Hi,
I encountered another problem while working with TOS. For my JavaFlex-Code I need to import four *jars and a bunch of dependencies. I thought that it may be solved by putting all *.jar into <TOS installation path>/lib/java and putting a tLibraryLoad component with import-statements in the job.
This did not work, so I checked the path for external libs in perferences. Everything is fine it points to <TOS installation path>/lib/java.
So I tried to load every *jar with tLibraryLoad this only works for one component, after the second and third one is added nothing works anymore. And only the last added *.jar is recognized.
Something like this:
---onSuccess OK ----> ---onSuccess OK ----> --- onSuccess OK ----> ...
I beginning to get crazy. Maybe I should program it all by-hand as my dearest consultant ;-).
Thanks for the reply. Is there another way to provide TOS with external libs? I tried to put the jars in the lib/java folder of Talend Open Studio, created a separate user lib in perferences or added a classpath variable there. But after even restarting TOS the classes in that external lib are not resolved. How do you import external libs to a job?
Hi,
I saw that the bug is resolved. So I tried to download the source for building the responsible class (org.talend.librariesmanager.model.ModulesNeededProvider). But somehow it does not work I get an error from TOS:
An internal error occurred during: "Initialisierung der Generator-Engine wird durchgeführt...". Unresolved compilation problems: ModuleNeeded cannot be resolved to a type Missing code implementation in the compiler
My question is, can someone provide me a nightly build or a intermediate binary from TOS. It would be enough if someone could give me a right compiled version of ModulesNeedeProvider.
Any other workaround would be also appreciated.
My workaround was to exit the Studio after adding each new library. The start it again and add another. I had to do it for most of the libraries, but some got added ok.
Now I finally added them all and after another restart this thing actually runs
Hi,
I tried for the first time to use this component with 2 jars, but it seems to work quite randomly (with TOS 3.0.1) and I face the same symptoms (jar is copied to <TOS installation path>/lib/java, but does not appear in the .classpath, or appears and disappears at random, and org.talend.fileprocess cannot not found). Is this issue really fixed?
As a workaround, I tried to put the sources of the jars I use in the project, but I cannot figure out what is the right place to do this (if such a place exists). It works if a put them in .Java/src, but of course they are removed when the project is closed?
By the way, it looks that tLibraryLoad does not work for Job building, but works for runtime dependencies. Indeed I only had to put the source of the package I use directly from the job, but not the dependancies of that package.
Also, wouldn't it be much simplier if there was a directory to put jars in each project, and all jars in that directory would be added to the classpath automatically? Better have too much libs at build/run time than have classpath problems? Once the job is exported, the superfluous jars might still be removed.
How do we use external jars in Talend? I am writing functions that use external jars, not able to figure out how to set the external jars in classpath or libraries.
