If I remove the lockType the query works
My connection string is:
jdbc:dbf:////home/app?DefaultExtension=dbf;lockType=VFP
When I access a table "under" a database (.dct) with the same parameters this error don't happen.
I already installed the libJNIFile.so.
Can you help me ?

Try
try{
java.io.File file=new java.io.File("/home/app/est/cfg.dbf");
com.hxtt.concurrent.JNIFile jniFile=new com.hxtt.concurrent.JNIFile(file,3);
jniFile.close();
}catch(Exception e){
e.printStackTrace();
System.out.println(e);
}
to see where you will get NoClassDefFoundError.
What's your OS and JDK version?

The error happens in the following line:
com.hxtt.concurrent.JNIFile jniFile=new com.hxtt.concurrent.JNIFile(file,3);
The OS is SUSE Linux 10.2
Linux version 2.6.18.8-0.1-default (geeko@buildhost) (gcc version 4.1.2 20061115 (prerelease) (SUSE Linux)) #1 SMP Fri Mar 2 13:51:59 UTC 2007
The JVM is Sun Microsystems Inc. Version 1.5.0_10-b03

Try:
try{
System.loadLibrary("JNIFile");
}catch(Exception e){
e.printStackTrace();
System.out.println(e);
}
You should get error too.

The error now is
java.lang.UnsatisfiedLinkError: Native Library /usr/lib/jvm/java-1.5.0-sun-1.5.0_update10/jre/lib/i386/client/libJNIFile.so already loaded in another classloader
Then I restarted the Tomcat and it started to work
After this I reloaded the application (using the Tomcat Manager) and the error returned.
The Tomcat version is: Apache Tomcat/5.0
What can I do to solve this ?

If there's no VFP applcation using those tables, just remove that lockType connection property.

In this case there are a VFP application sharing this tables.
I need to use the lock parameter.

That "already loaded" issue is a Java design "bug". Please download the latest package which will use NIO lock, not JNI lock, for JDK1.5 on Linux.
