How to retrieve files attached to a task ?

nirali

TS721, WS8
-------------
I am attaching an externaltask to default workflow. I want to retrieve files submitted to staging and check all extensions before it is actually submitted to staging.

How can I retrieve files submitted to staging in an externaltask ? I am using java program to check files for extensions. Call an ipl file in externaltask, which in turn invokes java code.

Thanks

uh........wtf?

Why not use a URLExternalTask and skip the overhead of two unnecessary forks?

I want to do that using java.

I am caling jar file from Perl script as follows
[html]
__INSERT__("");

__INSERT__("");
[/html]

Where $java_call runs an ipl script, which in turn invokes scan_files.jar

$java_call = "d:\iw-home\TeamSite\iw-perl\bin\iwperl.exe
d:\iw-home\TeamSite\local\config\wft\ecm\runJava.ipl"

.....
my @args = ("java", "-jar", "C:/projects/Deploy/scan_files.jar");
   system(@args);.....

scan_files.jar invokes a java class, where files will be checked for extensions.

Now my confusion is how to pass files to this java class, which is invoked perl script ?
Instead of running a Perl script, can I run a java class as
$java_call = "d:\Program Files\jdk1.6.0\jre\bin\java
C:/projects/Deploy/scan_files.jar"

Again, how do I pass files to the class invoked ?

In cssdk manual, I read CSClient is the one which can be used for this. I am not sure how to use CSClient. This is how it is in PDF, but thats for HTTPServlet. Can I use it this way in a class, which is invoked from outside and not from TeamSite ?

Again question comes down to use of CSTask to get files

CSClient client = (CSClient) request.getAttribute("iw.csclient");

CSFile getFiles() - Gets files attached to the task, but how to provide taskid to getFiles() OR how to instantiate CSTask for this externaltask ?

Please explain with some sample code. This is first time I am using this and I am literally confused.

I am using wft. Can we use URLExternalTask in wft ?

Thanks

You're kinda off in left field with a lot of this, so er.. hire someone that knows how to do this stuff already?

No, you cannot use URLExternalTask in wft but you'd save yourself this entire giant headache if you just switch to wfm, especially if you're already going with a java-centric implementation.

Quick answers to the rest of your post:

Now my confusion is how to pass files to this java class, which is invoked perl script ?
Command line arguments. This will break when the number of attached files is large enough, as an operating system limitation. Or, you can pass just the task ID and retrieve the task via the CSSDK.

Instead of running a Perl script, can I run a java class as ...
Yes you could, but you still need to callback the workflow when you're done so don't forget about that.

In cssdk manual, I read CSClient is the one which can be used for this.
Instead of "can be used" you should interpret this as "must be used". Forking to Java and then forking a bunch of CLTs is just an insane perversion of the architecture.

I am not sure how to use CSClient. This is how it is in PDF, but thats for HTTPServlet. Can I use it this way in a class, which is invoked from outside and not from TeamSite ?
The examples for obtaining a CSClient do not apply to you, because you're building a standalone client rather than a Servlet or a URLExternalTask. That said, there's quite a few posts on these forums about instantiating a CSClient manually from a CSFactory. This is not trivial or obvious, so I'd again strongly suggest you switch to wfm and avoid all this.

I have found following info from a thread

Properties properties = new Properties();

properties.setProperty("com.interwoven.cssdk.factory.CSFactory",
"com.interwoven.cssdk.factory.CSSOAPFactory");

properties.setProperty("serviceBaseURL","url");

String username = "";
String password = "";

CSFactory factory = CSFactory.getFactory( properties );

CSClient client = factory.getClient
( UserName,Roles, Password,Locale ,Application Context,host);

Wheer does Properties class come from ? I checked another post in same thread, it imports everything except Properties.
Do I have to create properties file, like the one I am creating for logging in java ? If yes, what are the properties must be set in this file ?
In which path do I keep properties file ? Do I just keep it in classpath ? OR Does a propertirs file exist by default in TeamSite ?

FOUND IT. ITS IN java.util.*. Sorry did not look at this import.

Rick Poulin

java.util.Properties. Get yourself a Java IDE like Eclipse or IntelliJ, it'll make your life that much easier.

The properties object you're creating here is an in-memory object and, in this particular case, has no association with a properties file.

From the posts above, it appears that I have to use CSFactory to get CSClient object. In the code below, CSCLient object is obtained without using CSFactory. How does that work ?

package com.rbc.teamsite.finance;

import java.io.FileReader;
import java.io.PrintWriter;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import com.interwoven.cssdk.common.CSClient;

public class ReportDriver {

 private static String userid;
 private static String password;
 private static String teamsiteHost;
 private static String filePath;
 private static String cssdkconfigfile;
 private String applicationName;
 public static String getCssdkconfigfile() {
  return cssdkconfigfile;
 }

 public static void setCssdkconfigfile(String cssdkconfigfile) {
  ReportDriver.cssdkconfigfile = cssdkconfigfile;
 }
 private String applicationEditionPath;
 private static String reportLocationPath;
 private static String mgmtReportLocationPath;
 private static String baselineDate;
 public static String getBaselineDate() {
  return baselineDate;
 }

 public static void setBaselineDate(String baselineDate) {
  ReportDriver.baselineDate = baselineDate;
 }
 private static CSClient csClient;

 private static CSClient getCsClient() {
  return csClient;
 }

 private static void setCsClient(CSClient csClient) {
  ReportDriver.csClient = csClient;
 }..........

I am passing taskid to the java class as follows. Now how can I use this taskid ? Which object do I associate this taskid to ?
my @args = ("java", "-jar", "C:/projects/Deploy/scan_files.jar", "$taskid");
system(@args);.....

public class ScanFiles{
      .........
public static void main(String [] args){

  ScanFiles ssf = new ScanFiles();
  int taskid = Integer.parseInt(args[0]);
  try{
  ssf.csTask = ssf.getCsClient().getTask(taskid);
  ssf.csFiles = csTask.getFiles(query);
  }
  catch(Exception e){

  }
 }
}.....

What do I provide as query ? I want all files attached to task.

I checked other method CSAreaRelativePath[] getFiles() , but it returns CSAreaRelativePath, while I need all files attached to task

Thanks

Hard to say for sure without knowing the execution context, but it looks like the CSClient here would be provided by the caller (or by Spring injection, but that wouldn't work properly in this case, so let's hope not).

I am passing taskid to the java class as follows. Now how can I use this taskid ? Which object do I associate this taskid to ?
The posted code snippet looks like it's using it just fine....

Don't provide one, use this instead:
CSFile[] files = cstask.getArea().getFiles(cstask.getFiles());
