我正在尝试加载一个包含图像的pdf文件（更具体地说，我的java代码通过打印一些文本和图像来生成pdf文件。图像是一个qr代码图像，它是由我的Web应用程序中的代码的其他部分生成）。当我在Eclipse中运行我的程序＆＃34;在服务器上运行＆＃34;时，没有错误，我可以使用chrome在我的localhost上看到pdf。但是，当我从我的项目中创建一个WAR文件以在本地部署我的项目并尝试在chrome中浏览pdf页面时，我在com.itextpdf.text.pdf.PdfGraphics2D.drawImage＆＃中得到了＃java; java.lang.IllegalArgumentException。 34;错误。 我注释掉了在我的java代码中在pdf文件上打印图像的部分，并重新生成了WAR文件。现在我能够看到pdf文件，但当然没有图像。我应该说我浏览我的应用程序的其他页面没有问题。 有谁可以帮助我如何解决这个问题。非常感谢任何信息。

我找到了解决问题的方法：
我认为当我使用Eclipse运行我的程序时，这样的临时文件正在某处生成而没有任何问题。但是使用WAR文件时tomcat没有权限创建“temp”文件。
