Appeared this error immediately dizzy, because just contact Birt report, do not know from there, after Baidu and consult people, summed up the following solutions:

Because the company created the Birt report with a lower version of 2.6.2, I now use the 4.4.2 version, due to version inconsistencies caused by errors. Note the beginning of the report file:

<report xmlns = "http://www.eclipse.org/birt/2005/design" version = "3.2.23" id = "1">
     <property name = "comments"> Copyright (c) 2006 << here is the name of your company >> </ property>
     <property name = "createdBy"> Eclipse BIRT Designer Version 4.4.2.v201410272105 Build <4.4.2.v20150217-1805> </ property>

The value of the report node's property version is: 3.2.23, when I use the Birt version of 4.4.2 (version corresponds to 3.2.23), and the company uses 2.6.2 (version corresponds to 3.2.22), only need to change the value of version to the lower version of the line (3.2 .22) on the line, but it is recommended to modify the Name= "CreateBy" of the property node text value (this fix does not change the error), to the previous text value (modify the Birt report file before the proposal to save the value first), to avoid confusion. The following changes are followed:

<? xml version = "1.0" encoding = "UTF-8"?>
<report xmlns = "http://www.eclipse.org/birt/2005/design" version = "3.2.22" id = "1">
     <property name = "comments"> Copyright (c) 2006 << here is the name of your company >> </ property>
     <property name = "createdBy"> Eclipse BIRT Designer Version 2.6.2.r262_v20110209 Build <2.6.2.v20110214-1523> </ property> 

These changes should be modified according to your own situation, which is only for my own example.
