Hi Everyone,

We need to generate akamai token. For token generation we are using EdgeAuth and need to added the dependency mentioned below.

<dependency>
<groupId>com.akamai</groupId>
<artifactId>edgeauth</artifactId>
<version>0.2.0</version>
</dependency>

Deployment is successful but bundles are in satisfied state.

I have also updated dependency in all/pom.xml and embedded in.

But getting compile time error.
Content Package Converter Exception Content Package Converter Exception Jar file can not be defined as a valid OSGI bundle without specifying a valid 'Bundle-SymbolicName' property.

Hi @deepikapatel ,

The edgeauth JAR you're trying to embed is not a valid OSGi bundle, as it lacks the `Bundle-SymbolicName` and other essential OSGi metadata, this is the reason you're encountering the error.

Update the core/pom.xml to wrap the JAR during the build:

<dependency>
<groupId>com.akamai</groupId>
<artifactId>edgeauth</artifactId>
<version>0.2.0</version>
</dependency>

<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>com.akamai.edgeauth</Bundle-SymbolicName>
<Export-Package>com.akamai.edgeauth.*</Export-Package>
<Private-Package>!*</Private-Package>
</instructions>
</configuration>
</plugin>
</plugins>
</build>

Try this and let me know if it works.

Hi @deepikapatel ,

To resolve the Akamai EdgeAuth "ClassDefNotFoundException" in AEM as a Cloud Service, you must ensure the edgeauth JAR is:

    - Properly OSGi-compliant
    - Included in your core bundle or deployed as a separate OSGi bundle
    - Built and deployed in a way that’s supported by AEM Cloud (which disallows non-OSGi JARs by default)

1. Add the EdgeAuth Dependency (core/pom.xml)

<dependency>
    <groupId>com.akamai</groupId>
    <artifactId>edgeauth</artifactId>
    <version>0.2.0</version>
</dependency>

2. Wrap EdgeAuth as an OSGi bundle

Since edgeauth is not an OSGi bundle, we need to wrap it. In core/pom.xml, use bnd-maven-plugin (instead of just relying on embedding):

core/pom.xml

Add this plugin:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.felix</groupId>
      <artifactId>maven-bundle-plugin</artifactId>
      <version>5.1.2</version>
      <extensions>true</extensions>
      <configuration>
        <instructions>
          <Bundle-SymbolicName>com.akamai.edgeauth</Bundle-SymbolicName>
          <Export-Package>com.akamai.edgeauth.*</Export-Package>
          <Import-Package>*</Import-Package>
          <Private-Package>!*</Private-Package>
        </instructions>
      </configuration>
    </plugin>
  </plugins>
</build>

3. Embed the JAR in your core bundle using maven-shade-plugin (if needed)

Only use this if you want to embed EdgeAuth inside your core bundle.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-shade-plugin</artifactId>
  <version>3.2.4</version>
  <executions>
    <execution>
      <phase>package</phase>
      <goals><goal>shade</goal></goals>
      <configuration>
        <createDependencyReducedPom>false</createDependencyReducedPom>
        <filters>
          <filter>
            <artifact>com.akamai:edgeauth</artifact>
            <includes>
              <include>com/akamai/edgeauth/**</include>
            </includes>
          </filter>
        </filters>
        <relocations>
          <relocation>
            <pattern>com.akamai.edgeauth</pattern>
            <shadedPattern>your.package.shadow.edgeauth</shadedPattern>
          </relocation>
        </relocations>
      </configuration>
    </execution>
  </executions>
</plugin>

Then import classes using:

import your.package.shadow.edgeauth.*;

Alternative: Deploy it as a separate OSGi bundle via a ui.apps sub-package.

4. Update all/pom.xml to Include Wrapped or Embedded JAR

Make sure it's embedded like this:

<embedded>
  <groupId>com.akamai</groupId>
  <artifactId>edgeauth</artifactId>
  <type>jar</type>
</embedded>

Or if shaded:

<embedded>
  <groupId>your.group</groupId>
  <artifactId>your-core-module</artifactId>
  <type>jar</type>
</embedded>

5. Deploy and Check OSGi Console

After deployment:

Visit /system/console/bundles

Confirm com.akamai.edgeauth is in Active state

No ClassNotFoundException should occur
