How to get Efficient Support

Getting prompt and efficient support from ZK

When you run into an issue in ZK, following this document can help you to provide the support team with informative data, thus speeding up the investigation and get prompt and efficient feedback. Here is a sample screenshot of an error. However with only a screenshot, it is difficult for the support team to find enough clues and provide timely support. Instead of providing a screenshot, please follow the tips and instructions below when submitting your issue.

Provide Sufficient information

Providing sufficient information helps us support you more efficiently.

The Sufficient Information Includes:

1. the complete server-side error or the client-side error (if any)
2. complete exception stack trace (if any)
3. A reproducible sample (please read #Tips for creating a reproducible sample
4. Precise and clear steps to reproduce the issue
5. ZK version and edition

   e.g. ZK 9.0.1 PE

6. Browser and its version

   e.g. Firefox 60

7. If it is hard to create a sample, you can provide an URL so that the support team can access it. When providing this URL, remember to turn on the js debug in your zk.xml.
8. Application servers (e.g. JBoss 6, if it's necessary).
9. If your case happens only in your specific environment, it is recommended to request an online meeting or provide a virtual machine as a copy of your actual environment,

Tips for creating a reproducible sample

You can:

1. Use zkfiddle
2. Zip your maven project with pom.xml and include necessary source code
3. Provide zul and its related Java source
4. Provide a public URL that we can visit

• Clone the original zul with the issue, remove irrelevant components
• You could move your Java codes (mostly event listeners) into <script>
• Replace your database data with static sample data in order to run without a database.

If you cannot provide a reproducible sample

Snapshot the error, request and response with Browser. Remember to turn on js debug in your zk.xml

<client-config>
	<debug-js>true</debug-js>
</client-config>

Please follow the instructions below and provide the support team with corresponding debug information.

Chrome

• Enable "Developer tools" by F12

Server side error	1. Request 2. Response

How to Run a Sample Maven Project

In order to narrow down the problem and eliminate differences caused by different environments, we often send you a sample maven project that tries to simulate and reproduce your issue. To run the project, you need to download maven and setup first.

1. Run your command line interface
2. switch to the sample project's root folder that has a pom.xml
3. Start jetty server with the command below

   mvn jetty:run

4. Visit the project's pages with your browser

If you don't know the zul's path or if the path is incorrect, just visit http://localhost:8080. A browser will show a link with the correct context path:

Click the link and it will list folders then you can navigate to find the zul.
