SV: [Xdoclet-user] xPetStore v2.1 released

Title: RE: [Xdoclet-user] xPetStore v2.1 released

I haven't seen the example code in question, but there is a significant difference between a plain java object and a session bean. The plain object has to be stored fully in the http session. The session bean could be stored somwhere in a cluster environment whitch could handle load balansing and probably persistence. ( If the shopping cart contains much information the memory requirement could be crutial. I've heard a lot of warnings about storing this kind of information in the session object, but then again I've also heard general warnings about using statefull session beans at all because of memory requirements :) I don't now if this is still the case.   Oystein -----Opprinnelig melding----- Fra: Brian McSweeney [mailto:[EMAIL PROTECTED]] Sendt: 7. januar 2003 14:40 Til: [EMAIL PROTECTED] Emne: Re: [Xdoclet-user] xPetStore v2.1 released Hmm, this gets to the root of my question. All the educational material seems to show a shopping cart as the perfect use for a stateful session bean. However, if it's just put in the HttpSession object in the web tier anyway, could someone please tell me what is the purpose/advantage of using a stateful session bean?   Someone at work suggested that it might be used to handle sessions between a java app client and server. Is this valid? thanks, Brian   ----- Original Message ----- From: Herve Tchepannou To: xdoclet Sent: Monday, January 06, 2003 10:37 PM Subject: RE: [Xdoclet-user] xPetStore v2.1 released Honestly, in real-world app, I would have used plain Java Object stored in HttpSession instead of SFSB. This was used more for educational purpose :-) -----Original Message----- From: Brian McSweeney [mailto:[EMAIL PROTECTED]] Sent: 06 January 2003 09:11 To: Herve Tchepannou; xdoclet Subject: Re: [Xdoclet-user] xPetStore v2.1 released Hi all, excellent project Herve. I have a real basic question to do with ejbs though. You use a stateful session bean for the shopping cart implementation. When the struts actions use the shopping cart they store it in the HttpSession object. The thing I don't understand is, how does a stateful session bean offer you more than just a plain java object? If it is just being stored in the HttpSession object anyway, what extra does it offer you? Hope this isn't too off the xdoclet topic. thanks very much Brian ----- Original Message ----- From: "Herve Tchepannou" <[EMAIL PROTECTED]> To: "xdoclet" <[EMAIL PROTECTED]>; "jboss" <[EMAIL PROTECTED]> Sent: Sunday, January 05, 2003 7:17 AM Subject: [Xdoclet-user] xPetStore v2.1 released > I'm Proud to annouce a new release of xPetStore v2.1 > > xPetStore is a WODRA (Write Once, Deploy and Run Anyware) implementation > of Sun > PetStore application based on the following opensource tools/frameworks: > - xDoclet > - Struts > - Sitemesh > > xPetStore has been successfully deployed and tested on the following > application servers: > - JBoss > - WebLogic > > You can download the lattest version of xPetStore at > http://sourceforge.net/projects/xpetstore > > ----------- > This release has the following changes: > - Integration with JUnitEE > - Simplify the installation process highly simplify > - Spilt build.xml to reduce the complexity of the build process > - Mailing list created at sourceforge net > - Bug fixes > -- > > Herve Tchepannou > mailto:[EMAIL PROTECTED] > > > > ------------------------------------------------------- > This sf.net email is sponsored by:ThinkGeek > Welcome to geek heaven. > http://thinkgeek.com/sf > _______________________________________________ > Xdoclet-user mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/xdoclet-user > ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Xdoclet-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/xdoclet-user
