Hi I have run my app in another machine and it works, now I am trying to configure it in other machine, and the next message in shown:

library-inclusion-in-archive:
C:\Users\Isaac\Documents\NetBeansProjects\18_03_11 \TiendaStruts\nbproject\build-impl.xml:541: Warning: Could not find file C:\Documents and Settings\Alumno\Mis documentos\lib_Struts1.2.7\antlr.jar to copy.
BUILD FAILED (total time: 0 seconds)


I am working with NetBeans and in my folder Libraries I have in antlr.jar . Anybody knows why it could be happen, in my project no compilation errors are shown.

Thanks in advance.
