Description
JSP Packages - The JSP API( Application programming Interface) has three packages.
- javax.servlet.jsp--->Core JSP 2.0 API.
- javax.servlet.jsp.el--->JSP 2.0 Expression Language API.
- javax.servlet.jsp.tagext--->Definition for JSP Tag libraries.
Description
| Interface | Description |
|---|---|
| HttpJspPage | Depicts the correspondence that a JSP Page Implementation Class must satisfy while using the HTTP convention. |
| JspPage | Delineates the non particular affiliation that a JSP Page Implementation class must satisfy; the pages that usage the HTTP convention is depicted by the HttpJspPage interface. |
| Classes | Description |
|---|---|
| JspContext | It goes about as base class for the PageContext class and processes all information that is not specific to servlets. |
| ErrorData | It will have the information about the mistake pages. |
| JspEngineInfo | It is an abstract class and underpins information on the current JSP page. |
| JspFactory | Represents the factory methods that were present to the dynamic time of JSP to create the object to the classes and interfaces that supports to the JSP implementation. |
| JspWriter | Template data will be written by JspWritter in JSP page. |
| PageContext | It extends JspContext and used when JSP works on Servlet Environment. |
| Exceptions | Description |
|---|---|
| JspException | JspExceptions will bring about a conjuring of the errorpage hardware. |
| JspTagException | Exception to be utilized by a Tag Handler to demonstrate some unrecoverable screw up. |
| SkipPageException | To show the calling page must stop appraisal. |
Description
| Interface | Description |
|---|---|
| FunctionMapper | To map between EL functions and methods. |
| VariableResolver | To re-try the way an ExpressionEvaluator decides variable references at evaluation time. |
| Classes | Description |
|---|---|
| Expression | For a readied expression. |
| ExpressionEvaluator | To evaluate the expression language. |
| Exception | Description |
|---|---|
| ELException | Indicates the conditions of an exception while evaluation. |
| ELParseException | Indicates the parsing error while parsing. |
Description
| Interfaces | Description |
|---|---|
| BodyTag | amplifies IterationTag by characterizing extra methods that give a tag handler a chance to control the substance of assessing its body. |
| DynamicAttributes | It accepts dynamic attributes. |
| IterationTag | augments Tag by characterizing one extra methods that controls the reconsideration of its body. |
| JspTag | Represents the factory methods that were present to the dynamic time of JSP to create the object to the classes and interfaces that supports to the JSP implementation. |
| SimpleTag | To define tag handlers. |
| Tag | Tag handler will not have any longing to control its body. |
| TryCatchFinally | It is spare tag that needs extra snares for overseeing assets. |
| Classes | Description |
|---|---|
| TagInfo | This class is begun from the TLD and is available exactly at interpretation time. |
| BodyTagSupport | Characterizing tag handlers actualizing BodyTag. |
| FunctionInfo | Data for a function . |
| JspFragment | Exemplifies a segment of JSP code in an instance that can be conjured the same number of times as required. |
| PageData | Fetching time data on page. |
| SimpleTagSupport | Defines tag handler that implements simple tag. |
| TagAdapter | It can wrap the simple tag, exposes it by tag interface. |
| TagAttributeInfo | Data of the attributes available at translation time. |
| TagData | Gives value for a tag instance. |
| TagExtraInfo | Tag library provide extrs class to indicate extra interpretation time data not depicted in the TLD. |
| TagFileInfo | This class is begun from the TLD and is open exactly at translation time. |
| BodyContent | An encapsulation of the appraisal of the body of a movement so it is open to a tag handler. |
| TagLibraryInfo | Translation time information associated with a taglib catalog, and its concealed TLD record. |
| TagLibraryValidator | This class is about translation time validator. |
| TagSupport | Defines new tag handlers. |
| TagVariableInfo | This class is begun from the TLD and is available exactly at translation time and gives variable data of the tag. |
| ValidationMessage | This class from either TagExtraInfo or TagLibraryValidator. |
| VariableInfo | Works on scripting variables. |
Key Points
- JSP Packages - Developer should import the required packages to provide classes and interfaces .
- JSP Packages - While working with IDE, JSP Packages needs to be import before the compiling.
