    copied!<p>I am trying to deploy to tomcat 7 a little Spring MVC app, and I am getting the dreaded exception:</p> <pre><code>java.lang.NoClassDefFoundError: javax/el/ExpressionFactory org.apache.jasper.runtime.JspApplicationContextImpl.getExpressionFactory(JspApplicationContextImpl.java:108) org.apache.jasper.compiler.Validator$ValidateVisitor.&lt;init&gt;(Validator.java:514) org.apache.jasper.compiler.Validator.validateExDirectives(Validator.java:1795) org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:217) org.apache.jasper.compiler.Compiler.compile(Compiler.java:373) org.apache.jasper.compiler.Compiler.compile(Compiler.java:353) org.apache.jasper.compiler.Compiler.compile(Compiler.java:340) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:646) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:357) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) </code></pre> <p>I don't see any usual suspects in my WEB-INF/lib that is deployed (servlet-api.jar, el-api.jar, etc.).</p> <p>Here is my pom.xml file:</p> <pre><code>&lt;!-- Servlet --&gt; &lt;dependency&gt; &lt;groupId&gt;javax.servlet&lt;/groupId&gt; &lt;artifactId&gt;servlet-api&lt;/artifactId&gt; &lt;version&gt;2.5&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;javax.servlet.jsp&lt;/groupId&gt; &lt;artifactId&gt;jsp-api&lt;/artifactId&gt; &lt;version&gt;2.1&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;javax.servlet&lt;/groupId&gt; &lt;artifactId&gt;jstl&lt;/artifactId&gt; &lt;version&gt;1.2&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; </code></pre> <p>I am basically trying to load a simple jsp page. I know that Tomcat is choking compiling the jsp page using Jasper because it is hitting this Class Loader issue, but I can't figure out why.</p> <p>My only guess is that either I need to package a library that I am not, or perhaps add a library to the tomcat/lib.</p> <p>Here are the list of jars in my WEB-INF/lib</p> <pre><code>activation-1.1.jar antlr-2.7.6.jar aopalliance-1.0.jar aspectjrt-1.6.6.jar aspectjweaver-1.6.6.jar commons-collections-3.2.jar commons-dbcp-1.2.2.jar commons-fileupload-1.2.1.jar commons-io-1.4.jar commons-lang-2.1.jar commons-logging-1.1.1.jar commons-pool-1.3.jar dom4j-1.6.1.jar ehcache-core-2.3.0.jar freemarker-2.3.15.jar groovy-all-1.8.5.jar guava-12.0.jar hibernate-commons-annotations-4.0.1.Final.jar hibernate-core-3.3.1.GA.jar hibernate-entitymanager-4.1.0.Final.jar hibernate-jpa-2.0-api-1.0.1.Final.jar hibernate-validator-4.1.0.Final.jar hsqldb-1.8.0.7.jar jacks_2.10-2.1.4.jar jackson-annotations-2.1.4.jar jackson-core-2.1.4.jar jackson-core-asl-1.9.9.jar jackson-databind-2.1.4.jar javassist-3.15.0-GA.jar javax.inject-1.jar jboss-logging-3.1.0.CR2.jar jboss-transaction-api_1.1_spec-1.0.0.Final.jar jcl-over-slf4j-1.6.6.jar jettison-1.1.jar joda-time-1.6.2.jar jsr305-1.3.9.jar log4j-1.2.17.jar logback-classic-1.0.7.jar logback-core-1.0.7.jar mail-1.4.6-rc1.jar mysql-connector-java-5.1.18.jar ognl-3.0.5.jar scala-compiler-2.10.1.jar scala-library-2.10.1.jar scala-reflect-2.10.0.jar scalap-2.10.1.jar slf4j-api-1.7.5.jar slf4j-log4j12-1.6.6.jar snakeyaml-1.11.jar spring-aop-3.2.2.RELEASE.jar spring-batch-admin-manager-1.3.0.BUILD-20130514.094516-16.jar spring-batch-admin-resources-1.3.0.BUILD-20130514.094516-17.jar spring-batch-core-2.2.0.BUILD-20130514.030108-700.jar spring-batch-infrastructure-2.2.0.BUILD-20130514.030108-714.jar spring-batch-integration-1.3.0.BUILD-20130514.094516-17.jar spring-beans-3.2.2.RELEASE.jar spring-context-3.2.2.RELEASE.jar spring-context-support-3.2.2.RELEASE.jar spring-core-3.2.2.RELEASE.jar spring-expression-3.2.2.RELEASE.jar spring-integration-core-2.2.3.RELEASE.jar spring-integration-file-2.2.3.RELEASE.jar spring-integration-groovy-2.2.3.RELEASE.jar spring-integration-http-2.2.3.RELEASE.jar spring-integration-jms-2.2.3.RELEASE.jar spring-integration-jmx-2.2.3.RELEASE.jar spring-integration-mail-2.2.3.RELEASE.jar spring-integration-scripting-2.2.3.RELEASE.jar spring-integration-stream-2.2.3.RELEASE.jar spring-integration-twitter-2.2.3.RELEASE.jar spring-integration-ws-2.2.3.RELEASE.jar spring-integration-xml-2.2.3.RELEASE.jar spring-jdbc-3.2.2.RELEASE.jar spring-jms-3.2.2.RELEASE.jar spring-oxm-1.5.9.jar spring-oxm-3.2.2.RELEASE.jar spring-retry-1.0.2.RELEASE.jar spring-scala-1.0.0.M2.jar spring-security-config-3.2.0.M1.jar spring-security-core-3.2.0.M1.jar spring-security-crypto-3.1.0.RELEASE.jar spring-security-web-3.2.0.M1.jar spring-social-core-1.0.1.RELEASE.jar spring-social-twitter-1.0.1.RELEASE.jar spring-tx-3.2.2.RELEASE.jar spring-web-3.2.2.RELEASE.jar spring-webmvc-3.2.2.RELEASE.jar spring-ws-core-1.5.9.jar spring-xml-1.5.9.jar thymeleaf-2.0.15.jar thymeleaf-layout-dialect-1.0.5.jar thymeleaf-spring3-2.0.15.jar wsdl4j-1.6.1.jar xml-apis-1.0.b2.jar xpp3_min-1.1.4c.jar xstream-1.3.jar </code></pre>
