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>
.....
