OWS uses different code from Oracle JWS hence will behave differently.

We have tried to improve download and it happens in parallel. deployment.cache.parallelDownloadCount will increase the number of download threads. Default is 6. Do you see the download dialog with progress bar for each jar?

Hi, Which version of OWS are you using? Which version of Java is being used to run the Jnlp app? Can you please send us the log files? You can enable logging : https://openwebstart.com/docs/OWSGuide.html#_logging . Also switch on log content of Jnlp file. In the stack trace there are several missing...

If you cannot sign with non-MD5 certificate and you do not want to touch JVM security then the only option is to run this particular jnlp app with OWS such that OWS ignores certificate issues. This can be done by specifying the deployment property deployment.security.itw.ignorecertissues =true and r...

n order not to lower our java distribution security level, is it possible "in some way" act on OWS configuration? Are there any other alternatives? So you don't want to touch the security of your JRE but you still want to run the Jnlp app with MD5 signed jars with OWS using the same JRE? ...

Hi

Why are you specifying j2se version as "1.x"? Why not 11 or 11* or 11+?

OWS's Unattended Installer will make the file association but (as far as I know and tried) it will not override the existing UserChoice in the registry.

For the Installer command line options, please see https://www.ej-technologies.com/resourc ... tions.html

Thanks. Btw, which company do you belong to? Your registered email id seems to be a personal email id.

Stephan is right. The problem is while running the jnlp application. When I opened the logs earlier, somehow in my editor the last lines were as follows and hence I asked for jnlp content: [ITW-CORE][2022-02-15 16:50:02.431 EST][DEBUG][net.sourceforge.jnlp.JNLPFile] Parsing JNLP file location: file:...

On windows, if you had .jnlp file extension associated with Oracle JWS then the following Registry entry would exist: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.jnlp\UserChoice The above key will have attribute ProgId pointing to ProgId of Oracle JWS exe,...

Thanks for the positive feedback.

It would help if you can support us by buying paid support.

I tested with another program that tests if a class is on the classpath:

Which version of AdoptOpen are you using to run your Jnlp app?

Please provide a snippet and configuration which reproduces your issue.

We are happy to announce the release of OpenWebStart v1.5.2.

Please see https://github.com/karakun/OpenWebStart ... tag/v1.5.2

You are passing f ile:/C:/Users/bill/Downloads/ScannerWebStart.jsp as jnlp file to OWS javaws. What is the content of this jsp file or rather is this jsp returning a jnlp file? OWS expects a file in jnlp format. The log has the following: [ITW-CORE][2022-02-15 16:50:02.431 EST][DEBUG][net.sourceforg...

I ran the simple example with the config you provided without any problem.

Can you please modify the example program to reproduce the issue? For instance by using the feature of log4J that uses the PluginAliases class.

Thanks

Jnlp HAS href: Oracle JWS: : - Initially the "Start in" property of Desktop Shortcut is blank. - Change the property. - On running the Jnlp again, JWS overwrites the desktop shortcut link file making the "Start in" property blank. Thus any change in "Start in" property...

If you specify absolute path e.g. c:\test for sys.installationDir then OWS will be installed there. If you specify relative path e.g. test for sys.installationDir then OWS will be installed in the specified directory relative to the directory where the unattended installer command is executed. If yo...

Can you please tell me what is the value of the property deployment.javaws.shortcut in your deployement.properties file?

Can you please confirm that for the same Jnlp file with the same deployment settings the desktop shortcut was not being created with OWS 1.5.0?

Thanks

If I delete this property the installation directory is sometimes in %USERPROFILE%\AppData\Local\Programs\OpenWebStart, but for some user it was in %USERPROFILE%\AppData\Local\OpenWebStart Probably this depends on whether the installer was run with admin rights and whether it was Current or All use...

Exception is below - log4j-core-2.17.1.jar and log4j-api-2.17.1.jar are in the jnlp and they are loaded. PluginAliases is part of the core-jar. Is this a known problem with OpenWebstart or AdoptOpenJDK? Old webstart is working fine? Can you please provide your Log4j2 config file or better still tak...

I created a minimal sample which works with OWS. <?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.0+" codebase="http://localhost:8080/jnlp"> <information> <title>Log4J</title> <vendor>Karakun AG</vendor> <offline-allowed/> </information> <security> <all-pe...
