我尝试编写一个应用程序,它可以从Web服务器(ipa文件)下载应用程序并安装它.有谁知道如何安装这个ipa文件?我可以使用应用程序内部的OTA或使用命令行来安装它吗?
在我使用spring security的应用程序中,我需要迭代返回的权限
<sec:authentication property="authorities"/>

所以我这样做:
<c:forEach var="auth" items="${'<sec:authentication property="authorities"/>'}" >
<h3> Each- <c:out value="${auth.authority }"></c:out> </h3><br />
</c:forEach>

但它不起作用.这是控制台中的错误:
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/portal] threw exception [Request processing failed; nested exception is org.apache.tiles.impl.CannotRenderException: ServletException including path '/WEB-INF/views/layouts/standard.jsp'.] with root cause org.apache.jasper.JasperException: /WEB-INF/views/resman/about/about.jsp (line: 40, column: 85) equal symbol expected
