| Summary: | 0000168: misleading error message when filter class refers to a class not found | ||||
| Description: |
RSN-168 When a filter class is referring to another class that cannot be found in CLASSPATH, Resin will complain that the filter class does not have a default constructor with an error message like this: "[22:45:36.619] com.caucho.config.LineConfigException: WEB-INF/web.xml:108: com.caucho.util.RegistryException: org.jpenguin.security.CheckLoginFilter must have a public zero-arg constructor." When I insert a printStackTrace in this block: try { zero = cl.getConstructor(new Class[0]); System.out.println ("Constr: " + zero); } catch (Throwable e) { e.printStackTrace(); } We can see the real reason is class not found, from the stack: java.lang.NoClassDefFoundError: org/apache/regexp/RESyntaxException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2328) at java.lang.Class.getConstructor0(Class.java:2640) at java.lang.Class.getConstructor(Class.java:1629) at com.caucho.util.BeanUtil.validateClass(BeanUtil.java:548) at com.caucho.server.dispatch.FilterConfigImpl.setFilterClass(FilterConfigImpl.java:90) ..... |
