在weblogic9一个域下部署3个应用,其中一个应用出现错误如下,页面错误为：java.lang 数据下载失败，其他应用正常运行。出错的应用程序启动是没有任何问题的，但运行一段时间后,木有固定时间,程序就会出现该问题,错误部分已经加粗。

错误DAO下类的实现：
public int getCount(Map queryMap) {
??StringBuilder sql = new StringBuilder("SELECT COUNT(1) " + " FROM "
????+ Constant.LOIS_DB_NAME + "LOI_REG t1 " + " LEFT JOIN "
????+ Constant.LM_DB_NAME
????+ "cibaseinfo t2 ON t1.PEYER_ID=t2.custno " + " LEFT JOIN "
????+ Constant.LOIS_DB_NAME + "LOI_LOSS t4 ON t1.LOI_ID=t4.LOI_ID "
????+ " LEFT JOIN " + Constant.LOIS_DB_NAME
????+ "LOI_REQLOG t5 ON t1.APT_SEQ=t5.APT_SEQ " + " LEFT JOIN "
????+ Constant.LOIS_DB_NAME
????+ "LOI_REQLOG t6 ON t1.APT_SEQ=t6.APT_SEQ " + " LEFT JOIN "
????+ Constant.LM_DB_NAME
????+ "cibaseinfo t7 ON t6.PAYEE_ID=t7.custno " + " WHERE 1=1 ");
?
jdk版本为1.5 ，个人觉得问题出现在Constant 常量这个类,但是又不知道 为什么错了，请高手解答，在线急等。。。
?
补充：常量类实现如下：
?// 读取配置文件
?private static final String LOIS_CONFIG = "lois_config.properties";
?//读取数据库名称
?public static String getDBName(String dbName) {
??PropertiesUtil pptUtil = new PropertiesUtil(LOIS_CONFIG);
??String loisDbName = ConverUtil.getObjStr(pptUtil.getValue(dbName)).concat(".");
??System.out.println("读取数据库名称："+loisDbName);
??return loisDbName;
?}
?public static final String LOIS_DB_NAME=Constant.getDBName("LOIS_DB_NAME");//数据库用户
?
常量在加载一次后,在以后的程序运行中,应该是可以直接调用的,搞不明白为什么会出现java.lang.NoClassDefFoundError////
