20. EL - Without FacesContext    coderanch.com

Hi, The Expression Language that is currently used in JSF requires the FacesContext ( associated with the faces request ) for evaluation.

21. What is the use of Facescontext Context Object    coderanch.com

37. solution to read a file from FacesContext    coderanch.com

Even under Windows it's a bad idea to use backslashes in filename paths in Java. Use forward slashes and you'll be OS-independent. More importantly, you won't make mistakes like the one you made, which was failure to escape the filename's backslash character. Since in Java, backslash is an escape character, you have to escape it: "reports\\templates". But "reports/templates" is much tidier. ...
