Unable to deploy flowable WARs to Jetty Server

Flowable Engine
1

Hello,

I am Unable to deploy any flowable war file into Jetty server. I have copied all WAR files into webapps folder and ran the server, It is showing error like “Unable to find the main class to restart”. Do i need to do any specific configurations to deploy in Jetty. I am able to deploy WAR files into Tomcat without any issues. Kindly help me on this.

Thank you,
Srikanth

Hey Srikanth,

Which version of Flowable have you tried to deploy? And which version of Jetty are you using?

Cheers,
Filip

Thanks for this @srikanth.gandrakota.

I managed to reproduce this. The problem is spring-boot-devtool being part of the libs. I have opened issue flowable/flowable-engine#1389 to track this.

For the time being you would need to patch the wars so you can run them on jetty. You can do this with:

zip -d flowable-admin.war WEB-INF/lib/spring-boot-devtools-2.0.5.RELEASE.jar
zip -d flowable-idm.war WEB-INF/lib/spring-boot-devtools-2.0.5.RELEASE.jar
zip -d flowable-modeler.war WEB-INF/lib/spring-boot-devtools-2.0.5.RELEASE.jar
zip -d flowable-task.war WEB-INF/lib/spring-boot-devtools-2.0.5.RELEASE.jar

The flowable-rest is not affected as that one does not have the spring-boot-devtools packaged.

Cheers,
Filip

The fix for this is in master now. The next release of Flowable won’t have the same issues on jetty

Thanks alot. That helped me and now i am able to deploy.
