SQL Developer extensions : Help required regarding reports

Hi,
We are developing an extension for SQL Developer which is similar to reports . So , I need some information regarding the APIs related to report output.
I need to access the resultset of the query output of a User Defined report so that we can customize our extension for some specific requirements. Is there a way to access the resultset after the query gets executed ? Or Are there any APIs where I can look into for some understanding of the background process which happens after the query execution and before the output gets printed on the output window.
Any help or suggestions on this is highly appreciated.

Please do not duplicate threads. No answer means nobody can or wants to help.
At most you can bump the first thread in case someone missed it.
Thanks,

  • Urgent help required regarding reports Arabic Characters (Right to Left)

    Hello Members
    I am facing problem while deploying oracle reports on application server (Forms & Reports). I am using Developer Suite 10g 10.1.2.0.2 and same version of Application Server on Windows Environment. I have some fields in Arabic and some are in English. The reports output is in PDF format. I am also using PDF Subset fonts feature to subset the Arabic font problem.
    Now the problem which I cannot is that I wanted that PDF generate report read Right to Left only for some specific fields not all fields. For example the following fields displayed as
    395/دمام (Actually reading left to right and same saved in database)
    But I wanted to be numbers are displayed first and then arabic word (dammam) while reading right to left.
    My NLS_settings on developer suite and application server is “AMERICAN_AMERICA.AR8MSWIN1256”
    When I am changing the nls_settings to “ARABIC_SAUDI ARABIA.AR8MSWIN1256”. It convert the whole report layout from righ to left and then it is not reading well the English fields i.e. left to right.

    The problem was solved by changing
    REPORTS_BIDI_ALGORITHM=UNICODE
    REPORTS_ARABIC_NUMERAL=ARABIC
    But now i have another issue that i wanted to display one filed with REPORTS_ARABIC_NUMERAL=ARABIC and second with REPORTS_ARABIC_NUMERAL=HINDI. During my all search i found that this is applied on Report wise and we cannot set for one filed.
    Would any body will help me to change REPORTS_ARABIC_NUMERAL for one field at runtime or design time either changing the registry value or any configuration file of application server ?

  • SQL Developer extensions help

    Hey folks!
    So I've been wanting to delve deeper into building user extensions. Have done several google searches and thus far, I've seen only examples of building an extension into the editor tabs on a table object, or creating a context menu. There are other items I'm curious about which I can't find much information on.
    1. Wondering what the 'navigation' user extension does and how to build one?
    2. Also, is there a way to build new buttons along the top under the file menu that will run a specific query upon pushing it or something?
    Anyone have any useful links I can read up on? I'm just having a problem finding anything relating to what these two questions. Thanks in advance!

  • Help required in developing SQL developer extension

    Hi,
    We have a requirement to develop an extension for Sql Developer. The requirement matches the Reports framework in Sql Developer.
    We need to have a separate dock as in reports where we can navigate through the tree and execute some predefined queries.
    I implemented this using the Docking Sample of Sql Developer extensions. I am able to show a separate dock with the tree hieararchy of the nodes and adding context menus to the nodes.
    But , the problem is how do we integrate this UI with the queries and how do we prompt the user to select the connections and other bind variables.
    We can do this by using an XML file and importing it in the reports. But, we need a separate dock for our functionality.
    I tried modifying the reports API by obtaining the code from the oracle.sqldeveloper.report.jar . But , facing problems while compiling the modified code to a jar.
    Any help in this regard is appreciated.

  • SQL Developer extension

    Hello,
    I'm trying to add an extension to SQL Developer. I download manually RDB for SQL Developer extension and then I follow those instructions :
    1 . Click Help menu
    2 . Click Search for updates menu item
    3 . Install from local file and select installer.zip
    4 . Restart SQL Developer
    5 . Add some reports
    I should have an RDB tab in the new connexion window, but it doesn't work. Then I tried another way :
    1 . Click Help menu
    2 . Click Search for updates menu item
    3 . Check all sources (Oracle SQL Developer, Oracle Extensions, Third Party..), next
    4 . Check Oracle Rdb extension for SQL Developer 7.3, next
    In this case I have an error saying something like this :
    An error occured during the updates download
    http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/*null*
    Does anyone has an idea about this problem ?
    Thanks

    You can in the meantime download the extension yourself, instead of using check for updates. This http://www.oracle.com/technetwork/developer-tools/sql-developer/extensions-083825.html is our extensions page. Select the RDB link to take you their downloads page and you'll find the Oracle Rdb Extension for SQL Developer Release 7.3 on that page.

  • Remove (delete) a SQL Developer Extension

    How can I remove the Schema Visualizer from my SQL Developer installation?
    Best Regards
    Niels Jessen

    Tools -> Prefs ->Extensions -> Uncheck the the plug-in you want to disable.
    If you want to remove it from your system, you have to go into your '%SQL_DEV_INSTALL_DIR%\sqldeveloper\extensions' directory and remove the jar files related to that extension.

  • Help debugging SQL Developer extension

    Folks,
    JDeveloper 11.1.1.1.0

    I have a Menu.java class that does this:
    package org.GeoRaptor;
    public class Menu implements Addin {
        public void initialize() {
            // Add context menus
            XMLBasedObjectAction.registerContextMenus(this.getClass().getResource("menu.xml"));
    }menu.xml is loaded as the menus appear correctly when I right-mouse click.
    The class that implements the selected MenuAction is:
    package org.GeoRaptor;
    public class MenuAction extends AbstractMenuAction {
        // Action to do at launch
        private String action;
        @Override
        public void launch() {

  • SQL Developer Extension, GeoRaptor Release 2.1.1 (Build 3) now available

    Cross Post.
    See details at: GeoRaptor Release 2.1.1 (Build 3) Available for SQL Developer
    regards
    Simon Greener

    Hi,
    The original GeoRaptor had some documentation but it has not been updated.
    It is a task on the development list but it has a low priority next to the developments we have planned for the next release. (The main ones being the ability to map the whole, or part, of a SELECT statement executed in a SQL Worksheet - including export to shapefile; the addition of multiple SRID-aware Views to enhance the current single, SRID-unaware view; length/area tools; line and polygon selection tools.)
    The attribute and geometry tabs in the pane in the lower half of the spatial view will appear when an "identify" operation is executed and selected data exists.
    The split into attribute and geometry tabs was done to better control the visualisation experience of a user. The original Geometry tab displayed a single geometry in a non-standard way and allowed a user to drag select ordinates which could then be mapped. The button should have been removed in build 3 but it wasn't. It will probably do nothing. Perhaps in the next release we might replace the button with an ability to select and individual geometry, highlight it and show its points or even show elements in a multi-element geometry eg show me inner ring 2 in the first outer-ring of a multi-polygon. Don't know. If anyone wants this type of functionality register an enhancement request on the sourceforge GeoRaptor website.
    Remember, GeoRaptor is an open source, community driven tool. If you want to help by writing documentation eg a simple one page wiki page on how to validate geometry etc (it doesn't have to be a whole manual), or contribute code, let us know. Or if you simply like the tool or want an enhancement, let us know.
    It is hard writing a tool in the vacuum of one's own experience (no matter how considerable that might be) in a land far, far away (I live in Hobart, Tasmania, Australia), to let us know how we are going......
    regards
    Simon

  • HR SCHEMA FILES PRESENT BUT TABLES NOT SHOWN IN SQL DEVELOPER - PLS HELP

    Dear DBA's,
    I am studying towards the OCA and working through the SQL Fundamentals I Exam guide text book by John Watson and Roopesh Ramklass. I have a problem with accessing the HR Schema tables in SQL Developer. I can get connected to the HR schema but no information is available when i click on the + sign next to the "Tables (filtered)" link in SQL Developer under Human Resources - BTW (I've downloaded Oracle 11G)
    Please help, I've tried the following already;
    1. Downloaded the HR Schema sample scripts again
    2. Resetting the Sample schema with this syntax in SQL PLUS - @?/demo/schema/mksample systempwd syspwd hrpwd oepwd pmpwd ixpwd shpwd bipwd default_tablespace temp_tablespace log_file_directory/
    3. I have no Master script file so I cant recreate the sample scripts
    I've been reading forums and trying to Google but I am too new at this and just can't get the HR schema to display all the information in SQL Developer. Please help as I really badly need to practice the exercises in the text book.
    Any help to resolve this will be greatly appreciated.

  • JAR conflicts in Oracle SQL Developer Extension

    Hi,
    I am developing a extension for Oracle SQL Developer. I want to use JavaFX to show a WebView inside SQLDeveloper, so I imported such library.
    When I try to use such library, the program crashes with an error (NoSuchMethodError) pointing to the constructor of JSObject. The problem is that oracle.help_5.0 (bundled with sql developer) and JavaFX (in the future is going to be bundled in jre) defines the same class (netscape.javascript.JSObject) with different implementations.
    My question is that if it is possible to define/modify the ClassLoader to serve the JSObject provided by JavaFX library to the JavaFX library.
    Thank you in advance!

    Thats odd.
    Do you see any exceptions in console ? (to see the console launch sqldeveloper.exe in ../sqldeveloper/sqldeveloper/bin dir.)

  • New To SQL Developer Data Modeler - Data Dictionary Report

    I am new to Data Modeler and I am currently learning what I can do and can't with it. Is there a way to generate a "Data Dictionary" report? We would like a report we can distribute that describes all tables and columns with descriptions and comments. We used to use an old version of Power Designer and we could do this from the data model we created. Is it possible to do something like this from SQL Developer Datas Modeler?

    Hi,
    Saxon is just an option, you don't need it by default.
    Could be permissions problem. What are you working on i.e. OS? What java version do you use?
    Even though you have specified directory for the reports do you have permissions to write there?
    Report generation directories priority is:
    1. Custom directory if specified in Settings->Data Modeler->Default Reports Directory
    2. /datamodeler/reports/
    3. User home directory
    You must have permissions somewhere on these directories. On the other hand you are saying that report_data.xml is generated so you have permissions.
    Okay. Now I saw a bug in 710. When you click "Generate report" there are progress dialogs and result dialog, but if you meanwhile click somewhere or change focus, these dialogs are hiding below main "Reports" dialog i.e. you are not seeing them. If you use Alt+Tab the result dialog will popup. This bug is fixed in the next release.
    So you must see either result dialog or error dialog at the end of report generation. If not check with Alt+Tab if it is not hidden somewhere below and if there is no such dialog close the DataModeler and check the log file for some error.
    There is SQL Developer Data Modeler 3.3 Early Adopter Available.
    http://www.oracle.com/technetwork/developer-tools/datamodeler/downloads/datamodeler-33-ea-1869055.html
    Above issue is fixed there and report is opening automatically.

  • Oracle SQL Developer Installation Help (Basics?)

    Hello
    So im taking a class (student here, totally new to this) in Oracle SQL right now and trying to download the Oracle SQL Developer tool onto my desktop (v 2.1.1).
    Im just starting up Oracle SQL Developer and its asking, or I am looking to create a connection.
    I was wondering if anyone had a tutorial for how to make a connection?
    I only have Oracle SQL developer installed on my machine right now, nothing else. I dont have a server or anything, and just wanted to run this on my desktop local machine to practice running some SQL.
    Is there anything else i need to install?
    Is there some basic username and password that would allow me to connect to my local machine?
    What values do i need for the hostname, port and SID etc?
    Any help for a new student to Oracle would be greatly appreciated.

    You'd need a database to connect the SQL Developer client to.
    The easiest / quickest if you're a student would be the Express Edition.
    http://www.oracle.com/technetwork/database/express-edition/downloads/index.html
    Pick your platform and away you go.
    Your hostname will then be 127.0.0.1, SID will be XE .... username and password will depend on what you choose when you're installing (you should get prompted for SYS/SYSTEM passwords).

Maybe you are looking for
