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

Can you start the client application locally from your IDE? You may be able to take a look how it is started there (and maybe copy/paste from there), starting from the IDE usually a Jetty server with a main method should be used.

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 JD, thank you for your suggestions but I am further in my experiment I already figured that I can change this URL.

My issue is to load the config.properties file. I have tried using the -Dscout.env=file:linktoconfig.properties but it still try to load the original config.properties

I have just noticed there is a new commit in the framework : "Scout Application (Jetty): improve for using in non-development mode" : https://github.com/eclipse-scout/scout.docs/commit/1d14684721be6e654246055c8f9d27330045bbee

Seems like somebody accomplished something I am trying to do. I don't know how to make work, I am in 23.9

With Scout 24.1 (only beta now, will be released in March 2024), the Scout application will not provide a .war anymore but instead use an embedded Jetty directly. One way of running a 24.1 Scout application in a productive environment is described in this tutorial.

Running a 23.2 Scout application in a similar way locally should be possible, you might get some more inspiration by having a look at the ui.html.app.zip module as generate by the updated Scout Archetype for 24.1. Be aware that there were several changes between 23.2 and 24.1 regarding the former dev Jetty server (migration guide).

Either use your IDE and the wizard to create a new Scout Classic project with version 24.1.0-beta.1 or use the command:

mvn archetype:generate -B -DarchetypeGroupId=org.eclipse.scout.archetypes -DarchetypeArtifactId=scout-helloworld-app -DarchetypeVersion=24.1.0-beta.1 -DgroupId=org.example.lorem  -DartifactId=org.example.lorem -Dversion=1.0-SNAPSHOT -Dpackage=org.example.lorem -DdisplayName=Lorem -DjavaVersion=11 -DsimpleArtifactName=lorem

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.

Thanks for your feedback, glad to hear.

And sorry for the confusion regarding the HTTP port, I've improved the tutorial regarding the override in the shell scripts, see this commit.

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.

As far as I understand, it should still be possible to specify the plugin settings once in the parent pom.xml.

However I am curious why it is necessary to disable the duplicate-finder; would it not be possible to exclude specific duplicate dependencies from the dependencies providing the duplicate classes? What classes are duplicated if the plugin is not disabled?

Hi,

you have migrated your applications to 24.1 and with this you have transitioned from javax to jakarta, is that correct?
The Eclipse Scout SDK bundled in Eclipse 2023-12 (SDK-version 13.0.27) does not support the new jakarta-dependencies, but the one bundled in the March release will (SDK-version 13.0.28).
How you can install a new SDK version is explained here. Just use the update site http://download.eclipse.org/releases/2024-03.
I tested with a new 24.1-Helloscout-project and this solved the infinite maven-update and the Ctrl+Space problems for me. For Ctrl+Space I noticed that it only works if you haven't typed anything yet. I don't know if thats how its supposed to work, but I will look into it.

Kind regards,
Fritz

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.
