请教一个FOP/pdf 的问题

michaellucad(michaellucad)
fop 0.92beta.

程序大多数时候正常，但有时会出Exception, 1 of 20+... 见下面：

ERROR com.abc.gdp.tecp.eps.actions.PrintAllAction [-2087236473] - java.lang.IllegalArgumentException: The number of this PDFNumber must not be empty

SystemID: file:///usr/bea/home/beadtp4/config/dp4/tecp/config/conf/fop/fax-mail.xsl; Line#: 66; Column#: 93

javax.xml.transform.TransformerException: java.lang.IllegalArgumentException: The number of this PDFNumber must not be empty
at org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2344)
at org.apache.xalan.templates.ElemLiteralResult.execute(ElemLiteralResult.java:710)
at org.apache.xalan.templates.ElemApplyTemplates.transformSelectedNodes(ElemApplyTemplates.java:425)



Xsl 出错那行：
<fo:page-sequence master-reference="Section1-ps" initial-page-number=“1”>

感觉是哪个Fop class is not thread safe....
还是itext 好。。。可老板不给用。。。
求救！

      As you got the excpetion is:

      java.lang.IllegalArgumentException: The number of this PDFNumber must not be empty.

      The definition in the Line#: 66; Column#: 93 of fax-mail.xsl, its value must be validated in your object which you will pass to FOP. As you defined it (Section1-ps) initial-page-number=“1”>.
      • Thanks for trying to help, but I tried before, doesn't work. The REAL question is why it just works SOMETIMES, quite seems a non-thread-safe problem. -michaellucad(michaellucad); 2006-8-21 (#3157187@0)
        • Use try ... catch to catch the exception and write the object's status to log file. When you get exception, you can check log file for detail information. -insomniaca(insomnia); 2006-8-21 (#3157686@0)
          • well. it is hard to log status, since fop use Xalan, xmlapi... and exception thrown from xalan, but message is from fop.I think there must be something not thread-safe in fop. -michaellucad(michaellucad); 2006-8-22 (#3158518@0)
