Using a third party Jar file for Database connection

Using a third party Jar file for Database connection

I imported the relational database extension for DB2 connectivity, but the default JDBC driver class isn't what my organization uses to connect to DB2. We use another driver class called "com.ibm.as400.access.AS400JDBCDriver".  I tried setting this in the JDBC Driver Class Name field in the DB2 Thing configuration, but I wasn't able to query a database.  I have a Jar file that we typically have to deploy to use this DB2 connection driver and I assume I have to deploy this Jar file so that ThingWorx can see it and know it exists when I try to make a connection to a DB2 database.

How do I deploy Jar file with ThingWorx/Apache so that I can use this JDBC driver?

Here are my settings (some information has been generalized):

Re: Using a third party Jar file for Database connection

Hi,

You may build your own jdbc package/extension:

  • Download the Extension Metadata file Here
  • Download the appropriate JDBC driver
  • Build the extension structure by creating the directory lib/common
  • Place the JAR file in this directory location:
    • lib/common/<JDBC driver jar file>
  • Modify the name attribute of the ExtensionPackage entity in the metadata.xml file as needed
  • Point the file attribute of the FileResource entity to the name of the JDBC JAR file
  • The metadata also contains a ThingTemplate
  • the name is set to MySqlServer, but can be modified as needed
  • Select the lib folder and metadata.xml file and send to a zip archive
    • Tip: The name of the zip archive should match the name given in the name attribute of the ExtensionPackage entity in the metadata.xml file
  • Import the newly created extension as usual
  • To the JDBC extension, simply create a new thing and assign it the new ThingTemplate that was imported with the JDBC extension

Configuration Field Explanation:

  • JDBC Driver Class Name
    • Depends on the driver being used
    • Refer to documentation
  • JDBC Connection String
    • ​Defines the information needed to establish a connection with the database
    • Connection string examples can be found in the ThingWorx Help Center
  • ConnectionValidationString
    • ​A simple query that will work regardless of table names to be executed to verify return values from the database
  • Alternatively, the ThingWorx Marketplace has a JDBC Connector Extension where you can upload and import third party JDBC drivers into the platform

Alternatively, you may download the jdbc connector creator from the marketplace here https://marketplace.thingworx.com/Items/jdbc-connector-extension

Then you may just view the mashup and use it to package your jdbc jar into an extension (which can be later imported into Thingworx).
