I would like to install scala 2.8.1. I used exactly all the steps from http://www.scala-lang.org/node/310 but when i write 'scala' in the command prompt then i have the following error 'java' is not recognized as an internal or external command operable program or batch file
Do you know whats going wrong?
As the error message is pointing out, java is missing. You have to install a JRE or JDK and make Scala find it, for example by setting JAVA_HOME to the JRE/JDK.
Have fun with Scala
