Can you try to enable DynamicImport for this bundle ?

Hi JB,

Thanks for the help and ideas..

I have tried the import-package options as follow,

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Import-Package>
                *
            </Import-Package>
        </instructions>
    </configuration>
  </plugin>

Eventhough, I got the same issue while accessing the io.grpc.Context class. 

Also, I have used the "dynamic-import" option and loaded the io.grpc.Context bundle. But the issue still exists.

I have cleaned all the code and just added below one line logger code to test the bundle issue.

LOGGER.debug("Context class {}", io.grpc.Context.class);

This particular line does not produce any issue if I have added only grpc-context related dependency in the pom.xml.

<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-context</artifactId>
<version>1.38.0</version>
</dependency>

But If I have added grpc-protobuf jar (which have the grpc-context jar dependency internally), It producing NoClassDefFoundErrror for the io.grpc.Context class

<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-context</artifactId>
<version>1.38.0</version>
</dependency>

<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-protobuf</artifactId>
<version>1.38.0</version>
<scope>compile</scope>
<exclusions>
<exclusion>
<groupId>io.grpc</groupId>
<artifactId>grpc-context</artifactId>
</exclusion></exclusions>
</dependency>

Any Idea to resolve this bundle related issue, would be helpful to get rid of this error?

Hi,

Maybe the wrap bundle doesn’t have the correct import. It can be fixed with ?Import-Package=io.grpc… or using a wrapped bundle private package.

Subject: ClassNotFoundException thrown even after correct bundle exists
To: <discuss@...>

Hi,

I am trying to support the gNMI interfaces using the opendaylight. I have added the gNMI related java files, dependencies correctly in the opendaylight application. After the successful compilation, we are able to start the karaf application. But when we are doing the gNMI related stuff, I am getting the following error,

java.lang.ClassNotFoundException: io.grpc.Context cannot be found by wrap_file__home_verizon_gnmi_gnmi_karaf_target_assembly_system_io_grpc_grpc-core_1.38.0_grpc-core-1.38.0.jar_0.0.0

But this specific class(io.grpc.Context) exists in the grpc-context jar, that I have added correctly in the application's pom.xml file. But, still I am getting this error.

I have used the "find-class io.grpc.Context" option in the karaf application, displaying the grpc-conext.jar correctly.  But why the error showing the " _io_grpc_grpc-core" ? Is the karaf looking into the wrong bundle?

Please help on how to get rid of this issue...

Vinoth B
