[opencms-dev] using cms:include from a jsp

[Mario Jäger]

Hi,

I advice the chapter "How to use the OpenCms JSP Taglib" in the Alkacon Documentation to better understand the OpenCms JSP Taglib. If you still have not installed the Alkacon Documentation in your OpenCms, you can download that documentation here: http://www.opencms.org/en/download/documentation.html

I do not know if you have understood the OpenCms basics, because I do not know what you want to reach with your own module and I do not know the content of the jsp files in your module.

But, general it is possible to include a jsp file which renders xml content in another jsp.

How did you implement in your "slide-test-1.jsp" which xml content is to render?

Kind Regards,
Mario.
