Response to Questions: Hi Michael and thanks for the reply, I tried your suggestionen but the return is empty. If I change the direction of the last [:KNOWS] relation to be <-- I do get a result, however that is only the other owners of the numbers I have and not the friends of the owners of the numbers that I have... Graph looks like this: A KNOWS 1 B KNOWS 1 B KNOWS 3 C KNOWS 1 C KNOWS 2 C KNOWS 3
Suggest friends of A Which (we hope would) return: 3, 2 in that particular order (based on Count?) and not including 1 which already is a KNOWS connection of A.

Try: { "order" : "depth_first", "uniqueness" : "relationship", "return_filter" : { "language" : "javascript", "body" : "position.length() > 0 && position.lastRelationship().getProperty('name').toLowerCase().indexOf('test' )!=-1"}, "max_depth" : 1 } That is, "depth first" becomes "depth_first", "return filter" becomes "return_filter", and "max depth" becomes "max_depth".

We have a graph with 4 ppl owning 5 phone numbers (some own 1 some own 2 and others 3). 1. When trying to get a list: friends of friends (that are not my own friends), I write the following query, however my own friends still show up and some entries are duplicates. START id_my=(11) MATCH (id_my)-[:KNOWS]->(f)<-[:KNOWS]->(id_o)-[:KNOWS]->(fof) WHERE NOT(f.number=fof.number) RETURN f a. How do I remove my own friends from the returning subset? b. How do I remove the duplicates in the returning array? c. How do I make sure they are prioritized in the right order? (maybe connected to the b. question) 2. Are there any resources where I can read more about how to use indexes? I mean very practical examples of how they are set up and used. Thank you guys!

To: Neo4j user discussions <[email protected]> Message-ID: <caddlr8rc1ny4b+ylu1ozwujswhgryqoykuhgzxgeuwhjjqv...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Hi Eddy, what you are missing is the JTA specification jar. You can find a copy here: http://repo1.maven.org/maven2/org/apache/geronimo/specs/geronimo-jta_1.1_spe c/1.1/geronimo-jta_1.1_spec-1.1.jar Neo4j uses maven to manage its dependencies so that such necessary libraries are located and downloaded automatically. This has the additional advantage that if you have a dependency management system as well all this will be automatically taken care for you. To get back to your questions, no, JavaEE is nowhere near needed for running neo4j. For the kernel you will need, apart from JTA above, http://repo1.maven.org/maven2/org/osgi/osgi_R4_core/1.0/osgi_R4_core-1.0.jar http://repo1.maven.org/maven2/org/osgi/osgi_R4_compendium/1.0/osgi_R4_compen dium-1.0.jar as well and you should be good to go. For the tests, junit is also needed. I don't know of a way to have these dependencies managed from the package managers that come with linux distros, so either a dependency manager or manual downloads are your options here. In general, the pom.xml in every project has a listing of all the dependencies you will need. cheers, CG On Tue, Jul 12, 2011 at 4:18 PM, Eddy Respondek <[email protected]> wrote: > I'm currently getting the following error message in Debian Lenny when > trying to run a class file. > > Exception in thread "main" java.lang.NoClassDefFoundError: > javax/transaction/TransactionManager > > As far as I can tell Debian is missing a jta.jar file which is apparently > apart Java EE 6 but this isn't one of Debian packages. > > Do I need to manually install Java EE 6 or can I get JTA.jar somewhere > separately? > > More info.... > javac -cp /usr/share/java/neo4j-kernel.jar:/usr/share/java/jta.jar > /tmp/gpneo4jimport.java > java -cp /tmp:/usr/share/java/neo4j-kernel.jar:/usr/share/java/jta.jar > gpneo4jimport > > java version "1.6.0_22" > Java(TM) SE Runtime Environment (build 1.6.0_22-b04) > Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode) > _______________________________________________ > Neo4j mailing list > [email protected] > https://lists.neo4j.org/mailman/listinfo/user > ------------------------------ Message: 7 Date: Tue, 12 Jul 2011 21:42:58 +0800 (CST) From: ??? <[email protected]> Subject: [Neo4j] how setup lucene fulltext search filter To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=GBK I like to filter fulltext search result,but don't kown where to set lucene search filter.
