My small code is of XSL is:
<xsl:stylesheet version = '1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform' xmlns:XYZ="http://www.oracle.com/XSL/Transform/java/pack/XYZ">
<xsl:template match="PatientRecord">
<patientKey>
<LastName>
<xsl:value-of select="XYZ:getValue()"/>
</LastName>
<DOB>
<xsl:value-of select="DOB"/>
</DOB>
</patientKey>
</xsl:template>
</xsl:stylesheet>
My small code of java is :
package pack;
public class XYZ{
public String getValue(){
return "Hello World";
My small piece of XML is:
<PatientRecord>
<RecordType>P</RecordType>
<FirstName>JAVA</FirstName>
<LastName>DEVELOPER</LastName>
<SSN>737747777</SSN>
<DOB>19740310</DOB>
<DoctorID>20874</DoctorID>
<VisitReason>
Programming stress disorders
</VisitReason>
</PatientRecord>
I added the xmlparserv2.jar and xyz.jar file to classpath and XYZ.class file is in xyz.jar file .
Could any body help me if they have encounter or know the answer.
Thanks,
Reddy

Answer 1

This occurs because of a bug in the IBM JVM's JIT compiler. You should file a bug with IBM to get this fixed, using your stylesheet as a testcase. Lots of people have hit this problem.
Disable your JIT compiler (or switch JVM's) and you won't have the error.
