add spring jar to class path

I have a netbeans java console project which uses Spring 3.0 ( which is a bunch of jars instead of a single jar).

when i try to execute it from the command line i get

 Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext
Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:307)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: com.aosprojects.transportservice.runner.InitialRunner. Program will exit.

How to fix this?

I have tried using -c开发者_StackOverflowp to specify the folder with all the jars in it like

java -cp libs/spring/* -jar dist/XXXXX.jar

If you're using maven to build your application, it runs in the netbeans IDE, but you'll need to define a plugin in your maven pom.xml in order to include all of the required .jars in your final .jar to make it executable.

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>yourmainpackagename.YourMainClass</mainClass>
                        </transformer>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                            <resource>META-INF/spring.handlers</resource>
                        </transformer>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                            <resource>META-INF/spring.schemas</resource>
                        </transformer>
                    </transformers>
                </configuration>
            </execution>
        </executions>
    </plugin>

This approach uses the maven shade plugin. You could also be using the maven assembly plugin, be prepared to face nasty bugs though :p

cheers.

If you are compiling using Netbeans IDE (with proper build path) then build artifact (the jar) and the lib/ would be in dist directory.

cd into the ${project-root}/dist directory and then run :

java -jar XXXXX.jar

The dependency on the libraries must be already taken care of in MANIFEST by Netbeans.

PS: See the generated README in the dist directory.

Here's my directory structure:

~/downloads/
|--libs
---|--spring
------|--org.springframework.expression-3.1.0.M1.jar
------|--org.springframework.context-3.1.0.M1.jar
------|--The rest of the jars
|--Spring.java

The source code for Spring.java:

import org.springframework.context.ApplicationContext;
public class Spring{ public static void main(String... args){ ApplicationContext ac; System.out.println("Successfully declared reference of type ApplicationContext. Exiting...");}}

Navigate to ~/Downloads/ and execute the following:

javac -cp "libs/spring/*" Spring.java
jar cvfe Spring.jar Spring Spring.class
java -cp ".:libs/spring/*" -jar Spring.jar

Output:

Successfully declared reference of type ApplicationContext. Exiting...

This tells you the right way to do it:

http://javahowto.blogspot.com/2006/06/set-classpath-in-eclipse-and-netbeans.html

Right click on project, select properties, and follow instructions. Add all the JARs you need.

If it's an executable JAR, you have to add all the dependencies properly into the manifest. Google for instructions on how to do that and give it a go.
