AccessControlException when using jnlp allpermissions on Solaris 10

Hi all,
A user of our free webstartable product yEd:
http://www.yworks.com/products/yed
running Solaris 10 x86:
$ java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
reports the following problem when launching our program:
Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission com.sun.media.imageio.disableCodecLib read)
     at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)

It seems like ImageIO cannot be loaded on Solaris 10 because the SecurityManager prohibiting access to the System property "com.sun.media.imageio.disableCodecLib" although we have "allpermissions" declared in our jnl file:
http://www.yworks.com/products/yed/demo/yed.jnlp
Can anyone running Solaris 10 reproduce this behavior or does someone have a clue as to what is going wrong here. I don't want to believe it is a bug in Java Webstart on Solaris. After all using ImageIO shouldn't be that special.

Bug: Watson #2818669 - AbstractAmfInput uses System.getProperty in Constructor leading to AccessControlException when using in Applet
QA: Yes
Doc: No
Checkintests: Didn't run - the change was to wrap the System.getProperty in a try/catch that would have caused the SecurityException, so no real functionality change that could affect the check-in tests.

Accessing External Url using Http Utility | Error when using from Weblogic on Solaris

We are using Http Utility (http://jakarta.apache.org/commons/httpclient/) from
Apache for accessing external URL. A XML string is sent as POST parameter to the
URL and the response is also an XML string. The URL is accessed over HTTPS protocol.
I am setting the following parameters in the java class:
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
// set the property
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
The java class written to access the external URL using Http Utility works perfectly
fine when it is run from either the command line (of Windows or Solaris using
main() ) or from weblogic on windows. The same java class throws an exception
when run from Solaris instance of Weblogic

Problems with cursor and shortcuts when using JNLP services on MAC OS X

After invoking the JNLP services on a MAC I loose the ability to set the cursor and invoke keyboard shortcuts. On Windows this is not a problem, so I believe it is a bug and I have reported it to Apple. Meanwhile, I would appreciate if someone could help me with finding a work-around. To identify the problem run the following code with Java Web Start (i.e., you need to add the program to a jar and launch it using a JNLP script). You also need to include the javax.jnlp package.
Observe that the cursor changes to cross-hairs when entering the circle. After invoking the Open file menu item, the cursor does not change any longer. Shortcut key do not work either, but if you open the menu and close it again without selecting any of the menu items, the shortcuts are OK again.

Barbara, Thanks very much taking the time to respond to my posting. Your input and directions were just what I needed.I accessed the print settings in the pull down menu, setup the print options including the color profile for Elements and the Printer to sRGB, and printed my picture. This resolved all the invalid color problems I was having, but I did notice that there was a hint of magenta overall in the picture. I had read an article that said to use Canon Color Matching instead of Color Sync to prevent that but I couldn't make that change in the pull down menu. I tried in the Presets dialog box but that didn't appear to be possible. Should I make that change as well?
Also, in my travels through Elements 13 I notice under Edit->Color Settings that there were options for No Color Mgmt, Optimize for Screen, for Printing, or ability to chose one or the other (real time I assume). How do those options fit into this scenario?
Thanks again

Client does not connect with the webservice no more when using jnlp

Hello
I am experiencing an issue, apparently only when i am trying to use my application from java web start
I have a server/client application that works well when run.
When trying to start the client using a .jnlp file (server allready being turned on) i stumbled upon an exception:
org.apache.axis2.AxisFault: Error during encryption
any help will be greately appreciated
thank you

Appears to be an Apache product fault , not a Java problem. Try Apache w/s.

App crash when using JAVA callbacks from native threads in solaris

Hi all,
Sorry for putting the thread here. I did use the native methods forum, I wasnt lucky. I Hope more people would look into this forum, which brings me here.
I have a solaris application which crashes when I try to callback the JAVA methods and variables from the native code. The description of the problem is below
Written a native library, the library is multithreaded (i.e) I create a thread using pthread_create() in the native code which performs the operation of calling a JAVA method from the native code. The routine of calling the JAVA method works perfectly elsewhere outside the new thread.
There are two scenarios I've tested it in
1. I created a thread (say X) from the main thread (say Y) and made the y to wait until the X is complete using the pthread_join(). The JAVA callbacks works fine when called from Y but the app crashes if done from X.
2. Did not make the Y to wait until the X is complete, hoping that both will run paralelly and even the the App crashes.
And to be precise the Y is the thread where the native method is called from JAVA.
I have tested for any memory leaks or stack corruption by removing the JAVA callbacks and bulding a executable and using purify, the report doesnot hint any such occurances.
The linker options used for building the shared library is as follows
${GPP} ${INC} -G ${LIB} -mt -g -lCstd -lCrun -lpthread ${OBJS} -o <lib-name>
I wonder if we can create threads in the native code when using JAVA callbacks and even if we can whether it would be appropiate to use the callbacks with in the threads
Looking forward for any help.
Regards,
Vamsi

Guys... can't any one help me with this problem :(

Application crashes when using JNI with Jdk 1,2, 1.3 and 1.4

Hi!
I have this application that has a GUI written in Java and a file parser written in C. JNI is used to connect these parts together. The problem is that the application only works when I am using jdk 1.1.8 but not when using jdk1.2, jdk1.3 or jdk1.4. I am running the application on a Solaris 8 machine.
I have not written the application myself but I am going to be working with it from now on. But I have today little knowledge with JNI and I have tried different approaches to solve the problem. For example I have tried to used DDD together with GDB to find out what the problem is but with no luck. When I run the application using jdk1.4 I get the following error when the JVM crashes:
An unexpected exception has been detected in native code outside the VM.

From this information I think that the problem should be in the native method setDebug. But I have tried to set a breakpoint at the beginning of that function in the C part but with no luck. The application crashes before it reaches that position in the C file.
What could possibly go wrong between the setDebug function in the C part and the function call in the Java part?
When using GDB, GDB cannot figure out what is wrong it just returns a hex address, no function name.
I would really appreciate some help. I have tried everything that I can come up with!
Best regards
Lars

I have figured out that the application fails on its first call to the native methods.
So I have this Bitmap class that contains all the native calls and it is defined shortly as follow:
public class Bitmap {
static {
System.loadLibrary("BitmapImpl");
native void setDebug(int debuglevel, int statistics);
There are many more native methods defined in Bitmap, but I only show the setDebug method because that is the first one that is executed and also the one that immediately fails.
My setDebug C function is defined as follow in BitmapImpl.c
#include <time.h>
#include <stdio.h>
#include <limits.h>
#include <fcntl.h>
#include <jni.h>
#include <math.h>
#include <errno.h>
#include "Bitmap.h"
#include "data.h"
jint debug = 0;
jint statistics = 1;
JNIEXPORT void JNICALL Java_Bitmap_setDebug
(JNIEnv *jenv, jobject jo, jint d, jint s)
debug = d;
statistics = s;
My libBitmapImpl.so file is compiled using the following Makefile and using GNU gcc:
JAVAPATH=$(JAVAINCLUDEPATH)
LMACRO=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DSOLARIS
CSOURCE=BitmapImpl.c
all:
gcc -O3 -G $(LMACRO) -I$(JAVAPATH) -I$(JAVAPATH)/solaris \
$(CSOURCE) -o libBitmapImpl.so
It is still a total mystory why the application fails. I have tried it on a RedHat Linux machine and there it works fine. But not on Solaris. Only if I use the jdk1.1.8 but not a later one.
Would really appreiciate some help!
Best regards

How to blank laptop screen when using external monitor/

Hi there
I need some help with figuring out how to configure my xorg.conf for my Arch Linux 64 bit installation on a HP Pavilion dv 5000 laptop so that I can automatically blank my laptop screen when using an external monitor. I have Arch Linux installed along with Ubuntu Feisty. In Ubuntu my external monitor (Viewsonic 1912WB) was not detected at the time of installation but with the native 1280X800 resolution that is good for the laptop takes effect for the external monitor automatically when the external monitor is plugged in. The laptop monitor goes blank when the external monitor is plugged in.
In my Arch Linux installation I have not been able to configure a dual head configuration using the ATI Radeon drivers (fglrx). I have the native 1280X800 resolution set up for the laptop monitor and this resolution takes effect for the external monitor also. However the laptop monitor also continues to function when the external monitor is plugged in. I would like to blank the laptop monitor when using the external monitor.
I am attaching my Arch Linux xorg.conf and the Ubuntu xorg.conf below. Thanks for anyone who can help, I am having a lot of difficulty in figuring out how to set up xorg.conf among all the things that I have had to learn so far in Linux and I am a relative newcomer to the whole thing. I have tried to compare the two xorg.conf files and edit my Arch xorg.conf in accordance with the Ubuntu one but it did not work and I keep getting errors!
I am using XFCE as my Desktop environment.

Xrandr 1.2 provides means for this. But today the only supported configuration is xorg-server-1.3 + xf86-video-intel-2.0. So for Radeon you'll have to wait for drivers that support Randr 1.2.
On my laptop (Thinkpad x60s) that would be:
xrandr --output VGA --auto
xrandr --output LVDS --off

App crash when using JNI callbacks

Hi all,
I have a solaris application which crashes when I try to callback the JNI methods from the native code. The description of the problem is below
Written a native library, the library is multithreaded (i.e) I create a thread using pthread_create() in the native code which performs the operation of calling a JAVA method from the native code. The routine of calling the JAVA method works perfectly from elsewhere.
There are two scenarios I've tested it in
1. I created a thread (say X) from the main thread (say Y) and made the y to wait until the X is complete using the pthread_join(). The JAVA callbacks work fine when called from Y but the app crashes if done from X.
2. Did not make the Y to wait until the X is complete, hoping that both will run paralelly and even the the App crashes.
And to be precise the Y is the thread where the native method is called from JAVA.
I have tested for any memory leaks or stack corruption by removing the JAVA callbacks and bulding a executable and using purify, the report doesnot hint any such occurances.
The linker options used for building the shared library is as follows
${GPP} ${INC} -G ${LIB} -mt -g -lCstd -lCrun -lpthread ${OBJS} -o <lib-name>
I wonder if we can create threads in the native code when using JAVA callbacks and even if we can whether it would be appropiate to use the callbacks with in the threads
Looking forward for any help.
Regards,
Vamsi

Guys... can't any one help me with this problem :(

How do can I use Jumpstart to boot Solaris from Slave Drive

Hi all,
I have XP on Master Drive and I used Jumpstart to install Solaris on Slave Drive.
This is the profile:
install_type     initial_install
system_type     standalone
usedisk          c0d1
boot_device      c0d1 update
root_device     c0d1s0
fdisk           c0d1 solaris all
partitioning     explicit
filesys          c0d1s0 10000 /
filesys          c0d1s1 1111 swap
filesys          c0d1s7 free /export/home
cluster          SUNWCreq
Now, I specified that the boot_device is c0d1 but after the installation the boot device is c0d0 which is my Master Drive...
...when I use Windows Boot Manager to boot Solaris... it cannot find the boot files on the master drive so it runs the DCA...
... so under the DCA I have to tell Solaris that the boot files are in my Slave Drive then I save it.
...I don't want to make this change everytime
any ideas that would make this install hands free?

...don't know the answer to that but here is an alternative:
... use this as your finish script
... it changes the bootpath in bootenv.rc to point to the slave drive
#!/usr/bin/perl
open(INFILE,"/a/boot/solaris/bootenv.rc");
open(OUTFILE,">/a/boot/solaris/bootenv.rc_out");
while(<INFILE>) {
chomp;
#--cmdk@0,0 is the master drive
#--cmdk@1,0 is the slave drive
s/cmdk\@0\,0/cmdk\@1\,0/g;
print OUTFILE "$_\n";
#...replace bootenv.rc_out with bootenv.rc
...happy programming

Errors found when using tar and ACL's

Having difficulties with TAR and ACLs, and wondering if anyone had seen this before.
Here's the scenario: create a few directories and a few files. Tar it up and extract the files. Now assign some ACL's to them (some default for directories), tar it up, and extract the files. Permissions should remain the same. Under most circumstances they are.
Now repeat the procedure, but put a default directory ACL on the parent directory where the TAR is created. What happens is that the group permissions for anything un-tared gets trashed.
Here's a script to test it out.
Create a dummy user (I called mine foobar) -- required for setting ACL's. Run the script with the "-d" option at first. Things appear good. You can compare the permissions on the bottom for each file/directory.
Run the script with the "-s" option setting default ACL's on the parent.

TESTDIR=/export/home/christian

# Run the script once with normal permissions (no ACL's) in the test directory (where tar is located)
# --> ./test.sh -d
# look at the result (ls -l) of .../sub1dir, .../sub1dir_acl, and /sub1dir_orig
# They should be relatively the same:
# --> rwxrwxrwx permissions on directories
# --> rw-rw-rw- on files
# Now run the script but set the parent directory of the script (where the TAR's are located) to have default ACL's
# --> /opt/MMSsyscnf/sub2dir/test/test.sh -s
# Now look at the result (ls -l) of .../sub1dir, .../sub1dir_acl, and /sub1dir_orig
# They are COMPLETELY skewed. Both times we tried to untar the files, ACL's wound up

Any ideas?

UFSDUMP has some limitations, including being on a file system that is read-only. Yes, I could force it on a read-write FS, but I normally stay away from big sticker labels found in man pages when I encounter them. :-(
What I was originally after was a script that makes a backup of application configuration files before I modify them. Thus, I tar/zip the directory.
These config files/directores have ACL's attached to them to allow various roles to access them (group permissions are not fine-grain enough). However, when I ran through a couple of tests, I came across a scenario that overwrote the original permissions. Tested it on Solaris 10 and Solaris 9, and both fail.
So now (very late into the feature design) I'm VERY concerned about using ACL's on Solaris, and wonder what other side-effects there are that I'm not aware of. Can't seem to find a bug report on it, so I thought I'd ask around to see if it was just the behaviour of the TAR/ACL that I'm not quite getting, or if it really is a bug.

Use of strstr() in solaris 2.8

Hi,
I have tried to use the strstr() when developing driver driver in solaris 8 environment and compile using Forte C compiler but it can't work. My system will crash whenever I run my program. Anybody have any idea how to solve this problem.
Thanks.

Hi There,
All components for Solaris 8 were built using the WS 5.0 compiler and compiling a driver with a different compiler is not supported and not good software practice...
A Common Build Environment document which spells
out what compiler is used to build each component of the Solaris release. This is to make sure that the Release Team can, at any time, reproduce the exact
code for the entire release...
You are using Forte 6 compiler to biuld the kernel module.
I suggest you refer to the Solaris 8 Developer Collection and refer Writing Device Driver's
Compiling, Loading, Packaging, and Testing Drivers Module.
