Implement External Logger Object

User can create own custom logger object by implementing the IngrianLogService interface.

public interface IngrianLogService {
public void info(String message);
public void trace(String message);
public void debug(String message);
public void debug(String message,Throwable t);
public void error(String message);
public void error(String message,Throwable t);
public void warn(String message);
public void warn(String message,Throwable t);
. . .
}

Set the above created logger object on application level as below:

Security.addProvider (new IngrianProvider(new CustomLogger()))

Here, CustomLogger object implements all the common logging methods such as debug, info, trace, and error of IngrianLogService interface.

How to use external logger object

The following steps describe how to upgrade the existing log4j jar files or how to use any other logging framework jar files:

1. Remove the existing log4j jar files (log4j-core-2.17.2.jar and log4j-api-2.17.2.jar) from the classpath.

2. Add the new logger framework jar files and the implementation of the external logger object in the classpath. For example, to use slf4j as external logger, add the following slf4j logging framework jar files in the classpath:

   • slf4j-simple-1.7.9.jar

   • slf4j-api-1.7.9.jar

   • logback-core-1.2.3.jar

   • logback-classic-1.2.3.jar

3. Pass the custom logger object to the Ingrian Provider:

       Security.addProvider (new IngrianProvider(new CustomLogger()))
