Examples with PageContext javax.servlet.jsp.PageContext used on opensource projects

Example 1 with PageContext

use of javax.servlet.jsp.PageContext in project tomcat by apache.

the class ScopedAttributeELResolver method setValue.

@Override
public void setValue(ELContext context, Object base, Object property, Object value) {
    Objects.requireNonNull(context);
    if (base == null) {
        context.setPropertyResolved(base, property);
        if (property != null) {
            String key = property.toString();
            PageContext page = (PageContext) context.getContext(JspContext.class);
            int scope = page.getAttributesScope(key);
            if (scope != 0) {
                page.setAttribute(key, value, scope);
            } else {
                page.setAttribute(key, value);
            }
        }
    }
}

Example 2 with PageContext

use of javax.servlet.jsp.PageContext in project tomcat by apache.
