Struts2 JQuery portlet

[Faramarz Dorani, modificado 11 Anos atrás.]

Hi everyone,

This is my first post on Liferay forum because I'm new to Liferay with great enthusiasm.
I use Struts2 for portlets and also its jquery plugin.

I used this link's example : http://liferay-struts2-portlet.blogspot.com/2012/01/integrate-with-struts2-jquery-plugin.html
I could successfully create a struts2 portlet but when I use <sj:head jqueryui="true"/> in my jsp files it throws an java.lang.IllegalStateException: Not allowed in a portlet.

Point is, when I remove this line: <sj:head jqueryui="true"/> , everything is ok.


I really couldn't solve this.
Could anyone please help me???

More Information to whom would like to reply my post:

Also my portlet.xml file contains:

...
<portlet-class>org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher</portlet-class>
		<init-param>
			<name>view-template</name>
			<value>/view.jsp</value>
		</init-param>
		
		<init-param>
			<name>defaultViewAction</name>
			<value>index</value>
		</init-param>
...

And web.xml :

...
     <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
	
		
	<listener>
		<listener-class>com.liferay.portal.kernel.servlet.SerializableSessionAttributeListener</listener-class>
	</listener>
	<listener>
		<listener-class>com.liferay.portal.kernel.servlet.PortletContextListener</listener-class>
	</listener>
    <listener>
 		<listener-class>com.liferay.portal.kernel.spring.context.PortletContextLoaderListener</listener-class>
	</listener>
	
	<welcome-file-list>
		<welcome-file>/html/view/index.jsp</welcome-file>
	</welcome-file-list>
	
	<servlet>
		<servlet-name>struts2servlet</servlet-name>
		<servlet-class>org.apache.struts2.dispatcher.ng.servlet.StrutsServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>struts2servlet</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>
	<servlet>
		<servlet-name>struts2Resources</servlet-name>
		<servlet-class>org.apache.struts2.dispatcher.ng.servlet.StrutsServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>struts2Resources</servlet-name>
		<url-pattern>/struts/*</url-pattern>
	</servlet-mapping>
...

and index.jsp :

...
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>

<sj:head jqueryui="true" />

<portlet:defineobjects />
<h2>Welcome!</h2>
...

and struts.xml :

...
<action name="index">
	<result>/html/view/index.jsp</result>
...
</action>

My problem is line 5 file index.jsp.

Any suggestion will be appreciated.
tnx.

I have the very same problem. In case you got it solved, I'd appretiate any feedback you can give.

well, the example you pointed to is from my blog.
The problem is caused by struts2-jquery-plugin.

The version you use may be higher then 3.3.3 which I used in my example.
I have noticed that after version 3.5.1, they changed the head.ftl in template.jquery (open the jar file)

The code used to be

<#assign googlePath="http://ajax.googleapis.com/ajax/libs/jquery/${jQueryVersion}">
<#assign googleUiPath="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21">

In the latest version:

<#assign schema="${request.requestURL.substring(0, request.requestURL.indexOf(':'))}">

<#assign googlePath="${schema}://ajax.googleapis.com/ajax/libs/jquery/${jQueryVersion}">
<#assign googleUiPath="${schema}://ajax.googleapis.com/ajax/libs/jqueryui/${jQueryUIVersion}">

request.requestURL doesn't work in Liferay. Reason is that a call to getRequestURL() is not allowed in a portlet (see javadoc for org.apache.struts2.portlet.servlet.PortletServletRequest).

If you don't use SSL in your project, you can fix the problem by delete

<#assign schema="${request.requestURL.substring(0, request.requestURL.indexOf(':'))}">

from head.ftl. And replace ${schema} with http.
Or change it to

<#assign schema="http">

You can post your issue as a comment on my blog, and I will receive an email notification.
