Hi,
Recently I followed the tutorials on creating plugins for Taverna 2. I
managed to develop a plugin for uploading large files to a Tomcat server.
The server contains a REST service developed with the Jersey API, where the
post method is used for uploading.The Taverna plugin contains user-side
(client) code which is directly dependent on jersey-client, jersey-core,
jersey-multipart, mimepull. I got the following questions/notes regarding
the plugin:
1: When invoking the service (plugin) the following error occurs:
java.lang.NoClassDefFoundError: javax/ws/rs/core/MultivaluedMap. This seems
to be an indirect dependency used by Jersey. I do not understand why this
class is not available even though the jersey-core package contains this
specific class. Looking at the /home/user/.taverna-2.4.0/repository/ folder
on the client side I am able to see the packages specified in the pom.xml
of the Maven plugin project. I also added the javax-ws.rs-api as an
dependency to the pom.xml but this does not solve the issue.
2: Running the TavernaWorkBenchWithExamplePlugin.java does not give the
NoClassDefFoundError and works perfectly.
3: I developed another plugin for downloading large files successfully.
This service is dependent on jersey-client. I added the jersey-bundle which
contains the jersey-client package as a dependency to the pom.xml. This
dependency seems enough to make the download plugin work.
4:Regarding the previous notes I am not able to solve this dependency issue
for the upload plugin. Am I missing additional dependencies or else why is
Taverna not able to locate the MultiValuedMap class ? The attachment of
this mail contains the pom.xml of the Uploader-activity. I also tried
adding the same dependencies in the pom.xml of the parent project
(Uploader) but to no avail.
Cheers,
Sidney
