Unable to launch a jnlp file

[jsa34]

Issue: When trying to start a JNLP file (launching), I come across the following issue:

javax.jnlp.UnavailableServiceException: uninitialized
	at javax.jnlp.ServiceManager.lookup(Unknown Source)
	at oracle.apps.fnd.formsClient.jnlp.FndFormsEngine.<init>(FndFormsEngine.java:53)

The JNLP is of type Oracle Forms: https://oracle-base.com/articles/11g/oracle-forms-11g-and-java-web-start
The JNLP file retrieved as a local file using:

SwingDriver.getSwingDriver("file:///C:/Users/test/Downloads/frmservlet.jnlp", true);

This then leads to...

Hello jsa34,

There are several exceptions pasted but most probably the cause is that you search for frame with title Oracle Forms:

Caused by: com.axway.ats.uiengine.exceptions.ElementNotFoundException: Unable to find frame with title 'Oracle Forms'
whereas later in the printed elements hierarchy it seems to be named differently (with '- Applet' at the end ):
Component hierarchy:
java.awt.Frame[name='frame0', title='Oracle Forms - Applet',

Note that ATS is using FEST-Swing library (org.fest.swing package, https://github.com/alexruiz/fest-swing-1.x) which is not recently updated. Also we have not tested with with applets so it might not be compatible.

Hope that helps!

[jsa34]

Yes - I could see this, however I have not set the expected window title - it seems to be self-derived when instantiating the SwingDriver

[svilen-d]

The windows title searched comes from the title defined in the JNLP file.
For more technical details you may check the source of com.axway.ats.uiengine.SwingDriver.start() method for example. There ATS uses netx-hunson library to parse and start the app defined in the JNLP file.

[jsa34]

Ah - Apologies, I really should have looked at the source... I was just going by the possible constructors, and it looks like it's just missing a constructor for setting the window title when setting the app type as JNLP.

I have done this by creating a custom class for instantiating the SwingDriver:

public CustomSwingDriver(String jnlpLocation, String windowTitle, boolean cacheEnabled ) {
    this.windowTitle = windowTitle;
    this.jnlpLocation = jnlpLocation;
    this.isJnlpCached = cacheEnabled;
}

But, when I try and use the inspector, it returns:

CustomSwingDriver cannot be cast to com.axway.ats.uiengine.internal.driver.SwingDriverInternal

[dslaveykov]

Hello,
could you provide a little bit more of the stack-trace.

[jsa34]

That's all I have:

java.lang.ClassCastException: com.test.driver.CustomSwingDriver cannot be cast to com.axway.ats.uiengine.internal.driver.SwingDriverInternal
	at com.axway.ats.uiengine.engine.SwingEngine.useComponentInspector(SwingEngine.java:570)
	at com.test.DriverManager.createJavaDriver(DriverManager.java:96)

Custom constructor used:

package com.test.driver;

import com.axway.ats.uiengine.SwingDriver;

public class CustomSwingDriver extends SwingDriver {
    public CustomSwingDriver(String jnlpLocation, String windowTitle, boolean cacheEnabled) {
        super(jnlpLocation, cacheEnabled);
        this.windowTitle = windowTitle;
    }
}

Usage:

        String jnlpFileName = "test.jnlp";
        File jnlpFile = new File("C:\\Users\\Me\\Downloads\\" + jnlpFileName);

        String startWindowTitle = "Window Title";

        SwingDriver javaDriver = new CustomSwingDriver(jnlpFile.getAbsolutePath(), startWindowTitle, false);
        if (jnlpFile.exists()) {
            jnlpFile.delete();
        }
        SwingEngine swingEngine = javaDriver.getSwingEngine();
        swingEngine.useComponentInspector();

[jsa34]

I've raised a PR for the SwingDriver constructors that should resolve this (the ability to set the window title to something other than the default derived from the JNLP file)
