可以啊 。没问题啊。不是带参数的嘛。
request.setAttribute(“a”，a);
request.setAttribute("b",b);
取的时候。就按照“”里面的值取就可以了

当然可以啊。
像这样request.setAttribute(“a”，a);
request.setAttribute("b",b);

当然可以。request.setAttribute("key","value");
"key"只要不重复就行。

就是用setAttribute();
setAttribute
void setAttribute(String name,Object o)
Stores an attribute in this request. Attributes are reset between requests. This method is most often used in conjunction with RequestDispatcher.
Attribute names should follow the same conventions as package names. Names beginning with java.*, javax.*, and com.sun.*, are reserved for use by Sun Microsystems.
If the object passed in is null, the effect is the same as calling removeAttribute(java.lang.String).
It is warned that when the request is dispatched from the servlet resides in a different web application by RequestDispatcher, the object set by this method may not be correctly retrieved in the caller servlet.

Parameters:name - a String specifying the name of the attributeo - the Object to be stored
以上是标准的API　文档
