Help needed with JNI - java.lang.UnsatisfiedLinkError

Question

I need some help with JNI. I am running on Sun Solaris 7 using their CC compiler. I wrote a simple java program that calls a native method to get a pid. Everything work until I use cout or cerr. Can anyone help? Below is what I am working with.
Note: The application works. The problem is when the C++ code tries to display text output.
My error log is as follows:
java Pid
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/dew/test/libPid.so: ld.so.1: /usr/j2se/bin/../bin/sparc/native_threads/java: fatal: relocation error: file /home/dew/test/libPid.so: symbol __1cDstdEcerr_: referenced symbol not found

Pid.java
========
* Pid: Obtains the pid from the jvm.
class Pid {
static { System.loadLibrary("Pid"); }
public native int getPid();
public static void main(String args[])
System.out.println("Before construction of Pid");
Pid z = new Pid();
System.out.println(z.getPid());
z = null;
Pid.cpp
=========
* Native method that obtains and returns the processid.
#include "Pid.h"
#include "unistd.h"
#include <iostream.h>
JNIEXPORT jint JNICALL Java_Pid_getPid(JNIEnv *env, jobject obj) {
/* cout << "Getting pid\n"; */
cerr << "Getting pid\n";
/* printf("Getting pid\n"); */
return getpid();

I forgot to include my build information.
JAVA_HOME = /usr/j2se/
LD_LIBRARY_PATH = ./:/opt/readline/lib:/opt/termcap/lib:/usr/bxpro/xcessory/lib:/${JAVA_HOME}/lib:/usr/RogueWave/workspaces/SOLARIS7/SUNPRO50/0d/lib:/usr/RogueWave/workspaces/SOLARIS7/SUNPRO50/3d/lib:/usr/sybase/lib
javac Pid.java
javah Pid
CC -G -I${JAVA_HOME}/include -I${JAVA_HOME}/include/solaris Pid.cpp -o libPid.so
Thanks again,
