我使用jasper插件以pdf格式获取报告。我正在尝试使用此示例(http://grails.org/plugin/jasper)获取报告。要获取以下代码使用的pdf格式的特定ID信息。
<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页面上使用了上面的代码来获取特定的id报告。

我在web-apps / report文件夹use.jasper中使用上面的代码。
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

但是我收到的错误是无效的流标题:3C3F786D。 所以请指导我解决这个问题。
答案 0 :(得分:1)
看起来您正在使用.jrxml文件引用子报表。但是,您应该使用已编译的版本.jasper。
我希望有效!
