Map in midlet
Hello
Currently we are writing a midlet and there's a requirement that the midlet should integrate a map. The map should work in offline mode, so yahoo map and google map is useless here. I should install the map with my app and draw it. I couldn't find any helpful information on the net. Anyone can give me a hint?
Thanks in advance :)
no one can help? :(

Java.lang.ClassNotFound Exception whenever I include .send()
Everything runs fine, but when I add the .send(message); [it is in bold] I get a java.lang.ClassNotFound Exception.
It still compiles, it just won't allow me to launch the program in the emulator. If I take that one piece of code out, everything runs fine again. I've been messing with it, and searching for a long time in an attempt to solve the problem but I've yet to come across a solution.
I'm also using Bluej

}Hi,
I had this problem in KToolbar which is the utility shipped with J2ME and what i had to do was make sure that KToolbar was looking for the main class to load, which in yours would be the ListDemo.class. i havn't used the netbeans utility but (if you can) make sure the main class is listed. (it might be in the project settings).

Blackberry controls and midlets
Midlet meets blackberry let the battle for who can use the escape key begin!
If you're having trouble mapping keys from the blackberry to your midlet..this will definitely help you!
in this post I go over: Adding menu items to the blackberry menu, and gaining access to undetected keys such as the Escape Key.
First of all, that **** menu how do I add stuff to it?
Well...that in itself is a hastle but lemme just say, that menu
is in a nutshell a CommandListener. Same freakin menu. Later on in this post I show how to map the escape key..and i'm guessing pretty much every other key...of course
the only key I ever had a problem with was the EscapeKey/HangUpKey
Anyways if you want that BlackBerry Menu Code here

}now keep in mind, I took this from a nice little example MIDlet called DemoMidlet inside the BlackBerry JDE
so it's not like they didn't make an effort. I mean I pretty much took it out of their examples located in
C:\Program Files\Research In Motion\BlackBerry JDE 4.6.0\samples\com\rim\samples\device\midletdemo
but lets face it...some of us like to use the Canvas Class...so showing us how to use it with a Form not exactly helpful.
All I did was the same thing it's just I made a canvas, and implemented the CommandListener, then swapped their form for my canvas.
It freaking worked like a charm. I mean I didn't really use that alert stuff...as it wasn't necessary, but it's a nice demo to learn from.
Part 2: The Escape Key!
The first and only problem I noticed when porting over to the blackberry was the lack of certain keys
that I truly enjoy and need. I guess blackberry decided to just not implement them
into the MIDlet canvas class?
I mean they did a great job at figuring out how to map the entire qwerty keyboard, but when it comes to the Escape Key
good luck!
So after tearing my hair out I found a solution...which i'm guessing everyone else also found but i'm posting this
cuz well..what if you're tearing your hair out right now...calm down take a deep breaths this is currently working on the BB 9000
jde emulator.
First of all I know this sucks but if you want to use that lovely escape key you're going to have to implement the BB KeyListener.
I know WTF MAN!? "first i code the whole thing using keylistener/commandlistener now I gotta use some stupid BB KEYLISTENER!?...just who does blackberry think they are?"
well heres the thing, I tore my hair out for like 12 hours straight trying to get around this...but after giving it a rest it's not such a big deal.
Steps
1) you have to grab the blackberry net_rim_api, and add it to your wireless toolkit.
the path is:
C:\Program Files\Research In Motion\BlackBerry JDE 4.6.0\lib\net_rim_api.jar
what I did was copied the file and pasted it into
C:\WTK2.5.1\lib\ext
once you have that inside your ext folder in your project settings you can enable the external package, this way you can build
using the RIM API.
in case you wanta take a glance at that headache it's : http://www.blackberry.com/developers/docs/4.5.0api/index.html
to enable it simply open up wtk, go to project/settings/External API's and check it off...take note that the wtk 2.5 generally comes with
Nokia SNAP Mobile API so i'm guessing it's a normal thing to do with MIDlets. Also if you check off Bundle..that's not too good it includes the API
with your package...which is really only helpful if you're trying to include some of that junk which really isn't necessary as the reason we're doing this in the first
place is cuz blackberry wanted to be cool and have their own proprietary keys....
Anyways check that off and continue to step 2.
Implementing Key Listener with the Canvas Class! :-)
2) This part is so easy...
import java.io.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
import net.rim.device.api.system.*;
public class myCanvas extends Canvas implements CommandListener,KeyListener{
String thekey = "no key pressed yet";
public myCanvas() {
Application.getApplication().addKeyListener(this);
public void paint(Graphics g){
g.setColor(255,255,255);
g.fillRect(0,0,500,500);
g.setColor(0,0,0);
g.drawString(thekey,0,0,Graphics.TOP|Graphics.LEFT);
public boolean keyDown(int keycode, int time)
thekey = String.valueOf(keycode);
repaint();
return false;
public boolean keyRepeat(int keycode, int time)
return false;
public boolean keyStatus(int keycode, int time)
return false;
public boolean keyUp(int keycode, int time)
return false;
public boolean keyChar(char key, int status, int time) {
if (key == Characters.ESCAPE)
return false;
public void commandAction(Command c, Displayable s)
///YOU DON'T NEED THIS! I just left it here, in case you wanted to also use the blackberry menu to do stuff...in this case
//well the command is shown...and it calls the run method of the class you add the command to. My previous example
// used the command GO, and i made a private class...so this would cause the run method to execute when the user hits enter on go.
// if ( c instanceof Runnable )
// ((Runnable)c).run();
}i'm gonne be honest with you, the function public boolean keyChar()
I don't know if that actually works...I just don't want to recompile without it cuz I just got over this headache..so I left it there.
According to most people you use that to check if the key == Characters.ESCAPE and if it does then you do some stuff.
Also you don't need the command listener, I just left it in there because well..if you're like me and you use the blackberry menu, you're pretty much
going to use the CommandListener on your canvas to check to see if the user hit enter on a menu item.
The function that matters here, is the same function Midlet coders are used to.
instead of keyPressed it's simply keyDown
so basically you're importing the package
import net.rim.device.api.system.*;
which allows you to implement blackberry's keyListener which gives you access to all the keys vs. a limited amount of them.
now blackberry went all out as you can see. You have to have keyDown, keyUp, keyRepeated...it's kinda rediculous.
but no worries, as long as you make sure that Display.setCurrent(yourcanvas);
or you use one of those to give the canvas control...you'll be fine.
It works because in the method for creating myCanvas()
or whatever canvas you'll be using, it calls Application.getApplication.addKeyListener(this);
and that little command gives your canvas the ability to listen for blackberry keys such as escape.
the current code will start displaying the keycodes for each key...and apparently keys such as ESCAPE
can be labeled properly. I love this because I can map the hang up call key to destroy my midlet, or even the escape key.
Unfortunately every keycode displayed is in like unicode or some stupid format, so that's my guess as to why the Escape key is not detected by the normal
canvas keyPressed method.
Anyways you're done this should work...now if you're having trouble using canvas and you're like "but I don't use canvas" idk man...
I use canvas...cuz I think programs should look cool. I'm sure this works without the canvas...on a form or something.
But don't be fooled, you're not limited to KeyListener, you can also use TrackWheelEvent and all kinds of stuff. So just like the choices for CommandListener vs. keyPressed
Blackberry has other choices as well.
And they said merging the API's was a bad idea...shucks, how else are we supposed to use the freaking escape key.
--JavaLover53
P.S. I marked this as a question cuz I want people to really take a look at this. Make some comments, I love this forum
and I really feel that this topic is not covered on the internet. A lot of naysayers, and when I found the solution I was like "that's it"
"that's all I had to do?" "well then wheres the freaking tutorial!
seriously people had me thinking I had to extend the blackberry UI when this is all I had to do..such an easy task
that other people claim is ridiculously hard.
Go ahead make your comments, lemme know if you know something I don't, i'm here to learn! :-)good writeup, however i found this only working when you're not running fullscreen

No Midlet Suites Found. Check the URL to make sure it is correct
hi,
i am very much in need of solution so plz respond as early as possible
i am trying to simulate OTA provisioning through J2ME Wireless Toolkit for this i am using Apache HTTP Server Version 1.3
i placed the .jad files and .jar files in htdocs directory and i added the below two lines to httpd.config file
AddType text/vnd.sun.j2me.app-descriptor .jad
AddType application/java-archive .jar
i changed the MIDlet-Jar-URL property in .jad file to point to .jar file
i restarted the Apache server and started the toolkit when i pointed to the .jad the error i got is "No Midlet Suites Found. Check the URL to make sure it is correct"
can any one help me out in finding what i missed in the process of installing the midlet suite through OTA provisioning in the toolkittry adding these lines in the configuration file as applicable to your server
<mime-mapping>
<extension>jar</extension>
<mime-type>application/java-archive</mime-type>
</mime-mapping>
<mime-mapping>
<extension>jad</extension>
<mime-type>text/vnd.sun.j2me.app-descriptor</mime-type>
</mime-mapping>
Also, check if your JAD file contains the following information
MIDlet-Jar-URL: http://<server_ip_or_name>:<port_if_other_than_80>/<context_root>/<name_of_your_file.jar> -
Hi! I need help for a school project. The idea of the project is that users can upload a map (an image), supply the necessary information (to be stored in a database), so that other users can download the map and view it on their mobile phones. Example, the users can select which map to download and run on their phones.
I was wondering if you have any ideas/suggestions on how best to do this project.
Many thanks in advance...The desktop should only allow map editors to upload a map and supply map information. I was wondering if it's possible for the desktop application (made from regular java) to generate a midlet (made from Java ME?) so that the generated jar/jad file could be run on mobile phones.
What I'm trying to do is like this project: http://www.cs.kent.ac.uk/pubs/ug/2005/co600/mobimap/Technical%20Report.pdf
except that users can choose which map to run on their phones from maps that other users uploaded on the desktop. -
I'm trying to design and develop an application which uses Location Based Services and basicaly shows an interactive map of the current location.
I would like to ask if anyone knows where to start, I know more or less how to use JSR-179. Let's say I have current coordinates and then I want to display the map, the point is I would like to know which way to go from here.
The Google Maps API is fairly easy if you use Java Script and a web browser, does anyone know how to get the map from google or maybe yahoo and display it in the midlet without the browser?
There is a midlet available straight from google (mobile goolge maps http://www.google.com/gmm ) which is just great, I have no idea how it is implemented, If anyone knows, please send me some suggestions.
I would like to accompish all the processing of the retrived images(possible from the google maps server) with Java EE and then retrive them and display them on the mobile (maybe as an XML file - SVGt image). Anyway, I hope I have described the idea, as I said I don't know where to go, and if there is someone with some experience with that kind of staff please help, this is my final year project and I'm not asking for the solution, just for some directions and the proper way of implementing those things.
Thanks a lot in advance!You can use the Yahoo Maps API. It has a REST interface.
http://developer.yahoo.com/maps/rest/V1/mapImage.html
You can parse response and download the image.
Alternatively you can use a server as an intermediary. For example, you can send your server the coords and options, then your server would talk to Google or Yahoo and retrieve the map image.
I created an example app some time ago that will use the Yahoo Maps image. The project page is http://gallery.yahoo.com/apps/10685 and the source code is available on http://hostj2me.com/appdetails.html?id=2875
It takes up to minute to initialize and retrieve the initial coords. But here is how it works.
1) get GPS coods
2) send cords (http get) to Yahoo
3) parse XML response and retrieve image URL
4) download and display image from URL -
Anyone using openstreetmap and mapviewer/mapbuilder to create maps
anyone using openstreetmap and mapviewer/mapbuilder to create maps?
Ok, I do exactly as you specify here. In addition I import the needed jars from the import folder of j2mepolish. Also, I put the resources folder from the polish sample (MenuMidlet) in the project, and all marked errors disappears.
Then I try to run it as an Ant build, and get the following error:
BUILD FAILED
D:\Program Files\eclipse31\j2me\sample\build.xml:115: The MIDlet [source.src.de.enough.polish.example.MenuMidlet] could not be found. Check your <midlet>-setting in the file [build.xml] or adjust the [sourceDir] attribute of the <build>-element.The MIDlet should be in D:\Program Files\eclipse31\j2me\sample\source\src\source\src\de\enough\polish\example\MenuMidlet.java
Ok - so it seems that it for some reason gets "source\src" two times. So I go back to the <midlet class and remove the source.src, leaving just de.enough.polish.example.
Then I run as Ant again, and it compiles successfully.
However, when I try to run the MenuMidlet class as a j2me midlet (in eclipse) it starts, and then crash with this error:
java.lang.NoClassDefFoundError: de/enough/polish/util/Locale
at source.src.de.enough.polish.example.MenuMidlet.<init>(+11)
at java.lang.Class.runCustomCode(+0)
at com.sun.midp.midlet.MIDletState.createMIDlet(+19)
at com.sun.midp.midlet.Scheduler.schedule(+52)
at com.sun.midp.main.Main.runLocalClass(+28)
at com.sun.midp.main.Main.main(+116)
So - seemingly - to compile it I need to give it one address, but for the midlet to run it must be compiled with an address that won't let it compile :-)
Well - then I create a J2ME package from the project, and run the deployed/sample.jad file. Then the midlet actually starts, but when I click Launch, the display shows:
New Midlet de.enough.polish.ui.MenuBar Exception: java.lang.classNotFoundException: de/enough/polish/ui/MenuBar
I can't find a reference to MenuBar anywhere in the sample code. -
Is signing Compulsory for midlets?

Ravi varmaXI is a middleware from SAP that is needed to connect to other SAP systems like SAP R/3 or non SAP systems.
Now for SAP Auto ID Infrastructure scenarios where integartion is to happen to the SAP R/3, the config guides by SAP has taken XI as the middleware.
However, XI is not at all compulsory to integrate to R/3. Any other middleware that can map from AII to R/3 or other systems can be used with AII.
But if you are looking to configure the standard flexible delivery scenario from AII then its better to work with XI as SAP clearly details the steps needed to configure the solution in their configuration guides.

Remote System and Remote Key Mapping at a glance
Hi,
I want to discuss the concept of Remote System and Remote Key Mapping.
Remote System is a logical system which is defined in MDM Console for a MDM Repository.
We can define key mapping enabled at each table level.
The key mapping is used to distinguish records at Data Manager after running the Data Import.
Now 1 record can have 1 remote system with two different keys but two different records cannot have same remote system with same remote key. So, Remote key is an unique identifier for record for any remote system for each individual records.
Now whenever we import data from a Remote System, the remote system and remote key are mapped for each individual records. Usually all records have different remote keys.
Now, when syndicating back the record with default remote key is updated in the remote system that is sent by xml file format.
If same record is updated two times from a same remote system, the remote key will be different and the record which is latest contains highest remote key.
Now, I have to look at Data Syndication and Remote key.
I have not done Data Syndication but my concept tell if there is duplicate record with same remote system but different remote keys both will be syndicated back. But if same record have two remote keys for same remote system then only the default remote key is syndicated back.
Regards
Kaushik BanerjeeYou are right Kaushik,
I have not done Data Syndication but my concept tell if there is duplicate record with same remote system but different remote keys both will be syndicated back.
Yes, but if they are duplicate, they needs to be merged.
But if same record have two remote keys for same remote system then only the default remote key is syndicated back.
This is after merging. So whichever remote key has tick mark in key mapping option(default) , it will be syndicated back.
Pls refer to these links for better understanding.

SebastianThese type of Internal Errors are all too common in OWB and it's difficult to diagnose the exact problem.
I'd suggest closing the Design Centre, going back in and trying to delete it again, this will often resolve Internal errors.
There's also an article on Metalink Doc ID: 460411.1 about errors when deleting mappings but it's specific to an ACLContainer error, so may or may not be of use.
One of the suggestions is to connect as the Repository Owner rather than a User and try to delete the mapping.
Cheers

Dear SDN,
In an integration scenario we are using sender File Adapter and a ABAP XSLT Mapping.
Is there any way to get the source FileName from such mapping. Im trying to use the adapter-specific message attributes, but it doesn't work, and I didn´t find an example, probably I and doing somthing wrong.
regards,
GPThank you for your help,
I just try to access the adapter-specific attibutes using:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:key="java:com.sap.aii.mapping.api.DynamicConfigurationKey">
<xsl:variable name="filename" select="key:create('http://sap.com/xi/XI/System/File', 'Directory')" />
</xsl:stylesheet>
but the following error raised:
<SAP:Stack>Error while calling mapping program YXSLT_TEST (type Abap-XSLT, kernel error ID CX_XSLT_RUNTIME_ERROR) Call of unknown function</SAP:Stack>
have you had this situation? -
Sample source code for fields mapping in expert routine
Hi All
Iam writing the expert routine from dso to cube for example I have two fields in dso FLD1,FLD2
same fields in infocube also ,can any body provide me sample abap code to map source fields to target fields in expert routine,your help will be heighly appreciatble,it's an argent.
regards
eliazBasic would be ;
RESULT_FIELDS -xxx = <SOURCE_FIELDS> -xxx
you have the source fields as source, and result fields for as the target. In between you can check some conditions as in other routines of transformation.
BEGIN OF tys_SC_1, shows your source fields ( in your case DSO chars and key figures)
BEGIN OF tys_TG_1, , shows your result fields ( in your case Cube characteristics)
Hope this helps

How can I distinguish different action mapping in one ActionClass file?
I would like to create a ActionClass which will handle 3 mapping which comes from /add, /show or /del.
My question is how can I change the code so that the ActionClass servlet can distinguish the request from different url mapping ? Can anyone give me some short hints? Thx.
struts-config.xml
<action-mappings>
<action name="MemberInfoForm" path="/add" scope="request" type="com.myapp.real.MemberAction">
<action name="MemberInfoForm" path="/show" scope="request" type="com.myapp.real.MemberAction">
<action name="MemberInfoForm" path="/del" scope="request" type="com.myapp.real.MemberAction">
</action-mappings>MemberAction.class
public class MemberAction extends org.apache.struts.action.Action {
private final static String SUCCESS = "success";
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
return mapping.findForward(SUCCESS);
...http://struts.apache.org/1.2.x/api/org/apache/struts/actions/MappingDispatchAction.html
http://struts.apache.org/1.2.x/api/org/apache/struts/actions/DispatchAction.html
Thank you so much for all of your suggestion.
I read the document of MappingDispatchAction and its note say:
NOTE - Unlike DispatchAction, mapping characteristics may differ between the various handlers, so you can combine actions in the same class that, for example, differ in their use of forms or validation.........
I wonder in DispatchAction, we can also have various forms or validation as MappingDispatchAction does, just by using different name in the action tag, for example:
<action input="/p1.jsp" name="MForm1" path="/member" scope="session" parameter="action" type="com.myapp.real.MemberAction">
<action input="/p2.jsp" name="MForm2" path="/member" scope="session" parameter="action" type="com.myapp.real.MemberAction">
<action input="/p3.jsp" name="MForm3" path="/member" scope="session" parameter="action" type="com.myapp.real.MemberAction">Hence, it is not the difference as stated from the NOTE, right?
