Import Jar in Component

Anonymous — Wed, 27 Sep 2017 14:55:53 GMT

Hello,

I am writing a component for TOS 6.4.1 in which I want to use ARX Anonymasiation (http://arx.deidentifier.org/). I downloaded the jar from the homepage and importet it to my component (see the XML) and added it to the Java Build Path in TOS.

 <IMPORTS> 
      <IMPORT MODULE="libarx-3.6.0.jar" NAME="libarx" REQUIRED="true"/> 
    </IMPORTS>

Now I want to use one of the classes.

In the _begin.javajet file I write

imports="
		org.talend.core.model.process.INode 
		org.talend.core.model.process.ElementParameterParser 
		org.talend.core.model.metadata.IMetadataTable 
		org.talend.core.model.metadata.IMetadataColumn 
		org.talend.core.model.process.IConnection
		org.talend.core.model.process.IConnectionCategory
		org.talend.designer.codegen.config.CodeGeneratorArgument
		org.talend.core.model.metadata.types.JavaTypesManager
		org.talend.core.model.metadata.types.JavaType
		java.util.List 
		java.util.Map
		org.deidentifier.arx.ARXAnonymizer
	" 
%>
<% 
CodeGeneratorArgument codeGenArgument = (CodeGeneratorArgument) argument;
INode node = (INode)codeGenArgument.getArgument();
String cid = node.getUniqueName();

 	
org.deidentifier.arx.ARXAnonymizer anonymizer = new org.deidentifier.arx.ARXAnonymizer.ARXAnonymizer();
%>

but I keep getting an error message "The import org.deidentifier cannot be resolved".

Thanks for your help.

Hello,

Have you put your jar file in your custom component folder? Can you see it from modules view?

Best regards

Hallo,

Yes the Jar is in the component folder. When I open the component Designer I can see it.

When I loaded the component for the first time it told me I need to install a required jar and I installed it with the component view of my Job.

Thank you for your reply.

You are still getting an error message "The import org.deidentifier cannot be resolved"?

Do you have any idea why I get this error message?

Thanks,

Hello,

in the meantime I added the URLPath to the XML.:

 <IMPORTS> 
      <IMPORT MODULE="libarx-3.6.0.jar" NAME="libarx" REQUIRED="true" UrlPath="D:\Program Files\TOS_DI-20170623_1246-V6.4.1\plugins\org.talend.libraries.custom_6.4.1.20170623_1246\lib\libarx-3.6.0.jar"/> 
    </IMPORTS>

But that does not help, either

Greetings,

Miri

@ miriull referring to your _begin.javajet file, Shouldnt the line of code be
org.deidentifier.arx.ARXAnonymizer anonymizer = new org.deidentifier.arx.ARXAnonymizer();

Instead of

org.deidentifier.arx.ARXAnonymizer anonymizer = new org.deidentifier.arx.ARXAnonymizer.ARXAnonymizer();
??

Hey,

You are rigth, there is a mistake. Anyway it doesn't even find org.deidentifier so that doesn't seem to be the problem.

Can you upload your component XML file please?

You can try changing custom component location.
Alternatively, you can use tLibraryLoad component to load libarx jar explictly in your talend job.

I already tried more than one location for the as as well as the whole component.

The import with the tLibraryLoad only works if I write my code in tJavaFlex. But the import of the jar for the component doesn't seem to work. Furthermore I cannot connect tLibraryLoad with my component.

I also think that this is not the best solution: I want to offer the functionality of arx within this component. When the user has to load the Jar in an external component he doesn't need the extra component any more..

I agree, this is not the solution.
What i meant is,you can test the new component using tLibraryLoad. (I am sure jar would be available to new component).

The probable reason for your error is , not the latest XML for your component is being compiled by studio. In which case , you should try by changing your custom component location and workspace.

Even when I use tLibraryLoad I get the error message. My Job looks like that

(File Input is a simple example csv for the analysis)

I copied the component to a different direction and changed the component path of TOS to this folder but that doesn't help either.

Could there be a mistake in the import in the javajet?

Remove org.deidentifier.arx from import section in javajet.
I guess import section is for library already packaged with jet engine.

Hope that helps !

It doesn't help.

The line

org.deidentifier.arx.ARXAnonymizer anonymizer = new org.deidentifier.arx.ARXAnonymizer();

gives 2 errors: 2 times "org.deidentifier cannot be resolved to a type"

Did you use tLibraryLoad this time?

It is the same job as the Screenshot you can see, so yes
