Currently, I have an Eclipse Scout application (UI + server) deployed on a remote Tomcat server.
For specific development needs, I need to run the client part of my application locally on a computer.
I need this application to continue to access the server part on the remote Tomcat server.
I tried to implement an embedded Tomcat for the ui.html.war project:
public class EmbeddedTomcat {
public static void main(String[] args) throws Exception {
Tomcat tomcat = new Tomcat();
tomcat.setPort(8082);
String webappDirLocation = "src/main/webapp/";
StandardContext ctx = (StandardContext) tomcat.addWebapp("", new File(webappDirLocation).getAbsolutePath());
// Other configurations
tomcat.start();
tomcat.getServer().await();
}
}
I no longer have any errors in the console, but I can't access my application via localhost:8082
I tried to explore the JettyServer option, but I lack the necessary knowledge.
What is the easiest way to achieve my goal?
EDIT : of course I know I can install a local tomcat on my pc, deploy the client etc. But in the end it is directed to my final users, so I want to create a one-click button to launch the client, so I need something embedded.
Thank you

Hello, thank you for your suggestion. Apologies for my delayed response.
I've been experimenting with the Jetty method and here's what I've done so far:
I copied the JettyServer class from org.eclipse.scout.dev.jetty into my project at myproject.ui.html.app.dev.
Running it manually from Eclipse seems successful it launches my client on localhost:8080 and successfully connects to the remote server's war file.
To build a jar, I've updated the pom.xml in my ui.html.app.dev project as follows:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<mainClass>
snippet.JettyServer
</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
This modification successfully builds the jar. However, when I attempt to run it, I encounter an error: the config.properties file cannot be read, even though it's correctly placed in src/main/resources. I've also tried moving the config.properties file to the same location as the .jar, but this hasn't resolved the issue.
(I have also extracted the jar and the config.properties seems to be correctly put in it)
I am getting closer but I definitely need your advices here

Hi there,
Have you tried editing the "service tunnel" section of the config.properties file in your xxx. ui.html.app.dev package? Since the value of the "scout.backendUrl" property is "http://localhost:8080", changing it to the address of your remote Tomcat production server, might just work. for you. I've never tried it though. It is just a suggestion for you to try out.
### Service tunnel
scout.backendUrl=http://localhost:8080
scout.auth.privateKey=xYzxYZ
Cheers,
JD

Hello Stephan, thank you very much, I have done some experiments and it is exactly what I was looking for.
I will slowly migrate my apps and wait for March.
What I don't understand is why I cannot change the front port, even if I play with the value of scout.app.port=8443, it goes at https://mydomain:8082. but not 8443... I am using a signed certificate and had no trouble with tomcat (it was correctly running at HTTPS/8443). I don't understand from where the 8082 comes from.
edit : ok I just noticed It comes from the starting script ... lol. It overrides the config.properties!
set JVM_ARGS=-Xms64m -Xmx512m -XX:-OmitStackTraceInFastThrow -Dscout.app.port=8082
Amazing work on the framework.

Thank you for the update. I have successfully completed the migration of an application, overcoming some initial challenges with the transition from javax to jakarta namespaces using hibernate, as well as resolving issues related to dependencies convergence. The command mvn clean verify executes without any issues, and everything appears to be functioning correctly at this stage. that is very great!
However, when I attempt to perform an 'update maven' operation on my projects, I encounter an infinite loop. Despite attempting to reimport my project into a new workspace, the problem reoccurs after a few builds. While this issue is not critical, I know it is a beta but thought it was important to bring it to your attention.
Additionally, I am experiencing some confusion regarding the Maven configuration. I encountered issues with duplicate classes and found it necessary to explicitly include the following duplicate-finder-maven-plugin configuration in each project's pom.xml file:
<plugin>
<groupId>org.basepom.maven</groupId>
<artifactId>duplicate-finder-maven-plugin</artifactId>
<executions>
<execution>
<phase>none</phase>
</execution>
</executions>
</plugin>
In previous versions, it was sufficient to specify this plugin only in the parent pom.xml. This change in requirement has added to the complexity of managing the project configuration.
And finally, when I use Ctrl+Space to create a column or a field, it doesn't seem to work. It is reproductible in the helloworld project.
I am currently using Eclipse 2023-12 with the 23.1 beta version.

Hello,
You're right, it's my fault. I was using the wrong Eclipse (2023-12 instead of the future 2024-03), It solves the autocomplete issue (well present in 2023-12 though, what ever the version of scout I pick). Also, yes, I migrated from javax to jakarta.
Regarding the duplicate dependencies, it's after adding Hibernate, which seems to create a lot of duplicates. I haven't had the time to thoroughly analyze all of this yet, I reused the dependencies from my 22.x project where I know everything works to save time. For now I simply duplicated my disabling of the duplicate-finder in each pom.
