Exception with running Neo4j version 3 communitiy edition - neo4j

I unpacked the tar file of Neo4j linux version.
When running the server (./bin start) it seems like the server is up, but I cant access the browser (although I get a message it is ready).
Running the console (./bin console) - returns an error: "Error: Could not find or load main class org.neo4j.server.CommunityEntryPoint"
Did anyone also encountered this issue? How can I solve this?
Thank you

How did you run ./bin console? I'm curious since such a thing does not exist.
To start up the database you use bin/neo4j start - then you point your browser to localhost:7474.
For command line based access use bin/neo4j-shell.

ERROR: Error CREATEing SolrCore 'hydra-development': Could not create a new core

I am trying to run solr_wrapper along with fc_wrapper to run my app.
This is how I am starting the solr,
enter code here
solr_wrapper -d solr/config/ --collection_name hydra-development --version 6.3.0
But when I hit this command, below is the error I am getting.
Failed to execute solr create: (RuntimeError)
Creating new core 'hydra-development' using command:
http://localhost:8983/solr/admin/cores?action=CREATE&name=hydra-development&instanceDir=hydra-development
I am able to start the fc_wrapper.
Can someone helpstarting the solr_wrapper.
These "solr_wrapper" and "fc_wrapper" tools do not come with Solr. Somebody else built those, so I have no idea how they work or what they do.
In order to create a core, the config must be available. See the big red box here:

grails 2.5.4 won't start from terminal StackOverflowError

I'm running grails 2.5.4(I cannot upgrade the version), it successfully runs in my IDE (intellij) but I cannot get any grails command to run from the terminal. Even if I type just "grails" and nothing else, it will throw an error.
The error is:Exception: java.lang.StackOverflowError thrown from the UncaughtExceptionHandler in thread "main"
I can't seem to get anymore information out of it with --verbose
Also, I am running java 8
so I found out what was going on through excessive trial an error. The issue was that I had db2 installed on my machine. I don't know why that was causing the issue. But for anyone that might be running into this issue, that's what the problem was for me.
We had the same problem; in our case, all it took was an empty .inputrc file in the user's home directory to make grails work.

Regarding Neoload 5.0.2

I'm getting an error msg "Load Generator Unavailable" pop up evry 2 iterations when I run the script via check virtual user.Closing and reopeing Neoload solves the issue.Could any of you please help me in resolving this issue?
This looks like it is a common issue with Neoload across versions, we have seen this across all of our windows installations where we run with localhost as a load generator or when we run with stand-alone generators. Most of the time a stop and restart of the load generators and load controllers will solve this issue. On more rare occasions a complete restart of the controller server needs to happen. This is issue is appearing in the latest version as of the date of my response.
I use to have this problem. I just needed to restart my load generator. All I did was ssh into my load generator that was acting up. Then ran sudo –u neoload /opt/neoload/bin/LoadGeneratorAgent stop then after that I would run sudo –u neoload /opt/neoload/bin/LoadGeneratorAgent start & Exit and restart neoload and I stopped having the problem. You will just replace the path with your own. This is for external load generators not local host generators.

Neo4j StartService FAILED 1053 after copying Beer DB example

I installed Neo4j as instructed in the site and was able to install and stat server. However I tried to copy the Beer example DB by stopping the server and deleting the current graph.db in the \data folder and replaced with the one Beer example downloaded from online (graph.db folder). This is the only step I did.
Now the issue is, when i tried to start the Server I get "StartService FAILED 1053"
I am using following command on the powershell in windows - c:\neo4j-community-2.0.0-M03> .\bat\Neo4j.bat start
Can someone please help if I have done anything wrong here.
Thank you!
You are running neo4j 2.0 against an older database file. You'll need to set the config parameter to allow the store to be upgraded before starting. See instructions here:

could not start the sphinx search service on local computer?

i am getting this
Windows could not start the SphinxSearch service on Local Computer.
Error 1067: The process terminated unexpectedly.
i got installation instruction from this .
http://blog.robbsnet.com/2011/07/how-to-install-and-implement-sphinx.html
build process is complete but when i start the sphinx search service i got errors .
Try running searchd manually from Command Prompt. Maybe it will give you a useful error message.
Try also looking in searchd.log
For anyone who is still having problems with the Windows service:
Make sure your configuration is correct for both database and paths and the needed folders & files are created.
Make sure that the service "command" matches the correct paths and files, to do so you have to:
Run administrative tools, click on local services, then find SphinxSearch. Click on its properties and read the line the service is trying to execute. If the configuration path doesn't match the service start command, it will fail to start.
FYI, this can also happen because your search data files are corrupt. Easy fix for that is to nuke the files and refill them.
