Ese error te da por que en el CLASSPATH no tienes el jar tools.jar

Este .jar viene con el JDK de Java, para solucionarlo localiza ese archivo y muevelo a RESIN_HOME/lib

al correr el servicio me da el sigueinte mensaje:
===========================================
500 Servlet Exception

Resin can’t load com.sun.tools.javac.Main. Usually this means that the
JDK tools.jar is missing from the classpath, possibly because of using
a JRE instead of the JDK. You can either add tools.jar to the classpath
or change the compiler to an external one with
or jikes.

java.lang.ClassNotFoundException: com.sun.tools.javac.Main in DynamicClassLoader[JarLoader[]]

==================================================
alguna sujerencia ?
Gracias
Juan

te comento, no soy maestro de linux pero baje la version de Resin en .deb
-la instale
-al iniciar el servicio me dijo que no existia un archivo de tipo conf. ( no pude dar start al servicio )
-baje la version de acuerdo a lo que dices aca,
-la isntale todo perfecto…
-inicie el servicio voy a ver por http://localhost:8080 y me aparece el mensaje que expuse…

Esos fueron todos los pasos..

Gracias por tu respuesta…

me interesa montar resin por las posibilidades que le veo en unos desarrollos que prentendo hacer.

Saludos

Juan
