Ajith,
I used the following code to get the value of environment variable
"JAVA_HOME" instead of sysetm variable "java.home" which always points
to jre.
public static String getEnv(String env) throws Exception { //
env="JAVA_HOME"
Properties envVars = new Properties();
Runtime r = Runtime.getRuntime();
Process p = r.exec( "cmd.exe /c set" );
BufferedReader br = new BufferedReader ( new
InputStreamReader( p.getInputStream() ) );
for (String line; (line = br.readLine()) != null; ) {
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
if (key.equals(env))
return line.substring( idx+1 );
}
return "";
}
