Can you please create a bug report for this problem. Remember to attach a sample stylesheet, input doc, and expected output.
When you have something like this:
<xsl:param name="e" select="string('a')"/>
<xsl:param name="s" select="java:subSequence($e,0,1)"/>
<xsl:param name="p" select="java:java.util.regex.Pattern.compile('\$[0-9a-zA-Z]+')"/>
<xsl:param name="m" select="java:matcher($p,$s)"/>
the internal representation of $s is an XString object. Before the matcher is invoked, the parameter $s is converted to java.lang.String. However, the method expects CharSequence resulting in an illegalArgumentException. Ideally, all objects that implement CharSequence should be accepted.
Keep in mind that this bug might be marked as an enhancement.
According to http://xml.apache.org/xalan-j/extensions.html#ext-functions, there are limitations due to data type mapping. However, it does not specifically state that an interface cannot be properly mapped.

I have such a statement:
<xsl:param name="e" select="string(@e)"/>
<xsl:param name="p" select="java:util.regex.Pattern.compile('\$[0-9a-zA-Z]+')"/>
<xsl:param name="m" select="java:matcher($p,$e)"/>
This statement is supposed to occur at the beginning of
a template
and retrieve a "e" parameter, then use Java1.4 regexp on it.
Everything works fine, except the last line which throws an IllegalArgumentException.
That's quite strange because: $p is a Pattern, $e is a String
(i checked that with the code given at the end of this message) and p.matcher(CharSequence)
exists in the Javadoc. Please note that the method signature precises "CharSequence"
and $e is a String (which subclasses ClassSequence).
Here is my working debugging code:
<xsl:param name="e" select="string(@e)"/>
<xsl:param name="eClass" select='java:getClass($e)'/>
<xsl:param name="eClassName" select='java:getName($eClass)'/>
<xsl:param name="p" select="java:util.regex.Pattern.compile('\$[0-9a-zA-Z]+')"/>
<xsl:param name="pClass" select='java:getClass($p)'/>
<xsl:param name="pClassName" select='java:getName($pClass)'/>
<xsl:param name="m" select="java:pattern($p)"/>
<xsl:param name="mClass" select='java:getClass($m)'/>
<xsl:param name="mClassName" select='java:getName($mClass)'/>
It works fine and returns expected values for everything.
Any idea?
