Installation issues: javax/transaction/SystemException

[gsingh93]

Installing this project has been incredibly painful. I've tried Neo4j versions 2.3.10 and 2.1.8, as well as two different gremlin plugins. I also had to install an older version of py2neo. I am using Ubuntu 14.04.

I eventually gave up and tried this docker container: https://hub.docker.com/r/mckeimic/joern/

After all that, I still can't get gremlin to work. I keep getting: py2neo.error.NoClassDefFoundError: javax/transaction/SystemException

I've read online about Neo4j removing the JTA requirement, but I download the JTA JAR file anyway and threw it in the gremlin plugin folder hoping it would help, but then I got other errors.

How can I fix this error? I know the errors are not in the Joern codebase, but I've been trying to install this project all day, and I think the installation instructions are really out of date.

Somewhat related, but can you provide either a Vagrantfile or Dockerfile that will properly setup the environment?

Can I get some help here @malteskoruppa?

For other users who find themsevles unable to install joern: build the dev branch. It will run on an up to date Debian (March 2018).
The dev branch documentation is available at http://joern.readthedocs.io/en/dev/

@juhakivekas Have you encountered this error? I'm following the dev branch procedures.

$ joern-import testCode.tar.gz
Creating project: testCode.tar.gz
Uploading file: testCode.tar.gz
Executing importer plugin
Runtime Exception: Input is not in the .gz format

$ file testCode.tar.gz
testCode.tar.gz: POSIX tar archive (GNU)

I can skip this step by manually parsing correctly via: $ ./joern-parse testCode
But it doesn't appear to load it into the database then. No response from the server and: [MissingPropertyException] No such property: V for class: org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource

Did you use tar czf foo.tar.gz code-root/ to create the archive? It looks like you might have forgotten the x flag to tell tar to also gzip the contents of the arcive? The file command should return this for a gzipped archive:

foo.tar.gz: gzip compressed data, last modified: Thu Mar 29 17:38:17 2018, from Unix

Yep, correct... It took me far too long to realize that issue because I was following the Joern docs... =)
