java - JQuantlib missing extensions -

-

i working on big project requires massive financial calculations, using netbeans ide 7.3 default web application of java ee 5 (not maven application) ,my application server tomcat 7 using jsps , servlets os windows 7.

i downloaded , added jquantlib binary application, when run keeps saying needs slf4j-api extension not found download , added jar project still error persists.

how can solve ? , can give me guidelines on how ?

the key here jquantlib requires slf4j-api version 1.4.0 in jar manifest:

(from manifest.mf in jquantlib.jar)

      implementation-vendor-id: org.jquantlib     extension-list: slf4j-api     slf4j-api-extension-name: slf4j-api     slf4j-api-implementation-version: 1.4.0

tomcat try use version of slf4j-api you're including in app, it's you've included isn't compatible. see http://grepcode.com/file/repo1.maven.org/maven2/org.apache.tomcat/tomcat-catalina/7.0.34/org/apache/catalina/util/extension.java#extension.iscompatiblewith%28org.apache.catalina.util.extension%29 details.

bottom line - try use slf4j-api version 1.4.0 in application.
