How to configure Hybris Server to use Oracle Data Base

How to configure Hybris Server to use Oracle Data Base

The following steps can be followed to configure the Hybris server to use Oracle database.

Configure database user:

Login to Oracle database and create the required user and provide the grants.
create user <username> identified by <password> default tablespace <table space name> temporary tablespace <table space name>;
grant connect, resource to <username>;

Configure Hybris server

Copy the oracle driver (e.g. ojdbc6.jar) to /hybris/bin/platform/lib/dbdriver

Go to /hybris/config and edit local.properties by adding the following:
db.url=jdbc:oracle:thin:Username/password//servername:port-id/database name
db.driver=oracle.jdbc.OracleDriver
db.username=xxxxxxx
db.password=xxxxxxx

Verify the configuration details and initialize

Access the Hybris server URL and check the following details:
                   a) Database Name displayed
                   b) User name Displayed
                   c) Database Driver Displayed.
                   d) Check for the default objects (e.g. product, cart etc) already selected.

Click on initialize button on the top of the page. It will take some time and initialize all the tables, table spaces and schemas required.

After successful completion of initialization the server gets automatically restarted, or else it will display errors which need to be rectified.

Configuring proxy server details for HttpClient communication in Adobe Experience Manager(AEM)

Configuring proxy server details for HttpClient communication in Adobe Experience Manager(AEM)

This post will explain how to configure proxy server details for HttpClient communication in Adobe Experience Manager(AEM)

Go to config manager - http://localhot:4502/system/console/configMgr
Open Day Commons HTTP Client 3.1 and provide the proxy server details.


Check "Enable HTTP Proxy" and provide the HTTP Proxy Host and Port details.
If authentication required provide the proxy server user name and password.

Provide the host name and ip address for which the proxy is not required.

This proxy details will be used for all the communication happens via Apache HTTP commons. Client

Invoking NTLM authentication enabled service through Java

Invoking NTLM authentication enabled service through Java

Java API

The below program help us to invoke NTLM authentication enabled services.

public class NTLMAuthentication {

public String invokeService(String url, String soapMessage) {
String responseString = null;
try {

HttpClient client = new HttpClient();
PostMethod postMethod = new PostMethod(url);
postMethod.setRequestEntity(new StringRequestEntity(soapMessage,"text/xml","utf-8"));
postMethod.setRequestHeader("SOAPAction", "http://www.service.com/GetEmployeeData");
postMethod.setRequestHeader("Content-Type", "text/xml; charset=UTF-8");
NTCredentials credentials = new NTCredentials("username","password", "hostName", "domain");
client.getState().setCredentials(new AuthScope(null, -1, null), credentials);
int status = client.executeMethod(postMethod);
if (status == HttpStatus.SC_OK)
{
responseString = postMethod.getResponseBodyAsString();
}
} catch (Exception e) {

}
return responseString;

}
