Using variables in a jsp:useBean tag

10-11  Source: Network gathering  Views:2 

I was wondeing if it is possible in any way to use variables in a jsp:useBean tag. Here is an example of what I am trying to do.
String beanType = request.getParameter( "bean" );
if( beanType.equals( "Bean1" ) ) {
beanClass = "com.myCompany.Bean1";
} else {
beanClass = "com.myCompany.Bean2";
<jsp:useBean name="<%= beanType %>" class="<%= beanClass %>"/>
I also tried using this approach
if( beanType.equals( "Bean1" ) ) {
<jsp:useBean id="bean" class="com.myCompany.Bean1"/>
} else if( beanType.equals( "Bean2" ) ) {
<jsp:useBean id="bean" class="com.myCompany.Bean2"/>
Neither approach seems to work. Is there any way around this problem?
