How to make eclipse validate jsp files automatically - eclipse

I have search for an Option in eclipes to let him validate the contents of JSP files automatically when the workspace ist compiled.
I didn't find any usefull results.
Do you have an idea how to do that?

You can do this via a project builder Ant build file.
See Eclipse help: Creating a project builder Ant buildfile
The org.eclipse.help.webapp project does the same:
The Ant build file to compile the JSP files
The Ant file added as project builder (to automatically run the Ant script when the workspace ist compiled)

How to generate build file for project in Netbeans

I know eclipse can automatically create a build file for a given project through its inbuilt wizard (Export->General->Ant File).
But wondering how to do the same if my project is in Netbeans.
Does NetBeans also provide a similar wizard screen to create build file. If not, any other way around.?
NetBeans uses Ant as its build system. Ant build script is already there (unless you used Maven project type).
Some related questions are linked in How do I build ant's build.xml using NetBeans?
I could not find to create build file from Netbeans. But found a workaround, by creating a build for my project in eclipse and then modifying it to suit to netbeans project structure.

TestNG test cases not auto compiling in Eclipse

I have a Maven project imported as General --> existing workspace into my eclipse.
When i write a new test file or edit an existing test file, the file does not seem to auto build. My build path is correct and the test out put folder is in \target\test-classes
any help here?

Automatic Build for Non-Java Eclipse Project

I have a project that contains xml files. I also have an Ant build in that project to generate documentation based on the xml files. The Ant build calls a Ruby script for generation.
I would like a way run that Ant build after the modification of any resource in the "{project}/xml" folder. I know that I can right click on the build.xml and Run As->Ant Build, but I want it to be more like the incremental build for Java projects. I have tried creating a builder, importing the Ant build and setting up relevant resources, but when I make a change to the XML file, a build does not start. I have "Build Automatically" checked for the project as well.
This must be possible. What am I missing?
A custom builder will only run when a file is saved that is in a source directory. Make sure the /xml folder is included as a source location in the Project Properties, Java Build Path.

NetBeans -- Is it possible to bypass the IDE-generated Ant build for an existing project?

I have a Java project with sub-projects that is currently built using NetBeans's IDE-generated Ant scripts. I am converting the entire project to a Maven build.
My Maven build works fine from the command line and loads perfectly in Eclipse. However, the only way I can get the project to load as a Maven project in NetBeans is to delete the Ant scripts, i.e. build.xml and the directory nbproject for each sub-project. It seems that as long as I have the old IDE-generated build files, NetBeans recognizes the project as a NetBeans Java project only, not as a Maven Java project, even though there is also a pom.xml file present.
Short of deleting the IDE-generated build files, is there any way to tell NetBeans to load the project as a Maven project?
I have been told that we want to keep the Ant build for a while during the transition to Maven.
Using NetBeans 6.9.1, Maven 2.2.
Any help would be appreciated.
Thanks
Well, the nb ant project metadata has precedence over occurence of pom.xml file (that's how maven projects are recognized and loaded). The whole precedence order hardwired in the IDE, you could only influence it be uninstalling the j2se ant project type for example.
So, yes. You need to get rid of the ant project metadata before you can open the project as maven project. Depending on how and when you delete the metadata, you might need to restart the IDE as well to get the new stuff loaded.
Have you seen http://wiki.netbeans.org/MavenBestPractices? It indicates that you must install the NetBeans maven plugin first. Perhaps that's why your Maven projects aren't recognized.
I must note that I'm not a NetBeans user anymore!
Here is what I ended up doing:
I wrote an Ant script (ironic, huh?) that, for every subproject of my project, renames the file nbproject/project.xml if it exists to nbproject/nb_project_disabled.xml. If nbproject/nb_project_disabled.xml exists instead, the script renames it back to nbproject/project.xml. In this way, the script toggles the opening of the project as a NetBeans Ant build or as a Maven build.
It would be nice if NetBeans, you know, had a setting to open both kinds of projects. Currently (6.9.1), there is just the "Open Project" command. In Eclipse, there is the command "Import Existing Maven Projects" vs. "Import Existing Project Into Workspace" (i.e. native Eclipse format).

Build eclipse project with ant

I am developing JSR 268 compliant portlet and utility with eclipse.
Now, the utility is designed to be a separate JAR from the portlet itself.
Does anyone now how to write an ant build.xml that will
1. Compile and JAR my utility class
2. Move the JAR to the ./lib folder of the portlet
3. Compile and maybe even delpoy the portlet to a tomcat running on localhost?
My biggest problem right now are the build-time dependencies. I dont want to hardcode all the folders as I share this project with two other developers which are on another platform.
Is it possible to reuse the buildpath from eclipse?
Thank you in advance,
Felipe
Does this wizard help
Rigth-click on project -> Export ... -> Ant buildfiles.
?
Though you probably have figured something out by now, for future references I would suggest taking a look at Eclipse's ability to use Ant files as project builders.
An advantage of this is, that will happen automatically as you build and since you only pack and copy the jar file, you don't have to worry about changes in e.g. the class paths, as you would in the two previous answers
Create a ant file that jar the utility project. Follow: [1]
Add it as a ant-builder to your utility project as described in [1]
Now Eclipse will automatically generate the jar file every time you build.
Extend the ant script to also copy to jar file to the lib dir.
Eclipse have ant task to convert workspace/project relative paths to
normal file paths. See [2]. Note that for those tasks to work, you must select ''Run is the same JRE as the workspace'' under the ''JRE'' tab when configuring the ant builder
In order to ensure your utility is build first add a project reference from your portlet to your utility project right click > properties > project references
When you build the following will now happen:
You utility project will build first, because of the project reference
The ant-builder will pack the jar, and copy it to the lib folder.
You portlet project will build using the new jar.

For 1. Just use the and Ant tasks
For 2. Is it on a remote server? How do you get it there? Windows share?
For 3. Set up the Tomcat manager and then use Tomcat's deploy/undeploy Ant tasks:
http://blog.techstacks.com/2009/05/tomcat-management-setting-up-tomcat.html
<taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask" />
<taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask" />
If you want to avoid hard-coding paths, try to use relative paths. Where are you dependencies right now? What do you feel you may have to specify an absolute path for?
In Eclipse,
Goto Window->preference->Ant->Runtime->Classpath->ant Home
Then add what are the thing u need to add,atlast click ok button to create ant file.
