Dear All,
We are running more than 20 applications in shared environment (Same H/W
+ Linux + JDK1.4_2 + Apache + Tomcat/4.1.29-LE-jdk14 + Struts).
Questions 1) Is there any document or guidelines for migrating of web
applications using JDK1.4_2 to JDK1.5. I am searching Java sdn and Java
platform migration guide, but they are not really very useful related to
web application.
Couple of things I came across, Old code with enum as variable should be
refactored with different name and Comparable Interface in JDK1.5 is not
compatible with JDK1.4_2 because of Generic. Also assumed that we need
to change to exact type wherever we used java.lang.Object as variable
type. (Is Generics causing all the trouble, Generics going to be our
nightmare).
I am expecting some more guidelines like above (if possible migration
approach), Some of the open source project should have some guidelines,
but I am not able to grep it. Please help me by sending the appropriate
links.
-----------
Questions 2) Is there anything I should carefully consider to migrate
from Tomcat/4.1.29-LE-jdk14 to Tomcat_5.5.20?
-----------
Questions 3) Will I get any performance gain by the above migration?
Regards,
Mohan
