1、问题：org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.pvm.internal.model.ExecutionImpl#1]
�q�接Mysql5�Ӟ��jBPM4�q�行�?End�l�点时的错误�Q�把 hibernate.dialect 改�ؓ org.hibernate.dialect.MySQLInnoDBDialect

2、问题：org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.pvm.internal.type.variable.UnpersistableVariable is not a: org.jbpm.pvm.internal.type.Variable

In case you still got the problem. I also had this error due to the fact the Object I was adding as a variable was not Serializable.

Implementing java.io.Serializable should fix this error.

意思是压入上下文的对象要实�?Serializable接口

3、问题：Caused by: java.lang.ClassNotFoundException: de.odysseus.el.util.SimpleResolver

Requirements

JUEL requires Java 5 or later.

加入juel.jar

-------------------------
I think I get same problem when trying to integrate JBPM4 into my app. And I find out why.
Because you're using Tomcat 6.0... The lib el-api.jar in %tomcat_home%/lib conflicts with juel.jar, which exists in %jbpm4_home%/lib.

juel: You will find the 2 jars define the same api for javax/el/ExressionFactory.

The solution is that you use Tomcat 5.5 instead of Tomcat 6.0. Because tomcat 5.5 uses commons-el.jar (Tomcat5.5/common/lib)

Or you can still use Tomcat 6.0, but you must replace el-api.jar with juel.jar. And don't forget to remove juel.jar from your app lib(A duplicate import, if you don't remove).

Try it!

1. 下蝲最新版本的 JBoss jBPM Starters kit。解压这个文�Ӟ��假设解压目录�? "${jbpm.starters.kit}"�Q�它的下面应该有 jbpm�Q? jbpm-bpel�Q�jbpm-db�Q�jbpm-designer�Q�jbpm-server 五个子目录。其中我们要用到的是 jbpm �? jbpm-db两个目录�?/p>

2. ��D��?jbpm-db 子目录。在该目录下可以扑ֈ� build.properties 文�g。这个文仉��要作一定修�Ҏ��能��用�?扑ֈ�下面的这�D�代码：

     jbpm.3.location=C:/jbpm-X.X
     upgrade.hibernate.properties=hsqldb/hibernate.properties
     upgrade.libdir=hsqldb/lib
     upgrade.old.schema.script=hsqldb/upgrade.scripts/hsqldb.create.jbpm.3.0.2.sql

注意�W�一行，��?“C:/jbpm-x.x” �Ҏ�� "${jbpm.starters.kit}/jbpm"�?/p>

3. ��D��?nbsp;jbpm 子目录。在 jbpm"src"config.files 路径下可以找�?hibernate.cfg.xml 文�g。这个文仉��要修改和数据库连接相关的部分。找��C��面这行代码：

<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect>
<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver>
<property name="hibernate.connection.url">jdbc:hsqldb:mem:.;sql.enforce_strict_size=true>
<property name="hibernate.connection.username">sa>
<property name="hibernate.connection.password">property>

��其修改�?Oracle 的格式：

<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialectproperty>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver>
<property name="hibernate.connection.url">jdbc:oracle:thin@localhost:1521:fred>
<property name="hibernate.connection.username">FiberSchedulerJBPM>
<property name="hibernate.connection.password">FiberSchedulerJBPM>

��D��到子目录 jbpm 下的路径 jbpm-db"oracle"lib�Q�下载最新的 Oracle jdbc驱动�E�序�Q�我使用的是 class14.jar�Q�，把它攑֜�该�\径下�?br /> 其中 "localhost" 换成你自��q��数据库所在的机器名（或者ip地址�Q�，"fred" 换成你自��q��Oracle数据库的 SID 名字�Q?使用你自��q�� Oracle 数据库用户名和密码来替换 "FiberSchedulerJBPM" �?br /> 4. ��D��?jbpm-db 子目录，�?jbpm-db"oracle 路径下找到文�?hibernate.properties。找��C��面这�D�代码：

hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
hibernate.connection.url=jdbc:oracle:thin@HOST:PORT:SID
hibernate.connection.username=USER
hibernate.connection.password=PASSWORD

�Ҏ��你的数据库配�|�修改，我的修改如下�Q?br />

   hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
   hibernate.connection.url=jdbc:oracle:thin:@localhost:1521:fred
   hibernate.connection.username=FiberSchedulerJBPM
   hibernate.connection.password=FiberSchedulerJBPM

5. 在目�?nbsp; jbpm-db下找到ant脚本 build.xml 文�g�Q�这个ant 脚本中有�q�样一�D�代码是用来生成数据库脚本的�Q?br />

<target name="db.scripts" description="helper target to generate the database scripts" depends="prepare">
    <delete dir="build/${db}/scripts" />
<mkdir dir="build/${db}/scripts" />
<java classname="org.jbpm.db.JbpmSchema" fork="true">
    <classpath refid="classpath.${db}" />
    <arg value="scripts"/>
    <arg value="${basedir}/build/${db}/scripts"/>
    <arg value="${db}"/>
     <arg value="${jbpm.3.location}/src/config.files/hibernate.cfg.xml"/>
     <arg value="${basedir}/${db}/hibernate.properties"/>
   java>
target>

�q�段脚本��调�?jBPM的类 org.jbpm.db.JbpmSchema.java �?main �Ҏ��Q��ƈ�l�他�?个参数。我们在目录 jbpm 的�\�U?jbpm"src"java.jbpm"org"jbpm"db 下找到类 JbpmSchema�Q�打开它找到这么一�D�代码：

public static void main(String[] args) {
   try {
     if ( (args==null) || (args.length==0) ) {
       throw new IllegalArgumentException();
     }

     String cmd = args[0];

     if ("create".equalsIgnoreCase(cmd)) {
       Configuration configuration = createConfiguration(args, 1);
       new JbpmSchema(configuration).createSchema();
     } else if ("drop".equalsIgnoreCase(cmd)) {
       Configuration configuration = createConfiguration(args, 1);
       new JbpmSchema(configuration).dropSchema();
     } else if ("clean".equalsIgnoreCase(cmd)) {
       Configuration configuration = createConfiguration(args, 1);
       new JbpmSchema(configuration).cleanSchema();
     } else if ("scripts".equalsIgnoreCase(cmd)) {
       Configuration configuration = createConfiguration(args, 3);
       new JbpmSchema(configuration).saveSqlScripts(args[1], args[2]);
     }

昄��Q�它只��用了ant脚本传给它的前三个参数。当生成非基�?Oracle 的数据库脚本�Ӟ��前三个脚本��够了。问题是当生成基�?Oracle 的数据库脚本�Ӟ��需要��用后两个参数。所以，我们在这�D�代码的后面加上�Q?br />

    else if ((args != null) && (args.length > 3) && ("scripts".equalsIgnoreCase(cmd))) {
           new JbpmSchema(JbpmSessionFactory.createConfiguration()).saveSqlScripts(args[1], args[2]);
         }

现在�q�段代码应该是这个样子：

    public static void main(String[] args) {
      try {
        if ( (args==null) || (args.length==0) ) {
          throw new IllegalArgumentException();
        }

        String cmd = args[0];

        if ("create".equalsIgnoreCase(cmd)) {
         Configuration configuration = createConfiguration(args, 1);
         new JbpmSchema(configuration).createSchema();
       } else if ("drop".equalsIgnoreCase(cmd)) {
         Configuration configuration = createConfiguration(args, 1);
         new JbpmSchema(configuration).dropSchema();
       } else if ("clean".equalsIgnoreCase(cmd)) {
         Configuration configuration = createConfiguration(args, 1);
         new JbpmSchema(configuration).cleanSchema();
       } else if ("scripts".equalsIgnoreCase(cmd)) {
         Configuration configuration = createConfiguration(args, 3);
         new JbpmSchema(configuration).saveSqlScripts(args[1], args[2]);
       } else if ((args != null) && (args.length > 3) && ("scripts".equalsIgnoreCase(cmd))) {
         new JbpmSchema(JbpmSessionFactory.createConfiguration()).saveSqlScripts(args[1], args[2]);
       }

好了�Q�现在一切都完美了。我们接下来执行最后一步，生成我们需要的脚本�?/p>

6. 打开命��o行提�C�符�H�口�q�在命��o行中��D��到子目录 jbpm-db�Q�键入命�?nbsp; ant oracle.scripts。等命��o执行完毕以后�Q�会发现在�\�?jbpm-db"build"oracle"scripts 下生成了我们需要的脚本文�g�Q?br /> oracle.clean.sql
oracle.create.sql
oracle.drop.create.sql
oracle.drop.sql
