Java Manta Environment Setup

Java Manta Environment Setup

  1. Install JVM (for now, let's use Java 8). For a certified OpenJDK build, I like to install Azul's Zulu. However, be sure to install the JVM Cryptographic extensions in order to support client side encryption. For Zulu, see: Zulu Cryptography Extension Kit.

  2. Install Maven into your path. If you are using Ubuntu, apt-get install maven is all that you need to do.

  3. Install IntelliJ. You can use the free community edition because the SDK doesn't need the features in the fancy version.

  4. After IntelliJ is installed, go to plugins and install the Error-prone Compiler Integration.

Installing the Oracle Java 8 JDK on SmartOS

  1. Go to:
  2. Download the "Solaris x64 XX.X MB jdk-8u66-solaris-x64.tar.gz" tarball from the Oracle Java SE site. You won't be able to paste the URL into curl on your SmartOS instance unless you click it first to get the authentication parameter. Regardless, get the tarball any way that you prefer and copy it onto your SmartOS instance.
  3. Extract the tarball and copy it to the location of your choosing.
  4. Globally set the value of the environment variable JAVA_HOME to the path of the JVM.
  5. Update your PATH to include the Java bin directory by setting it to PATH=$PATH:$JAVA_HOME/bin

MDB is unlike most debuggers you've experienced.

It is not a source level debugger like gdb or lldb or even Node's builtin debugger

Generally used for postmortem analysis.

Postmortem is for Production and Development

We operate mostly on core files, though you can attach to running processes as well.
