通过python-joern访问neo4j

Question

在使用Joern时，我使用以下代码通过python-joern访问Neo4j数据库。

from joern.all import JoernSteps
j = JoernSteps()
j.setGraphDbURL('http://localhost:7474/db/data/')
j.connectToDatabase()
res =  j.runGremlinQuery('getFunctionsByName("main")')
for r in res: print r

像这样的错误

Traceback (most recent call last):
  File "test.py", line 11, in <module>
    res =  j.runGremlinQuery('getFunctionsByName("main")')
  File "/home/binbin/Downloads/python-joern-0.3.1/joern/all.py", line 44, in runGremlinQuery
    return self.gremlin.execute(finalQuery)
  File "/usr/local/lib/python2.7/dist-packages/py2neo-2.0-py2.7-linux-x86_64.egg/py2neo/ext/gremlin/__init__.py", line 36, in execute
    response = self.resources["execute_script"].post({"script": script})
  File "/usr/local/lib/python2.7/dist-packages/py2neo-2.0-py2.7-linux-x86_64.egg/py2neo/core.py", line 288, in post
    raise_from(self.error_class(message, **content), error)
  File "/usr/local/lib/python2.7/dist-packages/py2neo-2.0-py2.7-linux-x86_64.egg/py2neo/util.py", line 215, in raise_from
    raise exception
py2neo.error.NoClassDefFoundError: javax/transaction/SystemException

如何修复它？
