windows - Cygwin and Java

Question

I am new to Cygwin. What are the normal steps that are followed when setting Java classpath and all for running programs in Cygwin?

Answer 1

I'd suggest taking a look at catalina.sh. This shell script launches java under both unix and cygwin environments. Currently, OpenJDK is not part of the Cygwin installer, and people running Java use a Sun build MS executable. This means the paths must be converted to Windows, and when Java is running it will be the same as if it were launched from a batch file.

Specifcally, catalina.sh changes these paths using the cygpath program:

case "`uname`" in
CYGWIN*) cygwin=true;;
esac

if $cygwin; then
  JAVA_HOME=`cygpath --absolute --windows "$JAVA_HOME"`
  JRE_HOME=`cygpath --absolute --windows "$JRE_HOME"`
  CATALINA_HOME=`cygpath --absolute --windows "$CATALINA_HOME"`
  CATALINA_BASE=`cygpath --absolute --windows "$CATALINA_BASE"`
  CATALINA_TMPDIR=`cygpath --absolute --windows "$CATALINA_TMPDIR"`
  CLASSPATH=`cygpath --path --windows "$CLASSPATH"`
  [ -n "$JSSE_HOME" ] && JSSE_HOME=`cygpath --absolute --windows "$JSSE_HOME"`
  JAVA_ENDORSED_DIRS=`cygpath --path --windows "$JAVA_ENDORSED_DIRS"`
