QUESTION
I am trying to create an embedded jetty server with JNDI. But somehow before start up I get the below error after i do mvn jetty:run.
I see all steps are completed but before server starts I get this error
...ANSWER
Answered 2021-Jun-25 at 11:15The class you specified oracle.jdbc.driver.OracleDriver
.
Does not implement the javax.sql.DataSource
interface that is required for this org.eclipse.jetty.plus.jndi.Resource
.
You have many class options, depending on your version of Oracle server installed, your version of oracle jdbc jar file, and if you have other requirements (like transactions, pooling, etc.).
Just pick the correct class for the line (that's what's wrong with your current setup)
QUESTION
I have recently implemented a JFreeChart library in my program, but I struggle to change some of the colors of the text, so I can use it in my dark theme. The screenshot below highlights the labels I was not able to figure out how to change the color of.
I am using java swing library with the latest version of JFreeChart and JCommon
If there is any way of changing those colors to some brighter colors, I would be really glad.
Thanks everybody for their answers, I really appreciate any kind of help with this problem. This is the image showing which parts of the chart I want to change the color of the text.

on the Axis
that you want.
QUESTION
I was trying to integrate iText in my Android Studio project when the sync successfully completed.
Then I wrote some code and tried to build and test it when it gave an error (A huge one) that duplicate classes were found in same jars of different versions. (I have removed some because there were a lot)
ANSWER
Answered 2020-Aug-18 at 12:10Thanks to the guys in the comments, I could solve the problem quite easily.
What i did was ran gradlew app:dependencies
and it gave me a dependency tree.
From that tree i could make out which parts of the library required which transitive dependencies and i excluded the jcommon library of the lower version which did not have any other dependencies using:
exclude group: 'jfree', module: 'jcommon'
QUESTION
I have to migrate an old project based on spring-MVC 3 to spring boot 2 (spring-MVC 5). I have created a project from scratch with spring initializr, then I've copied files into the new project. DB used is oracle and as ORM, mybatis. When running the mvn spring-boot:run
, I received an error about hibernate:
ANSWER
Answered 2020-Mar-10 at 06:52Your pom contains way to much, it contains conflicting jars and it is even mixing jars from different versions of frameworks (Spring, Spring Boot, Axis, etc.) all that is trouble waiting to happen.
All of this comes from the simple fact you are trying to update to much at a time. When upgrading take small steps, so that you know what breaks what, as explained here.
That being said cleanup your pom.
- Remove
commons-logging
- Remove
slf4j
dependencies - Remove
spring-jdbc
- Remove
spring-orm
usespring-data-starter-jpa
instead - Fix versions for Axis
- Fix versions of Spring Boot dependencies
- Remove
aopalliance
- Remove
cglib
- Remove
jackson
dependencies as those aren't supported by Spring (and are already included inspring-boot-starter-web
. - Use
spring-boot-starter-mail
instead ofjavax.mail
dependencies - log4j isn't supported and adding a dependency on a 1.3.8 spring boot version in a 2.2.4 app is trouble. Either use log4j2 or the default logback.
- Use the default HikariCP connection pool, excluding tomcat doesn't help as it isn't included, just stick with the defaults.
- There are a ton of XML marshallers, JAXB, XMLBEans, Jibx and all are included in your app, which is it you are using?
spring-boot-starter-aop
already includes the AspectJ dependenciesspring-security-rsa
points to an old Spring Security version, you might want to upgrade to 1.0.9- Use the MyBatis Spring Boot starter instead of seperate dependencies
Here is a, partially, cleaned up pom.xml
. I haven't fixed versions or removed xml marshallers. I did remove slf4j
, log4j
and the different spring-jdbc
/spring-orm
dependencies. As well as the jackson
ones. I also grouped the Spring Boot dependencies together at the top.
QUESTION
I work with a multi-module gradle project (12 modules). I inherited the project and I need to update the versions of some libraries used in it.
I am trying to switch to using the hibernate-core version 5.4.10.Final. I can’t understand the cause of this error:
...ANSWER
Answered 2020-Jan-17 at 04:53Thanks to @StanislavL for the tip! If you change the version of the used hibernate-search module to "5.4.0. Final", the error disappears. I have not tested newer versions yet.

Install jcommon
You can use jcommon like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jcommon component as you would do with any other Java program.
