export-graphml command not found in ne04j shell on windows

[vikramkone]

I'm trying to export the neo4j database as a graphml file on a windows machine. This is what I did

1. Downloaded neo4j-shell zop file from github (this repo)
2. Unzipped the *.jar files under "C:\Program Files (x86)\Neo4j Community\bin\"
3. Started the shell from command prompt after starting the neo4j instance and loading my database
4. I did this in the shell, and get unknown neo4j-sh (?)$ export-graphml Unknown command 'export-graphml'
5. Next to debug, I turned on echo in the Ne04jshell.bat file under bin and I see this

C:\Users\$$\Documents\Neo4j>java -classpath ;"";"C:\Program Files (x86)\Neo4j Community\bin \geoff-0.5.0.jar";"C:\Program Files (x86)\Neo4j Community\bin \import-tools-2.1-SNAPSHOT.jar";"C:\Prog ram Files (x86)\Neo4j Community\bin \mapdb-0.9.3.jar";"C:\Program Files (x86)\Neo4j Community\bin \neo4j-desktop-2.2.0.jar";"C:\Program Files (x86)\Neo4j Community\bin \opencsv-2.3.jar" -Dapp.name="ne o4j-shell" -Dapp.repo="C:\Program Files (x86)\Neo4j Community\bin " -Dbasedir="C:\PROGRA~2\NEO4JC~1\bin.." org.neo4j.shell.StartClient Welcome to the Neo4j Shell! Enter 'help' for a list of commands NOTE: Remote Neo4j graph database service 'shell' at port 1337

So the class path is being set correctly for all the imported jar files. But still its

put the jars in lib not bin

also there are spaces in your path's that don't belong there.

[vikramkone]

I have put the files in lib folder also ..still no luck. The spaces are generated by the .bat file, I didn't do anything special to specify the paths. Also the .bat file is looking for jar files inside bin folder not lib folder. This seems like a bug in the tool script

[jexp]

Weird, as I don't have windows, I can't test it. Perhaps you can fix the batch-file to not generate spaces?

Hi,

Following the same steps but under Ubuntu 14.04, I have the same problem. export-graphml -o out.graphml gives Unknown command 'export-graphml.

jar files are under lib/ directory and the help command in the neo4j-shell displays available commands such as import-geoff import-graphml but no export-graphml…

[jexp]

Can you check that you have the correct version that actually contains graphml-export?

jar tf import-tools-2.2.jar

should list ExportGraphML.class somewhere

[benjaminh]

org/neo4j/shell/tools/imp/ExportGraphMLApp.class appears in the list, is that the good one ?

Besides, for unknown reason, geoff-0.5.0.jar,import-tools-2.2.jar and mapdb-0.9.3.jar have different permissions compared to other jars:

• -rw-r--r-- for the 3 jars mentioned above
• -rwxr-xr-x for the others Does it matter ? I don't know the way jar files are used, are they just read or do they have to be executed ?

[jexp]

This shouldn't matter

perhaps you can check also graph.db/messages.log for any error message?

the only other thing that I could imagine but is very unlikely is that META-INF/services/org.neo4j.shell.App

in your jar

contains: org.neo4j.shell.tools.imp.ExportGraphMLApp

[benjaminh]

There is no error messages in log.

You're right, META-INF/services/org.neo4j.shell.App contains org.neo4j.shell.tools.imp.ExportGraphMLApp... If I understand, this seems like a bad news ?

[jexp]

This sounds as if it is inexplicable to me. :(

[benjaminh]

But this page shows that the line mentioned above exists. As I downloaded the zip file from github, it seems logical to me that I have the same file, isn't it ?

Yet, I have no idea what the presence of this line implies. What would happen if I delete it ? Should I open a proper issue ?

[krk]

I have the issue too.

I had to recompile the jar file in Windows. After that, the export-graphml will work. Let me know if you need a copy of the updated jar file.

[jcwill]

It doesn't work for me either. I'm on windows too.

[davidfauth]

I've uploaded an updated zip file here:

[danpaulsmith]

For neo4j 2.2.5, I had to put the jar files in libexec/lib !

Except now it just outputs "null".

Actually, got it, think it was the ordering of the flags

[koolkao]

I ran into the same issue as vikramkone on Windows. There is an extra space in the paths generated in CLASSPATH.

I manually fixed the paths and ran the generated command, but strangely the shell still cannot see the export-graphml function.
