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 &
