在Eclipse中編寫Java代碼時，用到了BASE64Decoder，import sun.misc.BASE64Decoder;可是Eclipse提示：
Access restriction : The type BASE64Decoder is not accessible due to restriction on required library C:\Program
files\java\jre6\lib\rt.jar
Access restriction : The constructor BASE64Decoder() is not accessible due to restriction on required library C:\Program files\java\jre6\lib\rt.jar
搞不懂是為什么，最后在http://forums.dzone.com/eclipse/384-access-restriction- problems.html找到答案，只需要在project build path中先移除JRE System Library，再添加庫JRE System Library，重新編譯后就一切正常了。但是我仍然很疑惑是為什么。。。

Criteria for selecting only a matching set of records from a DataSource. Criteria can be applied on the client and server. Unless configured otherwise, criteria will generally be applied client-side by ResultSets via ResultSet.applyFilter().

Client- and server-side systems built into SmartClient understand two criteria formats by default: simple key-value pairs (Criteria) or the AdvancedCriteria format.

Simple key-value Criteria are represented via a JavaScript Object where each property specifies the name and required value for a field. Multiple legal values for a field can be provided as an Array. For example:

 var criteria = {     field1 : "value1",     field2 : ["value2", "value3"]  }  

Would select all records where field1 has value "value1" and where field2 has either "value2" or "value3". When writing custom client and server-side filtering logic, criteria must be a JavaScript Object but the properties of that Object can contain whatever data you want. When
 sent to the SmartClient server, the Java representation of the criteria is described here. When sent to other servers, the operationBinding.dataProtocol affects the format.

AdvancedCriteria is a format for representing search criteria which may include operators on field values such as "less than", or may include sub-clauses such as several criteria applied to fields joined by an "OR" operator.

SmartClient DataSources can use AdvancedCriteria to search a list of Records, and the SmartClient Java Server can translate AdvancedCriteria to either SQL or Hibernate queries (Note: The server-side AdvancedCriteria handling feature is only available with the Power and Enterprise Editions of SmartClient; the Pro Edition is limited to ordinary criteria handling on the server side).可惜Power版和Enterprise版都老貴老貴的，企業版的都有按CPU賣的了，暈倒。

If the entire dataset is cached locally, SmartClient can perform AdvancedCriteria filtering on the client, avoiding a server call.

An AdvancedCriteria is an ordinary JavaScript object which can be created directly with JavaScript literal notation. For example:

var advancedCriteria = {
        _constructor:"AdvancedCriteria",
        operator:"and",
        criteria:[
            // this is a Criterion
            { fieldName:"salary", operator:"lessThan", value:"80000" },
            { operator:"or", criteria:[
                  { fieldName:"title", operator:"iContains", value:"Manager" },
                  { fieldName:"reports", operator:"notNull" }
              ]  
            }
        ]
    }

An AdvancedCriteria is in effect a Criterion that has been marked with _constructor:"AdvancedCriteria" to mark it as complete criteria.
