Eclipse Scout Helloworld - Initialization Failed [message #1739416]

Hello,
I am new to scout. I followed the tutorial, launching the server and ui within eclipse works. However, after deploying the war files on tomcat and logging in (either with scott or admin) leads to an initialization failed error.

I have not worked with tomcat either. Is there a way to see the logs to see what could be causing this?

If that happens, the initial startup request to the server failed. The UI is therefore not initialized and got no texts or other information from the server, therefore it can only display this very basic error message.

To find the real cause of the problem, you have to check the server logs. The exact location of those depend on your logging configuration (the tomcat docs for details). A good point to start your search would be the "logs" directory inside the tomcat installation directory. Under a Linux environment, "/var/log/tomcat" or similar is also not uncommon.

Beat

If you do a simple deployment on one tomcat, you need also to change the proprty scout.server.url, which is not described in the scout getting started documentation. If you run your tomcat on port 8080 and on the same server, you might change the proprty as follows. (your.app.name is what your backend server name is which is ok by default)

scout.server.url=http://localhost:8080/your.app.name

What is the value of your 'scout.server.url' property? This is the URL that the UI application uses to access the backend. Is this URL valid and working?

By default the https protocol and port 8443 are used.
If your server uses a different port you might need to change that to match your Tomcat setup.
The same for the protocol: Either you setup https in your Tomcat or (if you don't need it) change it to http instead. Please note that it is strongly recommended to use https in a productive environment.

Does this help?

thank you for your support.
i found the problem, i didn't add my self-signed certificate to "cacerts" file of JRE that exists in the JDK folder (C:\Program Files\Java\jdk1.8.0_144\jre\lib\security), not the JRE that exists in java folder (C:\Program Files\Java\jre1.8.0_144\lib\security)
