Strange problem going on here. I'm developing a JSR168 portlet that is using Spring and the Spring form taglib. I have a search form on a page to go through a catalog of reports based on the criteria the user selects, and for the most part it works fine. However, there is one sequence of events that is triggering an error. I have a Jav...
I'm brand spanking new at Spring and have gotten a majority of the knowledge I do have from the Spring Recipes book from Apress. I've got LDAP authentication working with Spring Security within one webapp. I would like to rip out my application context beans and properties files from this one webapp, however, and somehow externalize the...
I have a simple ajax game between 2 users with java backend (tomcat, spring). I need some good way of notifying one user that his opponent made a turn. Now all communication is done through database and waiting for opponent to finish his turn looks like this: while(!timeout && !opponentIsDone) { //...get the game record from db and...
I'm using Spring framework (2.5) and it's AOP features. I've a pointcut expression, like @Pointcut("execution(public * org.springframework.batch.item.ItemReader+.read(..))") public void itemReaderMethods() {} Where the ItemReader interface is a Spring interface and it's signature is: org.springframework.batch.item.ItemReader<T> Th...
I'm trying to set up a Spring JPA Hibernate simple example WAR for deployment to Glassfish. I see some examples use a persistence.xml file, and other examples do not. Some examples use a dataSource, and some do not. So far my understanding is that a dataSource is not needed if I have: <persistence-unit name="educationPU" transaction-ty...

What advantages does EJB have to be stacked with Spring? Why couldn't I just use Spring Entity Manager, Security, and POJOs to do what EJB does? ...

I have used Spring before but I am no expert and only used it for standard web-development previously. Currently, I am working on a project where Spring is being used very differently. It's a stand-alone Swing app which has many displays and the user can switch between a display via a toolbar. When the display changes, all the compo...
I'm integrating these in a basic web application, being deployed in Glassfish. Upon startup, the error I am getting is: nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;) The closest solution I can find has something to do w...
I've always been quite annoyed at some of the apps I now have to maintain that insist on using proxying by class instead of proxying by interface. More specifically, I have service layer classes that are proxied, but I can't make them final (even though they should be) because for some reason someone has decided they should be proxied b...
I currently mark collections in entity beans as eager to avoid getting a lazy initialization exception when I try to access the collection properties after loading the bean with the EntityManager. If I instead leave the collection as lazy loading, how do I keep a session open? I thought about trying @Transactional, but even if that work...
Hi guys, I'm reimplementing a web app in Spring, and I need to expose the business logic with SOAP. I'm going for Spring 3.0, and I'd like to know: what is the recommended way of exposing Spring beans? The rest of my stack is Tomcat 6, JDK 1.6, Struts 2. Cheers Nik ...
How can I test if the Session scope is active in Spring? for example, at startup some classes need a User object which is Session scoped, than i return a mock User object. the bean in question is declared with aop:scoped-proxy. how can i test if the session scope is active? ...
I have a small project that doesn't require much disk space, so i considered using an access database. I was wondering if anyone used a Spring + Hibernate + access combination, if so can they post the connection properties. thanks guys ...
I have an application that has multiple screens and each screen is selected via a button. Each screen contains pretty heavy-weight components so it's important that only the activate screen is in memory - all others should be available for garbage collection. The app uses Spring for the glue and currently it switches screens using getB...
I am using SWFUpload to upload files to java servlet (spring framework). The problem is that the current web session is lost during file upload (it creates a new session). I read that it is a known bug and there are some workarounds somewhere but I can't find anything. Does anyone know how to make it work? Thanks. ...
I loved the 2005 book "Professional Java Development with the Spring Framework" by Johnson. What would be the 2008-9 equivalent of this in terms of the quality and clarity the book provided? Essentially looking for a book for someone new to Spring, I still think the 2005 book is somewhat relevant, but much has changed in the Spring wor...
I decided to use DBCP mainly because I was getting timeouts on my database connections. In theory, once you define a "validation query", DBCP will by default run that query on the connection before using it, so you always know the connection is OK. I set it up two weeks ago and it seemed to work. However, last night I got a timeout exce...
I'm using SimpleJdbcTemplate and MapSqlParameterSource in the folowing way: MapSqlParameterSource parameterSource = new MapSqlParameterSource(); parameterSource.addValue("typeId", typeId, Types.BIGINT); List<Long> ids = _jdbcTemplate.query(_selectIdByParameters, new EntityIdRowMapper(), parameterSource); When typeId ( which is a Long...
