The error means that the dynamic link library (*.so) that has been loaded does 
not contain the method.

It seems that you have indicated to Netbeans a path to a file libglpk-java.so 
that is not the GLPK for Java library.

I use Maven for my Netbeans projects.

To my project pom.xml I add the following repository

    <repositories>
        <repository>
            <id>XypronRelease</id>
            <name>Xypron Release</name>
            <url>http://rsync.xypron.de/repository</url>
            <layout>default</layout>
        </repository>
    </repositories>

and the following dependency

    <dependencies>
        <dependency>
            <groupId>org.gnu.glpk</groupId>
            <artifactId>glpk-java</artifactId>
            <version>1.0.18</version>
        </dependency>
    </dependencies>

The binaries are not distributed in the repository because they are machine 
dependent.

If you do not want to download from my repository you can build and install the 
artifact with:

cd glpk-java-1.0.18
make
sudo make install
cd swig
mvn clean install

Maven 3 is required.
