The simplest kind of portlet is a JSP portlet that displays text, data, and images, with no interactive capabilities.
For the same purpose, we have to make changes in following 4 files, and create two new JSP file, whose contents are displayed within the portlet (we'll discuss it in end of this post). These 4 files are:
- portlet-ext.xml (/ext/ext-web/docroot/WEB-INF/)
- liferay-portlet-ext.xml (/ext/ext-web/docroot/WEB-INF/)
- liferay-display.xml (/ext/ext-web/docroot/WEB-INF/)
- language-ext.properties (ext/ext-impl/src/content/)
1. portlet-ext.xml
<portlet>
<portlet-name>JSP Portlet</portlet-name>
<display-name>JSP Portlet Introduction</display-name>
<portlet-class>com.liferay.util.bridges.jsp.JSPPortlet</portlet-class>
<init-param>
<name>view-jsp</name>
<value>/html/portlet/ext/jsp_portlet/view.jsp</value>
</init-param>
<expiration-cache>0</expiration-cache>
<supports>
<mime-type>text/html</mime-type>
</supports>
<resource-bundle>com.liferay.portlet.StrutsResourceBundle</resource-bundle>
<security-role-ref>
<role-name>power-user</role-name>
</security-role-ref>
<security-role-ref>
<role-name>user</role-name>
</security-role-ref>
</portlet>
<portlet-name>JSP Portlet</portlet-name>
<display-name>JSP Portlet Introduction</display-name>
<portlet-class>com.liferay.util.bridges.jsp.JSPPortlet</portlet-class>
<init-param>
<name>view-jsp</name>
<value>/html/portlet/ext/jsp_portlet/view.jsp</value>
</init-param>

<resource-bundle>com.liferay.portlet.StrutsResourceBundle</resource-bundle>
<security-role-ref>
<role-name>power-user</role-name>
</security-role-ref>
<security-role-ref>
<role-name>user</role-name>
</security-role-ref>
</portlet>
2. liferay-portlet-ext.xml
<portlet>
<portlet-name>JSP_Portlet</portlet-name>
</portlet>
<portlet-name>JSP_Portlet</portlet-name>
</portlet>
3. liferay-display.xml
<category name="newcategory.category1">
<portlet id="MyJSPPortlet" />
</category>
<portlet id="MyJSPPortlet" />
</category>
4. language-ext.properties
javax.portlet.title.Sample=JSP Portlet
newcategory.category1=NewCategory
newcategory.category1=NewCategory
The two files that we need to make, are init.jsp and view.jsp. init.jsp plays a big role in whole portlet lifecycle (here I am giving just an overview of this file, will write a dedicated post on it) and view.jsp is a file which is the page to be displayed within the portlet.
- init.jsp (ext/ext-web/docroot/html/..)
- view.jsp (ext/ext-web/docroot/html/..)
1. init.jsp
<%@include file="/html/portlet/init.jsp"%>
2. view.jsp
Write some JSP page here (I hope you can do that :) )
then deploy and Enjoy...
