You can't use a value returned from the XSLT while the JSP is running, because the JSP *outputs* the XSLT -- which means the XSLT is executed after the JSP. What you have here will essentially be the same as: <% getTelephoneNumber("\n <xsl:value-of select=\"value\"/> \n"); %> which is probably not what you want. You will have to do one of three things: * If you are making an HTML page, then you will have to do something like this in your XSLT: <input type="hidden" name="phone" value="{value}"/> which uses an Attribute Value Template that will output the phone number into the <input value="..."/>. You then have to put that into a <form> and make the user click "submit" to return the value to the server where you can do more processing -- pretty ugly. * Check out the Cocoon project (http://xml.apache.org/cocoon), and convert all of your .jsp files to .xsp. This is a totally new language, so converting won't be easy, but it *might* be able to do what you want (emphasis on *might*, since you still won't be able to use XSLT directly in the page) * Use your processor's extension mechanism to be able to access getPhoneNumber() in the XSLT, so you can do something like: <xsl:value-of select="xx:getPhoneNumber(value)"/> This is probably the best way to go, but it depends on a lot of other factors such as the processor, where getPhoneNumber is defined, and whether getPhoneNumber relies on non-static state that is innaccessible from where it is called by the extension. - -- Peter Davis -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8z8MmNSZCJx7tYycRAjQaAJwPZ1PqA9/TCJO9tD5NMx3vbUXmjgCg2FBb dK5TjUQxzYXZRjHT1XhYhwU= =wB5K -----END PGP SIGNATURE----- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
