Re: [Neo4j] Re: Neo4j Traversal Framework
Is it possible that Neo4j is not installed properly.
Because I probably Uninstalled neo4j and still server starts properly.
But server shows TransactionFailureException when saving object.
* I already have graph.db file, And I have some entries in it.
* When I run neo4jTemplate.count() it returns count of the objects.
* but when I save an object it shows TransactionFailureException and count
still remains same.
* code structure is as above
Can you check what problem this might be?
How do i check if Neo4j is installed properly?

Re: [Neo4j] Re: Neo4j Traversal Framework
The basic structure of the code is as above though.
Here is the code that is not working
@Service
@Transactional
public class Neo4jService
{
@Autowired
private Neo4jTemplate template;
public User addUser(User user)
{
template.save(user); //No Error Till here
return user; //After This step Error
occurs
}
}
Can it be because improper neo4j version and Spring data version

Re: [Neo4j] Re: Neo4j Traversal Framework
Best if you can share a minimal example project that reproduces the issue.
I presume that your spring config is not correct.

Re: [Neo4j] Re: Neo4j Traversal Framework
Hi,
Thanks for your help.
I Resolved The Issue. It was not Neo4j Error, it was Some other component
producing error which was causing neo4j to crash.
Now Server is starting normally.
Now I am getting Error while writing data to the database.
Code structure is as follow:
@Transactional //Imported From SpringFrameWork
@Service
public class NeoService
{
public User saveObj(User user)
{
//Some code to read database
//which works fine
user=neo4jTemplate.save(node); Works Fine till here
return user;//produces Error
'org.neo4j.graphdb.TransactionFailureException:
commit threw exception'
}
}
Can You help me find the Error

Re: [Neo4j] Re: Neo4j Traversal Framework
If you run mvn dependency:tree
You'll see that sdn pulls in neo 2.2 you should use the same version throughout

Re: [Neo4j] Re: Neo4j Traversal Framework
Thanks for response, It is amazon EC2-unix instance. I run tomcat-8 in the machine with Java-spring. Server was running fine for so many days then it suddenly started showing above error. I did not change anything like classpath etc. Even that same war file is running without errors in my windows system, but not in remote system. Can It be caused by mismatch in "NEO4J SDN" version in spring and "NEO4J" installer version. * I am attaching .classpath file here with email. * Packaging is ".war". * I put war in "/webapps" folder of tomcat and run tomcat. If you need any more information Please let me know. Thanks again. On Mon, Mar 14, 2016 at 2:18 PM, Mattias Persson wrote: > That looks like a classpath issue.

Re: [Neo4j] Re: Neo4j Traversal Framework
You're correct in principle, but it's not a new "query" as such that is
sent every time. The traversal state is kept between calls to hasNext/next,
but that's just a detail.

Re: [Neo4j] Re: Neo4j Traversal Framework
Thanks for the reply,
So you mean that for each iteration of following 'FOR' loop, a query is
sent to get next node from database if it exists.
and that not all the nodes are returned in one go before 'FOR' loop even
starts.
for(Node currentNode : database.traversalDescription()
.depthFirst()
.uniqueness(Uniqueness.NODE_GLOBAL)
.order(BranchOrderingPolicies.PREORDER_BREADTH_FIRST)
.relationships(, Direction.BOTH)
.evaluator(Evaluators.excludeStartPosition())
.traverse(node)
.nodes())
{
}
Thanks for the response again.

[Neo4j] Re: Neo4j Traversal Framework
With the traversal framework, the actual work of traversing happens lazily on every call on hasNext/next on the returned Traverser (in the end Iterator). You can simply stop pulling more paths after a certain number of paths have been extracted.
