Graphic design of data sourcing XML from a database
Hi allI try to display a histogram with Source such as an XML that is generated from a database using PHP. Some how I get errors... Is it possible to do that... He... If so how should it be done.
This table exists in MYSQL
CREATE TABLE "project1". "bubble_graph")
Varchar (45) 'Product' NOT NULL default ",
int (10) 'delivery' unsigned zerofill NOT NULL,.
int (10) unsigned zerofill NOT NULL ' delay'
) ENGINE = InnoDB DEFAULT CHARSET = latin1;
INSERT INTO bubble_graph VALUES ('IteamA', 20, 2);
INSERT INTO bubble_graph VALUES ('IteamB', 20, 8);
INSERT INTO bubble_graph VALUES ('IteamC', 20, 1);
INSERT INTO bubble_graph VALUES ('IteamD', 20, 6);
INSERT INTO bubble_graph VALUES ('IteamE', 20, 15);
INSERT INTO bubble_graph VALUES ('IteamF', 20, 3);

Consider this, your code is far away. Your idea is fundamentally correct, but take a look at one, I built. This actauly return xml from a database published on a page and access to the page & data using the correct data aggregate query string values. Look closley the code using im to organize the results.
Import the required namespaces var ResolveUrl:String = ""; Initialization function manages the init program ResolveUrl = Application.application.parameters.ResolveUrl; } Valid entries and fires http service var retVal:Boolean = isValidDates (dateStart.text, dateEnd.text); If (retVal == true) {} wService.send (); } else {} Alert.Show ("Please enter dates valid.', 'Invalid Date', Alert.OK"); } } Manages the State switch Events for new reports currentState = "stSalesByDate"; } Date comparison function handles to ensure deadlines are valid var blnIsValid:Boolean = false;
Import mx.controls.Alert;
import mx.validators.DateValidator
private function init (): void {}
private function buildReports (): void {}
currentState = "stSalesResults";
private function newReport (): void {}
private void isValidDates(strStart:String,_strEnd:String):Boolean {}
If (strStart.length == 0 | strEnd.length == 0) {}
blnIsValid = false;
} else {}
blnIsValid = true;
}
return blnIsValid
}

This code is called e4x he treats xml as a native object, search :)

Read configuration data source AM from Java Bean code
Hi experts,
I use Jdev 12.1.3 and I need to read the name of AM Datasource from Java Code, to get a text like "jdbc/nomsourcededonnees.
Is this possible?Thank you very much
Jose.This object has methods getURL(), getUser() and others.
But there is no method as getDataSourceName()
(AFAIK, jdbc connection "knows" nothing about the Data Source)
You can try something like this inside your AppModuleImpl class:
this.getSession () .getEnvironment () .get (Configuration.JDBC_DS_NAME)

Adding a data source XML in Obiee 11 g on Linux
Hi guys, I need your help.
I create a new database in the physical layer as XML.
On the connection pool (named xml_source), I'll put the path to the XML file, inside the datasourse name, with this format: / u01/app/xmltest /.
My test XML file is the following: xml_test.xml, so in the information in the table, I'll put the name of the XML like this: xml_test (without the xml extension)
The issue is when I am issuing the SQL, the displayed error message says:
Query Failed: [nQSError: 64023] cannot access the /u01/app/xmltest\xml_test.xml: no such file or directoryAs you can read in the error message there is a "-" just before the xml file. So Linux is not a '-' but a ' / ', why obiee puts a bad path? How can I 'know' obiee that there is a Linux environment not a Windows?
Thank you in advance.
Sorry for my mistake, but I found a named XML in the physical Table Properties tab. I put the full URL to the file and now I am able to issue sql to her queries. Thank you!

Problems connecting to JDBC data source
We have recently upgraded to JDeveloper 11 g to 10g and flies our applications (primarily the Struts). They are compiled fine, and I am able to create data sources and successfully test the connection to open the data source through the window of Application resources. The problem comes when I try to connect through the application. In Java code, I use a DataSource object to get the connection of InitialContext.lookup ("jdbc/sun_DS1") where the JNDI name is in parentheses. We used to define this connection in JDev 10 g via the file data - sources.xml and it worked very well. Now with 11g and defines the connection to the application, I don't know if I'm missing a step between the creation of the data source and run the application.
The error I get is: javax.naming.NameNotFoundException: while trying to search for "jdbc.sun_DS1" did not find subcontext "jdbc." Solved "; rest the name "jdbc/sun_DS1.

I spent a lot of time reading Oracle help docs and Googling the problem without success.
Help, please.Once you run your application on the WLS console launch (http://localhost:7101/console) and look to see if JDev created a data source for you in WLS.)
You may need to add it manually. -

Issue in economy/recovery of TEXT RICH in/from MySQL database
Hello
I am not able to save rich text (htm tag) to the database. When I save the text content rich in textfield to database, it is saved in plain text format, but not as rich text.
When I select in the table. I'm getting Plain text but not rich.
This could be a variable incompatibility. I traced a content rich text field to a column of type text variable. Please let me know what I do to store rich text mapped to the database.
following commands I used...
CREATE TABLE fordEformTC4
(
eformName VARCHAR (25),
Fr1Value TEXT,
Fr2Value TEXT,
Fr3Value TEXT
);
I'm putting below the content of the column Fr1Value
<? XML version = "1.0" encoding = "UTF-8" ?>
- < TextField1 type of =" text " >- < body xmlns =" http://www.w3.org/1999/xhtml " >- < p style = " margin-top:0pt;margin-bottom:0pt;text-valign:middle;text-align:justify;font-family:'Myriad Pro'; do-size: 10pt; make-weight: bold; text-decoration: no " " >Problem< span style = » police-weight: normal""">to store the text in the database< /span></p>
</body>

When I retrieve the XML from the database, I see clear...

Integration of data from external sources (xml, webservice)
is it possible to supply the content of DPS to an XML (or other data source)?
You cannot directly import XML or other data sources in DPS, however, there are many options for the style of the content into the system. Assuming that you are talking about DPS 2015, all what you need to do is to convert your data to HTML format, then use packaging article HTML tool to generate a .article to the HTML file. This can be a manual or automated process. For example, there are plugins for Wordpress that automate this workflow to make Wordpress posts and ingest them in 2015 of DPS.

Delete zero of the rows from the data source target
Hi all
We have an ODI interface that loads data directly on a DB2/400 data source into an Essbase cube. The routine uses a SQL Server staging area. We are summarizing the source data and transforming before members of the load in Essbase. It is version 10.1.3.5.5 ODI.
We would like to remove the zero lines created after the sum. Is it possible to do so within the same interface? We understood that we could accomplish this by dividing the interface into 2 parts: 1) load the source data in the staging area and 2) load data from the staging area into the target. We wonder if we can take advantage of the existing interface and somehow add a filter to the target data source.
Thanks for your help,
O"I pull out the filter on a column in the data source and then put the content of the declarations AMOUNT and CASE in there?"-Yes. Deepak may be just fine. Is it JDE G/L, a/c balance treatment?

map a java object to data from multiple data sources
We have the requirement that the attributes in a domain class can come from data from multiple data sources. Is TopLink supports this type of mapping? Is it possible to do this mapping in the workbench?
Thank you very much!
Ming-WenTopLink supports a feature of SessionBroker. This allows classes in the same session to come from different sources of data and for the relations between the classes of data sources. It does not allow a single instance of direct data from multiple data sources, but the Forum could have a link with its data in the other data source.
