[jira] [Created] (GROOVY-8294) Return 404 for non-existing paths in
`TemplateServlet` when running from .war
Thomas Reifenberger created GROOVY-8294:
-------------------------------------------
Summary: Return 404 for non-existing paths in `TemplateServlet` when running from .war
Key: GROOVY-8294
URL: https://issues.apache.org/jira/browse/GROOVY-8294
Project: Groovy
Issue Type: Bug
Environment: Payara Micro
Reporter: Thomas Reifenberger
Attachments: broken-template-servlet.tar.gz
When TemplateServlet was used in application servers that don't unpack a war (i.e. when the real path of resources could not be retrieved), an internal server error is returned upon trying to retrieve a non-existing template file.
The expected behavior would be to get a 404, just as it is already the case when running from a extracted war.
I had this behavior when running on a [payara micro|https://www.payara.fish/payara_micro] application server using the following {{web.xml}} snippet:
{code}
<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
<servlet>
<servlet-name>GroovyTemplate</servlet-name>
<servlet-class>groovy.servlet.TemplateServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>GroovyTemplate</servlet-name>
<url-pattern>*.gsp</url-pattern>
</servlet-mapping>
</web-app>
{code}
and requesting an url ending in {{*.gsp}}, but without a template with that name present.
Please see the attached minimal example.
Run it with:
{code}
./gradlew runDockerContainer
{code}
and test the URLs
http://localhost:8080/test.gsp (works)
http://localhost:8080/unknown.gsp (500, but I would actually expect a 404)
The corresponding stacktrace is
{code}
java.lang.NullPointerException
