[opencms-dev] OpenCms/Flex: Fix for "absolute uri ... cannot be resolved" issue

[Alexander Kandzior]

Hi,

this is a simple fix that solves the issue where 
Tomcat can not find the required Taglibs:

This error happens only in some installations. 
Error: Tomcat is not able to find the JSP Taglib TLDs 
which are included in the *.jar files.

This will lead to the following exception when the file
/flexdemo/index.html is opened: 

org.apache.jasper.compiler.CompileException [...] 
This absolute uri (http://java.sun.com/jstl/core) cannot be resolved in 
either web.xml or the jar files deployed with this application. 


This is a Tomcat configuration related issue currently under
investigation. 
In case you encounter this error, please download the file 

http://www.opencms.com/download/flex_taglib_fix.zip

Unpack this file in the /WEB-INF directory of your application. 
The fix will overwrite the web.xml, so in case you made any 
changes there please back this up first. This fix will place 
all required TLDs in the /WEB-INF directory and replace web.xml 
with a version that contains an explicit <TAGLIB> entry for all TLDs. 
After that, Tomcat will be able to find the Taglibs. 

Regards,
Alex.
