber() {
            return number;
        public void setNumber(int newValue) {
            number = newValue;
    }In a file called testBean.java
I have successfuly compiled it and put the class file the WEB-INF/classes directory.
I have the following JSP page :
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<jsp:useBean id="pub" scope="session" class="testBean" />
<jsp:setProperty name="pub" property="number" value="1" />
<html>
<head>
</head>
<body>
<jsp:getProperty name="pub" property="number" />
</body>
</html>When I open this jsp page I get the following error:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 2 in the jsp file: /test.jsp
Generated servlet error:
testBean cannot be resolved to a typeThis example is pretty minimal and I don't understand why it doesn't work. The error seems to be coming from the first JSP statement.
Any help would be greatly appreciated.
Thanks in advance.

1. Put your bean class in a package.
package test;
import...........2. Put the .class file in web-inf/classes/test/testBean.class
3. Specify the fully qualified name of the class in the useBean declaration.
<jsp:useBean class="test.testBean" .../>Note: You'd be better off following the java bean naming conventions. Specifically your class name should be TestBean (first letter caps).

Unable to create the type with the name 'MSORA'. (Microsoft.SqlServer.ManagedDTS)

I am attempting to use the Integration Services Import Project Wizard within Microsoft Visual Studio and am getting this error
Unable to create the type with the name 'MSORA'. (Microsoft.SqlServer.ManagedDTS)
upon Import.
Can anyone shed some light for me on this cryptique error message?
Thanks for your review and am hopeful for a reply.

If you have the SSIS and SSDT (BIDS) installed then
I believe the DTS assemblies got derigistered, a typical outcome of corrupted software, so a full re-install would be the best option. VS +SQL Server + more
Otherwise, as a quick fix try to
reference the SSIS assemblies, like Microsoft.SQLServer.ManagedDTS.dll + more.
They are by default in C:\Program Files\Microsoft SQL Server\<number>\SDK\Assemblies.

Unable to create the type with the name 'ODATA'

On a test server with VS 2012 and SQL 2012 installed, I have created an SSIS project in project deployment mode. In the packages of the project I use the Odata source for SSIS. The packages run fine in VS 2012. But when I deploy the package to the Integration
Services catalog on the same server as where I am running VS 2012 I get a deployment error:
‘Failed to deploy project. For more information, query the operation_messages view for the operation identifier '25084'. (Microsoft SQL Server, Error: 27203)'
When I read this message from the SSISDB database, I see the problem with ODATA.
use SSISDB
go
select * from catalog.operation_messages where operation_id = 25084
--Failed to deploy the project. Fix the problems and try again later.:Unable to create the type with the name 'ODATA'.
As I said: the packages with the Odata run without error when tested from within VS2012 on the SAME server. When I deploy the project from Visual Studio I get the error.
For completeness: I have also tried deployment from VS2012 to another server where the SSIS Odata source has bene deployed. Also to no avail.
Jan D'Hondt - SQL server BI development

The next possiblity for me was to convert the project to Package deployment and see what the result I get. I have converted my project with package connections from project deployment to Package deployment. Then I deployed the package on the server in MSDB
catalog from SSIS. I.e. I connect with SSMS to Integration Services as an administrator and under the MSDB folder I added a new folder for my package. I then imported the dtsx into the mdsb package store. The Import worked. Still from within SSMS and connected
to the Integration Services, i right-clicked on the package in the MSDB store and selected 'Run package'. In the Execute Package dialog window, I clicked on 'Execute' and the package actually ran. The Odata connector was opened, it read the data and imported
into my database.
This experience made me realize what the real culprit was: The OData connector is a 32-bit connector in SQL Server 2012.
To prove this: with SSMS I connected to the SQL database server and in the Integration services catalog, i right-clicked on the package that was deployed in Project deployment mode, then selected 'Execute...'. In the execute dialog windo in the 'Advanced'
tab I checked 32-bit runtime. And the package ran.
To wrap it all up:
The Project deployment will work, but not with the Odata source as project connection. The Odata connection must be defined in each package as a package connection.
Run the deployed packages in 32-bit mode on the server

"no type with this name could be found at this location" error..

Though my project has been successfully compiled.
But when I open some specific class, it always comes out some error, says "ERROR: no type with this name could be found at this location". I am not quite clear, because the class underlined is absolutely in the project source folder. :(
Can anybody tell me what wrong with it?:(

The element type jsp:useBean must be terminated by the matching end-tag

Hi, I have deployed an application under WLS 8.1 SP4 and I get this error, when I try to access a page. I searched through the BEA site and it does refer to solution id S-13709 which says issue has been fixed in WLS 7.0. Hence should I not be seeing this error?
java.io.IOException: javax.servlet.jsp.JspException: The taglib validator rejected the page: "org.xml.sax.SAXParseException: The element type "jsp:useBean" must be terminated by the matching end-tag "</jsp:useBean>"., "

It would be useful if you provided a little more information about what you're trying to do on your JSP page. For instance, are you using an include directive or include action on the page? Are you trying to start the "jsp:useBean" element in one file, and end it in another? That, in particular, would likely be rejected.
