IOException due to missing javac compiler


If you get the following error when using tWebservice component, it is because the CXF tools need javac to compile the generated source files.

[ERROR] IOException during exec() of compiler "javac". Check your path environment variable.
14 févr. 2011 14:00:32 org.apache.cxf.endpoint.dynamic.DynamicClientFactory createClient
GRAVE: Could not compile java files for file:/C:/DOCUME~1/services/LOCALS~1/Temp/wsdl1297688430389/ChainePartenaireJarWebServices/services/mainWSDL.wsdl.
Exception in component tWebService_2

So an Oracle JDK is required to use tWebservice component, as specified in the tWebservice documentation.



To fix this issue, follow these steps:

  1. Add JDK installation path\bin to the PATH system variable, for example C:\Program Files\Java\jdk1.6.0_20\bin. For more information, refer to How do I set or change the PATH system variable?
  2. Restart Talend Studio if the Job is executed in the Studio. Ignore this step if the Job script is scheduled to run out of Talend Studio.
