I apologize for the basic question, but could someone please tell me what is meant by:

"in JTA environment, use of process level read-write cache is not recommended"

I am currently developing a web-based application using Tomcat, Struts and MySQL. I am planning to use ehcache with read-write caching strategy. Is it safe to do so? I can't use read-write strategy, since I have to modify some of the records during runtime. Is there any other alternative that allow me to do both read & write safely (if that warning message above applies to me, of course). I have tried JBossTransaction caching strategy without success..


Again, I apologize for the basic question. I've tried to look in google, but could not find the answer to my question.



Thank you very much for your kind helps!

Is Tomcat a JTA environment?

Hello Gavin,

Now that you mentioned Tomcat, I remember that I read sometime ago, about the limited support in Tomcat.
And if my memory serves me correctly, it also says that Tomcat is unmanaged (maybe wrong term). So I presume it also means that it is not a JTA environment, and hence I can use read-write caching strategy?


Thanks a lot for the help!

Alex.

Exactly. Tomcat is not an application server.
