[OSB 12c][Tutorial] OSB 12c SOAP webservice for temperature conversion i.e. Celsius to Fahrenheit and vice versa

Image
This tutorial is intended for the audience who are completely new to OSB and want to try a simple hello world kind of application. Instead of sending and receiving Hello World! . We will be using simple temperature conversion i.e. from Celsius to Fahrenheit and vice versa. We will be using simple Xquery to do all conversion and logic. High Level: In this case, our OSB component will contain 2 parts proxy service and pipeline. Proxy service will expose SOAP endpoint to the client application and pipeline will perform various operations on input payload. Since this is just a Hello World application, we will not be using business services. XQuery will be used to implement mathematical logic and conditional logic. Service will take temperature as input and will perform either Fahrenheit to Celsius (FtoC) or Celsius to Fahrenheit (CtoF) temperature conversion. If the conversion type is invalid, then the service will return a failure status. Mathematical Calculations: Let temperature in Fahr...

XML to String and String to XML conversion

Use Cases Many a times, we may need to convert xml data and pass it as a string inside an XML tag. Sometimes from source, we get data which is in string format but actually is xml encoded in string format. To do so in Oracle BPEL 12c or OSB 12c we can use built in functions. XML data to String Sample input <inRoot>     <t1> Hello </t1>     <t2> World </t2>     <t3> One </t3> </inRoot> Sample output <outRoot>    <t1> &lt;inRoot&gt;&lt;t1&gt;Hello&lt;/t1&gt;&lt;t2&gt;World&lt;/t2&gt;&lt;t3&gt;One&lt;/t3&gt;&lt;/inRoot&gt; </t1> </outRoot> XSLT This can be accomplished by using the function  oraext:get-content-as-string(element as node-set) . This function is really helpful when we are working on BPEL as we can use this function in ASSIGN activity or in TRANSFORM activity using XSLT . xmlns:oraext ="http://...

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 strin...

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...
