Hallo everyone, we started working with jasperreports and use the jrs-rest-java-client libraries to create our reports. We now stumbled across a problem using an java.util.ArrayList as a parameter within an IN-clause: select *from tablenamewhere$X{IN, tablename.columnname1, pListParameter}and tablename.columnname2 = $P{pAnotherParameter}[/code]It works fine with the default expression for the pListParameter in jaspersoft Studio new ArrayList(Arrays.asList(new String[]{"Smith","Miller","Bush"}[/code]So the report uses the correct IN-clause and therefore the parameter. Now when i try to pass an ArrayList in Java (using the above mentioned jrs-rest-java-client library), single parameters get passed fine, but the ArrayList is not working. Part of the java code is: import com.jaspersoft.jasperserver.dto.common.PatchDescriptor;import com.jaspersoft.jasperserver.dto.resources.ClientReportUnit;import com.jaspersoft.jasperserver.jaxrs.client.core.JasperserverRestClient;import com.jaspersoft.jasperserver.jaxrs.client.core.RestClientConfiguration;import com.jaspersoft.jasperserver.jaxrs.client.core.Session;import com.jaspersoft.jasperserver.jaxrs.client.core.enums.AuthenticationType;import com.jaspersoft.jasperserver.jaxrs.client.core.enums.JRSVersion;import com.jaspersoft.jasperserver.jaxrs.client.core.enums.MimeType;import com.jaspersoft.jasperserver.jaxrs.client.core.operationresult.OperationResult;//code shortened... private String parametername = ""; private List<String> parameterMap = new ArrayList<String>();//code shortened... System.out.println(parameterMap.toString());//this does print out [smith, Miller, Bush]//reportPath is the URL for the report inside the jasperserver//format is e.g. PDF OperationResult<InputStream> result = session .reportingService() .report(reportPath) .prepareForRun(format.toUpperCase()) .parameter(parametername, parameterMap) .run();[/code]Does anyone have an idea where to look? Is there a way to log the resulting query string in jasperserver? Thanks in advance! Greetings, Philipp
