Incrementar el tamaño máximo del POST de Tomcat

Servicios

Un equipo de desarrollo quería usar el Manager App de Tomcat para desplegar de los war). Aunque al intentar subir war de más de 50MB les arrojaba el siguiente error Message: FAIL - Tried to use command /upload via a GET request but POST is required.

El log manager.log registró el siguiente error:

Solución

La solución pasa por incrementar el tamaño máximo del POST de Tomcat, en este ejemplo a 100MB (104857600 bytes) así como del Manager App editando los siguientes archivos:

  • Tomcat: Editar el archivo /conf/server.xml y añadir el atributo maxPostSize="104857600" al conector de Tomcat.
  • Manager App: Editar el archivo webapps/manager/WEB-INF/web.xml y modificar los parámetros
