java - ClassNotFoundException while running jar -


i getting classnotfoundexception when try run jar whith below command:

java -jar myjar.jar

i created jar eclipe. myjar depends of couple of other jars. saw in ecplise these other jars there in classpath.

i added these jars classpath in unix using export classpath. still classnotfoundexception.

exception stack trace:

exception in thread "main" java.lang.noclassdeffounderror: org.apache.hadoop.conf.configuration     @ com.a.hdfscopy.readuri(hdfscopy.java:16)     @ com.a.copymain.main(copymain.java:9) caused by: java.lang.classnotfoundexception: org.apache.hadoop.conf.configuration         @ java.net.urlclassloader.findclass(urlclassloader.java:434)         @ java.lang.classloader.loadclass(classloader.java:660)         @ sun.misc.launcher$appclassloader.loadclass(launcher.java:358)         @ java.lang.classloader.loadclass(classloader.java:626)         ... 2 more

class path before:

/opt/ibm/biginsights/ihc/lib/biginsights-gpfs-1.1.1.jar:/opt/ibm/biginsights/ihc/hadoop-core.jar:

class path after (included locations of jars needed dependencies) :

[biadmin@big-instght-15 ~]$ echo $classpath /opt/ibm/biginsights/ihc/lib/biginsights-gpfs-1.1.1.jar:/opt/ibm/biginsights/ihc/hadoop-core.jar::/home/biadmin/hadoop_jars/commons-logging-1.1.1.jar:/home/biadmin/hadoop_jars/commons-configuration-1.8.jar:/home/biadmin/hadoop_jars/commons-lang-2.4.jar

but, realized if open new terminal , echo $classpath, displays class path before. doesn't reflect changes made classpath. i.e. doesn't show class path after.

how fix this?

thanks,

what main class listed in manifest.mf? if unjar jar, in jarfile in correct location?

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

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
