Configuration tomcat (pour les experts)

Salut,

Ceci concerne la configuration de tomcat servelets/jsp container.

Dans l'installation des outils avant de compiler la source tomcat, j'ai un pb lors de l'installation du parser xerces...
je n'arrive pas à comprendre ce passage
"
* Unpack the binary distribution into a convenient location so that the
distribution resides in its own directory (conventionally named
"xerces-x_y_z").

* In your build.properties file, you will need to set properties differently
based on which version of Xerces you are using:
- For versions 1.3.1 up through and including 2.0.0beta3,
set the "xerces.jar" property to point at the full
pathname of the corresponding file.
- For version 2.0.0beta4 and later, set the "xmlParserAPIs.jar"
and "xercesImpl.jar" properties to point at the corresponding
files
- If you have defined both sets of properties, the newer (two files)
packaging will be loaded into the Tomcat you are building
"

mon pb c'est, de quel fichier build.properties il s'agit?

merci
