Para referencia futura, debe formatear la salida de la consola como código (sangría cuatro espacios, o simplemente seleccione y haga clic en el icono "101/010" encima de la ventana de edición). Ya he hecho esto por ti en este caso. –

El mensaje de error se muestra en el seguimiento de pila:

Caused by: java.lang.VerifyError: class com.sun.tools.javac.jvm.Target overrides final method . 
    at java.lang.ClassLoader.defineClass1(Native Method) 
    at java.lang.ClassLoader.defineClass(Unknown Source) 
    at java.security.SecureClassLoader.defineClass(Unknown Source) 
    at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:1634)

El problema es que su 'javac' es incompatible con el tiempo de ejecución, probablemente porque está ejecutando un compilador Java diferente del que la JVM ya ha cargado.

Si está utilizando MyEclipse (que no está claro), tal vez eche un vistazo a este blog post. Básicamente, es posible que necesite alinear la máquina virtual utilizada por Tomcat con la utilizada en Eclipse.

hice los cambios como se indica en el enlace, pero todavía. Estoy obteniendo el mismo error. – saloni

Díganos qué jvm está usando su gato, y luego díganos qué jvm está usando su MyEclipse. – John

Mi problema está resuelto. Estaba usando el JRE equivocado. Gracias – saloni

notado la siguiente:

cp = D: \ configuraciones de software \ jakarta-5.0.28 \ common \ lib \ nomenclatura-resources.jar

cp = D: \ configuraciones de software \ jakarta-5.0.28 \ common \ lib \ servlet-api.jar

cp = D: \ configuraciones de software \ jakarta-5.0.28 \ common \ lib \ tools.jar

cp = D: \ software% 20setups \ jakarta-tomc AT-5.0.28 \ bin \ bootstrap.jar

cp = C: \ Program% 20Files \ Java \ jre1.5.0_09 \ lib \ ext \ dnsns.jar

El VerifyError indica que la versión del compilador javac invocado no es compatible con su JDK. Supongo que las herramientas.jar de una versión anterior/posterior de JDK se copiaron en el directorio común/lib de Tomcat, y el tools.jar en common/lib está en conflicto con el del JDK actual.

No sé por qué tools.jar existe en su directorio común/lib, no debería ser necesario allí. (tal vez fue colocado allí para poder ejecutar Tomcat con un JRE en lugar de un JDK)

O bien sáquelo, o si realmente es necesario, copie el de su JDK actual que está utilizando para ejecutar Tomcat sobre este.

Hola chicos También conseguía el mismo problema durante la ejecución de la siguiente

"ant build", ya que no estaba al tanto de este término "Error al iniciar el compilador moderna", por lo corro de comandos con verbos opción Log es decir " hormiga -v acumulación" y, finalmente, conseguir que 'Fuera de error de memoria' para antes de aplicar por favor, aumentar la memoria JRE

así que por favor aplique conjunto ANT_OPTS = -Xms256m -Xmx256m

y luego ejecutar 'problema de generación ant' voluntad obtener la solución

Tuve el problema similar al crear mi proyecto con ANT en IntelliJ Idea IDE. Actualice su versión de JDK. Estaba usando jdk1.7.0_51 y al actualizarlo a jdk1.7.0_65 funcionó.

creo que sirve

Saludos

Se debe a un problema de memoria. Aumente por favor el tamaño de la memoria:

ANT_OPTS="-Xms512M -Xmx1024M"

Espero que esto ayude.
