Opened this issue · 5 comments
I am working on lab "In-container Java Development: Eclipse", and failed to start app "/UserSignup"
Host OS: Windows 7 Enterprise
VM: Oracle VM VirtualBox 5.2.20
Ubuntu 190.04.1 is installed in the Oracle VM
Docker 18.06.1-ce is installed in the Ubuntu
The following are the container log, and shows SEVERE error about JDBC driver.
How can I fix it ? Thanks

have you solve this problem? I meet it today
OK,
First replace in pom.xml:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.3.1.Final</version>
</dependency>and then create server.xml in developer-tools/java-debugging/registration-webserver/tomcat/server.xml
write following content to it:
<?xml version='1.0' encoding='utf-8'?>

finally,add
RUN rm $CATALINA_HOME/conf/server.xml
ADD tomcat/server.xml $CATALINA_HOME/conf/
to developer-tools/java-debugging/registration-webserver/Dockerfile
then just rebuild with docker:
docker-compose up --buildi've fixed this by upgrade spring-webmvc version in pom.xml file

</dependency>Thanks @kevin-isky . Did you open a pull request with that? Seems like a reasonable thing to do anyway.
