http://issues.apache.org/bugzilla/show_bug.cgi?id=38875 Summary: Misleading error message when there are problems loading APR libraries Product: Tomcat 5 Version: 5.5.15 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] We recently rebuilt APR during an OS reinstall. After this, Tomcat failed to load the tcnative libraries: INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /x1/opt/tomcat-5.5/tomcat/bin/tomcat-native-1.1.2/jni/native/.libs However the libraries were definitely present there. Eventually I poked around in AprLifecycleListener.java, and found that the code initializing the APR library: try { String methodName = "initialize"; Class paramTypes[] = new Class[1]; paramTypes[0] = String.class; Object paramValues[] = new Object[1]; paramValues[0] = null; Class clazz = Class.forName("org.apache.tomcat.jni.Library"); Method method = clazz.getMethod(methodName, paramTypes); method.invoke(null, paramValues); major = clazz.getField("TCN_MAJOR_VERSION").getInt(null); minor = clazz.getField("TCN_MINOR_VERSION").getInt(null); patch = clazz.getField("TCN_PATCH_VERSION").getInt(null); } catch (Throwable t) { if (!log.isDebugEnabled()) { log.info(sm.getString("aprListener.aprInit", System.getProperty("java.library.path"))); ... You see it catches a Throwable, and *assumes* it means the library isn't present. In my case this was not so. When I added a log.error() to print the Throwable, I got: SEVERE: java.lang.reflect.InvocationTargetException java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.core.AprLifecycleListener.lifecycleEvent(AprLifecycleListener.java:80) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:766) at org.apache.catalina.startup.Catalina.load(Catalina.java:503) at org.apache.catalina.startup.Catalina.load(Catalina.java:523) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:247) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:412) Caused by: java.lang.UnsatisfiedLinkError: /x1/opt/tomcat-5.5/apache-tomcat-5.5.15/bin/tomcat-native-1.1.2/jni/native/.libs/libtcnative-1.so.0.2.2: /usr/local/apr-install/1.2.2/lib/libapr-1.so.0: undefined symbol: sock_is_ipv6, no libtcnative-1 in java.library.path(/x1/opt/tomcat-5.5/tomcat/bin/tomcat-native-1.1.2/jni/native/.libs) at org.apache.tomcat.jni.Library.<init>(Library.java:55) at org.apache.tomcat.jni.Library.initialize(Library.java:156) ... 15 more For the record, this is apparently a bug in APR 1.2.2 triggered when it is compiled with --disable-ipv6. It would be good if Tomcat could catch the specific exception thrown when the file is not found, and print all others, like this. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
