Execute a Java Driver class (with main) from Command prompt in Alfresco project

SG — Sun, 21 Jun 2020 05:26:45 GMT

I need to execute a Java Driver class (with the main method) from the command prompt as. This is a part of the Alfresco project.

D:\java\bin>java -classpath D:\mylib\mycode.jar org.mycode.MyDriver

MyDriver.java in turn uses log4J.

In order to do so, I need to first set log4J in the open command prompt shell, so that I can run the java MyDriver later).

In order to first set log4j, I do as:

D:\java\bin>java -Dlog4j.configurationFile=file:"D:\log4j.properties" -jar D:\mylib\log4j-1.2.17.jar

However, I get an error as:

no main manifest attribute, in D:\mylib\log4j-1.2.17.jar

How should I set up the Log4J properties in the command prompt?

If I hear you right, I did the following:

As a part of troubleshooting, I thought of placing the log4j-1.2.17.jar and log4j.properties in D:\java\bin (and D:\java\bin is also the JAVA_PATH), and then run the code as:

D:\java\bin> java -classpath D:\mylib\mycode.jar org.mycode.MyDriver

I get error as:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logg

at org.mycode.MyDriver.<clinit>(MyDriver.java:30)

Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger

... 1 more

When I unzip the log4j-1.2.17.jar, the org/apache/log4j/Logg

Er indeed exists in the log4j-1.2.17.jar

The line 30 shown above in the error log is the line where the Logger class from Log4J is used in MyDriver.java
