JDeveloper custom UML extension

Hi,
I need to develop an extension that would alow the user to draw an activity diagram and export it in a specific xml format (a non standard format with references to existing classes in the project).
For instance an activity in my diagram would point to a class in the project (letting the user choose the class to point to once the activity is drawn).
Can you please help with a sample plugin that alows the drawing of diagrams and the usage of custom elements for that diagram (like the elements specific to an activity diagram, class diagram etc..).
If possible can you point me to some code that would teach me how to build a plugin that alows the user to design a diagram ?
Thank you,
Florin

Guss,
Thanks for the answer. I guess I'll have to setle for that at the moment, though it looks like it is not that dificult to find a way to generate custom activity diagrams.
Being the product manager, here is some backgroud information that may be of interest to you, regarding my initial question.
I need this for an existing plugin I have developed here at Service Engineering that is just a much better JHeadStart.
Given a database it basically builds all the objects mapping the table, creates the toplink-deployment-descriptor.xml for them and builds a complete TopLink-Struts we application using ONLY java (no esoteric bc4j in there). It builds all the TopLink layer dao classes, all the action classes for struts and all the jsp pages.Also creates the struts-config.xml for all that.Also a an ant build file and a security configuration file for user roles per entity object.Thus the result is a complete deployable web application, written using plain simple java, with toplink persistance, that allows the user to do CRUD operations on all entities. It discoveres automatically all the associations and agregations between objects and builds the UI acordingly.It's quite impresive and very fast, which equals this : If you have the data model, you can build an evolutionary (RUP) prototype, that does CRUD, in less then a minute.There are no tools aut there that can mach this.
As most web applications olny do CRUD on a given data model (see catalogs, forums, hr management systems, project management systems, ..etc) what we have right now is good enough. But I wanna take it further and add support for an open sourcce very light and robust workflow engine, so that, once the crud aspect of the app is covered the user can start building the business logic on the existing entities..That's why I need a custom xml format outputed and the ability to link activities to classes in a project...so that the user can put some business "sense" into the generated classes, using the same plugin.
For the prof of concept, I guess I'll have to setle for your solution, but I don't think it will be viable on a longer term..
Even so, thanks a lot for the advice, it will keep things rolling..

How to Test SSRS Custom Data Extension in TSql

Hi There,
I have created a custom data extenstion for SSRS 2008 Reporting Service.
I can test the CDE in the Report DataSet -> DataSet Properties -> Query Designer -> Run Query.
In the Command Text I pass parameters to the invoked VB code which is of type "BaanstedeCds" then name of my custom data extension.
I can even Attach the Visual Studio VB Code Project that is invoked by the Query Designer an debug the code.
The custom data extension works perfectly in SSRS.
However I have not found a way yet to run BaanstedeCds (with a parametertext) from within SSMS 2008 by using an T-SQL statement!!! Is there a way to use the SSRS Custom Data Extension in Sql Server Management Studio using the dataset type I used in
SSRS 2008?
Because I am leaving the path of using Custom Assemblies in SSMS, for deploying an testing that way is undoable for me.
I is to complicated and in order to properly debug these routines the entire solution of multiple projects is deployed each time even the slightest change has been made to the VB code. Also if I want to deploy from Test to Production it is very hard. I have
to detach the databases etc, ect. Note my previous question about this subject that remained unanswered!!!
Using the Custom Data Extension the problems are a lot less. However I how do I use a routine in the CDS in T-SQL, like I could invoke a routine in the Custom Code Assemblies?
I "hate" CLR routines. I have extreme trouble managing these CLR's as I explained in my post and other posts in the past.
You just cannot build a maagable system that way.
I had to convert all the CLR's (I had a lot of them) to Custom Data Extension Functions, as they do not have all the drawbacks of CLR's.
And using the CDE with all the converted CLR's in it works much better for me in the Report Manager.
However in order to test de CDE I must invoke the CDE in a Windows Form something like this:
Private Sub cmdGetData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGetData.Click
Dim CommandText As String = ""
' Get Parameters for CDE GetData
CommandText = txtAdoCds.Text
Dim Rdr As New BstCds.BaanstedeCdsReader(CommandText)
' Invoke GetData Function of CDE Rdr
' Input: CommandText: txtAdoCds.Text = TextBox on TestForm
' Output: DataTable: RdrDataTable
Call Rdr.GetData(CommandText)
If Not Rdr.RdrRetVal Then
GoTo End_Method
End If
' Show DataTable: RdrDataTable (in Excel)
If Not BstOff.ToonTabel(DataTabel:=Rdr.RdrDataTable) Then
Exit Sub
End If
End_Method:
End Sub
'=========================================================================
' File: BaanstedeCdsReader.vb
' Summary: Provides a means of reading one or more forward-only streams
' of result sets obtained by executing a command at a data source,
' and is implemented by Baanstede Data Processing Extensions
' that access BaanstedeIw3-routines.
'=========================================================================
Public Class BaanstedeCdsReader
Implements IDataReader
#Region "Public Variables"
Public RdrRetVal As Boolean = False
Public RdrSqlSel As String = ""
Public RdrDataTable As DataTable = New DataTable
#End Region
#Region "Constructors"
#End Region
#Region "IDataReader Members"
#End Region
' GetData '
#Region "GetData Method"
'==================================================================================================
'We are executing the command using the connection string that connects to the Active Directory.
'Hard coding of the connection string is because it is the same for all the ADs.
'Once we read the data using a DataReader, we place the same in a DataTable so that can be used for
'Other processings.
' Public Sub GetData(ByVal _CommandText As String)
' Output in Public RdrDataTable As DataTable
'==================================================================================================
Public Sub GetData(ByVal _CommandText As String)
' Ophalen Data in DataTabel '
RdrRetVal = False
' Fills RdrDataTable Using _COmmandText
RdrRetVal = True
End Sub
But can I invoke Report Manager Source Type BaanstdeCds's .BaanstedeCdsReader.GetData(CommandText) in TSQL any other way then using CLR ?
Regards Jos
It works, but it does not work (The program runs, but does not produce the desired result)

Hi Josje,
Thank you for your question.
I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated.
Thank you for your understanding and support.

DW CS3 - custom file extension no longer working correctly

Hi - for a particular job, I needed to use a custom file
extension .htmx and it has been working fine.
However, I went into DW CS3 today, and the file opens in the
DW editor, but the code coloring and code hints etc seem to be
broken.
I've checked the Extensions.txt and MMDocumentTypes.xml
files, and all seems present and correct - see
this screencast to
see the problem.
Any ideas why it's not working? (I'm on Vista Business, but
it has definitely been working and now isn't....)
Mike

Well, I managed to fix it by overwriting my
MMDocumentTypes.xml file with a clean version from another machine.
Weird.

Error in the execution of custom billing extension in PA module

Hi All ,
We had a requiremnet for creating the custom billing extension similar to the standard Revenue calculation billing extension . The change required in the formula for calculating the revenue was the Actual total burdened cost will be the Actual total burdened hours and Budgeted baselined burdened cost will be the Budgeted baselined burdened hours .Rest of the entity in the standard revenue calculation program will be as per the standard revenue billing extension.
The standard formula is as follows :
(1) revenue amount = Lesser of (Remaining Funding Available if hard limit used) and ((AC / BC (BR – ER) – AR)
I created a package which will get the value of AC and BC as per the client requirement . Defined the Extension using PROJECT BILLING SUPERUSER >> SETUP>> Billing >> Extension screen .
This extension was then assigned to a project type . WE created a project using the same project type . When we fire PRC: Generate Draft Revenue for single project and pass the project number it first calls the Standard billing extension and then the custom one becoz of this there is error in calculating the revenue through it .
We are not sure where we are going wrong . The standard extension has been end dated too ..still everytime it executes the standard and then the custom one .
Has one faced such issue ? Request for some pointers to solve the issue.
Thanks and Regards

Hi,
My issue got solved. It was beacause there was a method in a Bean Interface which did not have an implementation in the Bean EJB.
appc just gave a NPE.
The issue came out when i did a weblogic.ejbc.

Custom File Extension for Microsoft Access Text Driver (*.txt, *.csv)

I'm trying to use a custom file extension for the Microsoft Access Text Driver (*.txt, *.csv) driver.
I have updated the FileExtns registry to have my new extension.
When I issue the following it does not work.
select [NoName]
from openrowset('MSDASQL'
           ,'Driver={Microsoft Access Text Driver (*.txt, *.csv)};
                DefaultDir=c:\filedir'
           ,'select * from "file.lst"')
If I make the file a .csv it works fine. However, if it has an extension of not CSV or TXT (in this case .lst, which is in the registry setting) extension it throws the following error and cannot seem to find a solution to it.
OLE DB provider "MSDASQL" for linked server "(null)" returned message "[Microsoft][ODBC Text Driver] Cannot update. Database or object is read-only.". Msg 7350, Level 16, State 2, Line 1 Cannot get the column information from
OLE DB provider "MSDASQL" for linked server "(null)".
In addition, (although I can probably find this elsewhere), I need to have the first line 'BLANK' so that it does not miss data (there is no header row). Is there a way to use OPENROWSET without BULK to basically include all rows as data?
Any help is appreciated.

Hi,
According to your description, I did a test with your script, and got the same message as your post. Usually, by default, the Microsoft Access Text Driver (*.txt, *.csv) supports the four extensions file, such as *.asc, *.csv, *.tab, *.txt. To solve this issue,
I recommend you try to save the LST file in the above format, then use OPENROESET to get data from the supported extensions file in SQL Server.
In addition, the
OPENROWSET function is mainly used to retrieve remote data from an OLEDB data source, when you use OPENROWSET without BULK, provider_name is a necessary parameter in the script. However, the OPENROWSET (BULK...) is mainly called from a SELECT…FROM clause
within an INSERT statement, when importing bulk data from a data file into SQL Server table. Thus if you need to import bulk data, you should use the basic syntax: INSERT ... SELECT * FROM OPENROWSET(BULK...), also there are some alternatives, such as
BULK INSERT
and
BCP .

Can Firefox CS5 recognize custom file extensions as PNGs?

WHen you work with game skins you will have custom file extensions such as .scworld and .scskin that are really PNG files renamed. Does anyone know how to add these as recognizeable extensions in Firefox?

no, i am still dealing with this problem on both macs,
mac pro mid 2010 2,8 quad (24GB RAM) and my mbp 15" i7 (4GB RAM)
where i installed Photoshop CS5.
on both macs, photoshop always saves files with capital letter file extensions (xxx.TIF or xxx.PSD)
thats very annoying, as i have to manually rename the file in the finder later.
and thats for all files i create.
i really wonder, could anyone from the adobe staff please comment if it is a bug
or anything else?
thanks!

Adding a custom rendering extension to SQL Server Reporting Services 2012 for SharePoint 2010 integrated mode

We are attempting to add OfficeWriter report rendering extensions for SSRS 2012 in SharePoint (2010) integrated mode through powershell. The documentation for “New-SPRSExtension” is rather
sparse and we have not found any clear examples on the internet. With SSRS 2012 in native mode, we make the following two changes to the config files:
We add the following report rendering extension declaration to
RSReportServer.config:
<Configuration>
    <Extensions>
<Render>
<Extension Name="XLTemplate" Type="SoftArtisans.OfficeWriter.ReportingServices.ExcelTemplateRenderer,
SoftArtisans.OfficeWriter.RS2008"/>
<Extension Name="WordTemplate" Type="SoftArtisans.OfficeWriter.ReportingServices.WordTemplateRenderer,
SoftArtisans.OfficeWriter.RS2008"/>
</Render>
    </Extensions>
</Configuration>
We add the following security trust codegroup to
RSSvrPolicy.config:
<configuration>
    <mscorlib>
<security>
<policy>
<PolicyLevel version="1">
  <CodeGroup version="1" PermissionSetName="Nothing">
  <CodeGroup
                          version="*"
                          PermissionSetName="FullTrust"
                          Name="SoftArtisans_OfficeWriter_Strong_Name"
                          Description="This
code group grants SoftArtisans OfficeWriter code full trust.">
                      <IMembershipCondition
                          class="StrongNameMembershipCondition"
      version="*"
      PublicKeyBlob="00240000048000009400000006020000002400005253413100040000010001004779CB207F11

</CodeGroup>
</CodeGroup>
</PolicyLevel>
    </policy>
</security>
</mscorlib>
</configuration>
What would be the equivalent syntax for “New-SPRSExtension” to do the above for SSRS 2012 in SharePoint (2010) integrated mode?
Alison Bird SoftArtisans Technical Services www.softartisans.com

Hi Alison,
Unlike the deployment of other custom extensions such as custom delivery extension and data processing extension, it is not necessary to add a code group for the custom assembly that grants FullTrust permission for the extension during the deployment of
custom rendering extension. If you have copy the custom assembly to the %ProgramFiles%\Microsoft SQL Server\MSRS11.<InstanceName>\Reporting Services\ReportServer\Bin folder, and modify the RSreportserver.config file to add the extention entry properly,
please open the SSRS Service Application created on the SharePoint and verify that your extension is included in the list of available export types for a report.

Custom rendering extensions not working in SSRS Report Designer (rsreportdesigner.config)

My custom rendering extension is working in Report Builder (in RSReportServer.config), but not in Report Designer (in RSReportDesigner.config): instead of adding a "TXT" export option, it's just adding a duplicate "CSV" option.
SUMMARY:
Is there a way to get these features working, with Report Designer?
DETAILS:
We are running SSRS (Reporting Services) under SQL Server 2008 R2.
Here's my rendering section:
    <Render>
      <Extension Name="XML" Type="Microsoft.ReportingServices.Rendering.DataRenderer.XmlDataReport,Microsoft.ReportingServices.DataRendering" />
      <Extension Name="CSV" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering" />
      
      <Extension Name="TXT" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering">
       <OverrideNames>
           <Name Language="en-US">TXT(ASCII,NoColHds)</Name>
       </OverrideNames>
       <Configuration>
          <DeviceInfo>
              <FileExtension>txt</FileExtension>
               <FieldDelimiter>,</FieldDelimiter>
               <Encoding>ASCII</Encoding>
               <NoHeader>true</NoHeader>
           </DeviceInfo>
       </Configuration>
      </Extension>
      <Extension Name="IMAGE" Type="Microsoft.ReportingServices.Rendering.ImageRenderer.ImageRenderer,Microsoft.ReportingServices.ImageRendering" />
      <Extension Name="PDF" Type="Microsoft.ReportingServices.Rendering.ImageRenderer.PDFRenderer,Microsoft.ReportingServices.ImageRendering" />
      <Extension Name="HTML4.0" Type="Microsoft.ReportingServices.Rendering.HtmlRenderer.Html40RenderingExtension,Microsoft.ReportingServices.HtmlRendering" Visible="false" />
      <Extension Name="MHTML" Type="Microsoft.ReportingServices.Rendering.HtmlRenderer.MHtmlRenderingExtension,Microsoft.ReportingServices.HtmlRendering" />
      <Extension Name="RPL" Type="Microsoft.ReportingServices.Rendering.RPLRendering.RPLRenderer,Microsoft.ReportingServices.RPLRendering" Visible="false" />
      <Extension Name="EXCEL" Type="Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer,Microsoft.ReportingServices.ExcelRendering" />
      <Extension Name="WORD" Type="Microsoft.ReportingServices.Rendering.WordRenderer.WordDocumentRenderer,Microsoft.ReportingServices.WordRendering" />
    </Render>
When I add the above "TXT" section to RSReportServer.config, then Report Builder (and production) both show an export option "TXT(ASCII,NoColHds)".
But when I add this "TXT" section to RSReportDesigner.config, and then (in Report Designer / BIDS) attempt to export from a "Preview" of the report, the export drop-down does not show a "CSV" option followed by a "TXT"
option, but instead shows the "CSV" option twice.
This simply limits testing of the export option, to Report Builder... or requires any reports be published from Report Designer before they can be tested with
this export option.
(FYI, why this export option: compliance in our industry requires sending data to government agencies, in text files, with fixed-length columns, and ASCII encoding. Also, we're attempting to give the production of these files to the *users* managing
communication with those agencies... so we're putting them into SSRS.
I worked around the fixed length columns (and no delimiters -- no commas), by writing a version of the report where all string columns are padded, and all columns are concatenated, to form ONE LONG COLUMN... but Reporting Services' CSV export format produces
a Unicode file (UTF-8, which the agency rejected, because it had a leading "ï»¿", or "EF BB BF" in hex), whereas the agency requires an ASCII file.)

Hi Doug_atMidway,
According to your description, you want to enable your custom render extension. Right?
In Reporting Services, if you want to deploy the custom extension, you just need to add the extension into rsreportserver.config file. The
RSReportDesigner.config file stores settings about the rendering extensions available to Report Designer. Since you still use the csv rendering extension in your assembly, we don't need to do any modification in rsreportdesigner.config file. Pleaes
refer to the links below:
Thanks for attempting to help, Simon.
As my question states, I've *already done* both the above: changed (1) rsreportserver.config and (2) rsreportdesigner.config. I added the same code, shown above, to both files. I did that so I could see the new "txt" extension
both (1) when exporting in production and Report Builder, and (2) when exporting in Report Designer's "preview".
The change in (2) is not working: I do not see the "TXT" extension in Report Designer, when I try to export from a preview. Instead, Report Designer shows the CSV extension repeated.
Thanks for the docs. I consulted them (well, I consulted the EQUIVALENT pages, for SQL Server 2008 R2), when creating my block of code above.
Do you see anything to correct, in my code?
Are the features I'm using actually working, with rsreportdesigner.config?
Thanks again,
-- Doug

How to pass custom cookie from report builder application to SSRS Custom Security Extension?

We want to implement SSRS in SaaS model. We implemented Custom Security extension in order to authenticate users from other application. When user enters username/password, i would like to authenticate the user in other application and it will return some data which can be used for autherization. I am expecting the same set of data will be accessible during all autherization calls.
Currently we are implementing this in Report Builder application. I couldn't able to persist the information in cookie. Report builder removes all the cookies exceprt one cookie which is used by report server.Is there any way to share the information in all reportbuilder autherization calls in same session?

if you have your own data extension, you can using
HttpContext.Current.Application.Add("yourkey",
yourdata);
to save your data, but the issue I met it the key, I cannot find a key depended on report builder. If I use username, if the user open 2 report builder, both of them will get the same key and same data, but at this case the data should be different.
I hope it will help you.

Custom Metadata Extension with RFC call

Hi all,
I am trying to create a custom metadata extension that pulls data from ECC via an RFC call and returns values as a IMetaValueList in the getAllowedValues method.
Does anybody have any experience?
Thx

Hello Sanjeev,
- I Kept External break point in SRM where we are calling RFC Call for ECC, I am able to debug untill the RFC call,
- But, on RFC Call ( CALL FUNCTION ZABC destination <Destination>), when I press F5 it is not going inside the function module.
- I am getting Export parameter values, means ctrl is going to ECC, but not able to debugg our BE system -ECC.
Pls suggest. Thanks for your quick reply.

JDeveloper and UML

Hi,
I'm new to JDeveloper and UML and I'm wondering if the following is possible or even makes sense.
Is it possible to link or "drill down" from a Use Case Diagram into a Class Diagram? I like the way I can publish a Use Case Diagram to HTML and it would be nice to start at this high level and then click down into the specific details of a Class Diagram.
If I'm being too naive in my understanding of the relationship between these different UML levels, please let me know. Otherwise, if it is possible to link Use Case Diagrams w/ Class Diagrams, I would appreciate someone pointing me to a link.
Thanks,
Alan

Hi Guus,
What I was thinking of was something like the following:
On my Use Case diagram, I have the following. An actor symbol (named User) and two Use Case symbols. The first Use Case Symbol is called "Creates Tax Record" and the second is called "Applies Tax to Vendor".
What I would like to then to, is define a link on the "Creates Tax Record" use case that would drill down to a "Tax Record" Class Diagram. That diagram would then have the classes necessary to define a tax record.
So then when I publish the Use Case and Class Diagrams, I could click on the "Creates Tax Record" use case and read the scenario and other information. I would also be able to click on the link to see what the class diagram looked like for that particular use case.
So it sounds like I would need this "semantic locking" to be available somewhere on the Use Case information page. Am misunderstanding something about UML diagrams? Should there be a clear separation between the Use Case diagram and the Class diagram(s)?
Thanks.
Alan

Patch 7315332 - 10G Jdeveloper with OA Extension ARU for R12.1

Hi,
I would have a look at the JDeveloper with OA Extension ARU for R12.1 (cause we will upgrade to R12.1), just to see the features and try to open "old" projects created with the patch 6739235 (11i).
Do you know where I can download a trial version?
Thanks a lot,
Rosanna.

Rosanna,
Should be the same place you get the other patches - "My Oracle Support" - the site formerly known as Metalink.
You would have more luck getting appropriate answers on the OA Framework Forum as well.

Opening BATCH file through custom file extension

I have a situation where I've created my own filetype (.gme) to open my main java file. Each filetype has a corresponding ID which tells the application what instance of it to load. I want the file type to open a batch file which will in turn open the application. Is there code that I can give a custom file extension to open a batch file?

Check the permissions of that batch file.
It should be executable for the PI user (<sid>adm in Unix)

Custom BSP Extension

Hi to all,
I need to have one more attribute in button element for selecting picture for displaying on it.
For this I made a copy of htmlb button element into custom bsp extension,
and copied CL_HTMLB_BUTTON into ZCL_HTMLB_BUTTON, but I am getting some error while activating this.
Please suggest me some way to make this happen.
Regards,

                    encode        = "FALSE" />
I had seen following code to make icons, now if I have lot of icons to make I need write this code several times,
If I write one method of mine application class using above code and use one parameter to change icon name. will it work??
