Custom Tag - how to use tag value= %=jsp% / ?

Hello friends,
I am new to custom tags. I have written simple tags that handle value="some hard-coded stuff">.
But cannot not implement jsp-supplied values? Could you please help with advice?
Basically, how to implement a custom tag that would allow:
<mylib:mytag value=<%=somejsp%> />
Thank you!

Just define it in your .tld ...
Example:
<attribute>
<name>comments</name>
<required>false</required>
//IF this is set to true, u can add your jsp stuff... in your value
<rtexprvalue>true</rtexprvalue>
<type>String</type>
</attibute>
Usually, the .tld goes in WEB-INF/lib ... some people just put it in WEB-INF/

How to use tag?

Hey,
I was working on some examples and I saw one example had used "tag" when creating a table.
I'm just wondering why and when do you use tag?
what is is for?

For an example of how to use tags with (iPhone) table views, take a look at the code in my reply to [How to edit label in custom UITableViewCell?|http://discussions.apple.com/thread.jspa?messageID=11498619&#1 1498619].
In that example two labels are added to each new cell when it's created in the tableView:cellForRowAtIndexPath: data source method. The OP wants to change the text in one of those labels when its cell is selected by the user, and the code to do that is in the tableView:didSelectRowAtIndexPath: delegate method.
But how does the delegate code get the address of either label, and how does it tell one label from the other? This problem is solved by using the 'tag' property of each label. Note that the code which creates the labels includes statements to set each of the tags. The left label tag is set to 1, and the right label tag is set to 2. The delegate method then sends the [viewWithTag:|http://developer.apple.com/iphone/library/documentation/UIKit/Ref erence/UIViewClass/UIView/UIView.html#//appleref/doc/uid/TP40006816-CH3-SW26] message to the selected cell. When the integer '1' is passed as the argument, the viewWithTag: method returns the address of the first subview it finds with a tag value of '1'.
Hope that helps!
\- Ray
p.s.: In previous threads my poor vision saw a lower case 'L' in your alias instead of the second 'i'. When I correct that mistake your alias looks more like a form of David. Sorry for the past mistakes. - R

How to use Copy-Value function?

Dear Friends,
I have query on how to use Standard function Copy-Value.
Please have a look @ the help.sap.com example use of Copy-Value function.
http://help.sap.com/saphelp_nw70/helpdata/en/26/d22366565be0449d7b3cc26b1bab10/content.htm
I have designed the same example. Please see the mapping I've defined for this example :
http://www.flickr.com/photo_zoom.gne?id=930440086&size=o
Please see the resuts, its working perfectly. See the top image :
http://www.flickr.com/photo_zoom.gne?id=930440300&size=o
Ok, now lets come to the issue. Please consider the same example , If I have more than one partner
and I want to use the address field to the customer street,city & zipcode using copy-value function, how will I achieve this?
Please see the resuts.See the bottom image :
http://www.flickr.com/photo_zoom.gne?id=930440300&size=o
I think you all got the issue, if not please reply back.
Looking for your answers!!!
Best regards,
raj.

The CopyValue function considers only values in the first context of the queue.
When the queue has more contexts, the other contexts are ignored.
In online help, the element addrDat is 3 times under name, that means 3 values are in the first context.
That means: For the first occurrence of the partner it is correct, for all other partners, the values of the first context is taken. The online help does not express this, so it is misleading and should be changed to an example where address is not beyond a node with occurrence inbounded.
In practical cases the copyValue can only be used for values that appear in source just one time, like the IDOC header fields, as it works like a constant.

Stefan

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is

I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.

Hi, I don't know if it may be the cuase of your problems, but you should narrow the Object obtained doing the lookup, like this:
FirstHome home = (FirstHome) PortableRemoteObject.narrow(ctx.lookup("FirstEJB"), FirstHome.class);

How to use threads in JSP???

hello
i want to use threads with JSP.
i want to write a jsp page which will
start 2 different threads. the 1st thread should just display a message and the second page should redirect this page to another jsp page.
till the redirection is goin on, the message should be displayed in the browser from the 1st thread.
i dont know actually how to use threads in JSP by implementing the Runnable insterface, if not m then how do i do it ??
thanx
Kamal Jai

Why do you want to use threads to do this ??
If you write a message and do a redirection, the message will be displayed until the other page will be loaded into the browser...
I already launched a thread from a JSP but it was for a four hour process where the user can close his browser windows.

How to use Special value set with Column clause to display addtional column

Dear Yaseen,
To get the value in formula cumulative,after you have created the formula for that particular key figure,go to edit and click on tab "calculations".
In that select overall result as 'count all values not equal to zero' and single result as 'count all values not equal to zero' .
And mark the cumulative check box underneath.
I hope you get the desired result and please do me favour .

Google is your friend, so search on Google for Tomcat 6.0 and it will show you were you can get it from.
Take a look at the Apache Tomcat Version Chart here:
http://tomcat.apache.org/whichversion.html
Servlet 2.5/ JSP 2.1 -------------- Tomcat 6.0.10
Servlet 2.4/ JSP 2.0 -------------- Tomcat 5.5.23
Since you want Servlet 2.4 and JSP 2.0 which are required for JSTL 1.1, you could get Tomcat 5.5.x , instead of Tomcat 6.0.x
Although I don't know if Tomcat 6 is backwards compatible with Servlet 2.4 and JSP 2.0 , if it is then it's cool to get Tomcat 6.x
web.xml - Servlet 2.4 Version
<?xml version="1.0" encoding="UTF-8"?>
