no puedo compilar PageTag.class

[no-name]

Buenos dias, se que tenia que poner un titulo curioso para ver si me echais una mano a entender java.

No os voy a engañar yo soy mas de PHP C++ y cositas asi, donde los compiladores funcionan a la primera y no necesito volverme picha, bien la cuestion es la suiguiente, queria modificar la parte de abajo de alfresco para quitar lo que no tiene garantia ni nada, para poner que es mi empresa la que se encargara del soporte de ese alfresco, un numero de telefono la web tal y cual, y seguido los siguientes pasos:

-Buscar el jar correspondiente en este caso: alfresco-web-client.jar
-Lo descomprimo para podes trabjar con el
-edito el archivo que tiene esta clase: org/alfresco/web/ui/repo/tag/PageTag.class (para esto uso un decompilador llamado DJ Java Decompiler)
-Lo guardo como PageTag.java

Hasta aqui no hay ningun problema, todo se hace correctamente.

entonces me voy al cmd (bash shell o como se llame esa cosa negra de windows)y yo con toda mi ilusion escribo:
javac PageTag.java

A lo que el me dice para desilusionarme:

51 errors

y yo me quedo con cara de  :shock:

Alguien me esplica un poquito en que estoy metiendo la pata, porque me imagino que durante este proceso e tenido que cometer algun error

[pjcaracuel_2349]

Buenas,

Asi a simple viste decirte que no has incluido el classpath en la compilacion, echale un vistazo a este post, sino en google seguro que encuentras infinidad de post.

Muchas gracias, esto me resuleve una duda, que es cual era mi fallo, ahora seme plantea otra.

Caules son los compiladores que necesitaria para esto, bien me esplicare un poquito yo tengo el path definido, y creo haberlo hecho bien porque cuando le digo javac me saltan todas las opciones que tengo, tambien alado del JDK 1.6.0_12 tengo una carpeta que se llama jre6 que es la que creo que usa alfresco y dentro de bin hay un monton de .dll (que si no estoy equivocado es donde se define lo que a mi me da errores)

Ahora no tengo muy claro como definir o decirle que use estos tambien para que no salte errores, me podeis guiar un poquito mas, o decirme si solo con el jdk 1.6 no me vale y necesito bajarme e intalar alguna cosilla mas


Muchas gracias de antemano.

Buenas,

No necesitas bajarte nada mas, yo uso eclipse para desarrollar, pero si te creas una variable de entorno CLASSPATH y le asignas un valor tal que p.e. C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib te deberia funcionar.

E probado

C:\Documents and Settings\usuario\Escritorio>JAVAC -classpath C:\Alfresco\tomcat\w
ebapps\alfresco\WEB-INF\lib -classpath c:\Alfresco\tomcat\webapps\alfresco\WEB-INF\clas
ses PageTag.java

C:\Documents and Settings\usuario\Escritorio>JAVAC -classpath C:\Alfresco\tomcat\w
ebapps\alfresco\WEB-INF\lib PageTag.java

C:\Documents and Settings\usuario\Escritorio>JAVAC -classpath c:\Alfresco\tomcat\webapps\alfresco\WEB-INF\clas
ses PageTag.java

y la respuesta es la misma 51 errores.

No entiendo, que tengo mal configurado, esque a mi me parece que es algo que no tengo bien definido, pero esque no se que puede ser.

[pjcaracuel_2349]

Buenas,

Entiendo que porque tendras que añadir los .jar que necesites, revisa esta entrada sobre el uso de la variable CLASSPATH
