I installed Zk Studio following this guide

http://www.zkoss.org/smalltalks/zkstudioins/

but I can’t make it work.
I tried a “-clean” start but still got this error, and can’t open .ZUL editor neither add ZK’s Jar in the preferences dialog.
I have this error:

An error has occurred. See error log for more details.
java.util.Properties.store(Ljava/io/Writer;Ljava/lang/String;)V

and in the log, several errors starting with:

!

jaguarpy,
ZK Studio is not certified to run with MyEclipse. The error that you got suggests that this is a compatibility issue.

[Ale W. Feltes Quenhan]

Then I get for my money a product that is some ways, an improved eclipse, and some others a lesser one? According to plugins list, MyEclipse is based on 3.3 and has WTP, right? What is the “compatibility issue” ?

[Loyal Water]

MyEclipse has WTP integrated in it and you cannot setup the WTP along with MyEclipse. The link you posted mentioned that you need the WTP plugin insalled along with Eclipse 3.3. That could be causing the conflict here. Did you setup the WTP plugin?

BTW, I hope you tried setting up this plugin with MyEclipse 6.5 because that is the version compatible with Eclipse 3.3.

I don’t understand. Sounds like a contradiction to me, “hast but cannot setup” ?

According to you “MyEclipse has WTP integrated”, what exactly does it mean?

BTW, I hope you tried setting up this plugin with MyEclipse 6.5 because that is the version compatible with Eclipse 3.3.

Here it says that MyEclipse 6.0.1 is “full compatible with Eclipse 3.3.x and Europa Projects”.

Is MyEclipse 6.5 worst than 6.0.1 ?
ZK Studio only requires Eclipse 3.3 and WTP (whis is an Europa Project).
I Still don’t understand why can’t I have it running on MyEclipse.

jaguarpy,
Firstly, I’m sorry for the confusion.

Here it says that MyEclipse 6.0.1 is “full compatible with Eclipse 3.3.x and Europa Projects”.

This is correct. MyEclipse is a set of plugins and it HAS to be setup with Eclipse. You can either setup Eclipse separately and then add MyEclipse to it using the Archive installer or you can grab the MyEclipse All in One installer that has Eclipse and MyEclipse pre-integrated and optimized to run together.

Is MyEclipse 6.5 worst than 6.0.1 ?

MyEclipse 6.5 is the newer version of MyEclipse. It is not worst than 6.0.1. Infact it has some bug fixes over 6.0.1.

According to you “MyEclipse has WTP integrated”, what exactly does it mean?

MyEclipse is built ontop of WTP and installing WTP into a MyEclipse install can lead to incompatibilities and breaks.

If you setup the WTP plugin along side MyEclipse, it could cause incompatibilities between the WTP plugin and MyEclipse WTP.

The plugin that you are trying to run with MyEclipse is not certified to run with MyEclipse and Im not sure if it will run if you try to set it up directly with MyEclipse since a prerequisite for this plugin is the WTP plugin. You can try setting this plugin up directly with MyEclipse since it already has Eclipse 3.3 and WTP running. I hope that helps.

Thanks for the response.

If I install MyEclipse through Pulse or Archived Site, can I choose not to install MyEclipse WTP, and later install WTP from Eclipse.org ?
