RE: Storing the Output of a Servlet to Database

[Rajesh P]

Thanks Craig, for the input. I was able to capture the output using servlet filter and 
the response wrapper classes.

In a Servlet 2.3 environment, you can easily create a Filter that wraps
the response and copies the output into a buffer to write to your
database, as well as sends it back on to the client.  There have been
articles written describing this sort of thing that a Google search ought
to find for you.

RE: Storing the Output of a Servlet to Database

[Rajesh P]

Hi,
I am aware of how to store the contents to the database. What i am really interested 
is how to capture the output of the servlet. Forget PDF, assume that the Servlet is 
just serving a normal html content. After the servlet has given this to the response, 
how to capture this as a byte stream is my real question.
Thanks,
Rajesh

Ideally, you should store the document on file system, the better place for
PDF BUT you may some weird requirement
Anyway, if you are adamant on doing this.

--first way--

0. create a field in your database with blob data type. (I have MySQL) but
oracle/ mssql7 all have this data type.
1. generated pdf document needs to converted into binary data. ( it is be
default ;-)
2. write it down to that field as normal query.

you may wish to see java.sql.Blob and java.sql.prepraedStatement.setBlob

--second way--
0. create a field in your database with varbinary type.
1. generated pdf document. read it as byte stream and get arrys of bytes.
2. write it down to that field as normal query.

see java.sql.prepraedStatement.setBytes

RE: Storing the Output of a Servlet to Database

[Rajesh P]

Hi,
The option 2 is what i am looking at. The API for generating the PDF writes to the 
servlet outputstream directly. So for the time being forget PDF, say, I need to 
capture the output of any servlet, say a html content, and store that to a db or file, 
how do I do that?
Thanks for the response.

Hi
There are various ways u can do this.

approach 1:
simple and best approach.. create a PDF file in the weblocaiton and compose 
the path and store it. when ever u want u can make use of it.

appraoch 2
Create a CLob column once the PDF is generated push to a DA method before 
giving it to Servlet.

apprach 3
Create a BFIle useit.

Hi,

I've had a similar problem - and there really doen not seem to be any 
"good" solution. You might try it with a scriptlet - something like
<%
String price = .getPrice();
%>
then you can call your custom tag with:


That's certainly not nice but it'll work.

Hope that helps,

Need a Design pattern suggestion

[Rajesh P]

Hi,
Have a small problem on deciding the approach. 
We have a datasource which is a C++ server that returns data in the form
of a byte array ranging from 8000 to 32000 bytes of data. There would be
many chunks of such byte arrays.
FYI, we are using the Struts framework.

Requirement:
1) To be able to parse this byte array according to a predefined format
and display it in the JSP in the form of a table.
2) To be able to sort on the displayed columns of the table.
3) The transaction involves navigation across multiple screens. 
For ex, 
a) in the first screen I would be displaying the Customer Number and
Name along with a list of Orders in the form of a table.
b) Clicking on one of the orders takes to the second screen
c) In the second screen, it is required to display the Customer number,
name, selected order details as header and a list of line items
associated with the order (in the table format).
So now when we navigate to the second screen, the Customer number, name
and selected order details should be got from the byte array fetched and
only the line items should be taken from the C++ datasource. So there
should be a mechanism to retrieve any data from the byte array based on
a key value.

We have thought of the following approaches.
1) Create objects which would hold each record of the byte array. In
such a case, the disadvantage would be the number of objects which are
created that would hit the performance. Advantage would be that a
collection sort on the object would simplify the sorting process.
2) Have the byte array as it is and parse on it each time it is
required. In this case, a sorting of the records would be dicey.

Can you kindly suggest a mechanism which would be best suited to satisfy
the performance as well.

Thanks in advance,
Regards
Rajesh
