Issue with JAR files when using a custom component

Anonymous — Sat, 16 Nov 2024 12:46:53 GMT

Hi we've developed a component to create online credit card payments (using payzen PSP solution)
see http://talendforge.org/exchange/index.php?eid=391&product=tos&action=view&nav=1,1,1
in this component we have some Jar files they are described in the xml file
pCreateMailOffer_java.xml
<CODEGENERATION>
<IMPORTS>
<IMPORT MODULE="PayementOfferV1a.jar" NAME="WSV3" REQUIRED="true"/>
<IMPORT MODULE="Signature.jar" NAME="Signature" REQUIRED="true"/>
</IMPORTS>
</CODEGENERATION>
and the Jar files are in the component zip
when running the jobs
see example http://code.google.com/p/payzen-components-for-talend/wiki/pCreateMailOffer_Exemple
There is an error unless the jar are copied in the \TOS-Win32-r63143-V4.2.2\lib\java\ directory
Did I miss something in my component design ?

Hello, I had the exact same issue with custom developed components.
Sometimes the jars are not copied automatically, it's probably a bug, the workaround is to copy them manually in the lib/java directory.
Moreover I am quite sure they are NOT copied if you create a new version of your jar with the same name an d the old one is already in the lib/java... the old file is not replaced.
I detected this at least in Linux, some colleagues installed the same component in windows and apparently the jar was copied for them.
We should probably open a bug in Jira for this

Hi Jruf
Put the jars in the component folder, and then declare the import in the XML descriptor file for example, tFileInputExcel_java.xml

	<CODEGENERATION>
		<IMPORTS>
			<IMPORT NAME="Java_Excel" MODULE="jxl.jar" UrlPath="platform:/plugin/org.talend.libraries.jexcel/lib/jxl.jar" REQUIRED_IF="(VERSION_2007 == 'false')" />

			<IMPORT NAME="geronimo-stax-api" MODULE="geronimo-stax-api_1.0_spec-1.0.jar" UrlPath="platform:/plugin/org.talend.libraries.apache.axis2/lib/geronimo-stax-api_1.0_spec-1.0.jar" REQUIRED_IF="(VERSION_2007 == 'true')" />

In case of having trouble with jars in user components:
It depends on the way how to get the studio your component.
In case you use the Component designer perspective and use the function Push Component to Palette: I this case: use this function more than once, I do not know why but only once does not deploy the jars not correctly.
At first find your component in the user component folder.
You can put your component also be hand in this folder and in this case open the Preferences->Talend->Components and click on Apply. Now the components from this folder will be copied and the Generation Engine starts again. This works only once. If you want to do this a second time you have to restart the studio.
In case of studio does not "want" your jar, please close studio, delete the file ComponentCache.javacache in the configuration sub dir in your studio and start studio again. This delete causes a rescan of all libraries and mostly they find now your jars also.
