Support for Java transformers and filters #20

Closed rbeckman-nextgen closed 4 years ago

rbeckman-nextgen commented 4 years ago

Currently Mirth only supports JavaScript transformers. Mirth should be ammended to allow users to use Java as the language for their transformers for the following reasons:

  1. Familiar Syntax
  2. Error Checking/Exceptions
  3. Native Objects
  4. Performance
  5. Debugging capability

In the majority of Mirth cases, 90% of the "heavy-lifting" is performed in the transformer/filter, so it makes sense to allow the option for a more robust language, as well as the performance factor by running native Java code, rather than translated Rhino Javascript.

Users should be given the option to point their transformers to a pre-compiled Java class file that adheres to our interface, or specify Java code directly that we will pre-compile on the server (using sun.tools.javac.Main when the channel is deployed to the server).

With the ability to run Java code from the Javascript, this is partially resolved.

  1. Syntax is 99% the same
  2. Error checking can be used (JS style) exceptions can be thrown
  3. Rhino treats Java objects as "native"
  4. JS Performance is improved by pre-compiling scripts
  5. Inability to debug JAVA from UI

With the ability to drop JARs dynamically into the Mirth custom folder, Java business logic can be included in a Jar and called from the JS with the following syntax:

Packages..className

I recommend this issue is closed.

Calling custom java code from jars in lib folder has been successfully tested (import packages). Resolving issue.
