How to set java.library.path form code

I'm new to JNI. I see there are several ways to set JVM to look for libraries dll, so, etc.
     System.setProperty("java.library.path", ".");
     System.loadLibrary("hello");That's when UnsatisfiedLinkError
java.lang.UnsatisfiedLinkError: no hello in java.library.path
     at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
     at java.lang.Runtime.loadLibrary0(Runtime.java:822)
     at java.lang.System.loadLibrary(System.java:992)
     at HelloWorld.main(HelloWorld.java:17)But if I comment the line that sets the java.library.path and call the program with the command java -Djava.library.path=. HelloWorld works.
The question is: Why is not working? How should it be the property setup? I rather don't set Variables, or use -D option.
Thanks in advance.
PD: If it helps I'm using JDK 1.5.0_01 on Linux kernel 2.6.8

well i wrote the script and everything is fine! i can run the blackbox example on the commapi.
But i am writing another program using netbeans to send some data to a PIC microcontroller using the serial port (that is why i installed the commapi), and when i'm trying to build it or run it on netbeans throws this error:
Error loading LinuxSerialParallel: java.lang.UnsatisfiedLinkError: no LinuxSerialParallel in java.library.path
Exception in thread "main" java.lang.UnsatisfiedLinkError: isDevLink
at com.sun.comm.Unix.isDevLink(Native Method)
at com.sun.comm.PathBundle.add(PathBundle.java:108)
at com.sun.comm.PlatformPortBundle.<init>(PlatformPortBundle.java:44)
at javax.comm.CommPortIdentifier.<clinit>(CommPortIdentifier.java:138)
as far as i know it seems to be missing a library (LinuxSerialParallel), if this is right, adding the library would solve the error?how can i add the library? is there another way to solve this?
thanks in advance!!

Setting java.library.path property in java code

Hi,
i'd like to set java.library.path property in java code to load a dll-library. I know that a funtional way is to run JVM with parameter -Djava.library.path=c:\tmp, but I need it do it IN CODE.
I'v tried this:
System.setProperty("java.library.path", "c:\\tmp");
System.loadLibrary("libapr");The library 'libapr.dll' is situated really in 'c:\tmp' directory, but I get 'java.lang.UnsatisfiedLinkError: no libapr in java.library.path' exception.
It seems like the already running java program doesn't use actual java.library.path set in previous step.
Is there any possibility to set java.library.path property in java code?
Thanx
Brny

I think the following code should work:
// Reset the "sys_paths" field of the ClassLoader to null.
          Class clazz = ClassLoader.class;
          Field field = clazz.getDeclaredField("sys_paths");
          boolean accessible = field.isAccessible();
          if (!accessible)
               field.setAccessible(true);
          Object original = field.get(clazz);
          // Reset it to null so that whenever "System.loadLibrary" is called, it will be reconstructed with the changed value.
          field.set(clazz, null);
          try {
               // Change the value and load the library.
               System.setProperty("java.library.path", "c:\\tmp");
               System.loadLibrary("libapr");
          finally {
               //Revert back the changes.
               field.set(clazz, original);
               field.setAccessible(accessible);
The idea is to make the static field "sys_paths" null so that it would construct the paths from the changed value.

Still got java.lang.UnsatisfiedLinkError even after I set java.library.path

Hi,
I developed a Java application which uses JNI. Before I run the application, I set an environment variable JAVA_LIBRARY_PATH to where I put the .dll file required by my application. But when I try to run the application, I always get the exception of "java.lang.UnsatisfiedLinkError " saying that no the required .dll in java.library.path. Could anyone please tell me what's going on there ?(I am using JDK1.5.0_05.)
thanks !

Hi Scott,
Thanks for your help !
I also tried setting PATH before. But with this setting I got another problem that if I tried to the application the second time or more times, it always gives me an exception saying that the dll library already loaded by another loader. That's why I moved to set JAVA_LIBRARY_PATH because this way ever worked for me when I used lower version of Java. I did not use -Djava.library.path= option because I want to invoke my application from web application which may use RMI or HTTP.

How to pass java.library.path as a VM argument in JNLP file

I jave a jar file containing reference to sqljdbc4.jar as I am using JDBC to talk with SQL Server. It works fine through eclipse IDE when I give the fillowing VM Argument

Thanks for the pointer. Question that I have is I am referencing sqljdbc4.jar in my application, which in turn using sqljdbc_auth.dll.
Which one should i refernce through <nativelib>. Is it sqljdbc4.jar or sqljdbc_auth.dll.
have added the following line to the .jnlp.
<nativelib href="sqljdbc4.jar"/>
But still it is complaining on sqljdbc_audth.dll. If it is sqljdbc_auth.dll, can I use <nativelib> to pass it.
In that case does it need to be signed?. If so,
Is it possible to sign .dll using 'jarsigner'?.

Error with System.loadLibrary(...) with java.library.path set

I'm trying to get my feet wet with JavaMonkeyEngine using netbeans (on Windows XP SP3, Java 1.6).
When I try to run a simple example program, I'm getting
Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl.dll in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1709)
My runtime arguments include: -Djava.library.path="../../../../../projectSupport/jME2/lib/lib/lwjgl/native/windows/:etc
I'm pretty sure that the path is correct, because I tried the following code:
String [] dirs = System.getProperties().getProperty("java.library.path").split(":");
for(int i = 0; i < dirs.length; i++ ){
String path = dirs[i] + java.io.File.separatorChar + "lwjgl.dll";
if( (new java.io.File(path)).exists()) {
System.out.println("found in dir " + dirs);
path = (new java.io.File(path)).getAbsolutePath();
System.load(path);
System.out.println("was able to load library manually");
and the System.load method was reached and didn't throw an exception.
However, the below call does throw an exception.
System.loadLibrary("lwjgl.dll");
Presumably, I shouldn't need to put the dlls into my Path (otherwise whats the purpose of the -D argument).
I would appreciate some brilliant illuminating thought about now, something like "you forgot the magical snafu parameter" or such.
Thanks in advance.
Eric.

My runtime arguments include:
-Djava.library.path="../../../../../projectSupport/jME2/lib/lib/lwjgl/native/windows/:{code}So, you're on a Windows OS, and looking for a Windows DLL?
I'm pretty sure that the path is correct, because I tried the following code:
{code}String [] dirs = System.getProperties().getProperty("java.library.path").split(":");{code}So, you're specifying a path using the UNIX separator ':', instead of the Windows one ';'?
Your test code has the knowledge to parse a LINUX-like path, but the Windows VM doesn't have this knowledge (I admit the misleading part is that the VM generally accepts '/' as a file separator (instead of the Windows-standard '\' one), but doesn't recognize the ':' separator). Try using ';' to separate multiple pathes in your command line:
{code}-Djava.library.path="../../../../../projectSupport/jME2/lib/lib/lwjgl/native/windows/;<noticeTheSeparators>;... J.

UnsatisfiedLinkError and java.library.path?

I did look for this topic in this forum. The question has been asked, but I don't see an answer :(
I get an error at runtime...
"java.lang.UnsatisfiedLinkError: no EZTaxJavaCpp.dll in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)"
Code...
public class EZTaxJNI {
private native void sendEZCmd(String cmd);
static{
System.loadLibrary("EZTaxJavaCpp.dll");
public static void main(String[] args) {
EZTaxJNI ez = new EZTaxJNI();
ez.sendEZCmd("control initialize");
System.out.println("JNI");
The dll exists. I tried adding the path with the dll name and it didn't work. I tried removing the .dll extention and no luck. Where do I set java.library.path?

regarding the dll not found :
- if you state System.loadLibrary(...) you need to put the dll into a system library (like system32)
- if you state System.load(....) you can/must specify the complete path to your dll
regarding the UnsatisfiedLinkError :
three reasons I can think of :
- if your java module belongs to a package, i.e. if you have a statement like
package com.hllapi;
in your code, then you need to state this in the native code like this
JNIEXPORT jstring JNICALL Java_com_hllapi_JRmmApi_runCommand (JNIEnv *env, jobject obj, jstring cmd)
- something in the header file is wrong ?
I usually have the 'extern "C" .....' statement in the header file,
but I guess your way should work as well
- finally, I just realized, that you have two underscores in your statement after 'Java'
-> Java__EZTaxJNI_sendEZCmd(JNIEnv* env, jobject, jstring jMsg
this might be a problem
Hope this helps....

How the java.library.path is set?

Hi,
Can anyone please tell me know how System class (or JVM) sets the default value of the property java.library.path?
I tried searching the answer on net but I was not able to find any thing.
Regards,
Kev.

If you don't set it, I believe the JVM then reverts to using the search strategy of the native system.
On Windows, that means first looking in load directory, then looking in the Windows directory. (I made this intentionally vague; I believe these actually changed at one point during Windows' history.)
It is something else on Unices.

How can i find what the java.library.path is?? urgent

Hi,
I have an unsatisfiedlinkerror and the message is no jicmp in java.library.path. can anyone tell me how to do System.out.println and the path???
This is very urgent so anyhelp would be gratefully recieved
Thanks
Vanessa

I have an unsatisfiedlinkerror and the message is no
jicmp in java.library.path.
can anyone tell me how to
do System.out.println and the path???System.getProperty() will retrieve the Java-defined system properties. You can use the following code to determine the available values:
public static void main( String [] args ) {
java.util.Properties p = System.getProperties();
java.util.Enumeration keys = p.keys();
while( keys.hasMoreElements() ) {
System.out.println( keys.nextElement() );

How to add path to "java.library.path" property?

I use this command to set the "java.library.path" property:
java -Djava.library.path=./libs HelloWorldBut it will overwrite the default value. How can I add the path "./libs" to the default value of "java.library.path"?

Have you tried
-Djava.library.path=%PATH%;./libs The command search path is the only default I know. By the way, are you certain that the present working directory will always be the parent of "libs"?

LoadLibrary doesn't use java.library.path set at runtime

I'm trying to set the property java.library.path at runtime so I don't have to drop my .dll in the regular system path for a System.loadLibrary to work. This is the sequence I use in a static initilizer:
System.setProperty("java.library.path", "C:\\");
System.loadLibrary("DialButton");
When I put the file DialButton.dll in C:\ I get an java.lang.UnsatisfiedLinkError, but when I put it in D:\WINNT it works fine. I would expect it to do the opposite because presumably I blew away the real java.library.path when I ran setProperty and it shouldn't know to check D:\WINNT.
I'm trying to keep my application install clean and use a directory structure that maintains all of the required files without cluttering system directories. I also want to dynamically load JNI libraries for a distributed application after copying them to the local machine.
Thanks in advance,
Ryan

In the bug parade I've heard excuses from Sun programmers that this is a read-only property and isn't supposed to be changed. It probably took them longer to write the reply to the bug than it would have to fix the code.
I looked at the source code for the ClassLoader and for the source release of the JDK 1.3.1 and here's the code I found in the ClassLoader.loadLibrary() method:
        if (sys_paths == null) {
                usr_paths = initializePath("java.library.path");
                sys_paths = initializePath("sun.boot.library.path");
        }It seems it parses and caches the system and user library paths on startup and then never bothers to check them to see if they've changed ever again. I think it would be pretty simple to rewrite that code block by moving one line of code down two lines as this:
        if (sys_paths == null) {
                sys_paths = initializePath("sun.boot.library.path");
        usr_paths = initializePath("java.library.path");I mean, it's not as if loadLibrary is really performance intensive or even critical enough to bother caching at all!
This one code change could fix a lot of headaches.
The particular headache I'm working on is that there doesn't seem to be any support in the Servlet 2.2 or 2.3 specification for JNI files. I'd really love to be able to use a directory like WEB-INF\jni to store libraries that need to be distributed with my web application. I tried to dynamically change java.library.path to include WEB-INF\jni, but alas I ran into the same problem you did, it doesn't work.
Is is possible for this to be fixed, ever? I think it would take longer to say no and make up a reason why not then it would to actually make the fix... seems a good enough arguement to do it to me.
And alternately, can we come up with a standard place to put JNI stuff for web applications in the next Servlet standards?
Thanks in advance!

Does JVM variable java.library.path make sense from native code?

Hello all,
Well, everybody loads native library from the Java side by calling System.loadLibrary("myNative").
But what if, for example, myNative.dll loads another two libraries itself?
Suppose, when I call java method "initMyNative", it in turn call native function Java_initMyNative(...). That Java_initMyNative(...) wants to load two native libraries and make: HINSTANCE lib01 = LoadLibrary("auxlib01.dll"); // LoadLibrary from capital, it's Win function!
HINSTANCE lib02 = LoadLibrary("auxlib02.dll"); // LoadLibrary from capital, it's Win function!As specified, native LoadLibrary call will look for auxlib01.dll and auxlib02.dll in catalogs which are enumerated in system variable PATH, current catalog.
Does java.library.path make any sense on order of such search?
If not, is there any way of flexible configuring of the catalog in which to look auxlib01.dll and auxlib02.dll for?
I see some ways:
* changing system variable PATH - not flexible
* passing content of java.library.path into native code, parsing it and looking for auxlib01.dll and auxlib02.dll in each catalog listed in java.library.path - too heavy
I hope there is more smart way to do that.
Thanks, Alex

Thank you Shane for your reply. I actually didnt have to create 2 jar files, one for Java files and one for the dll file. I got an idea from your post and referenced the same jar file twice by saying:
<j2se version="1.2+" />
<jar href="HelloWorld.jar"/>
<nativelib href="HelloWorld.jar"></nativelib>
and by saying that the jnlp file started working from the browser.
Again, thanks a lot for your replies.
Thanks

ERROR on AIX - no library weblogicoci36 (libweblogicoci36.a or .so) in java.library.path

I have WLS 5.1 SP10 running successfully on all platforms (Solaris,

We have "worked around" this problem. We switched to the Oracle thin

Technical Support on this issue. I'll post updates as we get more

I haven't tried 5.1 on AIX, but I know in 6.0 there is an error in startWebLogic.sh
specific to AIX: it exports "LIB_PATH" when it should say "LIBPATH". I just checked
in the 5.1 script and it appears to have the same error. You need to change the
name "LIB_PATH" to "LIBPATH". This error is fixed in 6.1 so we can be sure there
is at least one other person on the planet who is trying to use Weblogic on AIX.
:-)Tom,
Thanks for the help. Unfortunately, I cannot find a reference to
LIB_PATH in setEnv.sh or startWebLogic.sh. At this point, we are
pursuing the possibility that the IBM JDK 1.2.2 introduced some
incompatibilities. From the "IBM AIX Developer Kit, Java TM2
Technology Edition, Version 1.2.2 README":
"Because of incompatibility between the IBM AIX Developer Kit, Java
TM2 Technology Edition, Version 1.2.2"..."JNI executable programs,
including third-party software packages and those built for previous
Java software releases on AIX, that were built without this binder
option are NOT compatible with the JVM in this
release"..."Compatibility of an executable program can be verified
using dump -ov The stdout output will show the modtype to be "UR"..."A
script file (convertJNI) is shipped in the directory
/usr/java_dev2/sdk/sh. This script will help you to convert the
modtype to UR in the optional header of your JNI executable programs
without having to recompile the code."
Out of the hundreds of potential files, which need to be converted?
Based on additional information obtained by running in verbose mode,
we were able to gather the following:
java.sql.SQLException: System.loadLibrary threw
java.lang.UnsatisfiedLinkError

No jacob in java.library.path.doc

I am running Developer Suite 10g on Windows XP. I have the OC4J instance running. I am using WebUtil and trying to use the OLE2 stuff. When I execute the code, nothing happens (see errors below) except all my buttons go dead. I checked, and it does not seem that I am getting the Jacob, JNIsharedstubs, and the d2kwut60 DLLs to download to my Jinitiator directory. I removed and reinstalled Jinitiator, but still nothing. If I manually copy the DLLs to the directory, I at least begin to get OLE2 errors. I read the message board (and modified Word.Basic to Word.Application) and read the WebUtil manual and reviewed my set-up. Any suggestions are much appreciated.

I'm not sure about 10G, but for 9ids this is definitely wrong (see famous page 6 of 49 WebUtil Manual). On 9ids you have to add the virtual directory in orion-web.xml only, not in forms90.conf. On 9ias it is vice verca.
Hope this helps

Oracle Calendar - UnsatisfiedLinkError: no csdkjni in java.library.path

Hi, all.
I deployed my test calendar application developed using Jdeveloper 10.1.3.0 (on Windows XP) to the Oracle 10.1.3. AS on a linux server, but the CalendarServer in on another installation (Collaboration Suite 10.1.2) on the same linux server.
When I try to executed the code that calls the calendar server I get this error:
500 Internal Server Error
javax.faces.el.EvaluationException: java.lang.UnsatisfiedLinkError: no csdkjni in java.library.path
I set the LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/ocal/lib on the collaboration suite 10.1.2 installation.
When I try to run the code on my Jdeveloper I get the same error:
java.lang.UnsatisfiedLinkError: no csdkjni in java.library.path
In my windows machine I create a folder where I put the dll's and jar files that came from the collaboration suite windows installation, but I get always the same error
This is the code:
try
Api.init("calendar.ini", "calendar.log");
catch(Api.StatusException e)
System.out.println("init returned status'" + e.getMessage() + "'");
System.exit (1);
Is my approach correct? Because if i'm developing on Windows and I need dll's files to connect to the calendar server on linux, but when I deploy the application to the linux server those dll's are useless and cannot be used. So am I missing something here? Do I need anything else to get this to work?
Best Regards,
Rui

1. Use 1 and only 1 of classes12.zip and ojbc14.jar; they have different versions of the same classes in them.
2. The Oracle OCI driver for JDBC uses .dll files or .so files from the Oracle client installation (as well as Oracle network configuration files, I think); most people use the thin driver instead to avoid this problem.
To use the thin driver, change your url, see here for details:
http://www.oracle.com/technology/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm#05_00
To stay with the OCI driver (not recommended), you need to have the appropriate Oracle client installation (or at least get the dlls or sos), and I think set additional environment variables, such as ORACLE_HOME and possibly LD_LIBRARY_PATH. I don't do this myself, so I can't give much more advice.
