How do I identify the version of xerces/xalan contained in jar?

[R Arun]

I have 2 jar files each for xerces and xalan. The Manifest files dont have any version info. Is there some way of telling what versions these are?

You can find the version in "Manifest.mf" file. The file would have following entries;
