scope="application">
property="firstPage"
value="Current Page Name" />
Collectively, the pages using the counter have been accessed
times.
Listing 13.8 shows the first of three pages that use this approach. The
source code archive at
http://www.coreservlets.com/
contains the other
two nearly identical pages. Figure 13 3 shows a typical result.
Listing 13.7 AccessCountBean.java
package coreservlets;
/** Simple bean to illustrate sharing beans through
* use of the scope attribute of jsp:useBean.
*/
public class AccessCountBean {
private String firstPage;
private int accessCount = 1;
public String getFirstPage() {
return(firstPage);
}
public void setFirstPage(String firstPage) {
this.firstPage = firstPage;
}
public int getAccessCount() {
return(accessCount++);
}
}
