Error using Java class in URL task Worlflow

Hi All,

I am using TeamSite 6.7.1. I created simple workflow.
start task -> URL Task -> end task
I created test.java file and put it in
/iw-home/local/config/lib/content_center/customer_src/src/p1
folder where p1 is package. and did a built from
/iw-home/local/config/lib/content_center/customer_src/
by command
/opt/teamsite/iw-home/iw-perl/bin/iwperl /opt/teamsite/iw-home/bin/make_toolkit.ipl
built is succesfull.

JAVA coad is

package p1;
public class test {

public static void main(String[] ss){
execute();
}
public static void execute(){

System.out.println("**** world");

}

}

in WF URL TAsk I did
Variable set to ClassName=p1.test
URI set to http://$IW_SERVER/iw-cc/urlexternaltask

But while running WF I am getting error in servletd_out.log as below

2010-06-30 05:15:33,964 [http-8080-Processor23] WARN com.interwoven.ui.datacapture.core.dcxp.DTDNodeOrderingStrategy (sumit.k.katre) - Error reading DTD http://localhost/iw-cc/datacapture6.0.dtd. Message: At line 2, column 3: Unexpected token: LT(null)

I gone through the devnet and find the same issue faced by one user but did get exact sotion.

    }
}

You do not have the correct signature for the execute method - there are parameters that you need to accept and main() will only be called if you are manually running the code - not by the workflow engine. You need to spend more time with the product documentation and javadocs, and probably use an IDE that helps you create the code correctly.

This is a completely separate issue - It's now identified by IWOV as "TS-11724" - it requires editing

IWHOME/local/config/datacapture6.0.dtd

to be syntactically correct and copying the [fixed]

datacapture6.0.dtd

into

IWHOME/httpd/webapps/content_center/

Thanks Ghoti,

As I am new to JAVA as well as Workflows so I did not find proper document (PDF) related to JAVA development specific to WorkFlows(TeamSite). I went through "wfm_1001_user_v01_en.pdf" and doc available at "/iw-home/httpd/webapps/content_center/WEB-INF/lib/datasourcedoc.jar" in server.

It would be great if someone suggest me that which document (specific to development of teamsite workflow JAVA class) will be good to start with and where it will be in Autonomy support site? If you already have please share with me on devnet Smiley Happy

Ghoti: I searched for article "TS-11724" in Autonomy support site and Devnet but did not get any result. Can you Please share URL Smiley Happy

And as far as this below error is concern it is coming in "servletd_out.log" only when I am instantiating Workflow.

Hi Sumit-

Follow the same workflow document and go through "Datasource Example" section. This will give you basic understanding of how to push your java class and call this into your workflow.

Also try to learn J2EE framework (servlet) to understand how request and response works.

Thanks Faizi,

Can you plaese also help me in this error msg. which I am getting in "servletd_out.log" file.

There is NO article - this is something that I logged with support several weeks ago, was able to get them to reproduce the issue in-house, and had them register it as a bug to be fixed in a future release.

You can pretty much ignore the error - it's annoying, but generally harmless, or you can fix the DTD file and copy it into place to get rid of the message.

Your code is wrong. It is not necessary to put in a main method. Your execute method needs parameters. You'll also need the task object and use a chooseTransition method in order for the workflow to go to the next task.

Thanks Mart,

Now I have modified my java coad but still My workflow not moving to next task(dummy task). Can you please help me where I am missing.

package p1;

import java.util.Hashtable;
import com.interwoven.cssdk.common.*;
import com.interwoven.cssdk.workflow.*;

public class test implements CSURLExternalTask {
public void execute(CSClient client, CSExternalTask task, Hashtable params) throws CSException {
System.out.println("Running gc.dfait.iwov.workflow.favorites.RestoreFavorites");
task.chooseTransition("FlowToDummy", "Comment to Link");
}
}

Even in my workflow next task after URL task is dummy task. As this code I have taken from DevNet I don't know actual structure of "CSURLExternalTask" interface. and "chooseTransition" I do not know where is document regarding this. So can you please help me to make this workflow work as well as tell me where I can get document regarding this interface "CSURLExternalTask". I have documents "modelerworkflowapidoc" but did not find any thing regarding "CSURLExternalTask" interface.

Thanks & Regards

In your workflow - does your External Task actually have a transition link named "FlowToDummy" - exactly as shown (no spaces, camel-cased) - coming out of it?

sumitkatre

Yes Ghoti, link is having exactly same name. I gave this name to that link which is connecting URL task and Dummy task

URLTask-----FlowToDummy------>dummy task

Are you seeing your print statement show up in IWHOME/local/logs/iwui/servletd_out.log?

For CSSDK docs - you should look at the CSSDK doc jar file - I'm not looking at a server right now, but I believe it can be found in IWHOME/cssdk/docs/ or something like that.

HI Ghoti,

No, print statment not showing any thing on log file. I think my java class not at all getting called, is there any other way to check or do i need to configure my java class some where?

Testing I did : Once I tried deleting java file from respective pacakage and did built, means there was no java class where workflow was expecting even though workflow was not writting any error message in servelet_out.log file. It means Workflow was not at all trying to search JAVA file which is mentioned in className variable of URL task. Am I missing some thing please suggest.

Yes I got the cssdk document at location where you(ghoti) have mentioned

"/iw-home/cssdk/docs"

Thansk & Regards

If you're not seeing the print statement in the servletd_out.log then it's a pretty good chance you're not actually calling your Java class (which looks like it is coded correctly for the simple test).

The ExternalTask ClassName property needs to be set to the proper dot-path of your class.

sumitkatre

Thanks Ghoti, here are my configuration

* What is the full path to your class within the IWHOME/local/config/lib/content_center/customer_src tree?

/iw-home/local/config/lib/content_center/customer_src/src/p1/test.java

* What is the complete value you provided for the ClassName property of the ExternalTask?

Ghoti I am using URLexternal task

ClassName
p1.test

* Is it safe to assume that you ran make_toolkit.ipl from the correct directory and that it completed successfully?

Ran "make_toolkit.ipl" from below folder

/iw-home/local/config/lib/content_center/customer_src/

Please let me know if I am missing something
here I am attaching ipm as well as java file
