使用 JCO3 在 Java 中创建 WebService

Question

Hi people im trying to implement a webService in java wich uses JCO3 library.

i have exported as a WAR into webapps FOLDER on a server, but when i try tu run on a Server(Tomcat 7) on windows 7 32 bits.

It's a web dynamic project. And i use a sap library called (sapjco3.jar, this jar brings a sapjco3.dll). and also a json-simple-1.1.1.jar.

appears the nexts error:

When using eclipse to build a war file, be sure to have all required runtime libraries and project dependencies in the "Deployment Assemblies" (Project Properties).

For Dynamic Web Projects the class path is only used to compile your source code. The deployment assemblies will be packed as jar files into the WEB-INF/lib folder inside your WAR-File.
