Hi Jo,

Thanks for your reply.

Our MI runtime is JSP. The detailed requirement is as follows

We need to make this chart available on Intermec iSafe 730 (operating system Pocket PC 2003) and JVM is NSIcom Cre-ME v 4.11.

Application is made using SAP Mobile Infrastructure. JSP is the Programming Model. We are using SAP MI client with SP16 with an Apache Tomcat 3.2.4 servlet engine.

Please let me know if we can create graphs using Javascript for a handheld PC also. Do mail us any sample code if you have any.

Thanks in advance

Hi Jo,

I have gone through details of the link you suggested:

As we can see, that request and response objects are being used for making image and sending it to the Browser.

But , i couldnt find request and response objects in the MAM Code. Are these objects further wrapped in MAM ?

How to access them in MAM code ?

i can just see context object which is being used of getting and setting objects To JSP ( and in turn browser )

Also, i couldnt find any kind of description/Documentation regarding packages ( com.sap.mbs.core.api.* ) like :

com.sap.mbs.core.api.Context

com.sap.mbs.core.api.Forward

com.sap.mbs.core.api.Forwards

Which could have helped in finding things.

Could you please tell any source of documentation/description that exists for such packages ?

Regards,

Vipin.

hello raja,

PocketIE support JavaScript 1.1 in the form of JScript

implementation. VBScript on the other hand is not supported.

regarding the graphs & charts using javascript, you can

make use of some free snippets available on the internet.

however, you have to make sure that the codes are for the

1.1 specification of javascript. just to give you some,

check out the following links for free scripts:

http://artdhtml.com/free/charts.asp

http://www.lutanho.net/diagram/

you can use jsp or servlet to pass the data that are to be

graphed in the browser.

hope this help.

hello vipin,

i had posted the link to the generated javadoc for mbscore

before in other thread. the javadoc doesnt have the descriptions

but it will give you an idea of what classes/interfaces

as well as methods are there.

here's the link.

Hi Jo ,

I tried out the applet tag used in JChart and some other links provided by you.

Its not working on PDA. they are working on desktop versions.

Also, for making line graphs through just javascript - first of all i couldnt find anythign that runs on PDA and also if i would have find out soemthing , it seems a very tedious task to make the entire mathematical calculations and create a line graph in javascript.

So, i guess some third party libraries or some tag libraies would be a good idea.

any hints or suggestions ( for libraries / tags ) ??

Thanks & Regards,

hello vipin,

what type of charts are you trying to plot by the way?

if you are just plotting something like a bar-graph, it

is pretty easy with jsp/servlet. all you need is a 1px

image and an html table codes. in jsp page, you can create

a colums or rows for your bars, and your indicators will be

the image. your image width and/or height will be set to n

values depending on your data... here's a simple example.

blue.gif is a 1px image file of blue color. in this case

your data let's say percentage will be the variable for

the image's height attribute.


<table width="200" height="100" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td valign="bottom" align="center"><img src="blue.gif" width="30" height="20"></td>
    <td valign="bottom" align="center"><img src="blue.gif" width="30" height="80"></td>
    <td valign="bottom" align="center"><img src="blue.gif" width="30" height="60"></td>
  </tr>
    <tr>
    <td valign="bottom" align="center">Data1</td>
    <td valign="bottom" align="center">Data2</td>
    <td valign="bottom" align="center">Data3</td>
  </tr>
</table>

hello raja,

what is your MI runtime? JSP/servlet or AWT?

for JSP/Servlet, you can make use of JavaScript to plot

your graph dynamically. or you can user flash (swf)...

the last resort is to create a jpeg image of the graph

during runtime.

here's a very good article on how to do this.

http://www.javaworld.com/javaworld/jw-05-2000/jw-0505-servlets.html

for awts, either you create from scratch or get commercial

ones... here's an open source one that you might want to

check.
