Hi, We are currently stress-testing a struts-based application. We are using JBoss 3.2.3 (with integrated tomcat) on a 2-processor Dell with 1 Gig of RAM. We use struts v1.1.
The application just runs fine until we get to around 100 concurrent users. From that point on, we get a "java.lang.IllegalArgumentException: No bean specified" exception (reduced stack trace below). Other mails about this subject almost always talk about omitted beans in JSP's or malconfigured struts-config.xml files. However, these 100 users are "automated" (it's a program) and all performing the same scenario. It runs fine with 50 users so I don't suspect any problems in the struts-config.xml file. Does anyone have a suggestion? Thanks in advance, Tom Vekemans 2004-05-05 16:20:28,709 DEBUG [org.apache.struts.util.RequestUtils] Creating new ActionForm instance of type 'be.mil.cccis.bcc17.fact17.web.invoice.DisplaySavedInvoiceFormBean' 2004-05-05 16:20:28,709 DEBUG [org.apache.struts.util.RequestUtils] --> [EMAIL PROTECTED] 2004-05-05 16:20:28,709 DEBUG [org.apache.struts.action.RequestProcessor] Storing ActionForm bean instance in scope 'session' under attribute key 'displaySavedInvoiceForm' 2004-05-05 16:20:28,709 DEBUG [org.apache.struts.action.RequestProcessor] Populating bean properties from this request 2004-05-05 16:20:28,709 ERROR [org.jboss.web.localhost.Engine] StandardWrapperValve[action]: Servlet.service() for servlet action threw exception javax.servlet.ServletException: BeanUtils.populate at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1098) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:816) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1420) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:502) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) [...other tomcat-related stuff] at java.lang.Thread.run(Thread.java:534) 2004-05-05 16:20:28,709 DEBUG [org.apache.struts.action.RequestProcessor] processForwardConfig(ForwardConfig[name=next,path=/protected/invoice/budgetize_invoice.jsp,redirect=false,contextRelative=false]) 2004-05-05 16:20:28,756 ERROR [org.jboss.web.localhost.Engine] ----- Root Cause ----- java.lang.IllegalArgumentException: No bean specified at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUtils.java:837) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:934) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1096) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:816) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1420) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:502) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) [...other tomcat-related stuff] at java.lang.Thread.run(Thread.java:534)
