Hi David,
thank you very much for yor response. Below you can see a reduced piece of code
because the original code is to huge. But this simple Applet has the same debugging
problem:
>> AppAccelerator(tm) 1.1.034 for Java (JDK 1.1), x86 version.
>> Copyright (c) 1998 Borland International. All Rights Reserved.
>> Opening db connection ...
>> java.lang.NoClassDefFoundError
my code snippet:
...
import java.sql.*;
...
try {
Class.forName (driverName);
System.out.println ("Opening db connection ...");
*** connection = DriverManager.getConnection (dbUrl, user, passwd);
System.out.println ("Success");
}
...
I have placed a breakpoint on 'System.out.println ("Opening ...")' and it
worked so far. But when the debugger reaches the following line (***) i get
the NoClassDefFoundError message. So debugging seems to work in general.
But something must go wrong. You mentioned something about JRun jar files which
i don't understand. Please tell me more about it. Most of my jar files are located
in:
E:\JBuilder2\java\lib
E:\JBuilder2\java
E:\JBuilder2\redist
My path configuration is:
CLASSPATH =
e:\jbuilder2\lib;
e:\jbuilder2\redist:
e:\jbuilder2\java\lib;
e:\jbuilder2\myclasses;
%SWING_HOME%\swing.jar;
%SWING_HOME%\motif.jar;
%SWING_HOME%\windows.jar;
e:\programme\Borland\DataGateway\classes\DataGateway.zip
e:\Program Files\InterBase Corp\InterClient\interclient.jar;
.;
SWING_HOME = e:\jbuilder2\redist
Path =
E:\jdk1.1.6\bin;
E:\IBMVJava\eab\bin;
e:\Centura\Dbcnvt;
e:\Centura\Samples;
e:\Centura;
%SystemRoot%\system32;
%SystemRoot%;%SystemRoot%\system32\nls\ENGLISH;
c:\prg\sqlbase;
E:\IMNnq_NT;
E:\ORANT\BIN;
e:\programme\Borland\DataGateway\bin
Thanks in advance

P.S: I've forgotten to mention that i am using Netscape 4.06 with the Java Plugin
1.1.1.
I have copied all files in the redist directory to the Netscape java\classes
directory.
