SessionSynchronization ?? is HJEJB Wrong or i am lost......

May be before giving the bean the beanness(may be before setting the session context) the container might look into the descriptor file to look what are the necessary services to be provided(if cmt provide transaction support,what type of bean it is etc)so If the container finds its of type stateless then it might do the interface check

EJB Certification (OCEEJBD)

HFEJB - Doubt regarding mock xxam question 6 on page 245

1)I think you cannot define a create exception in the remote interface
(home interface)
2)You cannot return the bean itself but an ejbobject which represents the bean
3) For a stateful session bean there can be any number of create methods with different parameters which will be represented by a EJBCreate in the bean

Configuring tomcat to host a website

I have recently registered a domain name with 1&1.
They have provided me with their name server and I have given them my ip address(provided by my ISP)
Now I want to host my website.Now for testing I want to use my local machine as a server so I installed tomcat5.5 on my machine.
I have created a web application called xxx in the webapps folder.
How can I configure tomcat to view my web pages. I changed the host name in server.xml but that did not work out.

Thank you in advance

redirecturl (from servlet)

Hi ,
I need to send a redirect url from my servlet to a cgi app which takes the url and redirects it to the corresponding app.Can I do something like this
and can the client take it as a url string.Thanx
I am using something like
buffer.append("SomeServlet");
buffer.append("JSESSIONID=");
buffer.append(sessionValue);
buffer.append("?");
buffer.append(req.getAttribute("remoteURLExpirationID").toString());
buffer.append("=");
buffer.append(System.currentTimeMillis());

Servlets

sendRedirect(singlesignon)

I will be getting a request from a secured site like https://www.x.com?id=12&value=1234.
I have written a servlet to map the keys id and value to different values
and formed a query string like id1=12&value1=1234.
Then I have to post the data to another servlet which accepts this id1 and value1.I have done it using sendRedirect.This servlet does the client verification etc and calls another servlet which creates a session and my servlet has to recieve the session ID and pass it back to the client(Single signon)
My quetion is
1)Is it safe to use sendRedirect and is there any other way to post the data to that servlet.
2)How will make my servlet receive the session Id.Do the servlet which handles the session has to post the session Id back to me.
Thanx

Problem starting weblogic server 8.1

Hi,
I have the following problem when starting weblogic server 8.1(http://localhost:7001/).But when I type (http://localhost:7001/console/)its working fine.
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
