Dear Ivan,

Thank you for your kind reply and sorry for incomplete information.
Actually I'm using SAAJ for MM7 and the specification as per below :

When the MMS content is delivered, CP differentiates each service using the username and password parameters which also act as an authentication for the CP, therefore, each service must have a unique username. The authentication process is done on HTTP Header , with the following format :

POST /mm7adapter HTTP/1.0
Host: 192.168.31.143:9800
User-Agent: CDMS v.1.0
Authorization: Basic bG9hZHRlc3Q6bG9hZHRlc3Q=

Autorization header is following HTTP Basic authorization, as explained bellow:

Authorization: Basic base64_encode(“username:password”)
MM7 request messages shall be transferred in an HTTP POST request. MM7 responses shall be transferred in an HTTP Response message. The media type “text/xml” shall be used for messages containing only the SOAP envelope. MM7 requests that carry a SOAP attachment shall have a “multipart/related” Content-Type. The SOAP envelope shall be the first part of the MIME message and shall be indicated by the Start parameter of the multipart/related Content-Type. If a SOAP attachment is included it shall be encoded as a MIME part and shall be the second part of the HTTP Post message. The MIME part should have the appropriate content type(s) to identify the payload. Figures below provide few examples of the message structure. This MIME part shall have two MIME headers - Content-Type and Content-ID fields.



already googling for this problem for 2 days and not yet find best solution.
Thank you for any kind help.

Hi all,

is there any way of using template for String in POJO?? I mean this template will act as placeholder and we can change it dinamically.
notice that I'm not talking about JSP here.

Thank you for any information.

Hi all,

I'm learning about EL and trying some code, the code as per below :

Dog.java


DogOwner.java


DogServlet.java


DogLover.jsp


all above code compile perfectly but when I run DogServlet, it turn to DogLover.jsp and gives result as per below:

Dog's name is Spike

Dog owner's name is ${owner.name}

why the EL doesn't work here, I mean why it doesn't replace name of owner?? thank you for any explanation.

Hi all,

I'm just trying code in HFSJ page 346-347 with a little modifications.
my code as per below

Person.java


MyServlet.java


Test.jsp


all above code compiled perfectly but when I run, it throw null pointer exception.
I realized in Person.java, I don't define name variable. Does it the cause of NPE?? but I think it should read the name from MyServlet.java when I call setName method.

What did I miss here? thank you for any reply.

JSP

but what about the c2 reference? isn't that too being getting referenced to null when it is passed as the argument for the go method (to create the reference for c3)?



actually the argument in the go method is not c2 but Copy of the reference of c2.
Since it copy reference, you only make this copy reference to null but you cannot make original version (c2) to be null or refer to another object.
Please see this for better understanding.

Hope this helps.

Hi N Pats,

ok I'll try to explain

Cage<? extends Dog> cg1 = new Cage<Dog>();



Cage <? extends Dog> --> means that you can be assigned a collection that is subtype of Cage and type for<Dog> or anything that extends Dog, so below also correct :

Cage <? extends Dog> cg1 = new Cage <Poddle>(); --> according Poddle is subtype of Dog


In the first case, the type in LHS and RHS is the same. Why is it not the same in the second case? Why can't we write the following
Cage<? extends Dog> cg1 = new Cage<? extends Dog>();



well, the explanation for this is simple you CANNOT use wildcard notation (<?> or <? extends ClassName> or <? super ClassName>) in the object creation so new Cage <? extends Dog>(); --> will generate compile error.

please anyone correct me if I'm wrong. thanks

Hi N path,

one rule you have to remember here that polymorphism is not apply for generic type.
if you provide as per below it will result compile error :

Cage<Animal> cg1 = new Cage<Dog>();

but these example is ok :

Cage <Animal> cg1 = new Cage <Animal>();
Cage<? extends Animal cg1 = new Cage <Dog>();

please check this one for further information
