Issue calling Java Standard Class java.lang.StringBuffer in XSLT Mapping

[Former Member]

Hi Friends,

I have a simple

XSLT mapping in which I have declared "java.lang.StringBuffer" class and used a method like append in it. This mapping is present in PI 7.31 box.

The XSLT code is something like this:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sb="java:java.lang.StringBuffer">

<Record>
  <Name>
   <xsl:variable name="concatname" select="sb:append('A')"/>
   <xsl:variable name="concatname" select="sb:append('B')"/>
   <xsl:value-of select="$concatname"/>
  </Name>
</Record>
</xsl:stylesheet>

It is throwing an error as below:

• javax.xml.transform.TransformerException: com.sap.engine.lib.xsl.xslt.XSLException: -> com.sap.engine.lib.xsl.xpath.XPathException: Illegal number of arguments or types of arguments in a call of function 'sb:append'.

Could any of you advise if this is the right

way of calling the class/method in my XSLT code.

Thank you.

Hi Subbalaxmi,

In sap.help document talks about static method, the java method to be called. May be,  you should to wrap that function in a new one being static. Check the example here (page 12) http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f03df013-289f-2e10-acb9-d1fcf782a...

Hi,

Just one more point to add.

This same code is working in PI 7.0 by directly calling the standard java class in XSLT.

This issue is occuring only PI 7.31.

Hello,

Just a thought - go to OM and tick " SAP XML Toolkit" checkbox and then check?

Hi Amit,

I know it's a bit late and I hope you have fixed this issue by now.

Just for history purposes: have you checked the your JDK version. I know there is a problem with StringBuffer append method. Check the NWDS JDK version and the PI JRE version.

It looks like StringBuffer from Java 1.4 spec will work correctly, but you could be running it against an older JRE (1.3).

Check under Window -> Preferences -> Java -> Compiler -> "Compiler And Classfiles" -> "Compiler compliance level" if you have the same JRE version as you server's.

StringBuffer should be replaced with StringBuilder on newer JRE whenever possible.

Hi

Change this line

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sb="java:java.lang.StringBuffer">

to

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sb="java.lang.StringBuffer">

Hi Indrajit,

Tried, as you told. But still the same issue.
