EnumerationattributeNames = servletContext.getAttributeNames(); while (attributeNames.hasMoreElements()) { String attributeName = attributeNames.nextElement(); Object attributeValue = servletContext.getAttribute(attributeName); // Perform certain operations based on attributeName and attributeValue }
ServletContext context = getServletContext(); EnumerationIn this example, we again obtain an enumeration of all attribute names using the getAttributeNames method. This time, we filter the attribute names by only processing those that start with "myapp.". For these attributes, we obtain their corresponding value using the getAttribute method and perform certain operations based on the attribute name and value. The javax.servlet.ServletContext class is part of the Java Servlet API, which is typically included in a servlet container such as Apache Tomcat.attributeNames = context.getAttributeNames(); while (attributeNames.hasMoreElements()) { String attributeName = attributeNames.nextElement(); if (attributeName.startsWith("myapp.")) { Object attributeValue = context.getAttribute(attributeName); // Perform certain operations based on attributeName and attributeValue } }
