    text
    copied!<p>I want to generate a '<strong>back to search result</strong>' url in a JSP. I use JSTL taglib and it works:</p> <pre><code>&lt;c:url var="backUrl" value="list.html"&gt; &lt;c:forEach items="${param}" var="currentParam"&gt; &lt;c:param name="${currentParam.key}" value="${currentParam.value}"/&gt; &lt;/c:forEach&gt; &lt;/c:url&gt; &lt;a href="${backUrl}"&gt;&amp;lt; return to search results / list&lt;/a&gt; </code></pre> <p>I want to have a better solution, like a custom lib to generate the back link with one line code, by example:</p> <pre><code>&lt;tagname:url var="backUrl" value="list.html" includeAllParams="true" excludeParams="id, question"/&gt; &lt;a href="${backUrl}"&gt;&amp;lt; return to search results / list&lt;/a&gt; </code></pre> <p>Because, I want to re-use this code with an exclude param:</p> <pre><code>&lt;c:url var="backUrl" value="list.html"&gt; &lt;c:forEach items="${param}" var="currentParam"&gt; &lt;c:if test="${currentParam.key ne 'id'}"&gt; &lt;c:param name="${currentParam.key}" value="${currentParam.value}"/&gt; &lt;/c:if&gt; &lt;/c:forEach&gt; &lt;/c:url&gt; &lt;a href="${backUrl}"&gt;&amp;lt; return to search results / list&lt;/a&gt; </code></pre> <p>My question is what is the best practice and how can I create a custom lib to generate link by one line:</p> <pre><code>&lt;tagname:url var="backUrl" value="list.html" includeAllParams="true" excludeParams="id, question"/&gt; </code></pre> <p>Thank you.</p>
