HELP ME PLEASE!! Trying to make a Simple Struts Portlet to work for 2 years

[Anderson A M Luna, geändert vor 17 Jahren.]

Dears,

I have being trying to develop a Struts Portlet since May 2005 (3.2 version) but I still could not!!

It made me crazy for times, I keep updating versions and Extension Environments but nothing helped!

This is my actual code running on EXT env. Liferay 4.1.2 with Tomcat:

---------------------------------------------------------
liferay-portlet-ext.xml
---------------------------------------------------------

<%@ include file="/html/portlet/ext/usrimc/init.jsp" %>


<title>:: Page Name ::</title>



<br><center> <h3> Page Title </h3> </center>

<form action="<portlet:actionURL windowState=" <%="WindowState.MAXIMIZED.toString()" %>"&gt;<portlet:param name="struts_action" value="/ext/usrimc/actionusrimc" />" method="post" name="<portlet:namespace />fm"&gt;	
	
	
<div align="left">
        
       	<p><font color="#0066FF" face="Verdana"><b>Nome:</b></font> 
	<input name="<portlet:namespace />nome" size="60" type="text" value="">
</p></div>
	<hr color="#99CC66">	   
	
</form>

Hi, sorry you've had trouble, we all have.

I just wanted to make sure that top file wasn't really liferay-portlet.xml, but a jsp file isntead. I'm sure it is, but anyway.

Check out the Struts Portlet presentations at: http://www.liferay.com/web/guest/devzone/presentations

Also the Liferay wiki at: http://wiki.liferay.com/index.php/Developing_Struts_Based_Portlets_on_Liferay_Portal

It looks like you've got a very different method of development than what I use.
You should use the service builder.

Any questions, I'll do what I can.

It seems to be a problem related to the usage of Struts. In fact it looks like a Struts tag does not find an attribute it's looking for. But in the JSP you posted there is no usage of an Struts tag. Isn't there any other JSP code?
