Re: Out of memory being caused by notFoundResources in org.apache.catalina.loader.WebappClassLoader
Chris Yes - ouch indeed ! Yes i'll try them as well - might have a look at the source as well see if there is anything to turn of teh file based validation I had a quick look at the caching and thats totally different sadly. No its definitely the things that are not found. When i get an out of memory the JVM will dump the heap. I've walked it (i know 1 gig...) and its really things that are not found. there are no files by those names so...

I can't see any obvious way to disable the file-based validation configuration. You'd have to ask the struts folks about that.

Out of memory being caused by notFoundResources in org.apache.catalina.loader.WebappClassLoader
Guys Tomcat 6.0.20, java 1.6, linux x64 org.apache.catalina.loader.WebappClassLoader records every resource you asked for that doesn't exist. On our site we have alot of pages ( > 800,000 ) all of which are using struts2 with validation. every hit means the validator does a request for a resource actionName-validation.xml This then gets cached in the WebappClassLoader about line 249 /** * The list of not found resources. */ protected HashMap notFoundResources = new HashMap(); Can this be made into a weak hash map perchance ? or something so that it won't invoke a out of memory. I'm also looking at removing the validator from those urls if anyone knows how to tell the validation interceptor that we don't use the xml files and ONLY use annotations then that would be great :) Ta D
