I reaaly want to the implication of calling static members of a class with an instance of such class. For example, Calendar now=Calendar.getInstance(); now.setTimeInMilis(someLongValue); now.MONTH; it gave some incorrect value but i want to know why?

Rob Prime, I don't know that it is an offense Posting what I felt will assist Matthew McHale if not solve his situation.
I felt we are all here to help each other, Matthew McHale has almost the same problem as I do.
In my case, I have already gotten some solutions which I felt will help Matthew McHale if not solving his own problem totally.

I post my Apologies.......................

You may also Need a mail server like Apache James Mail Server if you don't have steady internet connect for your learning.
But JavaMail API and Java Activation Framework are inevitable.

Good Luck

Actually, I don,t mean configuring my GMail non Yahoo account.

This is my situation,

I have Apache James Mail Server installed on my Local Machine. I also have internet connection which I use to try my code for communication between my local mail server and remote servers like GMail and Yahoo.

So far, things works fine on my local server but I issues arises when I tried access to a remote server like GMail/Yahoo with the code in my previous post and got


Now, I observed that I don't need uncomment either lines 5 or 6 in order to send mail to remote server.
Sending mail with either line 13 or 14, the message sends successfully with out any error.
BUT, unfortunately the message never get delivered to the Yahoo/Gmail Account.

Please Your Help will be high apreciated. I have researched alot for a solution without success.

I am sure that the HttpServletRequest have some methods retrieve the URL and the URI from a particular request object.

But if you talk about the second servlet, then you MUST know the port where it was deployed.

DNS server could have being the solution, to resolve this inconsistency/change in the address (port no).

But since it seems there is no DNS server to resolve this, your have no alternative than to create a mechanism to conform that
the URI is valid before processing a request.

A change in this port no is as good as saying the http://www.yahoo.com was changed to http://www.yahoo.org.
I dont see any alternative to this...

Will equally appreciate any other person will have a better idea

Depending on the need, I think it will be clever to have some hidden text field then make assign the Javascript variable as the value for your hidden field which could be assessed later by the JSP/Servlets.

Welcom to Java,
You have to define the port of your choice having in mind that;

Port numbers in TCP/IP systems are 16-bit numbers and the values range
from 0–65535.
In practice, port numbers below 1024 are reserved for
predefined services, and you should not use them unless communicating
with one of those services (such as telnet, Simple Mail Transport
Protocol [SMTP] mail, ftp, and so on).

Client port numbers are allocated
by the host OS to something not in use, while server port numbers are
specified by the programmer, and are used to identify a particular service.

Note that for you to establish a communication,
Both client and server must agree in advance on which port to use. If the
port numbers used by the two parts of the system do not agree,
communication does not occur.

It is not just like that, you will need to <c:if ... to test and control the condition you need.

Break out of, when your condition if meant.>

Using relative is far easier,

If only you know you context root (mostly the URL that does not specify any particular page)
eg http://localhost:8080/yourApplication/. Here "yourApplication" is the context root.

All you need to do is reference all other pages assuming that the context root is your working directory.

eg if you want to reference http://localhost:8080/yourApplication/forms/registrationForm.jsp, you can do it this way
forms/registrationForm.jsp
