Hello, I can see from the archives that this question has come up before, but I can't find an answer to it. Apologies if I missed one.
I'm trying to hot deploy a web context that uses a JNI library. I'm using jetty-6.1.26, but I can switch versions if necessary. The library is scalaqlite [1]. The first time I start jetty, the library loads fine and works. But if I touch contexts/foo.xml, reloading the app, the next access causes an exception: java.lang.UnsatisfiedLinkError: Native Library /home/srhea/src/foo/lib/libscalaqlite.so already loaded in another classloader libscalaqlite.so contains the JNI implementation of the Sqlite3C class, which is written in Java. I've tried a number of things to fix this. Setting <Set name="parentLoaderPriority">true</Set> in jetty.xml causes the JVM (1.6.0_22-b04, although 1.5.0_22-b03 crashes as well) to crash with this error: # A fatal error has been detected by the Java Runtime Environment: # SIGSEGV (0xb) at pc=0x6ef1adcc, pid=10998, tid=1852078992 I also tried calling setSystemClasses to include Sqlite3C [2], but that caused another JVM crash: *** glibc detected *** /home/srhea/src/jdk1.6.0_22/bin/java: munmap_chunk(): invalid pointer: 0x6e310b44 *** Am I missing something obvious? Or do people just not do this sort of thing? Also, if you'd like me to put together a small webapp that demonstrates the problem, just let me know. It shouldn't take long. Thanks in advance for any help you can provide, Sean 1. https://github.com/srhea/scalaqlite 2. The full command in my jetty.xml was: <Set name="systemClasses"> <Array type="java.lang.String"> <Item>java.</Item> <Item>javax.servlet.</Item> <Item>javax.xml.</Item> <Item>org.mortbay.</Item> <Item>org.xml.</Item> <Item>org.w3c.</Item> <Item>org.apache.commons.logging.</Item> <Item>org.apache.log4j.</Item> <Item>Sqlite3C</Item> </Array> </Set> -- "I refuse to accept the idea that the ‘isness’ of man’s present nature makes him morally incapable of reaching up for the eternal ‘oughtness’ that forever confronts him." --MLK _______________________________________________ jetty-users mailing list [email protected] https://dev.eclipse.org/mailman/listinfo/jetty-users
