SAP Entity Generator Exception

[gvsrini]

I installed generate-sap-entities in forge and I am able to "list" properties as shown below. After having set my properties, when I go to fetch BAPI's, it is throwing a ClassNotFoundException.

New to Forge, so have no clue if we need to set CLASSPATH somewhere. Any help will be highly appreciated.

Looks like a native library was not loaded, check the logs in ~/.forge/log/forge.log for the stacktace that caused this.

Thanks for the quick response. I am using forge-distribution-1.4.2.Final and I don't see the log file you mentioned. There is only a runtime.log in this specific version.

The latest version of forge-distribution-2.14.0.Final-offline however produces the log file you mentioned. But the latest version does not seem to support forge git-plugin git://github.com/forge/plugin-hibersap.git, hence I am using the older version. This older version looks to be tested by the plugin as per the plugin's git commit history, hence I am more leaning towards the older version of forge.

There is no additional error log generated by the older version of forge. I seem to be stuck. Forge is making my life difficult!

If it's indeed the native library issue, where do I have to put the sapjco3.dll? Can I copy it manually over to the .forge plugin directory? Do I need to add it to some XML as well?

Really appreciate your help. I am completely stuck at the fag-end of this whole effort.

Did further investigation and in summary, older version of Forge installs plugin but fails loading the dependent class with ClassNotFoundException at run-time whereas Forge 2 is not even able to install the same plugin.

I tried to install it using Forge 2 (forge-distribution-2.14.0.Final-offline) using following command:

The plugin is not compatible with Forge 2. @ivannov is the lead maintainer of this plugin and can give you more information

I reverted back to the Forge 1.4.2 and this is the exception shown. This appears to be a problem from SAP library, not a Forge plugin issue.

Based on info from here (http://stackoverflow.com/questions/24765243/sapjco-3-0-11-with-maven-it-is-not-allowed-to-rename-or-repackage-the-original), SAP does not seem to be allowing renaming the jar (to suit Maven notations). My SAP JCo version is 3.0.12 and the problem mentioned in SO refers to 3.0.11. My hunch is that this "feature" has been introduced in newer versions of SAP JCo.

Can someone suggest how we can use a Non-mavenized SAP JCo jar in Forge environment.

***ERROR*** Exception encountered: JCo initialization failed with java.lang.ExceptionInInitializerError: Illegal JCo archive "sap-jco-3.0.12.jar". It is not allowed to rename or repackage the original archive "sapjco3.jar". (type "set VERBOSE true" to enable stack traces)

[gvsrini]

Confirmed. The generator runs fine with sap-jco 3.0.7 version, but not with 3.0.12. It appears sapjco3.jar file name is not supposed to be changed [to sap-jco-3.0.xx.jar] in the new scheme of things.

[cerker]

This is an issue starting with SAP JCo 3.11.0. It now checks if the jar name is sapjco3.jar.
See also https://sourceforge.net/p/hibersap/discussion/813164/thread/52913577/

Handling the JCo dependencies with Maven already was a bit complicated since they can not be found in any public Maven repo, now they made it even worse. Hope it works with the suggestion in the above mentioned sourceforge discussion topic.
