Access methods of one par file in another par file

[Ramma]

Hi All,

I want to access methods a PAR file in another PAR file.

-> I create a JSPdynpage application withname Aapp with "A_Dynpage and A_Jsppage". This is working fine.

-> Created another Dynpage Bapp... opened Bapp application's portalapp.xml in sharingreference added Aapp.
right click on Bapp -> properites -> Java Buildpath -> Projects and selected Aapp application form the list.

-> In Bapp application's java file... I am trying to access Aapp application's methods. Aapp application, Aapp Dynpage are autofilling (ctrl+space) in Bapp java/jsp file. but when I deployed and executed Bapp application its giving me
java.lang.NoClassDefFoundError: Aapp
but while writing the code, Aapp methods are coming by auto fill.

Do I need to do anything more other than changing portalapp.xml and slecting 1st application in projects tab of java build path???

Thanks,
Ramma

Hi Ramma,

Check the following\

1) see whetehr any jars are missing (i.e you would have used some jars in appa but not add in appb).
2) Pleast go to the error trace file and paste the exception that you are getting. The error log file will say for what class this error is thrown.

Hi Ramma,

In order to be able to access the methods during runtime, the class must be located in the src.api area of the project. If located in src.core, another application cannot call the method even with a Sharing Reference.

Hi,

Golfi: I am not using any jar files in any of the components except the standard and htmlb jars.

Micro : I did as you said, I created another JSPDynpage where class is in src.api folder. but still I am getting the exception.
both applications working fine individually, but when I access Aapp from Bapp then Bapp is giving below exception. exception log
