I tried to connect my MS Access Database in Mulesoft using Ucanaccess driver but it raises error Could not load class net.ucanaccess.jdbc.UcanaccessDriver. I have imported all the required JAR's and added the required dependencies in pom.xml also but still it gives same error. I have attached all nescessary details of the problem. Java version - 8, Ucanaccess driver version - 5.0.1 Any suggestion or guidance to proceed further would be helpful for me.

Looks like you need to add the JDBC driver libraries as shared libraries in the pom.xml.
See the documentation at https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#configure-shared-libraries on how to configure.
Example (you might need to add other libraries):
<sharedLibraries>
<sharedLibrary>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
</sharedLibrary>
</sharedLibraries>

I am working on backbase identity version 2022-08-LTS. Trying to use custom authenticator using link but when i execute the command java -cp ../custom-authenticator/target/custom-authenticator-2022.08-LTS-jar-with-dependencies.jar:backbase-identity-1.10.6.1-cr.0.jar io.quarkus.runner.GeneratedMain from backbase-identity module then got error Error: Could not find or load main class io.quarkus.runner.GeneratedMain Caused by: java.lang.ClassNotFoundException: io.quarkus.runner.GeneratedMain can any one help me on it
I am testing the Quarkus capabilities for Travel Applications and I found a weird behaviour when I try to establish an URLConnection running in a GraalVM application
based on Quarkus. If I run a Native application:
./target/getting-started-1.0.0-SNAPSHOT-runner
and I Call the REST endpoint:
curl 'http://localhost:8080/api/v1/covid-restrictions'
then I receive the following error:
2022-06-01 17:38:43,844 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-0) HTTP Request to /api/v1/covid-restrictions failed, error id: f6130b71-c9fb-4a67-a996-c58fba695117-1: com.amadeus.exceptions.NetworkException: [---]
But when I run the same application as a Jar, everything is fine.
java -jar target/quarkus-app/quarkus-run.jar
One example to see the error here:
https://github.com/jabrena/quarkus-amadeus-sdk-demo
Do I need to configure the Quarkus app in some way for GraalVM?
I share the whole StackTrace if it could help:

As most APIs nowadays are, the Amadeus library is HTTPS only.
For Quarkus in native mode, you need to explicitly enable SSL in src/main/resources/application.properties (except for certain extensions, see the link below).
quarkus.ssl.native=true
See https://quarkus.io/guides/native-and-ssl
After adding this property you will get a different runtime error:
2022-06-02 00:45:25,381 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-0) HTTP Request to /api/v1/covid-restrictions failed, error id: 6d821ce1-23fd-4d88-8f63-992b6453830a-1: com.oracle.svm.core.jdk.UnsupportedFeatureError: Code that was considered unreachable by closed-world analysis was reached.
Try to register the following reflection classes (DiseaseAreaReport and all inner classes) as Amadeus will use GSON and therefore also Java reflection to apply the JSON String data to the DiseaseAreaReport POJO.

I hope this fixes this issue, if not dig deeper which classes or inner classes are missing to be registered for reflection with a debugger or following the stack trace.
P.S. your test shows the following warnings:

Getting the following exception while using reactive hibernate (quarkus-hibernate-reactive-panache) with reactive MySQL client (quarkus-reactive-mysql-client), kindly suggests what could be the issue.

Some details

quarkus.datasource.reactive.url=mysql://localhost:3306/mydb

My Repository Implementation
#ApplicationScoped public class EventRepository implements PanacheRepository<Event> {

Change your application.properties to

quarkus.datasource.username=root
quarkus.datasource.password=root
quarkus.datasource.reactive.url=vertx-reactive:mysql://localhost:3306/mydb
quarkus.datasource.reactive.max-size=20
Here is the cause of the problem -> I used property "quarkus.hibernate-orm.database.generation=update". It seems like the use of this property requires JDBC connection, removed it, and it's working fine.
Any of the below config sets can work.
quarkus.datasource.db-kind=mysql
quarkus.datasource.username=****
quarkus.datasource.password=****
quarkus.datasource.reactive.url=mysql://localhost:3306/db
or
quarkus.datasource.reactive.url=vertx-reactive:mysql://localhost:3306/db
"The latest version available of Hibernate Reactive doesn't support schema update and validation yet."

Can you try to add the following property to your settings?
quarkus.hibernate-orm.database.generation=update
You can write drop-and-create to re-create your db when you run your server as well. See details here.
Hmm. JDBC and Hibernate update should work in your case. Do you have a JDBC extension (dependency) in your project? If not, try to ad one.
In case of a postgres you can add extension this way:
./mvnw quarkus:add-extension -Dextensions="jdbc-postgresql
More info here
Add the agroal extension plus one of jdbc-db2, jdbc-derby, jdbc-h2, jdbc-mariadb, jdbc-mssql, jdbc-mysql, jdbc-oracle or jdbc-postgresql.
https://quarkus.io/guides/datasource
Add this dependency to your pom.xml file.

I am quite new to groovy and am quite confused about the Groovy java.sql.SQLException that I'm getting.
Here is my code
// https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc
#Grapes(
#Grab(group='com.microsoft.sqlserver', module='mssql-jdbc', version='7.2.2.jre8')
)
import groovy.sql.*
def username = xxx, password = yyy
// Create connection to MSSQL with classic JDBC DriverManager.
def db = Sql.newInstance("jdbc:sqlserver://localhost:1433;database=tempdb;", username, password, 'com.microsoft.sqlserver.jdbc.SQLServerDriver')
The same SQL JDBC Connection string ("jdbc:sqlserver://localhost:1433;database=tempdb;", 'com.microsoft.sqlserver.jdbc.SQLServerDriver') works just fine for my other cases, like Java or JMeter, but not works with groovy. This is what I'm getting:
> groovy groovy-sql-test.groovy
Picked up _JAVA_OPTIONS: -Xms512M -Xmx1g
Caught: java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost:1433;database=tempdb;
java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost:1433;database=tempdb;
at groovy-sql-0.run(groovy-sql-0.groovy:11)
This is running under Win10.
I've also tried
groovy -cp D:\path\to\my\jars groovy-sql-test.groovy
where within the D:\path\to\my\jars dir, I'm having both sqljdbc41.jar and mssql-jdbc-7.2.2.jre8.jar files.
You have to use #GrabConfig(systemClassLoader=true) to use the system
classloader and thus get the jdbc driver picked up.
From https://groovy-lang.org/databases.html#_connecting_using_grab
The #GrabConfig statement is necessary to make sure the system
classloader is used. This ensures that the driver classes and system
classes like java.sql.DriverManager are in the same classloader.
I'm running into problems with JMS in Oracle AS 10.1.3.3.
The error I am getting is 'connectors\ojms.rar (The system cannot find the path specified)' from EM.
Below are a few bullets on the environment.
This is on a Windows XP SP3 machine.
All configuration is through EM.
The EM is a local instance that has been used for over a year.
This instance has existing db connection management exposed through JNDI.
Oracle_home is set to the directory where I unzip the OC4J zip file. c:\oc4j_10.1.3.3.
ojms.rar file is in %ORACLE_HOME%\j2ee\home\connectors
Configuring OC4J for JMS with Database Persistence
I've create a new data connection for Oracle AQ and exposed the connection through JNDI as jms/flexc
When creating the Resource Adapter through EM, I'm providing the following information:
Resource Name: JMS on FlexC
Adding a new resource
Name : jmsFlexc
Datasource JNDI : jms/flexc (selected from dropdown box)
Very quickly, I get the error below:
An error has occurred.
connectors\ojms.rar (The system cannot find the path specified)

Discovered that this is a bug in OC4J.
The solution was found by a colleague as a comment made to this blog
I also got an error when deploying the
resource adapter. I found that this
was a bug in Oracle Standalone
10.1.3.3.0 (bug 6786060 on Metalink) and can be solved either by using
10.1.3.2.0 or by starting Oracle standalone without the ORACLE_HOME
environment variable. This is made by
the command "java -jar oc4j.jar". I
used the last solution and it worked
fine for me.
