Activit without Spring

[omni_ok]

Can someone help me on following points?

1. I need to implement Activiti without Spring. I want to use simple Servet-JSP code. However, I could not find much help on this.

2. Using simple Servlet-JSP code, I am getting the following exception related to slf4j

Failed to instantiate SLF4J LoggerFactory

3. Last point : Configuring MYSQL database. I have put the MYSQL jar files in web-app/lib of my application and configured the db.properties file. Also the new MYSQL JDBC connection is mentioned in my code. However,  I cannot proceed without the resolving the above exception. How do I verify if MYSQL is configured correctly with Activiti.

Thank you in advance !!!

Hi

1. I need to implement Activiti without Spring. I want to use simple Servet-JSP code. However, I could not find much help on this.

Activiti engine does not depend on spring (only spring beans as you can see).

How to get it running: Create ProcessEngineConfiguration and build process engine from it.

2. Using simple Servlet-JSP code, I am getting the following exception related to slf4j

libraries in the classpath are missing

[INFO] +- org.slf4j:slf4j-api:jar:1.7.2:compile
[INFO] +- org.slf4j:jcl-over-slf4j:jar:1.7.2:compile


3. Last point :

try and post exception.

Regards
Martin

[omni_ok]

Thanks we could proceed with your suggestion.
I use "ibatis-sqlmap-3.0-beta-10.jar" and get the following exception:
   java.lang.ClassCastException: org.apache.ibatis.logging.slf4j.Slf4jImpl cannot be cast to org.apache.ibatis.logging.Log

I also tried using "mybatis-3.0.4.jar", but had some other exception.

[martin_grofcik]

activiti-egine dependency is org.mybatis:mybatis:jar:3.2.2:compile. Did you try this one?

[omni_ok]

Yes Thanks Martin. It worked. However, the MYSQL exception still persists.
I have mentioned the following code:

ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()                                  .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)                                  .setJdbcUrl("jdbc:mysql://localhost:3306/activiti?autoReconnect=true&user=root&password=root")                                  .setJobExecutorActivate(true) .buildProcessEngine();


The exception here is :
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ''@'localhost' to database 'activiti'

However, when I write the same jdbc connection URL in a standalone Java program, it works!
The db.properties file (placed in "apache-tomcat-6.0.26\webapps\activiti-explorer.war\WEB-INF\classes") is alsoconfigured to MYSQL database.

[martin_grofcik]

Hi,

Access denied for user

for me it seems like my SQL configuration issue.

Regards
Martin

[omni_ok]

I have done with with MYSQL connection now. I just changed the above code to the following:

ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()                             .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)                             .setJdbcUrl("jdbc:mysql://localhost:3306/activiti").setJdbcPassword("root").setJdbcUsername("root")                             .setJobExecutorActivate(true).buildProcessEngine();

However, I am getting a new exception.
The code written is:

RepositoryService repositoryService =processEngine.getRepositoryService();
RuntimeService runtimeService =processEngine.getRuntimeService();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("vacationRequest");

For this code the exception is:

Please help on this!

[martin_grofcik]

the issue is on your process definition. (form property type user is not supported)

[omni_ok]

The process definition is "vacationRequest" which is provided in Activiti 5.14 by default. I have not created this process definition. I want to check, how can we invoke a process from a simple Servlet-JSP application.

[martin_grofcik]

vacationRequest uses form types which are configured in activiti-explorer. Your configuration does not support these form types.
Try simple process start->userTask->end
