我正在从源代码编译openfire并正确编译。但它在访问Web插件时会导致问题。 错误：
org.apache.jasper.JasperException: Unable to compile class for JSP

at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:349)

由
引起java.lang.NullPointerException at org.apache.jasper.JspCompilationContext.getTldResourcePath(JspCompilationContext.java:530)
at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:410)
