RE: email within action
Sending email involves a lot of processing If I was you then I would rather use JMS to send emails (so that you can send email asynchronously)... Your action send a message to a JMS server to send email with details and then that's it... The MDB bean will scan the queue and then send the email one by one ...

email within action
Hello Is it possible to send an email within an action? How/What are the issues? Is this scalable? How does it play with the framework and multiple simultaneous clients? Any insight would be appreciated.
Re: email within action
yes, The main issue will response times if you a send emails synchronously ( if you can you send async). Async will definitely scale better since the client isn't blocking a thread for nothing. Simultaneous clients should be no problem as long as you follow the same threading rules as everything else shared vars etc. For high loads you should use messaging. There's a ton of stuff on the net about async programming but it really depends on your environment. For a full JEE setup I'd probably use a Message Driven Bean. What sort of volume are you looking at and what's the environment? Oz On 25/06/2007, at 9:35 PM, Chris Pat wrote: Hello Is it possible to send an email within an action? How/What are the issues?

Well you will probably not be doing the emailing async but rather firing off an async request to send an email ( eg send hello world to this list of 1000 recipients) and response to the client (ie browser) that the emails are going out. You really don't have to wait for an email to be sent since email is a store and forward mechanism anyway with no guaranteed delivery. You probably need to read up a little on messaging. As Guru also said a JMS server would meet your needs. There's generally a JMS server built into most app servers or you can plug one in if it doesn't have one.

RE: email within action
Nope that is not possible with JMS ... you may wish to use web services have a look at axis2 from apache RMI / WEBSERVICES are synchronous while JMS is not Regards Guru -Original Message- From: Chris Pat [mailto:[EMAIL PROTECTED] Sent: 25 June 2007 14:30 To: Struts Users Mailing List Subject: Re: email within action Hi Thank you.

Re: email within action
Depends on what you want to do really. As Guru points out you can use Web Services though that can grow unwieldy. For something light and pretty straightforward you may just want to use JSON (javascript object notation) or Xml HttpRequests. Have a look at the showcase project in S2 on how to use the Dojo toolkit. Oz On 25/06/2007, at 11:29 PM, Chris Pat wrote: Hi Thank you.
