Reinstalled Spring library
Two different way to call beans
Can someone suggested whats wrong in my system??

You might use a default package, right? I have had the same error as you...
Listen, dude, you can try to click: your project name-properties-java build path, move your external jar(s) from module-path to classpath. Then, you can run the code again.

FindException in connecting with Mysql database

I'm using ubuntu system, and using Mysql 8.0. I trying to connect database with jdbc class but having an error,although I added the mysql-connector.jar file,
The error I mentioned below,
-->Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: /home/surya/eclipse-workspace/Advancedjava/bin
Caused by: java.lang.module.InvalidModuleDescriptorException:
mysql_conntn.class found in top-level directory (unnamed package not allowed in module)
You have a module-info.java in your project making it a modular Java project. However, you also have a class (mysql_conntn) in the default (unnamed) package, and this is not allowed in a modular project.
Either you need to make your project non-modular by removing module-info.java, or you need to move the class mysql_conntn to a named package.

Why am I getting this error in eclipse involving initialization of boot layer?

I am trying to set up my eclipse environment for the sedgewick algorithms course and I keep receiving the following error:
Error occurred during initialization of boot layer

Caused by: java.lang.module.InvalidModuleDescriptorException: TestAlgs4.class found in top-level directory (unnamed package not allowed in module)
Why is this happening and how do I fix this?
And the image is attached. I created a class Rational under the default package in source.

Spring Error occurred during initialization of boot layer In Eclipse

when I download the files of Spring and added them to eclipse I get this error for the "Hello World" project;
Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for C:\Program
Files\eclipse\spring-framework-5.1.9.RELEASE\libs\spring-context-indexer-5.1.9.RELEASE-sources.jar
Caused by: java.lang.module.InvalidModuleDescriptorException: Provider class
org.springframework.context.index.processor.CandidateComponentsIndexer not in module
follow those steps to solve the problem;
1- download the lastes version of Spring in her (in my case it was, "5.2.0.RELEASE/ 30-Sep-2019 09:06") chose the spring-X.x.x.RELEASE-dist.zip.
2- Unzip the files.
3- in eclipse add extranl jars Steps In the Libs folder, don't take the ones with spring-xxx-X.x.x.RELEASE-sources.
4- done.

Could not initialize class java.util.logging.LogManager

Why do I get this error. I get it in my develpment tool when I run my code as a java application (IBM RSA\Eclipse) and in my isolated deployment environment.
I can run junits against the code and they are successful so I know that parsing the particular application context file is not a problem (web service application context). The same jre and maven dependencies are on the classpath for junit and running java application.
I know cxf uses java logger by default but adding this command doesn't help,
System.setProperty("org.apache.cxf.Logger", "org.apache.cxf.common.logging.Log4jLogger");
If I debug the code I see that the issue is raised when the application context files are parsed.
Caused by: org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.cxf.jaxws.spring.NamespaceHandler] for namespace [http://cxf.apache.org/jaxws]: problem with handler class file or dependent class; nested exception is java.lang.NoClassDefFoundError: Could not initialize class java.util.logging.LogManager
The solution was to add this System property and provide the default file when running as a java app.
System.setProperty("java.util.logging.config.file", "/log/logging.properties");

Now I have another problem but similar in nature so hopefully I can find a similar solution.

Uncaught Error: [$injector:modulerr] Failed to instantiate module due to: Error: [$injector:nomod] Module

On a Weblogic portal I am getting error.
Details - not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
How to overcome this, as my url is showing some different content ?
It is because you failed to instantiate a module or inject a dependency that you are using.
