Log4j in JCAPS

Following is the Steps to implementation the log4j in JCAPS

Step 1:
Import the log4j jar file in to your Project by
Right click on the project select - > import then -> file we chose the
-> jar file (log4j) and select import.

Step 2:
Then import the jar file into your JCD where you want to implement the
log4j is by
Click on Import JAR file on JCD console -> Add ->and select the jar
file that had been imported into you project.

Step 3:
Then code import command statement in the JCD.
import org.apache.log4j.*;

Step 4:
Declare the object for the logger before the main method, as below.
static Category logger = Category.getInstance( "" );

Step 5:
In the Main method code specific path and the log4j properties file, as bel
ow.
PropertyConfigurator.configure( "" );

Step 6:
See that you had configured the log4j property file; your log4j should
look like this

log4j.category.jcdManesh=INFO,dest1

log4j.appender.dest1=org.apache.log4j.RollingFileAppender
log4j.appender.dest1.File=C:/Properties/InstJava.log
log4j.appender.dest1.MaxFileSize=10MB
log4j.appender.dest1.MaxBackupIndex=1
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n

Sample implementation of the log4j JCD looks like this

Code:

package Project1;

import org.apache.log4j.*;

public class jcdManesh
{

static Category logger = Category.getInstance( "jcdManesh" );

public com.stc.codegen.util.CollaborationContext collabContext;

public com.stc.codegen.util.TypeConverter typeConverter;

public void receive( com.stc.connector.appconn.file.FileTextMessage inp
ut )
throws Throwable
{
PropertyConfigurator.configure(
"C:/JavaCAPS513/logicalhost/log4j.properties" );
logger.info( ">>>>>> START <<<<<<" ); logger.info( ">>>>>> END <<<<<<" ); } }

Sample log4j.properties for the above JCD looks like this

Code:

log4j.category.jcdManesh=INFO,dest1

log4j.appender.dest1=org.apache.log4j.RollingFileAppender
log4j.appender.dest1.File=C:/Properties/InstJava.log
log4j.appender.dest1.MaxFileSize=10MB
log4j.appender.dest1.MaxBackupIndex=1
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n
