context.xml vs web.xml in web application

由 纵饮孤独 提交于 2019-12-18 13:27:17
问题 I am developing a small web application application. The objective is to create one welcome index.html page with Ajax + one servlet to handle ajax requests. Although I thought I would be fine with a web.xml only, I don't want to deploy to / , but to /MyApp . NetBeans's project properties offers options to set a context path, which helps me deploying to /MyApp . However, it automatically adds a /META-INF/context.xml file, which is a bit confusing. My questions are: 1) Do I really need a

Moving contents of META-INF/context.xml to tomcat/conf

问题 We are trying to take the environment specific configuration settings out of our war files, so we can deploy the same war file to dev/test/prod tomcat servers and not have to change the contents of the war config file. When I move the META-INF/context.xml for the database connection to the conf/server.xml the database connection no longer works, with the following error, anyone know why this would be? server.xml: <GlobalNamingResources> .... <Resource url="jdbc:oracle:thin:@hostname:1521

What are steps followed in the look-up? what is looked first web.xml or context.xml?

问题 How does a look-up like : Context envContext = (Context)initContext.lookup("java:comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/MyDatasource"); proceed ? I mean to say how is the name MyDataSource searched and in the end what is returned ? There are two entries added to connect to the database. One in the WEB-INF/web.xml which is : <resource-ref> <description>my connection</description> <res-ref-name>jdbc/MyDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type>

How do I add aliases to a Servlet Context in java?

问题 I have a servlet running under Tomcat. I need to serve some files, I guess we can call them semi-static (which change occasionally ... they are updated by another part of the app) from an external (to the WEB-APP) directory. I have managed to do this by adding the following to my context.xml in the META-INF directory <Context aliases="/working_dir=c:/apache_tomcat_working_dir" ></Context> This works fine, in my HTML I refer to the file as <img src="/myWebbApp/working_dir/fixpermin_zoom.png">

Set Tomcat Default Context Path

由 六月ゝ 毕业季﹏ 提交于 2019-12-07 07:13:12
问题 In my context.xml file I set the following to: <Context antiJARLocking="true" path="/" /> When I run my project from NetBeans then it works correctly and goes to http://localhost:8080/login . Then when I clean & build and go into Tomcat Manager and deploy the war file, for some reason it goes to http://localhost:8080/appName/login . I'm not sure why it's adding the context path or where it even gets it from but when ever I deploy it manually it does that. When ever I run the project directly

问题 I've got a servlet that I wish to deploy programmatically using Jetty. The servlet uses Spring and it's web.xml points to the Spring context XML file as you'd expect.
