How to find the class in pr jar files

Hi All,

Is there a way to find the classes in pega jar files for example prpoi-3.6.jar , If I search the PR_EngineClasses table I can find these classes. I believe this jar contains the Apache POI api classes , but I'm not able to use the classes in POI api directly. does any one knows how to find the classes and methods in these pega jars , so that we can make use of it.

Thanks

A Vipin mentions the pzPackage column in PR_ENGINECLASSES should give you the information you are looking for.

Example:

SELECT pzpackage, pzclass, pzjar from pr_engineclasses

WHERE pzclass = 'HSSFWorkbook.class';

Result:

PZPACKAGE                                       

com/pega/apache/poi/hssf/usermodel

PZCLASS

HSSFWorkbook.class

PZJAR

prpoi-3.6.jar

You can use the Advanced -> ETier Runtime Environment feature in SMA to perform a Java class lookup to verify the location of a particular class and help confirm you are using what you want / expect.

Example:

  1. Go to the Advanced -> ETier Runtime Environment menu in SMA
  2. Enter the fully qualified class (com.pega.apache.poi.hssf.usermodel.HSSFWorkbook in this case) in the "Java Class Name" input field.
  3. Press the "Lookup Java Class" button.

The result of the lookup will be displayed in the bottom half of the screen showing the location of the given class name:

Java Class Lookup
Class Name com.pega.apache.poi.hssf.usermodel.HSSFWorkbook
Location pegajdbc://1589789075:0/prpoi-3.6.jar

If the class cannot be found the Location will not be given as per the example below:

This can be a useful tool when investigating or reviewing class loading or class not found issues.

Yes doing a select against pr_engineclasses table for pzJar like ‘prpoi-3.6%' will show you the classes. The jar is a repackage of apache's prpoi library and is meant for Pega's internal use only. Having said that, don't believe the source code should be different from the one you can download from apache's website if you are curious about the APIs.

Thanks Vipin , for the response .  I want to know the pega equivalent  class of POI class for example I cannot directly use org.apache.poi.hssf.usermodel.HSSFWorkbook Test= new org.apache.poi.hssf.usermodel.HSSFWorkbook(fileInputStream); in a java code it will throw error until I import apache's poi jar. I'm curious if I can use the classes in the prpoi ?
