I have designed a project Database Migration.
While I run it from netbeans directly it executes properly, but when I use its jar - which is created by netbeans - then it gives an exception
com.mysql.jdbc.Driver not found
pls help me
You need to put the JDBC driver at the path. It is working in Netbeans, because it has configured it for you. Search how to set JDBC driver by downloading it from MySQl.
download the mysql jdbc driver jar and copy it the lib folder

I am trying to run the example as per the Link below, step by step:
https://dzone.com/articles/easy-java-ee-microservices-with-payara-micro
The example makes use of Apache Derby DB that I have included in Maven POM and also gets bundled in the WEB-INF/lib folder of the War file.
However, when I try to run the application with command
sudo java -jar payara-micro-5.2020.4.jar --deploy <path to>/SampleService-1.0.war
I get the following error:
javax.resource.ResourceException: The driver could not be loaded: org.apache.derby.jdbc.ClientDriver```
It may be a class loading order problem. Check out https://docs.payara.fish/community/docs/5.201/documentation/payara-server/classloading.html
Derby has been removed starting from version 5.201. Check out https://docs.payara.fish/community/docs/5.2020.4/documentation/payara-micro/h2/h2.html
Use the exact same versions in your example tutorial or use H2 instead of Derby.
Finally check out "Adding Third-Party JARs to a Micro Instance" https://docs.payara.fish/community/docs/5.201/documentation/payara-micro/adding-jars.html
I have a Spring Boot application using Flyway Migrations. Everything runs fine, from:
within IntelliJ
from the terminal on my macbook
With 'fine' I mean, migration files are found, which are placed in src/main/resources and end up in the Spring Boot executable jar.
However, when I run the jar from the commandline on Centos 6.8, Flyway is unable to find the migration files.
Any ideas?
Using Java 8.
The easiest way to resolve it is to open at your logger the package org.flywaydb to loglevel DEBUG and retry. For sure you'll find the initial clue.
Good luck
I am trying to use JMeter the first time, In my test I need to connect to informix DB.
I set driver as on the picture:
However, when I run I get error:
Response message: java.sql.SQLException: Cannot create JDBC driver of class...
I think that may be I need to provide the jar file with the driver somehow. But I do not know how to do it or may be it is another reason for the problem.
Please advise.
You need to add ifxjdbc.jar to JMeter lib folder
You can download from link see more in informix jdbc driver.
You can also get new Informix JDBC drivers from maven.
Gradle
compile group: 'com.ibm.informix', name: 'jdbc', version: '4.10.9'
Maven
<dependency>
<groupId>com.ibm.informix</groupId>
<artifactId>jdbc</artifactId>
<version>4.10.9</version>
</dependency>
So I have a grails 2.0.4 application that works exactly the way I want. I created the war file and deployed it to Tomcat 7. I'm getting an error saying that the application can't find the jar I'm using to connect to oracle (ojdbc6.jar). The jar is listed under mywebapp/WEB-INF/lib. WHY can't it be found?? Any help would be greatly appreciated!
The jar file should be in the toplevel lib directory of your project (or specified as a dependency in a repository), not webapp/WEB-INF/lib. Is the jar file actually inside the warfile? You can test this by opening the war as a zip file, or by running jar tf target/mywebapp*.war and looking for ojdbc6.jar. If it is, it should get deployed and you should see it in tomcat7/webapps/mywebapp/WEB-INF/lib.
The default environment for grails war is production instead of development. Make sure you've got the production data source configured correctly in grails-app/conf/DataSource.groovy
When running the embedded glassfish plugin I get the following message.
INFO: Cannot find javadb client jar file, derby jdbc driver will not be available by default.
How to provide the javadb client jar file?
