Shiro with Wicket
Good morning all.
I'm using Apache Shiro with Wicket. It works perfectly until I attempt to implement EHCache per the instructions. I continue receiving this message upon login:
Last cause: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
The source of the existing CacheManager is: InputStreamConfigurationSource [stream=java.io.ByteArrayInputStream@4db5cb7b]
WicketMessage: Method onFormSubmitted of interface org.apache.wicket.markup.html.form.IFormSubmitListener targeted at [AuthenticationForm [Component id = loginForm]] on component [AuthenticationForm [Component id = loginForm]] threw an exception
Does anyone have any insight into what's causing this? The error suggests that perhaps the Wicket framework is caching the cacheManager bean, but if that's the case I'm unsure of what to do about it.

Ah, that's interesting. I'm not implementing a unique excache.xml, so maybe I should so that I can rename it and test that theory. Thanks for the tip, I'll try that.

Hi Michael,
I'm not using Wicket, but I ran into a similar error with two WAR files in the same Tomcat instance both using EHCache. I had to set a different name for each. One is:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<http://www.w3.org/2001/XMLSchema-instance>
xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true"
monitoring="autodetect" dynamicConfig="true" name="ORMCREST">
The other:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<http://www.w3.org/2001/XMLSchema-instance>
xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true"
monitoring="autodetect" dynamicConfig="true" name="WebTL">
Hope that helps.
