Unable to do bean instance creation

[jaikrishna]

I am getting the following error :


org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineConfiguration' defined in class path resource [activiti.cfg.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/activiti/image/ProcessDiagramGenerator

I dont know how to resolve this . I am not finding the right jar file containing the above class ..

[vasile_dirla]

find that line into the activiti code: ProcessEngineConfigurationImpl.java
<code>
Configuration configuration = initMybatisConfiguration(environment, reader, properties);
</code>
and inspect the "reader" , it seems the related input stream could not be read for some reason.

it should point to this file: org/activiti/db/mapping/mappings.xml

did you delete/change something or is a default deployment?

[jaikrishna]

I am not able to find that line at all . I dont have a file named ProcessEngineConfigurationImpl.java actually .. I have a book named Activiti 5.x Business Process Management Beginner's Guide [Kindle Edition]
Dr. Zakir Laliwala (Author), Irshad Mansuri ..
I was trying to follow example given in page no :21 ..

What's your Activiti version?

[jaikrishna]

Activiti 5.17.0

[vasile_dirla]

do you have a class: org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl ?

according to the stacktrace you posted you should have it:
<code>
   at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.initMybatisConfiguration(ProcessEngineConfigurationImpl.java:720)
at org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl.initSqlSessionFactory(ProcessEngineConfigurationImpl.java:708)
</code>

Where can I check such class org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl  is present or not .. Please guide me ..
I am new to activiti ..I am using eclipse …

Hi ,

The class which you were in telling is in jar file activiti 5.17 .. How can I check what value reader is getting ..
Please help me

[vasile_dirla]

download the activiti sources, config your IDE to use these sources for the activiti jar and then use the debugger in order to inspect the values.

try googleing "debugging with eclipse"
