configuring ldap

[slag]

I'm trying to connect activiti 5.17.0 to my ldap server.

According to the documentation (http://www.activiti.org/userguide/) I need to modify activiti-standalone-context.xml.
This file is however not present in after version 5.16.4.


I added the following configuration to activiti-custom-context.xml.

  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource" />
        <property name="transactionManager" ref="transactionManager" />
        <property name="databaseSchemaUpdate" value="true" />
        <property name="jobExecutorActivate" value="true" />
        <property name="enableDatabaseEventLogging" value="true" />
        <property name="customFormTypes">
          <list>
            <bean class="org.activiti.explorer.form.UserFormType"/>
            <bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/>
            <bean class="org.activiti.explorer.form.MonthFormType"/>
          </list>
        </property>

      <property name="configurators">
          <list>
              <bean class="org.activiti.ldap.LDAPConfigurator">
                <!– Server connection params –>
                <property name="server" value="192.168.1.106" />
                <property name="port" value="389" />
                <property name="user" value="uid=admin,dc=newtec,dc=eu" />
                <property name="password" value="secret" />
                <!– Query params –>
                <property name="baseDn" value="ou=people,ou=intranet,dc=newtec,dc=eu" />
                <property name="queryUserByUserId" value="(&amp;(objectClass=inetOrgPerson)(uid={0}))" />
                <property name="queryUserByFullNameLike" value="(&amp;(objectClass=inetOrgPerson)(|({0}=*{1}*)({2}=*{3}*)))" />
                <property name="queryGroupsForUser" value="(&amp;(objectClass=groupOfNames)(Member={0}))" />
                <!– Attribute config –>
                <property name="userIdAttribute" value="uid" />
                <property name="userFirstNameAttribute" value="cn" />
                <property name="userLastNameAttribute" value="sn" />
                <property name="groupIdAttribute" value="cn" />
                <property name="groupNameAttribute" value="cn" />
             </bean>
          </list>
        </property>
  </bean>

and the following to activiti-ui-context.xml

  <bean name="explorerApp" class="org.activiti.explorer.ExplorerApp" scope="session">
    <property name="environment" value="${activiti.ui.environment}" />
    <property name="useJavascriptDiagram" value="${activiti.ui.jsdiagram}" />
    <property name="i18nManager" ref="i18nManager" />
    <property name="viewManager" ref="viewManager" />
    <property name="notificationManager" ref="notificationManager" />
    <property name="attachmentRendererManager" ref="attachmentRendererManager" />
    <property name="formPropertyRendererManager" ref="formPropertyRendererManager" />
    <property name="variableRendererManager" ref="variableRendererManager" />
    <property name="applicationMainWindow" ref="mainWindow" />
    <property name="componentFactories" ref="componentFactories" />
    <property name="workflowDefinitionConversionFactory" ref="workflowDefinitionConversionFactory" />
    <property name="loginHandler" ref="activitiLoginHandler" />
    <property name="simpleWorkflowJsonConverter" ref="simpleWorkflowJsonConverter" />
    <property name="adminGroups">
       <list>
         <value>admin</value>
       </list>
    </property>
    <property name="userGroups">

    </property>
  </bean>

At startup i get the following error in catalina.out which results in explorer not running.

When i remove the LDAP part from activiti-custom-context.xml it starts up normal.

Any help is welcome.

The exception is

org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.activiti.ldap.LDAPConfigurator] for bean with name 'org.activiti.ldap.LDAPConfigurator#de1e852' defined in class path resource [activiti-custom-context.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/activiti/engine/cfg/AbstractProcessEngineConfigurator

Are you mixing jars of Activiti? Seems like some part of your jars are of a later version than others.

[slag]

I double checked and i have the correct ldap connector installed.
Since B.Schnarr has the same issue, this also seens unlikely.
Could there be a wrong version on the maven repo?

[jbarrez]

I'm not sure if  B.Schnarr has the exact same issue. Are you using maven? Can you post your pom.xml?

[slag]

I am not compiling or changing code.
I did a fresh install and configured it to use ldap. I manually downloaded the ldap connector from the maven repo and placed it in the lib folder of activiti-explorer.
http://mvnrepository.com/artifact/org.activiti/activiti-ldap/5.17.0

[jbarrez]

Ok last resort then .. can you validate that in the activiti-engine.jar you have a class called AbstractProcessEngineConfigurator.class? If so, I'm officially puzzled by the stacktrace you're getting

[slag]

That classfile is in activiti-engine.jar
Is it possible i did something wrong with my configuration?
Would it be possible to update the documentation to reflect change to spring?
Should I restart installation and document my actions step by step so you can reproduce?
If you are interested i can create a Virtualbox machine with my configuration and share it with you.

[jbarrez]

A maven project would be most helpful to get it quickly up and running

[slag]

I don't understand why i should create a maven project and what i would have to do with it.
I copy paste a jar file in an activiti/tomcat folder.
I edit a text file with my ldap config.
I am not compiling 1 letter of code.

I do have the same problem slag mentioned with 5.17 version of activiti.

When i add the ldappart to activiti-custom-context.xml activiti crashes with the same exact error message as below.
SEVERE: Error listenerStart
May 12, 2015 1:18:00 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/activiti-explorer] startup failed due to previous errors

Do we go back to a version 5.16 or do we wait for 5.18.  Please let us know.

For me the same. I already opened another post concerning this. But without success: http://forums.activiti.org/content/configure-ldap-activiti-517
