java – 从服务通过JACOB调用时,Office 2007无法打开文件

Source: Microsoft Office PowerPoint 2007
Description: PowerPoint could not open the file.

从excel我得到：

ERROR - Invoke of: Open
Source: Microsoft Office Excel
Description: Microsoft Office Excel cannot access the file 'c:marchenamarchena10workmarchenabatch_58288inputcontent_1.xlsx'. There are several possible reasons:

? The file name or path does not exist.
? The file is being used by another program.
? The workbook you are trying to save has the same name as a currently open workbook.

Word错误只是：

VariantChangeType failed

以下是我正在运行的,错误来自最后一行.

ComThread.InitSTA();

        slideApp = new ActiveXComponent("PowerPoint.Application");

        Dispatch presentations = slideApp.getProperty("Presentations").toDispatch();

        Dispatch presentation = Dispatch.call(presentations,"Open",inputFile.getAbsolutePath(),MsoTriState.msoTrue.getInteger(),// ReadOnly
                MsoTriState.msoFalse.getInteger(),// Untitled The Untitled parameter is used to create a copy of the presentation.
                MsoTriState.msoFalse.getInteger()  // WithWindow
        ).toDispatch();

我已经尝试在Open调用之前设置断点并且文件在那里,我实际上可以在GUI中使用PowerPoint打开它,但是当我执行步骤时抛出异常.

关于这个问题的烦人的事情是,它似乎不断发生,但是在对它进行了一段时间(重新运行相同的代码)之后,它最终成功完成,之后再也没有出现过.

进一步的研究我发现这只发生在.ppt,.doc和.xls文件中,而不是.pptx,.docx和.xlsx.据我所知,它与文件系统无关(我已经换掉了复制文件并尝试将文件放在不同文件系统上的机制).

我刚刚注意到这只发生在Java应用程序作为服务运行时,而不是在我从命令行运行catalina.bat时.
