Hi,

I'm just in the process of porting across some Netbeans 5.x projects to MyEclipse 5.0 GA, and I'm completely stumped as to how I get custom Swing components to work within the built-in Matisse editor.

What I have is a number of *very* simple custom components, (couple of Textfield derivatives and a couple of bespoke table classes) and for the life of me I can't get them to be recognized by the Matisse palette.

I consistently get the following error:

No matter how I try and reference the JAR file containing the custom component.

I've seen other postings here on the forum that seem to suggest that other people have been experiencing similar issues - are there any known workarounds/patches to address this, or will I have to just revert back to NetBeans for the time being?

Cheers

JC

JC,
Sorry for the delay in responding. Just to cut to the quick of this really fast, can you send me your JAR with a list of 2 or 3 of the custom components in an email (support@myeclipseide.com ATTN Riyad, with a link to this thread) and I'll try and import them, and if it fails on my end I'll file it as a bug with the attached JAR to make sure the designer team has something to test against?

JC,
the jar you provided seems to be compiled to be run on a Java6 compliant VM. M4ME is failing when trying to load the widget to get data about it when MyEclipse is run on a 1.5 VM. It works correctly when a 1.6 VM is used.

You can fix you problem by getting a version of the jar compiled for Java5 or less, or you can try to run MyEclipse with a 1.6 VM (these VMs are still beta, and has a number of known problems).
