exception when i deploy the application. Not sure how long this thing will take to
resolve.. or what's the other options??

Hello,
I'm have the same problem with Spring MVC Annotations.
Here me applicationContext:
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<context:component-scan base-package="de.example.web.servlet" />
Here the Spring MVC Servlet with Annotations
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
@Controller
@RequestMapping("/index")
public class Home {
@RequestMapping(method = RequestMethod.GET)
public ModelAndView index(HttpServletRequest request) {
ModelAndView mav = new ModelAndView("index");
mav.addObject("test", "Hello World!");
return mav;
}
}

Hi,
I just ported an existing Spring (2.5.6) Web MVC/JPA app to Google App Engine, but it took me a couple of hours to get it running. At the end, I was confronted with two things causing Security exceptions when running
the app on GAE:
1) Using something somewhere in Spring JPA
2) Using Spring form tags (if anybody wants a fix for this one, let me know)
The following source and bean config got rid my "...'org.springframework.context.annotation.internalPersistenceAnnotationProcessor': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError:
javax/naming/NamingException..."
Java source:
package com.bsdroot.todo.web.gae.fixes;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* GAE: Spring JPA: Needed to get around the "java.lang.NoClassDefFoundError:
* javax/naming/NamingException" blacklisting problem.
*
* Just register this dummy impl as bean with id: org.springframework.context.annotation.internalPersistenceAnnotationProcessor
*

public class GaeFixInternalPersistenceAnnotationProcessor {
private static final Logger log = LoggerFactory
.getLogger(GaeFixInternalPersistenceAnnotationProcessor.class);
public GaeFixInternalPersistenceAnnotationProcessor() {
log
.info("Creating fake internalPersistenceAnnotationProcessor to bypass GAE blacklist problem");
}
}

Many thanks, this fix worked for me.

for some reason it worked for me after i added few jars like annotation-api.jar

I'm using absolutely no persistence at all. That's right. No jpa. No jdo. Nothing.
Just a simple spring mvc (2.5.6) app with a single controller that spits out hello
world, and guess what? Exactly. Don't believe me? Try it!
This issue is misnamed, and the finger shouldn't be pointed at JPA.

This bug applies to Spring 2.5.x, Spring 3.0.0.x seems to work.
One workaround for Spring 2.5.x si to use modified
org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor
and org.springframework.jndi.JndiLocatorSupport with
javax.naming.NamingException replacetd to java.lang.Exception

You don't have to remove spring-orm.jar to fix the issue, but you cannot use a proxy factory for transactions. I removed this line and it worked.

<property name="targetPersistenceManagerFactory" ref="persistenceManagerFactory" />

this is is sure in spring2.5.6,
now i update my GAE ,use spring3.0.5,is worked!

I have found a fix for this problem for Spring 3.0.5 + JDO. The problem was again java.lang.ClassNotFoundException: javax.naming.NamingException.
Proper wiring of persistence manager + proxy + transaction manager is as follows:
<bean id="persistenceManagerFactory" class="org.springframework.orm.jdo.LocalPersistenceManagerFactoryBean">
<property name="persistenceManagerFactoryName" value="transactions-optional" />
</bean>
<bean id="persistenceManagerFactoryProxy" class="org.springframework.orm.jdo.TransactionAwarePersistenceManagerFactoryProxy">
<property name="targetPersistenceManagerFactory" ref="persistenceManagerFactory" />
<property name="allowCreate" value="false" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jdo.JdoTransactionManager">
<property name="persistenceManagerFactory" ref="persistenceManagerFactory" />
</bean>
I have found that during instantiation of org.springframework.orm.jdo.TransactionAwarePersistenceManagerFactoryProxy in setter setTargetPersistenceManagerFactory() spring tries to instantiate a class org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory (which is a mystery for me...). However this class implements 3 interfaces:
1. javax.jdo.PersistenceManagerFactory
2. javax.naming.spi.ObjectFactory
3. javax.naming.Referenceable
Nevertheless the last two interface are not permitted by appengine runtime. Therefore I reduce the implemented interfaces to contain just the first one. The fix looks as follows (patch org.springframework.orm.jdo.TransactionAwarePersistenceManagerFactoryProxy)
/**
* Set the target JDO PersistenceManagerFactory that this proxy should
* delegate to. This should be the raw PersistenceManagerFactory, as
* accessed by JdoTransactionManager.
* @see org.springframework.orm.jdo.JdoTransactionManager
*/
public void setTargetPersistenceManagerFactory(PersistenceManagerFactory target) {
Assert.notNull(target, "Target PersistenceManagerFactory must not be null");
this.target = target;
// hack: javax.naming.* classes not permitted by app-engine
// iface[0]: javax.jdo.PersistenceManagerFactory
// iface[1]: javax.naming.spi.ObjectFactory
// iface[2]: javax.naming.Referenceable
// keep just iface[0]
Class[] ifcs = ClassUtils.getAllInterfacesForClass(target.getClass(), target.getClass().getClassLoader());
Class[] _ifcs = new Class[] { ifcs[0] };
// we MUST NOT touch ifcs[1] nor ifcs[2] - they are javax.naming
this.proxy = (PersistenceManagerFactory) Proxy.newProxyInstance(
target.getClass().getClassLoader(), _ifcs, new PersistenceManagerFactoryInvocationHandler());
}

Building on solution #23, I opted to fix it by extending TransactionAwarePersistenceManagerFactoryProxy with my own class, where I've overridden the default behaviour. This works well if you don't have the option of patching and rolling your own Spring.
Code then looks like this:
package org.springframework.orm.jdo;
import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Proxy;
import javax.jdo.PersistenceManagerFactory;
import org.springframework.util.ClassUtils;
public class GAETransactionAwarePersistenceManagerFactoryProxy extends TransactionAwarePersistenceManagerFactoryProxy {
@Override
public void setTargetPersistenceManagerFactory(PersistenceManagerFactory target) {
try {
// Set the "target" field. Which is private. So we need some dirty reflection.
Field targetField = TransactionAwarePersistenceManagerFactoryProxy.class.getDeclaredField("target");
targetField.setAccessible(true);
targetField.set(this, target);
// hack: javax.naming.* classes not permitted by app-engine
// iface[0]: javax.jdo.PersistenceManagerFactory
// iface[1]: javax.naming.spi.ObjectFactory
// iface[2]: javax.naming.Referenceable
// keep just iface[0]
Class<?>[] ifcs = ClassUtils.getAllInterfacesForClass(target.getClass(), target.getClass().getClassLoader());
Class<?>[] _ifcs = new Class[] { ifcs[0] };
// Reflection needed since PersistenceManagerFactoryInvocationHandler is a private inner
// class.
@SuppressWarnings("unchecked")
Class<? extends InvocationHandler> clazz = (Class<? extends InvocationHandler>) getClass().getClassLoader().loadClass("org.springframework.orm.jdo.TransactionAwarePersistenceManagerFactoryProxy$PersistenceManagerFactoryInvocationHandler");
Constructor<? extends InvocationHandler> constructor = clazz.getDeclaredConstructor(TransactionAwarePersistenceManagerFactoryProxy.class);
constructor.setAccessible(true);
InvocationHandler invocationHandler = constructor.newInstance(this);
PersistenceManagerFactory proxy = (PersistenceManagerFactory) Proxy.newProxyInstance(target.getClass().getClassLoader(), _ifcs, invocationHandler);
// Set the "proxy" field. Which is private. So we need some dirty reflection.
Field proxyField = TransactionAwarePersistenceManagerFactoryProxy.class.getDeclaredField("proxy");
proxyField.setAccessible(true);
proxyField.set(this, proxy);
} catch (Exception e) {
throw new RuntimeException("Error when trying to workaround issue with GAE and Spring 3.1. You might get this if you've upgraded Spring (since the reflection being done makes a lot of assumptions about the inner workings of Spring JDO).", e);
}
}
}
