What steps did you take that resulted in the issue?
Tried to redeploy a WAR file. Restarted TomCat,Eclipse

What application server are you using?

————————————————-

MyEclipse failed to redeploy even though the virus scanner was disabled…..Was working OK and then stopped working. Was also using Packaged instead of Exploded when deploying.
Had to delete files from the Tomcat directory and close Eclipse down and Stop and Start Tomcat. Then the deploy would work again but only for a short time.

This is a very difficult problem to fix, the reason is file locks performed by Tomcat. The problem is that if you do exploded deployment, Tomcat will lock your libraries (JARs) causing consecutive deployments to fail. Sometimes this fails right away, othertimes it takes longer.

With packaged deployment, the chances are slimmer that you will run into this problem, but still Tomcat will get a lock on the deployed JAR when it uncompresses it and it seems sometimes the locks don’t expire in a timely fashion. I run into this problem a lot as well and its not MyEclipse’s deployment fault, as when I drop to the command line or open up Windows Explorer, I cannot delete the file ‘because its currently in use’.

We are, however, working hard on making this process more streamlined. 2.7 GA will include improvements in this area (more user feedback) and 2.8 will include more features related to deployment. I don’t know if this is helpful, but I didn’t seem to run into any deployment problems with Tomcat 5.0.14, but since Tomcat 5.0.16 and up (5.0.18) I run into deployment problems all of the time. I’m wondering if Tomcat’s file handling code for the JAR files has changed?

Hello;

I have a similar problem; I can not remove the Deployment.

Saludos,
If you run into the situation where you cannot remove the deployment, just restart Eclipse and the faulty deployment will be gone. Let me know if this works.

[Alejandro Rico]

Thanks,

Yesterday I had previously Closed and Reopen Eclipse and the situation remained; but today -as you said- the problem is gone. 8)

Saludos

I always say a little prayer before doing it 😀
