Trying to use Spring in Portlet - SEVERE: Error listenerStart

[Sarah Killcoyne, modificado 16 Anos atrás.]

I'm new to spring and I've played with portlets only a little. I managed to get a basic portlet running in liferay (after pulling ever lib out of the war that liferay already has) however, now I'm trying to get a spring based portlet running and it always fails to startup:

The only error I ever see is "SEVERE: Error listenerStart". I've pulled all the libs out that I could see that also appear in the liferay lib directory and I've tryied commenting out various things in the xml files and I always get this error (which is completely useless and might have me going in the wrong direction entirely). Googling this error obviously doesn't get me very far.

Any suggestions??

I'm really surprised no one else has come across this. I got help from one of our guys who used liferay a some a year ago and he was stumped too. I'll be trying this in other portals so maybe it will become more clear.

It happened to me 10 minutes ago with the mail portlet and i'm lost. Have you fix it?

Hi Sarah,

It would be very helpful if you had proper project settings in Spring MVC.

Here is real example (posted on 1/9/08) in Plugins SDK

Good Luck!

I had the exact same problem and after much research/trial and error I discovered an issue with the context load listener when deploying multiple portlets. Every portlet must have a unique webAppRootKey configured in web.xml or you will get this error on startup: java.lang.IllegalStateException: Root context attribute is not of type WebApplication . I thought it was a classpath problem, but this turned out to solve the problem for me.

Please add the following to web.xml to fix this problem.

<context-param>
<param-name>webAppRootKey</param-name>
<param-value>MyPortlet</param-value>
</context-param>

This is a complete web.xml sample:
