where is JSTL .tld file?

故事扮演 提交于 2019-12-23 07:15:37
问题 I've downloaded the jstl-1.1.2.jar from a Maven repository. I expected the .jar to contain the .tld file for the tags, but it doesn't. Does anyone know where I can find it? 回答1: JSTL 1.1 consists usually of two files: jstl.jar (the API) and standard.jar (the impl). The TLDs are in the standard.jar . In our JSTL wiki page you can find the right download link for the both JARs. 回答2: BalusC was faster with the correct answer, I just want to add that the standard.jar is also available in maven

问题 The YourKit profiler is used to analyze snapshot. Steps that have been performed (for the only user): generation number has been increased. some actions on the application page have been done. most of them get entities and display them via jstl forEach tag. the logout has been performed (session.invalidate()) the session timeout is set to 5 minutes. consequently I've waited for 6-8 minutes to make sure everything in session is invalidated. the snapshot via YourKit profiler was made.

In my web.xml : <context-param> <param-name>databaseJNDI</param-name> <param-value>jdbc/testDS</param-value> </context-param> What I'm attempting in my JSP file: <sql:setDataSource dataSource = "jdbc/testDS"/> I'm attempting to do this and failing in order to avoid hard-coding the database credentials into the page.
