JDB Access is denied
I need to debug a java service which is invoked by a c app(*.exe) on windows.
I use the
java -Xdebug -Djava.compiler=none -Xnoagent -Xrunjdwp:transport=dt_shmem,address=jdbconn,server=y,suspend=y -classpath D:/SOAM/3.0/samples/java/SampleApplication/bin MyService
to call my java service
then I use jdb -attach jdbconn
The result is
java.io.IOException: shmemBase_attach failed: Access is denied
