关注使用BATIK的许多问题和答案,我无法修复我的错误,我找不到任何可能有用的东西.这个问题没有答案.
我的问题是当我在我的应用程序上下载pdf时,出现错误(我甚至尝试包含jar):
java.lang.ClassNotFoundException: org.apache.batik.dom.svg.SVGOMDocument
在我的碧玉报告中,我有这个包括:
<image>
<reportElement x="453" y="117" width="246" height="115"/>
<imageExpression class="net.sf.jasperreports.engine.JRRenderable"><![CDATA[net.sf.jasperreports.renderers.BatikRenderer.getInstance(new java.io.File("C:\\Project\\myProject\\web-app\\images\\tomcat.svg"))]]>
</imageExpression>
</image>
基本上,我的BuildConfig.groovy是这样的:
inherits("global") {
excludes 'xml-apis', 'xml-apis-ext', 'xercesImpl'
}
和我的依赖:
compile("org.apache.xmlgraphics:fop:0.94",

为什么我无法下载？svg无效？我从wiki 获得了这个 svg.
我上传一个音频文件> 10s时遇到问题并给我这个错误:
WARN:oejh.HttpParser:qtp1359061041-19: badMessage: java.lang.IllegalStateException: too much data after closed for HttpChannelOverHttp@7fd0cbe{r=5,a=IDLE,uri=-}
如果我上传音频文件<10s就可以了.
我搜索谷歌,但我找不到任何解决方案.这有什么解决方案吗？

每当我运行这个猪脚本
raw_data = LOAD'ample_data.csv'使用PigStorage(',')AS(
listing_id:chararray,fname:chararray,lname:chararray);STORE raw_data INTO'hbase:// hello_world'USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('info:fname info:lname');
日志告诉我这个:

这似乎没问题,但10分钟后,这个错误告诉我:

我不是这意味着什么,我的xml svg(在xml验证器网站上)是有效的代码.我写的是这样的:
file.write('<?xml version="1.0" encoding="UTF-8"?> \n'
+ '<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG …由于许多错误,我无法弄清楚为什么在没有将datanode slave vm连接到我的主vm时发生这种情况.任何建议都是受欢迎的,所以我可以尝试一下.首先,其中一个是我的slave vm日志中的错误:
WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Problem connecting to server: ubuntu-378e53c1-3e1f-4f6e-904d-00ef078fe3f8:9000
因此,我无法在我的主vm中运行我想要的工作:
hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar pi 2 5
这给了我这个错误

或者我错了？任何信息都会有帮助.
这很难解释.我需要一些我喜欢并保存的Coreldraw填充SVG.当Coreldraw中救了我的SVG,我叫了一个文件夹soil_Images与soil_ImgID1.png内soil.svg.我把web-app/images项目放在里面.由于某种原因,图像png未显示.
我在我的gsp中有我的svg:
<image x="177" y="76" width="36" height="23" preserveAspectRatio="none" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="/projectName/images/soil.svg"></image>
我soil.svg有另一个图像标签,显示我想要的真实图像:
<image x="44" y="29" width="8156" height="11707" xlink:href="soil_Images/soil_ImgID1.png"/>
我尝试添加的contextPath,如:${application.contextPath}/images/soil_Images/soil_ImgID1.png.
那没用.我错过了什么？
从搜索中,我发现了这个问题,并且按照说明我遇到了同样的问题.

如何将此列表转换为地图？
def list = [[10, STOREA, NORTH], [9, STOREB, CENTER], [11, STOREC, CENTER]]
喜欢：
def map = [['NORTH': ['STORE': 'STOREA', 'QTY': 10]],['CENTER': ['STORE': 'STOREB', 'QTY': 9],['STORE': 'STOREC', 'QTY': 11]]
我开始逐一进行list.each并添加一个新参数，但没有成功
什么是交易简单的解释或示例？即使阅读文档,我也完全不理解.如果我放transactional = true,我可以回滚,如果有任何错误,否则,如果transactional = false,意味着我不能回滚？
