我们通过Java Web Start启动了一个支持Spring的java桌面应用程序.
JNLP已正确创建和下载,但在服务器http日志中,我们在一些未发布的库(org.springframework.core.jar和org.springframework.beans.jar)上看到404错误：

从时间戳差距(/ – 10s),我怀疑下载是在春季上下文加载时发生的.但我无法弄清楚为什么.

有什么建议吗？

编辑：
值得注意的是,此行为不是阻塞问题：应用程序正常运行.但是,服务器日志很快就会填充404.

这是从服务器下载的JNLP文件.我非常有信心它是可以的(已经用JaNeLA检查过了),它肯定不包括404’d库.

解决方法:

您应该尝试使用-verbose：class JVM参数运行,这将告诉您哪个类导致加载哪个webstart.这是webstart允许的(但我发现webstart中的JVM参数通常不遵循文档).

通常,除非在jnpl文件中指定jar(或在您自己引用的jnlp文件中),否则不会从URL加载jar.所以你可以去做那些手动检查.
