碧玉报告在grails [英] jasper report in grails

问题描述

我使用jasper插件获取pdf格式的报告.我正在尝试使用此示例(http://grails.org/plugin/jasper)来获取报告.要获取以下代码所使用的pdf格式的特定ID信息.

I use jasper plugin to get report in pdf .I am trying to get report using this example(http://grails.org/plugin/jasper).To get particular id information in pdf format used below codes.

    <div class="buttons">
                <g:form>
                    <g:hiddenField name="id" value="${userManagementInstance?.id}" />
                    <span class="button"><g:actionSubmit class="edit" action="edit" value="${message(code: 'default.button.edit.label', default: 'Edit')}" /></span>
                    <span class="button"><g:actionSubmit class="delete" action="delete" value="${message(code: 'default.button.delete.label', default: 'Delete')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Are you sure?')}');" /></span>
                </g:form>
            </div>
            <g:jasperReport jasper="use" format="PDF" name="users">
<input type="hidden" name="id" value="${userManagementInstance?.id}" />
</g:jasperReport>

我在show.gsp页面中使用了上面的代码来获取特定的id报告.

I used above code in show.gsp page to get particular id report.

我在web-apps/report文件夹use.jasper中使用以上代码.

I use above code in web-apps/report folder use.jasper.

Error 500: Executing action [index] of controller [org.codehaus.groovy.grails.plugins.jasper.JasperController] in plugin [jasper] caused exception: null
Servlet: grails

Exception Message: invalid stream header: 3C3F786D 
Caused by: invalid stream header: 3C3F786D

At Line: [-1] 

但是我得到的错误是无效的流头:3C3F786D.因此，请指导我解决此问题.

But i am getting error that is invalid stream header: 3C3F786D. So please guide me to solve this problem.

推荐答案

似乎您正在使用.jrxml文件引用子报表.但是，您应该使用编译后的版本.jasper.

It looks like you are refering to the subreport using the .jrxml file. But, you should be using the compiled version .jasper.

我希望那行得通！
