问题 I have written a web-application in Struts 1 framework. Everything works fine but on form submission when user is forwarded to next page URL which is shown is actionname.do .

问题 I'm trying to test a minimal JAX-RS + EJB/CDI injection mechanism and currently hitting a road-block due to GlassFish unable to inject for whatever reason.

问题 I have installed Tomcat server on my PC and I have added it as a service in Windows. So now it starts each time I boot my computer. Now, in IntelliJ I have configured an application server, and that is my Tomcat server, however when trying to "run" the application it says that the port is already in use....and it is ofcourse since Tomcat is started on boot.

问题 This may sound totally stupid, but is a case of real life :( I'm able to display a HTML table with a "virtual" link name. Something like this: Xyz description <a href="docId=123">document.doc</a> Xyz description <a href="docId=456">documentB.doc</a> Xyz description <a href="docId=798">documentC.doc</a> This doc id represents an id in the database ( for these docs are stored in a blob as byte[] ) Anyway. I'm able to get that id, query the database and retrieve the byte[] ( and even store it in

问题 I know there are many documents available on net which mostly describes technical difference. But I'm rather interested to know what are the common use cases where you prefer one specific type over other any why ? Are those preferences because integration patterns/products support particular type ? 回答1: Thanks for answer. However practical use case difference and when to use what. Both, JAX-WS and JAX-RS have standard implementations. I have come up with the following differences: RESTful

问题 I am writing an application that's sole purpose in life is to do CRUD operations for maintaining records in database. There are relationships between some of the tables/entities. Most examples I've seen for creating session beans deals with complex business logic/operations that interact with many entities which I don't have.
