GWT Maps API V3 Core API

I'm trying to use the GWT Maps API V3 in a Spring Boot project.
I added it in gradle with no issue and wrote my code but when running, it crashes showing the following:

Any idea how to use it with spring?

From this blog, try coping commons-logging.jar file to WEB-INF/lib folder. You must also have packaged the servlet-api.jar along with the other libraries in your war file. You can verify this by opening up your war file and navigating to the WEB-INF/lib folder.
Based from this post, you should not provide the servlet-api jar. The container, in your case Tomcat, is responsible for providing it at deploy time to your application. If you try to provide it as well, then issues arise due to version mismatch etc. Best practise is to just avoid packaging it. Remove it from the WEB-INF/lib.
Also according to this thread:
Your webapp has servletcontainer specific libraries like servlet-api.jar file in its /WEB-INF/lib. This is not right. Remove them all. The /WEB-INF/lib should contain only the libraries specific to the webapp, not to the servletcontainer. The servletcontainer (like Tomcat) is the one who should already provide the servletcontainer specific libraries. If you supply libraries from an arbitrary servletcontainer of a different make/version, you'll run into this kind of problems because your webapp wouldn't be able to run on a servletcontainer of a different make/version than where those libraries are originated from.

I found that tomcat may not contain dbcp-jar, so I tried to add it via gradle:
compile 'org.apache.tomcat:tomcat-jdbc:7.0.59' but nothing changed
Can anyone explain me how it should be done?

The Java Option to run the Jacoco agent is set as:

I am not using a Maven or Ant file to run it, and the option to run the agent is set directly in the Tomcat startup script. Can anyone please help?

can't starting Tomcat v8.0 at localhost

I tried to create/run a java web app and ran into the following error. I saw that other people have had similar problems, however, I tried what they said but they all not work.

and what's in my WEB-INF/lib
Help!

add below dependency into your pom.xml
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20160212</version>
</dependency>
If you are not using maven then you have to download and add this java-json.jar to your build path

NoClassDefFoundError: org/json/JSONException means it can't find the class JSONException at runtime. Either you add it as a dependency in your pom.xml, add it to your build-path or you add the JAR to your Tomcat Lib folder.
Either way, you'll have to get the JAR containing the JSONException. Which can be found here.

I tried all the means,they all not work until I reinstall tomacat....

Tomcat can't start the app because it can't find JSONRPC2ParseException class

I have application in /var/lib/tomcat7/webapps/code I have init.java file that use json-rpc-2.0
I compile it using:
export CLASSPATH=$CLASSPATH:/path/jsonrpc2-base-1.35.jar:/path/json-smart-1.2.jar
javac init.java
it compile but when I run the app (not the servlet) I got error 404 from Tomcat and in catalina.out file there is exception:

with caused by not found com/thetransactioncompany/jsonrpc2/JSONRPC2ParseException which is in jar file.
What's happening here? How can I fix it to make it work?

This is usually the jar files are not available for Tomcat.
The best way to solve this is place the json-rpc-2.0 jar files into your Tomcat's lib folder
Update
As specified by A4L user , you can also put the jar in your web applications WEB-INF/lib as well.
