Android programming: Authentication and data exchange with Java EE -

-

i having java application running in tomcat server using spring, hibernate, etc. , 2 web interfaces, 1 implemented in tapestry 5 , other 1 using flex blazeds , spring-blazeds.

in first android application log in server , retrieve data.

i´m wondering how achieve in secure way. first of need know technology best retrieve data server , how can restrict access users have been authenticated.

with read until try implement httpservlet on server , make server calls via http client. in servlet use httpsession check if request comes authenticated user. , data try send serialized (json). unfortunately, i´ve never done things , maybe i´m on wrong way , there more comfortable solutions.

oh yes there many ways communicate server android. method 1 mentioning, every request have servlet or controller intercept request , send appropriate response. every time have add new requirement make controller or servlet , add entry in mapping file etc.

second method use service oriented architecture expose services , android consume services method easy , takes less time implement things.

another way can use sockets. udp or that.

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
