Sorry for replying to this so late. As an FYI, APRVARS will soon be removed from APR. Take a look at the replacement apr-config and apu-config (in apr and apr-util respectively). It's not yet complete (that's why APRVARS hasn't been removed yet), but if you see something missing let us know. -aaron -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

I think it'll work fine if LD_LIBRARY_PATH is set before starting tomcat to include all the libs ( and libapr ) or of libapr ( and the rest ) are installed in the system dirs ( i.e. /usr/lib ). It works better ;-) using System.loadLibrary() and set the LD_LIBRARY_PATH before starting the JVM solves problem of finding the path. System.loadNative(/usr/local/lib/libapr.so); could be changed into System.loadLibrary(apr); The remaing problem are the dependencies of libapr.so How to load the needed libraries? loadLibrary() does not make the symbols available to other libraries. (like dlopen(RTLD_NOW|RTLD_GLOBAL)). The code in loadNative() was trying to work around and not require the user to set LD_LIBRARY_PATH, but including all deps is ugly. I suppose having libapr in lib path is a 'decent' requirement and we should drop the workaround. Using the .a lib is imho the worst solution - and I'm not sure how it'll interact with the jni connector ( when apr syms will be loaded twice ). If there is only one *.so file that is no problem. Using a dynamic libapr was a lot of problems in mod_webapp. Costin On Mon, 14 Jan 2002, jean-frederic clere wrote: Hi, I am playing with jk2 and I have noted that the loadNative() in AprImpl fails: +++ java.lang.UnsatisfiedLinkError: /home/jakarta/jakarta-tomcat-4.0.1/webapps/jk/WEB-INF/jk2/jni/libapr.so: /home/jakarta/jakarta-tomcat-4.0.1/webapps/jk/WEB-INF/jk2/jni/libapr.so: undefined symbol: crypt at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1382) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1277) at java.lang.Runtime.load0(Runtime.java:698) at java.lang.System.load(System.java:797) at org.apache.jk.apr.AprImpl.loadNative(AprImpl.java:90) at org.apache.jk.apr.AprImpl.loadNative(AprImpl.java:78) at org.apache.jk.common.ChannelUn.init(ChannelUn.java:135) +++ The problem is that apr needs other dynamic library.
