救救我吧！JSP循环取Oracle数据的问题

Question

作一个统计功能的时候遇到的问题。我通过循环取出数据，在同一个循环开始的一些存取中数据是正常的，但是到后面还剩两次循环的时候写SQL语句的字符串就被截断了，，
程序和报错如下：
{
  String strSqlTJ="select continent,count(WEB_LOG_DLSJ) as CS  from WEB_LOG  left join Continent on WEB_LOG.WEB_LOG_ADDJ  like '%'||Continent.Country||'%' where WEB_LOG.WEB_LOG_URL like '"+sURL+"%' and WEB_LOG_DLSJ between To_Date('"+strStart+"','YYYY-MM-DD') and To_Date('"+strEnd+"','YYYY-MM-DD') group by continent"; 
   out.print(strSqlTJ); ////这里出问题字符串截断。
 dbRst = stmt.executeQuery(strSqlTJ);
  while(dbRst.next())
{       
iCount++;
List ARow = new ArrayList();
ARow.add(dbRst.getString("continent"));//区域
ARow.add(dbRst.getString("CS"));//次数   
LArea.add(ARow);
}
dbRst.close();
dbRst = null;

}
最后几个循环的SQL输出
select continent,count(WEB_LOG_DLSJ) as CS from WEB_LOG left join Continent on WEB_LOG.WEB_LOG_ADDJ like '%'||Continent.Country||'%' where WEB_LOG.WEB_LOG_URL like '/keling/page/power/guangfu%' and WEB_LOG_DLSJ between To_Date('2005-1-1','YYYY-MM-DD') and To_Date('2006-1-1','YYYY-MM-DD') group by continentselect continent,count(WEB_LOG_DLSJ) as CS from WEB_LOG left join Continent on WEB_LOG.WEB_LOG_ADDJ like '%'||Continent.Country||'%' where WEB_LOG.WEB_LOG_URL like '/keling/page/power/igbt%' and WEB_LOG_DLSJ between To_Date('2005-1-1','YYYY-MM-DD') and To_Date('2006-1-1','YYYY-MM-DD') group by continentselect continent,count(WEB_LOG_DLSJ) as CS from WEB_LOG left join Continent on WEB_LOG.WEB_LOG_ADDJ like '%'||Continent.Country||'%' where
