What a danged PITA! This is MUCH harder to implement than any other version of JSTL. In your JSP, you need to have this PRECISE line, formatted exactly as I have it or else Eclipse will whine that it doesn’t recognize the c:blah tags: Make sure you do not place copies of these JARs in your WEB-INF/lib directory because they would in that case be sent to the server thereby causing LinkageErrors. You have those three JARS and no other JSTL or Servlet JARS on your classpath. Your web.xml has the right namespace for the Servlet 3.0 spec Please note! This exact configuration only applies if you are using the magic combination of:Ī Servlet 3.0-compliant application server such as Tomcat 7 įinally, in case Maven can’t find those JARS, you can make Eclipse happy by including three JARS with your project and doing the usual Project–> Properties–> Java Build Path and include them that way–though Maven should take care of it. Unless you stop that from happening, you will be in a whole world of pain. What is happening is the JSTL 2.1 Jars are actually pulling in the wrong versions of the Servlet spec–2.5. JSTL 2.1 + Tomcat 7 + Servlet 3.0 is very broken unless you fix it by using these lines, especially the exclusion part. If you’re using Maven, your pom.xml should have these lines. If you desire to use the Servlet 3.0 spec, you must have your web.xml as follows: I am using Tomcat 7, which is a Servlet 3.0-compliant server. I have been fighting with this for several hours. What should I do to solve the problem and make this application run? Maybe I should not include those jars and use a different JSTL url? Mine is for JSTL 1.1 I think, is there a new URL for JSTL 1.2? I did some googling, but I couldn’t sort it out, some said it could be caused by conflicting versions of the jars. : /jsp/index.jsp (line: 3, column: 62) Unable to read TLD “META-INF/c.tld” from JAR file “jndi:/localhost/cp/WEB-INF/lib/standard.jar”: : Failed to load or instantiate TagLibraryValidator class: .tlv.JstlCoreTLV
When I tried to upload standard.jar and jstl.jar I had the following error: Tomcat 7 has “Spec versions: Servlet 3.0, JSP 2.2, EL 2.2”, so JSTL is not included? SEVERE: rvice() for servlet in context with path threw exception If you were using Gradle, you could write in a build.I wrote a web application with Eclipse Tomcat and it works on my local Tomcat 7, when I tried to publish it online on a Tomcat 7, I had the following error: If you are using Maven, make sure you have the dependency for jstl artifact:Ģ. To fix it, declares jstl.jar in your Maven pom.xml file.ġ. The error is telling you it cannot find the class because it is not available in your application.īy default, Tomcat container doesn’t contain any jstl library. : .core.ConfigĪt .WebappClassLoader.loadClass(WebappClassLoader.java:1714)Īt .WebappClassLoader.loadClass(WebappClassLoader.java:1559)Īt .(JspViewDeclarationLanguage.java:91)Īt .RenderResponseExecutor.execute(RenderResponseExecutor.java:78)Īt .LifecycleImpl.render(LifecycleImpl.java:241)Īt .service(FacesServlet.java:199)Īt .ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305)Īt .ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210)Īt .StandardWrapperValve.invoke(StandardWrapperValve.java:222)Īt .StandardContextValve.invoke(StandardContextValve.java:123)Īt .AuthenticatorBase.invoke(AuthenticatorBase.java:472)Īt .StandardHostValve.invoke(StandardHostValve.java:171)Īt .ErrorReportValve.invoke(ErrorReportValve.java:99)Īt .AccessLogValve.invoke(AccessLogValve.java:936)Īt .StandardEngineValve.invoke(StandardEngineValve.java:118)Īt .rvice(CoyoteAdapter.java:407)Īt 11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1004)Īt $AbstractConnectionHandler.process(AbstractProtocol.java:589)Īt .net.JIoEndpoint$n(JIoEndpoint.java:310)Īt .runWorker(Unknown Source)Īt $n(Unknown Source)
