Hello. I posted the same topic yesterday and didn't receive any replies. I've tried to be more specific and hopefully someone can help me. I'm having a problem editing data in a database file on my AS400. I have an application server set up on the same machine and I've created a data source to access the files in my library. The provider is "DB2 for OS400 V5R1 JDBC Provider", the database name is "*LOCAL" and the library name is correct. I can use a SELECT statement with the data source without issue, but when I try UPDATE, DELETE OR INSERT, I get an error message.

This is my code to access the file:
DataSource ds = (DataSource) (new InitialContext()).lookup("jdbc/<dataSourceName>");
Connection as400System = ds.getConnection("<userid>", "<password>");

This is my code to delete a record:
PreparedStatement editRecordPS = as400System.prepareStatement("DELETE FROM <fileName> WHERE <condition>");
editRecordPS.execute();

Thanks in advance for your help. I appreciate it. I've listed the error from error log below:
