There is a general feeling that scriptlets in JSP pages are a bad thing.
They can make the page difficult to follow and understand.
The syntax used above was from the JSTL - JSP Standard Template Library : http://java.sun.com/products/jsp/jstl/
The JSTL tags provide a lot of functionality that previously was done in scriptlets.
eg Looping, conditional branching, formatting, XML handling.
Benefits: You don't have to constantly switch between java and html with <% %> tags. The code ends up looking much nicer.
Also it is aimed at page authors, who don't necessarily understand java, but will understand using tags like this.
Myself, I like it because of the first reason - it just makes the page so much easier to read when everything is in tags, as opposed to constantly switching from java to html and back - particularly with braces.
You have to agree:
<c:if test="${params.choice == 'yes'}">
You said YES!
</c:if>looks much better than
<% if (request.getParameter("choice").equals("yes")){ %>
You said YES!
<% } %>Cheers,

Help Business Component JSP Application

I have a problem.
I already have my project with my BC4J Components and my project created using the wizard Business Component JSP Aplication.
But I just created the JSP Pages for one ViewObject.
I don`t know how to add the JSP Pages from another ViewObject in the already created project.
If I try to add a Business Component JSP Aplication to the same project it says me that I have to overwrite the project. I try this but when I want to run the JSP corresponding to the new ViewObject I found the error, that it can`t find the View Object in the Application Module
Please I need urgent help because without this I can't work.

The first page of the Application Module wizard has two windows: Available Views and Data Model. The available views are all the View Objects belonging to your project; the data model shows those view objects you have assigned to the Application Module. [em]You can only generate JSPs for View Objects in the data model [em].
To use a new view object:
(1) highlight it in the available views window.
(2) highlight the anchor point in the data model: for stand-alone pages or master blocks this will be the application module; for detail blocks this will be the master view object.
(3) run the BC4J JSP wizard. you can avoid overwriting already generated JSPs by de-selecting the View Objects from the list. This is a right pain if you have a lot of View Objects in your module. (which is one good argument for having lots of little Application Modules)

Help needed in JSP Expression Language

Hi all,
I have been working for JSP Expression Language Sample execution since past 5 days. I am using the application server as "Jboss Server" and web server as "Tomcat".
I have been included the jsp-api.jar file in my lib directory of application server as well as source folder's lib directory.
When i am trying to build the source code, i am getting this build error.
[javac] D:\eclipse\workspace\esolvProject\development\src\com\esolv\taglibs\
web\classes\SetSupport.java:186: cannot resolve symbol
[javac] symbol : method getExpressionEvaluator ()
[javac] location: class javax.servlet.jsp.PageContext
[javac] ExpressionEvaluator evaluator = pageContext.getExpressionEvaluator();
In my jsp-api.jar , there are two classes called,
PageContext and JspContext, Both are abstract classes.
PageContext inherits JspContext class. JspContext class have the method getExpressionEvaluator() , returns ExpressionEvaluator.
PageContextImpl - class . it has been called internally when we are trying to call PageContext class. In PageContextImpl class, there is one comment before, the method's definition. that is
" Since JSP 2.0 "
But we have the JSP 2.0 version. But it won't work.
Please help me ont this.
Thanks in Advance,
Natraj

>
If the pblm was due to setting the classpath.
The error should be showed for all files in the jar
file.
why i am getting the error for particular method ?
it is accessing the other methods of same class
'JspContext' . but it is not accessing that method.
Thats my question.
Just check that your .jar file is 2.0 compliant and that you do not have any other jars(for servlet or jsp api) in the classpath.
Probably you have an older version of .jar file in your path. So the errors will appear only for those methods that have been added since 2.0, all other methods would compile fine.
Please tell me the jar files to work out the
expression language. so that i can cross check my
list of jars.Hmmm...I dont use jboss. In tomcat the jar file name is jsp-api.jar. But it would have been the same even for jsp1.1, going by jar file names wouldnt help. Just look at your cp as if with a microscope to identify redundant jars.
cheers,
ram.

Help needed- Caller tone application using JTAPI and JMF

Hi to All,
I want to make a Caller Tone Application for Cisco IP phone.
For that application I am using JTAPI and JMF.
I am new to this two technologies.
Can somebody help me for how to accomplish this?

Hi Jerry,
You can run analog input and counter tasks concurrently. You can start them using software timing basically at the same time which may be fine for your needs and is the easiest to implement. You also can use a hardware start trigger to start the tasks if you prefer. It all depends on the level of synchronization you need.
You have not mentioned at what rate you will be acquiring data on your analog inputs. The M Series PCI-6225 has 80 analog inputs and may suit your needs. You will need to know what sampling rate you are trying to achieve. Any M Series device will definitely give you the best value.
Hope this helps!

Help needed with my application

Hi,
Can you take a few minutes and suggest DAQ hardware for my application? I need to measure a high freq signal from a quadrature encoder and correlate it to my 48 analog inputs. I need to know the speed of my motor when the analog measurements are taken. The signal from the quadrature encoder is a 1.7 MHz squarewave ( I can loose some resolution and slow it down ). I was planning on using PCI-6071E but I am not sure if it is suitable any more.
Thanks a lot
Jerry.

Urgent help needed in JSP...

Hi,
I have a variable declared in one of the JSP files. How can I access that variable from another JSP page?
For ex:
jsp1.jsp
<%
String hello = "Hello world!";
%>
jsp2.jsp
<h3>The string is <%= hello %></h3>
I know this code wont work. But how can I fix it?
Please let me know your solutions as soon as possible.
Thank you,
Rajesh

Thanx a lot.
I did understand how to use session to store a java object. Actually, I wanted to use primitive data types... well, I could work around that.
But, could you please explain what you mean by storing in the application context?
Thanks a lot,
Rajesh

Help needed on understanding Application Implementation

I would like to study and document actual implementation steps to implement Oracle Applications, but cannot find any material or courses to help me.
For example:
Conduct client interview to gather business rules
Translate Business rules to Business flow diagrams leading to data flow diagrams
Prepare gap documents
Perform Business Process Re-engineering
etc
Any help will be appreciated

There is an approach called AIM (Application Implementation Method) which you can refer. Details can be found from net or from Metalink.
See if that helps.

Design Pattern help needed for MDI application

Hi,
I am writing an mdi application which contains a JSplitPane. The left pane contains a JTree and the right contains a JDesktopPane which houses n number of JInternalFrames. The JInternal Frames need access to the JTree. Also both panes (objects w/in) need access to elements of the JFrame. I am currently implemeting access by making most of the JFrame objects static and creating getter/setter methods for access. Does anyone know any desing patterns I might use to solve this dilemma?
Thanks,
John

The observer design pattern causes the child objects to chage state when the parent changes state. The type of pattern I need would allow the child objects of the parent JFrame to be available globally without having to make them static. I am wrong in this? Would the observer pattern solve this issue.

Help needed with MIME application

Hi all,
I tried to listen to the radio on my 10.5.2 Mac, as soon as I hit the play button I get this error message that the page has a content of MIME type application and since I don't have the plug-in installed I can't listen to the radio.
Please help, how can I get those application ?

If radio implies iTunes, then post to that forum. If not, provide the details. iTunes radio works here.

HELP needed! N97 Application Installation Problem.

Alright, here's my problem. My friend sent me a .sis program to install in my phone today. When I tried installing the program, it somehow occupied all my available memory in my phone memory (which is about 60MB before I attempt to install the application) and while not able to complete its installation. I suspect that it was a virus program or some sort because when I tried finding for the files in the phone memory through my computer, I failed to find any file which has that amount of size. My computer only shows that a total of 19MB files are contained in the phone memory but somehow I don't even have a single KB of space available in it. (it's hidden somewhere or some settings are altered i guess)
Please do help me in this issue. Any help would greatly be appreciated.
Thanks alot.
P.S. just bought my phone a week ago

I've tried Y-browser and Xplorer but it seems that no hidden files is of that size. And about the anti-virus, can I have the specific name for the program?
It would really do me a great favor if you can tell me where does all the temporary installation files are located when installation runs its progress on the phone.
I've considered hard resetting but I'm unsure of the effect after doing so. Will it wipe out all my data and settings in both phone and mass memory (C: and D?
Thanks in advance.

HELP NEEDED!! application and theme problem in n93...

hey.. i encountered a few problems in my n93 which i just purchased a few days back..
There are 2 major problems that really frustrates me..
first, when i install a theme in the memory card and use it, the theme gets resetted to the default theme(blue one)everytime i off and on the phone..But when i install it to the phone memory everything is fine..
secondly, when i install an application(eg agile msngr) in the memory card, it works fine. Then when i reset my phone(off and on), the application cannot seem to work.. i try to open the application but nth seems to happen.. however i found that if i ejected and inserted the sd card(when the phone is on) the application works..But when i install it to the phone memory the application works fine..
The same also happens to the mobile filmmakers application installed in my memory card..
ive tried to reformat the memory card but everything is still the same.. the problems still occur..
How do i solve this problem??? i do not want to rely on phone memory for all my applications and themes.. the internal memory of 50mb is not enough..
HELP!!

Hello, I have the SAME problem, though I didn't see that installing applications to phone memory they keep working fine.
Of course I also want to have them working on memory card for space reasons.
I have recently (after LONG waiting) updated firmware to 20.0.0.58, but the problem is still there :-(
I am sure that asking Nokia help on-line will cause the usual "contact closest assistance point"....
which firmware version do you have ?

Since i just copied it from another well functioning coding i didn't check for typos in the coding. Maybe i accidentally pressed something on the keyboard.
Thanks for the help guys..I really appreciate it.
