untime - Template processing error: \"No mapping d

问题:

My current development environment is java 6, spring framework 3.2, weblogic 10.3.6 and using Freemarker templates. Everything is working fine in current environment, don't see any runtime issues while browsing pages.

IDE: eclipse kepler 4.3 and I am running weblogic server from eclipse IDE. My deployment assembly is from m2e plugin that comes with kepler.

Now I am upgrading to latest Weblogic 12.1.2 and java 7. I am able to successfully build, deploy and publish the module but while accessing pages, I see runtime issues with freemarker templates.

There is a related issue discussed in forum for tomcat deployment wherein solution is to add spring-security-taglibs to pom file and place spring-security-taglibs.jar in WEB-INF/lib folder. But that does not work for me.

Greatly appreciate any help in resolving this issue. I see many freemarker template exception related postings but not solution.

Below is the runtime error, I am seeing.

2013-09-23 14:16:30,696 [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] ERROR freemarker.runtime - Template processing error: "No mapping defined for http://www.springframework.org/tags"

The problematic instruction:

Java backtrace for programmers:

freemarker.template.TemplateModelException: No mapping defined for http://www.springframework.org/tags

Sounds like FreeMarker's JSP extension haven't discovered the TLD file that contains <uri>http://www.springframework.org/tags</uri>. It looks for it under /WEB-INF/*.tld and /WEB-INF/lib/*.{jar,zip}/META-INF/*.tld. If it's not there and you don't want to put it there, you can map that URL to the TLD file location in the web.xml with the taglib element.

Was this issue ever resolved? If i deploy the WAR externally from WL admin console, everything works fine and no freemarker template error. I am running into similar errors when deploying WAR from Eclipse (Mars) , Weblogic 12.2.1. Workaround is to copy TLDs to WEB-INF and then deploy from eclipse I get no errors. However, there shouldn't be a need to copy these TLDs as they are in the JAR files under WEB-INF/lib.
