Re: unable to launch jnlp File - Fatal: Read Error: Could not read or parse the JNLP file

In the Jnlp, your application is tagged as an Applet. OWS does not support applets. <applet-desc name="KeyLink Applet" main-class="com.ubs.swidKL2.v1.init.KLW" width="1260" height="850"> You will have to convert your applet to a java application and specify it...

Re: Launch Error: Could not launch JNLP file

Please attach the log files. Please don't copy and paste logs as it is difficult to read long logs.

It could be that the jar file is corrupt or you need to provide the jvm arg in jnlp for the module in which the class iss.

Re: Heapsize leads to abort of the OpenWebstart installation

You must be running the OWS installer for Windows. install4j creates a log file prefixed with i4j_log in the temporary directory when an installer application is executed. This log file can be helpful for debugging purposes. Also I found the following. See if it helps [url]https://stackoverflow.com/...

Re: Jars are downloaded several times during application running (and it fails)

You say the jars are downloaded and the application is started successfully but after that jars are downloaded again?

Can you please send the logs? What does your C:\Users\Janak\.cache\icedtea-web\cache\recently_used.cache look like?

Is your application using JNLP API like DownloadService?

Re: Application not launching - looks like looping behavior

But, are you using any of the JNLP APIs in your application? Is removing the APPLICATION_TEMPLATE.JNLP a solution? Don't you need Signed JNLP? How about removing JNLP-INF from INDEX.LIST but keeping the JNLP-INF/APPLICATION_TEMPLATE.JNLP? Does that work? OWS code is different from JWS of Java 8 so c...

Re: Slow startup - many jars

Just to clearly identify your issues: 1. When there are many files in the cache itw-settings is not able to clean the cache, you had to do it at OS level. This happened when you had 270 jars in the cache. How did you try to clean the cache, by selecting and purging files in "View Files" pa...

Re: Slow startup - many jars

Do you mean to say clearing cache with the itw-settings tool did not clear the cache? Also do you mean that App started faster when cache was clean and OWS downloaded resources against when the resources were in the cache? Is the app starting slow everytime when resources are present in the cache? I...

Re: Application not launching - looks like looping behavior

This is just the META-INF. What about the other content at root level?

What does your INDEX.LIST contain?

Re: Application not launching - looks like looping behavior

would you consider buying paid support or online consulting? Then I can have a deeper look at your app.

OWS is starting your app, but OWS is also finding something in your jar which is making it read the APPLICATION_TEMPLATE.JNLP again and again.

What is the content of your jar file?

Re: Application not launching - looks like looping behavior

Of course, you either have the APPLICATION.JNLP or the APPLICATION_TEMPLATE.JNLP. You have the latter. I tried creating a sample signed jnlp like yours. See attached. I could not reproduce your issue. In your case too the jar is processed, APPLICATION_TEMPLATE.JNLP is found and processed and then ap...

Re: Application not launching - looks like looping behavior

Can you share your APPLICATION.JNLP?

What are the contents of your jar i.e. the directory structure within the jar and contents of JNLP-INF and META-INF folder and manifest?

You have a jar file specified in your Jnlp file. This jar file must have a JNLP-INF folder which must contain APPLICATION.TEMPLATE.JNLP. Can you please send me the APPLICATION_TEMPLATE.JNLP?
