Displaying drop down menus

[Prabhu S]

Hi,

Our swing app as certain operations which involve choosing from drop down menus. An instance is as shown below. Its using our native standalone JAVA client. This drop down does not happen with Ajax. For example, clicking on the window "All Events" nothing happens. Any suggestions?

Server OS: CentOS 7

AjaxSwing version: 4.6.2

JDK version: 1.6

Hi!

For correct work on UNIX, you need to use AjaxSwing with either X-Window system or Xvfb.

Here is a step-by-step guide for setting up AJaxSwing for UNIX (in the next release this process will be more straightforward and clear) :

Before you start make sure you have Xvfb and zip packages installed.

1. Remove conf/lastKnownJdkVersion.txt if it exists.

2. Execute the following command

    chmod 777 bin/setup/setup.sh

    Run bin/setup/setup.sh

3. Start AjaxSwing, wait for a few minutes, then stop it.

4. Run bin/setup/setupForXvfb.sh

5. In bin/setEnv.sh replace 

    JAVA_OPTS="${JAVA_OPTS} -Djava.awt.headless=true"

    with

    JAVA_OPTS="${JAVA_OPTS} -Djava.awt.headless=false"

    In conf/default.properties set

    agent.usePlatformGraphicsEnvironment=true

6. Start AJS with the following command (it's just an example, don't start AjaxSwing like this each time)

    Xvfb :0 -screen 0 1920x1080x24 & ./startServer.sh

    or start Xvfb in the background before running AJS

It's better to execute Xvfb on server's startup and then just start AjaxSwing with ./startServer.sh

Hi Yevhen,

Thanks for the response. We followed the steps mentioned with Xvfb. But couldn't get the drop down menu working. Still see the same issue.

Hi,

The solution we provided in our previous email has proved itself as a reliable one, it should definitely work. If it doesn’t, the only reason is misconfiguration.

We can help you with configuring AjaxSwing to work with your app.
