[aspectwerkz-user] Trying to hot deploy/undeploy aspects but get java.lang.UnsatisfiedLinkError: hotswap

Hi there,

 

I’m experimenting with hot deploy of aspects in AspectWerkz2.0 using
JDK1.4.2. I’m following the instructions from HYPERLINK
"http://aspectwerkz.codehaus.org/weaving.html#Native_HotSwap"http://aspectwe
rkz.codehaus.org/weaving.html#Native_HotSwap and I’m sure its picking up the
dll from the path because I have even put it in my jre/lib directory but I
get a java.lang.UnsatisfiedLinkError: hotswap which I understand is the
client trying to make a non-existent of misspecified JNI call. Can anyone
point me in the direction of what I’m doing wrong? I am using ant rather
than the batch file but the output from the ant java task looks the same as
the instructions. I feel its either some sort of JVM issue or to do with the
dll
