I am experiencing difficulty running the Java sample apps both in an IDE and from the command line. I get a java.lang.UnsatisfiedLinkError when I try to call RegisterClientApp. I debugged it (and added a try/catch block) and the iq_jni library loads without error in the IQ_32 class. However RegisterClientApp throws this error. The ~DTN\IQFeed directory is in my PATH. I also made it my project directory when trying to run through the IDE. Both IDE and command line throw this linking error. Is there another step I have to take after loading the library to be able to call the native methods on the superclass?

Hello, reworking the java example apps is something that we intend todo in the upcomming releases. They are certianly primative in thier current form.

It also appears there may be a bug with what is currently being distributed.

Here is what I did to get them running from a fresh instal of IQFeed.

from the iqfeed installed directory, copy the "com" directory (and all sub directories) into the
/Java Examples/tc/ directory

so your directory structure should now look like:
\DTN\IQFeed\JAVA Examples\tc
\DTN\IQFeed\JAVA Examples\tc\com
\DTN\IQFeed\JAVA Examples\tc\LookupClient.class
\DTN\IQFeed\JAVA Examples\tc\LookupClient.java
\DTN\IQFeed\JAVA Examples\tc\streamer$stream_thread.class
\DTN\IQFeed\JAVA Examples\tc\streamer.class
\DTN\IQFeed\JAVA Examples\tc\streamer.java
\DTN\IQFeed\JAVA Examples\tc\com\iqfeed
\DTN\IQFeed\JAVA Examples\tc\com\iqfeed\IQ_32.class
\DTN\IQFeed\JAVA Examples\tc\com\iqfeed\IQ_32.java

At this point, the applications should be able to find the IQ_32 class properly.

However, I also had to edit the example apps to comment out the first line that says "package tc;" and recompile it.

at this point I was able to run both example apps that are provided.

does this help?

It helped a lot. Thanks!!
