Dear All, I have created a custom theme and I could see the changes reflecting in preview. I also generated a JAR and added to classpath however I still do not see the new changes especially related to new colors added under Plot of custom theme. 1) Could anyone please tell me, how would I apply my recent colors part of newly created Custom theme to my report within Jaspersoft Studio. 2) After #1, please tell me same how would I see in Jaspersoft server, here, I uploaded the Jar file and also set as Active Theme but still no luck. Up on my research, all I see is below, To use the chart theme in Jaspersoft Studio, you must add the JAR to your project's classpath: in the Project Explorer, right-click the JAR and choose Build Path > Add to Build Path. If you're Project Explorer isn't displayed, click Window > Show View > Other > Project Explorer. Once Jar is uploaded, you can use the repo: syntax in a report to specify this JAR as your chart theme. Any guidance is greatly helpful.
