Running jrxlm report with Jasper Server

I have created jrxml report by iReport. Then I have run it with JasperServer and it work perfectly. I have generate pdf report by this URL:

http://localhost:8081/jasperserver/flow.html/flowFile/my_report.pdf

It works well but when I tried to refresh the page I get this error: 

An id is required to lookup a FlowDefinition

Also when I try to call this REST service in JasperServer client application I get this error:

com.sun.jersey.api.client.UniformInterfaceException: Client response status: 500

This is the Java client application to call the REST service:

public final static String serverUrl = "http://localhost:8081/jasperserver/flow.html/flowFile/my_report.xls";
public final static String serverUser = "jasperadmin";
public final static String serverPassword = "jasperadmin";

static File outPutDir= new File(System.getProperty("java.io.tmpdir"));

public static void main(String[] args) {
    try {
        Report report = new Report();
        report.setUrl("/reports/samples/Employees");
        report.setOutputFolder(outPutDir.getAbsolutePath());
        JasperserverRestClient client = JasperserverRestClient.getInstance(serverUrl, serverUser, serverPassword);
        File reportFile  = client.getReportAsFile(report);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
Solution

  • flowId

    When calling flow.html you must provide an action, which is put into the flowId. JasperServer is using the flow.html to provide an interface which can be accessed over the URL. For example if calling a report this would be:

    _flowId=viewReportFlow

    Also the report and parameters have to be provided. So with this in mind the URL could look like this:

    http://localhost:8081/jasperserver/flow.html?_flowId=viewReportFlow&reportUnit=/reports/samples/Employees&j_username=the_user&j_password=secret&output=pdf

    Server error

    When connecting to the server, this URL is used

    http://localhost:8081/jasperserver/flow.html/flowFile/my_report.xls

    This is not the server URL used by JasperserverRestClient. The server URL should look like this:

    http://localhost:8081/jasperserver

    NOTE: flow.html is for accessing JasperServer without logging into the UI. It is not an application path where you should put your reports.
