In this instance, NMI was only lightly used, but the uses were widely distributed. Post as a guest Name. You can still use the javah command with the jni option to generate native method function prototypes needed for JNI-style native methods. For more information, see: Not doing so can cause incorrect behavior.

JNI does not require header information or stub files. I’ve added output jnk see what exactly is being sent to the connect call and it looks like the call is getting everything it needs:.
This code incorrectly assumes fprintf will never modify errno: Ok, I removed the fprintf statements, but I still have the same result.

B is the function that creates the socket and connect it to the server. Note – A native method that violates this restriction can cause the VM to abort randomly.
Login to Your Account. You can jno use the javah command with the jni option to generate native method function prototypes needed for JNI-style native methods.
Java Native Interface (JNI) (Java 2 SDK for Solaris Developer’s Guide)
Email Required, but never shown. I’ve added output to see what exactly is being sent to the connect call and it looks like the call is getting everything it needs: If anyone has the similar problem before and knows the solution, please help me out here.
You could try allocating larger C stacks using the java -ss option. The failure is around socket connect at or soon after that. Has anyone seen this before?
Post as a guest Name. If not on the Java side, then I agree with Roedy, build a uni non-Java app and debug it from there.
Making the Transition From NMI to JNI
Sign up using Facebook. All forms of printf will fail if: You have likely overwritten the bounds of something. Errors For the conditions under which printffprintfand dprintf will fail and may fail, refer to fputc 3C or fputwc 3C.
I have a native library and a java app that uses JNI to access the native library, my java app works fine on Solaris 8 and earlier SUN solaris releases, however on Solaris 9 it failed native app also works fine. It never reaches the second fprintf statement. You can also just preprocess your code instead of compiling it all the way, just to see if there are some macros screwing things up.
Java Native Interface (JNI)
Try to extract the troublesome logic into a standalone program and debug it the traditional way. I’d look first for someone doing something dumb like redefining errno doing anything to a system’s jnl of the errno macro results in undefined behavior You cannot call other JNI operations. The solarid command generates C header and source files that are needed to implement native methods.
The result is placed in the. The printffprintfdprintfand asprintf functions may fail due to an underlying malloc 3C failure if: You cannot call back into Java while holding onto the array elements.
Coaching, problem solving, economical contract programming. Because of these restrictions, the array elements can be accessed without pinning and without copying. And per the Solaris For example, an engineer who was unfamiliar with the application ported lines of C code in approximately two days.
