Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

This is the plug in the war module has

  <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.3.2</version>
            </plugin>
        </plugins>
    </build>

there's probably more information before that

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

This is where it started

dan1st•9mo ago

well here are the errors

dan1st•9mo ago

literally Java compiler errors

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

but it's already there

dan1st•9mo ago

is it imported correctly?

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

yah I can even view the class by ctrl+click

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

This is the class

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

How do I check? it usually will show the compile error right? but it works perfectly fine even I can run the web app

dan1st•9mo ago

Did you run mvn install on the root project? I think maybe the web project doesn't find the other one

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

no he can't find the symbol which is the ejb.impl.ClientSessionHandlerBean any advice on what to search for further google research? but also you can see in the other package (servlet) I imported another bean from the same package

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

oh wait, so when I ctrl+click, it doesn't show me the code in the ejb package directly instead it shows the compiled class

dan1st•9mo ago

also in the mvn install command on the root project? Can you show the pom.xml of the project that fails (I think it's web, right?)

dan1st•9mo ago

Which module contains ejb.impl?

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

yah I tried this?

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

ejb

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

dan1st•9mo ago

that's the root project, right? Can you show the pom.xml of that?

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

yah ee-app

dan1st•9mo ago

also I don't know what <type>ejb-client</type> is supposed to do

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

it's for client (remotes)

dan1st•9mo ago

And in the log of the mvn install on the root project, does it list all of your modules? Are you sure it is supposed to access implementation packages then?

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

that's where it is useful I guess yah ok it's working after commenting out the type ejb client let me check one more time holly shit yah

dan1st•9mo ago

https://maven.apache.org/plugins/maven-ejb-plugin/examples/generating-ejb-client.html https://maven.apache.org/plugins/maven-ejb-plugin/examples/ejb-client-dependency.html it looks like ejb-client means you only have the stubs so no actual implementations since these are on the remote side oh and maybe if you do want <type>ejb-client</type>, you may need to add <generateClient>true</generateClient> to the <configuration> of the maven-ejb-plugin in the ejb module

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

so ejb client removes everything that is ends with Bean in the end

dan1st•9mo ago

maybe

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

this has to be it

dan1st•9mo ago

looks like it

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

Stubs means?

dan1st•9mo ago

essentially it means you just have the API, not the implementation and for the implementation, it might e.g. send it to a server which then processes it

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

This means it would used the ejb's clean compiled packaged installed jar file?

dan1st•9mo ago

When you have a dependency, it typically uses the version in your local repository (.m2/repository). This is created when doing mvn install. If none is found, it attempts to download it from a remote repository. and I guess with <type>ejb-client</type>, it looks for a -client.jar in there at the right location which is ~/.m2/repository/your/group/id/your-artifact-id/YOUR_VERSION/

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

ok and it couldn't find?

dan1st•9mo ago

? I was just telling you where it looks for the JAR IntelliJ will probably directly use the other module so you don't have to do mvn install on every change maybe that's why you got different results for IntelliJ and Maven (CLI)

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

oh ok mvn and intelij

dan1st•9mo ago

generally the Maven CLI is the source of thruth

Rag...JN 🌌 🦡 👽 💰 🐊OP•9mo ago

alright alright thank you so much

Root cause for this problem was not undertanding the dependency configuration properly
