How to display current user using HTML portlet

Hello,
Is it possible to show any text such as Greeting, Current User (ex, Hello, Kevin) using HTML portlet. Can I use <oracle></oracle> tags to get the current user from the API?
Please suggest me.
Thanks,
Satish

Thanks for your suggestion. There is also another way for this:
In a Portal text field (CMS item) you can type
#USER# to display the username of the authentificated user or
#USER.FULLNAME# to display the full name.
Thanks,
Satish

How to display current date in query header?

Hi,
How to display current date in query header?
I use Query Designer for development.
Thanks,
Arun KK

Hi Arun,
You can define fixed header lines and footer lines so that when you generate the query list, they can receive current values of certain fields. When you define a header line or a footer line, you must specify a character string of the type &field, where field is the short name of a field.
This function allows you (for example) to place a sort criterion in the header line.
You can include the following fields as variables in the headers directly:
%NAME
Name of the user processing the query
%DATE
Current date
%TIME
Current time
%PAGE
Current page number (6 characters)
%P
Current page number (3 characters)
These fields can be used in the short forms N,D,T and P. If you want to use these letters as short names for query fields, the field values from the query are used.

1. Current work flow :-In web site the user have to register themselves in the web site and enters his details along with user id, password and email id. Once user
is registered then he will login with his user id and password. The user id is picked from login control and that set in “SPWeb.CurrentUser” as user id and system uses "Membership.ValidateUser" method to Authenticate user for login.
2. New Requirement: we would like to facilitate the user to login with Email id as well as user id.
Problem:
We replaced "Membership.ValidateUser" method to our own method to Authenticate user with email id/user id and password.
When user is login with user id and password it is working successfully but in the case of email id and password –“the email id is picked from user control and set as
"HttpContext.Current.User.Identity.Name" but we are not getting “SPWeb.CurrentUser” and it shows null value.”
We are able to get user id from database using email id of user. Please help us how we can set user id in "SPContext.Current.Web.CurrentUser".

How to display current navigation on "Body only" page layout

I create a new page and applied "Body only" page layout which is basically PageFromDocLayout.aspx
But it doesn't show current navigation. How do I show current navigation on left side of the page? I have the code which will display current navigation but I don't know where to paste it inside page layout because there doesn't seem to be any space for that.
Or is it something that I can enable disable from somewhere?

There is no QuickLaunch snippet. There is one by the name of "Vertical Navigation" which I think is QuickLaunch snippet so I copied its code in PlaceHolderMain section inside page layout but getting error:
ContentPlaceHolder can only be used in .master files.
EDIT
Ok I managed to do it by adding Vertical Navigation inside a separate <td> in my master page and then I only display it when page is not home page. So the is something like:
HTML CODE IN MASTER PAGE
<td id = "leftmenu" style="display:none">Vertical Navigation code here</td>
<td>ContentPlaceHolderMain here</td>
JAVASCRIPT CODE
if(page is not home page then)
document.getElementById("leftmenu").style.display = "block";

I'm not sure why you would do it the way you have it implemented in 3 select lists.
Why not use a Item Type of Date Picker, and let the user use the pop-up Date Picker to select the date.
You code has some fatal flaws:
1) You can't see any data before 2000
2) You can't see any data past 2010 (probably not an issue now)
3) It's possible to specify February 31 as a date
Using the built-in Date Item type will eliminate these issues and at the same time, make your UI more streamlined.

Displaying current user's first and last name on a report.

I would like to dispay the current user's name on a report. I've tried using User() and NQ_SESSION current user .
These two options display the User ID (i.e. User name is Jon Smith. there ID is COMP/JSMITH.
Using the two methods above the ID (COMP/JSMITH) is displayed. Is there a way I could display Jon Smith?
I thought their might be a way to use Full Name or First and Last Name.

How to display dynamic images using Struts

I am storing the image name in bean. I want to use the <html:img> tag to display my images. How can i do that using struts.
Something or sort..
<html:img src=bean:write name="pageEntry" property="pageImg"/>
Thank You

* In your web.xml file, add the struts-html-el.tld definition from the struts\contrib\struts-el\lib directory
* Add this tag library to your JSP page; something like:
<%@ taglib uri="WEB-INF/struts-html-el.tld" prefix="html-el" %>* Refer to the following example:
<html-el:img src="${pageEntry.pagePic}" />* This assumes that pageEntry is a Bean, and pagePic is a bean variable accessed by the getPagePic() method.
