Hi! We have some library, that we use in our web applications. We put jars of this library into WEB-INF/lib directory of each application.
But the library is in permanently development, so we have new and new versions of it every several months. Sometimes it is not backward compatible. So we need old applications work with old version of library and new -- with new. Is it possible? Wouldn't these files interfere? We have same classnames in different versions of library. Does one applicationa is totally separated from other in the sense of names of classes? It seems to me, that we meet some interferention here. We got an exception about some signature: java.lang.VerifyError: (class: com/vsetech/vtv/data/MetSystem, method: initMetSystem signature: (ZZLjava/lang/String;Ljava/lang/String;Ljava/lang/String;)V) Incompatible object argument for function call at com.vsetech.webmet.metservlet.MetServlet.MetServletInit(MetServlet.java:39) at com.vsetech.webmet.metservlet.MetTemplateServlet.init(MetTemplateServlet.jav a:22) at javax.servlet.GenericServlet.init(GenericServlet.java:256) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:93 5) ... What is it? Thanks.
