I'd appreciate feedback/insight on the following: I have multiple application contexts in the current Java/Spring webapp that I load through the web.xml ContextLoaderListener; is it possible to have multiple application contexts in Grails?...
I implemented Dynamic DataSource Routing for Spring+Hibernate according to this article. I have several databases with same structure and I need to select which db will run each specific query. Everything works fine on localhost, but I am worrying about how this will hold up in real web site environment. They are using some static cont...
We have container transaction with Spring and JPA (Hibernate). I need to make an update on a table to "flag" some rows via native statements. Then we insert some rows via EntityManager from JPATemplate to this table. After that, we need to calculate changes in the table via native statement (with Oracle's union and minus, complex groups....
I have a Spring 2.5 application and I have several forms where I perform various validation.

I was wondering if I could instead put the error message in the form value so it displays in the input field instead of just in th...

In my project I can successfully test database code. I'm using Spring, Hibernate, HSQLDB, JUnit and Maven. The catch is that currently I have to launch HSQLDB manually prior to running the tests. What is the best way to automate the launching of HSQLDB with the technologies being used? ...
I have a file pageLayout.jsp, where the basic structure of each page is laid out, including an HTML title. <title>Project Name</title> Instead of having a static title (like above), I would like to transfer the value of the title of each page to the template. For example, if the JSP page using the template has an H1 element displaye...

Before upgrading to Spring 3 I had this in my applicationContext.xml file: <bean class="com.northgateis.pole.ws.PolePayloadValidatingInterceptor"> <property name="validateRequest" value="${validateRequest}" /> <property name="validateResponse" value="${validateResponse}" /> </bean> where ${validateRequest) and ${va...
I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I trie...

Do you guys have your own little framework for project startups ? I mean, every time one needs to do the same things at the beginning: Context initialization - ideally after arguments are processed. Sometimes without interactive user input, sometimes with input reader. Sometimes we need to load properties, sometimes not. Then we need ...

Hey, I'm wondering how one can do that. Afaik there is BeanFactoryPostProcessor interface that let us use BeanDefinitionRegistry.registerBeanDefinition() method before beans within context are initialized. That method accepts only a class / definition. But usually one needs to register a bean that is already set with properties. Otherw...
I'm being forced to use code values for on-going projects and can't seem to find a good, eloquent solution besides brute force lookups for every code value. Are there any good libraries anyone can suggest, or any good design patterns to retrieve/swap code values? FWIW, I'm in a Spring/Hibernate shop. I had been using a @Codified annot...
Hi, I want to convert some of our internal API into a spring bean spring interceptor that we can use in other projects. This API needs some instantiation and other logic which I want to encapsulate in this bean so that we can just put the bean into our app context with necessary propoerties alone, and this will then apply the logic. I ...
