Hello Filip,
I have been trying to use your session replication libs in tomcat 4.1 and have run
into problems. I was wondering if you could help me out here. I am trying the
replication with a simple jsp page on a one box setup with two instances of tomcat
running.
The jsp page simply prints out the session id and the cookies it has received. Here is
the text of the JSP page:
<%@ page import="javax.servlet.http.*" %>
<HTML>
<BODY>
Server: ONE
<p/>
<%
if (request.getSession().isNew())
{
%>
This is a new session.
<%
}
else
{
%>
This is an old session.
<%
}
%>
<p/>
The session id : <%=request.getSession().getId()%>
<b>Cookies:</b><br/>
<%
Cookie[] cookies = request.getCookies();
if (cookies != null)
{
for (int i=0; i < cookies.length; i++)
{
%>
<b>Domain:</b><br/>
<%=cookies[i].getDomain()%><br/>
<b>Name:</b><br/>
<%=cookies[i].getName()%><br/>
<b>Value:</b><br/>
<%=cookies[i].getValue()%><br/>
<b>Path:</b><br/>
<%=cookies[i].getPath()%><br/>
<b>MaxAge:</b><br/>
<%=cookies[i].getMaxAge()%><br/>
<%
}
}
%>
</BODY>
</HTML>
The pages in the two instances are exactly the same except that one says SERVER ONE
and the other SERVER TWO so that I can distinguish between the two. I believe I have
setup the Context properly for both the instances.
I am using Apache to do the round robin scheduling using mod_jk.
When I hit the page and look at the message in the two tomcat consoles I get the
following:
first console:
[InMemoryReplicationManager] Replicated Session created at org.apache.catalina.c

second console:

It seems like the first box created the session and it was replicated properly in the
second box.
Now when I reload the page and the request goes to the second box I would expect the
same session id to be printed out. Instead I get the following output from the jsp
page:
Server: TWO
This is a new session.
The session id : E086477BF76F98820020F3FA7048C5E8 Cookies:
Domain:
null
Name:
JSESSIONID
Value:
6B5CF3C232D4D8636D14586083E0B094
Path:
null
MaxAge:
-1
The second server did receive the right JSESSIONID (6B5CF3C232D4D8636D14586083E0B094)
but decided to create a new session instead of the replicated one.
Do you have any ideas as to why this occur?
thanks
Sanjeev
