RE: [Wrapper-user] can I use JNI from wrapper

[Carl, R. <Ca...@pg...>]

Thanks!  I had put the vendor.dll into the same directory as the
wrapper.dll, but then I forgot there was also a .dll for the JacoZoom COM
wrapper.  I was just afraid there was some conflict or restriction between
the Java Service wrapper and the JacoZoom usage of JNI.

At first blush it looks like one of your jars is missing from the classpath.

Did you add your classpath element(s) wrapper.conf?

wrapper.java.classpath.[n]=relative_path_to_your_jar(s)

 

Then, do you have the native DLLs in your path?

Try adding this to wrapper.conf:

wrapper.java.library.path.[n + 1]=relative path to vendor.dll & others

 

For my app I also had to add the following:

wrapper.java.library.path.2=../../jdk/bin

Subject: [Wrapper-user] can I use JNI from wrapper

I am working on a Java application that uses a MS VB COM vendor.dll API for
accessing vendor proprietary files.  Everything is working good standalone.
I just tried it from within a wrapper without success.  At the point of
instantiating the class that invokes the COM vendor.dll, I get:
