kandi X-RAY | kettle Summary
Kettle is an integration technology which promotes the expression of servers handling HTTP and WebSockets endpoints. With a few exceptions, Kettle implements no primary functionality of its own, but aggregates the facilities of express and ws, as well as middleware held in the wider pillarjs "Bring your own HTTP Framework Framework" ecosystem. Kettle applications can easily incorporate any express-standard middleware, as well as coexisting with standard express apps targeted at the same node.js http.Server. Since Kettle applications are expressed declaratively, in the JSON format encoding Infusion's component trees, it is possible to adapt existing applications easily, as well as inserting middleware and new handlers anywhere in the pipeline without modifying the original application's code. This makes Kettle suitable for uses where application functionality needs to be deployed flexibly in a variety of different configurations. In fact, Kettle's dependency on express itself is minimal, since the entirety of the Kettle request handling pipeline is packaged as a single piece of express-compatible middleware – Kettle could be deployed against any other consumer of middleware or even a raw node.js HTTP server.

QUESTION
Using Pentaho data integration (Kettle), I read a long string from a text file:
a, 1, 2, b, 3, 4, c, 5, 6, ...
Is there any PDI/Kettle steps or method to split this string to become an n column table format like below (the column name can be define freely):
column1 column2 column3 a 1 2 b 3 4 c 5 6the above just a simplify example, my real case is having different separator character and the column number (n) is bigger. But I just want to get the main problem solve first.
...ANSWER
Answered 2021-Apr-03 at 15:26I didn't understand about "different separator character". If you have different separators on the same line, such as a comma and a semicolon, then this is a tricky task for the PDI process. Then you need to cast all delimiters to the same type first. For example, in Notepad ++, make a replacement. Notepad ++ does a good job with large CSV files.
Further in the PDI there is a standard separator component "Split Fields".
QUESTION
We have a java app that needs to use a public class form a JAR file. After much frustration with the main application, we have created a simple repo here to try to figure out what is going on.
The overly simple file that ends up in the JAR file is as follows:
ANSWER
Answered 2021-Apr-07 at 03:52Before adding the jar to library, you may run the command java -jar printStuff.jar to test if it could be executed successfully.
The error occurs because the class must be called with its fully qualified name. To be clear, the name of this class is not printStuff, It's com.mystuff.helpers.printStuff, so the right command should be:
Turn to the folder;
Compile .java file:
javac com\mystuff\helpers\printStuff.javaGenerate .jar:
jar cvfe printStuff.jar com.mystuff.helpers.printStuff .\
Then readd it to referenced libraries and see if the error goes away.

QUESTION
My database has the following tables:
...ANSWER
Answered 2021-Jan-25 at 16:55You need to read the CSV and the USER table, after those two steps, you need to add a Sort step for each one (check for the case sensitive/insensitive possibilities in the Sort step), afterwards, with a merge join step you merge both streams of data, you set it up as a LEFT OUTER JOIN, on the left the CSV data (coming from the sort step), on the right the USER data (coming from the sort step), so for each username in the CSV you look if the username already exists in the USER table.
Following the MERGE JOIN, you put a Filter step, looking if the userid data IS NULL, if it's NULL, that means that the username in the CSV doesn't exist, so you'll need to insert it first in the USER table.
If you have the userid (filter condition false in the previous step) you can simply insert the data in the USER_SESSION_HISTORY with the userid you retrieved from the MERGE JOIN.
For the true condition in the filter (no previous data in the user data), it's going to depend on how you generate the userid. If you have a sequence associated to the userid, and the column is automatically filled with the corresponding next value of the column, you can insert the username in the USER table and the database will take care of filling the userid. If you can't simply insert the username in the USER table, you'll have to add some intermediate steps to generate the userid depending on how you handle it in the database.
I don't know if after inserting in the USER table you'll be able to see the userid generated, you can test it. If you have it available in this transformation, you can add a block step after the Insert step in the USER table, waiting for the Insert step in the USER_SESSION_HISTORY to finish (for the data where the username was already present in the USER table, the false condition in the filter step). The block step is needed because Pentaho runs all the steps at the same time unless you use this block step, so the USER_SESSION_HISTORY table would be blocked with two transactions executing at the same time. After the block step, you add a second Insert step for the USER_SESSION_HISTORY table.
If you don't have available the userid available after inserting, I think the easier way to work would be with two transformations, first one to insert the new usernames in the USER table, and a second transformation to insert the data in the USER_SESSION_HISTORY, in the second transformation we are sure we already have all the usernames available in the USER table
QUESTION
For my college work, I need to import a list from another python file and then get a value from it. The list goes like Name, Size, Price, VAT Rate. We are not allowed to change the list or import anything other than the python file (which contains loads of other values)
From this list, I need to find the highest value and also return the item name as well as print the value with the added VAT. I thought about finding the highest number value, finding out the percentage (not sure how yet) then going back 2 values to find the name but I'm not sure how to code that. I've looked around for a while and I'm not able to find any solutions. I'd appreciate any help if possible!

...ANSWER
Answered 2020-Dec-17 at 08:55You will need to add the jfxswt.jar file to your classpath for compile and for execution.
This can be done by using the system scope as that jar file is part of your JDK under the jre/lib directory.
