findall()出错！

[钟伟海]

原代码：
try {
Context context = new InitialContext();

Object ref = context.lookup("Supplier");
supplierHome = (SupplierHome) PortableRemoteObject.narrow(ref, SupplierHome.class);

Collection c = supplierHome.findAll();
Iterator iterator = c.iterator();
while(iterator.hasNext()){
Supplier supplier = (Supplier)iterator.next();
System.out.println("the ordersitem's orderid "+ supplier.getShortName());
}

}
catch(Exception e) {
e.printStackTrace();
}

出错信息：

java.lang.ClassCastException: com.inprise.vbroker.rmi.CORBA.ObjectImpl

at supplier.SupplierTestClient1.initialize(SupplierTestClient1.java:40)

at supplier.SupplierTestClient1.<init>(SupplierTestClient1.java:17)

at supplier.SupplierTestClient1.main(SupplierTestClient1.java:112)


但我用findByPrimaryKey(String primaryKey)时没有问题，可以取出值来！
到底哪里出问题了
我是用JB8和BES服务器！

类型转换出错啦

[钟伟海]

类型转换?能否说清楚点！
我调试了，这个出错信息实在Collection c = supplierHome.findAll();这句抛出的，
但是我用System.out.println(c.size());可以显示表中记录数，记录数显示在出错信息的下面！
不明白！

[chenwg168]

Supplier supplier = (Supplier)iterator.next();
Supplier类应该为实体bean的home接口
用这种方法试试：
i=c.size();
while(i>=1)
{
Supplier supplier = (Supplier)iterator.next();
System.out.println("the ordersitem's orderid "+ supplier.getShortName());
i=i-1;
}

哈哈哈，原来高手在这里！！！！

楼上的，麻烦你去看看我的帖子好吗？

是不是也是这个问题？

[钟伟海]

chenwg168(aa) :
我用你的方法，还是同样的错误！！！！

[chenwg168]

更正一下
Supplier类应该为实体bean的远程接口类

[Morgan_ma]

楼主，你的findall返回的是collection么？

[zhousm6]

supplierHome.findAll();
看看你的实体bean里面findAll函数是怎么实现的，返回的collection到底封装了什么类型的类，如果看不懂的话把findAll()这个函数贴出来。

更正：
错误抛出在这句：
Supplier supplier = (Supplier)iterator.next();
System.out.println("ok");

"ok" 不会输出，如果屏蔽掉Supplier supplier = (Supplier)iterator.next();则没有错误提示！！！！

[钟伟海]

我靠，终于是被我解决了，

[Sundery]

说说怎么解决的？
