Fichero .cls

[Yela1603]

Hola!!!

Quiero mandar un artículo a una revista, y para esto me enviaron su formato para pasar el artículo. Entre los archivos que me mandaron se encuentra un fichero llamado RevComEst.cls y otro llamado paper.tex que contiene lo siguiente y es en donde debo escribir el artículo:

\documentclass[]{RevComEst}
\labelpaper[year = 2012, month = 12, volume = , number = , firstpage = 1]

\begin{document}
\title[              ,
       secondtitle = ,
       shorttitle = 
       ]

\begin{authors}
\author[firstname = ,
        surname = ,
        affiliation = {},
        email = ]

\author[firstname = ,
        surname = ,
        affiliation = {},
        email = ]

\end{authors}

\begin{mainabstract}

\keywords{}
\end{mainabstract}

\begin{secondaryabstract}

\keywords{}
\end{secondaryabstract}

\section{Introducción}

%\nocite{*}
%\references{comunicacionesbib}

\end{document}

pero al compilarlo me sale el siguiente error:

! LaTeX Error: File `html.sty' not found.

! ==> Fatal error occurred, no output PDF file produced!

No se a que se deba el error pero imagino que tengo que colocar ese fichero .cls en algún lado para que tex lo pueda reconocer. Si es así ni idea de como hacerlo!!!

Uso Windows 7, TexLive 2011 y TexMaker 3.2.2.

Hola, Yela1603

Lo más sencillo es que pongas el .cls en el mismo directorio (carpeta) en que tienes tu .tex. Sin embargo, el mensaje de error sugiere que es otro archivo el que falta. ¿Puedes poner el enlace al .cls que usas (o ponerlo en algún lado) para darle una revisión?

Hola gm!!! Si, los archivos los tengo en la misma carpeta. Esto es lo que contiene el fichero RevComEst.cls

Hola,

veo algunos problemas con ese archivo; pero bueno, vamos a solucionar tu problema. Primero que nada, el archivo provee la clase comunicaciones.cls, así que ese archivo debes grabarlo con el nombre comunicaciones.cls en la misma carpeta donde esté tu .tex; por supuesto, ahora tu documento .tex debe comenzar con

\documentclass[]{comunicaciones}

y no con

\documentclass[]{RevComEst}

Bien. Ahora, busca dentro de comunicaciones.cls la línea

\RequirePackage{html}

y coméntala; es decir la línea debe quedar así:

%\RequirePackage{html}

guarda los cambios al documento. Finalmente, para poder compilar tu artículo deberás tener la imagen logo-usta.eps en la misma carpeta en la que está tu .tex.
