Test new model definition : where is the 'TestModel&quo

[anweber]

Hello,

     I have written a model definition and I should like to test if it is valid.  The "Data Dictionary Guide" tells me "execute the org.alfresco.repo.dictionary.TestModel".  My problem is that I do not know where this class is.  I loaded the executable version 1.2.0 bundled with Tomcat (I have not the source code).

   Thanks for your help,

The TestModel class is available in the source bundle.  You'll also find it in the repository.jar inside of the .war file of the Tomcat bundle.

OK.  Thank you.  I found this class.  To execute the "TestModel" command, I had to add some paths in the CLASSPATH.  The resulting command to test "customModel.xml" is (if executed from the c:\Alfresco\tomcat\shared\classes directory) :


java -cp ".;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\commons-logging.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\core.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\repository.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\jibx-bind.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\jibx-run.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes" org.alfresco.repo.dictionary.TestModel alfresco/extension/customModel.xml

I am trying to add a custom model to my repository conform the Data_dictionary_guide (WiKi pages):

From the folder

C:\Alfresco\tomcat\shared\classes

I run the following TestModel check:

C:\Alfresco\tomcat\shared\classes>java -cp ".;C:\Alfresco\tomcat\webapps\alfresc
o\WEB-INF\lib\commons-logging.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\li
b\core.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib\repository.jar;C:\Alf
resco\tomcat\webapps\alfresco\WEB-INF\lib\jibx-bind.jar;C:\Alfresco\tomcat\webap
ps\alfresco\WEB-INF\lib\jibx-run.jar;C:\Alfresco\tomcat\webapps\alfresco\WEB-INF
\classes" org.alfresco.repo.dictionary.TestModel alfresco/extension/blablaModel
.xml

And get this exception:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/alfresco/
repo/dictionary/TestModel (Unsupported major.minor version 49.0)

I am using the Alfresco 1.4 Community Preview edition based on tomcat and installed on Windows XP.


Two documents where prepared conform the developers guide (wiki pages):

blablaModel.xml and related example-model-context.xml

example-model-context.xml contains the following addition inside the Bootstrap bean:

            <list>
                <value>alfresco/extension/exampleModel.xml</value>
                <value>alfresco/extension/blablaModel.xml</value>
            </list>


are placed in the following folderpath:

C:\Alfresco\tomcat\shared\classes\alfresco\extension

The exception "Unsupported major.minor version 49.0 leads me to believe that there is some
configuration problem.

I setup Alfresco in C:\Alfresco with the install wizard.

=> Do I need to install the SDK as well in order to be able to run the TestModel class or in fact do any configuration/development?


Please help


Kind regards,

Alex :wink:

Are you possibly using jdk 1.4 to execute the test?

This is a typical error that occurs when a class has been compiled with a more recent version of the JDK (in this case 1.5) and ones tries to execute it with a former version.

Check the output of

java -version‍

If you're using JDK 1.4, install the latest Sun JDK and configure your path to point to the right java binary.

Hi David,

Thanks I checked the java -version,

java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)

java_home is pointing to the jre within the alfresco installation (c:\alfresco\java\bin), which is the above jre (for alfresco 1.4 community preview edition that is). Same entry in the classpath.

Still getting:

:cry:

No other JRE or JDK is installed on my test server.

This is another error this time. It seems you're missing a few classes in your classpath. From the above error you're at least missing a jar containing the XML pull parser that reads XML files. The jar is named 'xpp3-1.1.3_8.jar'. Try to add it and see if it fixes your issues. Frankly speaking, if your model is not too complex, I would only check its well-formedness with a standard viewer (Firefox ?) and the try to start Alfresco. You might save some time
