What is the best practice for developing web service?

Hi All,
I'm a newbee to web services...
I was wondering what would be the best approach in developing a web service,
using tools or programmatic approach?
If I use WebLogic Workshop, am I tied to a vendor?
Is it possible for me to develop web services using workshop and deploy in
another app server..?
I would appreciate if somebody could give me a pointer to start.
I have already referred BEA's docs.
I'm still confused on a good starting point on the best approach to develop
protable web services.
Thanks in advance for any inputs.

K K-
You have a very valid point on the simplify or complicate matters. If you are
going for clean and not-so-time-centric code, then there are several different
programs and packages out there you can choose from.
Since you are specialized in J2EE, than the Sun package may be what you are looking
for. BEA's classes simplify much of the work you will be doing, but you could
emulate their classes or extend yours above the functions provided in theirs.
It all boils down to how much work are you willing to do.
If you are asking for more detailed, coding 'Design Patterns' to utilize, I would
wait for a few more posts from other folks as my work often requires me to utilize
the tools provided.

Eric,
Thanks for the response.
I was also looking at Sun's WSDP 1.1, which is more programmatic approach.
Some how, I feel being a J2EE developer, I should go on the direction
of the
programmatic approach.
Using the tools could simplify or complicate things. Also, the Workshop
samples import all weblogic specific packages.
My code looks so dirty with many vendor specific packages being imported.
Could you give me your suggestions for a clean and neat approach?
I would personally prefer to avoid the quick and dirty approach.
Thanks again.

The best approach in developing portable web services is knowing whatyou
are
planning on using them for as well as how much is willing to be spent,etc.
BEA's Workshop is portable to other frameworks, but the ease ofintegrating a
developed client or a developed server can very greatly. Even moreof an
issue
is migration from one framework to another. If you choose to developin
Workshop
and your company later deploys .Net solutions, some of your work mayhave
to be
redone unless the company is willing to keep portions of the 'old'system
around
until new versions of the service are available. However, Workshophas
several
ant tools available that would assist you in deploying to other appservers or
even a stand-alone application should you need cross framework abilities.
If you are just starting out in web services, http://www.webservices.org
is a
good place to start checking out vendors in the space.

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

What is the best practice for AppleScript deployment on several machines?

Hi,
I am developing some AppleScripts for my colleagues at work and I don't want to visit each of them to deploy my AppleScript on their Macs.
So, what is the best practice for AppleScript deployment on several machines?
Is there an installer created by the Automator available?
I would like to have something like an App to run which puts all my AppleScript relevant files into the right place onto a destination Mac.
Thanks in advance.
Regards,

There's really no 'right place' to put applescripts. folder action scripts nees to go in ~/Library/Scripts/Folder Action Scripts (or /Library/Scripts/Folder Action Scripts), anything you want to appear in the script menu needs to go in ~/Library/Scripts (or /Library/Scripts), script applications should probably go in the Applications folder, but otherwise scripts can be placed anywhere. conventional places to put them are in ~/Library/Scripts or in a subfolder of ~/Library/Application Support if they are run by an application. The more important issue is to make sure you generalize the scripts: use the path to command to get local paths rather than hard-coding them in, make sure you test to make sure applications or unic executables you call are present ont he machine, use script bundles rather tna scripts if you scripts have private resources.
You can write a quick installer script if you want to make sure scripts go where you want them. Skeleton verion looks like this:
set scriptsFolder to path to scripts folder from user domain
set scriptsToExport to path to resource "xxx.scpt" in directory "yyy"
tell application "Finder"
duplicate scriptsToExport to scriptsFolder with replacing
end tell
say "Scripts are installed"
save this as a script application, then open the application pacckage and create a folder called "yyy" in the resources folder and copy your script "xxx.scpt" into it. other people can run the app to install the script.

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you

Eduardo

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

What is the best practice for using the Calendar control with the Dispatcher?

It seems as if the Dispatcher is restricting access to the Query Builder (/bin/querybuilder.json) as a best practice regarding security. However, the Calendar relies on this endpoint to build the events for the calendar. On Author / Publish this works fine but once we place the Dispatcher in front, the Calendar no longer works. We've noticed the same behavior on the Geometrixx site.

What are the best practices for generating an EPS logo from InDesign?

Our costomer is running into technical issues with the logo we sent them, which was exported from Indesign. Images were not embedded and fonts missing. I was able to embed the images and fonts. However, we DO NOT want them to be able to make any text changes. So after exporting an eps, I opened the file in Adobe Illustrator and made all the text outlines. I hope this works. But I just wanted to post the question on what are the best practices for doing this?
The client needs the logo with transparent background, images emebdded and type in outlines. Also, they need some space around the text. When I exported the eps, the file is right up on the edge of the type.

It sounds like you are pretty far from "best practice" with regard to logo design and delivery.
These days, the very use of the EPS format should be considered bad practice, and some other terms in your post, (i.e., 'images,' 'missing fonts'), make it sound like there is not a seasoned logo designer involved.
That said, you probably already got the advice you need to get out of the immediate jam. However, without proper logo design, you and the client will soon be facing other problems. You should be delivering a 100% vector graphic in single-color (black) and corporate-color(s) versions, with no live font data, that has been test-scaled to very small and very large sizes; ensuring it will work at postage-stamp size and on the side of a truck or building, with specific spot color(s) and proportions that will enable it to be offset printed, embroidered and screen-printed on apparel, and cut into signage materials and decals.

What are the best practice for CQ5.5 configuration?

Hello,
What are the best practice for CQ5.5 configuration which handle for High availability.
Last time I had a issues on server when I was uploaded 2 GB of DAM and then after that the server is not able to start and always getting error regarding Tar Persistance.
So kindly request you to please let me know what are the best apache felix configuration.
Thanks in advance...
Regards,
Satish

Hi,
A DAM upload, regardless of the size of the assets, never should result in TarPM problems, unless you run into an OOM, which left the repository in an unclean state. So if you regularly do DAM uploads of that size, you should check the Garbage Collection logs and probably adjust the heapsize if necessary. You might want to limit the number of concurrent running workflows to keep the memory consumption a bit lower.
To your question: HA in a traditional sense you cannot achieve with a single box, even with optimized settings. In an author usecase you would need clustering.

What is the best practice for creating master pages and styles with translated text?

I format translated text all the time for my company. I want to create a set of master pages and styles for each language and then import those styles into future translated documents. That way, the formatting can be done quickly and easily.
What are the best practices for doing this? As a company this has been tried in the past, but without success. I'd like to know what other people are doing in this regard.
Thank you!

I create a master template that is usually void of content, with the exception I define as many of the paragraph styles I believe can/will be used with examples of their use in the body of the document--a style guide for that client. When beginning a new document for that client, I import those styles from the paragraph styles panel.
Exception to this is when in a rush I begin documentation first, then begin new work. Then in the new work, I still pull in those defined paragraph and or object styles via their panels into the new work.
There are times I need new styles. If they have broader applicability than a one-off instance or publication, then I open the style template for that client and import that style(s) from the publication containing the new style(s) and create example paragraphs and usage instructions.
Take care, Mike
