Tips and Tricks for handling numbers in BPEL or OIC

 While integrating with multiple systems and moving data from one system to the other, we generally come across scenarios, wherein we need to change the format of the number or perform operations like floor, ceil, round, divide, multiply, add, etc. on numbers. We will be going through various mathematical functions available in XSLT 1.0, which would be helpful in such scenarios, and also some generic errors which we encounter usually. - Mathematical Operations Divide Multiply Add Subtract Square-root Round Floor Ceil Advanced Number formatting - Common Errors Mathematical Operations 1. Divide To divide 2 numbers, we can use the  div operator to divide two numbers. Syntax:        $num1 div $num2 Example:        Let us assume we want to divide 120 by 7. XSL: <divide><xsl:value-of select="120 div 7"/></divide> Output <divide>17.14285714285714285714</divide>

Reading .csv files with and without headers using different delimiters in Mule 4

Image
Flat files especially .csv files are very common for data loading and data transfers. We generally come across scenarios where we want to read a .csv file, which may or may not contain the header row. Also, there is a chance .csv files don't have ','(comma) as delimiter rather has ''|"(pipe) as a delimiter or any other character as a delimiter. This article will discuss various ways to read such files in Mule 4 and create a JSON output of it. Mule Flow This will be a simple flow, where we will be reading a file using a file connector. Then convert the read data to JSON using transform message. Finally, log the JSON payload to the console using Logger. Here, we are not doing any complex transformation, it will be more like a MIME type conversion from application/csv to application/json, for better understanding the structure of input data. Steps: Create a flow in your mule application. Drag and drop

DateTime formatting using xp20:format-dateTime ()

xs:dateTime Format In XML, we generally use xs:dateTime(xs:xmlns="http://www.w3.org/2001/XMLSchema") data type to store date time data. The generic representation of date time, that is supported by xs:dateTime in xml: YYYY-MM-DDThh:mm:ss[.SSS][Z|(+|-)hh:mm] Example :  2019-09-11T10:16:31.943+05:30 Code Description Example YYYY represents a 4-digit year 2019 MM represents a 2-digit month 09 DD represents 2-digit date 11 hh represents 2-digit hours 10 mm represents minutes in 2-digits 16 ss represents seconds in 2-digits 31 SSS represents milliseconds 943 T represents time separator T Z represents UTC time zone or 0 time zone offset (+|-)hh:mm represents time zone offset +5:30 Few more valid examples : 2019-09-11T21:32:52, 2019-09-11T21:32:52+02:

Create Delimited String from XML Nodes and Vice Versa in SOA 12c

A delimited string is a string representation of data separated by a delimiter(e.g. ","). A simple representation of the delimited string will look like. Delimited String Examples Sample-1-- Delimiter as ","        Value1,Value2,Value3   Sample-2-- Delimiter as "|"        Value1|Value2|Value3 If we want to represent the above set of delimited values in the form of an XML document under some root and parent tag. The representation will look like this. XML Example <root xmlns="http://test.com/sample/xml">   <Values>     <value>Value1</value>     <value>Value2</value>     <value>Value3</value>   </Values> </root> Sometimes we may need to convert values coming in delimited string to an xml document or vice versa. Since delimited string is similar to csv format. We can create

Import and Export MDS artifacts in SOA 12c

Image
Oracle SOA-MDS (Metadata Store) repository can be used to access artifacts that can be shared among various SOA composites. For example, we have one common schema for a business fault that is consumed by various applications. Instead of having a localized copy of that schema file in each SOA composite, we can have it in a centralized repository (SOA-MDS). Another benefit of using SOA-MDS is that we can change the file at runtime and need not redeploy the complete code. While developing SOA composites, we use SOA design-time repository, later these changes can be synced to the SOA servers. In this article, we will discuss 2 ways to sync the artifacts available in the SOA design-time repository and the SOA servers. Establishing the connection to SOA-MDS in Jdeveloper. Using SOA em console or Fusion Middleware control console. Moving a file between SOA composite to SOA design-time MDS repository Let's assume, we created a businessFault.xsd which wi
