Good day, we just upgraded to Stimulsoft.Java so we can export PDF's and CSV from our backend service without needing external services.
However I just found out the HTML5 designer is packaged in an old format that's not even supported out of the box by our Spring Boot setup... (https://docs.spring.io/spring-boot/docs ... imitations)

I'm still looking into alternatives for our setup without changing too much in our deployment process.

Our frontend is a separate Vue-based PWA/SPA so it would be nice to be able just use the JS version for the designer without it being packaged inside JSP.
Or is there another way to serve the HTML5 designer in Spring Boot running with embedded Tomcat?

Hello

You can use iframe to embed designer into your application.

I would if I were able to properly integrate the designer into our Spring Boot application.
I tried following the Github sample for Designer+Spring Boot.

Currently getting the following error (when trying to view the designer page):

Code: Select all

org.springframework.data.redis.serializer.SerializationException: Cannot serialize
 ....
Caused by: org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer
 .... 
Caused by: java.io.NotSerializableException: com.stimulsoft.report.events.StiBeginRenderEvent

After some debugging it looks like it's trying to put that event into my session. It does not seem to work when Spring uses Redis for persisting sessions..
