any way of modify base directory at runtime?

[Bruno]

Hello all,

Well, I'm using tomcat to run my web application, which loads
dinamically many jars and execute them. My problem is that these jars
sometimes have a method that uses relative paths to do something (read
files, create files, etc). Currently, the current base dir is given
wrong for these loaded applications! Instead of the right path, it's
given "C:\tomcat" or something.

If it were with my Web Application itself, it would be easy to get over
this problem by using the getRealPath("") method provided by api. But
since I can't modify the jar code I will load, what can I do? Some
ideas?

Thanks you!

Bruno

The path should be relative to the webapp directory of the particular
webapp.

Thank you for answer.

Well, I can't modify the path the jar classes is using.
Let me show an example: if the class is trying to read the file
"./file.xml" which is in its current directory, it will not find it.
Instead, it will be accesing C:\tomcat/file.xml that doesnt exists.
Since I cant change the method that reads this file, Id like to change
externally in some way the base path that is considered for this loaded
jar. Maybe I missed it up a bit, but I think it's clearer now.
