I have been working on creating a simple Java desktop app using the RESTful API for Business Objects and have run into an issue. Whenever I run my app in Eclipse in works fine; whenever I export it as a 'Runnable Jar' and select the Library handling option 'Package required libraries into generated JAR' it works fine. However, whenever I try to export it using the Library handling option 'Extract required libraries into generated JAR' I get the following error after running the app:

 java.lang.NoClassDefFoundError: Could not initialize class com.businessobjects.bcm.BCM

I have the 'bcm.jar' file added under a 'res' Source Folder and have it added to the Build Path. At one point I added all the JARs under the 'SAP BusinessObjects' java folder, and external folder, but it still throws the error. The problem stems from this line of code:

 enterpriseSession = CrystalEnterprise.getSessionMgr().logon(userID, password, CMS, auth);

Would anyone know why I am getting said error? I really want to use the Extract option as it will improve performance as my app becomes larger. Any help resolving this issue would be greatly appreciated :)

EDIT: I would be happy to provide clarification or further detail upon request!

  • From https://stackoverflow.com/questions/9617420/difference-between-extracting-and-packaging-libraries-into-a-jar-file , the Main class is different in the two cases. – mikep Jun 24 '17 at 12:52
  • Hey mikep, thank you commenting :) I have looked at that exact post in the past and it is in part why I would like to use the Extract method over Packaging. While I understand the difference between packaging and extracting, I do not understand why this bcm.jar has issues when dozens of other SAP jar's do not. The only time I have trouble packaging my app is when I use this jar; I am trying to see if there is a way I can still package my app while using this jar. – Drew B Jun 24 '17 at 17:01
  • What does META-INF in bcm.jar look lijke (jar tvf)? – mikep Jun 24 '17 at 19:59
  • When I unzipped bcm.jar the manifest contained the following: `Manifest-Version: 1.0 Ant-Version: Apache Ant 1.7.0 Created-By: 20.12-b01 (Sun Microsystems Inc.) Product-Name: Business Objects BCM (C) Implementation-Title: Business Objects BCM Implementation-Version: 14.0.0.000 Implementation-Vendor: Business Objects, Inc.(C) Class-Path: cryptojFIPS.jar external/cryptojFIPS.jar` Please note that I have 'cryptojFIPS.jar' in the same folder as bcm.jar, and have it added to the Build Path of this app. – Drew B Jun 24 '17 at 20:45
  • So when you extract this MANIFEST.MF gets replaced? In your extracted jar, what does MANIFEST.MF look like? – mikep Jun 24 '17 at 21:00
  • When I extract my application the resulting jar only display's the following for the manifest when I unzip it: `Archive: C:/Users/Drew/Desktop/Application.jar inflating: META-INF/MANIFEST.MF`. It doesn't contain a `Rsrc-Class-Path` or anything like the packaged jar does. – Drew B Jun 24 '17 at 21:25
  • Cool. That's it. Could you replace the manifest with that from bcm.jar and try again? – mikep Jun 24 '17 at 23:01
  • Unfortunately I am not familiar with moving Manifest files from Jar's like that. The bcm.jar file is a SAP jar, and Eclipse creates the manifest file of my application automatically when I export it as a jar. Might you be able to explain how to get the manifest from bcm.jar, and replace it with the manifest in my application jar? – Drew B Jun 25 '17 at 00:08
  • In your META-INF directory in Eclipse, is there a MANIFEST.MF? – mikep Jun 25 '17 at 01:36
  • Unfortunately this cannot be done in Eclipse as I need a Runnable Jar, and while exporting Eclipse generates a MANIFEST.MF file automatically that will override any MANIFEST.MF file you currently have. Are there any other suggestions for fixing this issue? – Drew B Jun 26 '17 at 14:17

Seems this was introduced in SP04 and SAP has no intent of fixing it as the RESTful API wasn't designed to be used with Desktop apps.

Have you included the cryptojFIPS.jar? Leaving it out can cause the error.

  • Hello fhossfel. Yes, I have included the cryptojFIPS.jar file under my 'res' folder and it is part of the Build Path. – Drew B Jun 28 '17 at 13:21
  • i'm just guessing but have you checked whether the bam.jar or the cryptojFIPS.jar contain other resources (like xml config files) that are not included in the unified jar? – fhossfel Jun 29 '17 at 21:39
  • From what I've seen the bcm.jar and cryptojFIPS.jar files only have classes under them, no XML files or anything. – Drew B Jun 30 '17 at 17:18
