          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: general

        ReportedBy: a.jewall@web.de


hello, i have been working on this project and wanted to execute FOP from my 
java application and it stalls when it is executed.

it only works when i...
1.) 
execute it like this:
Runtime.getRuntime().exec("java -cp jars" +File.separator+ "fop.jar;jars" 
+File.separator+ "batik.jar;jars" +File.separator+ "xalan.jar;jars" 
+File.separator+ "xerces.jar org.apache.fop.apps.Fop temp" 
+File.separator+ "make_pdf.fo " +target_file.getText());
and after having a piriode of time in between where it does nothing.
it takes up to ten times as long as when it is executed by the batchfile
and it works perfectly from a batchfile
2.)
execute it like this:
Runtime.getRuntime().exec("java -cp jars" +File.separator+ "fop.jar;jars" 
+File.separator+ "batik.jar;jars" +File.separator+ "xalan.jar;jars" 
+File.separator+ "xerces.jar org.apache.fop.apps.Fop temp" 
+File.separator+ "make_pdf.fo " +target_file.getText()).waitFor();
and i close the window and with it the main programm and then all of a sudden 
it finishes and i get the pdf

either one is not very fine.
i need waitFor() with it and i cannot close the programm
i doubt that it lies within my programm because it is just one of many runtimes 
and it is the only one that doesn't work
