We'd like it to use ant and work on svn check-in to the x3d-code/<a href="http://www.web3d.org">www.web3d.org</a> folder on sourceforge. Please give me a figure for the amount you want to be paid for this work. We'd like to be able to fire off builds from the web as well. Please check all configuration files except passwords into GitHub. Ultimately I think we will have Leonard or someone follow up after you to install on a web3d server, so be sure to create documentation on what you did.

People can then download products directly from the ci server when they see something is successful. And there's likely a date associated with the product. So you can have your history of products as well. It really is quite nice. I guess I'd go with oracle's ci server if it's free.

Don,<br>
<br>
Hmm. Maybe set breakpoints by the ProtoInstances and ProtoDeclare. I can bring up in the debugger, but so far, I haven’t been running any IDE. Would be nice if we could “Create new X3DSAIL project” in an IDE (hint, hint).<br>
<br>
I would say it’s nested prototypes which are thwarting the current algorithm, but would have to put it under a debugger to make sure. I’m getting a lot of these fieldValue errors. You should at least write out to one format in your app code, maybe provide methods for each format, with an output file parameter.<br>
<br>
We should investigate uploading a version of X3DJSAIL to a Maven 2 repository for testing with Maven and IDEs.<br>
<br>
What you probably should do is create a maven POM for building X3DJSAIL. I can probably help, but will require source to be in PROJECT/src/main/java/org/… as per normal Maven projects—that is, I don’t know how to use stylesheets in Maven, except that it probably goes in the generate-sources phase. The pom.xml will go in PROJECT. Your example will go in PROJECT/src/test/java/. resources (stylesheets) go in PROJECT/src/main/resources/.<br>
<br></div>
Time to advance to the state of the art for both of us? I’ve been writing shell scripts **blush**.<div class="m_3743288039673372564quoted-text"><br>
<br>
I will write a test project once the main X3DJSAIL pom is written.<br>
<br>
This will make X3DJSAIL palatable for the majority of Java programmers, and will allow for versioning, etc.<br>
<br>
Should we set up a meeting to go over Maven? Roy?<br>
<br>
I’m wearing out my processors running 8 jobs at a time. Any chance I can get consortium resources once we get these maven projects built and put into continuous integration. That is, an account on the continuous integration web page? I’d like to see the whole thing built and redeployed automatically (if build is successful) whenever something is checked in. I do believe this is very realizable. We can set up separate projects for each JSAIL language.<br>
<br>
Should I be working towards a JNI version of X3DJSAIL for C++, or go to back to python and work on the serializer there (in addition to tracking down runtime issues—in any language)? Or push forward on Nashorn? IKVM (convert jars to dlls) may be the best solution for python, C# (windows).<br>
<br>
I’m getting many more code too large with the function Java style. Perhaps it’s not a good approach if it has more compiler errors than the more typical java approach?<br>
<br>
Getting the rest of the append errors solved is probably highest priority for me.<br>

looks like you have nested prototypes here. so if you are sure protos are declared before they are instanced, that may be thwarting the current algorithm and will require further sleuthing.<br>
