Java Web Start version of Jalview fails with error 'Unable to Launch - because JAR resources in JNLP are not signed by same certificate'


Thank you to everyone who wrote letters of support last year for our application to the BBSRC, we should hear the outcome in the next couple of months.

We are now applying to the Wellcome Trust to renew funding to support Jalview's use in biomedical sequence analysis, including interpretation of genomic variation and long read RNA data (e.g. Nanopore) at the protein coding level. If you would like Jalview to continue to develop and be supported then please take a few minutes to write us a support letter saying how you use Jalview in your research/teaching.

Write as a PDF including your institution's heading and send to:
support_jalview@bartongroup.org by Friday 22nd March 2019.

Thank you!

This error (and others like it) is raised when an old version of the Jalview Webstart JNLP is being used to launch the latest version of the application (for instance, because you have created your own JNLP file in order to increase the memory available to Jalview).
To fix, first make sure that you are using the latest version of the Jalview JNLP file (right-click or apple-click to save this link to a file) to launch jalview.

If you are using the latest version of the JNLP then you need to open the Java Web Start console panel, and flush any application caches and remove any old versions of Jalview listed in the application viewer. To do this:

  1. Locate and open the java console on your system (in your control panel or systems settings, but may also be in the Utilities section of the Applications folder on OSX.
    If you have access to a terminal, you can usually open the console with
    javaws -viewer
  2. Locate any jalview instances in your applications cache and remove them (usually, select the application and hit the delete or 'X' button)

Once you've cleared the cache, try to run the Jalview JNLP file again.
