![]() Log4j is a common tool, used for small to large scale Java/J2EE projects.Working with log4j is nothing but working with classes & interfaces given in 4j.*.This is a Open Source tool given by Apache, for only java projects, to record or write the status of an application at various places.In order to overcome the problems of SOPL statements Log4j came into picture, with Log4j we can store the flow details of our Java/J2EE in a file or databases.It is not possible to store the SOPL messages in a permanent place and these are single threaded model, means these will prints only one by one message on the console screen.Generally SOPL statements are printed on console, so there are temporary messages and when ever the console is closed then automatically the messages are removedfrom the console.While developing Java/J2EE applications, for debugging an application that is to know the status of a java application at its execution time, in general we use statements in the application right…īut we have some disadvantages while using SOPL () statements.
