cannot start cas-overlay-template on windows - missing \etc\cas\thekeystore

I am trying to run https://github.com/apereo/cas-overlay-template on Windows 11 and JDK 11 (Eclipse Adoptium 11.0.16.1), using the 6.5 branch. I have ran the "createKeystore" and "copyCasConfiguration" gradle tasks using gradlew.bat, and it created the files below:
c:/etc/cas/cas.crt
c:/etc/cas/thekeystore
c:/etc/cas/config/cas.properties
c:/etc/cas/config/log4j2.xml
when I tried to run "gradlew.bat run", it hit the following error:

I believe this is due to Gradle thinking its running inside a Unix environment instead of a Windows one. Any changes I make to the c:/etc/cas/config/cas.properties file is ignored, which makes me believe that its looking elsewhere for the cas folder (not c:/etc/cas). Anyone got any ideas?

You can change the keystore location in spring config. You can pass the property either in cas.properties or with command line flags or ENV. Two examples:
Example: absolute windwos path
server.ssl.key-store=D:/dev/cas/etc/theKeystore.jks
Example: relative path
server.ssl.key-store=file:etc/cas/thekeystore
By the way, you can also change the location of the cas.properties file with the cas.standalone.configurationDirectory parameter. This is how I usually work in a local environment on Windows:
java -jar build/libs/cas.war --cas.standalone.configurationDirectory=etc/cas/config --debug

Anyone got any ideas?
Please read:
https://apereo.github.io/cas/6.5.x/installation/Troubleshooting-Guide.html#review-logs
CAS server logs are the best resource for determining the root cause of the problem, provided you have configured the appropriate log levels. Specifically you want to make sure DEBUG levels are turned on the org.apereo package in the log configuration
You could consider moving the configuration inside the CAS build itself in an application.yml file, instead of keeping it outside.
https://apereo.github.io/cas/6.5.x/configuration/Configuration-Server-Management-Standalone.html

Try switching from tomcat to jetty as an embedded servlet server. It seems to have better windows support, and properly looks for c:\etc\cas\thekeystore.
To do that just replace -tomcat with -jetty as appServer in the gradle.properties file.
There might be a way to teach tomcat to look at the right place, but I didn't found it. The server.ssl.key-store setting didn't had any effect.

Tomcat server won't start if WEB-INF/classes directory exists

I am currently working on a Dynamic Web Project for school and I am running into a weird problem... I am trying to run a servlet from a .jsp file. I did a lot of research and apparently (please correct me if I'm wrong!) you need to place the compiled servlet or java class files into WEB-INF/classes directory if you want to use them within the .jsp file.
Before setting the build path to be this directory or even creating the directory, I was able to run my web app. The second I made the change to the build path, my server refused to start and I am now getting this error:

Does anyone have any ideas on how to fix this? Any help would be greatly appreciated!

You are getting both mapped to the url-pattern exception because when Tomcat is trying to load the servlet classes, it has found 2 mappings for the same servlet i.e., one from web.xml and another from #webservlet.
#webservlet is an alternative way (in JavaEE6 containers) to define the servlet url mapping (inline to the servlet source code). So you should NOT add those servlets and mapping into the web.xml (i.e., just remove the web.xml from WEB-INF folder).

Error occurred during deployment: Exception while loading the app :

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: java.lang.VerifyError: class org.apache.axiom.om.impl.dom.factory.OMDOMMetaFactory overrides final method createSOAPMessage.(Lorg/apache/axiom/om/OMXMLParserWrapper;)Lorg/apache/axiom/soap/SOAPMessage;. Please see server.log for more details.
How can I overcome this error?I use Java MVC and Tomcat server.

That error may occur if you mix JARs from different versions of Apache Axiom.

Where is the problem??
Thank you very much!
Matteo

Since you're running embedded Neo4j this looks like you're missing lucene-core-3.6.2.jar on your classpath.
Best practice is to use a build system supporting transitive dependencies like gradle or maven. For those the most easy this is have a dependency on neo4j-community artifact, e.g. http://mvnrepository.com/artifact/org.neo4j/neo4j/2.2.5. This will pull in all other required jars.

Deploying a WAR to virgo-tomcat server

I have been stuck for the last couple of days deploying a standard WAR to Virgo-tomcat server (version 3.0.2). The standard WAR file exported from eclipse works perfectly fine on tomcat, but not when deploying to Virgo-tomcat.
I have read the users-guide and the programmers guide, and as far as I'm aware - it should be a case of deploying the WAR to the VIRGO_HOME/pickup directory (or alternatively using the application manager). I have tried both methods, yet nothing works.
Here are the results from the logs.

Ok, so after testing a couple of test applications, I managed to get some sample WARs to run on Virgo without any modification.
To fix the problem at hand, I added the following line to the MANIFEST.MF file of my web app.
