java.lang.Object
- org.apache.jasper.servlet.JspServletWrapper

```
public class JspServletWrapper
extends java.lang.Object
```
The JSP engine (a.k.a Jasper). The servlet container is responsible for providing a URLClassLoader for the web application context Jasper is being used in. Jasper will try get the Tomcat ServletContext attribute for its ServletContext class loader, if that fails, it uses the parent class loader. In either case, it must be a URLClassLoader.

```
  Sets the compilation exception for this JspServletWrapper.
  
  Parameters:
  
  je - The compilation exception
- setServletClassLastModifiedTime
```
public void setServletClassLastModifiedTime(long lastModified)
```
  Sets the last-modified time of the servlet class file associated with this JspServletWrapper.
  
  Parameters:
  
  lastModified - Last-modified time of servlet class
- getServletClassLastModifiedTime
```
public long getServletClassLastModifiedTime()
