Using JSTL, taglibs and custom tags in JSP-alternative projects based on Thymeleaf, Apache Velocity, Apache...












0















I know two facts:



1) EL (later Unified EL) and taglibs (custom tag libraries, including JSTL) are used within JSP and designed specifically for use within JSP.



2) Alternatives to JSP are: Thymeleaf, Apache Velocity, Apache Freemarker, Facelets (within bigger JSF framework). Plus Struts (it is very old, but still is an "alternative").



My question is: a) is it possible and b) is it good practice to use EL and custom tags / taglibs (including JSTL) within projects using JSP alternatives, or they are JSP-specific and cannot be used outside of JSP?



I think that all those can be used in Facelets/JSF, because before Facelets JSF was JSP-based and I still can mix JSP and Facelets. But what about projects with Thymeleaf, Apache Velocity, Apache Freemarker? And Struts2?

Freemarker supports EL and custom tags / taglibs:




Using JSP custom tags in FTL
FreemarkerServlet puts the JspTaglibs hash into the data-model, which you can use to access JSP taglibs. The JSP custom tags will be accessible as plain user-defined directives, and the custom EL functions (since FreeMarker 2.3.22) as methods.




Also Spring moved from Velocity to FreeMarker as default template engine




Velocity Templating support was being phased out in favor of FreeMarker.




Notice also FreeMarker is no longer in incubation status in Apache projects




The FreeMarker project graduated on 2018-03-21
