common jars for all JSP applications in tomcat in linux
 

I have different applications using spajco.jar

I have this jars in web-inf/lib folder of all the applications used like struts,log4j,servlet,sapjco.jar…etc...



But I get this error sometimes.



SO to have one JCO instance for one JVM instance I need to moved them to $CATALINA_BASE/common/lib





Exception: Exception in thread "main" java.lang.ExceptionInInitializerError: Could not load middleware layer “com.sap.mw.jco.rfc.MiddlewareRFC”

Native library /usr/local/sapjco/libsapjcorfc.so already loaded in another classloder.



My questions is where is the correct folder to have the common jar files which are shared across multiple applications



$CATALINA_BASE/shared/lib or $CATALINA_BASE/common/lib.



Alternatively is it not possible to place the common jars in one folder and have that folder path in CLASSPATH in .bashrc file.

The easiest solution, if you use an IDE such as Netbeans or Eclipse, is to add it through the IDE. Select your project in the left-side pane and right-click to add the jar.
