Perhaps I'm being too ambitious here, but I'm trying to pass a shared_ptr back to Java through an Exception like so.
I am able to catch the Exception in java, but when I try to access any methods in the ManagementProcessor object itself I get a SIGSEGV. If I use new ManagementProcessorPtr() to send in an empty one I get the correct behavior (I throw a different exception).
Any insights?
Thanks!

typedef boost::shared_ptr<ManagementProcessor> ManagementProcessorPtr;
%include "boost_shared_ptr.i"
%shared_ptr(ManagementProcessor);
%typemap(javabase) Exception "java.lang.RuntimeException";
%typemap(javabase) AuthenticationExceptionManagementProcessor "NS/Exception";
%exception {
try {
$action
}
catch (AuthenticationException<ManagementProcessor> & e ) {
jclass eclass = jenv->FindClass("NS/AuthenticationExceptionManagementProcessor");
if ( eclass ) {
jobject excep = 0;
jmethodID jid;
jstring message = jenv->NewStringUTF(e.getMessage().c_str());
jstring file = jenv->NewStringUTF(e.getFileName().c_str());
ManagementProcessorPtr* realm = new ManagementProcessorPtr(e.getRealm());
jlong jrealm;
*(ManagementProcessorPtr **)&jrealm = realm;
jid = jenv->GetMethodID(eclass, "<init>",
"("
"LNS/ManagementProcessor;"
"J"
"Ljava/lang/String;"
"Ljava/lang/String;"
"J)V");
if (jid) {
excep = jenv->NewObject(eclass, jid,
jrealm,
e.getApiErrNum(),
message,
file,
e.getLineNum());
if (excep) {
jenv->Throw((__jthrowable*) excep);
}
}
}
Client code:
} catch (AuthenticationExceptionManagementProcessor e) {
java.lang.System.err.println(e);
ManagementProcessor mp = e.getRealm();
java.lang.System.err.println("got mp");
java.lang.System.out.println(mp.getUUID());
}
And of course the right answer is that first I have to create the Java ManagementProcessor object with the ctor that takes a CPtr:
jclass mpclass = jenv->FindClass("NS/ManagementProcessor");
jobject jmp = 0;
jmethodID mpid;
ManagementProcessorPtr *realm = new ManagementProcessorPtr(e.getRealm());
jlong jrealm;
*(ManagementProcessorPtr **)&jrealm = realm;
mpid = jenv->GetMethodID(mpclass, "<init>", "(JZ)V");
jmp = jenv->NewObject(mpclass, mpid, jrealm, true);
...
excep = jenv->NewObject(eclass, jid,
jmp,
e.getApiErrNum(),
message,
file,
e.getLineNum());
