ImageMagick unable to find the path of convert.exe in packed WAR of Spring boot

I am using ImageMagick to crop image file. I am deploying packed WAR with ImageMagick inside. searchForCmd() function of ProcessStarted class is unable to find the files of ImageMagick from WEB-INF/classes i.e.
file:/D:/Project/build/libs/proj-0.0.1-SNAPSHOT.war!/WEB-INF/classes!/ImageMagick-6.6.1-5
how can I access the convert.exe in packed war .
Below is the stacktrace.

WARs normally do no contain EXEs. If you have dependencies on external applications, they must be installed on the server (or in the container) where the WAR is deployed. Also consider that your Springboot can normally run on a Linux or a Windows server and the IM executable would be different for each...

Java-FX failed to load resource exception

I am running my Java-FX application via webstart by tomcat server.
After signing and versioning of jars I having this problem when am accessing it through web browser.
I am using jnlp and version protocol to start the application through tomcat server.
ExitException[ 3]com.sun.deploy.net.FailedDownloadException: Unable to load resource:
(httP://127.0.0.1:8080/gyms/lib/commons-collections-3.2.1.jar?version-id=1.0.1, 1.0.1)

It seems you are using a jnlp-file with a line like this:
<jar href="commons-collections-3.2.1.jar" version="1.0.1" />
So you are using the version-based download protocol. This will result in the server looking for a file called commons-collections-3.2.1__V1.0.1.jar which apparently is not there.
Bottom line: do not specify two conflicting version-numbers in your jnlp. Decide wether you want to use versioned download and omit the version-number in the href-attribute or use simple download and omit the version-attribute.

Problem is solved because I am using Java 1.7.51 update and also i am usin third api which is not supported in java 8 which is also installed in my desktop.
The program(x86) should not have any version of java greater than java 7 as the application is taking java/bin from x86 only.
that is why that failed download exception is coming at run time.

SmartGwt causes exception in dev mode when I have separate gwt module for view objects

Kindly guide me to resolve following issue.
I have created a separate GWT module for view entities entities.
Following is the structure of my project:
gwt-application : (Presentation related code resides here and I have used GWT-Platform and SmartGwt)
gwt-commons-entities : (GWT Module : This will contain entities to be shared between gwt-applicaiton gwt-service-layer)
gwt-service-layer : (Will contain business logic of the application)
I am facing following exception when I run this application in dev mode (Eclipse -> Run As -> Web Application):

I am not getting such exception when I have my entities in gwt-application.
But I will have to make big architectural changes to my application so I have to put view entities in separate module so that it can be shared.
Appreciate for any clues.

Gotcha. Forgot to call toString() for grid's attribute value. Strange thing observed here it throws above mentioned exception in dev mode however it works fine if generated war of GWT application is deployed in tomcat. GWT caused big pain and cost me 3 days to resolve this.

Java applet fails to reload on Internet Explorer

I have an applet that has a logout"button. The button ends the session by calling a CGI script and then kills Java VM by calling System.exit(). The problem is when a user tries to log in again in the same browser window - the applet fails to load with ClassNotFoundException:
load: class lucent/fm/parts/BlankPage.class not found.

It appears only on Internet Explorer, not in Firefox. Java Plugin is:
Java Plug-in 1.6.0_20
Using JRE version 1.6.0_20-b02 Java HotSpot(TM) Client VM
The direct scenario is the following:
1. Log in to the system (load the applet).
2. Log out (it closes the applet, but the browser window persists).
3. Click on the address bar and press Enter.
4. The applet fails to load and the ClassNotFoundException can be seen in Java Console.
5. Refresh the page - the server redirects to the login page; after logging in, the applet again does not load and throws the exception.
Looking at the Apache access log proved that in the step 4 that the browser (or plugin) tries to load jar files and gets a HTTP error. It is OK because the session has expired. The strange thing happens in the 5th point - there is no request for jars! It seems that the browser or plugin remembers failed attempts and does not even try to load jar files. It only tries to load a raw .class file, which is not present on the server.
Is my conclusion correct? How can I deal with such an error? Is it possible to force Java plugin to load jar files?
I checked that enabling caching in Java Control Panel does not help. Setting the codebase_lookup parameter to "false" is not helpful, too. It only prevents from trying to load the "class" file directly.
Thanks in advance for any suggestions.

I have an applet that has a "logout" button. The button ends the session by calling a CGI script and then kills Java VM by calling System.exit().
An applet calling System.exit(anyNumber) is crudely equivalent to a guest burning down the house of their host. Applets (even trusted applets) should never try to end the VM. The VM will be ended by the browser when all applets in a page that share the VM have finished their destroy() methods and a subsequent period of time as chosen by the browser.
BTW - I recall one version of Mozilla/FF where calling System.exit(int) not just ended the VM, but also crashed the browser!

If your html with applets is not static (cgi, php, etc), then after logging out, you can try to force different URL pointing to the jar file (i.e. instead of "my.jar" use "my.jar?random=1235232").
Also, you can try to play with cache HTTP headers.
Another potential workaround will be to reconfigure apache to serve the jars always - even when session has been closed (if that's acceptable).

Using CXF web service from java web start

UPDATE: I have submitted my question to the CXF User's mailing list, here.
UPDATE: I have currently signed all of my jars. I still can't seem to get CXF setup in a way that it can find the WSDL. My last attempt was to place the WSDL inside of my WAr file so I can access it through a web browser. I set the wsdllocation inside of the client to the URL (http://www.example.com/app/example.wsdl). I am now getting the following exception:
Exception in thread "AWT-EventQueue-0" java.lang.ExceptionInInitializerError
at com.sun.xml.internal.ws.util.xml.XmlUtil.createDefaultCatalogResolver(Unknown Source)
at com.sun.xml.internal.ws.client.WSServiceDelegate.parseWSDL(Unknown Source)

at com.sun.xml.internal.ws.spi.ProviderImpl.createServiceDelegate(Unknown Source)
at javax.xml.ws.Service.<init>(Unknown Source)
Googling has turned up pretty much nothing on this.
I am creating a web service client from a given WSDL using Apache CXF. I am running into problems however when trying to access the service, I get this exception:
Can not initialize the default wsdl from ../resource/example.wsdl
Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.util.PropertyPermission user.dir read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPropertyAccess(Unknown Source)
I am not signing my web start application, and would prefer not to since I am not accessing any resources from the client's machine. The WSDL mentioned is packaged within my jar. The problem is caused by this from the CXF generated client code:
URL url = null;
try {
url = new URL("../resource/example.wsdl");
} catch (MalformedURLException e) {
System.err.println("Can not initialize the default wsdl from ../resource/example.wsdl");
// e.printStackTrace();
}
WSDL_LOCATION = url;
How can I correctly point CXF to this WSDL? I am also worried about the WebService annotation on the class:
#WebServiceClient(name = "Example",
wsdlLocation = "../resource/example.wsdl",
targetNamespace = "http://services.example.com/")
Do I also need to change this?

You are going to need to change that wsdlLocation to a classpath: reference.
use -wsdlLocation as shown here.

After a few mistakes and experimentation, I have managed to get everything to work properly. First, MAKE SURE that cxf.jar and wsdl4j.jar are actually on your classpath. I thought I had verified this, but because I was instantiating the client from inside a jar via webstart that was in itself packed in a WAR, I messed up the placement of the cxf runtime in my build process. Also, when specifying the wsdl location, I had to use "classpath:my.wsdl". I made it easy on myself and just put the wsdl in the same location as my source.
Hope this helps someone who might do the same thing at somepoint!
