Problem deleting jar packaged item from repo
Hi, If I install HelloWorld.jar to the repository as described at [1] It all works. However attempts to remove the item generate: [bxerr:BXRE0001] Package 'org.basex.modules.Hello' does not exist. /Andy [1] http://docs.basex.org/wiki/Repository#Java
…fixed, thanks! PS: As the bugs you report are always bugs, and no misunderstandings, free to add them in our GitHub issue tracker! If you prefer the list, that’s fine as well. On Wed, Apr 6, 2016 at 6:20 PM, Andy Bunce <bunce.andy@gmail.com> wrote:

Thanks, works for me. Here is a follow on question :). I have used Gunther's updated REx to create a jar [1] from CR_xquery_31_20151217.ebnf (just as an experiment I put it in package org.basex.modules in this case - but I don't think this matters here) If I put the jar in basex/lib then it works. I can do: Q{org.basex.modules.CR_xquery_31_20151217}parseXQuery("42") If instead I install it to the repo. It appears as "org.basex.modules.CR_xquery_31_20151217" but import module namespace p="org.basex.modules.CR_xquery_31_20151217"; Fails with Could not instantiate org.basex.modules.CR_xquery_31_20151217: org.basex.modules.CR_xquery_31_20151217 Any ideas where the problem could be? /Andy [1] https://github.com/expkg-zone58/ex-xparse/releases/download/v0.2.1/CR_xquery...

It sounds as if it’s not possible to create an instance of this class. Could you possibly forward the stack trace (triggered by -d)?

Thanks! @Gunther: Do you think such a dummy constructor could be added to the Java class?

I need to get deeper into Java. I can't see why Java's Default Constructor [1] rule does not apply here? /Andy http://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.8.9 On 7 April 2016 at 17:58, Christian Grün <christian.gruen@gmail.com> wrote:

Thanks! @Gunther: Do you think such a dummy constructor could be added to the Java class?

Well, me neither ;) Maybe it’s got to do with the way we instantiate the class via reflection? I didn’t track this down yet (I should probably do so).

Hi Gunther, I agree, it wouldn’t make too much sense to add a default constructor to your code as long as there is the one-argument constructor that will be called by the parseXQuery function. The reason why a default constructor is required in BaseX is because "import module" will always create an instance of the imported Java class, which can then be addressed in the XQuery code, using the assigned prefix [1]. @Andy: For creating a BaseX module, you could add another simple Java class, which will then call the actual parser class: import org.basex.query.value.item.Str; import org.basex.query.value.node.ANode; public class XQuery31Parser { public ANode parseXQuery(Str str) throws IOException { return CR_xquery_31_20151217.parseXQuery(str); } } Hope this helps, Christian [1] http://docs.basex.org/wiki/Java_Bindings#Module_Imports On Thu, Apr 7, 2016 at 11:54 PM, Gunther Rademacher <grd@gmx.net> wrote:
Hi Andy, Christian,
a default constructor is added implicitly, when a class does not provide any constructors itself. A REx-generated class however comes with a constructor. In that case any instantiation must provide arguments for some defined constructor.
However I do not see a real reason for instantiating the class at load time. The generated parse function is static and it takes care of instantiating a parser object internally.
I just did a quick test and found that I see this instantiating problem when using "import module namespace ...". No problem when using "declare namespace ...." or just an EQName literal instead. I have put my extension function class files into the classpath for checking this.
Am I missing something here?
Best regards Gunther

I can't see why Java's Default Constructor [1] rule does not apply here?
Well, me neither ;) Maybe it’s got to do with the way we instantiate the class via reflection? I didn’t track this down yet (I should probably do so).

No constructor is the issue. Adding public CR_xquery_31_20151217() {} to java src fixes it.
Thanks! @Gunther: Do you think such a dummy constructor could be added to the Java class?
