You can't use JNI like that. You have to use the 'javah' header-fine
generator and then write your native code to that specification. For a
class called JNITest and a method called doSomething that takes no
arguments, the method signature needs to be:
JNIEXPORT void JNICALL Java_JNITest_doSomething
(JNIEnv *, jclass);
You might want to read-up on using JNI: it's not as simple at the IJW
stuff C# provides.

Sounds like a Java-class/native-library mismatch. Are you sure your
.java file and .c files are sync'd up properly? Try recompiling
everything, and double-check your JNI method signatures.
What does modelJNI.initModel look like in the Java method declaration?
What does the same method signature in your native code look like?

do you get this error upon first deployment or re-deploy?
do you restart tomcat after you redeploy your jni app?

Hi Dennis.
So do you see the Load library successful message?
Also, if I remember correctly, the code in eval.java is not a safe way to
load a native library. It's a very good idea to place the
System.loadLibrary
in a static { } block, instead of in a method. The way your class is
written, it's possible for the run method to be executed more than once, in
which case loadLibrary will be called more than once (and so will the
native
initModels). Not sure what the effects are and if it's related to your
problem but it's a good idea to avoid trouble by fixing it.

IIRC, native libraries can be loaded only once,
but webapplication classloader is disposed and recreated each time the
web application is stopped/reloaded. Thus the class that loads your
library must be in ${catalina.base}/lib folder (and at the same time
it must be removed from the webapp, because otherwise the classes in
webapp are preferred over the ones in lib).

Had You tried to made c header by javah -jni
./your_packages/your_class.class ?
It gives header for You with properly named method to be written in c..

do you get this error upon first deployment or re-deploy?
do you restart tomcat after you redeploy your jni app?

Hi Dennis.
So do you see the Load library successful message?
Also, if I remember correctly, the code in eval.java is not a safe way to
load a native library. It's a very good idea to place the System.loadLibrary
in a static { } block, instead of in a method. The way your class is
written, it's possible for the run method to be executed more than once, in
which case loadLibrary will be called more than once (and so will the native
initModels). Not sure what the effects are and if it's related to your
problem but it's a good idea to avoid trouble by fixing it.

How do I run without an X server and still get graphics?
You either need to run headless or run an alternate X-server. [...] if
your are using a JVM 1.4 or better, you can use the system property
java.awt.headless=true
Indeed, isHeadless() returns true for my Java 5 and 6 installations.
import java.awt.GraphicsEnvironment;
// http://mindprod.com/jgloss/headless.html
public class Headless {
public static void main( String[] args) {
boolean headless = GraphicsEnvironment.isHeadless();
System.out.println( Ohne Tastatur, Maus, GUI? + headless);
String p = java.awt.headless;
System.out.println( p + ? + System.getProperty( p));
}
}
The iText color test (which produces graphics in a PDF) still works when
I specify java.awt.headless=false, which also makes isHeadless() return
false. So it seems to work with or without this headless property. So
why does it not work for Method8 (the OP)?

Re: java.lang.UnsatisfiedLinkError: running tomcat on java headless?
1) Are you passing -Djava.awt.headless=true to tomcat via CATALINA_OPTS
(or JAVA_OPTS)
2) I have found that even if you are headless, you can't use all the
Graphics/awt stuff. I wish I could recall what it was, but I thought the
death was in similar manner. (But this was also a few years ago). Of
course - since you are using iText - this shouldn't be an issue.

I develop on windows and deploy on a debian machine, and had some problems in the past with policies and socket permissions. You might want to consider developing on the same platform you are targeting for production. Yes, Java is supposed to run everywhere but there are certain environmental factors that can ruin your day (like X libraries). Note that Microsoft Windows always has X-ish capabilities available because the console runs a windowing system. Running Java headless doesn't mean X is not required: it just means that X doesn't have to be /running/. Some X libraries may still be required to use certain functions. You used to have to run xvfb if you wanted any kind of AWT interaction. Now, that restriction has been lifed (by going headless) but I think the libraries still need to be available. Have you tried asking the iText folks? They are much more likely to know the answer to this. Tomcat, as you might guess, has no requirements for X whatsoever. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqb5WkACgkQ9CaO5/Lv0PA1xwCfcWn86XD/yEbT/ziF4BgKFupF zvkAnijcPFMmiPoep+bJlOoZVhY98aPk =XXgx -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
