Is it possible to switch the phone to silent mode from a j2me midlet.. If so can some one lead me in the right direction..

There is a syntax error in your query
//statement.execute("insert into ip_table values(address)")

this should be
string query = "insert into ip_table values('" + address + "')";
statement.execute(query);

I am talking about "obj" and not the Object that "obj" points to.

if the Object that obj points to is not thread safe... How can obj be thread safe.. ?? obj is just an handle that refers to the Object on the heap..

hi
i, req and res are thread safe...

i is thread safe because it is declared final.
req and res are thread safe because there is only one object of each for each request... unless the goGet() or doPost() create threads and pass the request and response when creating them.

session objects are not thread safe.. it should be noticed here that a session object is not a local scoped object... the session is captured in the request via cookies.. so the state remains even after the service method completes...
the same can also be said about the servlet context and the Object 'obj' Eventhough the Object 'obj' has method scope.. it refers to a object(attribute) that can be accessed globally...

hi,
Yes dude i think u are right well atleast thats what the HFS book says....
"if there were not <http-method> elements in the <web-resource-collection>, it would mean that NO HTTP methods are allowed by anyone in any role...".. well i too have the same interpretation as u \

hi,

have a question on web-app security...
when having more than one <security-constraint> elements in the DD with conflicts... the HFS book describes how the various conflicts can be resolved...
here is the DD..

<web-app>

<security-constraint>
<web-resource-collection>
<web-resource-name>Something</web-resource-name>
<url-pattern>/me/Display/*</url-pattern>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint/>
</security-constraint>

<security-constraint>
<web-resource-collection>
<web-resource-name>Something</web-resource-name>
<url-pattern>/me/Display/*</url-pattern>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint> ///this or is this tag is not included at all...
<role-name>*</role-name>
</auth-constraint>
</security-constraint>

the book discusses all combinations except this one ... one that allows all roles to request and one that allows none to access... though the DD may not make sense nevertheless it is one valid combination...
The HFS book says that an empty <auth-constraint/> has the final word but the next line says that --- "If one of the <security-constraint> elements has not <auth-constraint> element then it combines with anything else to allow access to all"...
so does the abv combination allow access to all roles or does it prevent access to all....

Simon

hi,
the output would be option a followed by option b
the reason is that before a subclass object is created its super class instance is initiated first (its like every sublass object has a super class object inside it)

hi,
u can communicate with other java programs using sockets or RMI..
Regards
Simon

thats what i am trying to say... the wrapper classes have overriden the .equals() and the hashcode() method and may have used the instance of operator to check for the class type..... since wrappers are primitives wrapped in objects.. just think of it ... can two objects of two different classes be same.. its the same argument here...
hope this helps
