HI All,
I've been going along merrily writing a Java app with the V1.7-snapshot:
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orient-commons</artifactId>
<version>1.7-SNAPSHOT</version>
<type>bundle</type>
</dependency>
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-core</artifactId>
<version>1.7-SNAPSHOT</version>
<type>bundle</type>
</dependency>
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-graphdb</artifactId>
<version>1.7-SNAPSHOT</version>
<type>jar</type>
</dependency>
<!-- FOR CONNECTING TO THE SERVER THROUGH THE REMOTE ENGINE -->
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-client</artifactId>
<version>1.7-SNAPSHOT</version>
<type>bundle</type>
</dependency>
<!-- INCLUDE THIS IF YOU'RE USING THE TINKERPOP'S BLUEPRINTS API -->
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-blueprints</artifactId>
<version>2.1.0-SNAPSHOT</version>
<type>bundle</type>
</dependency>
The graph is created by the Java application OK and for the most part seems
to be working as a "local" database using the following code:
* factory = new
OrientGraphFactory("plocal:./testGraph").setupPool(1,10);*
But, I was having some issues and wanted to take a closer look.
So, I've loaded up the Gremlin console (V 2.4.0) and when I open it up with:
* g = new OrientGraph("local:./testGraph");*
or
* g = new OrientGraph("plocal:./testGraph");*
I can't see any Vertices or Edges.
What's worse is that if I "shutdown" and exit gremlin, the next time I try
to open the graph with the Java code I get:
com.orientechnologies.orient.core.exception.OStorageException: Cannot open
local storage 'testGraph' with mode=rw

I am running on OS X and in Terminal can see the permissions - which all
look OK.
Is there a file permission I should be looking at or is there a lock of
some sort that needs cleaning up.
Ideally, I'd like to use both at the same time during testing.
I do have an Orientdb server configured and running but this is early
testing - some unit testing in fact - so I was trying to keep it as "local".
Also, I get the following error from Gremlin if I do try to connect to the
server:
gremlin> g = new OrientGraph("remote:localhost/testGraph");
Error on opening database: the engine 'remote' was not found. URL was:
remote:localhost/testGraph. Registered engines are: [plocal, local, memory]
Sorry for lumping the two questions - about Gremlin - into the same post.
-Anthony
