Except that with the bridge, much of the work can be done in highly optimized C code (there's a separate driver for each platform), rather than in java, which probably makes up for the extra layer. In addtion, they say that ODBC is a native interface for SQLAnywhere, so there are fewer layers than most ODBC implementations would have.

Win7 calling native code via JNI
Hello,
I have a ROOT webapp running in Tomcat 6.0.20 as a SERVICE on
Windows 7 and it runs fine calling native code via JNI.
Now for debugging purposes :
I'm trying to run it with tomcat not running as a service (tomcat
started via startup.bat) and the load
of my bridge dll is ok, but as soon as I call the dll's init function
(CPPInit) it crashed the JVM.
If you look at the code you will see I try to create a file on the
root of the C drive (remotedebug.txt) and
this file never gets created but I don't think that is what is
causing the crash as CPPInit is called after
this file create and CPPInit seems to be what's failing.
See Code and JVM crash below.
Native Code Header:
/*

I want to have failover for session as supported by JvmRouteBinderValve. Is this possible to set up in an environment where multicast is not supported? Do I need to set up a Cluster though I don't need session replication since I'm using persistent manager for session storage so all tomcat instances have access to session data? What I want is just the JvmRouteBinderValve behavior of changing the session id to the new jvmRoute and setting cookie when a tomcat instance receives a session request from a different jvmRoute.

Re: Win7 calling native code via JNI
There is only a 32 bit JVM on the machine. The bridge dll has not been recompiled since mid '08. If it was an incompatibility with the Microsoft Runtime Library wouldn't you expect the Service Version to do the same ? If you look at the code you will see I try to create a file on the root of the C drive (remotedebug.txt) and The file does get created via the Service but not standalone, weird. If it was crashing as a result of the file creation, would you expect to see the CPPinit at the top of the stack trace ?
