It would still be nice to get all or most of the tests working in Eclipse again, but it'll have to wait a while. In the meantime, it's reasonable to run tests individually in Eclispe while writing code, and then run everything from ant right before checking in to make sure nothing's broken.

Colin, This is excellent. It seems like I can run the tests faster than I can type this email :-) The failing JUnit tests within Eclipse were starting to bother me and testing with Ant was too slow. Now the Ant tests take only 10% extra compared to running within Eclipse. Definitely worth the upgrade!!!! Thanks for figuring this out.

I spent a bit more time and got this going. Running the "tests" target from command-line went down for me from about 6:40 to 1:37. Note bad! To get things going, I set the <junit> element forkmode to 'perBatch'. Then I excluded the 3 tests from the main <batchtest> element, and added them as 3 separate single test <batchtests> (still kept as <batchtest> instead of <test> so the default excludes would still work. It's not that great to have to name tests individually like this, but it's just a few. If this has to be done for a few more, it will actually get less verbose to just use a separate junit task instance, then one instance would have forkMode="perBatch", and one forkMode="perTest" (the default).

Hello, I am using Spring 1.0.2 and using the XSLTViewResolver. I know there was a problem getting the include directive in the stylesheet to work (e.g. include="includedfile.xslt") so that the path can be relative to the WEB-INF rather than your system home directory (e.g. file:///c:\................). Can anyone provide the solution to this. I have to use the latter way right now and it is obviously not preferred since moving the app to different environments or having different developers working with the stylesheet requires this path update in the 'include' directive. Thank you. |

Claudio, I'm not completely sure to understand correctly your question, but I will try to answer as best as I can. WeakHashMap is implemented with WeakReference for keys, and strong reference for values. That means if the value has a strong reference on the key, then the key cannot be garbage collected until the WeakHashMap is ready for collection. However, if the value has no strong reference on its key, then being in the WeakHashMap won't prevent the key and value from being garbage collected if it is otherwise ready. The WeakHashMap knows when to remove the key (and the value with it) by using the notification provided by the java.lang.ref package. For more information on this, see: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/ref/package-summary.html So the problem here with the CachedIntrospectionResults is that it uses BeanInfo and PropertyDescriptor that both have strong reference to the class (indirectly by a reference on Methods of the class). That will be solved with JDK 1.5 that uses a combinaison of Weak and Soft Reference to the Class and Method objects, but for 1.4.2, there's not really any better solution than to flush the Introspector's cache and/or use WeakReference on CachedIntrospectionResults. Using WeakReference on the CachedIntrospectionResults is safer, but decrease performance, and in such case a manual Instrospector.flushFromCaches(Class) must be used, so that the Instrospector does not keep a strong reference on the BeanInfo. When a webapp is hot-redeployed, a new ClassLoader is created to load the webapp, and the old one is thrown away, expected to be garbage collected. For the collection to happen, the server must clear any strong reference to the ClassLoader or its classes, and also the webapp must make sure that any code in parent ClassLoaders (or siblings) clear any reference it might have to any of the webapp's class. Hopefully this answers your question, but if it does not (or if it's not clear enough), please give me more details of what information you need.

Ant 1.6.2 is out, and with it support for a forkmode="once" on the junit
task, which allows ant to still fork for junit tests, but only once for
the entire task (instead of for each testcase). Alternately,
forkmode="perBatch" allows forking once per batch element.
This is pretty promising, since it could bring the time to run the test
suite from ant down to a similar value to when running in an IDE, which
is currently much faster.
I've tried to give it a go (making sure to remove the ant 1.6.1 in the
lib dir, otherwise that will interfere), by adding forkmode="once" to
the junit element in the tests target. It is currently breaking on
SqlStateExceptionTranslatorTests, due to the initial context factory
builder already being set. This should be resolvable by using a separate
batch for that test, or some other strategy. I am curious however why
this doesn't break in the IDE though.
I don't have time to play with this any longer, but will give it a go at
some later date. If anybody feels like playing around with this
themselves, please go ahead by all means.
Regards,
Colin

I'm not against a choice in AOP, but what do you mean by: > I don't like Spring AOP, I think it's not transparent enough > to client code and it seems always interface/impl combo. Spring allows you to advise classes (using CGLIB) and interfaces (DP). Also, what are you referring to when you say it's "not transparent enough."? |

Hi!
I'm using a factory to create a bean as written in the documentation:
<bean id="exampleBean" class="examples.ExampleBean"
factory-method="createInstance">
...
</bean>
On app startup I get: org.xml.sax.SAXParseException: Attribute
"factory-method" must be declared for element type "bean".
The current spring-beans.dtd at
http://www.springframework.org/dtd/spring-beans.dtd does not contain
the factory-method attribute.
Is the documentation out of date here or is something missing in the
dtd/implementation?
Regards,
Timo

Thank's Guillaume.
I'm studing about the WeakHashMap and I've seen that WeakHashMap build a
weak reference on the key (it's right??), when the key hasn't any reference
the entity is removed by map.
Spring use a class type to save the key. When the class object haven't any
reference? When the Classloader is shutdown?
Can you explain to me (or advise to me if exists an article or tutorial) about?
Thanks,
Claudio

In a quest to figure out why the spurious "closing connection for you, please close it yourself" INFO error messages that some CMT+SpringTx applications exhibited in JBoss 3.2.3, developed into the same INFO message in JBoss 3.2.5, along with an ERROR, I've updated the ejbtest integration sample. There is now a test for calling into a CMT ejb which delegates to a SpringTx wrapped POJO, as well, as one which does this, then delegates to a further SpringTx wrapped POJO which does a Hibernate transaction. I haven't gotten so far as duplicating the connection problem, since I'm getting a situation where Spring is getting a null pointer expression on trying to close a Hibernate Session. This may be a config error of some sort. Will keep digging (since the JBoss connection issue has turned from annoying to dangerous and needs to be pinpointed as either a Spring or JBoss bug), possibly only in a week or so since this has taken too much time already. I do however think these real life integration tests are good for trying to pick up all the obscure stuff we can't unit test, and people using the lib get only under certain combinations of configs.

Hmm, you should actually get a circularity error, since a reference b,
and b references a.
If you are not, then _that's_ what I would consider a bug.

Subject: [Springframework-developer] Possible bug in Spring
Date: Thu, 15 Jul 2004 16:18:53 -0700
From: Andy Depue <an...@ma...>
Reply-To: spr...@li...
Organization: Marathon Computer Systems
To: <spr...@li...>
I may have discovered a bug in Spring, but I want to make sure it is not
already known (and that it is really a bug).
Say you have these beans defined:
----
<bean id="a" class="mypackage.A">
<property name="b"><ref bean="b"/></property>
</bean>
<bean id="b" class="mypackage.B">
<constructor-arg index="0"><ref bean="a"/></constructor-arg>
</bean>
<bean id="c" class="mypackage.C">
<property name="b"><ref bean="b"/></property>
</bean>
----
If you write the code below, you get "different instances":
A a = (A)ac.getBean("a");
C c = (C)ac.getBean("c");
if(a.getB() != c.getB()) {
System.out.println("different instances");
}
---
Basically, bean "b" is instantiated twice, even though it is a singleton. At
the very least, I would want to have an exception thrown rather than Spring
silently creating two instances of "b". I should note that this is against a
version of spring that was obtained from cvs about 3 weeks ago. I currently
do not have time to test against a newer Spring, but thought I'd put this out
there anyway so that if it is known, then I won't spend any more time on the
problem.
Thanks,
Andy

I may have discovered a bug in Spring, but I want to make sure it is not
already known (and that it is really a bug).
Say you have these beans defined:
----
<bean id="a" class="mypackage.A">
<property name="b"><ref bean="b"/></property>
</bean>
<bean id="b" class="mypackage.B">
<constructor-arg index="0"><ref bean="a"/></constructor-arg>
</bean>
<bean id="c" class="mypackage.C">
<property name="b"><ref bean="b"/></property>
</bean>
----
If you write the code below, you get "different instances":
A a = (A)ac.getBean("a");
C c = (C)ac.getBean("c");
if(a.getB() != c.getB()) {
System.out.println("different instances");
}
---
Basically, bean "b" is instantiated twice, even though it is a singleton. At
the very least, I would want to have an exception thrown rather than Spring
silently creating two instances of "b". I should note that this is against a
version of spring that was obtained from cvs about 3 weeks ago. I currently
do not have time to test against a newer Spring, but thought I'd put this out
there anyway so that if it is known, then I won't spend any more time on the
problem.
Thanks,
Andy

I was just browsing thru the docs for the new aspectj support. Looks interesting. Has anybody considered aspectwerkz? Since aspectwerkz already has a spring-container integration, works with simple pojos, does not require a compiler, is configured with attributes and xml, it seems a much cleaner (or at least easier) fit with spring.

As Juergen pointed out, if you find a static member hasn't been garbage
collected, it just means its ClassLoader cannot be garbage collected
yet, the static member is not necessarly at fault there. For an
explanation of the current behavior, see below.
For the solution, you can use a ServletContextListener to call
java.beans.Introspector.flushCaches() when the ServletContext is detroy
(which causes the ClassLoader to be thrown away).
> if (results == null) {
> // can throw BeansException
> results = new CachedIntrospectionResults(clazz);
> boolean cacheSafe = isCacheSafe(clazz);
> if (logger.isDebugEnabled()) {
> logger.debug("Class [" +

> }
> * classCache.put(clazz, new
> WeakReference(results));
> * }
Since Spring 1.0.2, the current code of this method is the following :
if (results == null) {
// can throw BeansException
results = new CachedIntrospectionResults(clazz);
boolean cacheSafe = isCacheSafe(clazz);
if (logger.isDebugEnabled()) {
logger.debug("Class [" + clazz.getName() + "] is " +
(!cacheSafe ? "not " : "") + "cache-safe");
}
if (cacheSafe) {
classCache.put(clazz, results);
}
else {
classCache.put(clazz, new WeakReference(results));
}
}
What the isCacheSafe(Class) method does is check if the clazz's
ClassLoader is the
same as CachedIntrospectionResults, or a parent of it. Because what
prevent garbage
collection of a ClassLoader A is if a class of a ClassLoader B that is
not for garbage
collection has a reference on a class (or instance) of the ClassLoader
A. However, if
A is a parent of B (or B == A), then A cannot be collected anyway.
Which is why if clazz
is considered "cacheSafe", no WeakReference is necessary, and in such
case it improve
performance. For example, if the class introspected is a JDK class, or
a Spring class, its
ClassLoader can never be collected before the CachedIntrospectionResults
class.

I don't know what causes the ClassLoader to be retained, but you cannot
easily know what is the cause, just knowning that singletons instances
are still in the JVM only proves that the ClassLoader has not been
garbage collected. The problem is that something in a parent (or
sibling) ClassLoader still has a reference on a Class of your webapp's
ClassLoader. The trick is to find what is.

I don't like that solution, because it will then also affect any HibernateTemplate that is passed in. The current code does not touch any template that is passed in. These changes do not want to modify that behaviour, but rather allow the default value for allowCreate on _new_ templates created to be specified. And I think there are two ways that people would want to play with the flag: either make their own subclass which sets the flag to false, and that becomes the superclass of all their DAOs, or alternately, do not use a subclass at all, but in some (or all) DAOs, specifically set the default value.
