Nature does not exist: com.bostechorp.cbesb.ui.ide

[ama1]

Hi,
I am facing that error, when I try to create a new Chainbuilder ESB Project:

Problems encountered while setting project description.
Nature does not exist: com.bostechcorp.cbesb.ui.ide.13.

I am using the latest Chainbuilder release 1.3m1 together with JDK 1.5.0_11.

Could anyone help me with that issue?

thanks,
Patrick

Hi Patrick,
Try right clicking on your project, there should be an option called "Convert Project Nature". Inside that option should be a selection for "Convert to Project of Latest Version". Select this, and it should update your project with the missing project nature. This action will need to be done to any project that was created with a previous version of Chainbuilder ESB to bring any configuration files up to the latest version.

Thanks,
Mark Preston

Hi Marc,
no sorry, but that does not help. I created a new project and the error occurs.
Regarding the error message he misses the class: com.bostechcorp.cbesb.ui.ide.util.ESBProjectNature

If i look under <installDir>/eclipse/features or plugins
I indeed find no com.bostechcorp.* package.

Maybe the download was corrupt? or do I have to search elsewhere?

Thanks,
Patrick

Patrick,
We don't have any Chainbuilder related files in the eclipse/features folder, however we do have 24 com.bostechcorp.cbesb.* files in the eclipse/plugins folder. If you have all 24 in that location, your installation is probably OK.

In your project folder, there should be a .project file. The Eclipse Package Explorer view hides this, so you will have to switch to the Navigator view or just use Windows Explorer to view it. If you open that file, the contents should look similar to:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>MyProject</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
</buildSpec>
<natures>
<nature>com.bostechcorp.cbesb.ui.ide.jbiproject</nature>
<nature>com.bostechcorp.cbesb.ui.ide.13</nature>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
</projectDescription>


At the end of the file, you see the natures section. The error you are seeing may be because you project does not have the com.bostechcorp.cbesb.ui.ide.13 nature listed in this file. Can you check if your .project file contains this? If not, try adding it manually and see if that fixes the issue.

Thanks,
Mark

Hi Marc,
I looked at the jars in the plugin folder. But I found only 22 com.bostech* jars:
com.bostechcorp.cbesb.common.mdl_1.3.0.jar
com.bostechcorp.cbesb.common.trn_1.3.0.jar
com.bostechcorp.cbesb.common.util.xfm_1.3.0.jar
com.bostechcorp.cbesb.common.util_1.3.0.jar

com.bostechcorp.cbesb.ui.util_1.3.0.jar
com.bostechcorp.cbesb.ui.variant.editor_1.3.0.jar

That was the install archive: "cbesb-1.3_M1_041708_install.zip"
May you have an idea what is wrong?

Thnx,
Patrick

Patrick,
I forgot to mention that there is a difference between the Community Edition, which is what you installed, and the Professional Edition. The Community Edition will have 22 files, the Professional Edition has 24.

Hello Mark,

I'm having the same problem under CentOS 5.1 with Java 1.5.

I've tried the workaround, but that does not result in a project that works. Specifically, if I create a JBI Service Assembly project and try to add a reference to my original ESB project (modified with the workaround) it is not possible because the ESB project never shows up in the refrence window.

Additionally - if I attempt to change the nature of the original project (right click and select Modify Nature), I get this error:

Can not convert project:org.eclipse.core.runtime.CoreException: Problems encountered while setting project description./nStatus ERROR: org.eclipse.core.resources code=568 Problems encountered while setting project description. null children=[Status ERROR: org.eclipse.equinox.registry code=1 Plug-in com.bostechcorp.cbesb.ui.ide was unable to load class com.bostechcorp.cbesb.ui.ide.util.ESBProjectNature. java.lang.ClassNotFoundException: com.bostechcorp.cbesb.ui.ide.util.ESBProjectNature]

Any idea? We have 24 cbesb plugins.

Thanks,

Hi,
yes you are right, my project was at the end still buggy after the work-around.
But that was a problem with the comunity edition. After downloading the Professional Edition I had no problems and could finish the Getting Started example.
But it looks like that you have already the Prof. ?

Hello Ama1,

I tried installing the Professional version additional components on Linux (basically untarred the Professional add-on into the cbesb-1.3 directory), and I'm still getting the same error. Back to the etch-a-sketch...

Thanks,

Hi,

I had the same problem with CB 1.3.3 Community edition on Ubuntu 8.04

I did not have set environment variables correctly
CBESB_HOME
SERVICEMIX_HOME
ANT_HOME
PATH
ECLIPSE_HOME

After I have put them into my .profile, creation of Chainbuilder project worked correctly.
