java - PWC1231 和 PWC6344

Question

我有两台在 Glassfish 2.1 上运行的服务器，它们都具有相同的网络应用程序。

出现两次此错误:某些jsp页面停止显示，仅显示空白页，并且在日志中打印以下错误...

PWC1231: Servlet.service() for servlet jsp threw exception java.io.FileNotFoundException: /path/to/jsp/file/jsp_file.jsp.java (Permission denied) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.(FileOutputStream.java:179) at java.io.FileOutputStream.(FileOutputStream.java:70) at org.apache.jasper.compiler.AntJavaCompiler.getJavaWriter(AntJavaCompiler.java:213) at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:173) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:409) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:592) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:344) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:470) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:364) at javax.servlet.http.HttpServlet.service(HttpServlet.java:831) at org.apache.catalina.core.ApplicationFilterChain.servletService(ApplicationFilterChain.java:411) at org.apache.catalina.core.ApplicationDispatcher.doInvoke(ApplicationDispatcher.java:855) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:703) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:542) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:474) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:366) at org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:1056) at org.apache.struts.tiles.TilesRequestProcessor.doForward(TilesRequestProcessor.java:261) at org.apache.struts.action.RequestProcessor.processForwardConfig(RequestProcessor.java:388) at org.apache.struts.tiles.TilesRequestProcessor.processForwardConfig(TilesRequestProcessor.java:316) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:231) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:415) at javax.servlet.http.HttpServlet.service(HttpServlet.java:738) at javax.servlet.http.HttpServlet.service(HttpServlet.java:831) at org.apache.catalina.core.ApplicationFilterChain.servletService(ApplicationFilterChain.java:411) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:317) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:198) at com.my.app.filtro.FiltroCallcenter.doFilter(FiltroCallcenter.java:90) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:230) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:198) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:288) at org.apache.catalina.core.StandardContextValve.invokeInternal(StandardContextValve.java:271) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:202) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:632) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:577) at com.sun.enterprise.web.WebPipeline.invoke(WebPipeline.java:94) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:206) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:632) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:577) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:571) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:1080) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:150) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:632) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:577) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:571) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:1080) at org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter.java:272) at com.sun.enterprise.web.connector.grizzly.DefaultProcessorTask.invokeAdapter(DefaultProcessorTask.java:637) at com.sun.enterprise.web.connector.grizzly.DefaultProcessorTask.doProcess(DefaultProcessorTask.java:568) at com.sun.enterprise.web.connector.grizzly.DefaultProcessorTask.process(DefaultProcessorTask.java:813) at com.sun.enterprise.web.connector.grizzly.DefaultReadTask.executeProcessorTask(DefaultReadTask.java:341) at com.sun.enterprise.web.connector.grizzly.DefaultReadTask.doTask(DefaultReadTask.java:263) at com.sun.enterprise.web.connector.grizzly.DefaultReadTask.doTask(DefaultReadTask.java:214) at com.sun.enterprise.web.connector.grizzly.TaskBase.run(TaskBase.java:265) at com.sun.enterprise.web.connector.grizzly.ssl.SSLWorkerThread.run(SSLWorkerThread.java:106)

接下来是:

PWC6344: Unable to create output writer for file /path/to/jsp/file/jsp_file.jsp.java|#]

有时只打印 PWC6344 错误，有时两者都打印，PWC1231 错误后面总是跟着 PWC6344(这有点道理，因为当 IOException 发生时会抛出该异常)。

好吧，这两次错误都发生了，我唯一做的就是停止并启动实例，一切都又好了，而且这个错误只发生在其中一台服务器上。

发生了什么事？...或者我如何诊断导致此问题的原因，以便我可以解决问题，而不是永远停止并重新开始...

更新:

我正在研究这可能是一个文件描述符问题，正如 sbridges 所建议的，但是!，文件处理程序的最大数量是 811975，一台服务器中打开了 4520 个文件，另一台服务器中打开了 359532 个文件，而只有 6894 个文件。

所以，我想可以肯定地说这不是问题!

有人有其他理论吗？

Answer 1

看起来权限设置不正确，无法将编译好的jsp页面写入​​磁盘，

/path/to/jsp/file/jsp_file.jsp.java (Permission denied) 

该目录/文件的权限是否正确？
