How to use the license.jar

[marcht...@gmail.com]

Hello!

I am currently trying out JNI Wrapper and using an evaluation license. I received the distribution archive and license file through my email. I have extracted everything on my project lib folder with the license file and referenced them to my project build path. I tried to run my application and it returned a RuntimeException JNIWrapper license check failed: No valid license found. I have tried the solutions posted here in the forums but nothing seems to resolve my issue. One thing I noticed is I received a license.jar file instead of a JNIWrapper.lic. Thank you for any help in advance.

Best regards.

Hi,

To configure the JNIWrapper licence, you need to add the license.jar to the class path of your application.

As described in the Programmer's Guide, the licence can be located inside any JAR file that is present in the class path:
https://www.teamdev.com/downloads/jniwrapper/docs/JNIWrapper-Programmer's-Guide.html#AEN172

The license.jar is a JAR file that already contains the licence in the required location, therefore, there is no need to modify the existing JARs or create a separate one yourself.

Could you please try this approach and let us know whether the issue is resolved?

Sincerely,
Anna

Hello Anna,

Yes, I have added a classpath entry for the license.jar by adding it on my project's build path.

/ComboReaderTest/.classpath

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src">
<attributes>
<attribute name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY" value="ComboReaderTest/src"/>
</attributes>
</classpathentry>
<classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="lib" path="lib/antlr.jar"/>
<classpathentry kind="lib" path="lib/jniwrap-3.13.jar">
<attributes>
<attribute name="javadoc_location" value="jar:platform:/resource/ComboReaderTest/lib/javadoc/jniwrapper.zip!/"/>
<attribute name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY" value="ComboReaderTest/lib"/>
</attributes>
</classpathentry>
<classpathentry kind="lib" path="lib/jniwrap-generator-3.13.jar"/>
<classpathentry kind="lib" path="lib/license.jar"/>
<classpathentry kind="lib" path="lib/slf4j-api-1.5.8.jar"/>
<classpathentry kind="lib" path="lib/slf4j-simple-1.5.8.jar"/>
<classpathentry kind="con" path="org.eclipse.jdt.USER_LIBRARY/JGoodiesLibs"/>
<classpathentry kind="output" path="bin"/>
</classpath>

I placed the license.jar, jniwrap.dll and other JNI dependencies in one location which is the project's /ComboReaderTest/lib folder as described in Installation Instructions.

 I also tried passing -Dteamdev.license.info=true into my debug configuration VM arguments to see the license debug information as described in Gathering Information about Licence Errors. This is my console log:

JNIWrapper license check failed: No valid license found. 

java.lang.RuntimeException: JNIWrapper license check failed: No valid license found. 

JNIWrapper license check failed: No valid license found.
