It's great to see this milestone finally arrive, good job! You mention conversation management as a feature that will be included in 3.0 M3, will it be implemented as a custom scope such as Apache Orchestra's or will it be tightly coupled to Spring Web MVC?

Great News

BTW, if all API is now Java 5 style, How will be the relationship between org.springframework.jdbc.core.simple and org.springframework.jdbc.core? Remember that org.springframework.jdbc.core.simple is already Java 5 style

Always good to see a new milestone!
When will the reference documentation be available? Are there any articles that explain how to use the new Spring MVC REST support?
Thanks.

Thanks for the great work!

Spring 2.5 included a repackaged ASM library, is 3.0 not going to do this? I have a dependency on ASM 3.1… am I out of luck?

I'm a bit confused as to the status of REST support in Spring MVC. Does M2 have this functionality, or is this for a later milestone?

We have an upcoming project that requires REST, and it's either Spring 3 or the ghastly mess that is Restlets. It's all in the timing…

First of all,great job:-)I am thankful

I migrated a project from Spring 2.5.6 to Spring 3.0.0M1 and now it isn´t possible to use the automatic controller detection ().In fact Tomcat couldn´t be started,cause the initialization failed.An Idea why?

Very much looking forward to the validation stuff. What is your plan for integration with a JSON view? Out in the open source community there are already a couple extensions

spring-json http://spring-json.sourceforge.net/
json-lib-ext-spring http://sourceforge.net/project/showfiles.php?group_id=171425&package_id=259636 (an outgrowth of a patch submitted for related to a JIRA.

I posed the question of what direction your planning to go on the JIRA issue:

http://jira.springframework.org/browse/SJS-1

In the meantime, some are rolling there own and others are customizing one of those two solutions. It would be really nice to know which direction Spring 3 will take or if the issue will just be ignored.

Juergen, can you give us a hint about configuring project dependencies for ASM and related libraries, to be able to switch from 2.5 to 3.0.M2?
I want to give a try to Spring 3.0.M2 in my project, especially REST-related things. I've updated spring version and module IDs in my POM file to 3.0.0.M2, but during deployment to Tomcat it blows up at classpath scanning: first I got "ClassNotFoundException: org.objectweb.asm.commons.EmptyVisitor"
then, after adding ASM dependency, I got: "java.lang.AbstractMethodError: org.springframework.core.type.classreading.AnnotationMetadataReadingVisitor.visit".
I'm stuck completely. I've spent whole day trying to find out the necessary setup, but to no avail. From my perspective, Spring 3.0 M2 simply doesn't work at all… I guess many other people will have the same problem.
You say "Now is a good time to give Spring 3.0 an early try!" – and we really want to do it, just give us a clue how to do it!

Well, I've actually tried to add standalone ASM 2.2.3 jars. I got "java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit" exception then. I tried ASM 2.2.3 jars from spring repositories. I got "java.lang.AbstractMethodError: org.springframework.core.type.classreading.AnnotationMetadataReadingVisitor.visit".
I've tried countless combinations, with no lack (I've even reported it in SPR-5557 bug report in Spring JIRA). Unfortunatelly, I'm simply not able to switch from 2.5 to 3.0.M2. And I don't want to wait for M3

How does Spring 3.0 REST support compare to JAX-RS?

I've read that Spring MVC 3.0 is different than JAX-RS, but Spring is a generic framework and I presume its relationship with REST would be somewhat different compared to Spring MVC.

Thank you.

@Grzegorz – it is, but it is a pain actually. First there is no real browsing capabilities due to the underlying Amazon S3 Foo. Furthermore not all libraries seem to be located there. web.servlet can't be resolved, neither can test. Even the libd spring-library thing can be fully resolved.

It's been not moch more comfortable with M1. I actually really want to take a glance at it but if setting up a sample project is so much effort… . Maybe there's someone out there to fix this?

Greets,
Ollie

Seems the repo got stuck for a few minutes… Can resolve the artifacts now. Sorry for inconvenience.

Finally, I was able to run Spring 3M2. I had to change Hibernate dependencies from "plain" ones to OSGI versions from Spring repository, and fix the completely broken joda-time-hibernate library (that I happen to use) dependency declarations.
See detailed description on bug report http://jira.springframework.org/browse/SPR-5557

I've problems with downloading dependencies (using maven) from springsource repository . I added in my project dependency to spring-web (3.0 M2) and when I run "mvn jetty:run" most of dependencies are downloaded properly however these 3 below are missing.

Here is error message:

am I doing something wrong or is repository broken?

Hi Juergen,

What is the situation of the Tiles support in the 3 version? While I am upgrading old version Spring applications to the 3 version, I find the new Spring is not compatible with the previous version in regarding of the Tiles 2 support. In fact, an old code is broken in the new Spring version. And I can't find any related documentation.

I'm curious: How is/should the Exception translation in Spring 3.0 be done? In particular, the JPA implementation of the Clinic (EntityManagerClinic) declares to throw DataAccessExceptions but I have not found any code that translate the e.g. JPA's NoResultException into Springs EmptyResultDataAccessException, nor does the EntityManagerClinic extend any JpaDaoSupport or something like this. Is this done transparently? For which exception should I check in my service methods? Have I missed something?

Thanks in advance.

Hi, Juergen

would u like to talk more about "and also consistent resolution of bridge methods in the Spring AOP API."?
I want to know more details on this, but can't find any useful information,hehe

In Class: SpelAntlrExpressionParser, it has imported some codes from another open source project:

import org.antlr.runtime.ANTLRStringStream;
import org.antlr.runtime.CommonTokenStream;
import org.antlr.runtime.RecognitionException;

Will this dependency be removed before 3.0 GA?

Hello.

I used springframework 3.0.0.M2 in creating an Authorization Filter on a company intranet site. Another office would like to re-use the solution, however, they are running Java 1.4.

I suggested that the other office upgrade to Java 5 (and keep up at least one step behind, not two!) but no dice: they mean to keep Java 1.4!

My own solution was relatively simple, and made use of these classes:
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

Any chance my solution will run on Java 1.4?
