Workflow getting paused at Auto process activity

Hi,

We are facing problem with our back up servers with the wokflow. Back up server has replicated code from Prodcution server and everything runs fine on productions server.

Same workflow when executed on backup server gets paused when it reaches the Auto process activity.

Below are the error logs that we are getting:

server.log:

Itext jar was not accessible to sever because the user did not have rights to get access to it. After providing the permission right the workflow started working fine.

DoMethod]] - Servlet.service() for servlet DoMethod threw exceptionjava.lang.NoClassDefFoundError: com/lowagie/text/DocumentException at com.documentum.custom.library.AutoProcessCR.<init>(AutoProcessCR.java:80)

This error indicates that you are using lowagie(Apache POI may be) library in your custom java method code and method server is unable to locate the required jar. So in result unable to execute your method.

Make sure that you copied your required libraries to the java_mthod folder in method server.

Paste supporting libraries along with your custom code classes.

Hope it helps.

All the supporting jar files are in place and have even defined in classpath

Alvaro_de_Andres

If you are using modules to deploy your custom activity you have to pack those libraries with the modules, otherwise you need to put the jar files in the jboss lib folder (just to be sure you should deploy them into the DoMethod\WEB-INF\lib).

Julien.Fontaine

Did you also copy all the related jar file in classpath of the Server Method ?
