I am having issues when I am running Ofbiz it is throwing this error:

HTTP Status 500 – Internal Server Error Type Exception Report

Apache Tomcat/9.0.13

I have researched this error, and it appears to be related to either my delegator or the connection to the database, however I do not posses the skills to fix it. Can someone please help me?

I have posted the contents of my entityengine.xml

Answer 1

The cause here is easy to explain: you are auto-generating ids, which have already been taken. This causes a rollback of the entry and then a subsequent error is thrown.

Most likely you imported seed data with Ids larger 10000, which is where most auto-ids start and now a new entry will clash with the existing.

You can fix this by updating the nextseqId value (there is a table for it).

For more infos on this topic, also feel free to join the Scipio ERP community , which happens to be a modern fork of the OFBiz project,

Answer 2

Your first <delegator> opening tag is not seen in the code you have attached for entityengine.xml . Assuming you are using MySQL DB, please check if the details provided such as DB name, username, password, etc provided in <datasource name="localmysql"> is correct. Also, please check if you are able to access your DB outside of Ofbiz. ie through a DB client like SQL Yog.
