问题 I'm reading the Spring Web Flow chapter in the book Pro Spring MVC. Unfortunately there's no explicit information, where the state during a flow execution is persisted. I assume it is saved in the JVM Heap and associated with the session. Now HTTP is a stateless protocol (REST...) and I'd like to use Spring Web Flow without saving state on the server (besides the one and only state that a session might be authenticated). One strategy is to send all parameters of the entire flow with every

问题 I have a JSF 1.2/Spring Web flow 2.0.7 app that need to serve binary content (an image). This content is fetched from a web service (along with some other data) as a Base64-encoded string, and ends up in the bean together with the rest of the data. How can I get the image to show on my web page? Note: No, there is no way to make the web service stream the data directly, or even to get the binary data out of the web service without all the other stuff. 回答1: You want to end up with that image

问题 I'm using Spring Web Flow to build an application. I am making use of the Flow Managed Persistence Context so the entity manager is 'kept open' during the execution of my flow and I can access lazy loaded properties (similar to OpenEntityManagerInViewFilter or OpenSessionInViewFilter for Spring MVC). When I use this, every time I submit a form, the number of active database connections increases, if I don't use the FMPC, I have no problems with the number of open connections). I'm working

问题 I am working on spring webflows. I have two webflows in my application, one to add a person details and one to modify the person details. Both flows are working fine.

From the Add flow end state. From outside the flow i.e from anywhere in the application except add flow. 回答1: I figured it out. In
