jdbcrowsetimpl

jdbcrowsetimpl provides a repackaged implementation of the standard OpenJDK JdbcRowSet implementation for applications that need direct access to implementation behavior such as setConnection() without relying on the non-exported com.sun.rowset package.

Background

In Java 7, RowSetFactory was introduced as the preferred way to create JdbcRowSet objects:

• https://docs.oracle.com/javase/tutorial/jdbc/basics/jdbcrowset.html

However, JdbcRowSet objects created through RowSetFactory do not expose a setConnection() method, which can make connection reuse more difficult in some legacy or compatibility scenarios.

The standard RowSet API does provide setDataSourceName(), which can be used with a configured DataSource to support pooled database connections:

• https://docs.oracle.com/javase/8/docs/api/javax/sql/RowSet.html#setDataSourceName-java.lang.String-

Beginning with OpenJDK 9, the com.sun.rowset package is not exported from the java.sql.rowset module, which prevents direct use of that internal implementation package in modular Java runtimes:

• https://stackoverflow.com/questions/48129475/java-error-package-com-sun-rowset-is-not-visible-com-sun-rowset-is-declared

For backward compatibility and continued connection reuse through setConnection(), this project publishes the OpenJDK rowset implementation under the com.nqadmin.rowset package as a Maven artifact.

Source basis

Version 1.0.4 is based on the OpenJDK java.sql.rowset implementation from the fixed OpenJDK source tag jdk-25.0.1-ga in the openjdk/jdk25u repository:

• https://github.com/openjdk/jdk25u/tree/jdk-25.0.1-ga/src/java.sql.rowset/share/classes/com/sun/rowset

This project does not track OpenJDK master directly. Future releases should be reviewed against a newer fixed OpenJDK GA tag when appropriate.

The copied/adapted files are:

1. JdbcRowSetImpl.java
2. JdbcRowSetResourceBundle.java
3. RowSetResourceBundle.properties
4. RowSetResourceBundle_de.properties
5. RowSetResourceBundle_es.properties
6. RowSetResourceBundle_fr.properties
7. RowSetResourceBundle_it.properties
8. RowSetResourceBundle_ja.properties
9. RowSetResourceBundle_ko.properties
10. RowSetResourceBundle_pt_BR.properties
11. RowSetResourceBundle_sv.properties
12. RowSetResourceBundle_zh_CN.properties
13. RowSetResourceBundle_zh_TW.properties

Project adaptations

The OpenJDK source files are adapted for this artifact in the following ways:

• package references are changed from com.sun.rowset to com.nqadmin.rowset;
• resource bundle lookup is changed to use the com.nqadmin.rowset.RowSetResourceBundle base name;
• Java 8 compatibility is preserved where current OpenJDK source uses Java 9+ module APIs.

Java 8 compatibility

The OpenJDK jdk-25.0.1-ga version of JdbcRowSetResourceBundle uses module-aware resource lookup:

// Load appropriate bundle according to locale
propResBundle = (PropertyResourceBundle) ResourceBundle.getBundle(PATH,
        locale, JdbcRowSetResourceBundle.class.getModule());

That code is replaced with a Java 8-compatible class-loader lookup:

// Load appropriate bundle according to locale
propResBundle = (PropertyResourceBundle) ResourceBundle.getBundle(PATH,
        locale, Thread.currentThread().getContextClassLoader());

This allows the code to compile and run in Java 8 environments.

Resource bundle base name

The OpenJDK resource bundle base name:

private static final String PATH = "com.sun.rowset.RowSetResourceBundle";

is changed to the repackaged project base name:

private static final String PATH = "com.nqadmin.rowset.RowSetResourceBundle";

This uses the dot-style ResourceBundle base-name convention from current OpenJDK source while pointing to the resources included under src/main/resources/com/nqadmin/rowset/.

Build requirements

• Java 8 or later for normal compile/package builds.
• Maven 3.9.2 or later.
  • Maven 3.9.16 is recommended and was used for release preparation.
• Java 11 or later is required only when running the optional OWASP Dependency-Check profile.

Build

To build locally:

mvn clean verify

To run OWASP Dependency-Check:

mvn -Powasp-check verify

To prepare release artifacts with sources, Javadocs, signatures, and Central Portal publishing support:

mvn -Prelease clean deploy

Before using the release profile, configure the required Central Portal and GPG credentials in your Maven settings.xml.
