derby | A pure Ruby Fedora Commons implementation

The Problem:

I am using Docker Compose to create two containers: One with a Postgres database on it and the other with Flyway on it. The goal is to use Flyway to migrate scripts to the Postgres database instance. When I run docker-compose up I get the following error:

Unable to obtain connection from database (jdbc:postgresql://db:5432/) for user 'luke_skywalker': The connection attempt failed.

My code is below and thank you for your help!

Here is my docker-compose.yml:

I created table using Derby database

im trying to create a simple code where it get name from the user and insert it into the table , it first goes to a servlet to check if user left textbox empty or not then to goes to the jsp if correct and then i created a class named user to get input from user and insert it into the table my problem is its doesnt insert it into the table after thee run is finished

here is index.html:

I'm trying to set up a Java DB Database for a programming class. I'm following the steps in the Deitel and Deitel textbook:

I have JDK11.8.0_112 installed. I'm running Windows 10.

My install is at C:\Program Files\Java\jdk1.8.0_112 I have the JAVA_HOME var set as C:\Program Files\Java\jdk1.8.0_112

The textbook says to go the install location db\bin and edit the setEmbeddedCP.bat file from @rem set DERBY_INSTALL= to @SET DERBY_INSTALL=%JAVA_HOME%\db

Then open a command prompt and go to the directory of that file and run it, which I've done, this is the result:

The book has some source code to create the tables. I copied and pasted into my own project, C:\Users\hulbe\OneDrive\Documents\NetBeansProjects\DisplayAuthors\build\classes\displayauthors.

The book then states to use the command line and change directories to the folder with chapters examples, which are now in my own project.

Next, type "%JAVA_HOME%\db\bin\ij" into the command line.

Then, connect 'jdbc:derby:newbooks;create=true;user=xxx;password=xxx'; I've got the DB and the tables to create (I think). But when I run the code I get "java.sql.SQLException: No suitable driver found for jdbc:derby:newbooks"

I'm really at my wits end here. I've spent two days now trying to set up clean installs and walking through exactly like how the books is set up.

Here's the code: `try ( Connection connection = DriverManager.getConnection( DATABASE_URL, "deitel", "deitel");

I'm trying to update my database where in the Book copies will be updated to 5 depending on the Book code.

The Book copies I initialize in the database was 10. For now, I have a fixed value of 5 to change it. My plan is to decrement the copies by 1 if users borrowed it. But for now, I'm trying to learn how to update the book first if it will work.

Here's my code where the Book copies in my database still hasn't updated to 5.

I see examples that convert a Flink Table object to a DataStream and run StreamExecutionEnvironment.execute.

how would I code + run a continuous query that writes to a Streaming Sink with the table API without converting to a DataStream.

It seems this must be possible, because otherwise what is the purpose of specifying streaming sink Table Connectors?

The Table API docs list continuous queries and dynamic tables, yet most of the actual Java APIs and code examples seem to only use the table API for batch.

EDIT: To show David Anderson what I'm trying, here are the three Flink SQL CREATE TABLE statements on top of analogous Derby SQL tables.

I see the JDBC table connector sink supports streaming, but am I not configuring this correctly? I don't see anything that I'm overlooking. https://ci.apache.org/projects/flink/flink-docs-release-1.12/dev/table/connectors/jdbc.html

FYI, when I get my toy example working, I am planning on using Kafka in production for input/output stream-like data and JDBC/SQL for the lookup table.

I want to allow the user to drag and drop a link onto the list, which will enter the URL into the database, allow the user to view all links, articles, or something similar on the page in the upper right corner(even simple details such as title and when link was added would be fine), and then view the webview. I cant get it to correctly display the URL details in the upper right corner, or display the webview correctly in the bottom right. I am very familiar with javafx and derby, just not so much with the web aspect. Any help would be greatly appreciated. As of now, the URL can be dragged and dropped onto the list, and the title and some details are displayed incorrectly in the upper right. The webview doesn't work either most of the time. The hyperlink doesn't get displayed correctly in the list either, but that is just some formatting that needs fixed. The end goal is just to allow the user to monitor new posts, articles, or news, on the URLs they enter.

I have encountered an issue with our JForg Artifactory v7.12.6

We needed to install our self signed certificate on our servers, added it to the CentOS trust and the java certstore so far so good.

Then restarted the Artifactory. After some investigation of the logs, I saw that the access server doesn't properly start. It terminates with NPE because it can't load a configuration. So the Artifactory service itself fails to start as it can't reach the access server.

I'm making a javafx Library Management System project using intellij idea that uses derby as an embedded db, and it works just fine, but when i convert my project into a jar file using the build artefact option in intellij idea then convert that jar into an .exe file using launch4j and try to run it, it will throw a

JavaFX runtime components are missing, and are required to run this application

i tried adding the jvm options through the jvm options section in launch4j but then i would get another error saying that i can't access the sub packages that contain the other classes that i want to use :-

the thing is that i want this program to run when i run the .exe file so is there a way to add these jvm options inside my code, or is there a better way to run javafx-db programs with a different extension ? and how should i include in the jvm options that i'm using sub packages?
