I'm working on a project and it kept generating error when runing the project.
I need help to solve this issue please, thank you in advance.
UPDATE -------------------------------
I'm still struggling with this issue, in the beginning when i was trying to test the methods everythings works fine, all the insert, update, delete... but when i added Servlet I got these errors.
This is my first time using Maven and Hibernate and it's giving tons of errors such as
java.lang.NoClassDefFoundError: org/hibernate/query/Query at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1407) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1215)
I have tried this solution it works (the servlet works too) for a little while then back to the same problem again.

I couldn't fix the problem so I switched to Dynamic web Project, and now everything works fine, i didn't even had to change a piece of code or add other jars.
Try running an mvn dependency:tree to see what your classpath looks like.
There is a compatibility matrix between hibernate, REST and other components. That means you have to use the right versions together. It's often non-trivial to figure out which ones to combine, but mvn dependency:tree -Dverbose will give you insight where you overwrite versions. These days, most platforms have a website to generate a compatible pom for you (Quarkus, Spring, etc). But old-school war based deployments typically don't have that yet. Non-war based deployments of Hibernate with Rest look differently: here's an example.
A quick search shows that the class org.hibernate.query.Query existed in hibernate-core 5.2, but not in 5.6, where it got moved to org.hibernate:hibernate-search-orm.
Try adding a dependency on hibernate-search-orm too:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-search-orm</artifactId>
<version>5.6.0.Final</version>
</dependency>

I wanted to learn how to develop RESTful APIs with JAX-RS and so started with an example covered in one of the YouTube videos. The video was created 5 -6 years ago and used Tomcat 7 and an older version of Eclipse. But I installed the recent versions of Tomcat (10.0.6) and Eclipse (jee-2021-03) and followed the tutorial.
I created a new maven project with the following archetype:
Group Id: org.glassfish.jersey.archetypes
Artifact Id: jersey-quickstart-webapp
Version: 3.0.2
I provided Group Id and Artifact Id for my project with default version 0.0.1-SNAPSHOT and clicked Finish.
Eclipse created the project with the following 2 errors:
index.jsp: "The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path"
pom.xml: "Could not initialize class org.apache.maven.plugin.war.util.WebappStructureSerializer" on the very first line.
I'd appreciate if someone can help me understand why I'm getting these errors and how to resolve them.
Here is my pom.xml.

for first problem:
right click on your project
click Properties
click Targeted Runtimes
tick mark Apache Tomcat v10.0
click Apply and Close
for second problem:
add the following plugin inside the pom.xml file inside build -> plugins

your pom.xml file should be like this:

Is it because I'm using ${springframework.version}? I've seen from some project that this works but not to be the case in my project. Do i need to define it somewhere?
Here's the screenshot of the error.
You need to define a property named springframework.version in your maven POM. Like this
<properties>
<springframework.version>4.3.11</springframework.version>
</properties>
The scope - runtime added for spring-context dependency was the issue in pom. Once removed(runtime attribute)and maven clean install builds successfully.
As the title suggests, I'm trying to generate an HTML report of the JUnit results when my maven project executes. I was told to check out maven-surefire-report plugin by another person and it looks like it has what I'm wanting but I just can't seem to get the HTML file to generate. I'm looking to ONLY generate an HTML file that I could then put into an email for my bosses. I'm not really wanting to go down the road of having the results post to a site (at least not at the moment).
Here is what my pom section looks like for surefire (don't worry about missing tags. I'm copying and pasting the relevant sections, and trying not to paste company info, but know I have the proper opening / closing tags):
EDIT: Added full pom.

As far as I know, and according to the guides and what not I've looked at, this is all I need. Just the pom dependency and the reporting plugin section but I'm still not seeing an HTML file generated.
I have a feeling the part that I'm missing is going to be very minimal but I just can't seem to find it.
The default report should be located in ${basedir}/target/site/surefire-report.html
I believe you might need to include maven-surefire-plugin and junit in the plugins/dependencies respectively.
The surefire report plugin will automatically parse the files matching TEST-.xml in ${basedir}/target/surefire-reports but I believe you need the maven-surefire-plugin in order to generate the TEST-.xml files
Here is the documentation to the plugin. One way might be to run the build and see if the TEST-*.xml files are being generated.
http://maven.apache.org/surefire/maven-surefire-plugin/index.html
By default surfire plugin will create XML and txt files report in {base-dir}/target/surfire-reports.
to generate HTML report you can use
mvn surefire-report:report-only
above command will use XML files and will create HTML report at {base-dir/target/site/surefire-report.html}
configure as below
<configuration>
<outputDirectory>${basedir}/target/newsite</outputDirectory>
</configuration>
using stand alone tool you can change the path like below
mvn surefire-report:report -DoutputDirectory=newpath
Check if you have added your Runner-class inside Surefire plugin of the POM file:-

Afterwards, I have gotten a file MyProject-0.0.1-SNAPSHOT.jar in the target directory of the project. Double clicking on that jar in Eclipse gave me a pop-up Windows window saying "Java Virtual Machine Launcher - A java Exception has occured!". To find more about what a possible problem could be, I have copied that jar on the desktop and run java -jar MyProject-0.0.1-SNAPSHOT.jar from that. After that, I got a following error:
Assuming from the error log, I tried to search if I have included org.hibernate.cfg.NamingStrategy in my Maven repository, and yes, I do have it there. After that I got stuck. Any ideas? Thanks.
You need to create an executable fat jar: one that contains your jar dependencies as well. See: Building a fat jar using maven
You have to include all the dependencies on the classpath that are required by your code.
You can naively do this with a shell script that manually adds everything to java -cp parameter, but this is brittle and a complete fail when something changes.
The simplest way to do this is to use the shade plugin to make an uber-jar that includes all the dependencies.
Note that this won't work correctly if any of the dependencies are cryptographically signed, unfortunately the signing stuff is in the MANIFEST file in such a way that it applies globally to the entire .jar and not individual classes or packages. You would have to manually remove the signatures from the uber jar.
I've an application that uses Maven to build a JAR with the maven-assembly-plugin.
The project includes a list of dependencies and one of these is another Maven project.
I'm developing with Eclipse and when I run the project everything works fine. When I build with the Maven goal assembly:assembly, it makes the JAR but when I run the JAR it gives me this error:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:

The problem is related to the Java mail dependency. As you can see I've used com.sun.mail but I saw some other different libraries that correspond to javax.mail.
Maybe I'm missing something in my poms, such as configuration parameters or plugins.
I've also tried to put in my local repository a mail.jar that works fine in other projects but I get the same error.
The "Unresolved compilation problem" comes from a class file in your utils project that Eclipse has compiled, but where Eclipse was unable to compile it properly.
The reason you are seeing different results from Eclipse and Maven is that they are using different versions of the class file. Eclipse is doing workspace resolution, so it's using the version of SMTPMailService in utils/target/classes. Maven is resolving the utils jar from your local Maven repository, which was put there by running mvn install while you had compile errors in Eclipse.
Try running mvn clean install in the utils project (clean to remove any class files generated by Eclipse, install to replace the jar in your local repository). Then rebuild your assembly.
