How to add the API to the project?

[schumi1331]

Hello,

I downloaded the Maps API (0.5 from the Wiki) and would like to add it to my project.
I've done this in Netbeans via Project Properties > Build > Libraries and Resources and there adding the nma.jar. But it doesn't work as it shows me this when compiling:

E:\GemeinsameDateien\VRSFahrplan\Tankometer\src\Main.java:7: package com.nokia.maps does not exist
import com.nokia.maps.*;
1 error

Is there anything else I need to do to be able to use the API?

Best Regards,
Sebastian

Basically the Add Jar/zip option would be the only thing you need to do, all and all I would suggest you would try the 1.0 version, it available now at: http://www.developer.nokia.com/info/...3e/JavaME.html

thanks for reply

I used now the new version of the Maps API, but I still get the same error when compiling...
Also when adding "import com.nokia.maps.*;" into the source code in Netbeans it shows the message, that the package doesn't exist...

(if it should be important, I'm using Netbeans 6.9.1 with Symbian Belle SDK v0.6 on Windows XP SP3)

would be happy about every idea

Can you run it in the simulator ? I'm now on my home computer, and to check the java environment, I would need to use my office computer, which I could only check tomorrow morning.

[schumi1331]

I'm working in VirtualBox, because of what I'm not able to run the emulator (see here: http://www.developer.nokia.com/Commu...ice-quot-error)...

so I can't give you an answer to that... :/

maybe you could simply select the Nokia SDK 1.0 for Java option, i.e. run it in the simulator. For device you could see whether the ticking all optional packages would help. Gotta admit that I have not tried running any java apps on Symbian emulators.

[schumi1331]

running J2ME app in the Symbian Belle emulator works very well, as I'm using it on my desktop PC with Windows 7...

I don't think that this is the problem why it doesn't find the package...

[symbianyucca]

Anyhow, as said you could always try the SDK simulator or real device, those I have also used, so they should work just fine.

[schumi1331]

you're right, but it's not possible to use any simulator or real device, if I'm not able to compile the app because of the non-existing package com.nokia.maps...

[symbianyucca]

So just to make sure, you did this:
1. right click teh project, and click Properties from the pop-up menu
2. select Libraries & resources
3. Click Add jar/Zip
4. Browse to find the nma.jar file and click Open,
5. See that it is added to the list
6. click Ok

Then you should be able to build & run it.

[schumi1331]

yes, that's what I've done, see here:

looks pretty much ok to me, anyway can you try the helloworld examples from our wiki: http://www.developer.nokia.com/Commu...PI_for_Java_ME

[schumi1331]

hm, that's interesting: the example from the wiki works without any problem...

so I tried something and pasted the import task from the example into my project source file, and it also worked...

so why does this work:
import com.nokia.maps.map.MapCanvas;
import com.nokia.maps.common.*;

and this not:
import com.nokia.maps.*;

?

this is the error when trying to compile it with Symbian Belle SDK...
when I compile it with Symbian 3 SDK everything works fine...

It looks like your set-up is failing to find the SAX Parser on the classpath. Here are a few things you could try:
1) Try adding the Web-services optional package jsr172 to your project.
2) I guess you don't have this problem if you don't obfuscate. but you could reduce the obfuscation level
3) add -libraryjars \path_to_my_SDK\jsr172.jar in the additional obfuscation settings.
