We have imported pi4j in a kura plugin development project and pi4j jar files are kept in a separate lib folder in the same project and the same is added in the classpath under runtime tab.Now on exporting the jar file don't have the .class files . what can be the suggested solution to this issue

You should make sure that pi4.jar is also included in your build.properties in order to be part of the bundle's JAR file when it is exported.

Hello Sindhu,

When you import an external .jar to the project, let's say "libs" folder in project class-path, you have to include these *.jar files to the both "build.properties" and "MANIFEST.MF" file. I follow these steps, when I want to import external *.jar files to my Kura project,

1- Create a folder, "libs" to project classpath.
2- Place *.jar files to "libs" folder
3- Open MANIFEST.MF file and switch the "runtime" tabs
4- In this tab, there is a section called "Classpath", you can click 'Add..' button and simply select the jar files under "libs" folder you just created step 1, and finally save MANIFEST.MF file.

After that, when you export your bundle, the external jar files also exported in bundle. If, still you have an error like

"The type javax.microedition.io.Connection cannot be resolved. It is indirectly referenced from required .class files"

I suggest you to complete Example projects [1], In Serial-Example [2], there is a solution for this problem,

Quote:

Under Options, select the checkbox Use class files compiled in the workspace in addition to the checkboxes already enabled, and click Finish.

Thanks,
Said.

Hi said,
This problem resolved after adding the jar files properly. The mistake which i did was i removed the . file which came in the class path after adding the external jars.

Thanks,
Sindhu
