Java native library path in Tomcat web project

Question

I have a web project with some native libraries. Most of them are loaded by JNA library.

I put them in this folder

WEB-INF\classes\*.dll

of a ROOT package.

When the application starts they are loaded by Tomcat in

${catalina.home}\webapps\ROOT\WEB-INF\classes\mylibrary.dll

All libraries are founded by JNA and work, however there is just one library managed by third parties (Zebra Multilink platform SDK) that I cannot load from that folder. Maybe because it doesn't work with JNA but with JNI. If I move that libraries to

 ${catalina.home}\bin

that is the folder defined by java.library.path param in tomcat start command it works!

Can I distribute libraries in ROOT.war package and set tomcat to look into all my applications to find native libraries?

好了，您可以修改java.library.path并使其指向展开的webapp目录（您的${catalina.home}\\webapps\\ROOT\\WEB-INF\\classes\\ ，但需要自己先解析${catalina.home} ） 。
