    JBoss 3.0 beta doesn't deploy more than 64 entity beans

    Vladlen Rudenko Newbie

      Hi all. On your site appeared the link to JBoss beta with Tomcat. It it's very temptating to use, but at the same time JBoss engine has changed. I tried to deploy our application we had bean successfully developing many monthes with JBoss alpha version. I found out that betta's entity beans limit is 64. It is probably of some xml parser or something else. Anyway, I put the code that generates beans, use the constant there to set the beans number.
      Thanks in advance.

      Code:
      import java.io.*;
      public class M {
      public static void main(String[] arg) throws IOException {
      String pattern = "BEAN_NAME",
      ejbHead = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'><ejb-jar><enterprise-beans>",
      ejbEnd = "</enterprise-beans><assembly-descriptor/></ejb-jar>",
      ejbContent = "<ejb-name>BEAN_NAME</ejb-name><local-home>BEAN_NAMELocalHome</local-home>BEAN_NAMELocal<ejb-class>BEAN_NAMEBean</ejb-class><persistence-type>Bean</persistence-type><prim-key-class>java.lang.String</prim-key-class>False",
      jbossHead = "<?xml version=\"1.0\" encoding=\"Cp1251\"?>false<container-configurations/><resource-managers/><enterprise-beans>",
      jbossEnd = "</enterprise-beans>",
      jbossContent = "<ejb-name>BEAN_NAME</ejb-name><local-jndi-name>java/comp/env/ejb/BEAN_NAME</local-jndi-name><configuration-name></configuration-name>",
      home = "import javax.ejb.EJBLocalHome;import javax.ejb.EJBHome;import java.util.*;public interface BEAN_NAMELocalHome extends EJBLocalHome { public BEAN_NAMELocal create(java.lang.String key); public BEAN_NAMELocal findByPrimaryKey(java.lang.String key); }",
      remote = "import javax.ejb.EJBLocalObject; public interface BEAN_NAMELocal extends EJBLocalObject {}",
      bean = "import javax.ejb.EntityContext; import javax.ejb.EntityBean; public class BEAN_NAMEBean implements EntityBean { public java.lang.String ejbCreate(java.lang.String key) { return key; } public void ejbPostCreate(java.lang.String key) {} public void ejbRemove() {} public void ejbLoad() {} public void ejbStore() {} public java.lang.String ejbFindByPrimaryKey(java.lang.String key) { return key; } public void ejbActivate() {} public void ejbPassivate() {} public void ejbPostCreate() {} public void setEntityContext(EntityContext ec) {} public void unsetEntityContext() {} }";

      int MAX_BEANS = 70;
      java.util.regex.Pattern p = java.util.regex.Pattern.compile(pattern);
      java.util.regex.Matcher m;
      File dir = new File("src/"); dir.mkdirs();
      FileWriter ejb = new FileWriter("src/" + "ejb-jar.xml"),
      jboss = new FileWriter("src/" + "jboss.xml");


      ejb.write(ejbHead); jboss.write(jbossHead);
      for(int i=0; i<MAX_BEANS; i++) {
      String beanName = "Bean" + i;
      m = p.matcher(ejbContent); ejb.write(m.replaceAll(beanName));
      m = p.matcher(jbossContent); jboss.write(m.replaceAll(beanName));
      FileWriter homeFW = new FileWriter("src/" + beanName + "LocalHome.java");
      FileWriter remoteFW = new FileWriter("src/" + beanName + "Local.java");
      FileWriter beanFW = new FileWriter("src/" + beanName + "Bean.java");
      m = p.matcher(home); homeFW.write(m.replaceAll(beanName)); homeFW.close();
      m = p.matcher(remote); remoteFW.write(m.replaceAll(beanName)); remoteFW.close();
      m = p.matcher(bean); beanFW.write(m.replaceAll(beanName)); beanFW.close();
      }

      ejb.write(ejbEnd); jboss.write(jbossEnd);
      ejb.close(); jboss.close();
      }
      }

          Hi,

          I've not had time to test this myself.
          What error are you getting in log/server.log

          This will be a useful addtion to the testsuite,
          say about 1000 beans :-)

          64 is a suspicous number 2^6?

          Regards,
          Adrian

              Vladlen Rudenko Newbie

              This is the jar with 70 entity beans, generated by prev. code. It doesn't deploy on my comp, Win2K, 0.5Gb, JBoss beta with Tomcat,
              Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b65)
              Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)

                That's very weird.

                I'll have to try this with beta2. The error is in
                the jsr77 processing of org.jboss.ejb.Application.

                Application doesn't exist anymore in beta2 it is
                replaced with EjbModule.
                The jsr77 has also been reworked
                But that doesn't really explain the error I can here?

                Regards,
                Adrian

                  I think your problem is java1.4

                  There is a bug in jmxri.jar that causes problems with
                  java 1.4

                  I've tried your jar with latest CVS and it works fine.
                  Latest CVS uses JBossMX instead of jmxri.jar which
                  doesn't have this bug.
