无法通过bat文件运行Java

Question

I set my environment variables correct, and while running Java <classname> it is running fine.

But when running the same through a bat file, I'm getting errors like java is not recognized as internal or external command or bat file .

I tried displaying the path and classpath, but everything is fine there. What am I doing wrong?

Here is my piece of code:

cd\
cd C:\myproject
set PATH="C:\Program Files\Java\jdk1.7.0_51\bin;"%PATH%
set CLASSPATH="C:\myproject\sqljdbc4.jar;C:\myproject\jxl-2.6.12.jar"
java InsertRecords %1 %2
pause

Answer 1

java executable isn't covered in PATH, add it to path

change it to

set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_51\bin\

Answer 2

I think the problem is with how you are setting the path variable...take a look at this...

"C:\Program Files\Java\jdk1.7.0_51\bin;"
                                      ^---This doesn't look right

Try using something more like...

set PATH="C:\Program Files\Java\jdk1.7.0_51\bin";%PATH%
                                               ^--- Note the change here...

Answer 3

PATH变量中的长路径名中不需要引号。
