Unable to start Neo4j on Windows, no error messages

[Robo]

Sorry if this question is more appropriate at StackOverflow, but I'm having trouble getting Neo4j installed, and I'm not getting responses at StackOverflow. I don't know where else to ask, so I'm hoping someone here could help.

I'm using the following on Windows 7:

• neo4j-community-1.9.2
• Java 7 Update 25

I have Windows Firewall disabled.

When I start Neo4j.bat, both as Administrator and normally, I get the following message:

c:\Tools\neo4j\bin>Neo4j.bat 
28/07/13 9:34:27 PM org.neo4j.server.AbstractNeoServer INFO: Setting startup tim 
eout to: 120000ms based on -1

A blank Java console window pops up, no messages, then the window disappears after a minute or so.

When I go to http://localhost:7474/, I just get a server not found error.

If I try to install it as a service, the service wouldn't start.

Any ideas what I need to do to start Neo4j? I see here that Neo4j 1.9 does support Java 7:

http://blog.neo4j.org/2013/03/neo4j-19m05-released-wrapping-up.html

base.bat correctly points to windows-service-wrapper-5.jar, so not the windows-service-wrapper-*.jar problem that some people have had in the past. It would be helpful if it outputted an error message.

I tried using the console parameter, and it didn't showed any additional messages.

I just tried it with neo4j 2.0 milestone, and it didn't make any difference. The Java window pops up with no messages, http://localhost:7474/ gets a server not found error, then the Java window closes after a minute or two. i.e. same result as 1.9.

I added JAVA_HOME and JRE_HOME system variables, made no difference. I think I would get an error if Neo4j was not able to locate Java anyway.

Can you check data/logs/*.log and data/graph.db/messages.log for error messages?

Thanks a lot

Michael

Thank you very much. I've fixed it.

The log indicated the following error:

Caused by: java.rmi.server.ExportException: Port already in use: 1337; nested exception is:
    java.net.BindException: Address already in use: JVM_Bind

The port was used by Apache, once I stopped my web server localhost:7474 worked. I then found out port 1337 is used by Neo4j's remote shell, I disabled it by adding enable_remote_shell = false to neo4j.properties, then I was able to have both Neo4j and Apache running.

Thanks for letting me know the location of the logs.
