an java.sql.SQLException: No suitable driver found for jdbc:h2:tcp://localhost/~/ZadatakDB is thrown when I try to connect to h2 database using a java web application.
I can use H2 console without any issue, and pinging is successfull.
I've also added h2-1.3.176 jar file to Libraries AND to WEB-INF/lib.
Here is my Java method I am using to connect:
private static Connection connectToDatabase() throws SQLException,
IOException {
String url = "jdbc:h2:tcp://localhost/~/ZadatakDB";
String username = "student";
String pw = "student";
Connection connection = DriverManager.getConnection(url,
username, pw);
return connection;
}
What could I be missing?
I will also add StackTrace:
java.sql.SQLException: No suitable driver found for jdbc:h2:tcp://localhost/~/ZadatakDB

The JDBC driver for the H2 database is not in the classpath, or the driver is is unloaded. Use this to load the driver class:

I have use guacamole for three years, begin at 0.9.13.
extensions contain "auth-jdbc-mysql" and "auth-cas"
I had an upgrade to 1.1.0 and all work right，but when I update to 1.2.0, It can't work， if I use MySQL to auth， it also works well, but use cas1.2, I get a whiteboard at login, so I check the logs, The error is as follows(from logs/localhost.2020-11-24.log), I don't know Java, It may be very easy, help me thanks. if I replace use cas1.1 replace cas1.2 and the others remain unchanged
it also works well

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();});

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 have a web app running on Tomcat 8.0. Using Spring for DI, and Jersey for Rest APIs. While I was working on Eclipse, it was running all fine. Then I deployed it on a Ubuntu machine using the URL:
http://localhost:8080/manager/text/deploy?path=/app&war=file:/home/user/Downloads/app-name-0.0.1-SNAPSHOT.war
Now when I hit the APIs, along with the root url, http://localhost:8080/app, it is throwing the following error:

Can anyone please suggest what is happening here?
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

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