CSSDK - "Creating a Client Object" sample code

Adam Stoller

Environment[indent]TS 671 SP1 P2
Solaris 10
CSSDK 3.1.0[/indent]Issue[indent]I'm looking at page 29 of the "Interwoven®
ContentServices™ for TeamSite - Cookbook - Release 2.5" (is there a 3.1.0 version of this document?) and there's some sample code that looks [somewhat] like this:

import com.interwoven.cssdk.common.*; 
import com.interwoven.cssdk.factory.*;
import java.util.*; 
import java.io.*; 
public class foo { 
    public static void main(String[] args) { 
        // ... variable declarations ...
        Properties props = new Properties(); 
        try { 
            props.load(new FileInputStream("path-to-properties-file")); 
        } catch ( FileNotFoundException fnf ) { 
            System.out.println( "The properties file was not found" ); 
        } catch ( IOException io ) { 
            System.out.println( "Some type of I/O exception has occurred" ); 
        }
System.out.println("props: " + props); // debugging 
        // get the factory 
        factory = CSFactory.getFactory(props); 
        name = factory.getClass().getName();
        // ... more code ... 
    } 
}

My CLASSPATH looks essentially like this:

IWHOME/cssdk/cssdkjni.jar:IWHOME/cssdk/cssdkiface.jar:.

I made sure that

IWHOME/tools/java/bin

is at the front of my PATH and I run:

javac foo

No errors - good, then I run:

> java foo
props: {com.interwoven.cssdk.factory.CSFactory=com.interwoven.cssdk.factory.CSLocalFactory , cssdk.cfg.path=/opt/appbin/TShome/cssdk/cssdk.cfg}
Exception in thread "main" com.interwoven.cssdk.factory.CSFactoryInitializationException: (Factory initialization failed)
        at com.interwoven.cssdk.factory.CSFactory.getFactory(CSFactory.java:132)
        at foo.main(foo.java:23)
Root cause:

        at com.interwoven.cssdk.factory.CSFactory.getFactory(CSFactory.java:127)
        at foo.main(foo.java:23)

Hmm, I know I included cssdkjni.jar on my CLASSPATH - and:

> unzip -l IWHOME/cssdk/cssdkjni.jar | grep LocalFactory
   8498  08-28-07  15:22   com/interwoven/cssdk/factory/CSLocalFactory.class

The jar file certainly seems to include the desired class information.

I've tried explicitly adding -cp $CLASSPATH on the command line when running the program - no help. I've swapped the first two elements in the CLASSPATH - no help. I've swaped the first two 'import' statements in the source file - no help.[/indent]

So - what am I missing? / what am I doing wrong?

Goti,

1 : make sure you have CSSDK installed and licensed in your TS ENV. (you are TS expert and that should be an easy task for you, you mentioned in your post that is done anyway )

2: I would suggest that you use an IDE to develop your code in ( even if that code your are using was given by Interwoven, you still need to ensure that your lib are included and no syntax errors etc. The IDE shall help you out in that. I would suggest that you use eclipse IDE as it is the IDE that Interwoven are using i think to develop there code.

3: i would suggest that you use this servlet instead of the java class provide d in the cook book

content_center\customer_samples_src\src\com\corp\custom\CustomServlet1.java

4 : make sure you compile everything successfully. take the jar that was created and then put it the correct location , run tk.

5 : you really dont need to have the Factory object , you just need to get the CSClient object from the request object and you should be good to go.

I'm kind of looking to create what is essentially a CLT so that I can easily test things without having to go through the TS GUI (and make_toolkits.ipl, etc.) - so I don't think that a servlet helps me in that case (am I right?)

I don't currently use an IDE - I suppose I could try downloading one - but I hate having to re-train my fingers for different editing applications - I'll think about it.

I assume '5' is on the assumption that I'm doing this as a servlet - which, as I have indicated, is not what I want to do. I want the ability to easily do:

and do my development as rapidly as possible that way. Maybe it's just being an "old dog" - but that's the way I like to do my initial coding (unless I'm trying to develop a GUI).

Let me start out with saying that I'm trying to create a stand-alone program to be able to do rapid test-development of code using CSSDK without disrupting other developers and/or users of the TS server (which would be the case if I have to put this into IWHOME/local/config/lib/content_center/customer_src and run make_toolkit.ipl every time I make a change - right?) So perhaps the first question is:

".So - am I just banging my head against a wall that won't fall down - or am I missing some piece of elfin-magic that will make this work?

Take a look at the Ant's build script: iwhome/local/config/lib/content_center/reference/build.xml.
That's the one IWOV uses in the make_toolkit, it just *may* help

I was kind of hoping to put off learning ant until I had made a reasonable headway into learning how to create java code to replace my built-up library of perl code... why is it that things that are supposed to be "better" seem to be so much "harder" ? ;-)

Migrateduser

Are you running this on the TS server itself? Are you using SOAP to connect or JNI? If you are using JNI, you will need to be on the TS Server itself. If you are using SOAP, you can connect through a client. Also, try to add your current path to your classpath. Have you tried to download the cssdk samples, and try running the CSHelloWorld class file?

I did not mean that you have to really use Ant to build your code (you may of course). Look at this File regardless, see what IWOV does
with JARs, etc... It just *may* help to build CLASSPATH, LIBRARY_PATH and the llike.

Btw, apologise if I state the obvious, but - have you checked that you have a reading access to the LD_LIBRARY_PATH entries?

I'll try to remember to take another look when I get a chance (right now I'm off-site at a hotel and don't have remote access to the customer server)

Sorry to re-raise this old thread but was there any conclusion?

I've seen a number of threads on the CSHelloWorld CSSDK which have issues similar to the above and I've pretty well followed the above process with the same results on both my client and TeamSite server. What little hair I had left has now been pulled out.

Exception in thread "main" com.interwoven.cssdk.factory.CSFactoryInitializationException: (Factory initialization failed)
at com.interwoven.cssdk.factory.CSFactory.getFactory(CSFactory.java:133)
at Foo.main(Foo.java:22)
Root cause:
java.lang.ClassNotFoundException: com.interwoven.cssdk.factory.
...

Other than keep adding jars until hopefully CSHelloWorld works has anyone got this working. If so what is in their classpath ?

thx

It's possible here's how I did it:

export LD_LIBRARY_PATH=/opt/iw-home/cssdk:/opt/iw-home/lib:/opt/iw-home/iw-webd/lib:/usr/local/ssl/lib:/usr/local/lib

java -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y -cp .:../lib/dom4j-1.6.1.jar:../lib/cssdkiface.jar:../lib/jaxen-1.1.jar:../lib/sharedutils100.jar:../lib/cssdkjni.jar UpdateModifiedByjava

This will start the program with a debug port of 8787 so you can do remote debugging if necessary.

Good luck.

These are the jar files you'll need in your classpath:

Many thanks guys I'll give it a try first thing tomorrow !

For completeness...

Linux TS 672 + cssdk3.1.0 + WFM 1.0.1.0
Working from my client machine (in eclipse)
I was unable to get working with the jars from IW CSSDK3.1 support download

I'd recommend
* downloading the Workflow Modeller (you'll need this for the cssdksoap.jar that does not come with TeamSite)
* ensure all WFM jars are in your project classpath
* CSHelloWorld should then be good to go

other possible gotchas:-
there are a couple of jar file discrepancies between WFM jars and the cssdk3.1.0 pack from IW e.g. saaj.jar and xercesImpl.jar and probably further discrepancies with the TS server itself

Did anyone get a clean way of working this from Eclipse. I am trying it hard and still it is throwing me error.

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
CSFactory cannot be resolved to a type
CSVersion cannot be resolved to a type
CSFactory cannot be resolved
CSException cannot be resolved to a type
e cannot be resolved

I am on TS 6.7.1 on Windows. With CSSDK 3.1.

Thank You

Sorry if you posted this somewhere, but this thread is a mess. But if you're working in Eclipse in a standard "Java Project", please list the referenced JARs for the project or look at the build path for the project and list the Libraries. Then we can find out why the compiler can't find them.
