GetProperty in JSP

Hey there im new to the whole jsp thing. I got my server up and running and less sophisticated files run on the tomcat. So theres no problem.
The time is now <%= new java.util.Date() %>
worked so it should be fine.
Now i want to call System.getProperties which should give me info about my system but what ever i tried. Nothing seems to work. Could you please help me?
Example:
Your os is: <%= System.getProperty (os.name); %> or something

Hi,
This is a simple program which gets all the system properties and prints it one by one.
<HTML>
<BODY>
<%
java.util.Enumeration e = System.getProperties().propertyNames();
while( e.hasMoreElements() )
String prop = (String)e.nextElement();
out.print(prop);
out.print(" = ");
out.print( System.getProperty(prop) );
out.print("<br>");
%>
</BODY>
</HTML>
Hope this helps you.
Thanks

Regarding jsp:getProperty

hi
i have a bean. I am setting the values of the bean and setting that bean as an attribute in the session.
In another jsp i am able to access the bean using
<jsp:getProperty name=".." property="..">
Here the name is the same as the attribute name.
But here i am not using <jsp:useBean /> tag.
I have read some where that <jsp:getProperty> or <jsp:setProperty> should be used with the <jsp:useBean> tag.
Please correct me where i am wrong?

I too read the same.
But i done an example on my local machine and i am able to access the <jsp:getProperty> without <jsp:useBean>
Consider Testbean.jsp

Why do you use jsp:useBean?

Hi,
I have one "simple" question :) : When or why do you are using <jsp:useBean>,<jsp:getProperty> and <jsp:setProperty>?
For practice, I am creating a form, sends the data to a servlet and the servlet "packs" the parameter into a Bean and put this Bean into a request- or SessionScope. After that, my resultpage could access the property name of the bean with (for instance) sessionScope.Bean.name.
I wanted to use the 3 tags above first, but after I realised the way I describes above I didn't have to use these three jsp tags. Therefore I wonder when you are using these tags.
Thnx
Alex

hi
The component model for JSP technology is based on JavaBeans component architecture. JavaBeans components are nothing but Java objects which follow a well-defined design/naming pattern: the bean encapsulates its properties by declaring them private and provides public accessor (getter/setter) methods for reading and modifying their values.
Before you can access a bean within a JSP page, it is necessary to identify the bean and obtain a reference to it. The <jsp:useBean> tag tries to obtain a reference to an existing instance using the specified id and scope, as the bean may have been previously created and placed into the session or application scope from within a different JSP page. The bean is newly instantiated using the Java class name specified through the class attribute only if a reference was not obtained from the specified scope. Consider the tag:

How to get the ServletContext when writing a class

Morning,
I've got a project using al least 4 jsp documents that try to manipulate a mysql database
To access the database and get a connection, i've put this syntax at the start of each document
<%! Connection con; %>
<%
String url = (String)application.getInitParameter("databaseUrl");
               String username = application.getInitParameter("username");
               String password = application.getInitParameter("password");
               Class.forName("com.mysql.jdbc.Driver").newInstance();
           con = DriverManager.getConnection(url, username, password);
               %>Those documents also use classes that I create, what I want to do is keep the code I've written above in one place instead of 4 different places, Is there a way I can use the application variable, which belongs to ServletContext in a class (not a servlet)

This syntax reference JSP 2.0 : http://java.sun.com/products/jsp/syntax/2.0/syntaxref20.html
covers JSP actions such as jsp:useBean , jsp:getProperty and jsp:setProperty.
The API for JSTL is pretty intuitive:
http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/index.html
But if you need more details on a particular JSTL tag you can refer to the JSTL 1.1 Specification - it's a PDF document.
JSTL also uses EL (Expression Language) which is also covered by the JSTL specification and by the above JSP 2.0 syntax reference.
There are many JSTL tutorials and articles too, but most of them are old so they contain JSTL 1.0 code.
To get yourself started you need jstl.jar and standard.jar which come with the latest JSTL 1.1 distribution found here:
http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html
Standard-1.1 (JSTL 1.1) requires a JSP container that supports the Java Servlet 2.4 and JavaServer Pages 2.0 specifications. Jakarta Tomcat 5 supports the new specifications. The Standard-1.1 taglib has been tested with Tomcat 5.0.3.
After you have set up your environment you can test it with a small sample of JSTL code like this:
inside sample.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="someVariable" value="Hello World!"/>
<c:out value="${someVariable}/>
null

Re: Running Struts on weblogic - more info

          The responses below are from Craig McClanahan who is one of the guys in involved

          that!

          The "bean-cookie.jsp" actually uses <jsp:getProperty>, not <jsp:setProperty>.
          In this particular case the relevant spec language is Section 2.13.3:
          "An <jsp:getProperty> action places the value of a Bean instance
          property, converted to a String, into the implicit out object, from
          which you can display the value as output. The Bean instance
          must be defined as indicated in the name attribute before this point
          in the page (usually via a useBean action).
          Note the word "usually" -- the reason it is here is because custom tags can be
          defining elements as well, as long as they use the corresponding TagExtraInfo
          class and, in the tag, call pageContext.setAttribute() appropriately. In this
          page, the call
          <bean:cookie id="sess" name="JSESSIONID"/>
          is the defining element that looks up the cookie named "JSESSIONID" (more on
          that
          name below) and exposes it as a JSP bean. This tag precedes the use of the bean
          in statements like this:
          <jsp:getProperty name="sess" property="domain"/>
          which looks up the "domain" property of the cookie (i.e. it calls getDomain())
          and
          writes that to the output stream.
          Thus, this page conforms to the JSP 1.1 spec requirements.

          Note the phrase "or some other element" -- again, custom beans can be defining
          elements, so this page would be valid even if it had been using
          <jsp:setProperty>
          instead. It is interesting to note that the corresponding paragraph in the JSP
          1.2 draft specification (Section 4.2.2.1, p. 63) has been clarified to indicate
          this:
          "The name of a Bean instance defined by a <jsp:useBean>
          or some other element. The Bean instance must contain the
          property you want to set. The defining element must appear
          before the <jsp:setProperty> element in the same file.
          so the confusing parenthetical comment about <jsp:useBean> has been removed.
          Even
          if it's a little inconsistent in 1.1, the intent is clear -- custom tags can be
          defining elements for JSP-accessible beans. That is the whole point of the
          TagExtraInfo functionality.

          Servlet API Specification, Version 2.2, Section 7.1.2, p. 35:
          "Session tracking through HTTP cookies is the most used
          session tracking mechanism and is required to be supported
          by all servlet containers. The container sends a cookie to the
          client. The client will then return the cookie on each subsequent
          request to the server unambiguously associating the request
          with a session. The name of the session tracking cookie must
          be JSESSIONID.
          Prior to 2.2, the servlet container could use whatever cookie name it wanted.
          However, for 2.2 onwards, the cookie name is fixed for all containers.
          There may well be spec compliance issues with Struts that need to be fixed (such
          as the current question over whether body content can be accessed in the
          doEndTag() method of a custom tag). However, on these two issues, Struts

          Sam, it interesting that OTHER application servers can support struts. It's
          probably just a case that you don't handle the specification very well. Is this
          also why your server has not passed the J2EE compatibility tests? Oh, I'm sure
          that you guys will complain about SUN and licensing. I understand your
          complaints and I agree, but that doesn't have to do with specification
          compliance! ;^)
          BTW, everyone, there is a serious ClassCastException that should be fixed in
          service pack 6. This particular exception illustrates that BEA Weblogic 5.1 sp5
          does not support web applications properly. I created an web application under
          Tomcat3.1 and moved it to Weblogic5.1sp5. I was receiving ClassCastExceptions
          when I was trying to access an object that was passed in my JSP request and
          display it on a JSP page. I'm grateful that one of the support people finally
          fixed the problem. However, this was only a temporary patch. I'm told the
          "official patch" will be included with sp6.
          Let's hope that some day BEA Weblogic will be compliant. BTW, why is it you are
          charging so much. Oh it must be for the great support! ;-)
          If you BEA Weblogic users would like some addition links to application servers
          that support JSP1.1/Servlet2.2 specification better than Weblogic, here are two.
          http://www.orionserver.com (This is actually a full J2EE class application
          server. It has not passed the compatibility test, but they do a hell of a
          better job than BEA Weblogic. BTW, it's much cheaper too.)
          http://www.caucho.com/ (This is an open source effort. They are only in beta
          with EJB support and they are using Servlets and XML to implement the EJB
          specification. There is a charge for commercial use. Many people are using
          this engine to do the JSP/Servlets and Weblogic to do EJBs. Wonder what will
          happen when they provide EJB support?)
          You know I thought this news group was to help solve problems with Weblogic. It
          has turned into a newsgroup that tries to hide problems and respond with
          dis-information. However, this is just my opinion, just as Sam expressed his
          opinion about struts. That's assuming Sam's email was an opinion, I just
          figured it was since he did not know the JSP1.1/Servlet2.2 specification. Sorry
          if I was wrong.

Populating combobox in jsp page from javabean using jsp:getProperty tag

hi,
i am new to jsp, so i don;t know how to populate a combobox in jsp page with productid attribute from a javabean called Bid . i want to have a code to automatically populating combobox using the attribute value from javabean.
please reply me.
<jsp:useBean id="bidpageid" class="RFPSOFTWARE.Bid" scope="session" />
<jsp:setProperty name="bidpageid" property="*"/>
<table width="50%" align="center" border="0">
   <tr>
    <td width="30%" align="left"><h4><b><label>Date (dd/mm/yyyy) </label></b></h4> </td>
    <td><input type="text" name="date" size="11" maxlength="10" readonly="readonly" value="<jsp:getProperty name="bidpageid" property="date"/>" > </td>

      <option value="<jsp:getProperty name=bidpageid" />Sachin</option>
      <option value="Hello">Vishal</option>
    </select></td>
</tr> and the javabean for Bid is as follow :
import java.util.Date;
import RFPSOFTWARE.Product;
public class Bid{
private Product product;
private Integer bid_id;
private String description;
private Date date= new Date();
public Integer getBid_id() {
return bid_id;
public Date getDate() {
return date;
public String getDescription() {
return description;
public Product getProduct() {
return product;
public void setBid_id(Integer bid_id) {
this.bid_id = bid_id;
public void setDate(Date date) {
this.date = date;
public void setDescription(String description) {
this.description = description;
public void setProduct(Product product) {
this.product = product;
}

No Sir,
I think I did not explained clearly.what I try to say is I dont want to use JSTL.I am using only Scriptlets only.I can able to receive the values from the database to the resultset.But I could not populate it in Combobox.
My code is :
<tr>
<td width="22%"><font color="#000000"><strong>Assign To Engineer</strong></font></td>
<td width="78%">
     <select NAME="Name" size="1">
<option><%=Username%></option>
</select> </td>
</tr>
in HTML
and in Scriptlets:
ps1 = con.prepareStatement
          ("SELECT Username FROM Users");
          rs2=ps1.executeQuery();
          System.out.println("SECOND Succesfully Executed");
          while(rs2.next())
               System.out.println("Coming inside rs2.next loop to process");
               Username=rs2.getString("Username");
               System.out.println("Success");
               System.out.println("The value retrieved from UsersTable Username is:"+Username);
In the server(Jboss console) I can able to display the username but I could not populate it in the Combobox .
Can you now suggest some changes in my code,Please..
Thanks a lot

jsp:getProperty.... in a taglib-tag ???

Hi !
I have taglib where I have defined a lots of classes and one of them I have a attribute who should be dynamic. I have tryed this:
<easyTagz:submit iteration='<jsp:getProperty name='submission' property='maxCount'/>' />
but it dosen`t seem to work....
Any suggestion :-)

Dosen`t seem to work, have tryed and gets this error message:

Jsp:getProperty in tag attributes

Hii....
I have a custom tag that displays some information based on an attribute of the tag. I want to set information from a bean to the attribute using the jsp:getProperty tag...
I want to do something like.......
<mytagprefix:MyTag attribute1='<jsp:getProperty id="myID" property="name"/>' />
If I do it right now I am getting the string <jsp:getProperty id="myID" property="name"/> inside the my TAG.
any help will be appreciated.
sanjay.

I'm a bit rusty on custom tags, so maybe this isn't the best solution, but until you find a better one you can try '<%= myID.getName() %>' as the attribute.

Struts, JSP 1.1 spec and WLS 5.1 - issue with useBean and getProperty

Hi there, I am attempting to compile a JSP page using Struts tag libraries and Weblogic 5.1 with Service Pack 9.I have defined the bean using <jsp:UseBean id="myBean" ... > and then attempt to access its methods using <jsp:getProperty name="myBean" ... > This fails with a 'myBean is not defined as bean' error. When I replace the <jsp:getProperty ...> with a scriptlet e.g. <%= myBean.getCustomerName()%> it compiles and runs just fine.I have read that the WLS server may be enforcing a strict implementation of JSP spec 1.1 which the Struts tags may not be adhering to (?).Oddly, when I start WLS without invoking the Service Pack, the error disappears and the <jsp:getProperty> works as expected!Any official reason for this strange behaviour? ... I'd like to avoid using scriptlets if possible.Thanks in advance,Rash

Hi.
The following link shows supported versions of apache:
http://edocs.bea.com/wls/platforms/index.html#apach
In short, WLS 5.1 does not support Apache 1.3.20. The latest supported version is
1.3.19.

Combining jsp getProperty with HTML EMBED

Hi, Just a quick question, I have a couple of JSP/HTML books and I can't find a way of achieving this;
basically I have a webpage that embeds a VRML file like so
<EMBED SRC="/VRML/stair.WRL"
TYPE="model/vrml"
WIDTH="300"
HEIGHT="300"
VRML_SPLASHSCREEN="TRUE"
VRML_DASHBOARD="TRUE"
VRML_BACKGROUND_COLOR="#0066CC"
CONTEXTMENU="TRUE"
>
This works fine, the problem is that I now have a servlet that dynamically generates the VRML file to be displayed, so I need a way of inserting this variable into the EMBED header, how do I do this?
If it can't be done with JSP etc then how about a JavaScript solution?
Anyway, ive tried a few things and Im out of ideas
Cheers
PS, the current JSP property finder;
<jsp:useBean id="vrmlFileFinder"
type="legato.VRMLBean"
scope="request" />
<jsp:getProperty name="vrmlFileFinder" property="fileName" />

There are two issues here
1 - generating the WRL file (from your servlet)
2 - generating the EMBED tag in the HTML/JSP page
These are two different requests to the web server.
1- generating the WRL file:
You say you have a servlet which generates the VRML code?
Does it generate it to file, or output it directly?
If it outputs it directly, just point the src of the tag to be your servlet
ie
<EMBED SRC= "/servlet/VRMLServlet"...
This will invoke your servlet, and return the code to the browser. (ie as long as the servlet sends it a WRL text format, it can't tell the difference)
2 - generating the EMBED tag:
If you want to dynamically choose which file to include, then JSP would do it like this:
<jsp:useBean id="vrmlFileFinder" type="legato.VRMLBean" scope="request" />
<EMBED SRC="<jsp:getProperty name="vrmlFileFinder" property="fileName" />"...
Remember that the JSP code gets executed first, so if the property evaluates to "/VRML/stair.WRL" all the browser will see is
<EMBED SRC="/VRML/stair.WRL" - it doesn't see the JSP code at all.
Hope this helps.
Cheers,

Jsp:getProperty

Hi!
I create a JSP page wich is going to process a bean put in the session by other jsp page.
The code is like this:
<jsp:useBean id="realty" scope="session" class="com.admin.bean.Realty" />
<jsp:setProperty name="realty" property="*" /> For the page where the user is going to enter the information and...
<jsp:useBean id="realty" scope="session" type="com.admin.bean.Realty" />
<jsp:getProperty name="realty" property="*"/> for the page where the data processing is going to occur.
The problem I have is that once I enter the informacion on the page1 and press submit. I got the following error:
Cannot find any information on property '*' in a bean of type 'com.admin.bean.Realty'
Can sombody help me with that??
Thanks

There is no property "*" applicable to a get[/i]Property.
With [i]setProperty, it makes sense, because you are telling the computer set ALL the properties of the bean which have corresponding parameters in the request.
However getProperty is designed to display/return one property. How could you display multiple properties? So * makes no sense in that case.

How come property attribute of jsp:getProperty knows which method to call

Hello friends,
I could not understand How come property attribute of <jsp:getProperty knows which method to call
<jsp:useBean id="test" class="BeanTest.testing" scope="page" />
<jsp:getProperty name="test" property="name" />
there is no method "name" in testing.class file
if u see the existing examples "date" given in TOMCAT , it is using many <jsp:getProperty tag, but the property name is not equal to the method method name in the Bean file
thanks,

First do you know what a
bean property sheet is?
If not say so.
Second, to your question
The Java Runtime Environment (JRE) uses introspection to identify the appropriate get() or set() methods of that bean. What is introspection?
Introspection is a process that allows the class to expose its accessable variables and methods and allows other classes to see what they can do with that class when requested. Eg:
public class MyBean{
private String someValue = null;
public MyBean(){
someValue = "Some String Value";
//Introspection will reveal this method
public String getSomeValue(){
return someValue;
} and
<jsp:getProperty name="...." property="someValue" />
will call the getSomeValue() method

Formatting fonts within jsp:getProperty tag????

I'd diplaying a piece of information on one of my pages using the jsp:getProperty tag.... there seems to be no way I can effect the display of the property with the font/color that I want - when I look at the resulting HTML code, I see that this tag has created a new HTML table specifying the class "inFieldSet" (a CSS class I presume, and which I also presume if overriding my desired font/color settings). Is there a way to make the page display the property using the font/color that I want without writing a custom tag?

All the JSP getProperty tag does, is get a string returning the value of a property. It would not apply any formatting to your page.
I would take a look at the "getter" for this property to see what value it is returning.
Most probably it is returning a chunk of preformatted html.

Using jsp:getProperty ... inside a scriptlet

When I use the following line in a jsp file,
<% boolean userExists=<jsp:getProperty name="xxx" property="exist/> %>
it gives an error saying that a term is missing, when I try to load this page. Any help is appreciated.
Thanks,
Nalini

Don't put the bean in the servlet context but use the HttpSession
session.setAttribute("xxx", loginBean);
in the JSP retrieve the bean by
<jsp:useBean id="xxx"
scope="session"
class="package.LoginBean" />
Where id = the name of the attribute in the session
class = the full package name of the bean.
Or
LoginBean myBean = (LoginBean) session.getAttribute("xxx");
Don't forget the import
<%@ page import="package.LoginBean" %>
