Sterling OMS Hot Deployment Weblogic Server

Sterling OMS Hot Deployment Weblogic Server

Sterling OMS Hot Deployment Weblogic Server : After our first post (Sterling OMS Writing First Java Program), one of our well-wisher shared about hot deployment. Yes Hot Deployment really useful to developers. In this post we are going to see how to setup hot development and save time.

Consider below simple scenario

• Customer wants to get organization details using given input XML (Can be in any format)
• Input XML coming into Service looks as shown below

<?xml version="1.0"?>
<Enterprise EnterpriseCode="Matrix" />

• Create java file

package com.oms94.test;

import java.io.StringWriter;

import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;

import com.yantra.yfc.dom.YFCDocument;
import com.yantra.yfs.japi.YFSEnvironment;

public class MapEnterprise {

	/**
	 * Input: <Enterprise EnterpriseCode="Matrix" />
	 * Expected Output : <Organization OrganizationCode="Matrix"/>
	 * 
	 * @param env
	 * @param doc
	 * @return
	 */
	public Document map(YFSEnvironment env, Document doc) {
		if(doc == null) {
			return doc;
		}
		System.out.println("Input : " + getStringFromDocument(doc));
		String enterpriseCode = doc.getDocumentElement().getAttribute("EnterpriseCode");
		YFCDocument  document = YFCDocument.createDocument("Organization");
		document.getDocumentElement().setAttribute("OrganizationCode", enterpriseCode);
		System.out.println("Output : " + getStringFromDocument(document.getDocument()));	
		return document.getDocument();
		
	}
	
	private String getStringFromDocument(Document doc)
	{
	    try
	    {
	       DOMSource domSource = new DOMSource(doc);
	       StringWriter writer = new StringWriter();
	       StreamResult result = new StreamResult(writer);
	       TransformerFactory tf = TransformerFactory.newInstance();
	       Transformer transformer = tf.newTransformer();
	       transformer.transform(domSource, result);
	       return writer.toString();
	    }
	    catch(TransformerException ex) {	      
	       return null;
	    }
	}

	/**
	 * Used For testing only
	 * @param args
	 */
	public static void main(String[] args) {
		MapEnterprise mapEnterprise = new MapEnterprise();
		YFCDocument  inputDocument =  YFCDocument.createDocument("Enterprise");		
		inputDocument.getDocumentElement().setAttribute("EnterpriseCode", "Matrix");
		mapEnterprise.map(null, inputDocument.getDocument());
	}
}

• Final Result XML to call getOrganizationHierarchy API

<Organization OrganizationCode="Matrix" />

Configuration Change Required

• Create new service with name JavaEnterpriseMapTest and Service group name Custom

• Add extended API (From Component section) as shown below and class and method names

• Add Standard API (From Component section) as shown below

• Connect all the points

• Click Save

How to build custom code? (Only Once)

• Go Eclipse Right click on project name SterlingCustom94
• Select Export
• Under Java — Select Jar file
• Select Jar file location <Install Directory>\jar\customjar\1\SterlingCustom94.jar
• Run Command : deployer.cmd -t resourcejar
• Run Command : buildear.cmd -Dappserver=weblogic -Dwarfiles=smcfs,sbc -Dearfile=smcfs.ear -Dnowebservice=true -Ddevmode=true -Dnodocear=true -Dwls-10=true create-ear
• Run Command: del C:\deploy\smcfs.ear (Deleting old ear file)
• copy <Install Directory>\external_deployments\smcfs.ear C:\deploy

How to perform Hot Deployment?

• Extract From C:\deploy\smcfs.ear file into C:\deploy\smcfs.ear folder (One time)
• Extract From C:\deploy\smcfs.ear\smcfs.war file into C:\deploy\smcfs.ear\smcfs.war folder (One time)

• Go Eclipse Right click on project name SterlingCustom94 (Repeat below steps when code change made)
• Select Export
• Under Java — Select Jar file
• Select Jar file location C:\deploy\smcfs.ear\SterlingCustom94.jar
• Complete jar file creation

Weblogic Deployment

1. Login to weblogic console http://localhost:7001/console
2. Deployments link — Using Delete button remove the previous ear (if any)
3. Click Install button
4. Select directory C:\deploy and select smcfs.ear folder (Open Directory)
5. Complete the deployment
6. Make sure application deployed successfully and present in active status

Run the test?

Output

Conclusion

Moving forward you can just make code change and build custom jar file using eclipse export option and just stop and start weblogic server or perform redeploy to test changes.

You are ready for testing.

Note: Deploy and redeploy can be done via command line. Let’s see how to perform auto build and deploy using command line in another post.

Happy Learning!!!
