"Unable to read TLD META-INF/jsf_core.tld from jsf-impl-2.0.jar" error when integrating JSF

We have a Struts+Spring+Hibernate Application and we are trying to integrate JSF. For that we have done some configuration in web.xml and struts-config.xml. I have added some JAR files to WEB-INF/lib.

The jar files containing in my WEB-INF/lib are listed here:

antlr-2.7.6rc1.jar,asm.jar,asm-attrs.jar,bsh-2.0b2.jar,c3p0-0.9.1.2-jdk1.3.jar,cglib-2.1.3.jar,commons-beanutils-1.7.jar,commons-betwixt-0.8.jar,commons-cli-1.0.jar,commons-codec-1.3.jar,commons-collections-3.jar,commons-dbcp-1.2.1.jar,commons-digester-1.7.jar,commons-discovery-0.2.jar,commons-fileupload.jar,commons-httpclient-3.1.jar,commons-io-1.3.1.jar,commons-lang-2.3.jar,commons-logging-1.1.jar,commons-pool-1.2.jar,commons-validator.jar,connector-1_5.jar,dom4j-1.6.1.jar,ehcache-1.1.jar,el-api-6.0.20.jar,el-impl-2.2.0-SNAPSHOT.jar,hibernate-3.1.3.jar,jetty-util-6.0.0,.jar,servlet-api-2.3.jar,spring-2.5.6.jar,standard.jar,struts.jar,xercesImpl-2.6.2.jar,xmlParserAPIs-2.6.2.jar,xstream-1.3.1

The below jar file are the ones newly added for integrating JSF:

jsf-api-2.0.jar,jsf-impl-2.0.jar,myfaces-jsf-api-1.0.9.jar.jar.jar,struts-faces-1.3.10.jar

I am using Spring source toll suite, Tomcat 5.5 and JDK 1.5. My Tomcat 5.5\common\lib contains JAR files

commons-el.jar,jasper-compiler.jar,jasper-compiler-jdt.jar,jasper-runtime.jar,jsp-api.jar,naming-factory.jar,naming-factory-dbcp.jar, naming-resources.jar,servlet-api.jar

My Server is starting properly but not able to load JSP page, I am getting the exception as

org.apache.jasper.JasperException: Unable to read TLD "META-INF/jsf_core.tld" from JAR file "file:/SSHIntgr/WEB-INF/lib/jsf-impl-2.0.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: com.sun.faces.taglib.jsf_core.CoreValidator

How can I solve this?

You're using tomcat 5.5 which is a Servlet 2.4 container, but JSF 2.0 requires Servlet 2.5 or newer.

So you have 2 options:

• Upgrade your servletcontainer to a Servlet 2.5 comparible one (e.g. Tomcat 6.0).
• Downgrade JSF to 1.2 which is compatible with Servlet 2.4.

---

Unrelated to the concrete problem: the file servlet-api-2.3.jar does not belong in WEB-INF/lib. Get rid of it. It's supposed to be already provided by the servletcontainer (in this case, the one in Tomcat's /lib). Keeping this file will only lead to missing class def or abstract method errors during runtime.
