我有3个使用netbean 6.9创建的Web服务

当我在工作中使用计算机时,它运行顺畅,没有错误.但是,当我将netbean项目复制到我家的计算机时,它运行时出现错误,如下所示.

我正在使用oracle和hibernate进行映射.我想用count()函数中的条件计数.我的代码是:

选择计数(st.averageMark <su.gradePass然后1其他0结束时的情况)来自Study st join st.subject su,其中st.acaYear在(2009)和st.semester = 4,su.idSeq = 1330 group by st. acaYear

代码没有回报我.我使用sum而不是count它返回了一个结果,但它是错误的,结果比我想象的要大.

预先感谢.

我正处于开发基于Java的Web应用程序的开始阶段.我可以同样使用Strut,Grail和Play.您能否指出哪些框架最适合长期开发Web应用程序,或者只使用普通的MVC(M-java bean,V-jsp,jstl,C-servlet)？

请在这件事上给予我帮助

我正在创建一个组件.我的组件中有一个config.xml我在userCheck.php中编写自定义JFormFieldUserCheck我想从config.xml加载参数或字段

我用了

$param = JComponentHelper::getParams('com_my-component');
var_dump($param);

Resul是

object(stdClass)#214 (0) { }

但是当我将com_my-component更改为com_content(Joomla默认组件)时.然后var_dump,结果很好.

提前致谢
