Hi,
Well , i have figured out the problem.
The command :
java org.apache.xalan.xslt.Process -in test.xml -xsl test.xsl -out out.xml
first searches for the java class along with package name ( tester.xyz ) in
the same directory where the xsl and xml are.
If class is not found in the relative path it looks in the classpath
specified in the command
for example: java -cp "C:" org.apache.xalan.xslt.Process -in test.xml -xsl
test.xsl -out out.xml
and if still not found it looks in the system classpath (Environment
variable if any).
In my case wrong file was being picked ( i had a class xyz placed in the
directory tester in the same directory as my xml and xsl ), While i was
updating any changes to class xyz in some other location.
Well I know it has been a goof-up, but this can act as a lesson to all of
us. RIGHT?
Thanx for your answers and cooperation.
Regards
Manpreet

Subject: [xsl] Problem in calling external java function
Importance: High
Hi,
The following is the xslt code calling a java class:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:test="C://tester"
exclude-result-prefixes="test">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="b">
<xsl:variable name="test1"
select="test:xyz.new('A;B;C',';')"/>
<abc>
<xsl:value-of select="test:getNextToken($test1)"/>
</abc>
</xsl:template>
</xsl:stylesheet>
The following is the code for the class being called:
import java.util.StringTokenizer;
public class xyz {
private StringTokenizer tokenizer;
public CreateMultipleTargetInstance( String specimen, String token ) {
tokenizer = new StringTokenizer ( specimen, token );
}
public String getNextToken() {
if ( tokenizer.hasMoreTokens() ) {
return tokenizer.nextToken();
}
else {
return "";
}
}
}
When i call this class using the above xslt Through command prompt using the
following command:
java org.apache.xalan.xslt.Process -in test.xml -xsl test.xsl -out out.xml
i get the following error:
file:/C:abc.xsl;
Line #9; Column #-1; XSLT Error (javax.xml.transform.TransformerException):
java.lang.NoSuchMethodException: For extension function, could not find
constructor
tester.CreateMultipleTargetInstance([ExpressionContext,] #STRING, #STRING).
The xslt is supposed to return me the first string before ";" i.e A.
...........ANYONE?

Manpreet
