I'll probably reformat this question in a simpler way.
The goal is to persist an element and retrieve it after restart of a new vm.
so simplifying the test:
private void performSimplerObjectPersistingInMemoryAndDisk(String
> configFile, String expected) throws Exception {
>
> String key = "key", value = "value";
JCS.setConfigFilename(configFile);
> JCS cache = JCS.getInstance("OUR_REGION");
cache.put(key, value);
> Thread.sleep(5000);
> Assert.assertNotNull(cache.get(key));
> Assert.assertEquals(value, cache.get(key));
> System.out.println(cache.getStats());
> CompositeCacheManager.getInstance().shutDown();
> Thread.sleep(5000);
> JCS.setConfigFilename(configFile);
> cache = JCS.getInstance("OUR_REGION");
> Assert.assertEquals(expected, cache.get(key));
> System.out.println(cache.getStats());
> }
...I've been trying this test with a set of configuration files, last one:
# DEFAULT CACHE REGION
> jcs.default=DISK_REGION
> jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
> jcs.default.cacheattributes.MaxObjects=1000

anyone have an idea or example of how this could work?
thanking you in advance
