Doubly nested EL variables?

由 北慕城南 提交于 2021-02-04 18:07:34
问题 I'm using Spring MVC for my controller, and JSPs are my presentation layer. Inside my Spring controller, I have: model.put("issues", dataManager.getIssues()); model.put("functions", dataManager.getFunctions()); So now inside my JSP, I have access to ${requestScope['issues']} ${requestScope['functions']} That's all well and good. But in order for my code to be extensible, I would like to store the variable name issues and functions inside the database, which will then be accessible through a

Running JSP files with tomcat 7

由 老子叫甜甜 提交于 2021-02-04 14:12:52
问题 Hi I just installed Apache Tomcat 7 and got the server running OK. When I entered localhost:8089 (8089 being the port I assigned to Tomcat 7) the apache website popped up and I got to run some jsp examples and they opened correctly. However now I wish to create a jsp file myself (I am trying tutorials for the very first time) and when I open them, only the source code I written is showing in the browser. The example I am trying is this: <html> <head> </head> <body> Hello World. <%= new java

Serve JSP stored in DB

由 雨燕双飞 提交于 2021-02-04 13:44:05
问题 I want to server a JSP page that is stored in a database as a blob. So if a request comes in at the url http://mydomain.com/app/list.jsp I know to go to the DB to retrieve the resource list.jsp. I am using spring and tiles, so have adispatcher servlet and controllers set up and working in traditional sense. Would this be similar in principle to the resource servlet that spring web has to serve javascript files and messages from within jar? Note that the JSPs would not just be static HTML, I

How to create the Mongo database connection in context.xml in Java web project?

问题 Although there are many proper tutorials to show how to connect relational database in Java, I really in doubt with the MongoDB mechanism working with Java. Normally people would create a connection in context.xml to interact with a relational database with JSP/servlet to do web project. However, with NoSQL database, I don't quite get any resources on how to perform this connection in a nice constructed way rather than many resources with framework lately and working seamlessly. If any

问题 My web application makes use of a web framework by including the jar (which has compiled JSPs) into the lib. I'm working on migrating from Tomcat 7 to Tomcat 9.

Reloading JSTL Tag files in Tomcat development mode

由 天大地大妈咪最大 提交于 2021-01-29 14:19:45
问题 The application I just inherited defines .tag files - ie JSTL tags written in JSP and other JSTL tags. Is it possible for Tomcat to pick up on changes to .tag files and recompile/reload them without a restart, in the same manner of "development" mode for JSPs? Edit I should have noted that the context is marked as "reloadable" in Tomcat, and I'm successfully hot-deploying class files and jsps. It's just not picking up on .tag files. 回答1: "development" mode for JSPs applies for the tag files
