  1. POHow to dynamically pass parameters in web.xml using weblogic 10.3.x?
    text
    copied!<p>I am trying to pass a JVM parameter for a variable configured in web.xml as a context-parameter using a -D notation when starting weblogic server. I have already tried this same configuration using Tomcat 7 and it works as expected, but it DOES NOT work in weblogic server 10.3.3. Any clues?</p> <p><strong>web.xml</strong></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"&gt; &lt;display-name&gt;testeParWebXml&lt;/display-name&gt; &lt;context-param&gt; &lt;description&gt;Habilita ou desabilita a configuração de debug do Facelets! Página de debug do Seam.&lt;/description&gt; &lt;param-name&gt;facelets.DEVELOPMENT&lt;/param-name&gt; &lt;param-value&gt;${habilitar.debug}&lt;/param-value&gt; &lt;/context-param&gt; &lt;welcome-file-list&gt; </code></pre> <p>Then when starting the jvm I pass the parameter using: </p> <pre><code>-Dhabilitar.debug=true </code></pre> <p>And I built a Servlet to test: </p> <pre><code>protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter pw = response.getWriter(); String valorParametro = getServletContext().getInitParameter("facelets.DEVELOPMENT"); pw.write("Param value from web.xml ==&gt;&gt; " + valorParametro); } </code></pre> <p>As I mentioned using Tomcat if I change the value to false or true in the -Dhabilitar.debug flag it correctly prints the value in the servlet.</p> <pre><code>Param value from web.xml ==&gt;&gt; true </code></pre> <p>In weblogic I get the output like:</p> <pre><code>Param value from web.xml ==&gt;&gt; ${habilitar.debug} </code></pre> <p>As noticed weblogic DOES NOT parse the value of the variable set in web.xml.</p> <p>Is it possible to make this work properly in weblogic 10.3.3?</p>
