public static String upperFirstChar(String string)

Changes the first letter of the passed String to upper case.

dbNameToClassName

public static String dbNameToClassName(String columnName)

Converts a database name to a Java class name. The naming conventions used to allow for this are as follows: a database name (table or column) is in all capital letters, and the words are separated by an underscore (for example: NEAT_ENTITY_NAME or RANDOM_FIELD_NAME); a Java name (ejb or field) is in all lower case letters, except the letter at the beginning of each word (for example: NeatEntityName or RandomFieldName). The convention of using a capital letter at the beginning of a class name in Java, or a lower-case letter for the beginning of a variable name in Java is also used along with the Java name convention above.

Parameters:

columnName - The database name

Returns:

The Java class name

dbNameToVarName

public static String dbNameToVarName(String columnName)

Converts a database name to a Java variable name. The naming conventions used to allow for this are as follows: a database name (table or column) is in all capital letters, and the words are separated by an underscore (for example: NEAT_ENTITY_NAME or RANDOM_FIELD_NAME); a Java name (ejb or field) is in all lower case letters, except the letter at the beginning of each word (for example: NeatEntityName or RandomFieldName). The convention of using a capital letter at the beginning of a class name in Java, or a lower-case letter for the beginning of a variable name in Java is also used along with the Java name convention above.

Parameters:

columnName - The database name

Returns:

The Java variable name

javaNameToDbName

public static String javaNameToDbName(String javaName)

Converts a Java variable name to a database name. The naming conventions used to allow for this are as follows: a database name (table or column) is in all capital letters, and the words are separated by an underscore (for example: NEAT_ENTITY_NAME or RANDOM_FIELD_NAME); a Java name (ejb or field) is in all lower case letters, except the letter at the beginning of each word (for example: NeatEntityName or RandomFieldName). The convention of using a capital letter at the beginning of a class name in Java, or a lower-case letter for the beginning of a variable name in Java is also used along with the Java name convention above.

Parameters:

javaName - The Java variable name

Returns:

The database name

packageToPath

public static String packageToPath(String packageName)

Converts a package name to a path by replacing all '.' characters with the File.separatorChar character. Is therefore platform independent.

public static String induceFieldType(String sqlTypeName,
                                     int length,
