Newbie Development Question

I'm evaluating the G6 portal product and I'm working with the development tools to determine how easy/hard it will be create and maintain portlets. After reading through some of the documentation, I'm a little concerned. I've been trying to develop just simple portlets like "Hello World" using .NET and what I'm find is that any portlet that I design cannot be tested from within the IDE if I'm referencing the portlet API.
I know that that last statement can't be true. And, I've seen references to where I need to create a remote server and point that at the folder where I'm doing development on my machine. However, I haven't been able to find instructions on how to do that.
Can anyone point me in the right direction?

Hello Gordon,
SOA (Service Oriented Architecture) - as the name indicates, it's design is based on services. SOA is another integration technique which is used for small scale integration. SOA is an approach to have software resources in an enterprise available and discoverable on network as well defined services. Each service would achieve a predefined business objective and perform discrete units of work. The services are independent and do not depend on the context or state of the other services. They work within distributed systems architecture.

General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id. When engineering a logical model to a relational model, the added foreign key columns are all "id#". Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

Newbie script question... consecutive numbers with update.

complete newbie type question... this is also my first post. ( I am using CS3)
does anyone have a script which can make it so I can add numbers into the text consecutively.
for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
by inserting the three, the previous three became four.
Has anyone got something which might be useful in this regard.
Many thanks
Steve

i wanted to avoid footnotes as they leave a bar at the bottom of each page.
i wanted a script to do something similar to footnotes but not much further.
does anyone have just a simple script that can do what I asked?

Widget Development Question

I need help setting margins on my widget with CSS. I have messed around with the margin properties of CSS, but how do they work in a widget environment? When the CSS is in a widget, would the margin be counting from the edge of the background image? In Safari, the margin counts from the edge of the viewing window.
Please Help.
Thanks

Hi, the Apple Discussions are really meant for end users of Apple technologies, so it's usually hard to find answers to development questions here.
However, Apple does have excellent mailing lists (listservs) covering all their technologies for developers. If you post your question to "dashboard-dev" at lists.apple.com, you'll be sure to find a lot of helpful answers there. You can also try the forums at dashboardwidgets.com. Good luck!

Newbie XSan question - authenticating a computer from XSan Admin

Hello - I have a very newbie XSan question!
I have 2 computers that connect to an XSan. 1 I am having no problems with. The other I am unable to connect with.
When I look in XSan Admin the 2nd computer (the one that is not working) is not authenticated.
So I click on it and choose Authenticate. I enter what I know is an Admin username and password for the computer I am attempting to connect. The dot next to the computers IP turns green with 3 dots in it and then it turns gray again. It just does not connect.
What is the problem?
Is it licensing?
Thanks
Taj

You need a different license ID for each machine, plus the admin machine. Do you have that?

Development Question Pertaining to Discoverer and Oracle Apps

Hi All,
I have a Disco Development question. First of all I am in an Oracle Apps environment.
Here is my situation. I received a specification to make sure our End User Layer has the capability to create a workbook
which has the following information in it:
1. Onhand inventory by lot information using the GMF_PERIOD_BALANCES table.
2. Demand pegging (from the msc_demands table) associated with this onhand inventory.
3. Accounting cost information (GL_ITEM_CST information).
4. They also want more detailed item master information information (e.g. catalog descriptive element information and costing category).
Here is a solution to address this:
-Take existing inventory by lot views we have and use the the gmf_period_balances table in lieu of the mtl_onhand_quantity_details table. Within this same
view, add pegging information. This has been implemented in a development environment.
-Take existing costing views (using the component_cost_details table) and replace with the gl_item_cst.
-Take existing view associated with item detail information and make sure all catalog descriptive elements and costing category information have been added.
My next main dilemma for this problem is to address the best way to join these views in the Discoverer end user layer. Here are the approaches I see:
1. Encapsulate the item detail information with the onhand, period end with pegging view. Next, create a join with the costing view.
     pros: In my testing of this, the totalling works with extending item costing (item cost x onhand inventory).
     cons: Refresh times and scalability of this solution are concerning (consider a couple of people using this at the same time). Also, there is no nice
     way to join these two views (there is a n x m relationship between these two views). For instance, the costing calendar is used in the accounting costing
     view, and the general ledger calendar is used in the GMF_PERIOD_BALANCES table.
2. Abandon a two or three view approach. Create an uber view which encapsulates the onhand quantity, pegging, standard costing and item detail information.
     pros: A more simpler end user experience which should then allow for the totalling to work.
     cons: Very easy for an end user to obtain a result set which is part of a cartesian product (e.g. multiple general ledger periods are included in this workbook
     with multiple costing periods). Doubtful that this workbook would be refreshable.
3. Fan trap solution which would be some variation of onhand view being joined to an item details folder which is joined to the pegging details updated.
     pros: Without too much work, I am able to get this to work, except totaling.
     cons: Totaling.
     Please let me know what your thoughts are regarding the best approach.
     Thanks,
     Patrick

Hi,
Where you have complex joins I would always go for a single view. It keeps Discoverer simple and allows you to concentrate performance effort building the view. Generally you can build in conditions to stop a cartesian product.

NEWBIE SOA Question:Appl Development for SOA

This question may have been answered elsewhere; if so, my apologies.
As a newbie to SOA, I am trying to wrap my head around the question of how app. development for SOA differs from traditional models. For example, non-SOA environments there are few external considerations when coding a process,
but in SOA environments, I understand everything is a service.
Can someone provide a few code snippets as to how they would look in each environment?
I have read through several documents on SOA and have done the SOA tutorial, etc. but I have yet to see a side-by-side comparison of application code in SOA and non-SOA environments.
How would an architect plan the translation and mapping of business objectives and functional requirements into a technical solution for SOA, architecting the SOA solution ?
I would really appreciate any pointers (links to articles, etc.) in this direction. Thank you.

A developer question from a newbie

hi there!
i'm trying to improve my geek skills and could use some direction from smart people like yourselves.
all i know is some very basic html and photoshop that i learned 10yrs ago. think of me as a young grandma in terms of ability.
my goal is to be able to create my own website from scratch, or heck, even jazz up my posterous/ tumblr blogs. i know, how lame/ quaint. but we all start somewhere.
so, question: where to start?
i've been thrown all these acronyms, php, mysql, css, javascript -- and then html5 and css3! me no understand!
my computer genius brother tells me that i should learn the basics before learning dreamweaver...but i haven't a clue what that means. do i take a css class? an html5 class?
i'm in nyc and would ideally not like to spend a fortune on a class. i also do want an instructed class b/c i'm definitely one of those obnoxious kids that asks a bazillion questions to clarify. and bonus points if it's an intensive class b/c i'm impatient. wah wah.
many thanks,
steph

Steph
You have plenty of resourced available to you on line, without paying a penny. I guess though, it depends how quickly you want to get going and how best you learn.
If you search this forum there will be heaps of suggested links to help you brush up on the grand themes, specific techniquies and of course, Dreamweaver. In my mind the areas that you mention are all important, interelated but quite distinct. HTML and CSS are the building blocks of any web page, PHP/MySql are about building dynamic sites and Javascript helps add functionality and whistles and bells to the design. You can certainly get going with HTML and CSS and then add some of the other stuff without really knowing that much about them.
A good place to start is http://www.w3schools.com/

This Newbie Has Questions

Hi there. I am a newbie to Apple. I purchased the iBook last month and of course, when the MacBook (which had the features I wanted) came out, I rushed out and got one and I'm very pleased with my purchase - but I have a few "newbie" questions:
1) Printing on a PC based Linksys seems to be a nightmare. I can't get anything printed on the shared HP 2600N and HP1012 printers. I literally have to disconnect them from the PC and plug the USB directly to my MacBook to print. It seems like there should be a better, easier and MacFriendly way of doing this - anyone have an easy solution?
2) I'm going to purchase Windows XP so I can run my windows programs on this computer. Does anyone have any pre-installation advice?
3) I have a blackberry device that worked fine with my iBook, but does not work with my MacBook - any suggestions or is there a software compatibility patch?
4) I transferred everything from my old Mac to my new Mac with no problem. How can I migrate my contacts from Entourage to the Address Book?
5) I notice that sometimes the MacBook "stalls" or doesn't work fast in some functions...is it just me - I expect the machine to jump quickly...but sometimes I get that annoying pinwheel when opening programs.
Thanks for your help!

1) Printing on a PC based Linksys seems to be a

The problem is probably a driver issue.
Printing to a printer on a XP PC from a Mac running 10.4.x
http://www.ifelix.co.uk/tech/3015.html
You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
2) I'm going to purchase Windows XP so I can run my
windows programs on this computer. Does anyone have
any pre-installation advice?
Ensure you get a full version (not an upgrade version) and it comes with XP SP2 already.
Do not install Boot Camp on a critical machine and make regular backups of your data, this is beta software and there are bugs and issues.
5) I notice that sometimes the MacBook "stalls" or
doesn't work fast in some functions...is it just me -
I expect the machine to jump quickly...but sometimes
I get that annoying pinwheel when opening programs.
Are these Universal or PPC only applications?

I ended up uninstalling every java this and that.. and tomcat.
Then installing only the j2sdk1.4.0_03 SDK.
Then set up JAVA_HOME for all users and modified the path with full path to the bin (c:\j2sdk1.4.0_03\bin)
Lastly I reinstalled tomcat and, voila, everything was working.
It can be quite maddening when you THINK you did everything by the boook and something doesn't work. When you replied and confirmed that I was on the right track.. uninstalling and trying yet again became les frustrating an option.
Thanks.
BTW- I needed this env to do the projects in what sems to be a very interesting book.. "macromedia Flash MC application design and development" by Jessica Speigel .. published by New Riders.
Her flash help website is at www.were-here.com.. the projects in the book are for flash-based multiplayer games and multi-user formums and such.

Oracle BAM 11g - Deployments and development questions

Hi!
I have few questions related to Oracle BAM 11g developement and deployment processes. We are going to use that together with Oracle SOA Suite 11g ( BPEL / BPM processes), and now my questions are related to development phase:
1. If we have two or more Oracle BAM developers with their own Oracle BAM server instances, and we would like to share our development work, should/can we you same database repository to share the reports, data objects?
2. How we can copy Oracle BAM Data Objects, Reports etc from one environment (dev) to other environments (test, accept test, integration test, production) ? In software deployment projects (like Spring or Grails web-projects) we have used version control system and CI to build packages to different environments etc. How is the Oracle BAM deployment process actually "planned to be" since it uses its database repository to store objects and reports ?
3. The Oracle BAM itself has nice reports etc (Oracle BAM Client) that can be used using IE browser. How if we have to show/include those reports from Oracle WebCenter Spaces ? Is it possible and how?

Hi,
Were you able to find the answer to your questions? Especially the one, showing BAM reports in Webcenter Spaces?

Newbie wireless question (slightly off-topic)

I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

Sql developer: question about exporting data

Hi,
we're recently working with sql-developer. i've got a question about how we can export query results to txt/csv files for use in other applications.
First a problem: if we start a query that looks like this:
select * from
select * from A where start_date = &date
) a,
select * from B where start_date = &date
) b
where a.name = b.name
Sql-developer asks twice to input a value for the variable 'date', although it's the same variable and it's supposed to have the same value.
We solve this by making a script:
first we define the variable, then we put the query.
When we start the script, the query runs ok and sql developer asks to input the value for the variable once.
But now the result of the query is shown in the script output. The script output seems to be limited in number of lines and difficult to export.
So my question is: what's the best way to export query results to txt/csv files, avoiding the problem mentioned above?
i hope there is a solution where we can use a single query or script.
Thanks in advance!

Using bind variables like ":date" should solve the problem of being asked twice for the same thing.
Executing the query normally (F9), gives you the export options you require through the context menu inside the Results grid.

K.

SQL Developer question

Hi Folks
I am using SQL Developer tool. I have a procedure with compilation errors so i can see that procedure with red X mark in SQL Developer tool.
When am clicking on the procedure it is going to the editor there i can see "code"."grants","dependencies","references","details","profiles" tabs
But i can't able to see "Errors" tab in the editor. And main thing is i didnt see any red lines in the editor for the invalid procedure
And when i recompiled that procedure it got recompiled successfully and that red x mark is vanished.
Here my question is the "Errors" tab is only appears when the procedure/function/package has errors and surprisingly i didnt see any red lines in the editor for invalid procedure (may be my proc has no errors).
ps: i have asked this question in sql developer forum but i posted here as you may work on this
Thanks

Total newbie with questions

Hi, I've just started trying to create forms with Designer 7.0. I have managed to import a Word document and have found it easy to tweak the appearance and add different types of fields, but I have a couple of questions that I just can't figure out.
1. I have created text fields in certain areas, but when I preview the PDF, there is a "T" at the beginning of each field that I can't delete. How can I get rid of this marker?
2. I have to add several signature fields to some of the forms, and want at least one signature to make the entire form read-only. The forms will be electronically signed, and it is essential that no changes can be made once the signature has been applied, and that the signature itself cannot be copied and pasted into another record. How do I do that in Designer 7.0?
Thanks in advance. I'm sure these are pretty easy functions, but I just can't seem to figure them out on my own.

2. When you digitally sign a document, there is a green check mark that appears in the signature field. When you change the document, or sign a second field, that green check mark turns into a green check mark with a yellow caution triangle, indicating that the document has been changed since it was signed (in this example a new signature was added, but it could just as easily have been content that was changed). I assume that with Javascript you could go through and make all the fields read-only, but I'm not sure what you'd be accomplishing, since the signature field shows whether or not anything has been changed.
I don't know of a way to copy signatures into another record, so I think you're safe there.
