Subject migrate IIS to J2ee based web server, then migrate .net architecture to j2ee based one
Date Mon, 06 Dec 2004 20:24:04 GMT
Dear Sir/Madam: 

the company i will work for later on has the software
product based on the .net framework with the IIS
middle ware. because of the requirement of the current
market, the company needs to migrate 
the whole architecture to J2ee based one. 

because the company only has .net resources without
any j2ee experty. my background is with a lot of
java/j2ee and without any .net. at the moment i work
with the chief architecture of this company and try to
figure out how to migrate .net architecture to j2ee
based. if i can help them to map out the .net
architecture to j2ee based one, then i will have the
chance to work on the java/j2ee and probably oracle
migration development work. hopefully i can win this
contract. however, i really need some help/input from
some free resources, like the Forum Groups, to point
me to the right direction.

they plan to start with changing the presentation
layer IIS to j2ee based one. the following are the
list of questions I need to figure out urgently. it
will be very appreciated if you can help on these. 

1. do you think the tomcat web server a good option 
for them or the other ones? 

2. what should be the approach they should apply to 
replace the IIS only at this stage? 

3. how can they replace IIS with tomcat on windows and
keep all the existing binaries? 

4. if the tomcat is a good option, then after 
installing the tomcat, does the apache need to be 
installed as well? if it is, why? 

5. what is the next step for them to migrate the 
architecture to j2ee based one after replace IIS with 

6. do you recommend weblogic or websphere for them at 
this stage? why? 

7. they have the chief architecture knows only the
.net architecture and don't know j2ee one, i know only
the j2ee architecture and don't know .net one. both of
us need to work together to figure out a 
way to migrate from .net to j2ee in a very tight time 
frame. what can you suggest us to achieve this? what 
documentation or books we need for this without 
recruiting additional resource? 

8. if they change the whole .net to j2ee based, what 
else they need to install, except of the tomcat? for
the whole migration, how can they map the 
applications/components from .net to j2ee for this 
migration, like, to jsp(j2ee), iis(.net)
to tomcat(j2ee), (sql server(.net) to oracle(j2ee)

it will be very appreciated if you can help on the 
above as soon as you can. or point me to someone who
can help with this. 

Thanks and regards!
