Hi Marco,

There seems to be some kind of linkage problem since we never actually succeded in linking eclipse with basex ("Error: Could not find or load main class") even when following the tut at: http://docs.basex.org/wiki/Integrating_Eclipse

What’s the complete error message? Do you have some more information on the Eclipse and BaseX version you have tried? It should work fine with any recent version of BaseX, Eclipse Indigo and the XQDT update link, and most other configurations we have tried so far.

Hm, sounds alright so far. Maybe it’s about the location of your directory. Could you send me a little screenshot of your BaseX XQDT configuration ("Edit Interpreter" dialog)? I’ll then try if I can reproduce it with Ubuntu. ___________________________

Hi Chris, when I set BaseX to be the engine as described in the tutorial on the wiki. Then I create an xquery project and an xquery module. I try to run the module through an xquery run configuration and the only thing I can see is the following message in the console view:

Error: Could not find or load main class

There is no error or exception in the .metadata/.log of the Eclipse workspace.

I use Indigo, BaseX 7.5, Zorba's xqdt build 1.0.0.201108251748. Everything on Ubuntu 12.10.

May there be any classpath related issues? Does the directories' location matter? Dunno.

Thanks, M.

Oh, fine will give it a try immediately. M.

Hi Marco and Christian,

I had the message "Could not find or load main class", following the instructions from http://docs.basex.org/wiki/Integrating_Eclipse for setting up as client, after yet adding "-Xmx512m" at "Java arguments:" it worked for me. (Got this idea just from looking into the bin/basex sart script within the basex installdir, not yet spend more thoughts on the background...)

Regards, Joern.

I believe the XQDT debugger only works for Zorba [1]. It would be great to see a debugger for BaseX but it would be a lot of work. [2] might provide some useful tips.

Perhaps a first step would be to define event interfaces for points in the XQuery execution that a debugger might want to hook into. This could also be used for profiling.

As a very poor mans debugger: adding the *System.out *calls below to src\main\java\org\basex\query\func\StaticFunc.java will show the start and end of function calls.

/Andy

public Value invValue(final QueryContext ctx, final InputInfo ii, final Value... arg) throws QueryException { // reset context and evaluate function final Value cv = ctx.value; final StaticContext cs = ctx.sc; ctx.sc = sc; ctx.value = null; final int fp = addArgs(ctx, ii, arg); *System.out.print(">"); System.out.println(this.name);* try { final Value v = ctx.value(expr); // optionally promote return value to target type return cast ? declType.funcConvert(ctx, info, v) : v; } finally { scope.exit(ctx, fp); ctx.value = cv; ctx.sc = cs; * System.out.print("<"); System.out.println(this.name);* } }

After doing the Xmx trick suggested by Joern, I'm finally able to run XQueries on BaseX from inside Eclipse. But yet when I try to run the debugger I get the following error in a popup:

Title: Interpreter runner not found Interpreter runner not specified for install 'basex' and mode 'debug'.

Any other hint? M.

Hi Rob,

I was hoping to read "I really could do a nice debugger" ;) …but, yes, it would surely be possible and absolutely desirable. Can’t promise, though, when it will happen, who will do it, and if it will be included in Eclipse, oXygen, or our own GUI. Are there any volunteers out there?

Hi,

Making intensive use of mappings {} and high-order recursive functions, I really could do with a nice debugger for the Xquery in BaseX.

Is a debugger in the planning?

Thnx.
