Source for Explorer

I am trying to get the source for Explorer to look at it, learn and possibly reuse.I have tried the location https://svn.codehaus.org/activiti using subversive but I keep getting an error.!ENTRY org.eclipse.team.svn.core.svnnature 4 0 2013-03-27 10:52:26.766!MESSAGE SVN: '0x00000019: Check Out' oper

Subversion is not used anymore, go to https://github.com/Activiti

I don't want all of activiti anyway, just explorer.

Java/Activiti noob so any help would be appreciated.

Not only github has the sources of activiti explorer;-)

If you use the last releases (5.11, 5.12) the sources are placed as jar file in release bundle. download it and change to <activiti-5.11>\libs folder

Ahhh…you are correct. I have unzipped the source and I have tried a number of ways to import into a project in Eclipse. This is where my Eclipse lack of knowledge comes in. I have succeeded in importing the sources into my src folder but I am getting 9,000 or so errors because of dependencies.

How to fix the dependencies? I looked for a pom.xml file thinking I could use maven but no joy…

if you need the activiti explorer sources only for debbuging, the quick way would be to assign that sources jar to activiti-explorer.jar (in eclipse it is possible - select the needed jar, that needs sources, and call context menu and assign the jar with sources)

if you need the fixing-forking of activiti explorer, the following way may be used:
unpack the activiti explorer sources jar
the activiti bundle has the war.files - activiti explorer.war. Unpack it and use the libraries from /WEB-INF/lib directory in your activiti explorer project.
If you want to start A.E in Eclipse you must have in eclipse project all directories/js-scripts/vaadin css-s.
p.s i not used the maven project but i use the information from pom-xml;-)
i used the information from github to related to activiti explorer and activiti explorer web application

Duh….. ops:
"A.E" = Activiti Explorer

Thanks for your help. I now have it set up and can export a WAR. Next is getting it running in an Eclipse server instance.

Really enjoying learning Activity. Much better than Bonita (IMHO)

Care to explain why? I don't know a lot about Bonita, but the overall impression I get is fairly ok. But i also know that the 'devil is in the details'

(and btw, I also missed 'A.E.' )

Re: Source for Explorer

ericsnyder — Sat, 06 Apr 2013 14:57:36 GMT

Two things:

Bonita: The learning curve has been steep with poor community support on the forum. I had issues with users logging into the Bonita "Explorer" type app and having a connection issue with the database. It had to do with connection pools. It happens when you allow your session to expire. After you allow your session to expire then the inbox won't properly load the first few clicks. A number of other users had the issue as well. I tried to get it resolved but no luck and scant support. It seems to me to be a significant bug but it's not fixed yet. It has existed for some time now.

Also the Inbox has some issues like no ability to sort tasks and if there were more than one active item on a job then the inbox would just say "x tasks to be performed". When a user starts getting multiple "x tasks to perform" then it started getting confusing. They have to click on each one to determine what job it is for. The support for editing the Explorer app (User Experience) is just editing the css. Activiti with Vaadin seems a much better way. I am trying to use Explorer as a starting point for now.

I am becoming a passionate supporter of good open source projects where there is a strong and vibrant community of contributors. Apache, MySQL, JBoss, Java, there are lots of examples out there and more being added to the list every day. It just creates great software. Bonita just isn't quite there, I am hoping that Activiti is. Looks good so far.

Number two… I am still having noobie issues with my imported Explorer war. I have set up an eclipse project and have all the source code and can export a new war and can deploy that to the server. I am trying to add some new text fields and have followed these excellent instructions perfectly. When I add a new pachage to the src folder and deploy I get the exception:

Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.sharpline.fields.form.fields.TextAreaFormType] for bean with name 'com.sharpline.fields.form.fields.TextAreaFormType#53c37' defined in ServletContext resource [/WEB-INF/activiti-standalone-context.xml]; nested exception is java.lang.ClassNotFoundException: com.sharpline.fields.form.fields.TextAreaFormType

at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveInnerBean(BeanDefinitionValueResolver.java:270)
… 67 more

My new classes are not getting packaged in the war.

As a test I deleted the Explorer jar from the WEB-INF/lib folder and it did not get recreated either even though the source java files are in the src folder. The src folder is in the classpath. What could be wrong?

Your new classes (not .java but .class files) must be in the classpath. For instance, make a JAR using Eclipse and put that JAR file into /WEB-INF/lib directory of Activiti Explorer

ericsnyder — Tue, 09 Apr 2013 00:04:32 GMT

I am really sorry…
I deleted this project thinking it was something else.
Starting over… ops:

I set up a Git repository clone of Activiti on my local machine. (Master)
I imported a project from my local copy of Activiti
I converted the project to Maven sense.
I have performed a build and it was successful.

Now I have the entire Activiti project on my local machine. All I really want is to make modifications to Explorer. Is there an easy way to strip out all the other stuff that I am not interested in to convert this project into an Explorer only project? Explorer does not seem to be a project in it's own right.

i have created the A.E Project as follows:

1. Create the Dynamic Web Project (in Eclise EE Edition)
2. Unpack the "war. file of A.E located in Activiti Bundle distribution, that may be downloaded
3. Copy all needed libs from "WEB-INF/lib directory of unpacked war file
4. Navigate to <Activiti Bundle distribution>/libs and
5….copy the Activiti Explorer Sources JAR into /src directory of Eclipse Project
6. Unpack that JAR

Done;-)

P.S It may be better to use the maven magic–

Started over with your instructions. It took me all day to get the dependencies working with Maven. Still not right. I am now having issues with connecting to the H2 database server when I deploy the war:

My h2.jar file is in the WEB-INF/lib folder. I have both h2-1.3.170.jar and h2-1.3.171.jar in that folder. I also noticed that the files:
activiti-standalone-context.xml
activiti-ui-context.xml
applicationContext.xml

were not in the folder "WEB-INF/lib" I copied them there. It made no difference.
How do I get this project running? What else would I be missing?

You must to start the DBMS, that you use. Do you start the h2 DBMS? Do you install that DBMS?
If you use the Activiti 5.xx > 5.10 you must install it separatly. (Or you download the 5.10 and use only h2 from that bundle;- )

In WEB-INF/lib folder you need the h2 allways, because it an jdbc driver to connect with DBMS.
