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...

On line 308 In the Stage 2 log, OWS is Starting your application and invoking the main method of your application. After that there is an exception in your app: Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(...

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.

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/...

> Removing APPLICATION_TEMPLATE.JNLP seems to fix the issue, but I now have a new problem: My app (login prompt) is not launching before a POST is sent. The POST fails because user is not authenticated. > I don't understand. From where did you remove the APPLICATION_TEMPLATE.JNLP, from JNLP-INF in t...

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?

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...

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...

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...

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

What does your INDEX.LIST contain?

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?

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...

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? You are running on Windows OS which is not x86, other jvm args are picked up. Your jnlp is being launched wit...

OWS is not a replacement for Java 8. OWS uses a JVM (Java8 or higher) to start your application which is specified in a Jnlp file ( https://docs.oracle.com/javase/tutorial/deployment/deploymentInDepth/jnlp.html ) OWS implements https://jcp.org/en/jsr/detail?id=56 Your application must be packaged in...

Do you mean Auto Update of OpenWebStart? You can do it using itw-settings: DisableAutoUpdate.png The following properties in deployment.properties are set from the choice made in itw-settings: ows.update.strategy.launch=NEVER ows.update.strategy.settings=NEVER ows.update.activated=false > as i tried...

please post the complete stage 1 and stage 2 OWS log files.

> What exactly did the "javaws.exe -Xclearcache" command clear? I assumed it will get rid of all the cached data.

It clears the applications cache - all the cached jnlps and jars.

jvm-cache is for caching the downloaded jvms that are used to run jnlp applications.
