Windows上でJava実行するバッチを作る

○やりたいこと
libにあるJarファイルを読み込んでJavaを実行したい

■batファイルの作成
@echo off
setlocal EnableDelayedExpansion
for /r %%i in (.\lib\*) do set c=!c!%%i;
java -Xmx1024m -Xms512m -classpath %c% jp.co.example.Main
endlocal

■setlocal
setlocalを使用することにより、設定した環境変数はバッチ内のみ有効となる。

■EnableDelayedExpansion
EnableDelayedExpansionを使用することにより、loop内のsetで値を文字列結合できる。
この場合変数を!で囲む

■Java実行時のメモリ
-Xmx : メモリの最大値
-Xms : 起動時に確保するメモリ値
