hi Dave, thx for your response!
i build again xalan-c and xerces-c from sources generating libxalanc.so and
libxercesc.so, copied into /usr/lib and linked in my c project, and it
worked! well, almost! ;)
this is implementation code:
This is not a Java development newsgroup, so this is not the appropriate
forum for questions about JNI. I suggest you get your code working outside
of the JNI environment first, then attempt to integrate it.
JNIEXPORT void JNICALL

(JNIEnv *env, jobject obj, jstring xml, jstring xsl) {
XALAN_USING_STD(cout)
XALAN_USING_STD(endl)
cout<<"what the fuck!, joder, vamos avanzando!!!!!"<<endl;
jboolean blnIsCopy;
XALAN_USING_STD(cerr)
//XALAN_USING_STD(cout)
//XALAN_USING_STD(endl)
XALAN_USING_STD(istrstream)
XALAN_USING_STD(ofstream)
XALAN_USING_STD(ostrstream)
#if defined(XALAN_STRICT_ANSI_HEADERS)
using std::strlen;
#endif
XALAN_USING_XERCES(XMLPlatformUtils)
XALAN_USING_XALAN(XalanTransformer)
// Call the static initializer for Xerces.
XMLPlatformUtils::Initialize();
// Initialize Xalan.
XalanTransformer::initialize();
// Create a XalanTransformer.
XalanTransformer theXalanTransformer;
You need to make sure all Xalan-C and Xerces-C objects are destroyed before
you call XalanTransformer::terminate() and XMLPlatformUtils::Terminate().
In the case, you are creating a XalanTransformer instance on the stack,
which will not go out of scope until the end of the block. Since you
terminate Xalan-C and Xerces-C _before_ the end of the block, your
application will likely crash.
The easiest way to work around this is to add an extra scope:
// Initialize Xalan.
XalanTransformer::initialize();
{
// Create a XalanTransformer.
XalanTransformer theXalanTransformer;
...
}
XalanTransformer::terminate();
XMLPlatformUtils::Terminate();
const char* const theInputXmlDocument
=env->GetStringUTFChars(xml,&blnIsCopy);
//printf("datos en bruto\n: %s\n",theInputXmlDocument);
const char* const theInputXslDocument =
env->GetStringUTFChars(xsl,&blnIsCopy);
//printf("plantilla xsl\n: %s\n",theInputXslDocument);
// Our input streams...
istrstream theXMLStream(theInputXmlDocument,
strlen(theInputXmlDocument));
istrstream theXSLStream(theInputXslDocument,
strlen(theInputXslDocument));
XALAN_USING_XALAN(XalanDOMString)
XALAN_USING_XALAN(XSLTInputSource)
XSLTInputSource inputSource(&theXSLStream);
inputSource.setSystemId(XalanDOMString("foo").c_str());
// Do the transform.
int theResult = theXalanTransformer.transform(&theXMLStream,
inputSource, cout);
if(theResult != 0)
{
cerr << "StreamTransform Error: \n" <<
theXalanTransformer.getLastError()
<< endl
<< endl;
}
// Terminate Xalan...
XalanTransformer::terminate();
if i put this two terminate sentences together, it will crash with jvm
panic!
if i put only one, everything ok! would you explain me whats happening?
// Terminate Xerces...
XMLPlatformUtils::Terminate();
// Clean up the ICU, if it's integrated...
//XalanTransformer::ICUCleanUp();
cout<<"hasta aqui bien, seguimos!!"<<endl;
