I have generated a Recommendation engine in Mahout. I have tested the Engine as a Stand Alone Java program.
Now I want to deploy it as a Web Application and hence I am using Apache Tomcat to deploy this Java Application. But when I execute my program on Tomcat Server, I get the following Error:
I have added all dependencies and tried searching the net also on this but with no success. As I am new to Tomcat, requesting you to kindly help me out in resolving the stated issue.
Any kind of help is highly appreciated.
Thank You

This has been asked before but the only answers I saw were "restart or re-install tomcat" and similar and they're not working.
I'm trying to get a simple Java web app to work. I downloaded the example from a textbook website. The web app compiles with 0 errors but I get the following message:
org.apache.catalina.startup.Catalina start
SEVERE: Cannot start server, server instance is not configured
This is a picture view of the error
Here is images of the run configuration
I hope this helps you guys see what could possibly be going wrong. I tried to install Apache tomcat 9 and 8 and I have both and I switch between them to see if any work but I get the same error each time. I know it has nothing to do with conflicting versions because the error was happening even when I only had Tomcat 9.
I am trying to deploy my web application on my Payara 4.1 server. However I am getting the following error: java.lang.NoSuchMethodError: javax.faces.application.Application.addSearchKeywordResolver(Ljavax/faces/component/search/SearchKeywordResolver;)V
When I google this issue, I find a few people with the same problem, however they were all using outdated versions of Primefaces, but I am using the latest version (6.2) as you can see in the full logs below.
I've deployed my application before but I changed too much at one time so I don't know what triggered this error. However I did not change any of the library's/dependency's as for as I am aware.
If you need more information, let me know.

I eventually deployed my application on a Glassfish 5 server and it worked again, I have no idea why though.
I am trying to make a web app with neo4j. But the problem is, everywhere the tutorials are for neo4j in embedded mode which is not suitable for web app( please correct me if i am wrong). I found this to connect to neo4j server but the maven dependency is not working. There is a downloadable jar file at that link, i added it to my library and tried with example code but the it showing classnotfoundexception. I went to maven repository site to search that neo4j-jdbc but cann't find anything . It seems i am stuck at the very first thing . Can anybody help me with this?
As of today the best way to interact with Neo4j is the transactional Cypher REST endpoint. Depending on your client side language/framework couple of drivers do exists, see http://neo4j.com/developer/language-guides/.
The current JDBC does have dependencies on jar files that are not available via maven central and consequently cannot be sent to maven central either. https://github.com/neo4j-contrib/neo4j-jdbc shows an example how to use it.
I am trying to build up a Java (Java version build 1.8.0_11-b12) Maven Web Application (built up in NetBeans 8.0) that runs on Wildfly-8.1.0.Final using JPA (EclipseLink JPA 2.1) for accessing a MySQL database. The host system is Ubuntu 14.04 64Bit.
I have successfully created the datasource on Wildfly to the database on MySQL. Testing the connection sends back a message saying it was successful. Therefore, I think Wildfly should be working fine.
I then created a very simple Entity Class "Dog.java" for persisting.
The problem comes up when I compile the WAR file and copy it for deployement on the Wildfly server. Wildfly sends back endless yellow warning messages and I am not able to kill Wildfly or Java. The only way out is to restart the entire operating system.
Does anyone know this problem? Or das anyone see any problem in my configuration?
Does maybe anyone know a Howto somewhere on the net that explains Step-by-Step how to create a Web Application for Wildfly accessing a database with JPA? I already tried to find one, but was not successful.
Every help highly appreciated! Thanks in advance!
Have a look at the WildFly Quickstarts.
I am trying to figure out how to deploy my WebService project to my running Jboss server. This seems to be a lot harder than it sounds. I can not find any tutorials or guides on how to do this.
I have tried to deploy the whole Web Service Application project as a .rar file via the administrator console but it gives an "unknown error". I am able to run the WebService on the developer webserver.
Is there any best practice or other lean way to deploy my webservice directly in Visual Studio?
I've also tried to publish the project through Visual Studio but the wizard says that localhost:8080 which is where my Jboss application server is running on, but it says that it doesnt exists.
Any suggestions on how to do this?
JBoss can only run applications that are compiled to JVM bytecode. A .NET application is using the CLR runtime, not the JVM.
