Deployment of FROST-Server.MQTTP-x.y.z.war not working

[eskotilla]

Hello,

We have tried to deploy a FROST Server using FROST-Server.MQTTP-x.y.z.war pre-built file, but after following the steps described in https://fraunhoferiosb.github.io/FROST-Server/deployment/tomcat.html, we're not able to make it working. We're not really proficient with Tomcat so, sure we're missing some configuration.

We have the following scenario:

• Ubuntu Server 24.04 LTS with PostgreSQL 16 and Tomcat 10 installed all in the same machine
• Created database "sensorthings" within public schema with extensions uuid-ossp, postgis and timescaledb
• Created user "sensorthings" with password "ChangeMe" and all privileges on database "sensorthings"
• Installed WAR file using Tomcat's manager webapp, and checked that http://localhost:8080/FROST-Server is working fine
• Copied "postgresql.jar" and "postgis-jdbc.jar" into both FROST-Server/WEB-INF/lib and /var/lib/tomcat10/lib folders
• Updated FROST-Server/META-INF/context.xml with the following lines

\ \ \ \ \<Resource name="jdbc/sensorThings" auth="Container" type="javax.sql.DataSource" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/sensorthings" username="sensorthings" password="ChangeMe" maxTotal="20" maxIdle="10" maxWaitMillis="-1" defaultAutoCommit="false" />

• Created file FROST-Server/WEB-INF/classes/application.properties with the following lines:

spring.datasource.url=jdbc:postgresql://localhost:5432/sensorthings spring.datasource.username=sensorthings spring.datasource.password=ChangeMe spring.datasource.driver-class-name=org.postgresql.Driver spring.datasource.driver-class-name=org.postgresql.Driver persistence.persistenceManagerImplementationClass=de.fraunhofer.iosb.ilt.sta.persistence.postgresql.PostgreSQLPersistenceManagerString

We can get main FROST-Server web page to work, but when we click on any link, like "DatabaseStatus", we get the typical tomcat's "404 - Not found" error message:

The requested resource [/FROST-Server/DatabaseStatus] is not available

We will appreciate if anyone can guide us to get it working.

Thanks in advance

FROST-Server currently requires Tomcat 9. From 9 to 10 the namespace of all JavaEE classes changed, so it's not really possible to support both. Some users have managed to run FROST on Tomcat 10 by using the conversion tools that are supplied with Tomcat, though if you are not experienced with Tomcat it's probably easier to start with 9.

Also, FROST does not use Spring, so creating an application.properties file is pointless. That's also not in the steps described in the documentation.

Look in the log files of Tomcat to see any errors.

Hi, we finally successfully deployed FROST-Server on Tomcat 9 (and solved other minor issues related to "jar" files) so, we're now able to use APIs to operate with data.

Now we are wondering if there is a version of FROST Server with all SensorThings extensions. That is, we would like to be able to have STAPlus and Tasking Core, either a complete version including endpoints and API, or just with the tables only defined and created.

Thanks

The supplied plugins can be configured using environment variables or Tomcat parameters. See the documentation for that. The STAplus plugin is not maintained by us.
