Webservice datasource does not work after upgrading to jasperserver v8x

Problem Description:

Suppose you developed a jasperserver report using the webservice datasource package https://community.jaspersoft.com/wiki/installing-webservice-datasource.

You upgraded your jasperserver to v8x from v7x.  You are getting the following error when running the report.

2023-11-20T12:30:21,527 ERROR JRFillSubreport,pool-11-thread-69:961 [] - Fill 1: exception

net.sf.jasperreports.util.JacksonRuntimException: com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `com.jaspersoft.webservice.data.enumerations.LanguageType` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)

at [Source: (com.jaspersoft.jasperserver.api.metadata.common.domain.util.FileBufferedOutputStream$DataStream); line: 2, column: 230] (through reference chain: com.jaspersoft.webservice.data.WebServiceDataAdapterImpl["language"])

Workaround:

This problem is a result of migration of data adapter from Castor to Jackson happened in JR 6.19.0/JRS 8.1.

a) The webservice datasource package is a community contribution, it is not a part of the jasperserver product.  Therefore, it is not supported.  Jasperserver is subject to change without notice regarding unsupported third party components.

b) In this case, you can try the following workaround,

Download jasperreports-castor-6.20.0.jar from this link, https://repo1.maven.org/maven2/net/sf/jasperreports/jasperreports-castor/6.20.0/

Stop JRS, add the jar to WEB-INF/lib, restart JRS.
