Logs in the routines

param75 — Wed, 28 Mar 2012 15:22:43 GMT

Hi,
I want to log into a java routine. I work with the enterprise edition an my job is in java.
I have a joblet which create the file log with a specific schema (Cf log.png).
How can I write a message in my java routine like a twarn component ?

Thank you,
Carole

Hi Carole
I don't know what's your routine like.
But you can add these code in tJava or your routine.

resumeUtil.addLog("USER_DEF_LOG", "NODE:tWarn_1", "", Thread
						.currentThread().getId()
						+ "", "WARN", "", "this is a warning", "", "");
				tLogCatcher_1.addMessage("tWarn", "tWarn_1", 4,
						"this is a warning", 42);
				tLogCatcher_1Process(globalMap);
				globalMap.put("tWarn_1_WARN_MESSAGES", "this is a warning");
				globalMap.put("tWarn_1_WARN_PRIORITY", 4);
				globalMap.put("tWarn_1_WARN_CODE", 42);

One more thing. The unique name of tLogCatcher can't be changed automatically(e.g. tLogCatcher_2).
But always it is tLogCatcher_1.

Hi Pedro,
Thank you for the answer. I put it in my routine but I have declarations problem.
resumeUtil : can't be resolved
tLogCatcher_1 : can't be resolved
globalMap : can't be resolved as a variable
globalMap : can't be resolved
globalMap : can't be resolved
globalMap : can't be resolved
The routine doesn't have a lot of code. I verify the length of a field and I reset it with empty value if it's > 4000.
I want to log when I reset the field.

Carole

Hi
If you want to define a perfect method, we need to use Java reflection, which will make it so complicated.
Here is a custom routine for your requirement in a simple way.

package routines;
import routines.system.LogCatcherUtils;
import routines.system.ResumeUtil;
public class field_too_long {
    /**
     * helloExample: not return value, only print "hello" + message.
     * 
     * 
     * {talendTypes} String
     * 
     * {Category} User Defined
     * 
     * {param} string("world") input: The string need to be printed.
     * {param} LogCatcherUtils(tLogCatcher_1) input
     * {param} Map(globalMap) input
     * {param} ResumeUtil(resumeUtil) input
     * 
     * {example} helloExemple("world") # hello world !.
     */
    public static String String_too_long(String field, LogCatcherUtils tLogCatcher_1,final java.util.Map<String, Object> globalMap,ResumeUtil resumeUtil) {
    	String new_field = field;
    	String tmp = "";
    	tmp = field.replaceAll(" +", " ");
    	new_field = tmp.replaceAll("\t+", "\t");
    	if(new_field.length()>3){    //You can change it to 4000.
    	resumeUtil.addLog("USER_DEF_LOG", "NODE:tWarn_1", "", Thread
                .currentThread().getId()
                + "", "WARN", "", "this is a warning", "", "");
        tLogCatcher_1.addMessage("tWarn", "tWarn_1", 4,
                "this is a warning", 42);
    	}
        return new_field;
    }	
}

Pedro

Hi,
I still have errors of compilation. It's certainly due to the using of joblet.
In my tmap, i had put :
too_long.field_too_long(row1.Column1,tLogCatcher_1,globalMap,resumeUtil);
tLogCatcher_1Process(globalMap)
Is it good ? Have I to don't use joblet for the log ?

Carole

Hi,
I get the same trouble here. When not using tLogCatcher_1Process(globalMap) in the routine, it seems the log is not pushed to the tLogCatcher. But when I try to add it to the routine, I get a compilation error :

The method tLogCatcher_1Process(Map<String,Object>) is undefined for the type MyClass
Thank you in advance for your help.
