How to create a semi circuler slider using java swing or awt

I am trying to create a Jslider like thing but in semicirculer shape. Thanks in advance for providing any help.

Is it possible to create such UI in java swing?Just to further illustrate, Swing only provides the raw foundation you need to be able to build a GUI. With the stock components you can create static user interfaces with standard controls. If you want to go further, you need to either find a component that somebody else already wrote, or you go into custom painting as previous posters suggested. To do an animating component for example, you would need all the frames as BufferedImage objects and you would combine custom painting with a Swing timer to update the displayed frame at a specified framerate.
if you search for "java swing animation" using google, I'm sure you can find the examples you need. And here is the trail about swing timers:

Hi,
I want to find the installed JREs in windows using java. I couldn't fine any java API. So I am using the below code to fetch the JRE list from windows registries & parse the returned collection to know the installed JRE.Why? If you are running java you already have a JRE. So why not just use it?
>
String key = "HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Runtime Environment";
Runtime.getRuntime().exec(
"reg query " + "\"" + key + "\"");
Is it legal to retrieve the installed JREs in this way? Legal? It is OS specific, and to a certain extent dependent on vendor and what the vendor wants to do. Could also be impacted by permissions. Other than that it is ok.
I am feeling like its a type of hacking. So I couldn't decide whether this is legal (recommended) way of using. Does anybody can answer me. I can see the similar posts in google. Somebody suggests this way & somebody suggests to use preference API which is similar to this. Appreciate your help.Preferences won't work. It doesn't allow access to the registry in general, only a part of it. There are discussions in the JNI forum about retrieving VM versions. Prior to actually using the VM though.

How to create a subreport link programmaticly using java RAS sdk

Hi,
I want to create subreport link for couple of main report parameters programmaticly using RAS sdk.
Main report has Param1 and Param2. I need to link these parameters to sub-report which doesn't have any parameters, so I can pass the parameters value just once when running the report and consume it's value in the sub-report.
Below is the code I tried but I get "Invalid field name"error when I try to save the main report.
ISubreportClientDocument subReportDoc = subReportCntrl
.getSubreport(subReports.getString(i));
SubreportLinks srLinks = subReportCntrl.getSubreportLinks(subReports.getString(i));
SubreportLink subRptLink1 = new SubreportLink();
Fields paramFields = reportClientDoc.getDataDefinition().getParameterFields();
subRptLink1.setMainReportFieldName(paramFields.get(0).toString());
subRptLink1.setSubreportFieldName(paramFields.get(0).toString());
SubreportLink subRptLink2 = new SubreportLink();
subRptLink2.setMainReportFieldName(paramFields.get(1).toString());
subRptLink2.setSubreportFieldName(paramFields.get(1).toString());
srLinks.add(subRptLink1);
srLinks.add(subRptLink2);
subReportCntrl.setSubreportLinks(subReports.getString(i), srLinks);
Thanks,

How to create a stored procedure and use it in Crystal reports

Hi All,
Can anyone explain me how to create a stored procedure and use that stored procedure in Crystal reports. As I have few doubts in this process, It would be great if you can explain me with a small stored proc example.
Thanks in advance.

If you are using MSSQL SERVER then try creating a stored procedure like this
create proc Name
select * from Table
by executing this in sql query analyzer will create a stored procedure that returns all the data from Table
here is the syntax to create SP
Syntax
CREATE PROC [ EDURE ] procedure_name [ ; number ]
    [ { @parameter data_type }
        [ VARYING ] [ = default ] [ OUTPUT ]
    ] [ ,...n ]
[ WITH
    { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]
[ FOR REPLICATION ]
AS sql_statement [ ...n ]
Now Create new report and create new connection to your database and select stored procedure and add it to the report that shows all the columns and you can place the required fields in the report and refresh the report.

Raghavendra

How to create an RDBMS event generator using wlst on weblogic 10.3

how to create an RDBMS event generator using wlst on weblogic 10.3, i got a code fragment needing class "com.bea.wli.management.configuration.RDBMSEventGenChannelConfiguration"
but i can' t find this class in classpath on weblogic 10.3, pls help me, thanks. code sample is better.

Hi,
RDBMS Event Generator Channel Rule Definition
When you are creating channel rule definitions in the WebLogic Integration Administration Console, it is recommended that you do not use the Back button if you want to resubmit the details on a page.
You should always use the navigation links provided and create a new channel rule definition.
http://download.oracle.com/docs/cd/E13214_01/wli/docs85/deploy/cluster.html
http://download.oracle.com/docs/cd/E13214_01/wli/docs81/relnotes/relnotesLimit.html
http://otndnld.oracle.co.jp/document/products/owli/docs10gr3/pdf/deploy.pdf
This problem has been seen in the past when defining the channel rule for an RDBMS Event Generator if schema name was specified with the incorrect case (i.e. lowercase when it should have been uppercase or vice versa). To that end, it is suggested to change the case of the schema when creating the channel rule

How to create hierarchy on bi7 by using dtp

how to create hierarchy on bi7 by using dtp

Hi Deba,
Procedure to create Hierarchies:
1.      In the Data Warehousing Workbench under Modeling, choose the InfoObject tree.
2.      If you have assigned the hierarchy basic characteristic to an InfoObject catalog, select the corresponding InfoObject catalog for an InfoArea.
If the hierarchy basic characteristic does not belong to an InfoObject catalog, choose the InfoArea Non-Assigned Nodes and the InfoObject Catalog Non-Assigned Characteristics.
3.      Select the characteristic for which you want to create a hierarchy and choose Create Hierarchy from the context menu. The Create Hierarchy dialog box appears. The InfoObject name appears by default.
4.      Enter a hierarchy name and description (short, medium, long). Other fields may be displayed, depending on which hierarchy properties were selected for the hierarchy basic characteristics
Fields used to enter the Validity (valid to, valid from) for the hierarchy property Total Hierarchy Time-Dependent
Fields used to specify the Hierarchy Version for the hierarchy property Hierarchies Version-Dependent.
5.      Confirm your entries. The Maintain Hierarchy screen appears. You can define the structure of a hierarchy here.
6.      To create a hierarchy node, you first need to choose an insertion mode: Insert as First Child or   Insert As Next Neighbor (see Hierarchy Editing Functions).
7.      Choose the type of node you want to create: Text Node, Characteristic Node, <Hierarchy Basic Characteristic Node> or Interval (see Hierarchy Nodes)
8.      Repeat this procedure until the hierarchy structure has been set. For more information, see Modeling Nodes and Leaves.
A hierarchy can contain 50,000-100,000 leaves at most. If your hierarchy is larger, you should insert a level that is used as a navigation attribute or preferably as a separate characteristic in the dimension table.
9.      You can use Level Maintenance and Hierarchy Attributes to set how the hierarchy is to be displayed and processed in reporting (see Level Maintenance and Hierarchy Attributes).
10.      Save the hierarchy.
11.      Activate the hierarchy. See Editing Hierarchies.

How to create Profit and loss account using report painter

Dear All,
Can some one guide me as to how to create Profit and loss account using report painter.
If some one can share the document having steps to be done,would be of great help.
Thanks in advance.
Regards,
Gokul

Hi,
Could you please re-phrase your question? As the report painter is a reporting tool I assume you want to report on P&L accounts and not u201Ccreateu201D them. A few more details on what you intend to report would be useful.
