Resin simplifies creating Java classes by automatically recompiling and reloading the Java when the source changes. TestBean.java to TestBean.class. So programming JSP beans just involves editing Java code and pressing the browser's reload button. Load Balancing Load balancing increases performance and reliability. So each static web server, like Apache, may be underused and can support multiple Java processes.
Load balancing lets sites scale by adding new servers as demand increases.
Load balancing increases reliability. Load balancing increases reliability because Resin will automatically try another Java server if one fails.

With XSL, you can change the entire look of a site by changing the stylesheet, without modifing individual pages. In addition, the JSP and Servlet pages become simpler and easier to understand.
