Could not find the main class: org.yccheok.jstock.gui.MainFrame. Program will exit.

1.0.7.L is starting well. Beginning with 1.0.7.m the posted error above is coming.
I am using the Linux .jar File under ecomstation 2.1 and java 1.6.27

[warpwe]

I found the reason for this error.
The code is compiled for JAVA 1.7 but I have only JAVA 1.6 JRE on ecomstation (former OS/2).
Is it possible to compile the code for JAVA 1.6?

Hi warpwe,

Thanks for your information, I am using gentoo 64-bit version, I cannot run jstock some times with the above error, after compiling java 1.7, everything works.

For others using gentoo 64-bit with the above error, you may try to install icedtea v7 and modify the JAVA_HOME in jstock.sh to execute it

Thanks!

Kenneth
