    copied!<p>I'm currently researching OSGi with Spring, and working through a couple of examples from <a href="http://rads.stackoverflow.com/amzn/click/1430216123" rel="nofollow noreferrer">Pro Spring Dynamic Modules for OSGi</a>.</p> <p>My example web-app has a single controller like:</p> <pre><code>@Controller public class HelloWorldController { private HelloWorldService helloWorldService; @RequestMapping(method = RequestMethod.GET) @ModelAttribute("helloworld") public HelloWorld home() { return this.helloWorldService.find(); } // injected in - spring looks up the service from OSGi public void setHelloWorldService(HelloWorldService helloWorldService) { this.helloWorldService = helloWorldService; } } </code></pre> <p>The view resolver is configured as:</p> <pre><code>&lt;bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"&gt; &lt;property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/&gt; &lt;property name="prefix" value="/jsp/" /&gt; &lt;property name="suffix" value=".jsp" /&gt; &lt;/bean&gt; </code></pre> <p>Calling on the url <code>'http://localhost:8080/helloworld-web/spring/home'</code> should cause the view <code>jsp/home.jsp</code> to be rendered, with <code>helloworld</code> containing a single bean:</p> <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt; &lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;Spring DM HelloWorld&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;p&gt;Results from accessing Spring-DM service bundle:&lt;/p&gt; &lt;p&gt;Message &lt;c:out value="${helloworld.message}" /&gt;&lt;/p&gt; &lt;p&gt;Current Time: &lt;c:out value="${helloworld.currentTime}" /&gt;&lt;/p&gt; &lt;p&gt;Model Version: &lt;c:out value="${helloworld.modelVersion}" /&gt;&lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>However, I am seeing the following stacktrace:</p> <pre><code>org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51) org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409) org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:116) org.apache.jasper.compiler.TagLibraryInfoImpl.generateTLDLocation(TagLibraryInfoImpl.java:317) org.apache.jasper.compiler.TagLibraryInfoImpl.&lt;init&gt;(TagLibraryInfoImpl.java:148) org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:424) org.apache.jasper.compiler.Parser.parseDirective(Parser.java:493) org.apache.jasper.compiler.Parser.parseElements(Parser.java:1557) org.apache.jasper.compiler.Parser.parse(Parser.java:127) org.apache.jasper.compiler.ParserController.doParse(ParserController.java:212) org.apache.jasper.compiler.ParserController.parse(ParserController.java:101) org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:156) org.apache.jasper.compiler.Compiler.compile(Compiler.java:296) org.apache.jasper.compiler.Compiler.compile(Compiler.java:277) org.apache.jasper.compiler.Compiler.compile(Compiler.java:265) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:564) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:299) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:315) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:236) org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:257) org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1183) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:902) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) javax.servlet.http.HttpServlet.service(HttpServlet.java:690) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) </code></pre> <p>Because this is a WAR deployed as an OSGi bundle, its <code>WEB-INF/lib</code> directory is completely empty. </p> <p>My understanding was that the OSGi version of jasper would look for taglib descriptors and JARs outside of the individual web-app?</p> <p>Has anyone else seen this?</p>
