Example working on Eclipse, but causing ClassNotFoundException on EC2 Centos

[hfeischl]

I am trying your sample code and it works fine when running it on my mac in eclipse using spring boot. However, when I deploy the jar file to AWS EC2 it can't find the compiler.

here is the exception I get:

nested exception is java.lang.AssertionError: java.lang.ClassNotFoundException: com.sun.tools.javac.api.JavacTool] with root cause

I am running OpenJDK Runtime Environment (build 1.8.0_242-b08) on my EC2 instance.

Any thoughts of what I am doing wrong?

Thanks!
H

[adamlalikos]

@hfeischl please review OpenHFT/Chronicle-Map#91.

EC2 is probably just running the JRE, Java-Runtime-Compiler needs the JDK (compile tools). You can probably set this up with some ebextensions work.

On top of that, my experience running within Docker / containers, you will probably need to extract the lib / classes from the spring boot jar, put them in a known location, and give these locations to the compiler classpath.

[hfeischl]

Thanks Adam,

I thought that too. But when I run java -version I get:
OpenJDK Runtime Environment (build 1.8.0_242-b08) .. sounds ok, or?

I feel like it's some java setting, or class path setting, but I am not too familiar how to configure that. I did include the following dependency into my pom.xml:

	<dependency>
		<groupId>com.sun</groupId>
		<artifactId>tools</artifactId>
		<version>1.8</version>
		<scope>system</scope>
		<systemPath>${java.home}/../lib/tools.jar</systemPath>
	</dependency>

which provides the tools.jar file to the maven dependency folder. This tools.jar file includes the com.sun.tools.javac.api.JavacTool class (the one the exception says it can't find)
So the class is there, it just can't find it, which makes me think your suggestion about a "known folder location" might be the right direction.

how do you enter a known jar folder location to the compiler classpath? do I do this in eclipse? or is there a Java config setting on the server when I need to do that?

Please ask questions on stack overflow rather than raising issues here. Are you using the oracle JDK on AWS, rather than the JRE? Rob

@hfeischl CompilerUtils.addClassPath should do the trick.

[hfeischl]

Thank you Adam.
Quick question on CompilerUtils.addClassPath. Is the input the directory string + the jar file name?
e.g.: CompilerUtils.addClassPath("/home/myapp/lib/tools.jar")
or just the directory string CompilerUtils.addClassPath("/home/myapp/lib/") ?

From my experience it’s been two things:

1. A directory that holds your JARs compiled classes.
2. A directory that holds your JAR dependencies.

For docker (not exactly your situation) I’d unzip the Spring Boot JAR and copy the classes to one folder and dependencies to another. I’d then give both folders to the CompilerUtils

The fact it tells you you're using "OpenJDK Runtime Environment" doesn't mean you're using JDK. Most likely, it's contrary - you're running JRE.

Check the output of yum list installed | grep openjdk, I bet you will not see java-1.8.0-openjdk-devel.x86_64 entry which is a JDK, but instead you will only see:

java-1.8.0-openjdk.x86_64             1:1.8.0.222.b10-0.amzn2.0.1    @amzn2-core
java-1.8.0-openjdk-headless.x86_64    1:1.8.0.222.b10-0.amzn2.0.1    @amzn2-core

both are JRE, not JDK.

So your answer is - install java-1.8.0-openjdk-devel.x86_64 (and probably have a look here for more details)
