RE: Tomcat loading dlls
Just one thing I forgot to ask.
Using the PATH Variable works fine when starting the Tomcat from a command
shell.
Nevertheless if I start the Tomcat from within Eclipse (MyEclipse), it does
not care if the directory is specified in the PATH or not. The DLL is not
being loaded. In order for it to work I have to append the directory to the
"library path" when starting the Tomcat from within Eclipse.
Why is this so? Am I doing something wrong? I mean it is the same Tomcat.
Just once started from within Eclipse.
Thanks in Advance!

RE: Tomcat loading dlls
Using the PATH Variable worked fine.
Just some quick questions for a better understanding:
If a Java program calls System.loadLibrary("XXX"), are all directories
specified by the PATH varibale searched for a DLL called XXX? In case there
are more directories specified that do contain a DLL called XXX, which one
is taken? The first occurence specified in the PATH Variable, the last one?
Can anyone explain the difference between PATH, CLASSPATH and
java.library.path. I am a little stuck on when to use use which property.
Thanks in Advance for your time!

Tomcat loading dlls
Hi Everybody, I have a web application deployed into tomcat which needs some dlls during execution. These dlls are being included in the java code statically and use system.loadlibrary(...) to be loaded. If I place the needed dlls into Tomcat's bin directory they are found and loaded successfully during startup. Now I know that this is not regarded as a good practice. So my question is. What is the best practice? What is the best way to go? Do I place the needed dlls into another directory and alter an environmental variable (f.e. java.library.path, PATH, CLASSPATH, ...) or do i alter catalina.bat/startup.bat? Seriously, what is the prefered solution? Thanks in Advance for your time!

Tomcat 6 + Native Library + HTTPS
Hi Everybody! Can anyone tell me - or give me a resource - on how to configure SSL in Tomcat 6 with an installed Native Library? I did it as usual in the following way: But Tomcat refuses to start up. As soon as I remove the Native Library, these settings work perfect. Where and How am I getting wrong? Thanks in Advance for both your time and your knowledge!
