My Spring-Boot app works fine when running it via the Eclipse IDE (with S.T.S. 3.8.4 installed), with the embedded tomcat server.
I packaged it as a WAR and deployed it to a local Tomcat server.
When accessing the app, a blank page is returned. I discovered the exception in the Tomcat logs (on Windows, C:\<path-to-tomcat>\logs) An exception is thrown when trying to resolve the Thymeleaf templates:
2017-04-04 12:33:36.602 ERROR 5724 --- [io-12080-exec-7] org.thymeleaf.TemplateEngine : [THYMELEAF][http-nio-12080-exec-7] Exception processing template "home": Error resolving template "common/layout", template might not exist or might not be accessible by any of the configured Template Resolvers (template: "home" - line 5, col 7)
org.thymeleaf.exceptions.TemplateInputException: Error resolving template "common/layout", template might not exist or might not be accessible by any of the configured Template Resolvers (template: "home" - line 5, col 7)
at org.thymeleaf.engine.TemplateManager.resolveTemplate(TemplateManager.java:865) ~[thymeleaf-3.0.2.RELEASE.jar:3.0.2.RELEASE]
The problem was the casing of the folder names.
I had my layout fragment in templates/Common/layout.html (notice the capital C in Common) and in my views was referencing common/layout, which worked within the IDE, but did not work when deploying a WAR on a Tomcat server. Maybe because the IDE ignores casing, and Tomcat is case sensitive?
It worked after changing the reference in my view to the correct casing of the folder, Common/layout

Configuration
My Spring Boot/Liquibase specifications & configuration is as per this question.
Issue
Everything goes well in my local environment with embedded Tomcat. When i migrate the war file to IBM WebSphere 8.5.5.15, i see this warning:
[7/29/20 11:04:17:302] 000002ff database I liquibase.database Could not set remarks reporting on OracleDatabase: com.zaxxer.hikari.pool.HikariProxyConnection.setRemarksReporting(boolean)

I have checked and the jar file is not there at the location that it is looking for it.
Question
It's only a warning, everything else is working as expected, should i be concerned about this warning?
After fresh install of web logic, deployment shows the error:
Message icon - Error Failed to load webapp: MyWebApp because of DeploymentException:

After I changed the name to something - Error is

Your web application requires the JSF 2 shared library which is not deployed in your server. Deploy this library first and then your application.
Folks, I have a spring-boot app running locally with gradle build tool, with custom: server:
servlet-path: /own/api
port: 8989 without any problem. However it doesn't work in WindowServer 2008-R2, I just get in log:
DispatcherServlet with name dispatcherServlet processing GET request for [/own/api]
Looking up handler method for path [/own/api]
Maybe WindowsServer would require something extra configuration, but not sure, i guess to deploy a spring boot application with tomcat embedded wouldn't have any trouble:
java -jar myfile.jar
Under AdvancedREST client tool I just get:
http://SERVER-API:8989/own/api
{
"timestamp": "2016-07-05T21:13:25.884+0000"
"status": 404
"error": "Not Found"
"message": "/own/api"
"path": "/own/api"
}
As aforementioned, locally it works fine but not in windows server 2008R2. I was wondering if there was a manager in tomcat embedded, just to figure out what basePath would be, because I tried with:
http://SERVER-IP:8989/myfile/own/api //but didn't work either.
Any help I'd really appreciate.
Folks, I found the solution which is adding a slash character to the end of the URL.
http://server:port/own/api/ instead of http://server:port/own/api
I've faced with this issue in the past in other scenarios with Tomcat.
I have deployed ear files in oracle weblogic server and i also configured datasource for that project. When i try to test it it is giving me this error.
"Message icon - Error weblogic.application.ModuleException: :org.springframework.beans.factory.BeanDefinitionStoreException:Invalid bean definition with name 'userContext' defined in class path resource [voyager-seats-usercontext.xml]: Could not resolve placeholder 'IDM.USERNAME'
Message icon - Warning Errors were encountered while performing this operation."
I restarted and reconfigured this app still it is giving error.
I have been developing a video sharing web application (like youtube) using Netbeans with Tomcat on Windows platform. There I want to generate thumbnail images of video files as soon as the videos get uploaded. So searching the net I found something called Xuggle. I installed Xuggler in my Tomcat's lib folder. I have set the necessary environment variables. When I run just a java application I get the results, but when I do the same with a Java web application I get the following errors:
HTTP Status 500 -

#pd40 >>> I reinstalled Xuggler ( this time in C:\Program Files , I restarted my PC after installation . I set the following in my environment variables :
XUGGLE_HOME = C:\Program Files (x86)\Xuggle
CLASSPATH = .;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\commons-cli.jar;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\logback-classic.jar;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\logback-core.jar;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\slf4j-api.jar;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\xuggle-xuggler.jar;C:\Apache Tomcat 6.0.26\Apache Tomcat 6.0.26\lib\xuggle-xuggler-test.jar;

I have copied the jars of Xuggle/java/jars (6 jar files) in The Tomcat's\lib folder and set the CLASSPATH of them.
Now I still get the problem when i do this in a web application , but standalone java application generates the images nicely. What is going wrong ??? When i upload a video it gets uploaded but the thumbnail images are not generated , I get the following error...
HTTP Status 500 -

Make sure you put Xuggler lib in your windows PATH or LD_LIBRARY_PATH.
Similar to Tomcat native. I assume you have tried this.
