I'm a little overwhelmed reading through the ehcache user guide http://ehcache.org/EhcacheUserGuide.html#id.s20. I'm trying to figure out how to set up a simple ehcache app that has a distributed cache. I'd like to just run the app multiple times and have it share the cache between the multiple instances. Is there an example app I can j...
We have an application that uses Hibernate's 2nd level caching to avoid database hits. I was wondering if there is some easy way to invalidate the Java application's Hibernate 2nd level cache when an outside process such as a MySQL administrator directly connected to modify the database (update/insert/delete). We are using EHCache as...
I added the following annotation to enable cache to one of my EJB3 entities, to test caching with ehCache, where I use Hibernate as the persistence provider: .... import org.hibernate.annotations.Cache; import org.hibernate.annotations.CacheConcurrencyStrategy; @Entity @Table(name = "F") @Cache(usage=CacheConcurrencyStrategy.READ_WRITE...
Hi every one, I'm trying to configure seam/ehcache following the tutorial from jboss page: http://docs.jboss.org/seam/2.1.2/reference/en-US/html/cache.html I put the ehcache.1.2.3.jar in project.ear/lib and injected CacheProvider as especified, but the CacheProvider always return null. The documentation doesn't show any aditional conf...
Hi All, I am using EHCache 1.5.0 on a webapp running on WebLogic 9.1 instance and once in a while I run into the following error while getting an element from cache or while checking if an item exists in cache. Has anyone else seen this issue, any suggestions on how to fix this would be great code that causes this issue getMyCache().i...
I want to do something with ehcache in Java that I think should be extremely simple, but I've spent enough time frustrating myself with the docs... Write a value to a disk persistent cache. Shut down. Start up again and read that value. Here is my Java function: private static void testCacheWrite() { // create the cache manager fr...
so, i am really clutching at straws for ideas here. (also note: this is an intermittent problem) i have a 'parent' object with a collection of 'child' objects: <parent stuff> ... <set name="children" inverse="true" order-by="child_id"> <cache usage="read-write"/> <key column="parent_id"/> <on...

Is it possible to have cached queries asynchronous, so that no frontend user actually has to wait for a heavy query to finish? (I.e. heavy query is running as background thread, while (expired) data is delivered from cache. Use case: A web page displaying data, needing some time (too long to wait for when requesting a page) to be collec...

when using ehcache rather than defining statement like <cache name="testonly.package.model.TestPOJOcategory" maxElementsInMemory="200" eternal="true" overflowToDisk="false" timeToIdleSeconds="300" timeToLiveSeconds="600" /> can directly define inside entity independent of whatever cache pro...
This is how my entity look like @Entity @Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) @Table(name = "TestPojoOnly") @NamedQueries({@NamedQuery(name = "TestPojoOnly.findAll", query = "SELECT h FROM TestPojoOnly h"), @NamedQuery(name = "TestPojoOnly.findById", query = "SELECT h FROM TestPojoOnly h WHERE h.id = :id"), @Na...
Hello. This is something of an architecture question. I have this idea of having a server with huge memory, that is used as a big objects cache holder. The clients send "Actions" to this server(like Search Person with property age<13). And then, this machine(to complicate things it would be nice to have more instances of this server and...
if you needed to build a highly scalable web application using java, what framework would you use and why? I'm just reading thinking-in-java, head first servlets and manning's spring framework boo, but really I want to focus on highly scalable architectures etc. would you use tomcat, hibernate, ehcache? (just assume you have to design...
Hello all! I am interested in getting statistics on the Ehcache I have running. I would like to see the number of hits/misses for a given key over a period of time. Perhaps in the form of a map. For example. For the passed hour (or however long it has been running) Key A had 30 hits and 2 misses Key B had 400 hits and 100 misses...
I have an application that uses ehcache for cache (but I think this problem is framework-agnostic), with a method interceptor so basically if I mark my method for caching something like this happnes: public Object invoke(MethodInvocation mi) throws Throwable { Object result = cache.get(key); //key comes from MethodInvoc...
