JNI and Tomcat

I am trying to use a JNI library on Tomcat. I have created a class with a JNI API. I have tested its use being calling it from a Java application. It works. When I try to invoke it from my app server (Tomcat), I get a java.lang.UnsatisfiedLinkError exception. I must find a way to specify where the library is located, but haven't found how to do this. I have tried to add a -Djava.library.path=... option in the JAVAOPT environment variable in the shell where I run the catalina.sh script, but this didn't help.
Any advice?

If you are using tomcat over UNIX, you shold put the LD_LIBRARY_PATH pointing the path of your native library.

Problem with JNI and Tomcat (and threads???)

Howdy,
Here is the issue - I would like some help on HOW to debug and fix this problem:
2 test use cases -
1)
a)User goes to Login.jsp, enters user and password
b) User submits to LoginServlet
c) login calls JNI code that connects to a powerbuilder(Yes I know this is ugly) PBNI code module (this is a .dll) that authenticates the user with the database
d) the servlet then redirects to another .jsp page
e) user then submits to LogoutServlet - also a JNI call to a powerbuilder PBNI code module
f) REPEAT STEPS a-e over a few times (inconsistent) and then the call to the JNI code hangs
2)
a) users does NOT goto Login.jsp, but rather calls LoginServlet and passes the userid and password as GET parms
b) user does NOT get redirected to a page (redirect code commented out)
c) user calls LogoutServlet
d) repeat steps a-c at will and no failure, no hanging
The only difference is that in case 1 (with JSP), there is a redirect and it afffected the JNI call by haniging inside JNI code.
In case 2 (without JSP) there is still a JNI call, but it does not hang. In addition, when it hangs and I stop Tomcat, the logs show cleanup entries that say:
Oct 19, 2004 9:17:09 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Oct 19, 2004 9:17:10 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Oct 19, 2004 9:17:11 AM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Is this a threading issue in Tomcat???
On would assume that the JNI code is not cleaning up after itself, but I don't believe this is the case,
and even if it was, why would I get the tomcat log cleanup entries above???
What do those cleanup entries imply about the state of Tomcat????

hi ,
I met the same problem this morning, and searched the www.google.com in order to solve it, as a result, your article was shown on my screen. :)
Till now I have read some technical information and solved my problems. Maybe the solution be useful to you:
==============================
error message : (Environment : Tomcat 5, Windows 2003, Mysql5)
2006-3-29 11:53:48 org.apache.catalina.core.StandardWrapper unload
message: Waiting for 2 instance(s) to be deallocated
==============================
cause: the number of connection to database exceeded.another word,too many connections.
==============================
solution: close the connection when it becomes useless for your program. :)
==============================
ps. Sorry for my weak English . hehe ....

JNI and Tomcat running on Linux

Hi all!
I have a small problem with calling a native library from my Tomcat running on a linux.
The code is simple enough
System.loadLibrary(myLibrary);I know that when libmyLibrary.so isn't in the java.library.path I get an error at this line. When it is in the path it goes past this line with out problems but on the next line
myFunction(); that is a function within myLibrary i get something like
java.lang.UnsatisfiedLinkError: myFunction()The thing is. This exact code when either executed in a standalone java application or from a Tomcat running on windows works with out problem. Tomcat on linux doesn't.
myLibrary uses other libraries on a different path and my guess is that tomcat for some reason won't allow access to those. The security manager however doesn't give me any errors, nor does tomcat itself other than the UnsatisfiedLinkError.
Anyone running Tomcat on linux and using native libraries or perhaps just knows alot about this?
Please help. Thanks!

Are you sure you are not running into a class loader issue? Does this occur the very first LoadLibrary call or after the first successfull call?
It could be that your JNI or bridge has already been loaded by another class loader in the tomcat class loader hierarchy and this would result in the UnsatisfiedLinkError.

JVM Crash When Using JNI and COM

I'm trying to call a DLL compiled from VB6 source code that I do not have access to. The VB6 code simply retrieves data from a DB2 database using ADO and my client code grabs that data and marshals it to my Java code. I'm attempting to achieve this using JNI and COM (without a third-party bridge). It works 75% of the time, but the other 25% of the time, the JVM crashes with the usual Hotspot crash log containing an access violation exception. However, I don't know what in my C++ code (VC++ 8) could be causing this except for passing a "wild" pointer to the code lying underneath the COM object interface. If that is the case, I don't know how I am doing that.
The Java code that is calling my native method is running on Tomcat 5.5.25 and just to be safe, I am not allowing multiple threads to concurrently call the method in my JNI DLL (though I realize that this will kill performance). Once I can get past this problem, I'll do the COM interfacing on a worker thread in my native code so I don't screw up CoInitialize and CoUninitialize calls in the case the same thread is concurrently executing multiple calls to my native code.
I've noticed that in most cases, the JVM crashes during my call to the pClsAccount->OpenConnection method. However, my DLL isn't what is listed on the top of the call stack, which is why I suspect the passing of a wild pointer, though I'm just taking a guess at that. Does anyone have an idea as to what's going on ?

Communication problem between NetBeans and Tomcat

hi!
i got a quite mysterious problem. here is what happens:
- i start NetBeans 5.5.1 (the first time)
- i want to debug my JSF-Project, the Debugger starts
- After a few seconds the debugger waits for tomcat (it sais: "Waiting for Tomcat...") and tomcat starts
- Again after a few seconds the tomcat-debugger-output sais "Tomcat startet in 3333 ms".
okay.
when i enter http://localhost:8084/ in my browser i get the tomcat homepage, so the server has definitely started! But nothing happens in NetBeans and nothing happens with my project....
In the lower-right corner i see this blue working-bar that sais "deploying project" but nothing happens. The Project-Debugger-Output still sais "Waiting for Tomcat..." but nothing happens...
And after something around 3 minutes (i guess it's a timeout) i get the error "Starting of Tomcat failed." But is HAS started, i can login to the Administration-Area in my browser!
so i guess there is a communication problem between netbeans an tomcat. Netbeans waits for a message from tomcat but tomcat doesn't send it..or netbeans doesn't understand it.
But the story goes on:
When i press the debug-button a second time it takes only a few seconds till i get the message: "Tomcat server port 8084 already in use". OF COURSE! Because Tomcat has already startet and can't be stoped by NetBeans.
i'm trying to solve this problem for 4 days now, so i would be very happy if anyone has an idea where to start/continue the search...
thanks,
flo.

Problem launching a jsp page with eclipse and tomcat

Hi,
I have just started using eclipse and tomcat for creating dynamic web pages. I tried to launch a jsp page after starting the tomcat server with the URL: http://locahost:8080/HelloWorld/, an error page was displayed as below:
HTTP Status 404 -/
type Status report
message /_
description The requested resource (-) is not available
Apache Tomcat/5.5.17
I didn't get any error at the console and when i just typed http://localhost, a pop up menu saying that the connection was refused when attempting to contact localhost.
I'm not sure what is the problem here. Could it be the permssion to the localhost is not granted by the system as the eclipse IDE is running using linux?
Hope someone can help.
Thanks.

Why do I need to restart Apache and Tomcat every time a java file is change

If a java file is changed and complied the changes are not reflected if Tomcat is not restarted.
The settings in server.xml are as:

<Context path="/manager" docBase="manager" debug="0" privileged="true"/>
<Context path="/cf" docBase="cf" debug="0" reloadable="false"/>
Here "cf" is my Application folder under webapps. The reloadable property when set to "true" for standalone Tomcat on Windows98 reflects the changes for compiled java files without restarting Tomcat. But on Linux 7.1 with Apache 1.3.19 and Tomcat 4.0.3 this is not working.
Also tried out with Manager Application of tomcat-users.xml with reloadable="false" as well as reloadable="true",
But when I reload the application using the command
http://servername:8080/manager/reload?path=/appli.name
It tells me that the application is reloaded but changes in the java file are still not reflected.
Also when reloaded through Manager Servlet, Only my load-on-startup servlet is reloaded, but other java classes are not.
Is it neccessary to execute this reload command from the server itself. I m executing it from a remote m/c. and have mapped the application with a domain name virtually.
Is it the case with Tomcat on Linux with Apache. Or is something going wrong on my part.
Can someone Help out plz.
Regards,
Rupali

or you can "touch" your web.xml file.
touch web.xmlor that command is for *nix systems, not sure what the Windows command is. But basically, when you edit the web.xml, even if it means updating the last modified time, it will restart only your application and you should see the changes.

NetBeans 5.0 and Tomcat 4.1

Hello,
I'm using NetBeans 5.0 and I have been using the Bundled Tomcat version 5.5.9 for my servlet container and everything's been great. Now that I'm ready to push my application up to a web host, I found that my host (lunarpages) runs with Tomcat 4.1 which uses version 2.3 of the servlet container. Tomcat 5.5 uses servlet container 2.4.
So I downloaded Tomcat 4.1 (which has 2.3) and I don't know how to properly tell Netbeans to use it. When I open Server Manager and select 'Add Server', I can't just tell NetBeans to point to my Tomcat 4.1 directory. It wants me to select from a dropdown list of servers and Tomcat 4.1 isn't in the list.
I tried to fake NetBeans out by selecting the 'Tomcat 5' server and pointing to my Tomcat 4.1 directory but I'm getting the following message when I try to run:
FAIL - Unknown command /deploy
C:\workspace\myApp\nbproject\build-impl.xml:425: Deployment error:
Can anyone point me in the right direction on how to get Tomcat 4.1 running with NetBeans 5.0?
Thanks,
Eric

I found that my host (lunarpages) runs with Tomcat 4.1 which uses version 2.3 of the servlet containerPlease read the post before answering, the reasoning is crystal clear.
I don't have a concrete answer to this problem, but I do have a suggestion.
1) You can add your own tomcat server to netbeans. Under the runtime tab you will find servers, if you right click this you can add a server. Use this to manually configure your own server
2) as for the servlet spec problem, when creating a web project setting the java EE version to 1.3 might solve the problem... I can't tell this for sure because I've never done it.

Java 1.5 JNI and C++ exception

Hello, All
I've troubles with handling C++ exceptions using JNI and shared library. I'm using Java 1.5_06, RedHat 7.3 and JBoss 4.0.5
From Java class I call JNI a method in my shared library(libx.so) which calls a method in other shared library(liby.so). Liby.so uses Xerces library. During parsing process an exception occurs. But according to Xerces sources it's a normal behavior and should be caught. But instead I've got SIGNABRT in JVM and a core dump will created. What's wrong? Backtrace shows similar something:
XXXXX __default_terminate() ....
XXXXX __terminate() ....
XXXXX __throws
XXXXX C++ method ..
XXXXX.....
XXXXX.....
XXXXX JNI methodI found similar bugs reports in the forum. But they says about Java 1.4 version and according to bugs descriptions it should be already fixed.

The question is closed. The root cause was incorrect building of shared library.

Preinstalled apache, apache2 and tomcat

Hello,
I'm setting up a Sun Fire V490 running solaris 10 for use as a web server. I need to have Apache httpd version 2 and tomcat version 4.x to run.
So I found that the machine comes with apache httpd 2 preinstalled and also apache httpd 1 with fully integrated tomcat engine.
But as stated I need to have apache httpd 2 with tomcat running!
Apart from configuring the system to run httpd version 2 instead of version 1 by use of svcadm, I'm wondering how to get a solid solution to also have tomcat running. Ok I could simply install a tomcat version from apache.org, but I would like to ensure that this is the right solution for e.g. future upgrades.
So if anybody has got some more knowledge but this issue, I would be happy about letting me know!
Thanks, Raimund

Hey, I came into the same question while configuring tomact on Sun server.
So, what did you finally do...........?
any help will be great....
Thanks,

Setting up eclipse and tomcat

Does anyone here have any expertise configuring these two products?(eclipse and tomcat)
I have my tomcat server running and it process them jsp pages just fine. I have also installed the plugin to get tomcat configured with eclispe.
I am just having problems running a jsp file directly from tomcat. it always points to a file on the hd and not to the webapps area like it's supposed to......

Sure - we use that combo for development all the time.
What's the problem specifically? Did you create a new Tomcat project in Eclipse? If you did, then it will automatically add the project's web path as a context to Tomcat, and you can browse directly to it using your browser.
FYI - note that the context that is created is going to point to the eclipse workspace directory - NOT the default webapps directory that you might have configured for Tomcat. That's OK.
