[12:48:35 EST(-0500)] <philosophia> hi - i was able to deploy a new portlet and publish it without any errors. but when i try to add it to my layout i get 'PlutoInvoker not available' errors - http://uportal.pastebin.com/md46260e
[12:49:18 EST(-0500)] <philosophia> this actually happened with two portlets. anyone know what this error means?
[12:59:52 EST(-0500)] <holdorph> that tends to be a mismatch between the information entered in the channel manager interface and what is the reality underneath
[13:00:07 EST(-0500)] <holdorph> it's especially common to mis enter the web app name or portlet name
[13:00:42 EST(-0500)] <holdorph> so, in your pastebin case, what is the 'webapp' as tomcat knows it to be? Look inside the tomcat webapps directory
[13:01:06 EST(-0500)] <holdorph> remember also it's case sensitive, so the case of the directory name is important
[13:01:33 EST(-0500)] <holdorph> the other piece you have to verify is what is the contents of the <portlet-name> element in the portlet.xml
[13:01:42 EST(-0500)] <philosophia> yeah it's 'Hello' in tomcat /webapps
[13:01:48 EST(-0500)] <holdorph> compare those two things to what you entered in channel manager.
[13:01:52 EST(-0500)] <philosophia> but i think i named the portlet 'Hello World'
[13:04:28 EST(-0500)] <philosophia> do you 'undeploy' a portlet by blowing away it's directory under tomcat /webapps?
[13:07:27 EST(-0500)] <holdorph> it's really multiple steps, but if you dismiss the uportal interface/datbase pieces, then yes, just deleting the directory is enough
[13:08:08 EST(-0500)] <holdorph> but if you had already published it and it was in use in different layouts, it's more complicated. unless you're just trying to reinstall/redeploy with a new version.

[13:36:31 EST(-0500)] <philosophia> i tried re-deploying, and still get the error. the channel name i'm using in channel manager is 'Bookmark Portlet' but the portlet is deployed as <tomcat home>/webapps/WebUtils
[13:36:44 EST(-0500)] <philosophia> should i change the channel name to 'WebUtils'?
[13:45:11 EST(-0500)] <philosophia> i also notice - portlet.xml looks like <portlet-name>BookmarkPortlet</portlet-name>
[13:45:11 EST(-0500)] <philosophia> <display-name>Bookmark Portlet</display-name>
[13:45:34 EST(-0500)] <philosophia> i changed portlet name in channel manager to 'BookmarkPortlet' (without the space) but i still get the error
[13:45:39 EST(-0500)] <EricDalquist> so when you publish a portlet there are two values that you need to have exactly right
[13:45:53 EST(-0500)] <EricDalquist> they are the portlet application name which in your case would be /WebUtils
[13:46:04 EST(-0500)] <EricDalquist> and the portlet name which in your case would be BookmarkPortlet
[13:46:12 EST(-0500)] <EricDalquist> that is configured on the second screen of the workflow
[13:46:25 EST(-0500)] <EricDalquist> the actual name/title of the portlet as your publishing it in uPortal doesn't matter
[13:47:58 EST(-0500)] <philosophia> ah i got it going
[13:48:17 EST(-0500)] <philosophia> after changing portlet name to 'BookmarkPortlet' then re-publishing it, it works
[13:48:45 EST(-0500)] <philosophia> only thing i notice is - it now shows up twice under add content>applications
[13:49:08 EST(-0500)] <philosophia> thanks
[13:50:18 EST(-0500)] <philosophia> i must've published it twice, i removed it from channel manager and now it only shows up once under add content

[15:09:44 EST(-0500)] <holdorph> EricDalquist did you notice ehcache 1.7.1 came out and now uses SLF4j ?
[15:09:51 EST(-0500)] <EricDalquist> yup
[15:10:06 EST(-0500)] <EricDalquist> I did a bit of the patching work for them
[15:10:24 EST(-0500)] <EricDalquist> since I had to get a local mod of ehcache using slf4j here to debug distributed caching issues
