Clarifications for Using Methods

Chapter 7 API Clarifications 73

HttpServlet.service

public void service(ServletRequest req, ServletResponse res) throws

ServletException, java.io.IOException

This method dispatches client requests to the protected service method.

Clarification

Servlets may create additional threads to handle their service logic. However, the

API functions exposed by these objects must be accessed by either the request

handling thread or one of the threads the servlet created, but not by both

simultaneously.

ServletContext.getAttribute

public java.lang.Object getAttribute(java.lang.String name)

Returns the servlet container attribute with the given name, or null if there is no

attribute by that name.

Clarification

To obtain the context class loader (a java.lang.ClassLoader object), use the

com.iplanet.server.http.servlet.classloader attribute. To obtain the

context class loader’s classpath (a

java.lang.String object), use the

com.iplanet.server.http.servlet.classpath attribute.To obtain the context

class loader’s reload interval (a

java.lang.Integer object), use the

com.iplanet.server.http.servlet.reload-interval attribute.

ServletRequest.setAttribute

public void setAttribute(java.lang.String name, java.lang.Object o)

Stores an attribute in this request. Attributes are reset between requests. This

method is most often used in conjunction with

RequestDispatcher.

Clarification

You can set the com.iplanet.server.http.servlet.parameterEncoding

attribute in the request object to allow the

getParameter method to know the

encoding of the parameters it extracts.
