Hi all,
I am working with jboss3.0.6-Tomcat4.1.18, in a windows 2000 P4 2.4Ghz 1Gb Ram,
I am doing some stress to a jsp that calls an EJB method, the jsp looks like:
| <%@ page import="es.myPackage.*"%>
| <%
|
| try {
|
| javax.naming.InitialContext ctx = new javax.naming.InitialContext();
| ConstantHome constantHome = (ConstantHome)ctx.lookup("es.myPackage.Constant");
| Constant constant = constantHome.create();
| java.util.Hashtable ht = (java.util.Hashtable)constant.findAll();
|
| } catch (Exception ignoreThis) {}
|
| %>
The Constant EJB Class looks like:
| package es.myPackage;
|
| public class ConstantBean implements javax.ejb.SessionBean {
|
| private javax.ejb.SessionContext context;
| private java.sql.Connection con = null;
|
| public void setSessionContext(javax.ejb.SessionContext aContext) {
| this.context=aContext;
| }
|
| public void ejbActivate() { }
| public void ejbPassivate() { }
| public void ejbRemove() { }
| public void ejbCreate() { }
|
| public java.util.Hashtable findAll() throws java.sql.SQLException {
| java.util.Hashtable ht = new java.util.Hashtable();
| try {
|
| ht.put("lunes", "monday");
| ht.put("martes", "tuesday");
| ht.put("miercoles", "wednesday");
|
| } catch(Exception e){ System.out.print(e); }
|
| return ht;
| }
|
| }
My tomcat41-service.xml config is:
| [...]
| <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
| port="38080" minProcessors="5" maxProcessors="200"
| enableLookups="false" redirectPort="38443"
| acceptCount="150" debug="0" connectionTimeout="-1"
| useURIValidationHack="false" disableUploadTimeout="true" />
| [...]
I execute jboss with the "-Xms50m -Xmx900m" memory options.
I stress the server with a run test of 1 minute, from 1 to 120 users. The server pass
the stress test, but when trying to compile other
application Jsps, the server falls in a:

The application at production must not fall with 120 users... And I dont believe jboss
cannot resists this simple EJB test.
Any ideas of whats wrong ?
