Access 데이터베이스에서 테이블과 열의 압축을 풀기 위해 간단한 Java 프로그램을 작성하려고합니다. 내가 스택 트레이스 다음과 같은 출력을 얻을 그것을 실행하려고 할 때"지정된 네트워크 이름을 더 이상 사용할 수 없습니다"Jackcess 함께 작업 할 때
String sourceDatabase = "C:\\temp\\test1.mdb";
Database accessDB = DatabaseBuilder.open(new File(sourceDatabase));
// Loop through the tables
Set<String> accessTables = accessDB.getTableNames();
for (String currentTable: accessTables) {
System.out.println("Reading table " + currentTable + "...");
Table table = accessDB.getTable(currentTable); // This is line 51 where the stacktrace occurs
// Loop through columns in current table
for(Column column : table.getColumns()) {
String columnName = column.getName();
Integer colType = column.getSQLType();
Boolean isAutoNumber = column.isAutoNumber();
System.out.println("\t" + columnName + " \t" + sqlTypeToText(colType) + "\t" + isAutoNumber);
}
System.out.println("");
}
accessDB.close();

내가 노력했지만 찾지 못한 나는 다음을 가지고 한 Jackcess 요리 책을 사용하여 Jackcess와 똑같은 문제가있는 사람, 내가 뭘 잘못하고 있니?
