Logs not getting generated for Web Service published on Websphere Application Server 8

Question

I am new to web services and have published a web service on my localhost (Websphere Application Server 8).

I am able to consume the web service successfully but not able to find where the logs are getting generated or even the logs are getting generated or not.

I had place log4j.properties file in WebContent/WEB-INF/classes, but this file is file is automatically getting deleted when I am trying to generate WSDL from Java (Steps - Right click on project name --> New --> Web Service --> Select Class).

Files that were generated:

1. deploy.wsdd
2. deploy.wsdd.bak
3. undeploy.wsdd

and some JARs getting added in WebContent/WEB-INF/lib.

After the file was deleted I have copied log4j.properties again to WebContent/WEB-INF/classes and exported the EAR which was deployed on server.

I have already checked logs in folders:

• D:\IBM\WebSphere\AppServer\profiles\cw_profile\logs
• D:\IBM\WebSphere\AppServer\logs\manageprofiles\cw_profile

but no log file was generated.

Main web service -->

//Logger log = Logger.getLogger(GetDemoTicket.class);
Logger log = LogManager.getLogger(GetDemoTicketv2.class);

public GetDemoTicketv2() {
    super();
    // TODO Auto-generated constructor stub
}

@WebMethod
public String getTicket(String serviceName, String actionName, String bodyStr, String userId){

    Date curDate = new Date();

    log.debug("Starting Execution");
    log.info("Service Name is: "+serviceName);
    log.info("Action is: "+actionName);
    log.info("Body: "+bodyStr);
    log.info("User ID is: "+userId);
    log.debug("Execution Done");
    serviceName = "Service name received: "+serviceName+" "+curDate.toString()+"\n";
    actionName = "Action name received: "+actionName+" "+curDate.toString()+"\n";
    bodyStr = "Body string received: "+bodyStr+" "+curDate.toString()+"\n";
    userId = "User ID received: "+userId+" "+curDate.toString()+"\n";
    log.info("Return Values is \n"+serviceName+actionName+bodyStr+userId);
    return serviceName+actionName+bodyStr+userId;
}

/*public static void main(String[] args) {

Answer 1

From the above code snippets - it seems like its missing the logic to load the log4j.properties file, which you should load in the beginning of your program. So please try adding something like:

Properties applicationProp = new Properties();

String applicationPropFilePath = "C:\\log4j.properties";

load( applicationPropFilePath, applicationProp );

/* This method is a cookie-cutter and loads the given properties file to the given handle */
public static void load( String propFilepath, Properties propFileHandle ){
    try {
        InputStream is = new FileInputStream( propFilepath );
        propFileHandle.load( is );
    } catch (FileNotFoundException e) {
        System.out.println(" Unable to locate properties file: " + propFilepath + e ); 
    } catch (IOException e) {
        System.out.println(" IO Error while loading properties file: " + propFilepath + e ); 
    } catch (Exception e) {
        System.out.println(" Some error occurred while loading properties file: " + propFilepath + e ); 
    }
