Upgrade to 6.7: Cannot find class [org.springframework.web.servlet.view.json.MappingJackson2JsonView]

[wodge]

Hi,

I've read the FAQs after trying to run my plugin against the 6.7 server (running in my local development environment). I have a problem that I believe is identified in the FAQs, but don't know how to solve it. There is some advice how to solve it, but I really need it to be spelt out so I can apply the fix.

The problem is as follows (from the FAQs):

Issue: MappingJacksonJsonView removed from Spring Framework Symptom: java.lang.ClassNotFoundException: org.springframework.web.servlet.view.json.MappingJacksonJsonView

Explanation: MappingJacksonJsonView has been replaced with a newer class.

Solution: Use org.springframework.web.servlet.view.json.MappingJackson2JsonView in bundle-context.xml file. Note: MappingJackson2JsonView imposes dependencies on additional Spring packages.

I need to know exactly what to add to the bundle-context.xml file please?

I've tried this:

<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"> <property name="contentType" value="application/json"/> </bean>

but I still get the same error... Could you please state exactly what code needs to be added?

Many thanks,

Warren

Hi Warren,

Thank you for your feedback.

If your "MappingJacksonJsonView" bean is inside "<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">", you can delete the whole "ContentNegotiatingViewResolver" bean.

Please, try this out and share the outcome.

Best Regards,

Denis

Hi Denis,

Thank you for your reply.

I'd actually been editing the bundle-context.xml in the server-side of the plugin, rather than the ui code... I solved the problem by following the FAQ guidelines in the section: "Upgrade to use content negotiation based on the "Accept" header of the HTTP request in a backward compatible way". I was then able to upgrade the plugin successfully. I didn't realize it was to be applied in the server-side code before then.

Many thanks,

Warren

Can you please share the changes done, I am facing the same issue.

DO we need to add any additional lib for MappingJackson2JsonView.

Thanks

Hi Vaibhav87,

The changes I carried out are as follows:

1. In the service code, change the MANIFEST.MF file so that in the "Import-Package" sections all versions are removed, except for those libraries I have explicitly added.  Here's my section, below:

Import-Package: com.vmware.vise.data,

com.vmware.vise.data.query,

com.vmware.vise.data.uri,

com.vmware.vise.usersession,

com.vmware.vise.security,

com.vmware.vise.vim.data,

com.google.gson;version="2.3.1",

javax.servlet.http,

javax.net.ssl,

org.springframework.beans.factory.annotation,

org.springframework.beans.factory,

org.springframework.stereotype,

org.springframework.web.client,

org.springframework.http,

org.springframework.web.bind.annotation,

org.springframework.util,

org.springframework.http.client,

org.apache.http.conn.ssl;version="4.3.3",

org.apache.http.client;version="4.3.3",

org.apache.http.impl.client;version="4.3.3",

org.springframework.beans,

org.springframework.beans.factory.config,

org.springframework.web.accept;resolution:=optional

(I introduced com.google.gson and org.apache.http.* so these have their own versions).

2. Followed the instructions in the FAQs:

https://vdc-download.vmware.com/vmwb-repository/dcr-public/5e6f0e2e-1e80-4128-b1b7-fbe3a4f58108/4a82...

Section "Upgrade to use content negotiation based on the "Accept" header of the HTTP request in a backward compatible way"

3. In order to be able to build, I also downloaded the two jar files:

Maven Repository: org.springframework » spring-beans » 4.3.9.RELEASE

Maven Repository: org.springframework » spring-web » 4.3.9.RELEASE

I added these to the libs directory, at: ${VSPHERE_SDK_HOME}/libs/

I updated the build-java.xml file so that within the <classpath> entity, I added two more path elements:

<classpath>

     <pathelement path="${VSPHERE_SDK_HOME}/libs/spring-beans-4.3.9.RELEASE.jar"/>

     <pathelement path="${VSPHERE_SDK_HOME}/libs/spring-web-4.3.9.RELEASE.jar"/>

</classpath>    

... These are the changes that were made and I now it builds from the build-plugin-package.sh script in the tools directory (of the ui code). I don't have the Jackson issue reported. The plugin works for both 6.5 and 6.7 H5 (as well at 6+ Flex).

Hope that helps you to progress.
