[opencms-dev] Taglib configuration

[Ernesto De Santis]

Hi Joe

This is the standard way (but...):

---------------------------------------

A better solution is to bundle the tld WITH your jar file.
For an example, take a look at the JSTL and how that is bundled.

You have to
1 - declare a <uri> element in your tld file
eg from JSTL:

<taglib>
  <short-name>c</short-name>
  <uri>http://java.sun.com/jstl/core</uri>
...
  

2 - include the tld file in the /META-INF of the jar file
3 - import the taglib into your pages using the uri defined in the tld file.

This way, all you need is the jar file somewhere in the classpath
- No entries in web.xml
- No tld files lying around.

Much simpler don't you think?

Cheers,
evnafets

--------------------------------------

But..., this don't work for me in opencms. :(
I don't know for what. I try in another context, and work fine.

If you get the solution, let me know please.

The other way is:
- copy the .tld to WEB-INF folder
- edit the web.xml file adding this tag:

    <taglib>
        <taglib-uri>http://www.opencms.org/taglib/cms</taglib-uri>
        <taglib-location>/WEB-INF/opencms.tld</taglib-location>
    </taglib>

- in your jsp use the uri for the taglib location.

Bye,
Ernesto.


Regards,
Ernesto.
