PHP 4.0 as a servlet: How is the C++ runtime initialized across a JNI call?

I am building PHP 4.0 for use as a servlet under Tomcat. When I attempt to run date.php via Tomcat, I get a segfault the first time I attempt to call 'new' to instantiate a C++ object. At first I thought the problem was caused by the specific class (istdiostream). Then I created a simple class as follows: class simple_class { private: int i; public: simple_class(int in) { i = in; } } Get a segfault when I attempt to create an instance of this class as well, so the problem is not with the class, but somewhere in the runtime. I suspect the problem is that the C++ runtime is not being initialized. JNI is a C interface AFAIK so that implies the PHP code needs to do it. Looking for a string to pull so I can unravel this problem. Thanks, Bill
