Classpath does not work under linux

Category: linux

Tag: , ,

Problem

Anyone know why this command works perfectly in Windows but throws a ClassNotFoundException on Linux? ui. Main

java -cp ".;lib/*" game.ui.Main -Xms64m -Xmx128m

My folder structure is as follows: game/ – Class files lib/ – Jars lib/ – Jars lib/ – Jars lib/ – Jar

Java 6 is the most recent version.

The classpath syntax varies depending on the operating system. According to Wikipedia:

Replace the semi-colon with a colon.

Platform-dependent, the CLASSPATH separator is the same as the character given by java.io.File.pathSeparatorChar.

Windows:

java -cp file.jar;dir/* my.app.ClassName;java -cp file.jar;java -cp file.jar;java -cp file.

Linux:

file.jar:dir/* my.app.ClassName java -cp

Solution #4

When employing classpaths in scripts that are intended to execute on both Windows (i.e. cygwin) and Linux, paths are also significant. When I do this, I include a classpath function like this. With the ‘-w’ option, the ‘cygpath’ tool transforms routes to Windows-style paths. As an example, “/home/user/lib/this.jar” would be transformed to “C:Cygwinhomeuserlibthis.jar” in this case.

#!/bin/bash

function add_java_classpath() {
  local LOCAL1=$1
  if [ "$OSTYPE" == cygwin ]; then
    LOCAL1="$(cygpath -C ANSI -w $LOCAL1)"
  fi
  if [ -z "$JAVA_CLASSPATH" ]; then
    JAVA_CLASSPATH="$LOCAL1"
  elif [ "$OSTYPE" != cygwin ]; then
    JAVA_CLASSPATH="${JAVA_CLASSPATH}:$LOCAL1"
  else
    JAVA_CLASSPATH="${JAVA_CLASSPATH};$LOCAL1"
  fi      
}

add_java_classpath /home/user/lib/this.jar
add_java_classpath /usr/local/lib/that/that.jar

java -cp "${JAVA_CLASSPATH}" package.Main $@
