building net.sf.j2s.ajax (from svn) hangs forever

[asr....@gmail.com]

Hi,

I am trying to build Java2Script (to be able to build JSmol) from SVN (r1211) according to these intructions: http://j2s.sourceforge.net/setup-j2s-from-subversion.html it hangs when building net.sf.j2s.ajax, it just hangs with no message whatsoever. Any ideas? Thanks in advance.

Best

It seems that you need to config servlet jar in .classpath, e.g. 

<classpathentry kind="lib" path="lib/javax.servlet_2.5.0.v200910301333.jar"/>

You can find javax.servlet_2.5.0.v200910301333.jar or other given version in Eclipse's plugins folder.

If you already configure this, what is your error message shown in Problems view?

Hi,

I configured that.

Previously I had <classpathentry kind="var" path="JAVAX_SERVLET"/> with the JAVAX_SERVLET var set accordingly. But I also tried your suggestion.

Still it just hangs forever after doing some compiling: https://www.evernote.com/shard/s21/sh/f0e345af-35cf-4521-9da5-a5350b7c5b4b/bc1e491da46716fc32c4b19e3352e9c6

There are no errors shown in the Problems view

I failed to note that I am on Mac OSX.

What version of Eclipse are you using? Java2Script only supports 3.5 and 3.6 by now.

Java2Script supports Mac OSX, both 3.5 and 3.6 under Snow Leopard and Lion are tested.

Anyway, try to update with these update:

http://dev.zhourenjian.com/j2s/j2s.update.3.5.v20130303.zip

http://dev.zhourenjian.com/j2s/j2s.update.3.6.v20130303.zip

That seemed to work. I used these files http://j2s.sourceforge.net/download.html and then updated them with your updates. So, no SVN. I could then compile JSmol.

Thanks!

Hi Alexander,

I fixed this problem a few days ago. Please update from SVN and rebuild J2S again, if you want to.

The main point of the problem is that Java2Script compiler tries to remove javabuilder, if both of javabuilder and java2scriptbuilder exist in .project file. It runs into a deadlock in doing so.

Here is the modified part of .project in net.sf.j2s.ajax:

<!--

<buildCommand>

<name>org.eclipse.jdt.core.javabuilder</name>

<arguments>

</arguments>

</buildCommand>

-->

<!--

DO NOT enable both javabuilder and java2scriptbuilder,

or Eclipse will be locked in building this project.

If you are building Java2Script from SVN, try to enable

javabuilder and disable java2scriptbuilder first and build

out Java2Script plug-in. And after installing Java2Script,

try to disable javabuilder and re-enable java2scriptbuilder.

-->

<buildCommand>

<name>net.sf.j2s.core.java2scriptbuilder</name>

<arguments>

</arguments>

</buildCommand>

Just comment out javabuilder to avoid deadlock. And compiler sources are also modified to avoid deadlock.
