[Microemulator-users] Nullpointer trying to open/save RecordStore

[Holger S. <h.s...@ew...>]

Hey peoples


Using: Eclipse Ganymede, JDK 1.6, Maven 2.0.9, Mac OS X 10.5,  
MicroEmulator 2.0.2


I have set up a small maven project within Eclipse for developing a  
MIDlet. Everything was fine so far until I wanted to store/read some  
data into/from RecordStores.

I am launching the Microemultor from within eclipse, with the  
following launch configuration:

Main class: org.microemu.app.Main
Program Arguments: --appclasspath ${project_loc}/target/classes  
com.xyz.MobileTicketControlMidlet

When trying to read/store a RecordStore I got the following exception:

[...]
Caused by: java.lang.NullPointerException
	at  
org 
....microemu 
....app 
....util 
....FileRecordStoreManager.getSuiteFolder(FileRecordStoreManager.java:81)
	at  
org 
....microemu 
....app 
....util 
....FileRecordStoreManager.openRecordStore(FileRecordStoreManager.java: 
114)
	at  
javax.microedition.rms.RecordStore.openRecordStore(RecordStore.java:53)
[...]

This NullPointer is hard to track down, relevant source part from  
RecordStoreManager:

private File getSuiteFolder()
{
	return new File(Config.getConfigPath(), "suite-" +  
emulator.getLauncher().getSuiteName());
}

Hope someone can help! Thanks in advance.
