Multi Parameter Values in Pentaho Report Designer

August 24, 2014, 9:21 pm
$

Hi everbody.
I've a question to ask. I've create custom report UI using Pentaho CDF, I use checkbox to get value that user choose in checkbox for comparison.
The value inside the checkbox is month name:
January February March April Jun
Julai August September November December

In normal SQL statement we will use IN syntax like this:
where month_name in ('January','February','March')

In Report Designer my SQL look like this:
WHERE
month_name in (${month_name})

The problem is when I choose more than 1 month, the report is empty and not show the data. If I choose only 1 month, the report will show up the data.
How to solve this problem?

Hi everyone,
I'm very new to the work enironment and to the pentaho.
My requirement is to have multiple if else conditions in my transformation. I implement it in Formula as

IF (([XXXX] <= 0 ) ; "0";
IF((([XXXX]> 0) && ([XXXX]<= 5000)); "2" ;"5") )

But getting eror as Was expecting one of: ... "(" ... "{" ... "+" ... "-"
How could I overcome it?


Could I use UDJC for this purpose,if so where could I devolop my code?
When I'm searched about UDJC I could not understand anything.

Any help would be greatly appreciated.
Thanks in advance.

Hi I have a kettle Job with a number of sub transformations and jobs. It requires some parametrers to be passed as arguments.
I am trying to call the job from a jsp web page. I tried the following code:

+++++++++++++++++++
A jsp page with a form will get the parameters from the user and from there, i am calling the CallKettleJob() method :


import org.pentaho.di.core.KettleEnvironment;
import org.pentaho.di.core.exception.KettleException;
import org.pentaho.di.core.exception.KettleXMLException;
import org.pentaho.di.job.Job;
import org.pentaho.di.job.JobMeta;

public class CallKettleJob {
String reportDB;
String clientJNDI;
String client;
String fromDate;
String toDate;
String mailto;
String ccto;
String[] parameters = new String[10];

public CallKettleJob (String reportDB,String clientJNDI,String client,String fromDate,String toDate,String mailto,String ccto){
this.reportDB=reportDB;
this.clientJNDI=clientJNDI;
this.client=client;
this.fromDate=fromDate;
this.toDate=toDate;
this.mailto=mailto;
this.ccto=ccto;
}

public void runKettleJob(){
parameters[0]=reportDB;
parameters[1]=clientJNDI;
parameters[2]=client;
parameters[3]=fromDate;
parameters[4]=toDate;
parameters[5]=mailto;
parameters[6]=ccto;

try {
KettleEnvironment.init();
JobMeta jobMeta;

try{
String filename="e_invoice_main.kjb";

jobMeta = new JobMeta(filename,null);

jobMeta.setArguments(parameters);
Job job = new Job(null,jobMeta);
job.start();

job.waitUntilFinished();

if (job.getErrors()!=0) {
System.out.println("Error encountered!");
}
Result result = job.getResult();

} catch (KettleXMLException e1) {
System.out.println("Kettle XML exception");
e1.printStackTrace();
}
} catch (KettleException e2) {
System.out.println("Kettle ENVIRONMENT exception");
e2.printStackTrace();
}


}

}

+++++++++++++++++++
But I am getting this error. All the jar files in Kettle/ data-integration/lib are in the buildpath
org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/pentaho/di/core/exception/KettleXMLException

javax.servlet.http.HttpServlet.service(HttpServlet.java:723)+++++++++++++++++++++

After trying a lot, I swiced from calling job using pentaho java API, and tried calling Kitchen.sh from the webpage using

Runtime rt=Runtime.getRuntime();
String scriptLocation="/kettlescript/";
String arguments="xxx"
Process process=rt.exec("sh "+scriptLocation+"callKitchen.sh "+arguments);

It works. But I want to call the job using the java API. I can do it fine from a java desktop application. Why not in JSP? Do I need to configure something? Please help me out!!

ブラウザでレポートに日本語をつけて保存する時、Chromeでは問題ないのにFireFOXやIEだと日本語確定のエンターキーで保存されてしまう動きをします。
これを解決する方法は　pentaho.xmlに<submit-on-enter-key>false</submit-on-enter-key>という行を追加することです。

Hi, fellows, I have the context above:

1 - before queries looked like to the model: select fields from a left join (
select fields from b
UNION
select fields from c )
where conditions

2 - now, I have to pick data from 2 databases. The query in red from database 1 and the query in green from database 2.
3 - the union were solved using compound queries( UNION)
4 - the union is base for many dashboads. Each dashboard has a diferent condition.

The question is how do I solve the nested query?

Hi people,


I write you because I am using spoon/kettler to connect to Oracle8 via ODBC (JDBC doesn't work but it isn't the problem). The Oracle database is huge and there is a lot of schemes, by default kettler load all schemes and there is too slow (7 minutes) because there is ~400 schemes.


I want to know how I can be filtered schemes in kettler preferences, I want to load only one scheme. I tried setting "PREFERED_SCHEMA_NAME" with my schema name but it doesn't work =(. Any other ideas?


Thanks a lot

How to ensure logging of environment variables occurs?

August 25, 2014, 10:29 am
$

Hello,

I have certain environment variables that I want to have written to a transformation every time the transformation executes.

My main transformation stream reads data from a files and loads it into a database.

I have a parallel stream in the transformation that has only two steps:


  1. Generate Rows
  2. Write to Log


It is in the "Write to Log" step that I write the environment variables to a log.

The problem is the following:

If there is an error in the data on the main stream, the parallel stream that writes to the log file MAY or MAY NOT be executed.
It usually does, but now always. This seems to be random in occurrence.

Is there any way of writing to the log that is ALWAYS ENSURED, regardless of what errors, etc., may occur in the other steps of the transform?

Thanks,
chasse

when no cluster,the job finshed in 43min14s.
then I set th job run in cluster mode,set the socket buffer size is 20000000,set the socket flush interval 50000,it finishd in 47min3s

Incorrect Results in Java program using WEKA.

Hi all,

I'm trying to develop a little programm in Java in which I use cross-validation for different J48 options. For example if I use the data breast-cancer.arff with this parameters in J48 = [-C, 0.25, -M, 2] the result in Java is equal than Weka :

Results
======

Correctly Classified Instances 216 75.5245 %
Incorrectly Classified Instances 70 24.4755 %
Kappa statistic 0.2826
Mean absolute error 0.3676
Root mean squared error 0.4324
Relative absolute error 87.8635 %
Root relative squared error 94.6093 %
Coverage of cases (0.95 level) 100 %
Mean rel. region size (0.95 level) 100 %
Total Number of Instances 286

But on the other hand when the next iteration has this parameters in J48 = [-C, 0.25, -M, 2, -B] I don't get the same result than Weka. I get this result:

Results
======

Correctly Classified Instances 202 70.6294 % (in Weka is 72.08%) :(
Incorrectly Classified Instances 84 29.3706 % (in Weka is 27.972%) :(
Kappa statistic 0.199 // The rest are different too
Mean absolute error 0.3627
Root mean squared error 0.4782
Relative absolute error 86.687 %
Root relative squared error 104.6236 %
Coverage of cases (0.95 level) 94.7552 %
Mean rel. region size (0.95 level) 94.7552 %
Total Number of Instances 286

Here is the Java code:

Instances dataTrain = data.getDataTrain(); // dataTrain from breast-cancer.arff
dataTrain.setClassIndex(dataTrain.numAttributes()-1);

// listOptions[0] = " -C 0.25 -M 2 ";
// listOptions[1] = " -C 0.25 -M 2 -B ";

for(int i=0;i<listOptions.size();i++){

J48 j48 = new J48();
Evaluation evaluation = new Evaluation(dataTrain);

j48.setOptions(weka.core.Utils.splitOptions(listOptions.get(i)));
j48.buildClassifier(dataTrain);

evaluation.crossValidateModel(j48, dataTrain,10 ,new Random(1));
System.out.println(evaluation.toSummaryString("\nResults\n======\n", false));
}

Does anyone know why in the second iteration the result is different than in Weka?

Thanks in advance,

I'm using formula and follows caluculator. I've to do the multiplication between two fields (in which one of the field is from formula step).
So one field of the fild by default becomes datatype as string and other one is integer. When I'm doing multiplication between these two, I set value type as integer then I could not get the required result.

If I use datatype otherthan integer getting error.
What could I do?

Encoding problem with MySQL data

Hi everybody,
i found a little problem on my transformation, when i try to write "Čaplinskas" on mysql, it gets "?aplinskas". I think is a bit strange it does this error only with this, cause it writes "Šveda" good. I tried to change some parameters (found on another post here) of db connection, and i wrote this on it:

defaultFetchSize 500
collation-server utf8_unicode_ci
clientEncoding utf8
userCursorFetch true
characterEncoding utf8

Probabily clientencoding and usercursorfetch are unusefull, but why still i get the character "?" on db? What can i do to fix that problem?
