Error connecting Java to SQL Anywhere database

I am trying to connect a java program to a database. I have sajdbc4.jar in the build path and it worked before, but now I keep getting this error when I try to make the connection:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no dbjdbc12 in java.library.path

Can someome please help me? Can't find anything abount this issue online.

For windows find this file in your computer:
dbjdbc12.dll
For linux find this file:
libdbjdbc12.so
Put the location of this file on the java.library.path either with a command line option:
java -Djava.library.path=DIRECTORYWITHDLL ...
or using System.setProperty in your code:
System.setProperty("java.library.path","DIRECTORYWITHDLL");

For Linux, you need to add the dbjdbc12.so to java.library.path using:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/some/path/that/contain/dbjdbc12.so
this is the same for dbjdbc16 also.
Since, sybase.jdbc4 driver need this file. Please refer- https://blogs.sap.com/2014/05/02/connecting-to-sql-anywhere-using-jdbc-2/#:~:text=jar%20is%20in%20the%20classpath,Connection%20con%20%3D%20DriverManager.
Similarly, for windows add dbjdbc12.dll file.

For SQL Anywhere 17 libdbjdbc17.so was not suffiecient, it was then complaning about the next file:
failed: java.lang.UnsatisfiedLinkError: /usr/local/tomcat/native-jni-lib/libdbjdbc17.so: libdbtasks17_r.so: cannot open shared object file: No such file or directory
So I ended up adding all files from the lib64 folder from the Database client (after I installed it on some other linux machine) to my tomcat lib path and it worked.

How to get the full StackTrace when using SuperDevMode in GWT 2.7?

I use GWT 2.7 with super dev mode. When it comes to an exception the stack trace looks like the following:
SEVERE: UncaughtExceptioncom.github.nmorel.gwtjackson.client.exception.JsonDeserializationException: Unknown property 'uploadImageId'

I have a GWT project running in a GWT-PhoneGap environment on my iPhone and I use the Safari Console for Debugging.
How can I get the full stack track deobfuscated with SuperDevMode?
Edit: I also use the following flag:
-XmethodNameDisplayMode Full
It does not work.

As of GWT 2.7.0, this isn't possible. You might want to follow this GWT bug.
The -XmethodNameDisplayMode Full only applies to the browser's dev tools. So if you set this parameter and set a breakpoint in the source code, the method names of the call stack will be displayed correctly in dev tools. This doesn't affect the call stack produced by log output (which is what you posted in your question).

Try setting the compiler option style to PRETTY or DETAILED
-style Script output style: DETAILED, OBFUSCATED or PRETTY (defaults to OBFUSCATED)
see GWT compiler options

How to stop J2SSH SFTP put command from changing permissions

I get the error:
java.io.IOException: This server does not support operations to modify file attributes.
at com.sshtools.j2ssh.sftp.SftpSubsystemClient.getOKRequestStatus(Unknown Source)
at com.sshtools.j2ssh.sftp.SftpSubsystemClient.setAttributes(Unknown Source)

at com.sshtools.j2ssh.SftpClient.put(Unknown Source)
at com.sshtools.j2ssh.SftpClient.put(Unknown Source)
at com.sshtools.j2ssh.SftpClient.put(Unknown Source)
After some digging I found out that the SftpClient.put command does an automatic chmod after it uploads a file. Is there a way for me to disable this?
I know for sure the initial .put works as expected because when I check the remote server for the file, it is present and all bytes accounted for.

Ignored exception: java.security.PrivilegedActionException: java.lang.reflect.InvocationTargetException in Java Applet

I created a Java Applet which manipulates a JSP webpage's form fields. The JSP calls the Java Applet, of course.
This the error I'm getting in the Java Console, when I run my Java Applet on my JSP:
Ignored exception: java.security.PrivilegedActionException:
java.lang.reflect.InvocationTargetException
I am not calling InvocationTargetException or passing any exceptions in the code. Somehow, I managed to trace it, by painstaking trial-and-error, that the line causing the error is:
BlowfishCBC bfcbc = new BlowfishCBC(testkey, 0, testkey.length, CBCIV_START);
As a test, I disabled all code that has dependencies on the JSP, so I can just run it inside Eclipse. I created a main method to execute the Java Applet and then ran it inside Eclipse. I got no errors or warnings, at all.
I exported the same Java Applet, as a JAR, copied it to the server, restarted Apache Tomcat, went to the page on my web browser, ran the applet, and the same InvocationTargetException error occurred
What could be the problem?
Note: I am not using try..catch anywhere in my code. What can I put in the code that will capture this exception information and how do I do that?
Thank you.

trying to get pwd value from document
got pwd from document, password is 12345
is this getting here?
Ignored exception: java.security.PrivilegedActionException: java.lang.reflect.InvocationTargetException
I think that's the stacktrace. I hope that information is sufficient and helpful.

I found the problem. It had nothing to do with the code, persay. It was the manifest file.
Here was the manifest file, as it was originally created by Eclipse:
Manifest-Version: 1.0
Here it is after I modified it:
Manifest-Version: 1.0
Class-Path: blowfishj.jar
I didn't realize that the Java Control Panel is supposed to show the blowfishj.jar file in its Resources. I see my Java Applet, there, but the blowfishj.jar file was not there, until I made the change to this manifest file. I didn't realize it needed the manifest file.
I don't understand why it needs this in the manifest file and why this modification fixes it, though. Maybe someone can answer that question.
Thank you.

There is an earlier Sun bug report on this issue, with JDK 1.4
you are mostly running JDK 1.6 but take a look at the bug report.
Short Summary (gleaned from this forum) :
The Java plug-in of your browser tries
to get some .class file from the
current location (your server) and
fails because your server returns some
custom 404 page. Let's try to check
the Java console to see what really is
requested. Please, run the Java
console, set the trace level to 5
(highest level).
Enable the Java console on Windows for IE browser and see if it gives a detail on which URL is giving the 404 or some other error.
