I have establish my enviorement variables in the web.xml file (connection string, etc...)
I also want to establish a Vector as a configuration variable of my application, but the <env-entry> tag doesn´t support Vector class.
Any idea??
Thanks in advance.

Still rummaging around for details.

In the mean time.  Do you need to fully qualify it, ie. "java.util.Vector"?

Aha.  No, you can only have:

java.lang.Boolean, java.lang.Byte, java.lang.Character, java.lang.Double, java.lang.Float, java.lang.Integer, java.lang.Long, java.lang.Short, or java.lang.String.

What do you need to store in the Vector?  It sounds like you might be stretching the purpose of environment variables ;-)

The vector will store strings.
I am reading something about a <resource-ref> tag in web.xml...

the direct answer to you question is NO, you can do Vector in env-entry. the alternative will be:
option 1. use comma separated string and parse it later in your code.
option 2. serialize you vector in a resource file and use getResourceAsStream() to load it back to you app.

I only want to store a list of strings, it doesn´t matter if the strings are store in a vector or not.

then, the easiest is to separate the strings with comma in one env-entry. and use StringTokenizer to read them back.
