POM.xml Shows errors - Beginner

I created a project using the following command

mvn archetype:generate -B -DarchetypeGroupId=org.appfuse.archetypes -DarchetypeArtifactId=appfuse-light-spring-security-archetype -DarchetypeVersion=2.2.1 -DgroupId=com.app.PROJECT1 -DartifactId=PROJECT1 -DarchetypeRepository=https://oss.sonatype.org/content/repositories/appfuse

and i then i opened it in eclipse after typing mvn eclipse:eclipse.

In the pom.xml i see the following errors, how can i resolve this.

QUESTION 2.

I have included a screenshot of the app below when i run it in localhost, and i don't see the CSS is working here, as the UI is messy. How can i solve this ?

QUESTION 3.

I get the following error when i clean install

[ERROR] Failed to execute goal org.codehaus.mojo:dbunit-maven-plugin:1.0-beta-3:operation (test-compile) on project PROJECT1: Error executing database operation: CLEAN_INSERT: Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-170] -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:dbunit-maven-plugin:1.0-beta-3:operation (test-compile) on project PROJECT1: Error executing database operation: CLEAN_INSERT

I believe the answer to #1 is similar to an answer I just posted on the mailing list.
