fop 2.1 在 weblogic 服务器上加载字体时达到 EOF

Question

我有一个生成 PDF 文件的网络应用程序。我为此使用 fop 2.1，但有些字符不是默认的 fop 字体。我尝试使用其他字体，以正确打印所有字符。

如果我在我的 PC 上执行的测试类中尝试，一切正常。但是如果应用程序尝试在 weblogic 服务器上做同样的事情，我会收到： java.io.EOFException: 到达 EOF，文件大小=23275952 偏移量=23275954 错误。

我的 fop 配置（我在测试和应用中使用相同的配置）：

<fop version="2.1">
    <use-cache>false</use-cache>
    <renderers>
        <renderer mime="application/pdf">
            <fonts>
                <font embed-url="urkunde/ClearSans-Regular.ttf" kerning="yes">
                    <font-triplet name="ClearSans" style="normal" weight="normal" />
                </font>
            </fonts>
        </renderer>
    </renderers>
</fop>

我在服务器尝试加载字体时收到的错误：

我也试过其他字体。这在我测试时运行良好，但在服务器上我收到了 NegativeArraySizeException。

我不知道我错过了什么。

有什么建议吗？

Answer 1

我解决了。问题是，字体在耳朵和 war 文件中。如果该字体仅在服务器上，则可以正常工作。

Answer 2

另一种解决方案是在 maven 配置中跳过 ttf 过滤：

<plugin>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.5</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <nonFilteredFileExtensions>
            <nonFilteredFileExtension>ttf</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>

使用此配置，您可以将 ttf 保留在 ear/war 包中。
