How to use Custom Tags for Theme and Base Map Definitions

In Mapviewer documentation I've found the following new feature:
The XML definition of a theme or base map now supports application-specific
attribute tags. You can use the Custom Tags option in the theme definition in Map
Builder to specify tags and their values, which can be interpreted by your application
but are ignored by MapViewer itself.
I'm able to define a custom tag in Mapbuilder, but how can I use it in my Application?
Thanks.

As he said, you have to use as Platform service to create adapter in OIM.
tcUserOperationsIntf service = Platform.getService(Thor.API.Operations.tcUserOperationsIntf.class);
HashMap<String,String> searchmap=new HashMap<String,String>();
searchmap.put("Users.User ID", userID);
tcResultSet searchset=service.findAllUsers(searchmap);

Urgent-how to access custom tag from jsp tag

I have a problem accessing a custom tag from a jsp expression.
Details: I have a custom tag that returns a string variable. I need to access that variable from jsp expression <%%>.
Can any body help me?

Tags don't "return" values as in the normal sense.
They can only support TEI (Tag Extra Information) that just stuffs a declared variable into the page's state.
For example, if the tag class had a public method called getValue(), you could do the following:
<xmp:mytag id="foo"/>
<%
out.println("value is " + foo.getValue());
%>

How to use messagebar tag in jsp page

i am working with "messagebar" control presents in the htmlb controls.
my aim is to display the message after pressing some button. how to give link for that.
if anybody have smple code for it please send me with component,jsp page and bean(if used)......
ragards,
ajoy

Hi,
If I understood you right, then you want to update the message shown in your messgebar, when user clicks on button.
To achieve this, have a MessageBar with no message text. And when ever a button is clicked in the event handling method of your button set message text to your messagebar.
public void showMessage(String message, MessageType type) {
messageBar.setMessage(type, message);
public void onClick(Event event) throws PageException {
showMessage("Clicked Button", MessageType.INFO);

How to use nested tag in Struts

Hi..
Can any one guide me how to use nested tag in Struts. So far i already tried bean tag with no error but when i try to use nested tag i got error like
javax.servlet.ServletException: Cannot find bean: "" in any scope
Below are my class:
action class
session.setAttribute ("MyDetailList", detailList);
JSP page
<logic:iterate id="list" name="MyDetailList">
Company ID : <bean:write name="list" property="companyID" />
</logic:iterate>
For bean tag, i got no error at all and below are my code for nested tag
action class
session.setAttribute ("MyDetailList", detailList);
JSP Page
<nested:nest property="MyDetailList">
Make : <nested:text property="make"/>
Car ID : <nested:text property="carID"/>
</nested:nest>
When i run the code, i got error message
javax.servlet.ServletException: Cannot find bean: "" in any scope
Any body can help me?

what am I doing wrong?You will notice above that I mentioned
YOU CAN'T USE CUSTOM TAGS AS ATTRIBUTES TO OTHER CUSTOM TAGS
(was that loud enough for you to notice this time)?
Try
<html:text styleId="instruction" styleClass="text" size="50" name="instruction" property="value"/>
//or
<html:text styleId="instruction" styleClass="text" size="50" property="instruction" value="<%= instruction.getValue() %>"/>
better alternative: populate your formbean with your action and just have:
<html:text styleId="instruction" styleClass="text" size="50" property="instruction"/>
If you set the "instruction" property of your formBean in the action, the value will be automagically reflected here.

Custom Tags in JSP

I am new to using custom tags. Is there a nice book or site which I could read on custom tags.
Also, I kind of understand custom tags but not completely confident.
I have a JSP that uses two custom tags, flight and segment. Basically, goes through each segment with flight tag and prints out attribute of segment with Segment tag. The code looks like this.
<flifo:flight isParent="true" fromParent="true" >
 <td bgcolor="<%=bgcolor%>" width="94" valign="top" class="t7">
 <%-- Print FLIGHT NUMBER --%>
 Flight
 <flifo:segment fromParent="true" attribute="flight_num" />
 
</flifo:flight>
In the above code I just have flight_num but there are other attributes that it prints out. I want to check an attribute in segment and if it is ture then display some of the tags. How can I do it?

This has helped me a lot in the past:
http://java.sun.com/developer/Books/javaserverpages/cservletsjsp/chapter14.pdf
... and the book it's extracted from is very good too.

Can i use Custom Tags for Database retrieval (as per MVC pattern)?

In our project we are dealing with database, and i've used the Cutom Tags for database retrieval (as per the Article from Mr Faisal Khan) and it is working fine. But i have a doubt if it affects the performance in any way . I wanted to know if its recommendable to use Custom Tags for the DB retrieval as per MVC Pattern or shall i create a intermediate bean and then call the bean in custom tag.
Thanks
Prakash

Putting database code in your JSPs certainly couples your view to the database. That's usually not good.
If it's a simple app, it might be justified.
When you start having lots of pages and complex business logic it becomes less attractive. - MOD

Can i make own formatted textbox using custom tag

Hai,
Can i create own format textbox similar to vb activex control.for example i want make own formatted textbox for enter only numeric value if entry any alpha value it's show error.Is this possible using custom tag

Hai,
Can i create own format textbox similar to vb
activex control.for example i want make own
formatted textbox for enter only numeric value if
entry any alpha value it's show error.Is this
possible using custom tag
If you mean a custom text box in a web page without an applet (in other words an html component), then Java has nothing to do with it. And by mentioning activex (even only in a 'like' comparison), and custom tag, you are once again hinting that you want an html component. I think you need to place your request to a JavaScript Forum, which, once again, has absolutely nothing to do with Java.
A "custom tag" in JSP is not an HTML Tag. It may look a little like an html or xml tag, but it is evaluated on the server side. The control you need must be executed on the client side, which, once again, tells me you need to post to a JavaScript forum.

How to use bean:write inside jsp:include ?

I got a problem about JSP's syntax. The following is my code:
<%@ include file="<bean:write name="HelloForm" property="target" />"%>
The double quotes inside bean:write is my problem. Could you please teach me how to use bean:write within JSP's include? Thank you!

http://java.sun.com/products/jsp/syntax/1.2/syntaxref12.html
Include Directive vs <jsp:include>
The include directive <%@include %> is done at page translation/compile time.
It effectively pastes in a static file, and then compiles the JSP as if it was all one file.
As such, you cannot provide a runtime expression to it.
To do runtime inclusion, you need to use the <jsp:include> tag which does except runtime parameters.
<%String test = request.getParameter("pageInfo");%>
<%String link = test + ".jsp"; %>
<jsp:include page="<%= link %>" %>Unfortunately you can't use the tag with a bean:write tag as well, you can only use runtime expressions, not tag. So you have to do the include with
<jsp:include page="<%= HelloForm.getTarget() %>" />

hi rachna,
JSP has a default(implicit) session object...... use the getSession(true) method on the session object and then going u can either get or set attributes depending on the requirement
That was in general and now with the issue u have got..... what u can do is that the u can create session for every user who logs in and when he/she tries to login again then u can probably check for the existing session object in the JSP and perform the logic as required..... any clarifications plzzzzzzz let me know
Thanks n Regards
