Can somebody explain to me how JSP, servlets, ASP work within Sun's server

Ok, I'm only beginning to get a grip of how all this works. And I have a lot of questions and confusion.
1.) The server that comes with J2EE, what is that server? Is it an app server that runs only servlets and JSP, with some Web server stuff so it can output some info? Is it a stripped down version of TomCat? I am having a lot of trouble with the J2EE server (the one that comes with the SDK), and that is why I'm asking, maybe I don't need it. But I really want to learn JSP's, JScripts, and Beans. How else can I go about doing that, other than all out Tomcat.
2.) Also can I run Servlets on Microsft's IIS on a Windows 2000 machine? Do I need a special API to run servlets, or JSPs?
So how I see it, and again, I am a newbie at this. Machines that host a website, above all needs a web server. let's say most people use Apache, and they want to run it in Linux, becuase they want to be hackers. So then do they also run Tomcat, or IIS, or Coldfusion, or a million other servers in tandem on the same machine, so that they can handle ASP, JSPs, servlets, .cmf, etc.? or do they separate the app server from the webserver and then do some sort of linking? if somebody can direct me to how all this stuff works, I would greatly greatly appreciate it.

Sounds like you need to read the J2EE spec as well as
the servlet and JSP specs. It helps to glance through
sections you are interested in.

I think for a newbie, deploying your jsp's and servlets
to a J2EE compliant app server can be quite a headache.
You might want to concentrate on tomcat, which does servlet
and jsp.
Some app servers provide a http connector for most common web servers.
I think tomcat has a IIS connector. In this case IIS would serve static html as well as its own stuff, other things like servlets and jsp go to tomcat. I am unsure about this as I mostly use tomcat in standalone mode. You can run tomcat on windows, as it is written in java.

Can somebody explain to me how I can detect that an internet connection exists (VB)?

Can somebody explain to me how I can detect that an internet connection exists (VB)?

There is no reliable way. Better test whether you can go to where you want to go. And be prepared to support proxies, even the complex ones that require authentication.
System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable reports your local connectivity regardless of whether one of your connected networks has Internet access.
Microsoft's Network Awareness API (the one used in control panel\network and sharing center) use a connection test to a web site setup by Microsoft. But your customers could be behind cooperative firewalls that make this test unusable even when Internet
access is available though other means (e.g. via a local proxy server). If you want to connect to your own web site, then you can skip that and just connect to your web site instead. Even if you were able to connect to Microsoft's web site there is no guarantee
your web site would be accessible in the same network.

Can somebody explain to me how java and xml are related?

Hi guys
im new to java and xml.Been reading a lot regarding java and don't seem to have a problem with it...
the problem is the xml part...im doing a simple GUI project using swing(online store) and i have to convert it to xml
I have absolutely NO IDEA why i must convert my java to xml and have no idea how to do that.I been reading on the net that xml is a exten~ markup language and it is better and useful.
Can somebody explain to me in layman terms
1)how is java and xml related in?
2)why do ppl want to convert java to xml when they can just stick to java
3)what is actually xml...
4)Do i need a program to create xml like i need jcreater to create java application
5)How do we actually convert?is there any links that you guys could tell me?
thank you

im new to java and xml.Been reading a lot regarding
java and don't seem to have a problem with it...Okay.
the problem is the xml part...im doing a simple GUI
project using swing(online store) and i have to
o convert it to xmlYou have to? So presumably somebody in a position of authority told you that?
I have absolutely NO IDEA why i must convert my java
to xml and have no idea how to do that.I been reading
on the net that xml is a exten~ markup language and
it is better and useful.I have no idea either (besides which, it doesn't make sense). But why ask us? Somebody told you to do that, ask them why.
Sure, XML is useful. But it isn't a programming language so it can't be used as a substitute for Java.
Can somebody explain to me in layman terms
1)how is java and xml related in?They aren't related, except perhaps in that they are both used in computers.
2)why do ppl want to convert java to xml when they
can just stick to javaThey don't.
3)what is actually xml...Start here for numerous definitions:
http://www.google.ca/search?hl=en&lr=&oi=defmore&q=define:XML
4)Do i need a program to create xml like i need
jcreater to create java applicationNo, XML is just text. But then Java code is just text too.
5)How do we actually convert?is there any links that
you guys could tell me?You don't convert Java to XML. My guess is that because you don't know much about Java or XML, you have misinterpreted something that somebody told you.

Dear Song,
Answers to your queries are given below:
Sample function module:
u2022 Is only used as a template for creating the standard function modules to be carried out
u2022 Defines the interface that is binding for the standard function modules
u2022 Describes in its documentation what the underlying event can be used for
Standard function module:
Name of application-specific standard function module that can be carried out at a given time.
The standard function module interface corresponds to the sample function module, which it must match exactly.
Active function module:
Function module which is to be called for the specified event.
If you don't want to take printout then use Functional module 340 as Event 0340 is called when all data is read for a dunning notice.
You can use standard function module FMCA_DUNNING_READ_ITEMS_0340 for this purpose.
Hope it will solve your query.
Warm Regards

Can somebody explain how ABC analysis is done ?

Hi Experts,
                     Can somebody explain how ABC analysis is done . If I use MC40 transaction there I have 4option but I can use either one of those . For second option , Usage value as number we can directly specify cost and accordingly system will classify materials In A, B and C category .
I have question on 1st 3 rd and 4 th option . How system will classify materials if These option is used .
Please explain with examples .
Points will be rewarded .
Thanks in advance !
Neal

Hi Sir ,
                 Thanks again , I would explain what I have understood .
MC 40 . Option selected is Usage value with value put are 70 , 20 , and 10 .
Suppose I have 3 mat in plant
              Stock         Value
1) X        100 kg      1000   ( for 1 kg from MM)
2) Y          20 PC      2300
3) Z          30 lt      40000
Now how would system classify these items ? Will it consider price or only consumption /qty ? or both ?
Please explain with the same figures . Again the 90 days period you said , is it taken automatically ? because on this T code there is no option for entering time period .

Can't get EntityManager access in JSP/Servlet

Hi all,
our team has started a EJB project (EJBs + JPA configurations)
we managed to access the configured JPA (EntityManager etc) within the EJB instance; however we don't know how to access the EntityManager within JSP/Servlet
Our project's structure:
1 EJB project (EJB classes, EntityBean classes, JPA configuration + eclipselink)
1 Web project (for JSP, Servlets)
the main problem is ... we can't access EntityManager(s) in JSP / Servlets (and we already tried using Struts2.0 to replace servlets/jsp... the problem is the same... so it is not ... the matter of choosing the view technology...)

My new I5 uploaded doubleded all the songs from my library! Please, can somebody help me showing how can I delete just the songs that was doubled?

Hi there everybody,
My new Iphone 5 uploaded doubleded all the songs from my library! Please, can somebody help me showing how can I delete just the songs that was doubled?
Some help will be greatly appreciate.
Thanks much!

When you say "account," do you mean your iTunes library, because your iTunes library is what is on your computer? Your iTunes library does not have an email address. An account that is related to iTunes is your Apple ID (which is an email address) and you use it as your user name to sign in to the iTunes Store, to make purchases. Changing your Apple ID will not make songs disappear from your computer's iTunes library.
If you had an Apple ID and used it to make song purchases from the iTunes Store, and then started using a different Apple ID, you should be able to re-download the songs purchased with the old Apple ID. In iTunes, sign in to the iTunes Store using your OLD Apple ID (and password). That may not be your current email address, but Apple uses it as your user name, so it does not matter.
On the iTunes Store Home screen, click on Purchased under QUICK LINKS. This takes you do the Purchased screen, where you can re-download previous song purchases (for that Apple ID) at no cost.
NOTE: If those song purchases are from more than a few years ago, you may also need to authorize your computer to play (and sync) songs for your old Apple ID.
For songs that were not purchased from the iTunes Store, if they are also gone, you cannot get them back unless you have a backup (or they are still loaded on your old iPod).
If that's not what you mean by "changed the email address on my account," please post back with more details.

In the print window select a print size that would allow many of the same photos on the page. Click the Customize button and under settings select Multiple of the same photo per page. In this screen shot I selected a size of 2x2.
Adjust the print size to get the number of photos per page that you want.

Can you explain me clearly how to make company code visible in cost center

can you explain me clearly how to make company code visible in cost center master data using tcode kmlv

Hi,
There is no way to activate the company code field. If your Controlling Area and Company Code have one to one Assignment, then Company code is defaulted from the Controlling Area. However, if multiple Company Codes are assigned to one Controlling Area, then Company Code becomes a mandatory field in the Cost Center master data
Also, in case you have multiple company codes assigned to one controlling area, please check the setting of the Controlling Area in Configuration and see if have selected "Cross Company Code Cost Accounting" . Also, check if you have assigned all the company codes to the controlling area

Can somebody explain what the Radix number is in Character

I am looking for a good way of converting numbers to characters and I was reading up on the Character API, and they are using this term Radix, and I don't understand what that is all about. Can somebody explain what the radix is for?

Wait a second I tried this code out and this is the output
System.err.println(Character.digit('a', 10));and i get a -1, which means "not a valid digit in the specified radix.
Then I tried other combinations like
System.err.println(Character.digit('a', 11));
System.err.println(Character.digit('b', 12));
System.err.println(Character.digit('c', 13));and they all work, and but with only those sequential characters and numbers. So right now I am very confused as to what this radix, or this function serves. Can somebody explain?
