Dear Sirs:

I am very sorry, I am a beginner and need some help, I just read the book "Java 2 Micro Edition" and try to use the example code in the book, when I compiled the example code in the chapter 5 (in this code it will use the String class and its operator "+"), the compilation result will show some error message to indicate that it can not find the StringBuilder.class in the directory javalang and not know the operator "+", what is wrong, please give me some hint how to install the xxxBuilder into the javalang, I'll appreciate very much!

My development environment is built by J2SE 5.0 and MIDP 2.0, thanks a lot!

Sincerely yours,
