You get an argument cannot be null exception when you add the step to a transformation, do not fully configure the step, particularly the output fields, save the transformation, close and reopen the transformation, then try to edit the step.

Environment:
Fedora 20
PDI v5.0.1-stable
java version "1.7.0_45"
"Get JDBC Metadata" step plugin downloaded from marketplace

Error:
When adding the Get JDBC Metadata step and then saving the transformation, I get following error message:
Error saving file: java.lang.NullPointerException

Removing the step and then saving the file works.

This is what it shows in the Error details window:

I am trying to execute a transformation in Java using the Pentaho SDK. If your pentaho-pdi-plugin-jdbc-metadata is used in a transformation, it seems that this step won't set the ouput fields correctly. This is only the case when started from Java. When the same transformation is executed using Spoon, everything seems to work fine. To verify that this problem is not caused by "wrong usage", we used your example code that can be found when downloading your plugin source code from git.

Concrete case:

Tha example transformation "generate-scd2.ktr" has been executed in Spoon without any problems.
In Java, the following code has been used to execute the transformation:

    KettleEnvironment.init();
    TransMeta transMeta = new TransMeta("/home/mhe/Downloads/test/generate-scd2.ktr", (Repository) null);
    transMeta.setParameterValue("CATALOG_NAME", "el2export");
    transMeta.setParameterValue("SCHEMA_NAME", "el2export");
    transMeta.setParameterValue("TABLE_NAME", "meldung");
    Trans transformation = new Trans(transMeta);
    transformation.setLogLevel(LogLevel.DETAILED);
    transformation.execute(new String[0]);
    transformation.waitUntilFinished();

The log output looks like that:

log4j:WARN No appenders could be found for logger (org.apache.commons.vfs2.impl.StandardFileSystemManager).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

It would be nice to expose index info.
Then you can do a full compare of a schema, tables, columns and types, indexes.

Looks like the call is there..
https://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getIndexInfo(java.lang.String,%20java.lang.String,%20java.lang.String,%20boolean,%20boolean)

(ps: is this the right place, or have Pentaho "adopted" this plugin now, and therefore need to be raised there?)

I'd like to know the Kettle Datatype in addition to the database datatype. Could that be added?

It would save us re-doing the already existing mappings from e.g. VARCHAR->String etc.

Is it even possible? Does it make sense as to why? (Essentially I'm using the data to metadata inject, so obviously i need PDI datatypes for that to make sense.)

The step has trouble serializing to the Pentaho Enterprise Repository.

In particular:

• output fields are not restored when reading from enterprise repository

When exporting from file-based repository and importing to Enterprise Repository:

• boolean values are not preserved after import (i.e. "always pass input row" checkbox)

• empty method arguments cause the total list of arguments to be truncated after import
  example: show tables with

  • catalog: [empty]
  • schema pattern: %
  • name pattern: %
  • table type: TABLE

  results in table type not being preserved after import

Hi, When i run this transformation after i download it from wiki it throws an exception org.pentaho.di.trans.steps.Mappinginput.processRow.
Unable to connect with parent transformation after 60 second
Please help
