You need to add mysql dependency to your project. If you are using the maven project, gradle ,sbt use this link and add it into your project.
https://mvnrepository.com/artifact/mysql/mysql-connector-java/8.0.12
If you are not using any of this above download mysql-connector-java jar manually and add it in class path.
you can download jar from here https://www.mysql.com/products/connector/
I get an error while using import javax.microedition.lcdui.*;
package javax.microedition.lcdui.* does not exist.
But the line import javax.microedition.midlet.MIDlet;
does not give any error.
Imoprt lcdui jar file in your application library. You can download this jar file from here. Download Jar file
I'm trying to import org.apache.commons.codec.binary.Base64.encodeBase64, but Eclipse keeps telling me this import cannot be resolved, even though I've added the apache commons codec jar file to both the lib file of my project and also as an Eclipse plugin. What could be causing this issue?
org.apache.commons.codec.binary.Base64.encodeBase64 is a method. You import Types, like org.apache.commons.codec.binary.Base64.
Yesterday I was working in my project. Today when I opened eclipse there is an error:
The import org.apache.camel cannot be resolved in .java file.
I tried to add .jar file then I got another error:
The import org.springframework cannot be resolved.
Then I tried to add this .jar and I got another error. What happened overnight?
Note: There is maven integration with my eclipse.
you need to specify versions for each library defined in pom.xml file.
I'm importing several JARs all sitting in the same directory. When my program runs I'm able to access the classes in several of those JARs, no problem. So my classpath is fine (I assume). But there is one JAR giving me trouble. When I try to run:
Configuration conf = new BaseConfiguration();
I get a NoClassDefFoundError error. The searching I did on "NoClassDefFound" typically points to classpath problems but as mentioned above, other JARs in the same directory are being found so I think that's not the problem.
This is in Eclipse 3.8.
The import statements:
import org.apache.commons.configuration.BaseConfiguration;
import org.apache.commons.configuration.Configuration;
And the name of the JAR is:
commons-configuration-1.6.jar
Any ideas?
Tom
Perhaps it's failing to load a dependency of one of the classes in commons-configuration-1.6.jar? Maybe from another commons- JAR? The NoClassDefFoundError should tell you which class the runtime failed to load. Have you checked this?
