I've been having loads of problems trying to get a Spring/Hibernate web application to generate Jasper Reports. I have a model populated as a HashMap and the report will display the single entries fine: language, format, date, etc. by getting a parameter that corresponds with a key in the model e.g. model.put("language", "en"); - java ...
I am running queries against an Oracle 10g with JDBC (using the latest drivers and UCP as DataSource) in order to retrieve CLOBs (avg. 20k characters). However the performance seems to be pretty bad: the batch retrieval of 100 LOBs takes 4s in average. The operation is also neither I/O nor CPU nor network bound judging from my observatio...

I have a web application running in tomcat where I'm using a ThreadPool (Java 5 ExecutorService) to run IO intensive operations in parallel to improve performance. I would like to have some of the beans used within each pooled thread be in the request scope, but the Threads in the ThreadPool do not have access to the spring context and ...
How can I create a bean of type Class? I found a way using getClass() but that requires an instance and cannot be used via factory-method since it is not static. It also requires an extraneous bean be created for this express purpose: <bean id="foo" class="Foo" /> <bean id="fooClass" factory-bean="foo" factory-method="getClass" /> T...
I have what should be an easy issue to solve, but I'm having no luck. In my servlet-servlet.xml file, I have the following beans (in addition to others): <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <prop...
As you may know, properties are usually written in files in key=value format but can also be written in XML format. The question is if (and how) can Spring's ResourceBundleMessageSource be configured to load properties in XML format. ...
I want to scan all the classes in a package that that are subclasses of the particular class. Then I want to take these classes and for each of them instantiate a bean of same type, using the class as a property. Then I want to gather all these anonymous beans and put them into collection.

For example, with the URL foo.com/bar/99 99 will be available directly to a method in the controller as an argument. The controller is mapped to /bar For anyone familiar with ASP.NET MVC or Django, this would be similar to routes.MapRoute in the former and using (?P\d+) in urlpatterns in the latter. It would be possible to process ...
What I am looking to accomplish is a filter (or similar) that would handle the authentication model for my Spring MVC application. My application is also hosted on Google App Engine. The authentication on this application can tend to be very dynamic and the permissions are not something that would fit cleanly into a predefined Role stru...
Hi guys, While a lot of posts have been written on the subject of Spring's OpenSession/EntityManagerInViewFilter, I couldn't find any that mentions its flaws.
