java – com4j包装器gen问题

导读：我正在尝试使用tlbimp-20110320.jar为com4j生成包装器.我也尝试了同样错误的2008版本.即使我尝试运行tut中的示例,我也会遇到相同的错误. C:UsersmatthewDocumentsNetBeansProjectstest"C:Program Files (x86)Javajre7binjava.exe" -jar tlbimp-201

在Iceman提供了一个指向所需库的链接后,我能够让它运行一点.但是我不得不将arg4j内容复制到tlbimp jar中,并将com4j内容复制到tlbimp jar中.现在我明白了

解决方法

tlbimp-20110320.jar需要 args4j-2.0.1.jar和 com4j-20110320.jar
注意：com4j-20110320.jar,有必要将名称更改为com4j.jar

附加信息

最新版本(tlbimp-2.1.jar)的tlbimp需要args4j-2.0.8.jar和com4j-2.1.jar.在此版本中,不需要更改文件名.
