What is the most concise way of making sure that a Spring bean has all properties set and the init method called? I'll favour answers which use setter injection and XML configuration, since that's what I'm using right now. I'm trying to evade the case where I either forget to configure a setter or call the init-method. In future ...
I have some tests that load up some Spring context files. When I run the tests from my ant target they work as expected. When I run them from IntelliJ I get a NotWritablePropertyException. I initially figured different classpaths, but the only differences are for IntelliJ's test runner. Caused by: org.springframework.beans.NotWritablePr...
I have a user object that has a one-to-many relationship with String types. I believe they are simple mappings. The types table hold the associated user_id and variable type names, with a primary key 'id' that is basically a counter. <class name="Users" table="users"> <id column="id" name="id" /> ... <set name="types" table=...
Spring roo is new framework and I found it very interesting. I have been working on web application for last 3-4 years and Always found JSPs are hard to maintain across teams if everyone is not disciplined enough about separation of markup and serverside logic. I have used JackBe/BackBase in last projects and I enjoyed xml templates work...
I have a number of DAO classes that extend SqlMapClientDaoSupport, and call getSqlMapClientTemplate() to run iBatis queries. For a particular test, I wish to replace the object returned when each DAO calls getSqlMapClientTemplate(), with my own custom class. How can I do this? I know that there is a setSqlMapClientTemplate( org.sprin...

So I made modelAndView return type to "GET", "POST" methods. But, Request lost commandObject, form:errors..., if request return showForm ...
I have a FileSystemXmlApplicationContext and I would like the beans defined in the XML to take as a constructor argument a bean which is not declared in Spring For example, I would like to do: <bean class="some.MyClass"> <constructor-arg ref="myBean" /> </bean> So I could imagine doing this via something like: Object myBean = .....

One of the most difficult things about understand Spring is that Spring supports multiple approaches to the same problem. So in my application I using injected EntityManager using the @PersistanceContext annotation, for example: @Repository public class JpaDao extends JpaDaoSupport implements Dao { @PersistenceContext(unitName = "...
I'm currently working on building a java web app. I've been looking to use Spring and Hibernate so I get some proper exposure to them, but I'm just getting burned out reading and learning about them. If I go ahead and build it with JSP and Servlets on a MySQL back end, what kind of levels of code reuse would I be looking at? I imagine th...

Hi, We are trying to implement Oracle connection pooling with the help of Spring Framework. We are using DBCP connection pooling method. However the integration between DBCP and spring doesn't go down that well. Problem that we face is that DBCP returns PoolableConnections Object while Oracle expects OracleConnection Objects. (Thorws C...
If I have no to little experience in either of them, but know enough Java and Ruby to be comfortable, is one framework harder to learn than the other? Is one easier to use for the beginner on these? I know it is hard to answer. Just looking for general thoughts on it. ...
Hi, I have many cookie-cutter spring beans and don't want to explicitly define each one in xml. So I went the component scanning route which lets me do this. This is nice, but I just realized that MyBeanPostProcessor isn't being called for the beans loaded in using the component-scan technique. MyBeanPostProcessor simply attempts to...

The actual question is: Is there a way to get XmlWebApplicationContext to load resources using paths relative to the context location? For clarity's sake, let's say "context location" is the location of the first file specified via setConfigLocation() method. Detailed explanation is below: I'm using Spring MVC in web tier and Spring...

Hi all, I understand the IOC concept, which we can mix-and-match different classes using wiring. Every class can get away from hard code it's dependancy by delegating the wiring / relationship handling to base xml (context xml). Here is my question, why do we use xml? we can simply wire all the components by using java class. Instead o...
