jasper grails報告

Question

我使用jasper插件來獲得pdf格式的報告。我試圖使用這個例子獲取報告（http://grails.org/plugin/jasper）。要獲得以下使用的pdf格式的特定id信息碼。

<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頁面中使用了上面的代碼來獲取特定的id報告。

    <summary>

    </summary> 
</jasperReport> 

我在web-apps/report文件夾中使用上面的代碼use.jasper。

Error 500: Executing action [index] of controller [org.codehaus.groovy.grails.plugins.jasper.JasperController] in plugin [jasper] caused exception: null 
Servlet: grails 
URI: /inventoryManagment/grails/jasper.dispatch 
Exception Message: invalid stream header: 3C3F786D 
Caused by: invalid stream header: 3C3F786D 
Class: Unknown 
At Line: [-1] 

但是我得到的錯誤是無效的流頭：3C3F786D。 所以請指導我解決這個問題。

Answer 1

看起來您正在使用.jrxml文件引用子報表。但是，你應該使用編譯版本.jasper。

我希望工程！
