Native library problem
I am trying to get a berkeley xml database working in java and i get an error when i try to run their sample programs. I am trying this in linux right now with problems. I got it to work in windows.
I used this command to set the native library path:
export LD_LIBRARY_PATH=/home/test/Desktop/dbxml-2.3.10/install/lib/
When i run the sample program i get this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/test/Desktop/dbxml-2.3.10/install/lib/libdb_java-4.5.so: /home/test/Desktop/dbxml-2.3.10/install/lib/libdb_java-4.5.so: cannot open shared object file: No such file or directory
Do you have that so file in that location?
If yes then do the correct permissions exist for the app to access it?
If yes then are there any third party shared libraries needed? If yes then where are they?

AMStoreConnection native library problems
hi
trying to access the identity server 5.1 using a java standalone client in a solairs environment. There are some problems with native libraries, which couldn't be found. So whats going wrong? Is there any list describing which libraries to add to the LD_LIBRARY_PATH? Which properties file have to be included in the classpath? Additional hints?

I just managed to solve the issue. The issue is twofold.
1. The user running the pdeploy should have access to /var/opt/<product directories>
2. The admin password for web server and app server should be the same. You can actually reset web server admin password from the web server console.
I had spend 3 days searching before i started analyzing the issue myself. Hope this helps you saving time :) -
Problem : Native Library already loaded in another classloader
I created a shared library HaspKeyAPI.dll by using JNI and add path to Java class library. I need to call native functions in my servletAction class to check some information in a key. Sometimes not always, I met �java.lang.UnsatisfiedLinkError: Native Library C:\eclipse\workspace\HaspKey\SharedLib\HaspKeyAPI.dll already loaded in another classloader� problem. I have to restart tomcat server then to restart my web app.
Does anyone know how to fix it?
Thank you in advance!

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. -
Native library loading problem
Hi Folks,
I currently downloaded, and compiled the bDB core using VS 2010 x64 (I run 64 bit win7, and JRE 64 bit). In Eclipse I'm trying to use the native library (setting up the path correctly), however the java is complaining that it cannot find dependencies.
I switched to JE, it works fine, but I'm not sure if JE is as performant as the core version. Anybody had the same problem?
thanks in advance
Edited by: user5493457 on Mar 22, 2011 3:35 AMHi,
Please review the building process of the Berkeley DB libraries, to ensure you have correctly built them. Review Building Berkeley DB for Windows, Building the Java API and Java configuration. If you want to build 64-bit libraries, make sure you select x64 as platform configuration in Visual Studio when building.
I assume you are getting a java.lang.UnsatisfiedLinkError exception at runtime. Just to make sure Eclipse correctly finds the native BDB libraries, in your Run Configuration for the project you're trying to run, under Environment, add a new variable, LD_LIBRARY_PATH with a value of something like D:\BerkeleyDB\db-5.1.25\build_windows\x64\Debug (substitute Debug with Release depending on how you built the libraries) -- this is the path to the location of the native BDB libs, libdb51d.dll and libdb_java51d.dll (or libdb51.dll and libdb_java51.dll), so you should change it as appropriate for your system.
Also, for that Run Configuration add a new variable, CLASSPATH with a value of something like D:\BerkeleyDB\db-5.1.25\build_windows\x64\Debug\db.jar;D:\BerkeleyDB\db-5.1.25\build_windows\x64\Debug\classes (this is the path to the Java API classes and the Java API jar file -- db.jar). Make sure that "Append environment to native environment" option is checked, in the Run Configurations screen.

Re: not able create connection to timesten
checking the Release Notes I can see 11.2.1.8.0 has been tested against Glassfish 3 but I
can't see any mention about Glassfish 2 in the v7 or v11 Release Notes (albeit only on a quick
search).

Problems with loading native library/missing methods:no ttJdbcCS in java.li
Iam facing one problem while connecting the timesten client to the server The SQL Exception which Iam getting is pasted below:-
Problems with loading native library/missing methods: no ttJdbcCS in java.library.path
I am working with MAC OS X 10.7.2 and my timesten client version is 11.2.1.0
I have also changed the Java Preferences from 64-bit to 32-bit but still whenever i tried to connect with the SQL Developer it gives me the above error.I just tried this out. My environment is OS X 10.7.4, Timesten (32-bit) client 11.2.1.9.0, SQL Developer 3.1.07, Oracle Java 1.7.0_04.
The key things you need to be sure to do (in a terminal window) are:
1. Be sure to . in the TimesTen environment script <tt_install_dir>/bin/ttenv.sh to set the full TT environment.
2. Change directory to SQLDeveloper.app/Contents/Resources/sqldeveloper
3. Run 'sh sqldeveloper.sh -J-d32'
and all should be fine.
Note that if you are using Java7 as I am then there is a step 1a. Change the CLASSPATH environment variable to specify ttjdbc6.jar not ttjdbc5.jar. For some reason running the app directly from Finder does not work even if you add -J-d32 into the sqldeveloper launch script. I'm still looking into that.

Problems with loading native library missing methods ttJdbc1122.dll
Problems with loading native library/missing methods: C:\TimesTen\tt1122_64\bin\ttJdbc1122.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform
Hi,
I have installed TimesTen 11.2.2 64-bit version on 64-bit windows 7.
I have TimesTen 7 64-bit as well installed on my machice
When trying to connect to TimesTen (Direct connection) using jdbc from eclipse, I get the following error "Problems with loading native library/missing methods: C:\TimesTen\tt1122_64\bin\ttJdbc1122.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform".
The JDK version is 1.6.25 - 64 bit version.
Please help me resolving this error.
Thanks in Advance,
BalamuruganAre you using SQL Developer?
There is or used to be a restriction of only being able to using 32 bit. A suggestion might be to try the 32 bit client. -

How to use a native library (.so) in EJB
Hi,
I know how to package a native library into a connector in iAS. But I don't quite know how to use it. Suppose I provide a wrapper java class for the native library, can I use the java class directly in my EJB (since the classloader of the RA is the parent of the EJB classloader) or I have to issue an outbound call?
Also, if I package the native library into a RA (standalone), iAS will automatically load it so in my wrapper java class, I don't have to call System.loadLibrary(...). Correct?
Thanks,
HaitaoThanks, Russ. My older Mac Pro is a 2,1 -- I think I only missed by a few months in buying one that would run Mavericks (64 bit EFI). I do intend to buy a "trashcan" Mac Pro but not just yet.
As for updating projects — that's my issue, I think. The Mac Pro and the laptop are networked so I can be working on my laptop and go to the Mac Pro and open the Final Cut Pro that is resident on that computer. What is odd is that it doesn't open any of the projects that normally open up with I start up FCP X on the Mac Pro.
I frequently work inside the house on my laptop running programs that are on my Mac Pro outside in my office — usually no problem at all with Adobe applications.
FCP X won't let me open a project by clicking on the project — it insists that I "Open projects from within FCP X" but they won't open that way. This what is odd — that it won't let me open projects even thought they are fully native to that version of FCP and are even on the same hard drive on the Mac Pro. -
Native library working in Eclipse but not in command line ...
I was working on a Nutch project combing CMeCab with the analyzer.
It uses:
System.load('CMeCab');
where the problem occured. I have the file libCMeCab.so in /usr/lib/ and it was working fine inside eclipse.
But when I complie with ant (by the way I'm not familiar with this great tool, but followed the easy tutorial), and then run everything inside terminal like normal Nutch project. Everything was fine until the index process which uses native library CMeCab to analyze.
The error was:
java.io.IOException: Job failed!
And in the hadoop.log in detail:
java.lang.UnsatisfiedLinkError: no CMeCab in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
at java.lang.Runtime.loadLibrary0(Runtime.java:823)
at java.lang.System.loadLibrary(System.java:1028)
I didn't have runtime -D option in Eclipse run configuration for library path, and didn't know what was the difference that's causing the trouble. I googled trying hard, but most of the MeCab documentations is in Japanese and merely had the problem I had.
Please help me.
Thanks in advance.Hello,
I was working on a Nutch project combing CMeCab with the analyzer.No idea what Nutch and CMeCab are (but apparently this latter has unkempt hair ;o).
I didn't have runtime -D option in Eclipse run configuration for library path, and didn't know what was the difference that's causing the trouble.I won't know either why it works in Eclipse, but have you tried adding -Djava.library.path=/usr/lib to the command line, to check how it works? If it works, would this be a problem to use this configuration?

Error ocurred during initialization of VM. Unable to load native library...
Hi,
I´m trying to install Oracle 9i on a PC with Suse 9.2.
when I put the first CD it comes with this error:
Initializing Java Virtual Machine from /tmp/OraInstall2006-05-04_11-13-11PM/jre/bin/java. Please wait...
Error occurred during initialization of VM
Unable to load native library: /tmp/OraInstall2006-05-04_11-13-11PM/jre/lib/i386/libjava.so: symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
I´ve seen that there was a similar issue in 2004 and I´ve trying to do what it says but it didn´t work this time.
Unable to load native library:
Could everyone help me to install Oracle??? I´ve been trying it for a few days and doesn´t work.
Regards,I had same problems long time ago. Ok, I try to remember.
First I read the recommandation. You need a special GLIBC-Library to support the JAVA 1.1.8 runtime environment.
Some of the Oracle9i tools are compiled with gcc 2.95 compiler.
You may need gcc_old for SLES9 for linking of those tools.
gcc_old-2.95.3-175.2.i586.rpm is included in SLES 9 SP2 CD1
For Suse you can obtain a package called orarun. You will get further support for installing, starting and stopping ORACLE. Please look at http://ftp.novell.com/partners/oracle/docs/9205_sles9_install.pdf.
Good luck. -
Native library NOT thread safe - how to use it via JNI?
Hello,
has anybody ever tried to use a native library from JNI, when the library is not thread safe?
The library (Windows DLL) was up to now used in an MFC App and thus was only used by one user - that meant one thread - at a time.
Now we would like to use the library like a "server": many Java clients connect the same time to the library via JNI. That would mean each client makes its calls to the library in its own thread. Because the library is not thread safe, this would cause problems.
Now we discussed to load the library several times - separately for each client (for each thread).
Is this possible at all? How can we do that?
And do you think we can solve the problem in this way?
Are there other ways to use the library, though it is not thread safe?
Any ideas welcome.
Thanks for any contributions to the discussion, Ina(1)
has anybody ever tried to use a native library from
JNI, when the library (Windows DLL) is not thread safe?
Now we want many Java clients.
That would mean each client makes its calls
to the library in its own thread. Because the library
is not thread safe, this would cause problems.Right. And therefore you have to encapsulate the DLL behind a properly synchronized interface class.
Now the details of how you have to do that depends: (a) does the DLL contain state information other than TLS? (b) do you know which methods are not thread-safe?
Depending on (a), (b) two extremes are both possible:
One extreme would be to get an instance of the interface to the DLL from a factory method you'll have to write, where the factory method will block until it can give you "the DLL". Every client thread would obtain "the DLL", then use it, then release it. That would make the whole thing a "client-driven" "dedicated" server. If a client forgets to release the DLL, everybody else is going to be locked out. :-(
The other extreme would be just to mirror the DLL methods, and mark the relevant ones as synchronized. That should be doable if (a) is false, and (b) is true.
(2)
Now we discussed to load the library several times -
separately for each client (for each thread).
Is this possible at all? How can we do that?
And do you think we can solve the problem in this
way?The DLL is going to be mapped into the process address space on first usage. More Java threads just means adding more references to the same DLL instance.
That would not result in thread-safe behavior. -
Library problem with Oracle 10
I am installing Oracle 10 on Linux (CentOS)
I'm in the process of installing Oracle on the screen of the wizard "Setup Wizard", while trying to install the tool Oracle Net Configuration Assistant, this is canceled, and to review the log that is the problem:
UnsatisfiedLinkError exception loading native library: njni10
Where should I install this library that I need, and if not too much trouble, from where I can get it?.
Thank you very much.Friend, please answer:
Answering your question, the system is CentOS 5.3, and 64 bit architecture.
Sorry I uploaded the last consultation, the problem was that I still need to download a package, in the preparation stage of the system.
The package was missing:
glibc-devel for i386.
When you install this package addresses the issue.
Leave a link where I found this solution:
http://www.brucalipto.org/linux/how-to-install-oracle-client-10g-on-red-hat-enterprise-linux-5-64bit
Thank you very much for your help friend.
Thanks to this forum can finally install Oracle 10 on CentOS 5.3 -

In Object Library corner you can see one small button,It look this
Click that->Menu will Open-> "Restore default object for All groups"
or
Click that->Menu will Open->Shared Library Location->C:\Documents and Settings\Application Data\Adobe\Designer\EN\Objects\WebDynproNative
