JSP - MVC coding standards

It seems that the world of server-side MVC application development is getting quite fuzzy as to what technologies to utilize.
For examples
- EL once was in JSF now it is in JSP 2.0.
- JSF has custom tags that overlap with JSTL
- JSF seems to do what Struts does
- How about JDO verses EJBs
etc....
So more specifically
1. Is JSF a replacement for Struts? If NOT, what does Struts do that JSF does not? Do Ineed both?
2. Is JDO a viable replacement for EJBs?
3. When is JSTL needed if I am using JSF?
4. Are any/all of these acceptable technologies for deploying production applications?
We are trying to develop some sort of development standards but I do not know how to get around all this confusion.
HELP......

By SWITCH, and you alluded to this, if it were a NEW
project, is there enough in JSF, JSTL etc... that
Struts would no longer be necessary?As for JSTL, no, it's not nearly sufficient to use alone in JSP pages for my project. But JSTL doesn't, from what I've seen, provide an alternative to Struts. I do use the Struts taglibs as much as possible. Also, much of my code could probably be written into custom tag libraries, but as I am the primary developer for most of it, and the schedule has been fairly tight, I don't have time to go thru the process of writing tag libraries. As you might guess, there are some nightmare pages regarding scriptlets, but I live with it. I've been doing JSP since it came out, almost, and for me I don't care. I've been doing HTML since 1995, so I'm pretty familiar with it all. I don't care about the taglibs make it easier for HTML/graphics people. I ame the HTML/graphics person and the Java programmer and all that in one.
Also, JSF, from my understanding, doesn't provide a complete alternative to Struts. From what I know (and correct me if I missed something), JSF only provides a view part of MVC as layer on top of JSP, not the model or controller sides. So JSF should work with Struts just fine, and it might simplify some areas of my project, as might more JSTL. But there are some complicated GUI things being done in several of my project's pages, and as I mentioned about time....
You have to look at the project requirements and the technologies and compare capabilities vs. needs.

What are the best coding standards for ADF 11g?

Hi,
Do we have any link that will suggest the best coding standard practices used for ADF 11g?
I am looking out from the perspective of some standards that can be defined before starting my project to know the team on how to
1. Minimize Duplicity and max reusability of code
2. Package the code
3. Resource bundle usage and its calls
4. Maintainning format consistency eg. date display format, number format
5. Exception handling
6. Logging
7. Namiing conventions
Also then we might have standards on
1. Task flow dev.
2. EO and VO creation standards
3. UI development standards [purely ADF component based]
Thanks in advance

XQuery Coding Standards

Are there any XQuery coding standards defined for use in OSM?
Or does Oracle provide any such standards for naming conventions, variable names, the case-sensitivity etc?
Or are the standards similar to what we follow for Java?
Please help.
Thanks in advance!

OSM does not dictate a specific set of coding guidelines for XQuery, just as it does not for Java. Normally coding guidelines (whether for Java, XQuery or other technologies) would be defined for a given project based on the best practices and experiences of the System Integrator or Service Provider that is implementing OSM.
Given that XQuery is an industry standard language, we would encourage you to follow best practices established in the industry.
Generally, for XQuery code that the OSM product team writes we follow Java style naming conventions and style wherever applicable. This is a convention we find reasonable given our team routinely writes and reviews both XQuery and Java code so having the same naming convention makes sense.
If there are are additional more specific questions you have on this topic feel free to ask them and we'll do our best to help you.

R12.2.0 online pathcing coding standard - table alias name = shcema name

We are getting coding standard violation error for particular file saying schema name is hard coded in the file. But actually we didn't use any table name with schema name.
For ex.
select xle.event_id from xla_events xle;
Here the table xla_event doesn't use any schema name, but the "XLE" is a schema name in database. Because of this we are getting code standard violation error.
This shouldn't be a coding violation.

Please post the details of the application release, database version and OS.

Peer reviews,coding standards and audit norms

hi,
what is meant by peer reviews, coding standards and audit norms in development project of ABAP.
regds:
balakrishna.

Hi Bala,
Peer review: The code which is written by the developer will be cross checked by one of the team member if the code fulfills the technical spec or not.
Coding Standards: In a project the client and the software service provider will have an understanding regarding naming convention of all variables, constants, internal table, select-options, etc.
Example: if it is a select-options the field should be named with the first letter S_ then you will write S_Matnr, and for variables you have to follow V_ then V_maktx.
Audit norms: Audit norms will depend on the organization so it does not have any standard answer.

Lakshmikanth

[SAP Note 783224 - Rollback of the note 429073|https://service.sap.com/sap/support/notes/783224] is high priority...
Important:

Implementation of Oracle Coding Standards and Code Quality Checks

I wanted to implement a list of coding standards and code quality checks for my oracle packages,functions,views,tableetc .
for example
All variables with number datatype should start with N_ and charcter type with C_ in all my tables & views definition.
This can be identified during peer review & can be corrected, but i think this is a repeated process which i don want to burden the developers rather i wanted a tool which does all these kind of checks which can be automated.
Is there any tool which does this operation or can someone give me a little idea how can i automate these stuffs bu creating a generic oracle procedure which can run through all the tables,views and generate a error report for those which are deviating from the standards.
Thus we can reduce the manual effort spent on peer review, please suggest.
thanks in advance

+"Encoding the type of a function into the name (so-called Hungarian notation) is brain damaged—the compiler knows the types anyway and can check those, and it only confuses the programmer."+
Linus Torvalds
+"No I don't recommend 'Hungarian'. I regard 'Hungarian' (embedding an abbreviated version of a type in a variable name) a technique that can be useful in untyped languages, but is completely unsuitable for a language that supports generic programming and object-oriented programming—both of which emphasize selection of operations based on the type an arguments (known to the language or to the run-time support). In this case, 'building the type of an object into names' simply complicates and minimizes abstraction."+
Bjarne Stroustrup
2) Conditional Statements
IF (x = 1) --> Wrong
IF ((x = 1) AND (y = 2)) --> wrong
IF x = 1 AND y = 2 --> RightIdiotic rules. The simple rule should be readability of code. Not how many brackets to use, and when not to use brackets. Minute standards like detracts from designing and writing proper code, fast and efficiently.
There are many more rules (which is specific to ur application) which can be incorporated in the tool, there by giving consistency ,readability and easy to maintain for the developers.Bull. The more rules there are, the more difficult it becomes for programmers to write code. As it is no longer about writing readable and flexible and performing code - it is about double checking every single statement line against a huge list of rules about do's and dont's. It is not about getting the programmer focusing on solving the problem - it is about distracting the programmer with a complex and large rule list of how the code should look like.
Sorry - but this rubs me the wrong way. In that environment, I would be the first to tell you to shove your "+many more rules+".
I've developed systems in over a dozen languages over the years. I've seen all kinds of standards. The standards that work are those that are short, simple and sensible. Hungarian notation is not sensible. Writing reserved words in uppercase is not sensible. Dictating how brackets should be used is not sensible.
What is sensible is using the de facto naming standards in use today - as per .Net Guidelines for Names (MSDN) and Code Conventions for the Java Programming Language.
What is sensible is providing guidelines like bulk collection needs to be justified (not possible using SQL only) and use the limit clause to manage memory spend on the collection variable. Or how packages need to be used to modularise code, providing a public interface and private implementation.
Standards are about creating a sensible and easy-to-use framework for writing code. It is not about creating a list of a 1001 rules that a developer needs to remember and adhere to, as if the developer is now part of some weird religious sect that has rules for every single aspect of human behaviour.

ECATT coding standards

Hi all,
Anyone have documents related to the coding standards of eCATT sripts,
any template like thing to follow the coding of eCATT scripts,
What will be the best method to follow to achieve a good quallity of eCATT scripts
in performance and look and feel purposes,
If any one is haveing idea about the above mentioned points, please let me know,
Thankyou in advance,
Regards,
Chandra shekhar.A

Hi Chandra Shekhar,
There are no standard rules saying you need to follow these standards to prepare a eCATT as far as I am aware of.
All you could do is try to differentiate your script in 2 main parts..
Preparation
Executionable.
In the preparation part you perform all the preparation steps like:
Checking for necessary input values,
Manupulations to be done to the input values,
Adding prefixes or changing the dates, when they fall in public holidays etc to values in some cases....
These preparation stuff will help you very much to save a lot of executionable time as you would check for all the values in the beginning of the execution and if they fail at the preparation, you would save lot of time.
In the Executionable part,
Place all your recording ( SAPGUI/TCD/... )
All the runtime modifications / manipulations
Also use Message..EndMessage Blocks here..
Try to keep your script as indented as possible.
These are some points which might help you to have a good, understandable & indented scripts.
Hope this helps.
Best regards,
Harsha

Coding standards for developing java iviews

Hi All,
Are there any coding standards to be explicitly followed to develop Java iviews in SAP Enterprise Portal ? Does SAP has any specific java coding standards to get the SAP certification for the developed iviews ?
regards,
sreeram

Hi Sreeram,
> Are there any coding standards to be explicitly
> followed to develop Java iviews in SAP Enterprise
> Portal ?
No. What you can find (for example within the PDK doc or partially created by wizards) are templates for the different kind of iViews, especially for JSPDynPages. But you have to care - even these templates are not really "clean" - there are objects used to store data which shouldn't...
> Does SAP has any specific java coding standards to get
> the SAP certification for the developed iviews ?
No. What is needed is the proper use of namespaces, but this primarily concerns portal objects within the PCD. Some implementation things are to be considered, for example if i18n is offered, it really has to work. But SAP does not care about the source code of the iViews.
Hope it helps
