DeclarativeWebScript not working

kasperba — Thu, 21 Jun 2007 09:39:30 GMT

I have written a REST-signin call based on the Alfresco 2.1dev REST-login but when I call it from a browser then I get an exception which says the following:freemarker.core.InvalidReferenceException: Expression ticket is undefined on line 2, column 11 in com/wannakey/user_signin.get.xml.ftl.After so

I suspect your Spring bean has not been hooked into your Web Script.

If you switch on:

log4j.logger.org.alfresco.web.scripts=debug‍

log4j.properties‍

and re-start the server (or 'refresh web scripts' from /alfresco/service/), all registered web scripts are logged including their Spring bean

e.g.

Found Web Script org/alfresco/repository/loginticket.delete (desc: org/alfresco/repository/loginticket.delete.desc.xml, impl: webscript.org.alfresco.repository.loginticket.delete, auth: user, trx: required, format style: any, default format: xml)

If you have:

impl: webscript_default

then your bean is not hooked up. You need to adjust the id of the Spring bean.

Re: DeclarativeWebScript not working

kasperba — Thu, 21 Jun 2007 10:14:49 GMT

You are right about IMPL = webscript_default.

12:09:52,875 DEBUG [org.alfresco.web.scripts.DeclarativeWebScriptRegistry] Found Web Script com/wannakey/user/signin.get (desc: com/wannakey/user/signin.get.desc.xml, impl: webscript_default, auth: none, trx: required, format style: any, default format: html)

"adjust the id of the Spring bean"? you just lost me there ops:

If you could describe what I should do because I can't remember that I have given this spring bean an id and I wouldn't know how.

Re: DeclarativeWebScript not working

davidc — Thu, 21 Jun 2007 10:26:35 GMT

Ok.

<bean id="webscript.com.wannakey.signin.get"
class="com.wannakey.user.SignIn" parent="webscript"
abstract="false" singleton="true" lazy-init="default"
autowire="default" dependency-check="default">
<property name="authenticationService" ref="authenticationService" />
</bean>

The id of a Web Script bean must comply with the following naming convention:

webscript.<packageId>.<serviceId>.<httpMethod>‍

So, I know your serviceId (signin) and httpMethod (get) are correct, so it must be the packageId that's wrong.

Where have you placed your script (in which folder)? The folder is your package. Replace / with .

e.g. Alfresco's login script is in the folder

org/alfresco/repository‍

therefore its packageId is

org.alfresco.repository‍

and its web script bean id is

webscript.org.alfresco.repository.login.get‍

Yes, that was the problem.

Thanks for you help.

where did you put your context.xml?

I placed mine in Alfresco\tomcat\shared\classes\alfresco\extension,

but returns an error:

Im pretty sure the bean ID naming convention is correct, maybe its the class??

Having trouble gettin my bean to bind with my web script…

If anyone can help

I put my custom context.xml in C:\Alfresco\tomcat\shared\classes\alfresco\extension.

I put my desc.xml and ftl file in
C:\Alfresco\tomcat\shared\classes
then, create a directory within \templates\webscripts\<namespace>\desc.xml, etc.

Then I put my compiled JAR file of my .java file in
C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib

I know the naming convention in my context.xml is correct. Are these the steps I need to create a java-backed webscript, and bind the bean into the webscript???? Because, I still keep getting class not found error.

Thanks

Is

com.tsgrp.alfresco.webscript.SignInWebScript

in your classpath?

This is in my context.xml

Re: DeclarativeWebScript not working

davidc — Mon, 07 Jan 2008 17:37:07 GMT

Is your SignInWebScript.class file in your classpath?

Re: DeclarativeWebScript not working

tsgpartner_mui — Mon, 07 Jan 2008 17:43:16 GMT

i dont quite understand what you mean.

so instead of a jar file from my .class file, I need to put that somewhere or have that stated in my context.xml file??

Re: DeclarativeWebScript not working

davidc — Mon, 07 Jan 2008 18:06:30 GMT

Is your class in the java classpath? - either explicitly or implicitly via a .jar.

Nothing to do with the context.xml.

Re: DeclarativeWebScript not working

tsgpartner_mui — Mon, 07 Jan 2008 18:16:58 GMT

As I stated above, after I compiled my java file. I took the .class file and converted it to a .jar file. then moved that file into the WEB-INF folder.

Thats all I did. So, I believe the class is in the java classpath, if thats what you are lookin for.

I'm just learning how java works currently.

Re: DeclarativeWebScript not working

davidc — Mon, 07 Jan 2008 20:29:51 GMT

Well, I suggest you grasp the basics first - it's essential to understand the classpath.

Assuming you're using Tomcat, you have two choices:

a) create the folder /com/tsgrp/alfresco/webscript in <tomcat_home>/webapps/alfresco/WEB-INF/classes and place your class in it

or

b) create the folder /com/tsgrp/alfresco/webscript in your .jar file and place the .jar in <tomcat_home>/webapps/alfresco/WEB-INF/lib

Re: DeclarativeWebScript not working

tsgpartner_mui — Mon, 07 Jan 2008 23:22:24 GMT

I understand. Thanks for the help.

I was able to get rid of the 'class cannot be found' error, but unfortunately I have another one. Right now, I'm just trying to test how java-backed scripts work, so in the error below I have a hello world java script I created. Basically I want to call the script from the url and then, use java to return a message "hello world' and would be displayed by the response template.

Also, as an additional question, when creating java-backed webscripts, is the response template optional?
(From the wiki, it states that theres one or more response templates when creating a webscript at least for javascript. )

Going back to java scripts, java code can build a data model that's available to "Response" templates. The Java to be executed is placed into the executeImpl method. Are there any examples of that in documentation?

Thanks once again

Re: DeclarativeWebScript not working

tsgpartner_mui — Tue, 08 Jan 2008 17:16:39 GMT

I was able to build a data model to my template in java code.

by running the code in eclipse, it outputs what i want to see and theres no indication of errors at all.

but then I try to start alfresco with tomcat, I still receive that invalid property error.

SO
i tried moving the context.xml file to C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco, and

moving my desc.xml and ftl file to
C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\extension\<namespace>\files…

and then I was able to successfully start Alfresco without errors n such.

but it still says impl:webscript_default for my helloworld script
therefore, its still has not correctly bind to the script.
I tried hitting script via url, returns 500 error.

Re: DeclarativeWebScript not working

tsgpartner_mui — Tue, 08 Jan 2008 18:13:41 GMT

Any thoughts to why I cannot get this spring bean to bind correctly

Re: DeclarativeWebScript not working

davidc — Tue, 08 Jan 2008 21:41:16 GMT

You need to give your web script bean an appropriate id. The convention for the id is described at

http://wiki.alfresco.com/wiki/Web_Scripts#Java-backed_Web_Scripts

If you still have trouble dump your bean xml definition and web scripts files here at the forum.

Re: DeclarativeWebScript not working

tsgpartner_mui — Wed, 09 Jan 2008 16:30:30 GMT

I actually got it to work now.

Was able to fix my errors and start tomcat.

The funny thing was that it didnt recognize my script. I went to web scripts home, refresh and still didnt show my script, signin.

So then I just upload the desc.xml and ftl files in the repository, then It was able to recognize the script. And now it works.

Thanks for all the help david.

But one question, how come it worked but I had to upload the files in the repository??

Re: DeclarativeWebScript not working

robertito — Tue, 12 Feb 2008 16:03:24 GMT

Good Afternoon,

In your post you mentioned that you built an AMP for that Web Script. Where did you place the web script descriptor? I could only add it to Alfresco by doing it explicitly in folder [Company Home > Data Dictionary > Web Scripts].
Is there a way to deploy them automatically by including them in the AMP?

Thank you in advance.
Kind Regards,
robert
