Php Orbeon 3.9任何与表单的用户交互都会触发java.lang.NullPointerException错误

我们有一个PHP应用程序，在后台使用Orbeon向用户显示表单， 最近，我们不得不为8080端口被阻塞的用户提供解决方案，因此我们安装了jk_mod，在vhost文件中为Tomcat webapps提供服务，如下所示：

JkMount /orbeon/* geronimo_ajp13
JkMount /ops/* geronimo_ajp13

用户可以打开Orbeon文档，但一旦执行任何Orbeon操作（在表中单击、提交表单等），就会出现以下Orbeon错误：

以下是触发Orbeon操作时我的Firebug响应（200 ok）：

有人知道发生了什么吗？

该错误清楚地表明会话cookie由于某种原因没有传播。我将对此进行检查。

该错误清楚地表明会话cookie由于某种原因未被传播。我会查一查。

嗨，我今天在饼干上玩了好一阵子（看起来很可疑，这是真的），但至少我现在知道要深入研究一下，谢谢你的线索！我们的Orbeon Ajax请求头显示“Expires”与“Date”相同，在使用Apache的mod_jk之前，这些值确实有所不同（当一切顺利进行时），这是否意味着Orbeon Ajax请求立即超时？如果是，您知道我们可以在哪里手动将“Expires”值设置为未来时间吗？谢谢，我们已经花了一周的时间试图解决这个问题，我们真的被卡住了…Expires==Date对于Ajax请求来说是正常的，因为浏览器缓存Ajax请求的结果是没有意义的。我真的不认为这是你麻烦的根源。但是，您可能需要检查浏览器在这些Ajax请求中是否正确发送了JSESSIONID。该标头是缓存标头，而不是超时标头。把它定在未来的日期是错误的。这意味着Ajax请求是POST，缓存不适用于POST。为了解决这个问题，除了JSESSIONID值之外，我还必须将Cookie路径设置为/orbeon/xforms服务器，现在一切都像一个符咒一样工作，PHP代码就是这样的：

setcookie（'JSESSIONID'，不带分号的JSESSIONID值，time（）+3600*24*2，/orbeon/xforms server'）；

谢谢！您好，今天在Cookie上玩了好一阵子（看起来很可疑，这是真的），但至少我现在知道要深入研究一下，谢谢您提供的线索！我们的orbeon Ajax请求头显示“Expires”与“Date”相同，在使用Apache的mod_jk之前，这些值确实有所不同（当一切都顺利运行时），这是否意味着Orbeon Ajax请求立即超时？如果是，您知道我们可以在哪里手动设置“Expires”吗未来时间的价值？谢谢，我们正在努力解决这个问题一周了，我们真的被卡住了…Expires==Date对于Ajax请求来说是正常的，因为浏览器缓存Ajax请求的结果是没有意义的。我真的不认为这是您的问题的根源。但是您可能需要检查JSSessionID是否为c浏览器在这些Ajax请求中正确地发送了这些消息。没错。该消息头是缓存消息头，而不是超时消息头。将其设置为未来日期是错误的。这表示Ajax请求是帖子，缓存不适用。为了解决此问题，除了JSESSIONID值外，我还必须将Cookie路径设置为/orbeon/xforms服务器，现在它就像一个魔咒一样工作，PHP代码应该是这样的：
