A simple query for a cache which contains User classes will fail for queries with the error below.

UserData class for the cache:
public class Test implements Serializable {
private int testId;
public Test(){}
public Test(int myId)

{this.testId = myId;}

public int getTestId()

{return animalId;}

public void setTestId(int testId)

{ this.testId = testId;}

}

Simple EJB for test
@Singleton
@Startup
public class TestInfinispanQuery4EAPConfig {
@Resource(lookup = "java:jboss/datagrid-infinispan/container/jdg-container/cache/EAPcache")
private Cache<String, Object> cache;

@PostConstruct
public void LoadDBToMemory()

{ cache.put("1", new Test(2, 0)); cache.put("2", new Test(2, 0)); cache.put("3", new Test(1, 0)); QueryFactory queryFactory = Search.getQueryFactory(cache); Query q = queryFactory.from(Test.class).having("testId").eq(2).build(); int size = q.getResultSize(); System.out.println("result = " + size); }

}
