I am trying to create a new web service client and whenever I select it I get a null pointer error How do I fix this. I have a new wsdl I need to create the client for and it won’t do it.

From the log.

Crooks,

Sorry that you are seeing this problem.

1. Are you seeing the exception when you are selecting the New>Other>Web Services>New Web Service Client for your java project?

2. Can you please clarify if your project’s Java version is 9 or 10? We have a known issue with some of our WebService generation code when the project’s java version is 9 and above. As a workaround, please check if you can generate the client for a Java 8 or below project.

3. From the stacktrace it looks like there is a problem picking up the configured Websphere servers. Can you please let us know which version of Websphere is configured in the Servers view?

Apologies for inconvenience caused.

1. Yes that is what I am trying to do.
2. The project is set up to use Java 6, I did create a new project using java 7 and that did not work either.
3. I do not have a websphere server set up on my local machine, all our application are installed onto a server that uses websphere 7.0. I have never had to have a server set up before.

Barb,

Thank you for the details. I could not replicate the problem at my end with the latest MyEclipse 2018.9.0.

1. Can you please let us know your MyEclipse version details from Help > About MyEclipse section? If possible, please send us the zipped project to help us replicate the problem at our end.

2. Also share with us the screenshot of the IDE at the point where the exception is logged to help us get a visual.

3. Can you please switch to a new workspace and check if the problem persists. If yes, then send us the complete workspace log by clicking on the icon for ‘Export Log’ in the Error Log view, save it a .txt and attach it.

Version CL 2018.9.0 Build 16.0.0-20180903

When I created a new workspace it worked. Not ideal since I am really trying to update a current client with a new wsdl, but I can deal with it.

Barb,

I have filed a bug for the dev team to investigate the NPE. They will get back to you in case they need more information.

Apologies for inconvenience caused.

Barb,

On further investigation, it looks like the problem is with a non existent server being registered in the servers.xml that is located in your workspace dir/.metadata/.plugins/org.eclipse.wst.server.core/servers.xml.

Shut down the IDE and then edit the servers.xml, look for the non existent websphere entry, delete it, save the file and restart the IDE and check if you can create the new Web Service Client successfully. Before editing the servers.xml, please take a backup so you can revert back in case it doesn’t help.

If you are still seeing the issue, please share with us the workspace log file again to help us investigate further.

Please let us know how you get on with this workaround.

All I had to do was change the java version that is loaded on install from 10 to 8 and everything started working again. Thank you for your help.

[support-swapna]

Bard,

The fix for the NPE is out with our latest MyEclipse release, 2018.12.0.
Please update to the latest release from Help > Check for Updates and let us know how it works for you.
