Daniel LucioSubject: java extensions
Author: Daniel Lucio

Hi!

I am developing java extensions and I found out that with stylus studio's internal processor, you can not declare a namespace for java like:

xmlns:java="http://xml.apache.org/xslt/java"

And make a call to java object like:

java:myproject.MyClass.myMethod(mydata)

Stylus studio thows a message that says:

"Exception calling Java extension:
java.lang.ClassNotFoundException:http://xml.apache.org/xslt/java
at CXClassLoader........
.
."

Regards

Pd, I tried my script with Xalan on the command line and it worked.

No, that won't work; but if you define:

xmlns:java="myproject.MyClass"

and you use

java:myMethod(mydata)

then both Xalan-J and Stylus Studio should understand it.

Things will get simpler when XSLT 2.0 will be out and all processors will
unify to the specs about extension functions.
And you will probably find Stylus Studio 4.0 useful, as it supports Xalan-J
step-by-step debugging.

Hi Daniel,

The internal processor support the following syntax:

Declaration:
xmlns:MyExt="myproject.MyClass"

Invocation:
xsl:value-of select="MyExt:myMethod()"

The same syntax should be support across different processors : Xalan,
xt, Saxon

Hi!

Well, yes you are right for that. But it happens that we make several calls to different classes, and we do not want to declare a namespace-prefix, for each one of them, as many of them are called once in the script. That is why we are interested in having a general namespace for java like the one I posted in the first message.

Regards!

Hi!

Do you plan to support a namespace for java like xmlns:java="http://xml.apache.org/xslt/java"

so that we can make different calls to java object like:

java:myproject.MyClass1.myMethod1(mydata1)
java:otherproject.MyClass2.myMethod2(mydata2)

??

Regards!

At this point we don't have plans to support that in the Stylus Studio
processor.

But, as mentioned in my previous post, 4.0 will support debugging and
back-mapping through the Xalan-J processor; so, whatever XSLT+Java runs on
Xalan-J, you will be able to debug in Stylus Studio!

4.0 will be in beta in a few days.

Hope this helps,
Minollo
