El servidor Tomcat no se iniciará en eclipse debido al servlet

Question

Estoy escribiendo un programa que analiza un archivo XML en objetos Java utilizando smooks. Me han pedido que ejecute esto como un servlet. La aplicación (antes de convertirla a un servlet) funcionó bien, pero el servidor tomcat falla cada vez que intento ejecutarlo. Ahora he ejecutado un servlet de ejemplo sin problemas.

Aquí está la consola en el arranque:

Reescribí el programa en vano, sin embargo el error que hablabas antes ("byte de etiqueta válida en la piscina constante") se ha ido. esta vez, no hay nada en mi carpeta WEB_INF/lib.

Answer 1

org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 60 

Esto puede tener varias causas posibles que están todos relacionados con una versión de la API Servlet incompatibles ser utilizados durante la construcción.

Lo más probable es que tenga un archivo JAR específico de servlet ofensor como servlet-api.jar o más desde un servletcontainer arbitrario de una marca/versión diferente en su webapp's /WEB-INF/lib. Debes eliminarlo. No pertenece allí. Si lo hizo para "corregir" errores de compilación en Servlet API, lea esta respuesta cómo hacerlo correctamente para Eclipse + Tomcat: How do I import the javax.servlet API in my Eclipse project?

Otra causa probable es que el proyecto Eclipse se configura con un error " Módulo web dinámico "faceta versión. Debe asegurarse de que esté configurado en 3.0 (ya que Tomcat 7.0 es un contenedor Servlet 3.0). Haga clic derecho en proyecto, vaya a Propiedades> Facetas de proyecto> Módulo web dinámico y asegúrese de que esté configurado en la versión 3.0.

De nuevo, otra posible causa (pero esto sería menos probable que la OMI cause esta excepción en particular) es que el web.xml está declarado por sí mismo según la versión incorrecta de la API Servlet. Asegúrese de que la declaración raíz <web-app> cumpla con la especificación de Servlet 3.0.

<web-app 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
    version="3.0"> 

---

actualización: si todo parece correcto, entonces la causa del problema es probablemente en la tercera parte sí JAR (muy probablemente el de Smooks). Le gustaría informarlo como un error para sus mantenedores. Mientras tanto, si no tiene ningún JAR que requiera el escaneo de anotaciones de Servlet 3.0, puede desactivar el escaneo de anotaciones en archivos JAR agregando el atributo metadata-complete="true" al <web-app> entery en web.xml.

<web-app 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
    version="3.0" metadata-complete="true"> 

Answer 2

veces si está ejecutando un servidor Tomcat en Eclipse, el directorio de trabajo Tomcat local puede obtener jacked y hay que aclarar explícitamente. Tenga en cuenta que esto no es lo mismo que hacer una generación limpia en el proyecto: servidores abiertos Ventana-> Haga clic derecho sobre el servidor-> Limpio Tomcat trabajo Directorio ...-> Aceptar

Answer 3

que estaba usando Tomcat 7.0.27 . Al migrar mi máquina a otra con Win7-64 bits, comencé a tener este error al iniciar Tomcat. Como esta publicación (org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15 - Tomcat 7, JDK incompatibilty?), acabo de actualizar el Tomcat a 7.0.61 que resolvió mi problema.
