  1. POGWT + JSTL in development mode -- is it possible?
    text
    copied!<p>I have a GWT app (generated by roo) that I have decided to secure with Spring Security. Roo generates a login.jspx page as part of the security setup and this jspx uses some basic JSTL taglibs.</p> <p>When running in development mode, the underpinning Jetty server apparently does not like this. With the following Maven dependencies</p> <pre><code> &lt;dependency&gt; &lt;groupId&gt;javax.servlet.jsp.jstl&lt;/groupId&gt; &lt;artifactId&gt;jstl-api&lt;/artifactId&gt; &lt;version&gt;1.2&lt;/version&gt; &lt;classifier/&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.glassfish.web&lt;/groupId&gt; &lt;artifactId&gt;jstl-impl&lt;/artifactId&gt; &lt;version&gt;1.2&lt;/version&gt; &lt;classifier/&gt; &lt;/dependency&gt; </code></pre> <p>I get</p> <pre><code>java.lang.AbstractMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext; </code></pre> <p>My guess was that the jstl-impl dependency was conflicting with one already provided by the web container, but when I change its scope to provided, I get:</p> <pre><code>org.apache.jasper.JasperException: /WEB-INF/views/login.jspx(22,69) The attribute prefix fn does not correspond to any imported tag library </code></pre> <p>Anybody gotten this to work successfully?</p> <p>P.S. I hear rumors that you can just export the app to Tomcat, and it runs fine, but GWT compilation can be a time consuming operation, so it would be great to get this working in dev mode.</p>
