Online place for EP Development Practice

Hi All,
Is there any Online place for EP Development Practice?

Ganga

Hi Ganga,
The best option would be to download the [Trial version |http://www.sdn.sap.com/irj/scn/downloads?rid=/library/uuid/50c58b14-da6d-2a10-ca94-a3c0937828d6] and start exploring the Portal features. You can also go through the [help|help.sap.com] and lots of other training materials/ articles available on SDN
@Prasanna,
RAC is meant for ISVs and I don't think it is for individiuals to evaluate any ECC or Netweaver component.

Best practices for "designer - developer" interaction in Flex Mobile

Hi,
I'm starting development of a mobile software application and Flex Mobile is the platform I've chosen for that.
What is the best practice / recommended workflow for designer-developer interaction? For example in web application the designer provides HTML/CSS templates to the developer which integrates them in the Web Application. What is the analogue in Flex Mobile? What should I request as input from the designer?
I'll appreciate any hints, links, advises or previous experience on the topic.
Thanks!

If you're using Adaptive Web Design (CSS3 media queries), you can maintain one site with CSS Layouts optimized for different device widths.

If you're actually running separate web sites for mobile and non-mobile devices, have a look at this recent discussion:
http://forums.adobe.com/message/4177360#4177360
IMO, there is nothing wrong with providing links for mobile and non-mobile users to choose which site they would prefer to use -- especially for tablets who may have an interest in both.

Best Practices for Team Development

Hi!
I've a question regarding a project using JHeadstart 10.1.2. I've a small team that will work on a new project.
1. Which are the best practices to handle a project in a team environment? Besides using a version control system and so on. Is it advisable to use multiples Application Structures Files? One for each developer and for each "subapplication".
2. A component of the system is a kind of "Task Management System" that needs to be available across all the "sub applications" Which is the best way to share that component between the applications?
Best regards,
Gerardo

Gerardo,
Yes, we usually create separate application structure files for sub systems. Each subsystem is then accessed through a global button, so the subsystems can keep their own generated menu structure. This technique is also used in the JHeadstart Demo application, shipped with release 10.1.2.1 or higher.
For more info on team-based development, see this thread:
Re: Jheadstart, JDeveloper and CVS and TeamWork
Please create a new thread for your other question.

Looking for a best-practices guide for developing in TestStand

I am looking for a best-practices guide for developing in TestStand. LabVIEW has its style guides and books, but there is very little published about TestStand.
Also, and I mention this since NI checks these entries as well, how about adding TestStand to the NI Developer Zone?
Thanks in advance for any leads or documents you can provide!

Thanks! I was stuck on entering "TestStand best practices" into NI's search engine, and never thought of entering "TestStand style guide."
If anyone knows of additional pertinent content, I would appreciate hearing about it.

Developing Online Help for Mobile Applications

My company is just starting to develop applications for mobile devices (cell phone, iPad
, etc.). Can anyone tell me whether RoboHelp is the best Adobe application for devel
oping online help for mobile devices or if some other application should be used? Thanks.

Thanks for the insight. I haven't read about RH8 so wasn't aware of that difference. No, I haven't tried the demo yet. I guess that would be the logical next step. I've been trying to get to the STC web site to download the PDF file of the presentation, but can't get the web site to open. Oh well. Thanks again.

Best practice for team development

Hi,
We have a team of Java developers working on different parts of a J2EE application deployed on a NetWeaver server. Everyone needs to debug the application from time to time. How to configure the server for each developer to have ability to connect via remote debug? Run several instances with different ports? Run local environments with shared database? Any there any other options?
Thanks,
Victor.

Use NWDS for this please.

Look For Transport Best Practices

Hi,
I am looking for transport best practices, so please answer the following questions on how your place of business handles :
1. If an object is modified in development and you decide that you you do not wish to move the modifications forward - Do you;
    a. delete the transport and release the locks
    b. create a corrective transport and move the transport through production
    c. release the transport and never import it into the next system
    d. something different : (Please explain)
2. If a transport is imported into QA and then you decide never to move it to production, do you:
    a. delete the transport and release the locks
    b. create a corrective transport and move the transport through production
    c. release the transport and never import it into the next system
    d. something different : (Please explain)
Thanks Rob
[email protected]

I was always taught never to delete a transport. The changes should be reversed in the same transport and moved forward or released and the corrective transport moved forward in the same import queue.
If the transport goes to QAS then it needs to move to production. A corrective transport should be imported into production in the same queue.
I am sure you can get 20 different answers on this, but this is my policy.

Hi all, I upgraded my MBP to Lion , but on the screen where i need to type my password, click on my photo and it does not appear the place for me to type my password and it stay stuck there. Can anyone solve this problem for me?

Hi all, I upgraded my MBP to Lion , but on the screen where i need to type my password, click on my photo and it does not appear the place for me to type my password and it stay stuck there. Can anyone solve this problem for me?

Reboot the machine holding Command and r keys down, you'll boot into Lion Recovery Partition
In there will be Disk Utility, use that to select your Lion OS X Partition and Repair Permissions.
After that is done reboot the machine and see if you can log in.
If not repeat the above steps to get into Lion Recovery, get online and reinstall Lion again, it will overwrite the installed version and hopefully after that it wil work.
Reboot and try again.
If not follow my steps to create a Snow Leopard Data Recovery drive, then option boot from it and grab a copy of your files off the machine.
Then reinstall all your programs onto the external drive like setting up a new machine, then use Disk Utility to erase the entire internal boot drive (select the drive media on the far left, not the partiton slightly indented) format Option: GUID , 1 partition OS X Extended and then use Carbon Copy Cloner to clone the external to the newly formatted internal drive. Once that is finished reboot and disconnect the external drive.
Once you go that, boot into Snow Leopard and update to 10.6.8, use the AppStore and option click on Purchases and download Lion again and install.
Lots of work, but there is no Lion disks.

GeoRaptor 3.0 for SQL Developer 3.0 and 2.1 has now been released

Folks,
I am pleased to announce that, after 5 months of development and testing, a new release of GeoRaptor for SQL Developer 2.1 and 3.0 is now available.
GeoRaptor for SQL Developer 3 is available via the SQL Developer Update centre. GeoRaptor 3 for SQL Developer 2.1 is being made available
via a download fro the GeoRaptor website.
No release notes have been compiled as the principal developer (oops, that's me!) is currently busy doing real work for a change (another 3 weeks), earning a living
and keeping the wolves at bay. More extensive notes (with images) will be compiled when I get back. (Unless anyone is offering! See next.)
We are still looking for people to:
1. Provide translations of the English dialog menus etc.
2. Write more extensive user documentation. If you use a particular part of GeoRaptor a lot and think
you have found out all its functionality and quirks, contact us and offer to write a few pages of
documentation on it. (Open Office or Microsoft Word is fine.) Easiest way to do this is to simply
make screen captures and annotate with text.
3. Conduct beta testing.
Here are the things that are in the new release.
New functionality:
Overhaul of Validation Functionality.
1. User can specify own validation SELECT SQL as long as it returns three required columns. The SQL is thus totally editable.
2. Validation update code now allows user to associate a PL/SQL function with an error number which is applied in the UPDATE SQL.
3. UPDATE SQL can use WHERE clause of validation SELECT SQL (1) to update specific errors.
   NOTE: The generated UPDATE statement can be manually edited. It is NEVER run by GeoRaptor. To run any UPDATE, copy the statement
   to the clipboard and run in an appropriate SQL Worksheet session within SQL Developer.
4. Main validation table allows:
   a. Sorting (click on column header) and
   b. Filtering.
   c. Copying to Clipboard via right mouse click sub menu of:
      - Geometry's SDO_ELEM_INFO array constructor.
      - SDO_GEOMETRY constructor
      - Error + validation string.
   d. Access to Draw/Zoom functions which were previously buttons.
   e. Added a new right mouse click menu "Show Feature's Individual Errors" that gathers up all the errors
      it can process - along with the ring / element that is host to the error (if it can) - and displays
      them in the Attribute/Geometry tabs at the bottom of the Map Window (where "Identify" places its results).
      The power of this will be evident to all those who have wanted a way of stepping through errors in a geometry.
   f. Selected rows can now be deleted (select rows: press <DELETE> key or right mouse click>Delete).
   g. Table now has only one primary key column, and has a separate error column holding the actual error code.
   h. Right mouse click men added to table menu to display description of error in the new column (drawn from Oracle documentation)
   i. Optimisations added to improve performance for large error lists.
5. Functionality now has its own validation layer that is automatically added to the correct view.
   Access to layer properties via button on validation dialog or via normal right mouse click in view/layer tree.
Improved Rendering Options.
1. Linestring colour can now be random or drawn from column in database (as per Fill and Point colouring)
2. Marking of SDO_GEOMETRY objects overhauled.
   - Ability to mark or LABEL vertices/points of all SDO_GEOMETRY types with coordinate identifier and
     option {X,Y} location. Access is via Labelling tab in layer>properties. Thus, coordinate 25 of a linestring
     could be shown as: <25> or {x,y} or <25> {x,y}
   - There is a nice "stacked" option where the coordinate {x,y} can be written one line below the id.
   - For linestrings and polygons the <id> {x,y} label can be oriented to the angle between the vectors or
     edges that come in, and go out of, a vertex. Access is via "Orient" tick box in Labelling tab.
   - Uses Tools>Preferences>GeoRaptor>Visualisation>SDO_ORDINATE_ARRAY bracket around x,y string.
3. Start point of linestring/polygon and all other vertices can be marked with user selectable point marker
   rather than previously fixed markers.
4. Can now set a NULL point marker by selecting "None" for point marker style pulldown menu.
5. Positioning of the arrow for linestring/polygons has extra options:
   * NONE
   * START    - All segments of a line have the arrow positioned at the start
   * MIDDLE   - All segments of a line have the arrow positioning in the middle.
   * END      - All segments of a line have the arrow positioning in the END.
   * END_ONLY - Only the last segment has an arrow and at its end.
ScaleBar.
1. A new graphic ScaleBar option has been added for the map of each view.
   For geographic/geodetic SRIDs distances are currently shown in meters;
   For all SRIDs an attempt is made to "adapt" the scaleBar units depending
   on the zoom level. So, if you zoom right in you might get the distance shown
   as mm, and as you zoom out, cm/m/km as appropriate.
2. As the scaleBar is drawn, a 1:<DEMONINATOR> style MapScale value is written
   to the map's right most status bar element.
3. ScaleBar and MapScale can be turned off/on in View>Properties right mouse
   click menu.
Export Capabilities.
1. The ability to export a selection from a result set table (ie result of
   executing ad-hoc SQL SELECT statement to GML, KML, SHP/TAB (TAB file
   adds TAB file "wrapper" over SHP) has been added.
2. Ability to export table/view/materialised view to GML, KML, SHP/TAB also
   added. If no attributes are selected when exporting to a SHP/TAB file, GeoRaptor
   automatically adds a field that holds a unique row number.
3. When exporting to KML:
   * one can optionally export attributes.
   * Web sensitive characters < > & etc for KML export are replaced with > < & etc.
   * If a column in the SELECTION or table/view/Mview equals "name" then its value is
     written to the KML tag <name> and not to the list of associated attributes.
     - Similarly for "description" -> <description> AND "styleUrl" -> <styleUrl>
4. When exporting to GML one can optionally export attributes in FME or OGR "flavour".
5. Exporting Measured SDO_GEOMETRY objects to SHP not supported until missing functionality
   in GeoTools is corrected (working with GeoTools community to fix).
6. Writing PRJ and MapInfo CoordSys is done by pasting a string into appropriate export dialog box.
   Last value pasted is remembered between sessions which is useful for users who work with a single SRID.
7. Export directory is remembered between sessions in case a user uses a standard export directory.
8. Result sets containing MDSYS.SDO_POINT and/or MDSYS.VERTEX_TYPE can also be written to GML/KML/SHP/TAB.
   Example:
   SELECT a.geom.sdo_point as point
     FROM (SELECT sdo_geometry(2002,null,sdo_point_type(1,2,null),sdo_elem_info_array(1,2,1),sdo_ordinate_array(1,1,2,2)) as geom
             FROM DUAL) a;
   SELECT mdsys.vertex_type(a.x,a.y,a.z,a.w,a.v5,a.v6,a.v7,a.v8,a.v9,a.v10,a.v11,a.id) as vertex
     FROM TABLE(mdsys.sdo_util.getVertices(mdsys.sdo_geometry(2002,null,null,sdo_elem_info_array(1,2,1),sdo_ordinate_array(1,1,2,2)))) a;
9. A dialog appears at the end of each export which details (eg total) what was exported when the exported recordset/table contains more
   than on shape type. For example, if you export only points eg 2001/3001 from a table that also contains multipoints eg 2005/3005 then
   the number of points exported, and multipoints skipped will be displayed.
10. SHP/TAB export is "transactional". If you set the commit interval to 100 then only 100 records are held in memory before writing.
    However, this does not currently apply to the associated DBASE records.
11. SHP/TAB export supports dBase III, dBase III + Memo, dBase IV and dBase IV + Memo.
    Note: Memo allows text columns > 255 characters to be exported. Non-Memo formats do not and any varchar2 columns will be truncated
    to 255 chars. Some GIS packages support MEMO eg Manifold GIS, some do not.
12. Note. GeoRaptor does not ensure that the SRID of SDO_GEOMETRY data exported to KML is in the correct Google Projection.
    Please read the Oracle documentation on how to project your data is this is necessary. An example is:
    SELECT OBJECTID,
           CODIGO as name,
           NOME as description,
           MI_STYLE,
           SDO_CS.TRANSFORM(shape,'USE_SPHERICAL',4055) as shape
      FROM MUB.REGIONAL;
13. NOTE: The SHP exporter uses the Java Topology Suite (JTS) to convert from SDO_GEOMETRY to the ESRI Shape format. JTS does not handle
    circular curves in SDO_GEOMETRY objects you must "stroke" them using sdo_util.arc_densify(). See the Oracle documentation on how
    to use this.
Miscellaneous.
1. Selection View - Measurement has been modified so that the final result only shows those geometry
   types that were actually measured.
2. In Layer Properties the Miscellaneous tab has been removed because the only elements in it were the
   Geometry Output options which have now been replaced by the new GML/KML/etc export capabilities.
3. Shapefile import's user entered tablename now checked for Oracle naming convention compliance.
4. Identify based on SDO_NN has been removed from GeoRaptor given the myriad problems that it seems to create across versions
   and partitioned/non-partitioned tables. Instead SDO_WITHIN_DISTANCE is now used with the actual search distance (see circle
   in map display): everything within that distance is returned.
5. Displaying/Not displaying embedded sdo_point in line/polygon (Jamie Keene), is now controlled by
   a preference.
6. New View Menu options to switch all layers on/off
7. Tools/Preferences/GeoRaptor layout has been improved.
8. If Identify is called on a geometry a new right mouse click menu entry has been added called "Mark" which
   has two sub-menus called ID and ID(X,Y) that will add the labeling to the selected geometry independently of
   what the layer is set to being.
9. Two new methods for rendering an SDO_GEOMETRY object in a table or SQL recordset have been added: a) Show geometry as ICON
   and b) Show geometry as THUMBNAIL. When the latter is chosen, the actual geometry is shown in an image _inside_ the row/column cell it occupies.
   In addition, the existing textual methods for visualisation: WKT, KML, GML etc have been collected together with ICON and THUMBNAIL in a new
   right mouse click menu.
10. Tables/Views/MViews without spatial indexes can now be added to a Spatial View. To stop large tables from killing rendering, a new preference
    has been added "Table Count Limit" (default 1,000) which controls how many geometry records can be displayed. A table without a spatial
    index will have its layer name rendered in Italics and will write a warning message in red to the status bar for each redraw. Adding an index
    which the layer exists will be recognised by GeoRaptor during drawing and switch the layer across to normal rendering.
Some Bug Fixes.
* Error in manage metadata related to getting metadata across all schemas
* Bug with no display of rowid in Identify results fixed;
* Some fixes relating to where clause application in geometry validation.
* Fixes bug with scrollbars on view/layer tree not working.
* Problem with the spatial networks fixed. Actions for spatial networks can now only be done in the
schema of the current user, as it could happen that a user opens the tree for another schema that
has the same network as in the user's schema. Dropping a drops only the network of the current connected user.
* Recordset "find sdo_geometry cell" code has been modified so that it now appears only if a suitable geometry object is
in a recordset. Please note that there is a bug in SQL Developer (2.1 and 3.0) that causes SQL Developer to not
register a change in selection from a single cell to a whole row when one left clicks at the left-most "row number"
column that is not part of the SELECT statements user columns, as a short cut to selecting a whole row. It appears
that this is a SQL Developer bug so nothing can be done about it until it is fixed. To select a whole row, select all
cells in the row.
* Copy to clipboard of SDO_GEOMETRY with M and Z values forgot has extraneous "," at the end.
* Column based colouring of markers fixed
* Bunch of performance improvements.
* Plus (happily) others that I can't remember!If you find any bugs register a bug report at our website.
If you want to help with testing, contact us at our website.
My thanks for help in this release to:
1. John O'Toole
2. Holger Labe
3. Sandro Costa
4. Marco Giana
5. Luc van Linden
6. Pieter Minnaar
7. Warwick Wilson
8. Jody Garnett (GeoTools bug issues)
Finally, when at the Washington User Conference I explained the willingness of the GeoRaptor Team to work
for some sort of integration of our "product" with the new Spatial extension that has just been released in SQL
Developer 3.0. Nothing much has come of that initial contact and I hope more will come of it.
In the end, it is you, the real users who should and will decide the way forward. If you have ideas, wishes etc,
please contact the GeoRaptor team via our SourceForge website, or start a "wishlist" thread on this forum
expressing ideas for future functionality and integration opportunities.
regards
Simon

Thank you for this.
I have been messing around with this last few days, and i really love the feature to pinpoint the validation errors on map.
I has always been so annoying to try pinpoint these errors using some other GIS software while doing your sql.
I have stumbled to few bugs:
1. In "Validate geometry column" dialog checking option "Use DimInfo" actually still uses value entered in tolerance text box.
I found this because in my language settings , is the decimal operators
2. In "Validate geometry column" dialog textboxs showing sql, doesn't always show everything from long lines of text (clipping text from right)
3. In "Validate geometry column" dialog the "Create Update SQL" has few bugs:
- if you have selected multiple rows from results and check the "Use Selected Geometries" the generated IN-clause in SQL with have same rowid (rowid for first selected result) for all entries
Also the other generated IN clause in WHERE-clause is missing separator if you select more than one corrective function
4. "Validate geometry column" dialog stays annoyingly top most when using "Create Update SQL" dialog

Online Help for Oracle HRMS Self Service System

I am looking into developing context-sensitive online help for an Oracle HRMS Self Service application. There is currently no online help for the application; all help is provided in printed and online docs, so users are having trouble navigating to the info they need. Help is needed! My initial questions are:
Would I need to create OHJ or OHW?
Could I use RoboHelp to develop the content?
Is there a reference document you can point me to?
Thanks
Belinda

Hi Belinda,
You would create Oracle Help, and then deploy it using OHJ or OHW.
The format of the help is the same. There is nothing specific that needs to be done for one or the other. If your system i s a Web application, you would use OHW and otherwise, you would use OHJ.
You can read more about Oracle Help on OTN at http://www.oracle.com/technology/tech/java/help/index.html.
(Read the FAQ for more information about the choice between OHJ and OHW.)
Personally, I would not recommend RoboHelp to create Oracle Help. RoboHelp has a lot of nice features, but the Oracle Help output feature is fairly buggy, especially if you are creating a large helpset, or a helpset that has subhelpsets.
At Oracle, a lot of help development is done using DreamWeaver and an in-house build tool, called the Oracle Help Build Tool. This is available for free. Send me a mail ([email protected]) if you want a copy.
Regards,
Pete

hi, we are using mac mini's for our developement purpose. connecting the same through using Real VNC. Mac mini's are late 2009 and 2010. Now we have upgraded them to 10.8.5. after upgrading having display issues after launching the simulators, we are unable to view the icons we need to move the simulator (into different places) to view the icons.
Also we are having Mac book pro's (Late 2009 & 2010) after upgrading them to 10.8.5. Unable to launch the mac, getting only white screen with apple icon.
Let me know is there any specific Hardware (Graphic Cards) we need to use for the same.

NetBeans or Eclipse: Which is better for GUI development ?

I am relatively new with JAVA, came from embedded software domain mostly in C.
My interest is to learn and develop the GUI applications using Swing.
I am currently in a process of evaluating the IDEs, Eclipse and NetBeans on Linux desktop environment (SuSE 10.3).
My primary findings found that, NetBeans is better equipped with GUI development while Eclipse needs to have a plugin installed.
For GUI development, I found that few of my fellow Java developer friends have mixed feelings about these two wonderful IDEs, in summary here are the comments:
1) Developing GUI is better without any assistance from built in designers of IDEs (e.g. NetBeans or Visual Swing of Eclipse). Because, they put extra 'garbage" codes which are very much IDE specific.
2) GUI development in NetBeans is faster and more productive than Eclipse
3) Visual Swing for Eclipse is not a matured product and it is far inferior than NetBeans' capabaility
Now I ask a question, what is the best practice to adopt for starting the GUI development ? NetBeans or Eclispse or IDE-less development ?
Thanks.

NetBeansThis is my preference for IDE's. Please note that as I stated that is my preference. There isn't any best, some are clearly better than others for one reason or another, but once again, that boils down to personal preference.
EclispseNot my preference.
IDE-less development ?IMO: that is just silly. Unless you just enjoy tons of typing; why would you ever embark on doing something without a tool to speed up the process. Now that is not to say that in using your IDE you should start out by just dragging and dropping up a storm and merrily running down the road in ignorance until you hit a rough spot and have things dramatically pointed out that you've really not a clue about what is happening. Use the IDE, but learn how to do the manual processes along with it. That means that sometimes you'll not drag and drop to build your GUI, you'll actually code the entire thing. And you really should learn to do things command-line like compile. Do yourself a really big favor too, learn the debugger. The integrated debuggers is, perhaps, one of the best inventions in productivity tools that has as of yet been invented for developers.
In any case, have fun... choose what you like, it really does come down to personal preference. I've worked in several shops over the years and most have come to the conclusion that if you can get the work done, and have projects that others can use, then to each their own preferences. The discussion rages on for and against each of the systems that you have mention--each have valid arguments--it boils down to what do you want and like.
