    <p>I have a problem that is driving me nuts. Matlab sees only some of my classes embeded in a JAR file</p> <p>If I compile the classes outside of a package and add the path to the class in Matlab using javaaddpath, I do not encounter any problem</p> <p>When I compile the class in a package and then try to access them under Matlab, I have problems. Below some Matlab code</p> <pre><code>&gt;&gt;javaaddpath('/Users/me/Documents/workspace/EKGTest.jar'); &gt;&gt;clear java &gt;&gt;import com.neurosky.thinkgear.* &gt;&gt;methods('EkgSense') Methods for class com.neurosky.thinkgear.EkgSense: EkgSense getClass notify reset addTemplate getClassificationResults notifyAll toString equals hashCode processData wait &gt;&gt;methods('EkgEpoch') No methods for class EkgEpoch or no class EkgEpoch </code></pre> <p>Now, I look in the package, all of the classes are public. This is a result of <code>jar -tf</code></p> <pre><code>osx:/Users/me/Documents/workspace&gt; jar tf EKGTest.jar META-INF/MANIFEST.MF META-INF/REFACTORINGS.XML com/ com/neurosky/ com/neurosky/thinkgear/ com/neurosky/thinkgear/EkgEpoch.class com/neurosky/thinkgear/EkgEpoch.java com/neurosky/thinkgear/EkgParameters.class com/neurosky/thinkgear/EkgParameters.java com/neurosky/thinkgear/EkgTemplate.class com/neurosky/thinkgear/EkgTemplate.java com/neurosky/thinkgear/Matlab.class com/neurosky/thinkgear/Matlab.java com/neurosky/thinkgear/EkgSense.class com/neurosky/thinkgear/EkgSense.java com/neurosky/thinkgear/DistanceArray.class com/neurosky/thinkgear/DistanceArray.java </code></pre> <p>and below of <code>javap --classpath</code></p> <pre><code>osx:/Users/me/Documents/workspace&gt; javap -classpath /Users/me/Documents/workspace/EKGTest.jar com.neurosky.thinkgear.EkgEpoch Compiled from "EkgEpoch.java" public class com.neurosky.thinkgear.EkgEpoch extends java.lang.Object implements java.lang.Cloneable{ public int numberOfSamples; public float[] data; public com.neurosky.thinkgear.EkgEpoch(int); public com.neurosky.thinkgear.EkgEpoch(int, float[]); public com.neurosky.thinkgear.EkgEpoch(float[]); public com.neurosky.thinkgear.EkgEpoch(com.neurosky.thinkgear.EkgEpoch); public com.neurosky.thinkgear.EkgEpoch(org.json.JSONArray); public org.json.JSONArray toJSONArray(); public static float[] convolve(float[], float[]); public float getLineNoiseAmplitude(); public com.neurosky.thinkgear.EkgEpoch subtract(com.neurosky.thinkgear.EkgEpoch); public com.neurosky.thinkgear.EkgEpoch subEpoch(int, int); public com.neurosky.thinkgear.EkgEpoch square(); public com.neurosky.thinkgear.EkgEpoch subtract(float); public com.neurosky.thinkgear.EkgEpoch diff(); public boolean exceedValue(float, int, int); public com.neurosky.thinkgear.EkgEpoch smooth(int); public float mean(); public float sum(); public float max(); public float median(); public com.neurosky.thinkgear.EkgEpoch clone(); public com.neurosky.thinkgear.EkgEpoch sort(); public int[] sortIndices(com.neurosky.thinkgear.EkgEpoch); public float std(); public int find_heart_beats(int[], float); public com.neurosky.thinkgear.EkgEpoch detrend(); public java.lang.Object clone() throws java.lang.CloneNotSupportedException; } osx:/Users/me/Documents/workspace&gt; javap -classpath /Users/me/Documents/workspace/EKGTest.jar com.neurosky.thinkgear.EkgSense Compiled from "EkgSense.java" public class com.neurosky.thinkgear.EkgSense extends java.lang.Object{ public com.neurosky.thinkgear.EkgParameters params; public com.neurosky.thinkgear.EkgTemplate[] templates; public com.neurosky.thinkgear.EkgTemplate currentData; public int lastTemplateInd; public float lastEpochValue; public com.neurosky.thinkgear.EkgSense(com.neurosky.thinkgear.EkgParameters); public void reset(); public void addTemplate(java.lang.String, float[][]); public void addTemplate(com.neurosky.thinkgear.EkgTemplate); public java.lang.String getClassificationResults(); public boolean processData(float[]); } </code></pre> <p>I am running Matlab on OSX. I have tried with Matlab 7.7.0.471 (R2008b) and 7.11.0.584 (R2010b) and got the same problem. Both Matlab are using the native OSX Java (Java 1.6.0_26-b03-384-10M3425 with Apple Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode) which should be the same as the one in Eclipse (I have checked and Eclipse compiles with 1.6).</p> <p>Remember that I can see the missing class no problem when I remove the package statement and some imports at the top of the java files (in all the classes of course) and when I simply add the path to the .class files (not access them in a JAR file).</p> <p>Any help would be greatly appreciated. Thanks,</p> <p>Jason</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
