URL Task Doesn't Transition

I am on TS7.2.1 on Linux. I took a basic Author Submit With Deploy. I tweaked it a little by introduction couple of tasks, both URL tasks, one for email and one for just generating a file-list. I incorporated this URL task between Review and Submit tasks.

I have defined following attributes, for URL task

ClassName - com.interwoven.datasource.examples.FileListGenerate
TaskBeanId - workflow.task.FileListGeneration
ImmediateTransition - true

My Datasource setting is a given below.

[html]

Filelist Datasources
com.interwoven.datasource.examples.LogWriter
TSDEV
http://TSDEV
com.interwoven.cssdk.factory.CSSOAPFactory

[/html]

And LogWriter.jave is a class which basically writes a text file out. This calls doesn't have a return value and ofcourse doesn't have a main.

I see that the file is not even getting created. and my Workflow is stuck at FileGenerate task. Can anyone point me if i am missing anything?

Also can anyone RTFM me as what are mandatory attributes for a URL task, I think only class and the Command URI are necessary which in my case is set to "http://$IW_SERVER:$IW_PORT/iw-cc/urlexternaltask"
Thank You

Oh boy, you're way out in left field with this..

The ClassName on the task should point to a class that implements the URLExternalTask interface. The fact that yours is placed in a "datasource" package implies that you probably didn't get that right.

The TaskBeanId parameter won't get used unless your ClassName is DelegatingUrlExternalTaskProxy. This is for when you want your task to be Spring-aware and is mutually exclusive from having a custom ClassName.

Immediate=true on a URL task doesn't make any sense whatsoever, unless you're actually talking about a CGI task, in which case you're in a different left field entirely with the rest of this.

Your LogWriter datasource will never print anything to the logs unless you have something that actually requests data from it. My guess is you don't.

When you post any follow-up questions, post your java code along with it to help drive the discussion.

Thank you for the response. I am new to calling Java class in the WFM. There is no clear cut definition anywhere in the documentation which identifies which one to use and when. For example i will leave CGI task out for now. I am into URL task or external task where I can just mention class and it should run that class and produce results. Atleast i know that my class doesn't have a return type and ofcourse do not have a main function in it.

I want to get a simple class to be executed in the WFM using either an External or URL task. For now I am not returning anything. Here is the Java class file as needed.

################LogWriter.java#############

package com.interwoven.datasource.examples;

import java.io.*;

public class LogWriter {
String[] anArray = {"/images/abc.jpg", "/images/xyz.jpg"};
String jid = "23452";
public void writing(String[] anArray, String jid){
String reqJobID = jid;
try{
File startLog = new File("/logs/Interwoven/TeamSite/logs/logs/OD_"+reqJobID+"_FileList.log");
FileOutputStream is = new FileOutputStream(startLog);
OutputStreamWriter osw = new OutputStreamWriter(is);
Writer w = new BufferedWriter(osw);
for (int m=0; m {
w.write(anArray.toString());
w.write("\n");
}
w.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

}
}

Can anyone point me to a good example.

From the looks of it, I think you need basic Java training before even attempting teamsite development. I mean, from your latest post it's somewhat evident that you're not familiar even with object-oriented programming.

Thank you for your opinion, clearly undermines my purpose of even looking for any pointers here to get a basic task going (which has nothing to do with OOPS concepts of Java). Stupid documentation has no clarity or well defined examples at all except emails task using URL and bunch of CGI tasks. I guess who compiled it has not clue about it either.

Anyways thank you for your time. I will figure it out and post a solution here.

I disagree. If you have no previous experience working with this platform, then knowing the very basics of the language in which it's written is the key to putting the pieces together and understanding how it works. Sure, you could probably figure out how to mash together an external task, but how are you going to know if there's a better way to do it without the overall picture? I've seen too many broken TS implementations to know that fudging your way through it is a train wreck waiting to happen, and it's a very expensive train at that. Shelling out $2-3k on training is a small price to pay in comparison. Getting spoon-fed boilerplate code on forums doesn't count.
