Development of a SearchComponent - How to start?

I am trying to develop Search Component and I have few doubts.
1) finding jar files for development. I am using class locator to find them, but how do I include it? Should I add those jar copy in my par file? Or is the reference enough? Will be picked up from portal location during run time?
2) I am trying to dynamically change the search folder during search. Is this possible?
3) Can Search component be a simple java class or should it be a Portal Component/Service?
Thanks,
Deepak

Hi Deepak,
> 1) finding jar files for development. I am using class locator to find them, but how do I include it?
At build time through the .classpath file, which ClassLocator does for you. At runtime through the (Private)SharingReference reference within portalapp.xml.
> Should I add those jar copy in my par file?
No, never!!!
> Or is the reference enough? Will be picked up from portal location during run time?
Yes. See http://help.sap.com/saphelp_erp2004/helpdata/en/3d/571140d72dc442e10000000a1550b0/frameset.htm and around.
> 2) I am trying to dynamically change the search folder during search. Is this possible?
I'm unsure what you mean exactly, but of course it is possible to define under which folder the search should start. Obviously, as you may allow the end user to pick up such a folder!
> 3) Can Search component be a simple java class or should it be a Portal Component/Service?
It is a class; nevertheless, you need a dummy service within your project which adds your classloader to the CrtClassloaderRegistry.
See https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/41cbcb56-0701-0010-43b4-fbc138ea2b6a for more details; the docu has some bugs, but should be helpful to understand how all things work together.
Hope it helps

    I want to learn card programming.http://developers.sun.com/techtopics/mobility/javacard/articles/
    Read "An Introduction to Java Card Technology" Part 1 to 3 for starting with java cards.
    1) Where can i find an IDE to write program ?The JCOP tools plugin for Eclipse is the cheapest IDE i know.
    http://www.zurich.ibm.com/jcop/products/tools.html
    2) Do we get any simulator in it ?Use CREF from the Java card development Kit or the JCOP emulator from the JCOP tools.
    3) How to compile and run the card program.See the Java Card Development Kit User’s Guide that comes with the Java Card JDK.

  • How to start listener in sql developer for remote debug

    how to start listener in sql developer for remote debug ? Since the new version 1.1.0.23 is different with the old version for remote debug, I don't know how to start the listener on the new version for remote debug.
    even follow the user guide below and not work . Experts on sql developer please help me with this.
    Remote Debugging
    To debug a procedure or function for a connection where the database is on a different host than the one on which you are
    running SQL Developer, you can perform remote debugging.
    Remote debugging involves many of the steps as for local debugging; however, do the
    following before you start the remote debugging: Use an Oracle client such as SQL*Plus to issue the debugger connection command. Whatever
    client you use, make sure that the session which issues the debugger connection commands is the same session which executes your PL/SQL
    program containing the breakpoints.
    For example, if the name of the remote system is remote1, use the following SQL*Plus command to open a
    TCP/IP connection to that system and the port for the JDWP session:
    EXEC DBMS_DEBUG_JDWP.CONNECT_TCP('remote1', '4000'); The first parameter
    is the IP address or host name of the remote system, and the second parameter is the port number on that remote system on which the debugger
    is listening.
    Right-click the connection for the remote database, select Remote Debug, and complete the information in the Debugger - Attach
    to JPDA dialog box. Then, follow the steps that you would for local debugging (for example, see Debugging a PL/SQL Procedure).
    Debugger - Attach to JPDA This dialog box is displayed when you right-click a database connection name and select Remote Debug.
    Use this
    dialog box if you are using the Sun Microsystem's Java Platform Debugger Architecture (JPDA) and you would like the debugger to listen so
    that a debuggee can attach to the debugger.
    For more information about remote debugging, see Remote Debugging.
    Host: Name or IP address of
    the remote host on which SQL Developer should listen for the database to connect.
    Port: Listening port number on the remote host. You can
    choose any valid port number that is not in use by another process.
    Timeout: The number of seconds that SQL Developer will wait for the
    remote database to make a debugging connection. Don't Show Dialog Box Before Connecting: If this option is checked, this dialog box will not
    be displayed before future connections for remote debugging

    You're not the only one:
    Not able to start remote debug listener

    SHUTDOWN is not a SQL statement but a SQL*Plus command . You cannot use SHUTDOWN in PL/SQL.

  • How to start developing Xcelius component?

    Guys,
    When can I find steb-by-step explanation of how to start developing own Xcelsius components or modify existing?
    I performed following actions:
    1) installed Xcelsius 2008 Component SDK SP3
    2) downloaded Flex 2.0.1 SDK from here:
    http://labs.adobe.com/technologies/flex/sdk/flex2sdk.html
    3) installed Flex Builder 3.0
    Now I don't understand what to do...need assistance

    Hi,
    You use the Xcelsius Add-On Packager (comes with the SDK) to create custom add-ons. Within this tool you can define visual components, connections or functions that can be exported as add-ons.
    In order to define a visual component (the most used type) you need to first create two separate swf files. One contains your custom flex component, the other contains the interface (property sheet) the user will be using in Xcelsius to interact with the custom component. 
    1. Custom flex component (swf)
    Develop your custom flex component as you normally do in Flex, Xcelsius SDK is not involved in any way here. Define component styles and public properties that can be later be accessed via the property sheet.
    2. Property sheet (swf)
    It's the interface to your custom component. Here end users can change fonts, colors, bind cell values to component properties, etc. This is possible via the Xcelsius SDK. Using the SDK you get to populate the interface initial values values with the default custom component style and property values. You can also initiate bindings here between component properties and cell values.
    Under C:\Program Files\Business Objects\Xcelsius\SDK you can find both the full documentation and samples to get you started.
    Hope this helps,

  • How to start developing an Enterprise Service

    Hi everybody.
    I'm a student who writes his diploma thesis at the moment.
    My aim is to identify different serivce candidates with the aid of a roadmap methodology in my company. After doing a business process analysis and identifying all the IT systems and interfaces to external systems I want to develop a enterprise (web) service (with ABAP/Java) offering some type of masterdata from SAP HCM and deploy it to the Exchagne Infrastructure of my company.
    But I don't know how to start. There is too much (poor) information. Until know I did not find concrete howto-guides with examples for "developing a service" (both ABAP and Java), "deploying and testing a service with XI". Could somebody give me some hints?
    I have access to the ABAP workbench, XI and the NWDS and have read all the theoretical stuff about SOA and SAP ESOA.
    Thanks in advance,

  • How to start working with a Development Component

    Hi Guys,
    Till now I was working with the local development of WD. I was the only one working so I created a local project and use to deploy to the J2EE Engine.
    Now we have got the full NWDI (Netweaver Dev Infrastructure).
    I want to know exactly how to start working and creating Projects now that the work is not local. I may need to use 1 DC inside another.
    A Development Component is to be created in the CMS and Checked into DTR. From the DTR I check in into my workspace. This is all i know
    Can someone tell me exact steps of how to start the work.
    Thanks for your support

    Hello,
    I believe you have already setup NWDI correctly and its running fine.
    So here is link of a step by step guide.
    http://help.sap.com/saphelp_nw04/helpdata/en/c3/2656405aff1e24e10000000a1550b0/content.htm
    If you want to migrate your existing WD Projects to DC Projects, here is a link for "how to" do the same.
    http://help.sap.com/saphelp_nw04/helpdata/en/9e/1c200ac164cf4a942f2dacdf3359e9/frameset.htm
    If you want to create an external utility library containing some jar files which you want to use in your DC, follow this excellent blog by Valery.

  • How to start sql developer(1.1) on mac osx

    After download and unzip it, just double-click the sqldeveloper icon, doesn't it?
    But after i double-click it, there is an icon on the bottom for a while, very soon. then it disappears.
    Any help will be highly apprecaited!!!

    Hi
    I've got the same error starting SQL Developer 1.1.2 on mac os 10.4.9. In my case this was because I've had a blank in the path.
    I've initialy located my SQL Developer on a USB Stick with the name "no name" which was mounted on /Volumes/no name path to SQL Dev was /Volume/no name/oracle/sqldeveloper/......
    After changing the name of the stick to noname the path has changed to /Volume/noname/oracle/sqldeveloper/.....
    and then everything worked fine.
    An other hint, If you copy sqldeveloper.sh into sqldeveloper.command you may start the Developer with a double click.
    By the way, I'm using the multiplattform package of the SQL Developer and put it on a USB Stick. I'm now able to take one copy of SQL Developer and Configuration with me and start it on Mac OS and/or Windows.

  • How to start with JDeveloper?

    As a straight A student of Computer Science, I put my hands on database development of an information system project for our CS faculty this summer. JDeveloper is used as the IDE for such project.
    I have learnt Java 2 and something about Oracle database in my courses. Now, after reading the product introduction and a short online course outline in iDeveloper2001, I have a brief idea about it. But since I can not afford much, how to learn more about it? Could you offer me some advices?
    Thanks a lot!

    The online users guide and documentation is the best place to
    start to learn how to use JDeveloper.

    Konda,
    Endeca has few different products. Find out which product which version you are using. Then start with 1. Endeca-Concepts Guide, 2. Endeca Getting Started Guide (of your product), 3. Endeca MDEX Engine Basis Developer Guide. After these 3 based on what your requirement is you will be able to figure out which next document to pick.
