Register webservices wsdl in OEG through script

In my previous Post blogger Mark O'Neill pointed me to check new version of OEG, which has been shipped with sample scripts. Last weekend i decided to spent some time to digging out these samples. The following a list of sample scripts which ship with the Gateway: - analyse Perform various analysis on configuration - certs Examples working with certificates - io Exporting and importing configuration - publish Publishing new types to the configuration - upgrade Upgrading older versions of configuration - users Examples working with users - ws Working with Webservices and WSDLs It's pretty easy yo run these scripts, for example sh ws\ will show the list of the registered web service. Similarly will register web service wsdl into OEG. I have simply modify the script to register web services wsdl from file, where file contain a list of web service wsdl as follows:
and here is the modified jython script:
Register WSDL in Gateway

from java.util import ArrayList
from deploy import DeployAPI
from esapi import EntityStoreAPI
from import AddWebServiceServletProcessor
from vtrace import Tracer
import common

t = Tracer(Tracer.INFO) # Set trace to info level

dep = DeployAPI(common.gw_deployURL, common.defUserName, common.defPassword)
es = dep.getStore('')

deployLocation = es.get('/[NetService]name=Service/[HTTP]name=Default Services')
wsGroup = es.get('/[WebServiceRepository]name=Web Service Repository/[WebServiceGroup]name=Web Services')

aws = AddWebServiceServletProcessor(
file = open("wsdls.txt", "r")
for line in file.readlines():
 print line
 deploymentPks = ArrayList()
 aws.addWebService(wsGroup, line.strip(), deploymentPks, 60)
 res = dep.setStore(es)
 if res.getStatus() != True:
     t.error("Failed to deploy: " + res.getFailureReason())
     t.error("Failures: "+ Integer.toString(res.getErrorCount())) 


Next step is to register web service and assign some global policy on them. P.S. Thank's to Mark O'Neill for pointing me about new OEG version


Manipulating Oracle Gateway Entity Store with gateway SDK

Oracle Enterprise Gateway (OEG) is built in gateway product from company Vordel to simplify and secure SOA deployments. OEG replaces Oracle web service manager functionality for SOA development. In real life, most of all time we have a lot of services to registered in OWSM or in OEG. Even more, it was not possible to migrate registered services from one node to another on OWSM. When we got plan to migrate from OWSM to OEG, our main aim was to register web services automatically through API. I was very happy, when found OEG provides some SDK to working with registry. Here is the first attempt to working with OEG SDK. We will use maven to build our project. OEG entity store consolidate all the entities and objects uses in the repository, for example all the registered services and policies. Through Entity store you can add, update and delete any entity. In OTN you can find one tutorial to develop a custom policy through OEG SDK. OEG also provide entity explorer to working with entity store, %OEG_HOME%\Win32\bin\esexplorer.bat First we will install all the necessary libraries on maven local repository.
set OEG_HOME=c:/OEG/gateway/system

call mvn install:install-file -DgroupId=com.vordel -DartifactId=client -Dversion=1.0 -Dfile=%OEG_HOME%/lib/client.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=com.vordel -DartifactId=common -Dversion=1.0 -Dfile=%OEG_HOME%/lib/common.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=com.vordel -DartifactId=entityStore -Dversion=1.0 -Dfile=%OEG_HOME%/lib/entityStore.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=org.apache.axis -DartifactId=axis -Dversion=1.0 -Dfile=%OEG_HOME%/lib/modules/axis.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=org.apache.commons -DartifactId=commons-discovery -Dversion=0.2 -Dfile=%OEG_HOME%/lib/modules/commons-discovery-0.2.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=org.apache.commons -DartifactId=commons-logging -Dversion=1.0.4 -Dfile=%OEG_HOME%/lib/modules/commons-logging-1.0.4.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=javax.xml.rpc -DartifactId=jaxrpc -Dversion=1.0 -Dfile=%OEG_HOME%/lib/modules/jaxrpc.jar -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=javax.wsdl -DartifactId=javax.wsdl_api -Dversion=1.6.2 -Dfile=%OEG_HOME%/lib/plugins/javax.wsdl_api_1.6.2.jar -Dpackaging=jar -DgeneratePom=true
rem add also Win32\lib\vjni.lib in your classpath
After running the above script, we will got all the libraries on our maven local repository. For working correctly, we also have to add vjni.dll file on our classpath. For windows we can do it through PATH variable, for linux platform we can use LD_LIBRARY_PATH. Next we have to create a maven project and add all the dependencies on it as follows:
Now we are ready to write some code and manipulate with OEG entity store. Here is our some pseudo code to manipulate entity.
public class EntityStoreFactory {
    private EntityStoreFactory(){};
    public static EntityStore getEntityStore(final String URL, final String userName, final String password) throws EntityStoreException{ efs =;
        efs.registerForURL(URL,, new ArrayList<string>(2){{add(userName); add(password);}});
        return efs.getEntityStoreForURL(URL);
For testing purpose we are using SOAP provider to connect, but it's possible to use another type of provide such as LDAP, DB e.t.c. You can find the configuration file for the entity store factory in the following place %OEG_HOME%\gateway\system\conf\esproviders.xml .Even you can initialize provider as follows^
efs.initializeProviders(new FileInputStream("%OEG_HOME%\\enterprisegateway\\system\\conf\\esproviders.xml"));
through getEntityStore we can get the entityStore and ready to manipulate entity.
public class AddEntity {
    private static Properties props = new Properties();

    public static void main(String[] args) {
        final String url = "http://localhost:8090/configuration/policies";

        System.out.println("Test Vordel ES api");
        EntityStore es = null;
        try {
            es = EntityStoreFactory.getEntityStore(url,"admin","changeme");
            es.connect(url, props);
            // test connection
            ESPK rootESPK =  es.getRootPK();
            System.out.println("Root:"+ rootESPK.toString());
            /** Get the example webservice entity for simplicity, assume we have one web service registered **/
            // get the web services
            ESPK espkBRs = new ESStringPK("DEFAULT_PRIMARY_OracleGateway_6.1.2:1668"); // added through service manager
   entBrs = es.getEntity(espkBRs);
            // add test entity
            ESPK parentPK = new ESStringPK("DEFAULT_PRIMARY_OracleGateway_6.1.2:147");
   newEntity = new; // webservice type
            // add more fields
            // add parent key
            newEntity.setStringField("name", "testby-api");
            Value primaryWsdlValue = new Value();
            newEntity.setReferenceField("primaryWSDL", new ESStringPK("DEFAULT_PRIMARY_OracleGateway_6.1.2:1670"));

            ESPK newAddEspk = es.addEntity(parentPK, newEntity);
            System.out.println("NewEspk:"+ newAddEspk);
            // add more element on it - ex wsdl
            EntityType wsdlEType = new EntityTypeImpl(es, "");
   wsdlEntity = new;
            wsdlEntity.setStringField("uri", "http://localhost:9000/StockQuote?WSDL");
            wsdlEntity.setStringField("wsdl", "http://localhost:9000/StockQuote?WSDL");
            es.addEntity(newAddEspk, wsdlEntity);
            // add Generated circuits
            // get Circuite container for example
            ESPK parentCircuiteCPK = new ESStringPK("DEFAULT_PRIMARY_OracleGateway_6.1.2:1655");
   newCCType = new; // Contained type
            ESPK newCCForTest = es.addEntity(parentCircuiteCPK, newCCType);
            // add filter circuit
        } catch (EntityStoreException e) {
        } finally {
                try {
                } catch (EntityStoreException e) {
Now we can use entity explorer to check our newly created web service entity.
Our newly created web service is not fully configured yet, we have to add circuit policy on it. Next post will describe how to add circuit policy briefly. Happy coding))
