I am having a problem using expression language and struts tags together in a struts2 project. The following code snippet from a jsp file illustrates my problem. The fruits object is passed by a servlet. I know that the error is not from the servlet because when I comment out the form code, it correctly prints out each fruit. <c:forEach...

I'm creating a custom taglib with .tag files. Everything works great, except when I load 2 pages at the same time. It seems the .tag files are re-compiled on every request and the concurrency causes the compilation to fail. Is this normal behavior for .tag files? I would have expected them to be compiled only once. Is there some way t...
We just upgraded Tomcat and the newer Tomcat doesn't like nested quotes in the tag, so we have to alternate between single and double quotes. For example, We used to have, <form id="search" action="<fmt:message key="search.url"/>"> Now we can change it to, <form id="search" action="<fmt:message key='search.url'/>"> What should I d...
Currently my jsp 2.0 tags that need spring beans use this code: ac = WebApplicationContextUtils.getWebApplicationContext( servletContext); ac.getBeansOfType(MyRequestedClass.class); The I just get the first matching bean. This code works fine, but has the undesired drawback that I spend about half my page rendering time looking up sp...

I work with a front-end developer who writes JSP files. We have a form that is working correctly, except validation/binding/processing errors can't seem to be displayed with Spring's <form:errors/> tag. I've confirmed that the error is being set, and what is apparently the correct path for the errors. Supposedly <form:errors path="*" /...
I consistently have troubles getting my TagExtraInfo implementations to work properly. I have one implementation that works, and one that doesn't and I unable to see the difference between the two. And all the IDE's seem to have have "bugs/features" regarding this, which makes it hard to see where the problem actually is. The relationsh...

What is the equivalent "servlet code" for this: <jsp:useBean id="user" class="beans.UserBean" scope="session"/> <jsp:setProperty name="user" property="*"/> Tomcat translates this to: beans.UserBean user = null; synchronized (session) { user = (beans.UserBean) _jspx_page_context.getAttribute("user", PageContext.SESSION_SCOPE); ...
Suppose I have a custom tag that takes a List of Strings: <%@ attribute name="thelist" type="java.util.List<java.lang.String>" required="true" %> How can I create this attribute in the jsp that calls the tag? I could use a scriptlet <tags:list thelist='<%= java.util.Arrays.asList("blah","blah2") %>' /> but is there any wa...

I have a requirement where in the JSP page itself is created by the user and stored in the database. When viewing results we need to render this JSP to the client, evaluating all tags inside this JSP. I am aware that it is doable as OpenCMS and Blogger both implement this functionality. But, I just can't find the right way. Any pointer...
