I get this dialog box when I try selecting Preferences in the emulator (S60 3rd). What seems to be wrong?

I'm only starting to make my first program.

Do you have the required JRE version installed ?

Only the latest, Java 6 SDK. Won't it work?

downloaded jre 1.4.2, and it worked. thanks for the tip.

I get the same error message but I have both JRE 6 and JRE 1.4.2_13 installed, do I need to uninstall JRE 6 to make it work?
Thanks

I didn't have to uninstall jre 1.6... just check if 1.4's in the path.

You do not need to install jre 1.4.2. You can even work with the latest java installation 6.0. However, you need to modify config.properties file for the series 60 installation. Open the file <installation_path>\Epoc32\tools\ecmt\config\config.properties and add the version of jre for the parameter epdt.java.version.start.

For JRE 6.0, you should add:

1.6,6.0

,so that the line seems like:

Worked for me. I was going through the hassel of configuring multiple JREs when I noticed this suggestion.

Thanks for the tip,

hi all,

I am having same "Cannot start ECMT Manager" problem and tried to solve it by adding version no. suggested in this thread without any success.

I want to connect MIDP emulator to real S60 device.

- I have S60_3rd_ed_SDK_FP2_Beta installed on my system.
- I have three JREs installed on my system of following versions
1) 1.4.2_05
2) 1.6.0_03
3) 1.6.0_03 (this is part of JDK 1.6)
