问题 I want to use JSTL's fmt tag in JavaScript to localize my alert messages. My JavaScript file is a standalone file and when I include fmt tag in js, the file browser gives JavaScript errors.

问题 There are many documentations out there on how to achieve this task but I still couldn't resolve my issue. I'm new to working with servlet so I probably missed something. I use red5 that uses tomcat 6 to create a servlet that uses a spring bean that's of a MysqlDb class for database manipulations. when I point to red5 using port 5080 it acts as a regular tomcat server and i can browse jsp and servlet pages. my web.xml contains the following relevant information: <listener> <listener-class>org

问题 In order to do an SSL Configuration testing under Tomcat, is this all mandatory? This below line is taken from a website: In order to do this for our test, take any application which has already been deployed successfully in Tomcat and first access it through http and https to see if it works fine. If yes, then open the web.xml of that application and just add this XML fragment before web-app ends i.e </web-app> : <security-constraint> <web-resource-collection> <web-resource-name>securedapp<

问题 I'm pre-packaging a JSP web-app that relies on some file path settings found within web.xml. These settings are unknown at packaging time, because they reference a path the customer will set when deploying the entire application (of which the web-app is a management interface). It seems that the easiest way to avoid tokens and file modifications in my installer script, is to ask the user for an install location, set this location as an environment variable (e.g JAVA_HOME), and have web.xml

问题 I have the following error while trying to run my application on WebLogic 12.1.3. The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. This is my web.xml file : <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation=

问题 I am writing a filter to do a specific task but I am unable to set a specific url pattern to my filter. My filter mapping is as follows: <web.xml> <filter> <filter-name>myFilter</filter-name> <filter-class>test.MyFilter</filter-class> </filter> <filter-mapping> <filter-name>myFilter</filter-name> <url-pattern>/org/test/*/keys/*</url-pattern> </filter-mapping> </web-app> My url-pattern [ /org/test/ * /keys/ * ] is not working as I had expected. I am calling urls from the browser like: http:/
