tomcat - neo4j : Limited queries sent in java -


for website developed under tomcat, connect program database neo4j. connection done through jdbc. program right local, , database on remote server. when start tomcat, first check if specifics nodes presents, , if not, creates them. there 135 nodes. problem : after ten, program stops, , stay in infinite loop. assume should close something, what? here code :

private resultset sendcommand(string command) throws sqlexception     {         try(statement statement = _neo4jconnection.createstatement())         {             return statement.executequery(command);         }     }

and function call code (all functions based on same structure)

public static long createnode(nodelabel labelname)     {         try         {             resultset rs = getinstance().sendcommand("create (n:"+labelname+") return id(n)");             long result= rs.next()?rs.getlong("id(n)"):null;             rs.close();             return result;         } catch (sqlexception e) {             e.printstacktrace();             return null;         }            }

in latest experiment reused same statement multiple times, not sure best way seems work good, too.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
