Re: [Dev] ClassNotFoundException : org.wso2.carbon.student.mgt.GetStudents when creating carbon component.
Hi all,
Sorry for the late reply on this. There were 2 issues with what I had done.
Issue 1 - ClassNotFoundException :
org.wso2.carbon.student.mgt.GetStudents - Was able to get this fixed by
removing the version tag of the maven-bundle-plugin plugin.
Issue 2 - The name was not shown properly in the side bar of the carbon
site. - In components.xml, the end tag of the i18n-bundle element was
on another line. This caused the menu item to show as student.menu rather
than as Students.
Thanks for all the help.

Hi Hemika,
Expand the deployed student management stub osgi bundle and check whether
GetStudents.class class file is in it.
Thanks

Hi Hemika, Can you attach the StudentManagerClient.java file. It seems the problem is caused from there.

Hi Supun,
I have attached the request file. Please note that in eclipse it shows
several error in 2 import lines and others. But the build gets succeeded
when using Maven.
Hi Chamin and Shashika,
The contents are the same as it is mentioned in the tutorial. I also
noticed the issue. But couldn't find a reason.

Re: [Dev] ClassNotFoundException : org.wso2.carbon.student.mgt.GetStudents when creating carbon component.
Hi,
Class loading problems occur if multiple osgi bundles contain the same java
package (unless they are added as fragment bundles). Check whether the 3
bundles you have added contain a common package.

Re: [Dev] ClassNotFoundException : org.wso2.carbon.student.mgt.GetStudents when creating carbon component.
Hi Hemika,
Expand the deployed student management stub osgi bundle and check whether
GetStudents.class class file is in it.
Thanks

Hi,
Class loading problems occur if multiple osgi bundles contain the same
java package (unless they are added as fragment bundles). Check whether the
3 bundles you have added contain a common package.
Thanks

Hi All,
I have been following this tutorial on creating a carbon component [1]. I
have created all 3 OSGI bundles and added them to the dropins folder.
Once I start the carbon server, I see the component I created as
student.menu. But when clicked on it, nothing happens. In the carbon
console I see the following error. I have also attached a copy of the tree
structure of the org.wso2.carbon.student.mgt.ui project and also the
content of the org.wso2.carbon.student.mgt.ui jar file.
The error -
