Are you sure that the new {{war}} package was correctly deployed without any
exception in the logs? Because you are using a lot of conflicting versions of
jars which can block deployment.
{code:xml}
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.24</version>

this is duplicated, it shouldn't be an issue though
{code:xml}
<dependency>
<groupId>javax.enterprise</groupId>
<artifactId>cdi-api</artifactId>

do you need these?

You don't have to define these, they are transitive dependencies already from
other packages.

you have to exclude)

> WebLogic 12.1.3
> JDK 1.7
> Reporter: Rin Saunders
> Priority: Minor

> Am getting a null pointer error in the FreemarkerManager class. It occurs in
> the setContainer method. The code below seems to assume that getInstanceNames
> returns an empty set if there are no matches. In fact, it returns a null,
> which is legit according to the XWork doc. This occurs in Freemarker 2.3.23
> under WebLogic 12.1.3.
> {code:java}
> Map<String, TagLibrary> oldMap = new HashMap<String, TagLibrary>();
> Set<String> oldPrefixes = container.getInstanceNames(TagLibrary.class);
> for (String prefix : oldPrefixes) {
> oldMap.put(prefix, container.getInstance(TagLibrary.class, prefix));
> {code}
> Not sure if this affects the presentation of Struts2 views. Is there a
> workaround or fix?
