QUESTION
I am new in Spring Boot, I am trying to connect to SQL Server in Windows Authentication mode and here is my database configuration:
...ANSWER
Answered 2022-Apr-17 at 23:55I found the solution and it was only to use
integratedSecurity = false;
instead of
integratedSecurity = true;
so in this case connection string will be:
database.name= DatabaseName spring.datasource.url=jdbc:sqlserver://1.2.3.4:11111;DatabaseName=${database.name};integratedSecurity = false;.
Why to use integratedSecurity = false? The reason is here:
"Integrated Security When false, User ID and Password are specified in the connection. When true, the current Windows account credentials are used for authentication."
QUESTION
I am trying to setup simple cluster of 2 ActiveMQ Artemis brokers within Docker Swarm environment.
Stack configuration
...ANSWER
Answered 2022-Mar-18 at 13:53The connector named "netty_connector" shouldn't use 0.0.0.0. This is the address that will be sent to other nodes in the cluster to tell them how to connect back to the node who sent it. The address 0.0.0.0 will be meaningless in that context. It needs to be the actual IP address or hostname where the broker is listening for network connections.

I am trying to pull across data from within over 800 links and putting it onto a table. I have tried using chrome selector gadget but cannot work out how to get it to loop. I must have spent 40 hours and keep getting error codes. I need to pull the same information from li:nth-child(8) , li:nth-child(8) strong and another couple text boxes of information. I have tried following a YouTube video and I just changed the names and links but otherwise maintained consistency and it just will not work.

QUESTION
I'm consuming messages from an ActiveMQ Artemis topic using JMS. My consumers are connecting directly to the FQQN of their consumer queues. Like this:
...ANSWER
Answered 2022-Mar-04 at 16:18It's not possible to configure the broker to auto-create a dead-letter queue whose name contains the name of the queue where the message was originally sent. As noted in the documentation, the dead-letter queue is named according to the address where the message was originally sent along with any configured prefix and/or suffix.
However, the message itself will have a property named _AMQ_ORIG_QUEUE which will contain the name of the queue where the message was originally routed. This means you can use a consumer with a message selector (e.g. _AMQ_ORIG_QUEUE = 'ConsumerA') so that the consumer will only receive messages which were originally routed to a particular queue. This is functionally equivalent to having a dead-letter queue per-queue.
For what it's worth, what you're calling the "consumer name" isn't the name of the consumer at all, at least not from the broker's point of view. It's just the name of the queue.
Ultimately it's just not possible to configure a dead-letter queue per-queue. It's only possible to configure a dead-letter queue per address. This is true whether the resources are create manually (e.g. via broker.xml) or automatically.

QUESTION
I am a bit desperate and I hope someone can help me. A few months ago I installed the eclipse cloud2edge package on a kubernetes cluster by following the installation instructions, creating a persistentVolume and running the helm install command with these options.
...ANSWER
Answered 2022-Feb-09 at 06:58based on the iconic Failed to create SSL Connection output in the logs, I assume that you have run into the dreaded The demo certificates included in the Hono chart have expired problem.
The Cloud2Edge package chart is being updated currently (https://github.com/eclipse/packages/pull/337) with the most recent version of the Ditto and Hono charts (which includes fresh certificates that are valid for two more years to come). As soon as that PR is merged and the Eclipse Packages chart repository has been rebuilt, you should be able to do a helm repo update and then (hopefully) succesfully install the c2e package.
QUESTION
I am trying to understand how ActiveMQ Artemis manages the journal files (under data/journal) and when it creates new ones. I read the documentation, but it wasn't clear how the files are create. I have a broker.xml has simple settings (won't be able to share unfortunately). Here are a few:
- journal min threads - 2
- journal pool size - 50
- file size is defaulted to 10MB.
ActiveMQ Artemis starts, and I see 2 files are already created under /data/journal. I am now running a request that posts a lot of messages in a very short time. These messages are being actively consumed. I am publishing a lot of messages but they are not accumulating as fast because the consumer is consuming them. However, this doesn't cause the files to grow to recreate the space issue.
As the message volume is going up I don't see the number of files going up. It goes up and stays at 12 files for a long time. I can understand the message # is not sufficient trigger additional files if only the latest journal file is being written to. However, I see all the 11 files have updated timestamps making me think they are being rotated.
My paging directory is empty.
I am trying to understand why the journal is not growing despite the message volume.
...ANSWER
Answered 2022-Feb-03 at 14:42From what I can tell, message consumption has reached a break-even point with message production so that messages are not accumulating on the broker therefore the journal is not actually growing in size. The journal files are simply being re-used as messages are being added & acknowledged.
QUESTION
I have a use case where I need to convert a message from one type to another (i.e. TextMessage -> ObjectMessage).
I found that when diverting between queues there is an option to transform the message. I have implemented the Transformer interface as instructed in the documentation.
ANSWER
Answered 2022-Feb-02 at 17:23It should technically be possible to convert a javax.jms.TextMessage to a javax.jms.ObjectMessage, but it may be cumbersome. Here are some important things to note:
javax.jms.TextMessage,javax.jms.ObjectMessage, andorg.apache.activemq.artemis.api.core.Messageare all just interfaces. Thejavaxversion is what you use on the client andMessageis what is used on the broker. The data for each type of message is stored differently in the underlying message implementation.- The class for the Java object that you wish to put into the
ObjectMessagewill need to be on the broker's classpath. This isn't required under normal circumstances as the broker itself will never serialize or deserialize the object. - You should really try to avoid
ObjectMessagewhenever possible.ObjectMessageobjects depend on Java serialization to marshal and unmarshal their object payload. This process is generally considered unsafe (and slow!), because a malicious payload can exploit the host system. Lots of CVEs have been created for this. For this reason, most JMS providers force users to explicitly whitelist packages that can be exchanged usingObjectMessagemessages. For example, here's the related documentation for ActiveMQ Artemis. There are a number of other issues with using JMSObjectMessagenot related to security that you should read about.
Granted you understand all that you should be able to convert the message using code something like this:
QUESTION
I'm trying to store the last value of a cell while I parse my dataframe, I can't know what this value will be so I need a dynamic method to do so.
The desired value is stored in the position [row, 2] of my dataframe, but at each new row it changes. I'd like a way to write the position [index, 2] while using my parsing method.
So far my code look like that :

Answered 2022-Jan-18 at 13:47Split your rows in two dataframes: df3 for Code=50 and df4 for Code=10 then merge them:
QUESTION
How to parse data on all rows, and use this row to populate other dataframes with data from multiple rows ?
I am trying to parse a csv file containing several data entry for training purpose as I am quite new to this technology.
My data consist in 10 columns, and hunderds of rows. The first column is filled with a code that is either 10, 50, or 90. Example :
Dataframe 1 :
0 1 10 Power-220 90 End 10 Power-290 90 End 10 Power-445 90 End 10 Power-390 50 Clotho 50 Kronus 90 End 10 Power-550 50 Ares 50 Athena 50 Artemis 50 Demeter 90 EndAnd the list goes on..
On one hand I want to be able to read the first cell, and to populate another dataframe directly if this is a code 10.
On the other hand, I'd like to populate another dataframe with all the codes 50s, but I want to be able to get the data from the previous code 10, as it hold the type of Power that is used, and populate a new column on this dataframe.
The new data frames are supposed to look like this:
Dataframe 2 :
0 1 10 Power-220 10 Power-290 10 Power-445 10 Power-390 10 Power-550Dataframe 3 :
0 1 2 50 Clotho Power-390 50 Kronus Power-390 50 Ares Power-550 50 Athena Power-550 50 Artemis Power-550 50 Demeter Power-550So far, I was using iterrows, and I've read everywhere that it was a bad idea.. but i'm struggling implementing another method..
In my code I just create two other dataframes, but I don't know yet a way to retrieve data from the previous cell. I would usually use a classic method, but I think it's rather archaic.
