In Portal 7 version, taglib description files (.tld) files are not available under
the wps.ear/wps.war/WEB-INF/tld. (Ha vent find anywhere directly
under installed folder).
<%@ taglib uri="http://www.ibm.com/xmlns/prod/websphere/portal/v7.0/portal-fmt" prefix="portal-fmt" %>
<%@ taglib uri="http://www.ibm.com/xmlns/prod/websphere/portal/v7.0/portal-core" prefix="portal-core" %>
Unable to find taglibs & this problem with the WP7 taglib uri references when I was developing
the Custom Theme ,but solved this by exporting theme as war using the EARExpander tool and import into RAD
and update the custom code and deploy that WAR file. It will resolve the
taglib references problem.
But actual solution to resolve the taglib references problem in the WP7
is to copy the empty decorations.xml file under the WEB-INF folder of
web application(custom theme).This will make sure to get the all tagLib
references at runtime.
