MGMaps and the Blackberry JDE

Make sure that you use RIM version of the library (rimui_maps_lib-0.10.0.jar), no the default one.

In the RIM version there are no methods mentioned in your log, as it is not obfuscated. Also make sure that you do not obfuscate (at least not with proguard) your application, as BB does not like it.

Hi Jaak,

I am also still trying to get the j2me version of this working to compare which version we would like to use. I have done as you suggested and tried compiling using the rimui...jar. However, when I do that, I get a compile error because it says that com.nutiteq.MapItem is not available.

Am I supposed to use a MapComponent even if I am building it as a Midlet when using it on the Blackberry?

Please note that this is different than some of my other questions where I was using the RIM version with a UIApplication. In this case, I am trying to build it as a MIDlet for the BB.

Thanks,
Eric

You are right, there is this limitation. We will build special RIM MIDlet library JAR for the next version update.

Current workaround would be to use the library source. For BB it needs some manual changes: removal of non-RIM classes (mainly file systems). See http://www.nutiteq.com/content/using-source-code-blackberry#comment-54 about it. In your case do not remove MapItem.java, and do not change references to .lcdui to rimui.

Let me know it this works.

Hi Jaak,

Do you have any documentation on which libraries to include in the classpath to compile from source? I grabbed many of the latest versions of the other packages that I could find, but I am getting compilation errors. Do you have a list of jars and their version? Or, some other type of documentation for building from source?

Below are the compilation errors that I am currently receiving. (sorry for the long post)

Thanks,
Eric

There are actually no extra libraries needed besides the standard MIDP 2.0 and CLDC 1.1 libraries. All the other is in the source. From the errors I see that you should have removed following classes:
/com/nutiteq/helpers/BluetoothGpsBrowser.java
/com/nutiteq/utils/fs/FileBrowser.java
/com/nutiteq/utils/fs/FileBrowserListener.java
/com/nutiteq/utils/fs/IDENFileSystem.java
/com/nutiteq/utils/fs/MotoFileSystem.java
/com/nutiteq/utils/fs/SiemensFileSystem.java

This is the first thing to do. Of course this means that you also cannot use the classes in the case of RIM MIDlet.

Also make sure that source path includes also the third party sources which are included with library (thirdparty/src directory). Eg. Float11 is from there.

The recently released new lib version has separate zip package for Blackberry. You'll find two jar files from that: one for "rimui" (CLDC apps using UIApplication) and another one for the midlets in Blackberry.

These are the results from Building the example off the web in J2MEPolish for Blackberry 4.7

It dosen't work.
