IHelperBean Class - Predefined SOA Class to set JCA properties in Spring Component

IHelperBean Class - Predefined SOA Class to set JCA properties in Spring Component 


    Most of the Business logic are not simple to achieve in SOA ( BPEL ) or BPM, to make process more faster and simple to maintain Spring approach  can be use. Calling SOA adapter in Spring also simple.

Question ???    

How to set JCA properties in Run Time with out hard coding properties in .JCA  and I know how to use in BPEL , But how to set in Spring ????


IHelper Bean  ( Note don't change any name for IHelper Bean)

Import Statement :
import oracle.soa.platform.component.spring.beans.IHeaderHelperBean;


 private IHeaderHelperBean headerHelper;


Getters and Setters 


    public void setHeaderHelper(IHeaderHelperBean headerHelper) {
        this.headerHelper = headerHelper;
    }

    public IHeaderHelperBean getHeaderHelper() {
        return headerHelper;

    }


Code Logic :


      headerHelper.setHeaderProperty("jca.file.FileName", "TmpBPCL.txt");
      headerHelper.setHeaderProperty("jca.file.Directory", filePath);

Spring.xml

<beans>

  <bean class="com.bcbsri.spring.mapUtil.ClaimProcessor"

        id="CLM030837IpEditsFileBean">

    <property name="headerHelper" ref="headerHelperBean"/>

  </bean>

How to read GB file or more than 10 MB file using File Adapter - SOA - BPEL

How to read GB file or more than 10 MB file using File Adapter - SOA - BPEL


Most of the time in SOA suite have a suitation to handle more than 10 MB of data to read. But SOA file adapter limitation only 10MB beyond that adapter will fail to read input data. Solution to read GB input file also using Chunk Read logic .



Create normal file adapter using - Sync Read option and modify the .jca file completely

.JCA File :

Chunk Size I defined 100 record / chunk

<adapter-config name="ReadFileChunk" adapter="File Adapter" wsdlLocation="ReadFileChunk.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">

  <connection-factory location="eis/FileAdapter"/>
  <endpoint-interaction portType="SynchReadFile_ptt" operation="synchReadFile">
    <interaction-spec className="oracle.tip.adapter.file.outbound.ChunkedInteractionSpec">
      <property name="DeleteFile" value="true"/>
      <property name="PhysicalDirectory" value="D:\Out"/>
      <property name="FileName" value="Krishna.txt."/>
      <property name="ChunkSize" value="100"/>
     </interaction-spec>
  </endpoint-interaction>
</adapter-config>



BPEL Implementation :


Declare default value before while loop logic


 LineNumber=  "1"
 ColumnNumber= "1"
 IsEOF = "false"


<while name="While_ChunkLoop"
               condition="bpws:getVariableData('VarChunkJcaProperties','/ns7:ChunkFileAdapterProp/ns7:IsEOF') ='false'">

Spring Logic IHelper Bean :

             chunkSize = 1000;
             lineNumber = "1";
             columnNumber = "1";
             currentLineCount = 1;
       
            while (currentLineCount <= totalLineCount - 1) {
                currentLineCount = currentLineCount + chunkSize;

normalize-space() - Be Clear where to use in SOA


normalize-space() - Performs remove unwanted spaces in a string . We know that but how it works internally.

Example : "      Hai       User             Weclome     you            "

Input String contains spaces in the front , last and middle also. I want to remove spaces in front,middle and last.

Note : normalize space will remove extra spaces in between words also and put only one character space.

normalize-space("      Hai       User             Weclome     you            ") ;


Ouput :    "Hai User Welcome you"


If you are looking for front and last to remove spaces use 

oraext:right-trim(oreaxt:left-trim("      Hai       User             Weclome     you            "));


Output : "Hai       User             Weclome     you"
