GWAN无法识别Sun Java 7

Question

OS: Ubuntu 12.04 Desktop

Java installed: java version "1.7.0_05" Java(TM) SE Runtime Environment (build 1.7.0_05-b05) Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

Running sudo ./gwan gives following error:- Please install OpenJDK or SUN Java .

'report.java': to use Java (*.java) scripts, install 'javac' (sudo apt-get install javac).

'loan.java': to use Java (*.java) scripts, install 'javac' (sudo apt-get install javac).

'argv.java': to use Java (*.java) scripts, install 'javac' (sudo apt-get install javac)..

'hello.mm': to use Objective-C++ (*.mm) scripts, install 'gobjc++' (sudo apt-get install gobjc++)

'all.java': to use Java (*.java) scripts, install 'javac' (sudo apt-get install javac)

Javac, Java both in sys path, both available in terminal

I have not touched any configuration files just went through http://gwan.com/download then tried heading over to

localhost:8080/?hello.java

note: all C files work.

Have not tried openJDK though I would like to stay away from this option.

Answer 1

Try to use the JAVA_HOME environment variable to tell which JVM should be used. The G-WAN site has a dedicated Java FAQs entry for that question.

Reporting the same kind of problems in the past I have been told that the next release will be more JVM-agnostic.
