Hello,

How are you handling the Travel Agent login? The Use Case Diagram shows that the travel agent has to login. Is the method of login different from that of the customer? Should we add a new use case for the Travel Agent to view all of the customers and select one to book a flight for?

Thanks.
Hello all,

Which version of J2EE specification should we use? The current one is J2EE 1.4.

thanks.
Hi Mark,

Thank you for clearing that up. I don't want to be too persistant in my questions, but i thought it may help others to see the distinction you found. Thanks, I appreciate your find.

Here is how it may help:
Although a design should be implementation nonspecific, I have found with EJB that an exception must be made. If I am using EJB 2.0, I will use more data objects as cmp entity beans instead of DAO. If I'm using EJB1.*, then I may not have any entity beans. This change would show up in the class diagram and sequence diagram.

Also, I have read the discussions about whether to indicate EJB classes in the class diagram. Since this project is a mandatory J2EE project, then I think it is ok and appropriate to mention indicate the presence of EJB classes in the class diagram.

Thanks again, Mark for pointing out the EJB version.

Thanks, Rajah! This is helpful. Although the details seem unimportant, it may make a difference in the componenent design. Thanks for the help.

Hi Solomon,

Having changed my mind back and forth on this several times in the last month, I decided to stick with Container Managed Security(CMS) finally.


How are you using CMS in the Swing application?

Thanks.

Congratulations, Deepak!

Thanks for the great contribution to this group!

I have a few questions. I hope you don't mind answering them.

1) is the expected standard EJB 1.1 ?
2) is the transaction id in the rpc-xml calculated by FlyByNight?

Thanks.

-Ravi
Hello,

Is the transaction identifier found in the XML-RPC request created by FlyByNight? If so, is it unique only within each credit card type?

Anyone?

Thank you.

Manju,

Sorry to respond late to the emails. I hope you can answer my question:

I thought ssl worked by using a symetric key to encrypt message body. You stated that the message body would not be encrypted. Could you explain this?

Thanks in advance. -Ravi
I have some questions regarding the contents of the XML-RPC request to TransMaster.

1) Where is the credit card type (i.e. Mastercard, etc.) listed?
2) Does the merchant id refer to FlyByNight?
3) Is the transaction identifier created by FlyByNight? If so, is it unique only within each credit card type?

Thanks in advance for your help.

BTW, I read in another topic that the XML-RPC message is not encrypted via https. The base64 encryption is a very weak type of encryption. Is it enough to use SSL, or should the message body also be encrypted?

Thanks for reading. Please respond.

Mark,

I don't know if I made it clear. My question is how did you know to use EJB 1.1? Where did you read it?

Thanks in advance.

-Ravi
Mark,

#For sending Email can i use message driven bean
yes, you can. You also can use other J2EE things like a session bean. But be careful, the expected standard is EJB 1.1.



Thanks for pointing this out! Where did you read this?

Thank you again. It makes a real difference when designing the class diagrams.

Goutam,

When using HttpConnection open/close, are you using JSSE to encrypt the data? If not, then how will the data be encrypted?

Thank you.
