Supported Browsers: ZK supports the latest stable versions of Chrome, Edge, Firefox, and Safari, as well as the latest stable iOS Safari and Chrome for mobile devices.
While modern ZK versions prioritize current web standards, older releases (ZK 7–9) maintain compatibility with various versions of IE as indicated in the table above.
ZK JDK Support9
ZK 8.6 and earlier versions require at least Java SE 6; ZK 9 requires at least Java SE8; ZK 10 requires at least Java SE11; they work with higher versions that are binary-compatible with the official Oracle JDK 1.6, 1.8, and 1.11 respectively. If you run into any ZK issues relating to Java upgrade please report to us.
Notes
-
1.Due to the technology or the 3rd party library used, the following components have limited support for responsive and tablet/touch devices: 3rd party-based components (ex. ZK JasperReport); ZK Calendar; ZK Pivottable; ZK Spreadsheet (Keikai) and ZK File Upload.
-
2.ZK Spreadsheet (Keikai Spreadsheet), ZK Pivottable, and ZK Charts are available as add-ons. They are not part of CE, PE, EE
-
3.Also refer to ZK vs JSF based Solutions Performance Report
-
4.ZK Fushionchart has now entered maintenance mode as of Q2, 2014 as the 3rd party library that it's based on - FusionCharts free, has moved out of flash and stopped supporting it.
-
5.Android native browsers may behave differently depending on the device it is on and its version.
-
6.ZK Studio and ZK Spreadsheet (Keikai) requires version 6.
-
7.ZK Timeline/Timplot has now entered maintenance mode as of Q3, 2014 as the 3rd party library that it's based on SIMILE Widgets, has stopped any activities.
-
8.This list demonstrates the supported browsers of ZK Framework. Other products such as ZK Pivottable and ZK Spreadsheet (Keikai) may support a different set of browsers. For detailed information please refer to each product's documentation.
-
9.ZK 8 and lower versions works with JDK 1.6 (and higher). ZK 9 works with JDK 1.8 and higher. However not all JDK features (e.g. Module System since JDK 9) are available. Please contact us if you are interested in any specific feature.
-
10.A certain components rely on modern technologies such as HTML5 and CSS Flex, these components will only work with modern browsers that are compatible with these new technologies and will not work with legacy browsers like IE9 and IE10. Please check Component Reference for details.
-
11.ZK provides a wrapper for developers to use Google Maps in ZK easily. Developers need to obtain their own Google Maps API Key.
