i've started trialling shiro , trying code securitymanager ini resource when encountered 

java.lang.classnotfoundexception: org.apache.commons.logging.logfactory

extended message:

my code stated core.server.testshiro(server.java:121) is:

org.apache.shiro.mgt.securitymanager securitymanager = factory.getinstance();

my guess is, there issue shiro.ini file specified in previous line of code factory<org.apache.shiro.mgt.securitymanager> factory = new inisecuritymanagerfactory("classpath:shiro.ini"); , based on error message, seems beanutils library needs org.apache.commons.logging.logfactory class

my question not how correct shiro.ini, rather how solve classnotfoundexception.

note using log4j2 , have included log4j2 jars, slf4j bridging adapters (my understanding shiro need these) jars in library:

  • log4j-api-2.8.2.jar
  • log4j-core-2.8.2.jar
  • log4j-slf4j-impl-2.8.2.jar
  • slf4j-api-1.7.25.jar

as hibernate jars

i've done search , saw les hazlewood's response shiro user site's question java.lang.noclassdeffounderror: org/apache/commons/logging/logfactory @ explicitly excluding jcl. 3 options stated directed site doesn't apply not using maven-ized project, standalone java project in netbeans. however, i've tried including commons-logging-1.2.jar , jcl-over-slf4j-1.7.25.jar in lib folder (which gathered similar "provide scope" instruction site) doesn't solve exception.

i've tried including log4j-jcl-2.8.2.jar in lib folder, same exception still doesn't go away.

any , guidance appreciated. in advance! cheers.

i got same error when using shiro-web. since use slf4j add runtime dependency jcl-over-slf4j. did , resolved exception. if still error not doing right - e.g. placing jars correct location, ...

do not include commons-logging jcl bridge. either use jcl bridge slf4j or use commons-logging both not make sense.

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
