Error while trying to run a simple job

Anonymous — Sun, 20 Apr 2014 13:48:09 GMT

Hi,
I'm using the latest version of talend and I'm trying to do something simple:
Read an XML file which matches a schema, and print its rows with tLogRow.
I'm new to talend, and just to mention I've already managed to run a job with talend (which takes rows from DB and puts them out to a file).
I've attached my job image.
Unfortunately, I'm getting the following error when trying to run the job:
"
Execution failed : Failed to generate code.

Job FileRequest ended at 15:39 20/04/2014.
"

Forgot to mention:
1. I'm using jre7 within the talend open studio. (Though I have jre8 installed).
2. One more question:
How can I receive any file with XML extension ? (In tFileInputXML component I have to write a name of xml file).

Hi,
What's your XML file structure? Could you please paste it on forum?
Best regards

I have a feeling the problem is more deeper than that.. but here:
XML Schema:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Root">
<xs:complexType>
<xs:sequence>
<xs:element name='row' type='ActorType' minOccurs='0' maxOccurs='unbounded' />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="ActorType">
<xs:sequence minOccurs="0">
<xs:element name="actorid" type="xs:string"/>
<xs:element name="name" type="xs:string"/>
<xs:element name="pdf" type="xs:base64Binary"/>
</xs:sequence>
</xs:complexType>
</xs:schema>

XML File Input:
<?xml version="1.0" encoding="ISO-8859-15"?>
<root>
<row>
<actorid>1</actorid>
<name>PENELOPE</name>

Talend Version: 5.4.1
OS: Windows 7
Location: Talend library on my windows desktop
JAVA: I've installed JRE 8.0, but currently using 7.0 on my talend open studio

Yes, it appears JDK 1.8 does not play nice with Talend 5.3/5.4. If you still have this issue, install 1.8 and install 1.7 (restart your system between uninstall and install to force registry updates).

Hi,
Are there two JDK 1.8 and 1.7 in your PC? If so, could you please check your path variable to make sure JDK 1.7 value is set in front?
Best regards

Hi,
Sabrina, i've already checked the environment path (You can see in the image i've attached).
Maybe I should uninstall JDK 8.0 ? (Although everything is configured to JDK 7.0?)

Hi,
I think the problem is with input schema for pdf data type. Also you don't have schema for pdf in your job. Can you try creating a schema in repository and test the job.
<xs:element name="pdf" type="xs:base64Binary"/>
I used string for PDF, it works fine.
Thanks

Hi,
Don't think it is the problem because at first that schema and file didn't have any pdf and I still got that error.

Have you created a schema in repository for your xml input file?? Whether it displays data correctly in the preview?

Hi,
I'm getting : "Failed to generate code" on the preview of the schema.
I've attached the printed screen.
I've changed the encoding of the input file to UTF-8, and also chose UTF-8 encoding after xml file selection.

ohadtest1 - what jdk are you using? Failed to generate code seems to indicate you have an environment setup issue...
If you're using jdk 1.8, you need to downgrade to 1.7
See http://www.talendforge.org/forum/viewtopic.php?pid=133934#p133934
and read the responses that follow...

PROBLEM SOLVED!
Pay attention that even if you change "JAVA_HOME", java still can run from 1.8 library.
So make sure you write in command line: "java -version" to check what is the version that Talend works with.
After uninstalling JAVA 8, everything works fine. Changing paths isn't enough!
