What's the difference between <%@ include file="header.html" %> and <jsp:include page="header.jsp" />

clock April 9, 2015 21:18 by author Administrator

 

 

1) The include directive: <%@ include file="header.html" %>

Static: adds the content from the value of the file attribute to the current page at translation time. The directive was originally intended for static layout templates, like HTML headers.
2) The <jsp:include> standard action <jsp:include page="header.jsp" />

Dynamic: adds the content from the value of the page attribute to the current page at request time. Was intended more for dynamic content coming from JSPs.
3) The <c:import> JSTL tag: <c:import url=”http://www.example.com/foo/bar.html” />

Dynamic: adds the content from the value of the URL attribute to the current page, at request time. It works a lot like <jsp:include>, but it’s more powerful and flexible: unlike the other two includes, the <c:import> url can be from outside the web Container!

freemarker template engine ------try catch if else loop

clock March 18, 2015 12:58 by author Administrator

 

i think one of best solution for generate code is using template engine like freemarker.
for using try catch or if else and some other expression in it using like this

<#attempt>
attempt block

<#recover>
recover block
</#attempt>



<#if x == 1> x is 1
<#elseif x == 2> x is 2
<#elseif x == 3> x is 3
</#if>


<#list fields as field>
<#list>




this template generate fileds for hibernate hbm.xml

<#list fields as field>
<#attempt>
<#if "${field.type.superclass}"=="class org.model.BaseEntity">
<many-to-one name="${field.name}" column="${field.name}" entity-name="${field.type.name}" not-null="true" />
<#else>
<property column="${field.name}" name="${field.name}" type="${field.type.simpleName}" not-null="false" />
</#if>
<#recover>
<property column="${field.name}" name="${field.name}" type="${field.type.simpleName}" not-null="false" />
</#attempt>
</#list>

jump into interface implementation in Eclipse IDE

clock January 19, 2015 21:22 by author Administrator

here's a big productivity boost if you add an Alt + F3 key binding to the Open Implementation feature,

and just use F3 to go to interfaces, and Alt + F3 to go to implementations.

Open implementation keybinding

 

OR

 

Press Ctrl + T on the method name (rather than F3)
