topic Processing tld function in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/processing-tld-function/m-p/127420#M89640 <HTML><HEAD></HEAD><BODY><SPAN>I have an issue with how Alfresco handles processing associated tlds in Linux (Ubuntu Feisty Fawn). Under Windows, there is no problem, but when under Linux, an exception is thrown indicating that is unable to evaluate a function specified in the tld. Moreover, the string that it complains about has the namespace perpended to it. I'm thinking that this is because somewhere Alfresco parses this String incorrectly, assuming Windows semantics. And so when it should be the name of the function it evaluates, it evaluates the namespace perpended to the function and throws an exception.</SPAN><BR /><BR /><SPAN>Below is the stacktrace:</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>Stacktrace:<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:467)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:371)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:315)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<BR />&nbsp;&nbsp;&nbsp;org.apache.catalina.ssi.SSIFilter.doFilter(SSIFilter.java:125)<BR />&nbsp;&nbsp;&nbsp;org.alfresco.filter.CacheControlFilter.doFilter(CacheControlFilter.java:187)<BR /><BR />root cause<BR /><BR />javax.servlet.ServletException: javax.servlet.jsp.el.ELException: An error occurred while evaluating function "taglib:getLibTester"<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:842)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:779)<BR />&nbsp;&nbsp;&nbsp;org.apache.jsp.assets.includes.nav_jsp._jspService(nav_jsp.java:80)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:328)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:315)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<BR />&nbsp;&nbsp;&nbsp;org.apache.catalina.ssi.SSIFilter.doFilter(SSIFilter.java:125)<BR />&nbsp;&nbsp;&nbsp;org.alfresco.filter.CacheControlFilter.doFilter(CacheControlFilter.java:187)<BR /><BR />root cause<BR /><BR />java.lang.NullPointerException<BR />&nbsp;&nbsp;&nbsp;sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)<BR />&nbsp;&nbsp;&nbsp;sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)<BR />&nbsp;&nbsp;&nbsp;sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)<BR />&nbsp;&nbsp;&nbsp;java.lang.reflect.Method.invoke(Method.java:597)<BR />&nbsp;&nbsp;&nbsp;org.apache.commons.el.FunctionInvocation.evaluate(FunctionInvocation.java:172)<BR />&nbsp;&nbsp;&nbsp;org.apache.commons.el.ExpressionEvaluatorImpl.evaluate(ExpressionEvaluatorImpl.java:263)<BR />&nbsp;&nbsp;&nbsp;org.apache.commons.el.ExpressionEvaluatorImpl.evaluate(ExpressionEvaluatorImpl.java:190)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:929)<BR />&nbsp;&nbsp;&nbsp;org.apache.jsp.assets.includes.nav_jsp._jspService(nav_jsp.java:71)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:328)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:315)<BR />&nbsp;&nbsp;&nbsp;org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<BR />&nbsp;&nbsp;&nbsp;org.apache.catalina.ssi.SSIFilter.doFilter(SSIFilter.java:125)<BR />&nbsp;&nbsp;&nbsp;org.alfresco.filter.CacheControlFilter.doFilter(CacheControlFilter.java:187)<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><SPAN>Below is the jsp, tld, and java.
