Issue
I'm trying to parse some JSON object strings that I'm getting using gson-1.6.jar I have placed it in the same location as my other .jars and have added it to my buildpath in eclipse.
The other libraries worked fine when I added them and I can use them without any issues, but when I try to create the JSON object, I get the titular error. I've looked through the other questions with this error, but I couldn't find a solution that didn't involve something that I've tried or something unrelated.
I import it near the top using:
import com.google.gson.Gson;
Then use it later in a static function like so:
Gson g = new Gson();
Here is my eclipse generated classpath file [Path] substituted for actual path:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jre6">
<attributes>
<attribute name="owner.project.facets" value="java"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimeTarget/Apache Tomcat v5.5">
<attributes>
<attribute name="owner.project.facets" value="jst.web"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>
<classpathentry kind="lib" path="[Path]/jabbabase-ws-jwsdp-client-2.4.7.jar"/>
<classpathentry kind="lib" path="[Path]/log4j-1.2.16.jar"/>
<classpathentry kind="lib" path="[Path]/gson-1.6.jar"/>
<classpathentry kind="output" path="build/classes"/>
</classpath>
as well as my build path window:
I'm a little lost at this point. I've tried Google and the posts basically just say to add to your build path. Anybody have any ideas?
Edit: More Info
The code referencing com.google.gson.GSON is used as a bean by a jsp. This function is called from the jsp and the error occurs as soon as the function is executed. The first line in the function is:
Gson g = new Gson();
It seems to compile and deploy fine, but when it is executed, I get the error message.
Thanks
Solution
In case of a JSP/Servlet webapplication, you just need to drop 3rd party JAR files in /WEB-INF/lib
folder. If the project is a Dynamic Web Project, then Eclipse will automatically take care about setting the buildpath right as well. You do not need to fiddle with Eclipse buildpath. Don't forget to undo it all.
