Re: Integrate Apache Shiro with Struts2

[tkofford]

I've just uploaded a more advanced example of a struts - shiro application. 

https://github.com/tkofford/shiro-realm
<https://github.com/tkofford/shiro-realm>  

This one is essentially the same as the simple one I created earlier, except
I am using a custom shiro realm and doing authentication & authorization in
the realm instead of relying on the shiro.ini file and the default shiro
behavior. This application can easily be altered to using a database or some
other data store, and is basically how we implement shiro in all our
applications that use shiro.

Please let me know if you have any problems or any questions using the
project.

Portlet Issue From Struts version 2.5 to 2.5.5?

[tkofford]

We've been trying to upgrade from struts 2.5 to struts 2.5.5, and most of our
webapps are portlets. However, with struts 2.5.5 portlets throws the
following exception:

"java.lang.IllegalStateException: Not allowed in a portlet"

Below is the method in the classs
org.apache.struts2.portlet.servlet.PortletServletRequest where this always
happens:

public Cookie[] getCookies() {
if (portletRequest instanceof HttpServletRequest) {
return ((HttpServletRequest) 
portletRequest).getCookies();
}
throw new IllegalStateException("Not allowed in a portlet");
}

Apparently, the "portletRequest" variable is not an instance of
"HttpServletRequest".

That class is invoked by the class
org.apache.struts2.interceptor.I18nInterceptor, which I noticed was changed
from version 2.5 which used the old xwork package version of that class. I
also noticed that cookie handling was added in version 2.5.5.

Finally, below is a partial stack trace. Any help would be greatly
appreciated!

Thanks in advance!

Re: Portlets

[tkofford]

No, I don't remember running into either of those 2 issues, and we have a lot
of struts2 portlets running. However, we mainly only use the view portlet
mode and don't do much with the edit and help portlet modes. The
namespace issue is one that I haven't seen, and we do namespace our
portlets.

Since we develop and run so many portlets, we usually uncover any issues
with upgrades quickly and get right on to submitting fixes for them.

Re: Struts2 Portlets

[tkofford]

Hi Chris,

Almost all of our struts 2 development is to develop portlets, we use the
struts 2 portlet plugin a lot, and it works well for us. We even have a
couple of web applications where we use the same deployed *.war file for a
standalone webapp and a portlet webapp simultaneously.

We deploy our portlets to a pluto portlet container, so we simply add the
following in our pom.xml to have maven include the pluto-specific entries in
the web.xml that included in the resulting *.war file. It's the same build
process for portlet only and portlet + standalone webapp configurations.

From the pom.xml ...


plugin
artifactIdmaven-war-plugin/artifactId
configuration
   
webXml${project.build.directory}/pluto-resources/web.xml/webXml
/configuration
/plugin


plugin
groupIdorg.apache.portals.pluto/groupId
artifactIdmaven-pluto-plugin/artifactId
version${pluto.version}/version
executions
execution
phasegenerate-resources/phase
goals
goalassemble/goal
/goals
/execution
/executions
/plugin

I hope that helps.

JSON Date Format

[tkofford]

I am using the struts2 (v 2.2.3) json-plugin and have a model object field
that is a java.util.Date. However, when this date field is converted to json
data it's coming back like 2011-05-11T09:14:41. Some older browsers (IE7 
IE8) don't like this format, but can handle the milliseconds date format
properly.

Is there any way to specify the format of the date field in my model o9bject
when it is converted to json. NOTE - I'd rather not use annotations, because
my model classes are generated from an XML Schema and I' prefer to not alter
them once generated.

Thanks in advance,
tkoff...@ku.edu
