Executing native library under Java - shell script problem

I am running a Java application on the command line bash shell. I have a few JAR files in the directory and a few native libraries. When I run the application using the command line, all works fine. This is the command I use:
java -classpath MyGame.jar:log4j-1.2.16.jar:jme/jme-colladabinding.jar:jme-audio.jar:jme-awt.jar:jme-collada.jar:jme-editors.jar:jme-effects.jar:jme-font.jar:jme-gamestates.jar:jme-model.jar:jme-ogrexml.jar:jme-scene.jar:jme-swt.jar:jme-terrain.jar:jme.jar:jogl/gluegen-rt.jar:jogl/jogl.jar:jorbis/jorbis-0.0.17.jar:junit/junit-4.1.jar:lwjgl/jinput.jar:lwjgl/lwjgl.jar:lwjgl/lwjgl_util.jar:lwjgl/lwjgl_util_applet.jar:swt/windows/swt.jar:jbullet/jbullet-jme.jar:jbullet/asm-all-3.1.jar:jbullet/jbullet.jar:jbullet/stack-alloc.jar:jbullet/vecmath.jar:trove-2.1.0.jar:sceneMonitor/jmejtree_jme2.jar:sceneMonitor/propertytable.jar:sceneMonitor/scenemonitor_jme2.jar:sceneMonitor/sm_properties_jme2.jar -Djava.library.path="lwjgl/native/linux" -Xmx1024m -Xms768m -ea com.mygame.MainThis works fine and the application starts up as expected. LWJGL native library is loaded in and works fine as expected.
The problem occurs when I try to run this command via the shell using a shell script. Here is my script:
#!/bin/bash
# Set the minimum and maximum heap sizes
MINIMUM_HEAP_SIZE=768m
MAXIMUM_HEAP_SIZE=1024m

Thanks for the replies guys/gals.
I have modified the script and echoed my command that should be running under the shell script, it is:
java -classpath WcgFramework.jar:WcgPocSwordplay.jar:log4j-1.2.16.jar:jme/jme-colladabinding.jar:jme-audio.jar:jme-awt.jar:jme-collada.jar:jme-editors.jar:jme-effects.jar:jme-font.jar:jme-gamestates.jar:jme-model.jar:jme-ogrexml.jar:jme-scene.jar:jme-swt.jar:jme-terrain.jar:jme.jar:jogl/gluegen-rt.jar:jogl/jogl.jar:jorbis/jorbis-0.0.17.jar:junit/junit-4.1.jar:lwjgl/jinput.jar:lwjgl/lwjgl.jar:lwjgl/lwjgl_util.jar:lwjgl/lwjgl_util_applet.jar:swt/windows/swt.jar:jbullet/jbullet-jme.jar:jbullet/asm-all-3.1.jar:jbullet/jbullet.jar:jbullet/stack-alloc.jar:jbullet/vecmath.jar:trove-2.1.0.jar:sceneMonitor/jmejtree_jme2.jar:sceneMonitor/propertytable.jar:sceneMonitor/scenemonitor_jme2.jar:sceneMonitor/sm_properties_jme2.jar -Djava.library.path="lwjgl/native/linux" -Xmx1024m -Xms768m -ea com.mygame.MainI am more confident that now the shell script should be fine (I am a shell script noob) because this very command if I copy from terminal and paste into the terminal, runs the application no problem at all.

I used the code as suggested:

Problem with loading native library in java version "1.5.0_05"

My application uses a native coded drawing. With java version 1.4.xx it was working just fine but with java 1.5.xx it gives the following error at the time of loading native library:
java.lang.UnsatisfiedLinkError: /home/abyzov/tmp/friend32-1.6.02/libfriend.so:
/home/abyzov/tmp/friend32-1.6.02/libfriend.so: undefined symbol: XtWindowToWidget
I assumed that java loads all necessary X-libraries at start up but it seems to be not true for version 1.5.xx. Does anybody now about this kind of problems? Should I report it as a bug?

I have this exact same problem. I developed an application all along using 1.4.2_08 to be exact no problems. I was forced to switch to 1.5.0_06, now when I try to run the app I get:
java.lang.UnsatisfiedLinkError: <path to library>/libcomlib.so: <path to library>/libcomlib.so: undefined symbol: yp_get_default_domain
I have tried compiling it in both 1.4.2_8 and 1.5.0_06 and it compiles perfectly but when I run with 1.5.0_06 it messes up.
If you found the problem with this or anyone else has any advice please let me know.

Do shell script problem in Applescript

Hi,
I am an Applescript novice and have been trying to write a code to go to a particular folder, look for all files in the folder tree with extension .m2v and run an executable file to decode them. My problem is that when I run my code (containing do shell script), it searches through all files and folders on Mac HD and starts decoding .m2v files elsewhere that I don't want.
Eventually it runs out of space (.m2v file decoding takes a lot of space), because it is dumping all decoded .yuv files onto the HD.
When I run the command on Terminal, it executes the decoding perfectly and stores the decoded files in the same folder.
Please help me about what's going on.
My code is something like:
tell application "Finder"
set DestinationFolder to "xxxxxx:xxxx:xxxx"
set NumFolders to (get count of folders under Destination folder)
repeat for SomeVar from 1 to NumFolders
set FolderinQuestion to folder SomeVar of DestinationFolder
-- Tried tell application "Terminal" here, but did not know --how to export the FolderinQuestion variable from Finder to --Terminal
do shell script " \" cd \" & (POSIX path of (result as text));
for file in `find $pwd \"*.mov\"`
do
/usr/local/bin/decode file
done"
end repeat
end tell
I would greatly appreciate some guidance.

The root of the problem is that you're trying to quote the cd command for some reason:
<pre class=command>do shell script " \" cd \" & (POSIX path of (result as text));
...</pre>
In addition to that you're including the & (POSIX path of (result as text)) as part of the shell command whereas this should be OUTSIDE of the quotes in order to get evaluated
If you work that through you'll end up with a shell command that looks like:
<pre class=command>" cd " & (POSIX path of (result as text))</pre>
If you try to run that in a terminal you'll get a cd : command not found error and that's why the rest of it appears to fail.
The solution to that one is simple - just don't bother quoting the cd and put the POSIX path stuff outside of the quotes to get it evaluated at runtime:
<pre class=command>do shell script "cd " & quoted form of POSIX path of (FolderInQuestion as text)) & ";
# rest of shell commands here"</pre>
Now, as for the rest of the script there are a few things I would change.
First, unless you need to know the index, don't do:
>repeat for SomeVar from 1 to NumFolders
set FolderinQuestion to folder SomeVar of DestinationFolder
the issue is that the number of folders to process may change during the script's execution (other processes may create or remove folders). This will, at best, cause some folders to be skipped and, at worst, cause the script to fail.
If you're iterating through a list, the best option is to just:
<pre class=command>repeat with FolderInQuestion in (folders of DestinationFolder)
...</pre>
This automatically sets the iterator (in this case, FolderInQuestion, to the first item in the list and increments it for each iteration through the loop.
Secondly, in your shell script itself, scrub the entire do/done loop. You're already using find, so have that do the hard work using the -exec switch:
<pre class=command>find path -name "*.mov" -exec /usr/local/bin/decode {} \;</pre>
In find's case, {} is substituted with the current file's path.
Putting this together you'd get:
<pre class=command>tell application "Finder"
set DestinationFolder to "xxxxxx:xxxx:xxxx"
repeat with folderInQuestion in (get folders of folder DestinationFolder)
do shell script "cd " & quoted form of POSIX path of folderInQuestion & "; find . -name \"*.mov\" -exec /usr/bin/decode {} \\;"
end repeat
end tell</pre>
Note that I've used 'quoted form of POSIX path' - this takes care of any shell-unsafe characters like spaces in the path name. I've also used \\; for the -exec switch - this is so that AppleScript passes the \ to the shell command rather than using it for its own escaping.
But you're not done yet!
There's still one fatal flaw in this process - and that is the fact that find by default, is recursive - it will walk through every directory that it finds.
This means that if you start at the top folder and iterate through, find will find all .mov files and decode them. Your script then cd's to the first subdirectory and repeats the process - decoding all the .mov files in that directory and all its subdirectories even though they've ALREADY been decoded.
The upshot is that you only need to run one loop starting at the top level. You don't need to iterate through all the subdirectories since find will do that for you.
In addition to that, there might not be a need to use cd at all since the first argument to find is the directory to start searching in. Unless there's some reason that you need to start decode from the top level directory (e.g. is that where it saves the files?), you can drop the whole repeat loop altogether and just run with:
<pre class=command>set startFolder to (choose folder)
do shell script "find " & quoted form of posix path of startFolder & " -name \"*.mov\" -exec /usr/bin/decode {} \\;"</pre>
That's the entire script - a radical compression of your original.

Rel 12 - How to create a new APPS connection from custom Java/Shell Script

Hi,
I am looking to write a custom JAVA code / Shell Script which needs to establish a connection to execute a PL/SQL API on Rel 12 db.
The challenge is to be able to connect without specifying APPS Password anywhere (just like Oracle Apps does it).
This Shell script / Java code is not called from within Apps hence I need to establish a brand new connection along the lines of using ....
WebAppsContext ctx = new WebAppsContext(System.getProperty("JTFDBCFILE"));
OracleConnection conn = (OracleConnection)ctx.getJDBCConnection();
like in 11i world or possibly using APPLSYSPUB username
I need help / direction in how to do this in a Rel 12 env. I understnad there are lot of architecture changes and if someone can provide a generic code snipped it will be great.
I need to keep this as closely aligned to Rel 12 coding and security standards as possible.
This code will reside in $XXCUSTOM_TOP/bin file or under XXCUSTOM.oracle.apps.java....... if its Java.
Pls help.
Cheers
-- VK.

Hi,
Have you looked at Oracle produced dbc file and its contents? That might help. It is under $FND_TOP/secure. It uses GWYUID=APPLSYSPUB/PUB. I am hoping that the APPS_JDBC_URL would help too.

Run java shell script on Linux

Hi I am just trying to convert a Windows batch file to a unix shell script to run a java application, but it so long since Ive used UNIX I cant really remember how to do it.
My script contains
#!/bin/sh
java -jar lib/testapp.jarThese are my failed attempts to run it, not too sure what the differences are but I think the 3rd one is the only one to actually find my shell script.
[root@]# testapp.sh
-bash: testapp.sh: command not found
[root@]# ./ testapp.sh
: bad interpreter: No such file or directory
[root@]# . testapp.sh
Unable to access jarfile lib/testapp.jarif I just do this at the command line it works fine
[root@]#java -jar lib/testapp.jar

#1
[root@]# testapp.sh
-bash: testapp.sh: command not found
#2
[root@]# ./ testapp.sh
: bad interpreter: No such file or directory
#3
[root@]# . testapp.sh
Unable to access jarfile lib/testapp.jar#1 is because the command (testapp.sh) is not found on the PATH. Under Unix the current directory . is not included automatically in the PATH: it has to be excplicitly specified, and this is a good thing. Also make sure it has the x (executable) switch on: chmod +x testapp.sh
#2 is because you had an extra space in what should have been
./testapp.sh #3 there you could "inline" the script but the file lib/testapp.jar was appearently not found. Is lib really under the working directory or in other some place?

Executing crystal reports through a shell script

We are currently in the processing of building a POC using Crystal reports and was hoping to find a way to execute canned crystal reports via a shell script. The reason being we wanted to schedule the executing of the report through our scheduler where we would build in the dependencies.
Does anyone have a simple example on how to do that.

What sort of shell script? Can you provide more info?

Specify native library in java command line

My application is :
1. packed into 1 jar file
2. use sqljdbc4.jar
2. use a native library: "Microsoft SQL Server JDBC Driver 3.0".(use it in Ecplise and it works fine)
3. run by this command: "java -jar myapp.jar".
java version is jdk1.6.0_23
btw: I config all the class paths in the manifest.mf file
My application is failed to run, since it cannot find the native library. How/where to specify the native library location?

Simple shell script problem...

I am trying to get a list of directories on a remote machine, compare them with the directories on the local machine and copy any that dont match on the local machine to a backup folder. Heres my code but i am a newbie and i cant get my shell script to read from a file. The for loop never executes so i am guessing i am not reading the file correctly - see below.
#!/bin/ksh
ssh -l removeserver 192.168.xxx.xxx ls /remote/server/directory/ > /store/remote/directory/listing/motapp1files.txt
newfile=''
$newfile < /store/remote/directory/listing/motapp1files.txt
for file in $newfile;
do echo $file
if [ ! -d local/machine/directories/$file/ ]; then
echo "this folder doesnt exist on on remote server "; echo $file;
fi
done

Re-inventing the wheel perhaps. Look into rsync. Great program!

Sqlldr ops$user/password in a shell script - problem

Hello All:
i run the sqlldr command from a unix shell script that has
sqlldr ops$user/password@alias control='/path1/control.ctl' log='/path2/log.log'
I am geeting invalid user/password because of the $ sign in the username. What is the workaround for this? How to handle this in the script?
I tried single quote, USERID= unsuccessfully. Any ideas?
Thanks

Hello,
Single quote should work fine , can you post your shell script specially couple of line and try connecting from command line.

It is stucked because RMAN it waiting input on STDIN and you don't give anything as input to STDIN.
Try to use

Calling a native library from Java

Hello,
I'm trying to call a native method (windows dll) from a web service implemented in Java. I've confirmed that the class I've created to call the native method works when used outside of my web service (ie. in a standard Java application). However, when I try to use the class in the web service, an exception is thrown when
System.loadLibrary("MyLibrary");
is executed. The exception thrown is:
InvocationTargetException
JAXRPCSERVLET28: Missing port information
Does any one have any suggestions as to what might be causing this error?
Thanks

There are basically 3 steps to calling a native method from your Java code.
1. Create a C/C++ stub function that will translate between your Java call and the native C method.
2. Create the dll that exports the stub function.
3. Invoke the System.loadLibrary("myDllName") method.
Here's what I did to learn how to use the JNI.
I first created the class that would be calling the dll:
public class CallDll
/** Creates a new instance of CallDll */
public CallDll()
static
//LVtoJava is my dll name.
System.loadLibrary("LVtoJava");
//AddDll is the name of the function I'm exporting from my Dll
//It does not have to be static
public native static double AddDll(int func, double x, double y);
I then used the javah utility in the jdk/bin directory to create the C stub header file. Once you have the generated stub header file, you can create an implementation file, and compile it into a dll.
//My C++ stub, generated by javah utility
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class LabViewDll_CallDll */

You may want to note the stub function's signature and how it decorates the function name that you created from your Java class. Do not modify it, as the format is required by the JNI. The javah utility appends the fully qualified package name and the word Java, separated by underscores, to your original function name. You do not need to change the name in your Java class.
All the other special key words in the function's signature are defined in the jni.h or the jni_md.h (if your using windows).
You may want to refer to the JNI documention on Sun's website. The book I learned out of is the Core Java Volume 2, published by Sun Microsystems Press. It goes through the details of invoking your first native function and I've found it to be a good reference.
Hope this helps,
PS. I seemed to have found the issue with calling my dll from a web service. My dll is actually calling another dll and that seems to be the source of my problems. When I removed the call to the 2nd dll, everything worked fine. So now I need to figure out why the 2nd dll call is an issue.
Any suggestions?
