Hi there! Here's the code: Patient patient = factory.createPatient(); Enhancer enhancer = new Enhancer(); enhancer.setSuperclass(patient.getClass()); enhancer.setCallback(new DefaultMethodInterceptor(patient)); patient = (Patient) enhancer.create(); assertThat(patient.getFirstName()).isNotNull(); ...
Any idea why I am getting this exception? Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myService' defined in class path resource [context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type...
I am using hibernate on the server side with a client application started via Java Web Start. I can't sign the jars (I'd like to but I can't). I get a permission exception when I get a POJO with lazy fields. Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission cglib.debugLocation read) at java...
Hi ! Am trying to create an object using an AOP framework which uses CGLIB to create proxy objects. Strangely enough, the "enhanced" proxy object is devoid of ANY annotations the previous class had! Can anyone tell me how can I make CGLIB retain the annotations on the proxies it creates? Cheers! Nirav ...
I'm noticing terrible speeds when trying to use CGLIB with a callback filter (on tens of thousands of objects) but I'm unable to find any information about optimizing CGLIB. For a search/list interface, the system is loading multiple properties from an optimized query and populating the domain tree with those properties. For all other p...
I use Struts2 and my application has thousands of action classes managed by Spring. I used Spring 2.5.6 before and my application starts quickly. But when I changed Spring to 3.0. I got a extremely slow start up of Tomcat. For each action class, I got the following debug message from Spring: DEBUG (Cglib2AopProxy.java:802) - Unable to a...
Just out of curiosity, are there any (stable) open source projects for runtime java code generation other than cglib? And why should I use them? ...
Is it still possible to force Hibernate 3.3 or 3.5 to use CGLib instead of Javassist? In my properties file, I set hibernate.bytecode.provider = cglib But this doesn't seem to do it. Any thoughts? ...
Hello, I've got a website build with Spring and jpa (by hibernate). I've got a bug and I don't know how to identify the line where the bug appears. I can't debug it on my ide because it's a live version (all runs fine in local). I've got log which says: o rg.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveM...
I lack understanding of how does the generated proxy class object (CGLib enhanced POJO) is transferred to the remote client and still retains its ability to generate Lazy Init. Exceptions. Does that mean that there is some kind of contract that all the transferred objects of some kind of class (a proxy) will be reinstantiated as proxies...
I load additional singleton beans definitions at runtime from external jar file into existing XmlWebApplicationContext of my application: BeanFactory beanFactory = xmlWebApplicationContext.getBeanFactory(); DefaultListableBeanFactory defaultFactory = (DefaultListableBeanFactory)beanFactory; final URL url = new URL("external.jar"); fin...
I'm creating a cli tool to manage an existing application. Both the application and the tests build fine and run fine but despite that I receive a javassist failure when running my cli tool that exists within the jar: INFO: Bytecode provider name : javassist ... INFO: Hibernate EntityManager 3.5.1-Final Exception in thread "main" javax....
Suppose I have an interface with lots of methods that I want to mock for a test, and suppose that I don't need it to do anything, I just need the object under test to have an instance of it. For example, I want to run some performance testing/benchmarking over a certain bit of code and don't want the methods on this interface to contribu...
I have a cglib proxied class because the impl uses both the @Repository @Transactional annotations. I would like to use spring's reflection utils to set the field value for mocking out one of the fields. But when reflection utils can not find the field in my class. How can i get this to work? So then i can mock out the field (collab...
Hi All, Where can we find good Cglib Tutorials online? ...
I see the following example code on how a Java Bean can be created dynamically. What I am not able to figure out is how I can update the state of an instance once created. So in the following example how can I set the value of foo to "footest" for instance bean? BeanGenerator bg = new BeanGenerator(); bg.addProperty("foo", Double.TYPE)...
I know this is very often asked , but I cannot find a working solution : This is my AbstractDAO : public interface AbstractDao<T> { public T get(Serializable id); //other CRUD operations } And this is my JPA's implementation: public abstract class AbstractDaoJpaImpl<T> implements AbstractDao<T> , Serializable { protected Entit...
Hi there, I'm looking for a solution to create an interface in runtime. I don't really know if this is possible in anyway. Problem: I've got a OSGi service which publishes a Map<String,String> where the key defines an action for this service. I want to publish this service directly as Hessianservice with spring but for this, I need to...
Hi, I have a Java library I'm working on that uses cglib to create subclasses of abstract classes provided by the library user, and provides automatically-generated implementations of abstract methods left in there by the user. My problem is that if the method in question has package-local (i.e. default) accessibility, the method I pro...
