sample

Thomas538 · October 7, 2019, 5:59pm

I try to use the sample from

https://vaadin.com/tutorials/migrating-java-swing-to-web-with-vaadin

the link to GitHub is not working. How can I use the code parts from the tutorial?

ollit.1 · October 8, 2019, 6:55am

Is https://github.com/vaadin-learning-center/vaadin-platform-for-swing-developers/ what you’re looking for?

yes

I’ve tried with intellij and with netbeans. There is an error message when opening http://localhost:8080/server-1.0-SNAPSHOT/

netbeans:

Seems to work ok for me. Did you follow the steps in README.md? The error message seems to point at some JEE configuration issue.

Thomas538 · October 9, 2019, 10:23am

yes, in the README.md the steps are

```
build from top level with mvn install
```

import the project to your IDE and make one top level build

start the server module with mvn tomee:run from the module root or by deploying the server module manually to TomEE server configured in you IDE.

Web UI is then available at http://localhost:8080/server-1.0-SNAPSHOT/

The Swing UI can be launched directly from IDE by executing main method from SwingApplication class in desktop module. Note: the server needs to be running.

could you note which IDE you are using and where you clicked for this 5 steps?

ollit.1 · October 9, 2019, 10:28am

I’m using IntelliJ Idea. For the first steps, I used the Maven menu from the right hand side and for the last one, I used right click → “Run ‘SwingApplication.main’” on the left hand Project tree’s SwingApplication class.

Thomas538 · October 9, 2019, 11:31am

with IntelliJ in the first step I get a warning:

[INFO]

Thomas538 · October 9, 2019, 11:32am

and what is the difference between the first two steps?

ollit.1 · October 9, 2019, 11:39am

You should be able to run the Vaadin app without any IDE altogether; just run the Maven commands from command line (eg. mvn install in the root directory and mvn tomee:run in the server directory). What happens when you try that?

Thomas538 · October 9, 2019, 11:49am

I’ve no mvn command in the path. With a separately installed mvn or the mvn-path from the IDE?

ollit.1 · October 9, 2019, 11:54am

As long as the Maven version is 3.6.0 or greater, it doesn’t matter where it’s coming from.

Thomas538 · October 9, 2019, 12:20pm

I installed a fresh maven 3.6.2. and used the command line
When I do the mvn install at the top level there is the same warning as above.
When I do the mvn tomee:run at the server modul level there is again the error:
09-Oct-2019 14:15:42.916 INFORMATION [http-nio-8080-exec-4]

ollit.1 · October 9, 2019, 12:54pm

Which Java version are you using?

Thomas538 · October 9, 2019, 1:19pm

I’m on OpenSuse 15.0 with the provided OpenJDK 10.

ollit.1 · October 9, 2019, 1:23pm

Can you try with Oracle JDK 8 instead?
