I have a problem with spark.
I am trying to load a view "base.hbs" but whenever i try to load it spark throws an FileNotFoundException
I tried changing the constructor to new HandlebarsTemplateEngine("tried/different/paths/here"); but no luck. I even tried putting resources folder in C:/ Drive and loading it externally but still no luck...
I am not using the regular embedded Jetty Server, But I am using a tomcat server... I can assure you that other get methods work(Where i return a string)
Much help appreciated thank you.
Code:
#Override
public void init() {
Map map = new HashMap();
map.put("name", "Sam Cooke");
get("/hello", (rq, rs) -> {
System.out.println(rq.contextPath());
return new ModelAndView(map, "base.hbs");}, new HandlebarsTemplateEngine("resources/templates/"));
exception(Exception.class, (ex, rq, rs)->{ex.printStackTrace();});
}

When the common redirect field was implemented in 1.2.0, several components were left in the CAS module that are causing errors trying to download the app.js file when the module is enabled.

So, like i said on title. I have permissions over target file, but when running my app this exception is displayed

I tried to run a simple app, only to write on file and i had no problems. But when running app on server at tomcat8.0 i get that exception. I searched on web, but i only found answers relatively to file permissions (something that i already own it) or something related with security, that in this case i don't think that is the problem because the exception raised is about FileNotFound.
Thanks in advance! It's my first question, sorry for something you don't like (formatting, language, etc) ;)
Hi i'm deploying an app that i wrote on a machine (all deployment with tomcat).
when running the application (in browser) i get the error

but the application works fine on my machine .
i tried the solution suggested here :
Error Obtaining Lock (org.neo4j.kernal.StoreLockException)
it didn't work , i am accessing the DB using :
db = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(new File("path to the database")).loadPropertiesFromFile("path to properties file")
.newGraphDatabase();
registerShutdownHook(db);
what could be the problem ?
Only one process at a time can access the store directory on disk.
As you start an embedded database, make sure that all servers and other processes accessing that same database are stopped cleanly.
I'am working on a JSP site with a servlet and a Tomcatserver.
At the moment I can't figure out the problem for this error:
javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/jdom2/input/SAXBuilder
I already googled for this problem and tried every possibility.
The jdome2 is included
and there is also no fault about the SAXBuild function in the code
Here is the stacktrace I get when I run the project
SCHWERWIEGEND: Servlet.service() for servlet [jsp] in context with path [/Quiz] threw exception [javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/jdom2/input/SAXBuilder] with root cause

I aleady tried to use jdom1.x.x instead of jdom2 but it didn't work
Hope someone could help me.
Simply move this jdom jar to WebContent/WEB-INF/lib/.
I am assuming that you are not using build tool like maven or gradle.
I have made a simple java Servlet that needs to communicate with a Neo4J server using REST API.
I'm using the following library: neo4j-rest-graphdb-2.0.1.jar.
The only line I have written so far is
RestAPI graphDb = new RestAPIFacade("http://localhost:7474/db/data");
Unfortunately every time I start the servlet I get this error:
org.apache.catalina.core.StandardWrapperValve invoke
GRAVE: Servlet.service() for servlet [servlets.ServletFrontend] in context with path [/ServletTest] threw exception [Servlet execution threw an exception] with root cause

I'm using Eclipse and I've already imported that library (and org.neo4j.rest.graphdb.RestAPI is in there).
What am I missing?
