xml等配置文件行首的编码(<?xml version="1.0" encoding="gb2312"?>)不能去除，会导致xml解析错误.

启动脚本加上-Xbootclasspath即可使用循环获取jar：

for jar in ${WORK_HOME}/lib/*.jar; do
LIBPATH="$LIBPATH:$jar"
done
CLASS_PATH=${WORK_HOME}/config:$LIBPATH

nohup java -Dtarget=$PNAME -Duser.home=$USER_HOME -Xbootclasspath/p:${LIB}/xercesImpl.jar:${LIB}/xercesSamples.jar :${LIB}/xmlParserAPIs.jar -cp ${CLASS_PATH} XXXMain >> ${WORK_HOME}/log/main.log`date +%m%d` 2>&1 &
