Top Forums Shell Programming and Scripting Segmentation Fault(Core Dump) Error Post 302442181 by mick_000 on Tuesday 3rd of August 2010 01:14:01 PM

Hi,

I didn't try running any debugger. I will just describe the problem in detail. I have some 20 odd xls files which has some data in it. The filesize is less than 600KB put together. I have an unix script that will iteratively pick one file at a time and then call a java pgm which will perform some operations n write a output text file.

Given below is the code snippet:

Code:
FILES="*"
for file in `ls $FILES`
do
java -Xms512m -Xmx512m -classpath "-jars" javaFile $file        --Line NO 4
done

am passing the filename to the java pgm for performing some operations. Out of the 20 odd files , till the 9th file the whole pgm runs perfectly after which for each file i am getting an error in Line No.4 saying "Segmentation Fault(Core Dump)". I am running this script in unix server.

I tried executing a script file tat takes an input file size of 30MB and tat generates an output file of same size. The execution went well and i got no segementation fault for this scenario.

But in the case of less file size am getting this error. Can someone suggest an idea?

Thanks in advance.

schemagen

schemagen(1)						      General Commands Manual						      schemagen(1)

NAME

       schemagen - Java(TM) Architecture for XML Binding Schema Generator Specification Version: 2.0
       Reference Implementation (RI) Version: 2.0 ea3

   Launching schemagen
       The schema generator can be launched using the appropriate schemagen shell script in the bin directory for your platform.

       The current schema generator can process either Java source files or class files.

       We also provide an Ant task to run the schema generator - see the instructions for using schemagen with Ant.

	  For Solaris/Linux

		% path/to/jaxb/bin/schemagen.sh Foo.java Bar.java ...
		Note: Writing schema1.xsd

	  For WindowsNT/2000/XP

		> path	ojaxbinschemagen.bat Foo.java Bar.java ...
		Note: Writing schema1.xsd

       If your java sources/classes reference other classes, they must be accessable on your system CLASSPATH environment variable, or they need
       to be given to the tool by using the -classpath/-cp options. Otherwise you will see errors when generating your schema.

	  Command Line Options

	     Usage: schemagen [-options ...] <java files>

	     Options:
		 -d <path>	   :  Specify where to place processor and javac generated class files
		 -cp <path>	   :  Specify where to find user specified files
		 -classpath <path> :  Specify where to find user specified files
		 -help		   :  Display this usage message

   Generated Resource Files
       The current schema generator simply creates a schema file for each namespace referenced in your Java classes. There is no way to control
       the name of the generated schema files at this time. For that purpose, use the schema generator ant task.
