What are the standard attributes that should be passed to a custom tag in a JSP page?
Consider including the following properties for an attribute −
| S.No. | Property & Purpose |
|---|---|
| 1 | name The name element defines the name of an attribute. Each attribute name must be unique for a particular tag. |
| 2 | required This specifies if this attribute is required or is an optional one. It would be false for optional. |
| 3 | rtexprvalue Declares if a runtime expression value for a tag attribute is valid |
| 4 | type Defines the Java class-type of this attribute. By default, it is assumed as String |
| 5 | description Informational description can be provided. |
| 6 | fragment Declares if this attribute value should be treated as a JspFragment. |
Following is the example to specify properties related to an attribute −
..... <attribute> <name>attribute_name</name> <required>false</required> <type>java.util.Date</type> <fragment>false</fragment> </attribute> .....
If you are using two attributes, then you can modify your TLD as follows −
..... <attribute> <name>attribute_name1</name> <required>false</required> <type>java.util.Boolean</type> <fragment>false</fragment> </attribute> <attribute> <name>attribute_name2</name> <required>true</required> <type>java.util.Date</type> </attribute> .....
