JPA and embedded objects

I am try to figure out the best way to reuse the same @Embeddable class in multiple Entity Beans (EJB 3). I am mapping some legacy data where an address is used in multiple tables. The problem is that the address is not composed of a standard set of elements in all tables.
Ex.
Table - ServiceRequest
HouseNumber
HouseSuffix
StreetDirection
StreetName
StreetSuffix
City
State
Zip
Table - ParcelOwner
Address
City
State
Country
Zip
You can see that the address is non standard among tables. Should I just create an inheritance hierarchy with the common elements (City, State, Zip) in the super class and subclass the other combinations? I am attempting to place validators in the entity bean and want to not repeat the same validators in multiple places.
Thanks for any guidance.

Applescript problems with character offsets and embedded objects in Pages

https://discussions.apple.com/thread/2550810?start=0&tstart=0
The above discussion is archived, but I've noticed a problem witht he solution it proposes.
Essentially, the problem seems to be that the character offset of a selection becomes either inaccessible or out of sync when embedded objects are present in the file.
The following document can be used to demonstrate:
http://images.apple.com/support/pages/docs/ePub_Best_Practices_EN.zip
I've slightly modified the script fromt he previous thread, so here's my own script:
tell front document of application "Pages"
          set C to character offset of (get selection)
          set N to 0
          repeat with P in (get character offset of paragraphs)
                    if P > C then exit repeat
                    set N to N + 1
select paragraph (N + 1)
          end repeat
          N
end tell
This script is supposed to select the next paragraph in a document, when given a selection. The intention is to call it recursively to get each paragraph of the document in turn.
At the start of the document, it functions correctly, however when it gets to the embedded pictures, lines and table of contents, things start to break. This wouldn't be so bad, because I could simply ignore paragraphs that contains those embedded objects, but the real problems arise in the normal text below these objects.
If you place the cursor on the 3rd page of that document, in an ordinary paragraph, for example, this script will simply return the same paragraph over and over. The reason for this is that the character offset of the paragraphs is being thrown off, so the if statement gets hit too early. You can also see this if you look at the character offsets of the word "Introduction" in the heading at the top of the 3rd page. You'll notice that the character offset is duplicated for a couple of letters, and is out of sync with the index of the character itself.
What I need is a script that will take a selection (of any type), and simply return the correct index of the paragraph containing it every time. It doesn't seem like a difficult thing to do, and since the paragraphs are accessible by index, they should be able to return their index to the user. I have a feeling Apple need to add this functionality to the Pages Applescript dictionary, and they definitely need to fix the bug where the character offsets go out of sync after embedded objects. These are really quite bad problems.

I have tested it with the document referred to by andyboyd. When the first word (“Introduction”) of the first paragraph of page 3 is selected, your script returns {10}, while it returns {12} when the second word (“to”) of the same paragraph is selected.

Thanks Pierre.
Ok, the error is that I mixed the variable N and N1, during the renaming of variables
return N - 1 must be return N1 - 1 -- return the index
Here the corrected script :

                  set N1 to N
                  repeat -- check the character offset of the selected line
                     if N1 = tc then return tc -- it's the last paragraph
                     select paragraph N1 -- select next paragraph

JPA and JSF - Problem persisting object

Hi all.
I'm having some trouble with JPA, persisting an object to a MySQL table.
Let's say I have a simple bean, Message:

     private String author;
     public String getMessage() {
          return this.message;
     public void setMessage(String message) {
          this.message = message;
     public String getAuthor() {
          return this.author;
     public void setAuthor(String author) {
          this.author = author;
}And a controller for this Message bean:
package my.package;

Can anyone see what I'm doing wrong? The Message doesn't get added to the table in my database, and I get a NullPointerException in the method MessageController.save() on the property MessageController.message - which I have specified in the faces-config.xml. Shouldn't that be enough? What have I missed?

Ok, I have (re-)located the problem. It's not my Message property which gets a NullPointerException - it seems like the problem is with my EntityManagerFactory instance. The PersistenceUnit don't get assigned, even though I declare it in my persistence.xml file.
Maybe it is something wrong with my file structure?
The .war file have this structure:
- WEB-INF
     - classes
          - my
               - package

Excel 2013 "cannot use object linking and embedding error"

Hi
We are using excel export as pdf functionality and have the following DCOM configuration
1.start->run and type 'DCOMCNFG'
2: Open 'DCOM Config' and locate 'Microsoft Excel Application'
3: Set its identity to 'This User' and give specific service user
On opening excel we are getting "cannot use object linking and embedding error" and the microsoft sugestions tells to change to launching user which is not an option for us,Is there any other suggestion to fix this issue by keeping Dcom
configuration with'This User'
Thanks in advance
Pradeep

Hi
when excel is opened, a warning pops up saying "Cannot use object linking and embedding" . This
fix change the DCOM ID to Launching User) does not work for us. We need the Excel DCOM ID to use a particular user "domain\user" in order to access excel from our website.
Is there any other suggestions
Thanks in advance

Trex error: No embedded object found in document (Errorcode 14037)

Hi,
we have following problem with our crawler:
in the crawler 50 % of documents are returning the error "No embedded object found in document (Errorcode 14037)" and are not displayed in the trex monitor. All other documents are indexed correctly an are in the trex monitor in "OK".
We are on Stack 14 Patch 4.
Regards,
Gerhard

Hi Gerhard,
Typically, errors codes 14XXX are related to filter problems during the preprocessing of documents. Details about TREX error codes are explained in the help portal and in the note 898404.
Unfortunatelly, filter problems could not be easily fixed. However, a good starting point would be to use a newer TREX release. If this doesnt help please open a Customer Message and attach documents, which causes the mentioned error. Please attach only not sensible documents!
Kind regards,
Roland

Embedded objects when converting a word document

Hello ng,
a word document contains other documents as embedded objects shown as a symbol. When converting this document with Acrobat Standard or Professional the symbols are converted as non functional picture. So the embeddes document can't be opened.
So here's my question: Is it possible to convert embedded objects shown as symbol to functional embedded object within PDF?
Example is shown below.
Many thanks!
Susanne

It cannot be done. For all intents remember that creating the pdf is akin to printing the document out. If you were to print document to your printer, you would not expect to be able to click on the paper to launch the object. Now it is true that one can have things like hyperlinks preserved, but specialized coding was created for this functionality and is not available in all applications nor on all platforms. However, your wish is a reasonable feature request. I suggest you might ask here:

Importing Power Point and Embedding Video in Captivate Question

I am new to Adobe Captivate, but I have heard the following:
1)     I can import a power point slide directly into Captivate 5.5.
2)     I can add a action buttion that when click, can play a short video embedded within one of the slides.
My objective is:
1)     When I click that action buttion, I want to play that short video embedded within one of the slides.
2)     Each slide will have an action buttion, and embedded slide of video (different video).
3)     When the video is completed, it returns back to display the original slide
4)     The user can just look at the slide and just move to the next slide without showing the video.
To accomplish this in Captivate 5.5, can I do this ?
1)     I understand that one must place a button on the converted slide and also embed the video to another slide. This is done by using the tool bar.
Is it possible to do this using programing scripts or anything ???    I would have a many slides to do, and I would like to automate this process.
I would appreciate any suggestions and help.
Thank You,
G

Hi Eddie
You will be able to use the Adobe Captivate he has option in
order that you bring PowerPoint, videos in flv for inside him and
to go out how swf

JPA and CAF BO - are there any editors of the JPA data (like CAF)?

Hello!
As you know SAP invented some layer above JPA and called it CAF. There is a very convenient way to edit data in CAF.
But now I have to create a complex database scheme, also with CAF doesn't allow us to work with objects. So we can't use someObject.getChildren().
So my question is are there any editors of the JPA data (like it is done in CAF)?

Hi Kirill,
at the beginning of our project at the end of 2009, we did a deep analysis of CAF since our architect vehemently suggested to use this framework.
First about the history and purpose of CAF: Initially, CAF was never meant to be a layer above CAF since CAF was invented in the time before EJB 3.0 and JPA standard where writing persistence with EJB 2.x CMP forced the developer to write pages of boiler plate code. This background was approved by SAP.
With upcoming of JPA, CAF ist mostly useless (except for very simply structured data) and prevents you from writing good software.
It is easy just to write @Entity, @Id and @OneToMany (for complex database schemes) and CAF forces you to use an ugly, imperformant database scheme (e.g. CAF uses mapping tables even for 1:n relationships, a clear antipattern!)
The CRUD-services generated with CAF are a pain, too. Usage of pessimistic locking is not up to date for web applications.
With your complex database schemes, you exceed the limit of CAF.
(We decided not to use CAF and did never regret this.)
Concerning your question: There is an "JPA Details" view in NWDS that might help you. It needs JPA Persistence facet on your project to work. Developed by SAP. For JPA beginners, it is a good cheat sheet for JPA annotations and their attributes.
You do not need more since a JPA POJO is easy to code.

Rolf

Copy & paste embeded object to file system

Cross-post at:
http://stackoverflow.com/questions/27685791/copy-paste-embeded-object-to-file-system
Background:
I wrote a large piece of VBA code in an Excel workbook to help handle a lot of repeating jobs. I found it is painful to maintain and modify the code by using the "pool" VBA Editor. Then, I decided to move those VBA code to C# solutions, which I
suppose I can benefit from the modern editor - Visual Studio.
Problem:
Although I don't know too much about VBA, I know even less about C#. Hence I got some problem when I try to "translate" my VBA code to C#, and here is one of them:
I create a document-level solution for Excel. I need to embed some files (.cab, .exe) into the solution, so when I run a method (e.g. by clicking a button), those files will be copied to the file system, and do some job.
In VBA, I embedded those files in the Excel workbook, then I can copy the embedded objects to the clipboard by using the following VBA code:
Sheet1.OLEObjects("obj_cab").COpy
And then I can paste the object to the file system by using the following VBA code:
CreateObject("Shell.Application").Namespace("C:\Sample\").Self.InvokeVerb "Paste"
In the C# solution, I can use the following equivalent method to copy the embedded object to the clipboard:
Microsoft.Office.Interop.Excel.OLEObject OLEobj = (Microsoft.Office.Interop.Excel.OLEObject)sheet1.OLEObjects("obj_cab");
OLEobj.Copy();
Then I stuck here, I don't know how to get this object from clipboard and put it to the file system. The 'CreateObject' method does not exist in C#.
Anyone can help? Either a better way to embed those files or a working way to paste those objects (files) from clipboard to the file system?
Thanks a lot!

Hi FantaC,
It's possible to save the oleobject to the disk. But it's not very simple. Because when you call the Copy method of OLEObject to clipboard, it's actually not the exact the oleobject file itself, it's actually a wrapper of the file, it means that it has different
file headers and some other information from the original oleobject file.
To save oleobject on the disk, you need to analyze the byte array by yourself, this would be a little complicated. You could check the answer in this thread for the code sample:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/1ab7a178-8021-4c67-a14b-5031a254fd9c/saving-oleobject-content-to-a-file

Custom Mapping: Storing embedded objects to column of Oracle Object type

Hello,
How hard in your opinion it would be to write custome mapping to store an
embedded object which only have simple fields in it (no references to other
persistent classes) to oracle object column. What superclass is the best for
the job?
Simplest approach I see is to define "none" mapped class for my embedded
object and use transformation mapping to do the job
What if I need to reference other persistent objects in my embedded one - do
you think it will make any difference?
Thank you for your assistance

overriding loadProjection() took care of this issue

Looks like transform mapping would not work - Kodo does not support object
mappings (use stream instead) or I am missing something?

How do I change colour profile of embedded objects?

One of my Illustrator CS6 documents was intially created some time ago without paying much attention to colour management issues. I am now trying to put that right and have assigned the document a profile of Adobe RGB (i998). However, each time I open it I am warned that 'The document has an embedded color profile that does not match the current RGB working space'. It also says that the embedded profile is sRGB, while my working space is Adobe RGB. I get this message three times and am assuming that it refers to embedded objects.
So far, I have failed to find a permanent solution. Do I have to reimport all items that may have a colour profile, having first ensured that they are tagged as AdobeRGB?
David

Hi Monika,
First of all, let me apologise for using the word 'embedded' instead of 'linked'. I was distracted by the fact that the doc in question (an award certificate) is embedded in a Microsoft Access report. That being said, I have now found that all the linked logo images in this Illustrator doc are GIFs or TIFs that don't accept a colour profile (and thus cannot be the trigger for my profile warnings).
I use a Canon 5D and (rightly or wrongly) have chosen to standardise on a CS working space of Adobe RGB. However, your reference to digital photos is not relevant in this case as there are none in the document. My only concern is to make this document match my working space and no longer trigger irritating profile mismatch warnings. My overall objective is to ensure that the colours will all be correct when it goes to a printer (one of our sponsors, a UK colour paper manufacturer, will be printing the final certificates from a PDF file).

Embedded Objects (User Defined SCO)

Hello Patrick,
Do you have any timeframe for implementing support for embedded object
and/or user defined SCO
http://bugzilla.solarmetric.com:8080/show_bug.cgi?id=50
I wish it were available, makes many things much cleaner ....
Alex

Alex,
Embedded object support is currently slated for 2.3, which is where
we're putting a good deal of DB mapping improvements. I cannot commit to
a date for 2.3.0, however, our goal is to get it out around late June or
early July.
We will very likely have a beta version of it available before then.

What are the relation between JPA and Hibernate, JPA and TopLink?

What are the relation between JPA and Hibernate, JPA and TopLink?
Can JPA instead of Hibernate and TopLink?

The Java Persistence API (JPA) is the object relational mapping persistence
standard for Java. Hibernate and TopLink provide an Open source Object-relational mapping framework for Java.
They provide an implementation for the Java Persistence API. In my opinion, both Hibernate and TopLink provide support to JPA
and they can also be regarded as the complementary to JPA.
Let's wait to see other person's opinions.

Open embedded object in Word via a hyperlink

I have a Word document with embedded PDF files. I would like to create a hyperlink (or maybe a button), that when click opens the embedded PDF. Used the hyperlik option, but it just takes you to the location of the Word document where the embedded PDF
resides.Adrian Hernandez

Right-click the embedded object. On the context menu, click the Object command, and then click Convert. In the dialog box, select “Display as icon.”
Stefan Blom, Microsoft Word MVP
Can you provide better steps and clarify what version of Word this will work for? I don't see the options you mentioned in Word 2013.
