0000915: Socket JNI library is not available
We have compiled Resin pro 3.0.17 with the following parameters:

./configure --prefix=/usr/local/resin-pro-3.0.17 --enable-jni --disable-ssl --enable-linux-smp --with-java-home=/usr/local/j2sdk1.4.2_08

The installation goes through without errors and it seems to find JNI without problems.

Part of configuration output:
checking for JNI in /usr/local/j2sdk1.4.2_08/include/linux ... found

Part of make output:
make[2]: Entering directory `/home/teemupo/resin-pro-3.0.17/modules/c/src/resin_os'

/usr/bin/ld -shared -fPIC -o jni_os.o jni_jvmti.o jni_jvmdi.o -lpthread

But we still get the following complain into stdout.log when starting the server:

Here are some details about the environment:

I am new to Linux/ Resin. How did you do:
./configure --prefix=/usr/local/resin-pro-3.0.17 --enable-jni --disable-ssl --enable-linux-smp --with-java-home=/usr/local/j2sdk1.4.2_08

Could you explain little more on that.

I have similar problems on Solaris 10 on AMD64. I turned the debug level up to "finest" and it looks like a problem with shared libraries -- I get " wrong ELF class: ELFCLASS64" if I run Resin using the standard start script, or " internal: message buffer overflow" if I tell the start script to run the JVM in 64-bit mode.
