Solaris native calls to packing libraries

Hello,
I do not know if this is the correct forum, and if not please redirect me. I'm researching the use of Solaris *,9,10 packaging via Java 1.4.2 by way of C/C++ and came across pkginfo.c from this url:
http://cvs.opensolaris.org/source/xref/on/usr/src/lib/libadm/common/pkginfo.c
and it suggests that libadm is where the functions are that I can use in my code.
Maybe I'm not looking in the right space/area. I wanted access to all the native library calls for all aspects of packing including the pkginfo, pkgadd, pkgrm, etc.
I didn't see one for pkgrm but found the pkginfo.c code, so I figured it's somewhere.
Any url that might help me figure this out would be appreciated. A book would be good, but not as fast.
A code snippet or idea would be great...
looking for a reference or a...
comon! it's aint going to work that way, you can only do it this way...
would help!
regards,
robert

Hello all who've viewed this page!
So in my copius spare time I found that libprodreg.so.1 contains the code that is available to do packaging and interfaces directly with the Sun's product database and now need to locate the specs on interfacing to it.
So if someone could give me a heads up that would be great.
Thanks in advance!

Forms 2.1 calling shared object libraries

Can Forms 2.1 on Solaris 2.6 make calls to shared object
libraries? What are the limitations / issues?
I have a large legacy COBOL program which I would like to
restructure and capture the business rule implementations into
shared object libraries. I would then like to implement a new UI
(character or GUI) for part of the system in Forms. I would
consider using forms built in features for getting data from the
database but all inserts updates and deletes will go through the
business rule layer implemented in COBOL and deployed as shared
object libraries on unix.
Any and all help is appreciated.

I have used Foreign Function Interface call (FFI) in Forms 5.0
to call function in Dynamic Linking Library (DLL) on Windows/NT.
You may be able to do the same thing (use FFI) to call shared
object libraries on Solaris.

Native Call (Java Call C program)

Hi all,
I am facing problem on compile the .so file for native call.
In step by step tutorial, after I compile as :
cc -G -I/opt/java1.3/include -I/opt/java1.3/include/hp-ux \HelloWorldImp.c -o libhello.so
Fllowing error occur :
/usr/ccs/bin/ld: Unsatisfied symbols:
main (code)
I am using HP-UX, any hints ?

I solved the problem.
Compile method in HP is not equal to Solaris.
and thus throw that error if I follow the step by step tutorial in Sun's page.
Details refer to :
http://www.hp.com/products1/unix/java/infolibrary/prog_guide/java1_3/JNI_java2.html

Stop native call from java

I know there are topics related to timeout, stop or kill native call but it seems there is no good answer for me.
I have a java class as the caller to call a native C function with double arrays as input. The C function perform some kind of computation using 3rd party FORTRAN functions. If we terminate the java, how to terminate/stop/or exit the C function?
Here is the partial of java class
public class PolyFit {
    public native double[] polyFit(int[]iParams, double[] dParams,
                                    double[] xx, double[] yy, int col);
    static {
        try {
            System.loadLibrary("polylib");
        } catch (UnsatisfiedLinkError e) {
            System.out.println ("Failed to load polylib");
            e.printStackTrace();
    public PolyFit() {
}The parent java class is a sub class of Thread that calls the PolyFit when running as a thread:
    int col2 = 2;
    for() { //more than 1000 pairs of inputX and inputY
        //iParams, dParams, inputX, inputY are assigned before
         PolyFit polyFit = new PolyFit();
        double[]output = polyFit .polyFit(iParams, dParams, inputX, inputY, col2);
    }Here is native C function (partial)
#include "PolyFit.h"
JNIEXPORT jdoubleArray JNICALL Java_org_ciit_stat_PolyFit_polyFit
            (JNIEnv *env, jobject obj, jintArray ja, jdoubleArray jda,
            jdoubleArray jdinX, jdoubleArray jdinY, jint col) {
    jdouble *output;
    jdoubleArray dbArray = (*env)->NewDoubleArray(env, MAX);
    (*env)->SetDoubleArrayRegion(env, dbArray, MIN, MAX, output);
   free(output);
    return dbArray;
}Every call of polyFit .polyFit() may take less than 1 millisecond to several second. In case the time exceeds a threadhold, i.e. 10 second, we want to stop the thread. However, I can't find the way to stop or exit the C function.
Any ideas are highly appreciated.

This is C code, and since there is no portable way to interrupt C code, there's nothing that can be done. In Unix a SIGINT can do the trick, but only by killing the whole address space. There are some thread APIs that attempt to do this, but they are either very unsafe or require cooperation from the code which is being interrupted.
Your best bet is to code your CPU-intensive code to check a global (or thread-specific) flag for a requested interrupt, and cleanly exit back to the JNI wrapper, returning a flag value to acknowledge the interruption. A wrapper routine around the native method can then throw a Java exception, or block and retry, or whatever you want it to do.
Note that Thread.stop is deprecated. There is no earthly way to cleanly interrupt either Java or C code, unless it cooperates with the interrupter.

Native call with J2ME

I can write native calls in C and use them in my J2ME applications. But if the application shall be integrated to a J2ME device, like a mobilephone, can the native calls then work on this device? This means the DLL (the native function) must be placed on the mobilephone.
Thx /Denker

Even more interesting, how whould you deploy your native bits (e.g. some sort of library) when you cannot even be sure whether your target does support a file system? Apart from that, I doubt you will get a programming API for your mobile phone (well, Symbian OS (e.g. Nokia 7650) provides one I think).

BE6000 Native Call Queuing Design Constraints?

We see the doc wiki has not been updated with any UCM 9.0 native call queuing design constraints. We would assume that the call queuing at a min would need to meet the MoH design constraint of 50 sessions, since you figure there is a high probability that one call will be queued in each of 50 queues with MoH playing with each.
http://docwiki.cisco.com/wiki/Supported_System_Capacities
Is there any other performance impact we should consider or can we ask the doc wiki be updated with design constraints around call queuing?
Can the BU clarify is that is 50 simultanous MoH streams per cluster, or 50 per server? We can eliminate the load by going to multicast and IOS distributed MoH for remote sites, but something tells me there probably is a max queued call ceiling we need to consider for this platform.

At the risk of getting caught up in the pass-by-reference/pass-by-value debate :), simple values (ints chars etc). are passed as values, and modifying them on the C++ side of the procedure call will not modify the values on th java side.
Possible solutions are:
1)pass an array of (say) ints. Then, modifying individual values should modify the java-side values (much in the way that the Stream.read(byte[]) functions do.
2)format up a strin g with your return values, return the string and parse it on the java side.
3)have fields in the java side that are accessed and modified by your native call.
4)pass an object with some fields in it. Have the C++ access and modify the object's fields.
Hope this helps.

How to maintain reference across native calls?

I'm using JNI to interface with an underlying C++ communications library. I am having trouble keeping my connection valid across native calls.
For example, in one method I connect and save the connection in a global variable, then return. After I connect I would like to call a "send message" method, but when I do I doesn't recognize the saved connection.
My question is do saved references persist across JNI calls when using the same object, or will all global vars be new ones? If not, does anyone know a way to get around this?
Thanks for your help

All JNI references that you create (through calls to NewObject, GetObjectArrayElement, GetObjectField, ...) or that are passed to your native code as parameters are local. That means that they are only valid for the duration of that native call and only on the thread from which that native call was invoked.
You can create global references from local references using NewGlobalRef. A global reference is valid across all threads and does not have a limited lifetime. You must make sure to release your global references once you are done using them by calling DeleteGlobalRef.

Web services server side uses C dll (native calls)

Hi,
I developed a web service using JAX-RPC. My implementation class uses native c function calls. Dose anybody know where I should put my C dlls and their dependentcy files on Web service server side (tomcat)? If they should be in the .war file, what kind of path in the war would be?
I have an exception ocurred, like this
[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault (StreamingSender.java:357)
[java] at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:228)
I think probably it is because of native call problem, since I could get something back if not using native call.
Anybody has similar experience when developing web service using JAX-RPC and calling native c api functions on server side?
Thanx in advance!

Yes, I just tried it again (comment all native call out and just call the method that doesn't use native call, it works).
So your web service application using jax-rpc and c native dlls works already?
Can you tell me where you put all the native C DLLs and where I can set java.library.path in tomcat?
Thank you!

CUCM 9.1 native call queuing - calls stuck in queue

Hello everyone
We are using the CUCM 9.1 native call queuing feature for attendants hunt group an have the following problem - if all the attendants are busy, the next arriving call gets into queue, receiving MOH treatment, as described in documentation. But if one or more attendants gets free and ready to receive calls, queued call doesn't get transfered to his/her phone. Logging in additional attendants, logging them in and out again doesn't change anything, once the call got in queue it stays in queue.
Exact cucm release version is 9.1.1.20000-5.
Has anyone seen this? Any ideas on what traces/logs to check?

Client (Solaris) remote call hangs 225sec if Server (Window7) is down.

We are noticing the RMI Client remote call from Solaris machine hang of exactly 225 seconds if RMI Server on Windows7 machine is shutdown. RMI Server is shutdown for valid reasons. The expectation is, Client would throw a RemoteException immediately for futher processing. The Client hang for 225 minutes is causing performance issues. This has been consistently reproduced across multiple machines with Client on Solaris and Server on Windows 7. There are no 225 sec wait issues if server is on Windows XP or Solaris.
Usecase (java version "1.6.0_14")
1. Start RMI Server on Windows 7 machine
2. Start RMI Client on Solaris machine
3. Wait till client connects to the server and makes some remote call every 1sec.
4. Shutdown RMI Server.
5. Client waits 225 seconds before a time out error is thrown.
Has anyone seen this problem? Any solutions to get around this?

Gdb's trace of the cause of all of my problems:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 90124 (LWP 11810)]
0x4c85a89f in outb () from /home/jason/FWheel/libfilterwheel.so
This is what I get from the debugger. I'm using the function outb to write to the parallel port address 0x378, which I've used the function ioperm to permit read/write access to. The program works just fine if I call the "stepFilter" function (that calls outb) outside of the ActionListener's actionPerfomed method. Like if I'm probing for keboard input inside the constructor:
* @author Jason Thomas
* @version 1.0
* Test program for the Java interface to my C++ FilterWheel object.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class FilterWheelTest
static
     System.loadLibrary("filterwheel");
FilterWheelTest()
     BufferedReader myReader = new BufferedReader(new InputStreamReader(System.in));
     String inString;
     try
     while((inString = myReader.readLine()) != null)
          myWheel.goToFilter(Integer.parseInt(inString));
     myWheel._delete();
     catch(IOException e)
     e.printStackTrace();
     System.exit(-1);
public static void main(String args[])
     new FilterWheelTest();
The program above works fine, the one I posted previously does not. The only difference is that the one I first posted is inside of an ActionListener, and this one is not.

Thanks, I set the NativeIO to false..... And hope that it gets ported.......

Associating native calls with the calling object

I have a problem where calls into a native library need to retain data for subsequent method calls. Imagine the following two native methods (just imagine that the signature is write for JNI methods):
void initialise(int value)
// Stores the value somehow
void dosomething()
// Does something with the previously stored value
}If I was to store the value in a global variable, then it would be shared across all instance of the java class wouldnt it? So if object 1 called initialise, then object 2 called initialise, whichever of the objects then called dosomething, it would be based on the latest call to initialise.
How do I get around this sort of thing?
I currently work in C, though I would be quite happy to switch to C++ if necessary.
Mossop

I haven't used JNI_OnUnload, but may see why it isn't called. The doc says it runs in the finalizer for the classloader that loaded the library. Assuming this is the system (not custom) classloader, then its finalizer will never run because it gets gc'd only at shutdown, and finalizers don't run at shutdown by default. You could try calling Runtime.runFinalizersOnExit, but it's deprecated and sounds unsafe.
So my next idea would be to add a shutdown hook (Runtime.addShutdownHook) the first time one of your objects is constructed. The hook would call a native method to do the cleanup. Or since a shutdown hook is a Thread subclass, just make your overridden run() be the native cleanup function.
Of course this now requires keeping a native-side data structure to track the native objects, though I'd still vote for storing each native peer's pointer in a Java long field for fast dereference, and make this native data structure be a simple array or list (not map) for usage only by the cleanup logic.
Another idea is to clean up in a function called by the OS or C++ runtime when your library is unloaded, independent of Java. This could be DllMain (for Windows) or a C++ global object destructor.

Native calls problem

Hi everybody,
Following is my problem --
i am working in linux environment with CLDC 1.0.4 and MIDP 2.0, downloaded from the sun site.
earlier i was using only cldc(kvm). For adding native code, i used to rebuild kvm adding .c files containing native functions in the given makefiles. And that was working fine. but i need to use midp classes, which i am not able to use by giving
KVM_HOME> kvm -classpath ../../api/classes:. testClass
i am not able to use midp classes from testClass, even if i specify it in classpath...
So, in order to use midp classes, i decided to rebuilt midp.. in midp makefiles i added .java files and corresponding .c files in SRC.. it is built without errors, but the entry of the new native function is not done in ROMjavaUnix.c or in nativeFunctionTable.c So, when i call the native function from the midlet, it obviously gives native function not found error..
I will be higly thankful to u, if u can help me in the same. There might be a point which i am missing.
Thanks and Regards,
Retesh

Hi,
I think following shd help u...
Following changes have been done in the MIDP RI 2.0 -
The classes containing the native function declarations are added to the MIDP_HOME/src/share/classes/
The corresponding C source files containing the native function definitions are added to MIDP_HOME/src/share/native/
In MIDP_HOME/build/share/makefiles/Defs.gmk the name of the C source file is added to variable MIDP_DEF_SRC
In MIDP_HOME/build/share/makefiles/Defs.gmk while defining variable MIDP_DEF_SOURCE, the name of the package (in our case urPackage) containing the class which contains the native function declaration is added as
MIDP_DEF_SOURCE:=$(shell find \
$(MIDP_DIR)/src/share/classes/java \
$(MIDP_DIR)/src/share/classes/javax \
$(MIDP_DIR)/src/share/classes/urpackage \
$(MIDP_DIR)/src/share/classes/com/sun/mmedia \
$(MIDP_DIR)/src/share/classes/com/sun/midp \
-name '*.java' | egrep -v 'midp/ssl|$(MIDP_EXCLUDE_CLASSES)')
In Defs.gmk (i don't remember the exact path)
when creating classes.zip the urPackage is given as
$(ZIP) -qr ../$@ java javax com urPackage);

Retesh

Need guidance on using ddi_regs_map_setup solaris system call

Hi all,
Am a beginner in using Sun Solaris.
I am working on porting our source code from linux to solaris.
In Linux we are using inb/outb to read/write to keyboard data port(0x60) .
I know that there is an equivalent system call for inb/outb in solaris. But in man page(of sun os) it is mentioned that inb/ outb are obsolete. It was mentioned that we can use ddi_get8/ddi_put8 functions respectively.
ddi_get8 call requires ddi_acc_handle_t as a parameter which we can get it from ddi_regs_map_setup system call.
Syntax for this call is:
int ddi_regs_map_setup(dev_info_t *dip, uint_t rnumber,
caddr_t *addrp, offset_t offset, offset_t len,
ddi_device_acc_attr_t accattrp, ddi_acc_handle_t handlep);
Please let me know where does the 0x60 port number fits in the above system call and what does these parameters rnumber, offset, len corresponds to ?

Hi,
The Fault_PC 0x13575e8 tells you exactly where you
die. I assume you have used this in mdb on
the core file to find you are dying in the ddi_get8 call?
Are you checking return value of ddi_regs_map_setup?
Are you sure the register you are accessing is in register set 1?
Are there other places prior to the panic where
the ddi_get/ddi_put routines work correctly? A bus error
here generally means the location you are trying to access
does not exist on the device. (It could also be alignment,
but not with ddi_get8). The address
looks like 1fe.02001400, which looks like a possibly
valid address in I/O space.
I would print the value of wc->ioaddr to make sure
it is a valid virtual address.
Hi,
I'm in the middle of porting a device driver for a
PCI card from linux to solaris (it's wcfxo from
zaptel - part of asterisk).

See previous message(s) for detailsThe actual code which seems to cause the panic is:
#define inb(a) ddi_get8(wc->devhandle, a)
ints = inb(wc->ioaddr + WC_INTSTAT);where there initialisation includes:
static struct ddi_device_acc_attr dev_attr = {
DDI_DEVICE_ATTR_V0,
DDI_STRUCTURE_LE_ACC,
DDI_STRICTORDER_ACC
ddi_regs_map_setup(wc->dip, 1, &wc->ioaddr, 0, 255,
&dev_attr,
&dev_attr, &wc->devhandle);I've tested the same card in a linux x86 box, and it
works fine, so I'm happy it's not a hardware
problem.
Any suggestions on what might be causing this?
Thanks,
Simon
